DEMOLITION OF HANFORD'S 232-Z WASTE INCINERATION FACILITY

International Nuclear Information System (INIS)

LLOYD, E.R.

2006-01-01

The 232-Z Plutonium Incinerator Facility was a small, highly alpha-contaminated, building situated between three active buildings located in an operating nuclear complex. Approximately 500 personnel worked within 250 meters (800 ft) of the structure and expectations were that the project would neither impact plant operations nor result in any restrictions when demolition was complete. Precision demolition and tight controls best describe the project. The team used standard open-air demolition techniques to take the facility to slab-on-grade. Several techniques were key to controlling contamination and confining it to the demolition area: spraying fixatives before demolition began; using misting systems, frequently applying fixatives, and using a methodical demolition sequence and debris load-out process. Detailed air modeling was done before demolition to determine necessary facility source-term levels, establish radiological boundaries, and confirm the adequacy of the proposed demolition approach. By only removing the major source term in equipment, HEPA filters, gloveboxes, and the like, and leaving fixed contamination on the walls, ceilings and floors, the project showed considerable savings and reduced worker hazards and exposure. The ability to perform this demolition safely and without the spread of contamination provides confidence that similar operations can be performed successfully. By removing the major source terms, fixing the remaining contamination in the building, and using controlled demolition and contamination control techniques, similar structures can be demolished cost effectively and safely

Schartmann, F.; Thierfeldt, S.

2008-01-01

The 'Quality Assurance and Demolition Symposium, which has become a tradition established jointly by Applus RTD Deutschland GmbH (formerly compra GmbH) and Brenk Systemplanung GmbH, Aachen, was held also in 2008 with the focus on quality assurance and the demolition of nuclear facilities. The conference began with a series of lectures on knowledge and document management in general, and the use of document management systems in the nuclear field in particular. The evening lecture was presented by Axel Weis (Karlsruhe Research Center) on 'Competence Preservation in Nuclear Technology'. The 24 technical papers presented on the next 2 days of the symposium dealt with non-destructive materials testing and with special problems of radiation protection, demolition, and waste management. In 2009, the meeting will cover similar main topics and will again be held in an interesting environment, perhaps in combination with a tour of a demolition project. (orig.)

We assessed whether 2 types of public housing-scattered among market-rate housing developments or clustered in small public housing projects-were associated with the perceived health and health behaviors of residents' social networks. Leveraging a natural experiment in Montgomery County, Maryland, in which residents were randomly assigned to different types of public housing, we surveyed 453 heads of household in 2011. We asked residents about their own health as well as the perceived health of their network members, including their neighbors. Residents in scattered-site public housing perceived that their neighbors were more likely to exercise than residents of clustered public housing (24.7% of network members vs 14.0%; P housing have a modest impact on the health composition of one's social network, suggesting the importance of housing policy for health.

Demolish or refurbish – Environmental benefits of housing conservation

Directory of Open Access Journals (Sweden)

Grace Ding

2013-06-01

Full Text Available Climate change and energy efficiency are some of the most pressing issues facing China today. With its economic growth since 1978, the government has struggled to contain environmental damages and social unrest related to the economy’s rapid transformation. With the rapid growth in population and urbanization the demand for housing has escalated and traditional housing has been under threat of demolition to make way for new construction. Traditional housing is generally considered wasteful in its use of land and/or energy, and is often demolished for more intensive and more energy-efficient housing, despite the resulting loss of embodied energy and urban amenity. A research project was undertaken to study the environmental performance of traditional housing in Hangzhou. The project looks into analyzing and comparing embodied energy and CO2 for seven dwellings. In addition indoor climate data were recorded and collected in the form of hourly temperature and humidity readings for one year in six local houses and in a modern unit as a control for one year. The research results reveal that there is little difference in environmental performance between traditional and conventional modern construction and the value of conservation rather than demolition as a strategic development for the construction industry.

Handling construction waste of building demolition

Directory of Open Access Journals (Sweden)

2018-01-01

Full Text Available Some building defects lead to their demolition. What about construction and demolition waste? According to the Waste Act 185/2001 Coll. and its amendment 223/2015 Coll., which comes into force on January 1, 2017, the production of waste has to be reduced because, as already stated in the amendment to Act No. 229/2014 Coll., the ban on landfilling of waste will apply from 2024 onwards. The main goals of waste management can thus be considered: Preventing or minimizing waste; Waste handling to be used as a secondary raw material - recycling, composting, combustion and the remaining waste to be dumped. Company AZS 98 s. r. o. was established, among other activities, also for the purpose of recycling construction and demolition waste. It operates 12 recycling centers throughout the Czech Republic and therefore we have selected it for a demonstration of the handling of construction and demolition waste in addressing the defects of the buildings.

2016-01-01

Affordable housing is an important form of income security for low-income older persons. This article describes characteristics of older persons waitlisted for either public housing or a housing choice voucher (HCV; previously Section 8) in Portland, Oregon. 358 persons (32% response rate) completed a mailed survey with questions about demographics, health and housing status, food insecurity, and preference for housing with services. Findings indicate that many waitlisted older persons experienced homelessness or housing instability, poor health, high hospital use, and food insecurity. Public housing applicants were significantly more likely to report lower incomes, homelessness, and food insecurity than HCV applicants. We conclude with policy implications for housing and health agencies that serve low-income older persons.

Sustainable solutions for Dutch housing. Reducing the Environmental Impacts of New and Existing Houses

Energy Technology Data Exchange (ETDEWEB)

Klunder, G.

2005-04-12

Sustainable housing construction and management has, to date, been primarily based on an intuitive approach. Numerous measures have been formulated to promote sustainable construction and to reduce the environmental impacts of the built environment. However, little is yet known about the extent of the environmental benefits thereof. Moreover, methods and tools are mainly directed to new construction. This thesis makes clear that short-term environmental benefits in sustainable housing construction are rather limited. Renewal of the post-war housing stock offers excellent changes for improvement of the environmental performance of housing. With a newly developed method it is proven that renovation causes less environmental impacts than demolition followed by new construction. However, at the same time the usefulness of Life Cycle Assessment for buildings is doubted.

A Sandia National Laboratories decontamination and demolition success story

International Nuclear Information System (INIS)

Miller, D.R.; Barber, D.S.; Lipka, G.

1994-01-01

Sandia National Laboratories/New Mexico (SNL/NM) has established a formal facility assessment, decontamination and demolition oversight process with the goal of ensuring that excess or contaminated facilities are managed in a cost-effective manner that is protective of human health and the environment. The decontamination and demolition process is designed so that all disciplines are consulted and have input from the initiation of a project. The committee consists of all essential Environmental, Safety and Health (ES and H) and Facilities disciplines. The interdisciplinary-team approach has provided a mechanism that verifies adequate building and site assessment activities are conducted. This approach ensures that wastes generated during decontamination and demolition activities are handled and disposed according to Department of Energy (DOE), Federal, state, and local requirements. Because of the comprehensive nature of the SNL decontamination and demolition process, the strategy can be followed for demolition, renovation and new construction projects, regardless of funding source. An overview of the SNL/NM decontamination and demolition process is presented through a case study which demonstrates the practical importance of the formal process

K-25 Structural Separation and Demolition

International Nuclear Information System (INIS)

Cater, Frank

2008-01-01

The K-25 building is a former gaseous diffusion plant, built in 1944-1945 as part of the United States Manhattan Project. The structure was the largest structure under one roof, surpassed only by the Pentagon. Together the three wings represent about 17.8 hectare (44 acres) under roof and are generally about 18.3 meters (60 ft.) high on the outside face and approximately 12.2 meters (40 ft.) high on the inside face. The entire structure was built in the shape of a 'U', with a lateral distance of approximately one mile. It was constructed in individual building units with each unit connected using expansion joint-type connection. A single unit is approximately 24.4 meters (80 ft.) across and 122 meters (400 ft.) deep. The northern structure is connected to the eastern and western structures at the upper level floors. The four-level, U-shaped building is a steel-frame structure with corrugated cement-asbestos siding. The cell level is an elevated concrete structure supported by reinforced concrete columns located in the basement, or vault area. The vault area can be accessed at grade level from the outside perimeter. Inside the courtyard, the grade level has been raised to provide entry to the second or cell floor level. An engineering evaluation of the structure was performed to determine the condition of the structure and possibility of unplanned collapse of any portion of the structure. The evaluation included physical inspections, calculations for wind, pre-demolition loads, and evaluation of failure modes. The results of the evaluation have provided guidance for the demolition plan and the development of criteria for protection of personnel performing pre-demolition activities. Challenges include degradation of the structure that necessitated repair, dealing with changes in the code revisions from both the American Concrete Institute (ACI) and the American Institute of Steel Construction (AISC), access to areas of the structure that were not necessarily designed

2014-06-01

More than 1 million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with two PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost effectively implement with their own staffs in the normal course of housing operations when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing and measures that improve equipment efficiency. ARIES documented implementation 10 ten housing units. Total source energy consumption savings was estimated at 6%-10% based on BEopt modeling with a simple payback of 1.7 to 2.2 years. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

Ruzica Bozovic Stamenovic

2012-10-01

Full Text Available This paper examines emerging issues regarding Singapore public housing. With over 80 % of rapidly ageing population living in public housing the elderly perspective is of paramount importance for future development. Following a brief introduction of Housing and Development Board HDB 2 model we are examining new ideas occurring in different scopes and scales, from apartment to urban environment level. Issues like ageing in place, dignity, salutogenesis, active and independent life, image and identification, and other themes pertinent to old age are revisited. Recent issues like high-rise/high-density, consumerism and branding suggest that the usual dogmatic approach to elderly in public housing could be converted to result in creative, affordable, profitable and integrative public housing design.

THE EFFECT OF VESSEL SUPPLY ON SHIP-DEMOLITION PRICES

Directory of Open Access Journals (Sweden)

Nikos Kagkarakis

2017-02-01

Full Text Available The ship-demolition is one of the four main markets that form the shipping industry and plays an important role on the seaborne trade, as it mitigates imbalances between supply and demand for transportation services by adjusting the merchant fleet supply. The aim of this study is to examine whether the factors that determine the supply of vessels for demolition are capable of affecting materially the ship-demolition price formation. The availability of ships for demolition is primarily a function of the fleet’s age and the conditions on the freight and secondhand markets. The analysis is conducted on the crude tanker and the bulk carrier segments and the vector autoregressive model methodology is employed, whereby the effect of both the supply and the demand factors on the ship-demolition prices is examined. The results indicate that the supply side has limited effect on the price formation in the industry, which is driven by the demand for the steel-scrap commodity.

A review of UK housing policy: ideology and public health.

Science.gov (United States)

Stewart, J

2005-06-01

The aim of this paper is to review UK public health policy, with a specific reference to housing as a key health determinant, since its inception in the Victorian era to contemporary times. This paper reviews the role of social and private housing policy in the development of the UK public health movement, tracing its initial medical routes through to the current socio-economic model of public health. The paper establishes five distinct ideologically and philosophically driven eras, placing public health and housing within liberal (Victorian era), state interventionist (post World War 1; post World War 2), neoliberal (post 1979) and "Third Way" (post 1997) models, showing the political perspective of policy interventions and overviewing their impact on public health. The paper particularly focuses on the contemporary model of public health since the Acheson Report, and how its recommendations have found their way into policy, also the impact on housing practice. Public health is closely related to political ideology, whether driven by the State, individual or partnership arrangements. The current political system, the Third Way, seeks to promote a sustainable "social contract" between citizens and the State, public, private and voluntary organizations in delivering community-based change in areas where health inequalities can be most progressively and successfully addressed.

Winandari, M. I. R.

2018-01-01

Public open space in housing estates plays an important role particularly in disaster mitigation. In some housing, there are indications of shape and use of space changes post-handover to local government. The aim of this study is to explore the relationship between public open space condition and management related to disaster mitigation in Tangerang housing estates. Multiple case study method is used to analyse of 2 housing cases. Aspects of access and boundaries were used to evaluate the cases. The results showed that gated community housing type should have more than 1 access to facilitate evacuation by considering the farthest unit to the housing gate. This is necessary to provide open spaces that are easily accessible from all units as the first evacuation site during and post disaster.

Demolition Range Noise Abatement Technique Demonstration and Evaluation for the McAlester Army Ammunition Plant; TOPICAL

International Nuclear Information System (INIS)

CALDERONE, JAMES J.; GARBIN H, DOUGLAS

2001-01-01

Public concern regarding the effects of noise generated by the detonation of excess and obsolete explosive munitions at U.S. Army demolition ranges is a continuing issue for the Army's demilitarization and disposal groups. Recent concerns of citizens living near the McAlester Army Ammunition Plant (MCAAP) in Oklahoma have lead the U.S. Army Defense Ammunition Center (DAC) to conduct a demonstration and evaluation of noise abatement techniques that could be applied to the MCAAP demolition range. With the support of the DAC, MCAAP, and Sandia National Laboratories (SNL), three types of noise abatement techniques were applied: aqueous foams, overburden (using combinations of sand beds and dirt coverings), and rubber or steel blast mats. Eight test configurations were studied and twenty-four experiments were conducted on the MCAAP demolition range in July of 2000. Instrumentation and data acquisition systems were fielded for the collection of near-field blast pressures, far-field acoustic pressures, plant boundary seismic signals, and demolition range meteorological conditions. The resulting data has been analyzed and reported, and a ranking of each technique's effects has been provided to the DAC

Construction and demolition waste indicators.

The construction industry is one of the biggest and most active sectors of the European Union (EU), consuming more raw materials and energy than any other economic activity. Furthermore, construction waste is the commonest waste produced in the EU. Current EU legislation sets out to implement construction and demolition waste (CDW) prevention and recycling measures. However it lacks tools to accelerate the development of a sector as bound by tradition as the building industry. The main objective of the present study was to determine indicators to estimate the amount of CDW generated on site both globally and by waste stream. CDW generation was estimated for six specific sectors: new residential construction, new non-residential construction, residential demolition, non-residential demolition, residential refurbishment, and non-residential refurbishment. The data needed to develop the indicators was collected through an exhaustive survey of previous international studies. The indicators determined suggest that the average composition of waste generated on site is mostly concrete and ceramic materials. Specifically for new residential and new non-residential construction the production of concrete waste in buildings with a reinforced concrete structure lies between 17.8 and 32.9 kg m(-2) and between 18.3 and 40.1 kg m(-2), respectively. For the residential and non-residential demolition sectors the production of this waste stream in buildings with a reinforced concrete structure varies from 492 to 840 kg m(-2) and from 401 to 768 kg/m(-2), respectively. For the residential and non-residential refurbishment sectors the production of concrete waste in buildings lies between 18.9 and 45.9 kg/m(-2) and between 18.9 and 191.2 kg/m(-2), respectively.

Public housing renewal and social determinants of health.

Science.gov (United States)

Arthurson, Kathy; Levin, Iris; Ziersch, Anna

2016-01-01

This article draws on the concept of residential context of housing and its relationship to health. It considers a bundle of changes through implementation of a housing renewal initiative as part of the Carlton Housing Estate Upgrading Project in Melbourne, Australia. Beyond the quality and appropriateness of the housing, pertinent factors explored include social networks, safety and security, and green open space. Data collection for the research project included in-depth interviews with public housing tenants, private residents, and service providers who live on and service the estate, as well as neighborhood observations and participation in on-site events. A key finding was that the relational processes of how tenants were related to by others-specifically, the way housing was reallocated during the processes of renewal-affected social housing tenants' self-perceived health and well-being.

Estimation of construction and demolition waste using waste generation rates in Chennai, India.

Science.gov (United States)

Ram, V G; Kalidindi, Satyanarayana N

2017-06-01

A large amount of construction and demolition waste is being generated owing to rapid urbanisation in Indian cities. A reliable estimate of construction and demolition waste generation is essential to create awareness about this stream of solid waste among the government bodies in India. However, the required data to estimate construction and demolition waste generation in India are unavailable or not explicitly documented. This study proposed an approach to estimate construction and demolition waste generation using waste generation rates and demonstrated it by estimating construction and demolition waste generation in Chennai city. The demolition waste generation rates of primary materials were determined through regression analysis using waste generation data from 45 case studies. Materials, such as wood, electrical wires, doors, windows and reinforcement steel, were found to be salvaged and sold on the secondary market. Concrete and masonry debris were dumped in either landfills or unauthorised places. The total quantity of construction and demolition debris generated in Chennai city in 2013 was estimated to be 1.14 million tonnes. The proportion of masonry debris was found to be 76% of the total quantity of demolition debris. Construction and demolition debris forms about 36% of the total solid waste generated in Chennai city. A gross underestimation of construction and demolition waste generation in some earlier studies in India has also been shown. The methodology proposed could be utilised by government bodies, policymakers and researchers to generate reliable estimates of construction and demolition waste in other developing countries facing similar challenges of limited data availability.

Leveraging energy efficiency to finance public-private social housing projects

International Nuclear Information System (INIS)

Copiello, Sergio

2016-01-01

The Italian housing model relies on a high rate of privately owned houses. In comparison, few dwellings are built and managed by the public sector. The social housing stock has been built mainly during some post-second world war decades; instead, since the early nineties, it underwent a privatization process. Such a model is inefficient and iniquitous in the long run. Therefore, after being disregarded for several years, social housing has gone back to be among the main agenda items. Nonetheless, due to the lack of public grants, new funding sources are required. The government now fosters an increasing involvement of private finance through Public-Private Partnership schemes. A first outcome can be found in some pioneering experiences. Their comparative analysis allows bringing out worthwhile findings, which are useful to steer housing policies. Moderate to low yields entail the need to involve new kinds of private entities, particularly those adopting a venture philanthropy approach. Meanwhile, building energy performance measures are a crucial driver of feasibility. They allow the tenants to be willing to pay agreed rents somehow higher than both social rents of protected tenancies and fair rents of regulated tenancies. - Highlights: •In Italy, the provision of affordable dwellings was disregarded for years. •Recently, instead, social housing has come back to be among the main agenda items. •Latest regulations try to tie together social housing and Public-Private Partnership. •Social tenants may be asked to pay more than in protected and regulated tenancies. •Energy-efficient measures allow keeping the tenants neutral about the rent increase.

The electric heating method is, on the other hand, a demolition technique of unique concept since it adopts the bars to help the demolition of reinforced concrete structures. This technique has the following advantages for demolition: 1) the more densely a structure is reinforced with bars, the greater is the effect of the electric heating, 2) demolition after heating produces little dust, and 3) electric heating of reinforcing bars causes no damage to the portions of concrete not subjected to electric current. The present paper describes the procedures and results of a series of experiments we conducted to verify the efficiency of the electric heating method. In this method, a low-voltage high-current is run through reinforcing bars existing in a concrete structure, inducing intense heat in the bars which in its turn brings about cracks in the surrounding concrete mass, facilitating secondary demolition by hammer picks or other means. The experiments were performed on full-scale biological shield wall mock-ups of a BWR and a small nuclear reactor. The experiments revealed that these excellent features of the electric heating method are worth utilizing in stripping demolition of radioactivated regions of biological shield walls in nuclear power plants. The electric heating method is currently being adopted and shows effective results in partial demolition works in diaphragm wall shafts where starting/arriving holes are to be fixed for shield machines without damaging surrounding portions.

Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16% and duct leakage reductions averaged 23%. Total source energy consumption savings due to implemented measures was estimated at 3-10% based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing and measures that improve equipment efficiency. ARIES documented implementation in ten housing units. Reductions in average air leakage were 16-20% and duct leakage reductions averaged 38%. Total source energy consumption savings was estimated at 6-10% based on BEopt modeling with a simple payback of 1.7 to 2.2 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of unit per year nationally.

2001-01-01

To determine frequency of and possible associations between environmental housing factors and self-reported respiratory symptoms in public housing. We used a community-participatory method in which trained residents conducted in-person interviews with a random sample of 53 households in one housing development in Boston, Massachusetts. Environmental factors suspected of affecting respiratory health that were reported by more than 30 percent of respondents included: Moisture (43 percent), mold (43 percent), cracks in walls, floors and ceilings (49 percent), sewage leaks (33 percent), unexplained odor (35 percent), use of air fresheners (91 percent), use of gas ovens for heating (38 percent), no vent for the oven (74 percent), stuffy air (66 percent), overheating at least part of the winter (73 percent), cockroaches (70 percent), rodents (40 percent), pets (39 percent), frequent renovations (40 percent), repeated requests for repairs (52 percent), dust from construction (45 percent), use of more than three hazardous household products (32 percent), vehicle traffic nearby (81 percent), and smoking in the household (57 percent). Forty percent of respondents reported having asthma. Respondents also reported that 56 percent of their children had asthma. Forty percent of respondents reported wheeze and 48 percent reported coughing or sneezing episodes in the preceding month. We found the following positive statistically significant associations, adjusted for age, sex, Black or Hispanic origin, and years lived in public housing: wheeze with moisture problems (OR = 4.8; CI = 1.2, 19.3), sewage leaks (OR = 6.3; CI = 1.3, 30.3), odor (OR = 7.5; CI = 1 .4, 39.0), cracks in walls,floors and ceilings (OR = 8.6; CI 1.9, 38.0), and frequency of renovations (OR = 9.8; CI = 1.8, 54.4); cough with moisture problems (OR = 5.3; CI = 1.3, 20.8), stuffy air (OR = 4.4; CI = 1.2, 16.7), cockroaches (OR = 5.4; CI = 1.2, 24.2), smoking (OR = 5.0; CI = 1.2, 20.5), odor (OR = 10.9; CI = 2

Contested visions of American democracy: citizenship, public housing, and the international arena.

Science.gov (United States)

Argersinger, Jo Ann E

2010-01-01

This essay reexamines the history of public housing and the controversy it generated from the Great Depression to the Cold War. By recasting that history in the global arena, it demonstrates that the debate over public housing versus homeownership was also a debate over the meaning of American citizenship and democracy, pointing up starkly divergent notions about what was and was not American. Through an examination of national conflicts and neglected local struggles, this article further shows that the fight over public housing was far more meaningful and volatile than traditionally assumed. Both critics and advocates of public housing drew from international experiences and imagery in positioning the home as a constitutive feature of citizenship in American democracy. Fears of Bolshevism, fascism, and communism served to internationalize issues of race, space, and housing and together shaped the decision of whether a decent home was an American right or privilege.

Phantom Housing: The Rise and Fall of Public Housing in North America

Benjamin Gianni

2012-11-01

Full Text Available This paper examines the rise and fall of public housing in North America in order to explore the principle of sustainability. By extension, it addresses the concept of sustainability as it relates to the city. Urbanity is simultaneously the most and least sustainable form of development. While extremely sustainable from the point of view of density (economies of scale, efficient use ofinfrastructure, etc., it is highly vulnerable to social, political and economic forces. Such forces can easily trump the environmental sustainability of any building or community.The death and transfiguration of key portions of our public housing stock provides insights into this phenomenon – for which I will use Toronto’s Regent Park as a case study. The redevelopment ofthis 69-acre parcel aims to transform a failed social vision into a model for sustainable community development.

2012-03-01

Full Text Available The ongoing crisis in the housing services and public utilities sphere determines the need to accelerate its integration into the market space. The author proposes to apply the cluster initiatives, which, in his opinion, provide the solution of housing services and public utilities problems in terms of their broader vision. This paper attempts to highlight the benefits of the cluster approach to the development of housing services and public utilities, and identifies the main provisions in the process of its implementation. The essence of the concept of «housing services and social cluster of the region» in terms of housing services and public utilities development is revealed, members of cluster unification are designated, its components are identified, the purpose of introducing the cluster model of housing services and public utilities reform management is determined, which essence is to change the mentality of the producers and consumers of housing services and public utilities in the direction of increasing responsibilities and respect for mutual interests in the market of housing services and public utilities. The main provisions and principles of formation of housing services and social cluster of the region are reviewed, as well as the characteristics and trends of its development. An authorial approach to the development of a strategy of forming a housing services and social cluster in the region in accordance with modern trends is presented. The leading role of several factors in establishing the basic prerequisites for sustainable operation of housing services and social cluster of the region is justified. These factors include governmental regulation of pricing and forms of support to small entrepreneurship development, creation of financial security system, development of public-private partnerships and implementation of innovative technologies. The role of non-governmental organizations and public associations in the formation of

Use of rubble from building demolition in mortars.

Corinaldesi, V; Giuggiolini, M; Moriconi, G

2002-01-01

Because of increasing waste production and public concerns about the environment, it is desirable to recycle materials from building demolition. If suitably selected, ground, cleaned and sieved in appropriate industrial crushing plants, these materials can be profitably used in concrete. Nevertheless, the presence of masonry instead of concrete rubble is particularly detrimental to the mechanical performance and durability of recycled-aggregate concrete and the same negative effect is detectable when natural sand is replaced by fine recycled aggregate fraction. An alternative use of both masonry rubble and fine recycled material fraction could be in mortars. These could contain either recycled instead of natural sand or powder obtained by bricks crushing as partial cement substitution. In particular, attention is focused on the modification that takes place when either polypropylene or stainless steel fibers are added to these mortars. Polypropylene fibers are added in order to reduce shrinkage of mortars, stainless steel fibers for improving their flexural strength. The combined use of polypropylene fibers and fine recycled material from building demolition could allow the preparation of mortars showing good performance, in particular when coupled with bricks. Furthermore, the combined use of stainless steel fibers and mortars containing brick powder seems to be an effective way to guarantee a high flexural strength.

Housing in China: State Governance, Market and Public Perception

Directory of Open Access Journals (Sweden)

Emile Kok-Kheng Yeoh

2017-04-01

Full Text Available Chinese house prices have been receiving huge coverage in both the domestic and the international media. Although the Chinese government has implemented many policies to control house prices, especially in the big cities, it is obvious that there is disequilibrium between demand for and supply of houses. Even though numerous housing policies have been put in place to overcome that, house prices in China are still rising. Many Chinese citizens from the low- and middle-incomes group find it difficult to purchase a house in the cities due to high house prices. This paper covers the current situation of the house prices in China, introduces the existing state of affairs about the Chinese housing market, explores a series of important reasons for high house prices, examines various public policies the Chinese government is using to control real estate, as well as reveals the citizens’ perceptions related to rising house prices. To gauge citizens’ perception of the current state of affairs in this regard, a questionnaire survey was conducted to gather information with a final sample of 256 respondents from more than ten cities of different tiers in the different regions of China.

Housing, Urban Renewal and Socio-Spatial Integration. A Study on Rehabilitating the Former Socialistic Public Housing Areas in Beijing

Directory of Open Access Journals (Sweden)

Xiaoxi Hui

2017-11-01

Full Text Available The initiative of this study derived from my concern of two critical urban issues in China today: housing and urban renewal. In the recent two decades, the Chinese urban housing stock underwent a significant, if not extreme, transformation. From 1949 to 1998, the urban housing stock in China largely depended on the public sector, and a large amount of public housing areas were developed under the socialistic public housing system in Beijing and other Chinese cities. Yet in 1998, a radical housing reform stopped this housing system. Thus, most of the public housing stock was privatized and the urban housing provision was conferred to the market. The radical housing privatization and marketization did not really resolve but intensified the housing problem. Along with the high-speed urbanization, the alienated, capitalized and speculative housing stock caused a series of social and spatial problems. The Chinese government therefore attempted to reestablish the social housing system in 2007. However, the unbalanced structure of the Chinese urban housing stock has not been considerably optimized and the housing problem is still one of the most critical challenges in China. Based on the background of privatization, the former socialistic public housing areas in Beijing confront the ambiguity of their housing stock and the confusion of housing management. While they still accommodate the majority of urban residents and are identified by their good places, (social and programmatic mixed communities, vibrant local life, and diversified housing types, they are facing the serious challenges of physical deterioration and social decline. Therefore, urban renewal was thought as an effective solution seeking to improve the living conditions in those neighborhoods. Nevertheless, urban renewal in itself is also a controversial issue. In order to solve the housing problem, the large-scale urban renewal in Beijing started at the beginning of the 1990s. The radical

Eccentric housing finance sources by the urban poor in Zimbabwe: case of Cowdray Park low-income self help housing scheme in Bulawayo

Directory of Open Access Journals (Sweden)

Trynos GUMBO

2010-06-01

Full Text Available Zimbabwe has a sombre housing crisis in all its urban centres. All attempts by the government to vary housing delivery systems to ameliorate the problem have proved futile as the backlog it inherited from the colonial masters continues to soar. The situation has however been exacerbated by 2005 demolitions and evictions in the country’s major cities that destroyed homes and businesses leaving the majority of the poor and disadvantaged segments of society in deeper poverty, deprivation and destitution. The main challenge to housing the urban poor is housing finance. Public funds are meagre and private funds are not accessible to the poor due to lack of collateral security and inability to service the loans. Fascinatingly, the poor’s income comes from informal sector activities that absorbs a large percentage of the labour force and keeps the economy going while the large modern enterprises continue to reel under the economic downturn. Unfortunately the Zimbabwean informal sector has generally been perceived as a nuisance, a haven for criminals and a menace. Evidence shows that there is a strong relationship between the urban poor’s housing finance, informal sector activities and self-help housing strategies in Zimbabwe. In the pre-2005 Operation Murambatsvina era, the poor were making some construction progress as evidenced by the structures that had developed. This paper calls for active support and facilitation of the poor’s sources of income, and advocates for the involvement of other players such as the private sector and the international community in housing the poor. The Zimbabwe government’s plan to house the homeless and poor on its 250 000 stands countrywide through self-help programmes can only be successful if their sources of income are promoted and facilitated.

Environmental impacts of manufactured gas plant demolition: examples from site remediation experience

Energy Technology Data Exchange (ETDEWEB)

Unites, D. [Atlantic Environmental Services, Inc., Colchester, CT (United States)

1995-12-31

Inappropriate demolition of manufactured gas plant (MGP) sites may leave a continuing legacy in the environmental record. Much of the contamination encountered at former gas plants originated from on-site disposal or from spills and leaks during operations. However, some of the greatest potential for continual release comes from inappropriately decommissioned vessels and tanks. These structures contained liquids such as tars, oils, water, and other fluids associated with by-product removal or the gas stream purification process. Inorganic `solids` constitute another, although generally minor, source of contaminants during demolition. These contaminants include: cyanide- and sulfide-containing purifier materials; asbestos from roofing, pipe lagging, etc.; mercury from controls and manometers; and lead from painted surfaces. Normal elements of decommissioning and dismantling include: purging the piping system with inert gas; removal and sale of liquids having commercial value; disposal or abandonment of non-saleable liquids; scrapping and dismantling of above-grade metal vessels; abandonment of below-grade vessels; and demolition of above-grade buildings. Depending on the time from the cessation of operations to the demolition, some steps may have been omitted. Appropriate demolition would also take into account removal and disposal of asbestos, cyanide, lead, and mercury-containing materials prior to razing structures. By employing precautions during demolition, widespread contamination can be avoided and subsequent reuse of the site can be facilitated.

, economical and cost-effective approach that embodies key physical principles that minimize MEOSI dose and therefore maximize public safety. The option also has residual contamination fixed in place, reduced dose through the use of selected floor and vessel grouting, and equipment and wall slab concurrent removals including the use of machines instead of people to maximize worker safety. A separate life-cycle cost comparison demonstrates that the Inside-Out Demolition is less costly than a traditional 3-step demolition approach establishing it as cost effective and economic. Equipment and wall slab concurrent removals and the ability to reduce waste volumes are expected to further enhance the cost effective and economic nature of this option. The Inside-Out Demolition is demonstrably (through modeling) feasible and practical using standard industry techniques and technology. The Inside-Out Demolition allows DOE considerable waste management flexibility (waste volume and classification) inherent in the slab cutting and removal approach for walls, floors and ceilings for waste disposal cost optimization decision-making when the waste is generated taking into account receiver site options available to DOE at the time. There is no supporting documentation to indicate that cost-effective decontamination of gamma radiation contaminated surfaces such as those in the MPPB can be achieved. It is concluded that the traditional approaches that have relied on contact-handled decontamination operations (as precedents) for reducing the residual contamination inventory prior to demolition will not be practical or cost effective for demolition of the MPPB. As such, it is further concluded that the Inside-Out Demolition approach will be not only cost effective but also the only feasible practical approach for MPPB Demolition. The Inside-Out Demolition approach overcomes the high technical, cost and schedule risks associated with achieving high cleanliness objectives for the traditional 3-step

Effect of Co-Composting Cattle Manure with Construction and Demolition Waste on the Archaeal, Bacterial, and Fungal Microbiota, and on Antimicrobial Resistance Determinants.

Agricultural operations generate large quantities of manure which must be eliminated in a manner that is consistent with public health guidelines. Meanwhile, construction and demolition waste makes up about 25% of total solid municipal waste. Co-composting of manure with construction and demolition waste offers a potential means to make manure safe for soil amendment and also divert construction and demolition waste from municipal landfills. Therefore, the archaeal, bacterial, and fungal microbiota of two different types of composted cattle manure and one co-composted with construction and demolition waste, were assessed over a 99-day composting period. The microbiota of the three compost mixtures did not differ, but significant changes over time and by sampling depth were observed. Bacillus and Halocella, however, were more relatively abundant in composted manure from cattle fed dried distillers' grains and solubles. Proteobacteria and Bacteroidetes were enriched at day 0 and Firmicutes at day 99. The fungal genus Kernia was the most relatively abundant overall and was enriched at day 0. The concentration of 12 antimicrobial resistance determinants in the compost mixtures was also determined, and 10 of these determinants decreased significantly from days 0 to 99. The addition of construction and demolition waste did not affect the persistence of antimicrobial resistance genes or community structure of the compost microbiota and therefore co-composting construction and demolition waste with cattle manure offers a safe, viable way to divert this waste from landfills.

Project Selection and Transparency Factors in Housing Public-Private Partnerships in Nigeria

Directory of Open Access Journals (Sweden)

Eziyi Offia Ibem

2018-06-01

Full Text Available The application of Public-Private Partners (PPPs in housing provisioning is on the increase across the world. However, there is a paucity of empirical studies on the specific factors considered at the initiation, and measures taken to ensure transparency at the procurement stages, of PPP housing projects. This study examined project selection factors and transparency measures in PPP housing projects using data sourced from oral interviews with 27 experts in nine PPP housing schemes in Nigeria. Results of the content analysis revealed that the top two selection factors considered by both the public and private sector operators of PPP housing projects in Nigeria are the availability of land and viability of the funding arrangements. Whereas the public-sector partners also consider the availability of competent private sector to deliver the projects, the private developers are concerned with the location of proposed projects. It was also found that the two key measures taken to ensure transparency at the procurement stage of the projects are transparent and competitive bidding and open advertisements of tender opportunities. These imply that before embarking on PPP housing projects, operators should ensure that there is available land in good locations, sound funding arrangements, and measures for achieving transparency in the schemes.

This study sought to examine whether: (1) the health composition of the social networks of children living in subsidized housing within market rate developments (among higher-income neighbors) differs from the social network composition of children living in public housing developments (among lower-income neighbors); and (2) children's social network composition is associated with children's own health. We found no significant differences in the health characteristics of the social networks of children living in these different types of public housing. However, social network composition was significantly associated with several aspects of children's own health, suggesting the potential importance of social networks for the health of vulnerable populations.

Decommissioning and demolition in the European Union. Current status

International Nuclear Information System (INIS)

Blohm-Hieber, Ute

2009-01-01

The European Commission pursues the environmental and energy policy goals of limiting global warming to a maximum of 2 C and, therefore, reducing CO 2 emissions by at least 20%. Nuclear power, with its present 30% contribution to the Community's electricity supply and the low CO 2 emissions of the entire fuel cycle, makes an important contribution to an energy mix matching the 3 factors of competitiveness, security of supply, and sustainability. The decision to use nuclear power plants in their respective countries for electricity production is left to each member state. As of mid-2008, 146 nuclear power plants were in operation in the European Union, while 74 had been shut down permanently. Two nuclear power plants had been demolished completely, showing that the European Community is just at the beginning of the learning curve in this field. The importance of nuclear power plant decommissioning and demolition will increase in the future as replacement capacity in nuclear power generation will become necessary. The European Commission's activities in decommissioning and demolition date from the 1990s: The provisions about environmental impact assessment and the recommendations to apply Article 37 (potential impacts on water, soil and air) of the Euratom Treaty demand a description of decommissioning and demolition of nuclear power plants. In a ruling of 2002, the European Court of Justice assigns to the Community the required competences in the fields of nuclear safety and, consequently, also decommissioning and demolition. The financial provisions necessary for these activities are covered in the Electricity Directive within the framework of the rules for a common single market in 2003. After a first status report, the Commission published recommendations about financing decommissioning and demolition in 2006. (orig.)

Hanford Patrol Academy Demolition Sites Closure Plan

International Nuclear Information System (INIS)

1992-11-01

From 1975 to 1991 the Hanford Patrol Academy Demolition Sites (HPADS) were used for demolition events. These demolition events were a form of thermal treatment for spent or abandoned chemical waste. Because the HPADS will no longer be used for this thermal activity, the sites will be closed. Closure will be conducted pursuant to the requirements of the Washington State Department of Ecology (Ecology) Dangerous Waste Regulations, Washington Administrative Code (WAC) 173-303-610 and 40 CFR 270.1. Closure also will satisfy closure requirements of WAC 173-303-680 and for the thermal treatment closure requirements of 40 CFR 265.381. This closure plan presents a description of the HPADS, the history of the waste treated, and the approach that will be followed to close the HPADS. Because dangerous waste does not include the source, special nuclear, and by-product material components of mixed waste, radionuclides are not within the scope of WAC 173-303 or of this closure plan. The information on radionuclides is provided only for general knowledge where appropriate. Only dangerous constituents derived from HPADS operations will be addressed in this closure plan in accordance with WAC 173-303-610(2)(b)(i). The HPADS are actually two distinct soil closure areas within the Hanford Patrol Academy training area

Final report on implementation of energy conservation practices training in selected public housing developments

Energy Technology Data Exchange (ETDEWEB)

1991-10-01

This report on the implementation of energy conservation practices training in selected public housing developments represents an initiative of the Research and Education Division, Office of Minority Economic Impact, US Department of Energy. The Office of Minority Economic Impact (MI) was created by Congress in 1979, within the US Department of Energy, to afford the Secretary advice on the effect policies, regulations and other actions of DOE respecting minority participation in energy programs. The Director of MI is responsible for the conduct of ongoing research into the effects, including socio-economic and environmental, of national energy programs, policies, and regulations of the Department of minorities. Public housing in the United States is dominated by minorities, public housing is a large consumer of residential energy. Consequently, this project is a logical merging of these two factors and an attempt to somehow influence energy savings through improving public housing residents` energy-consumption practices. This final report attempts to capture the results of this current demonstration, and incorporate the historical basis for today`s results by renewing the efforts that preceded the implementation of energy conservation practices training in selected public housing developments.

Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information on sow housing. For example, initially 30.4% of respondents indicated that they supported the use of gestation stalls; this declined to 17.8% after participants were provided additional information. Qualitative analysis of comments showed that supporters of gestation stalls expressed concern about the spread of disease and aggression between animals in less confined systems, whereas supporters of group housing placed more emphasis on the sow's ability to interact socially and perform natural behaviors. These results point to public opposition to the use of gestation stalls, and indicate that the more that the public learns about gestation stalls the less willing they will be to accept their use.

Choosing a sustainable demolition waste management strategy using multicriteria decision analysis

Roussat, Nicolas; Dujet, Christiane; Mehu, Jacques

2009-01-01

This paper presents an application of the ELECTRE III decision-aid method in the context of choosing a sustainable demolition waste management strategy for a case study in the city of Lyon, France. This choice of waste management strategy takes into consideration the sustainable development objectives, i.e. economic aspects, environmental consequences, and social issues. Nine alternatives for demolition waste management were compared with the aid of eight criteria, taking into account energy consumption, depletion of abiotic resources, global warming, dispersion of dangerous substances in the environment, economic activity, employment, and quality of life of the local population. The case study concerned the demolition of 25 buildings of an old military camp. Each alternative was illustrated with different waste treatments, such as material recovery, recycling, landfilling, and energy recovery. The recommended solution for sustainable demolition waste management for the case study is a selective deconstruction of each building with local material recovery in road engineering of inert wastes, local energy recovery of wood wastes, and specific treatments for hazardous wastes

Influence of construction and demolition waste management on the environmental impact of buildings

International Nuclear Information System (INIS)

Coelho, André; Brito, Jorge de

2012-01-01

Highlights: ► Environmental impacts of different demolition practices. ► “Top-down” approach to the Life Cycle Analysis methodology. ► Results based on real buildings measurements and demolition contractor activities. ► Not every type of selective demolition brings about environmental benefits. - Abstract: The purpose of this study is to quantify comparable environmental impacts within a Life Cycle Analysis (LCA) perspective, for buildings in which the first (Materials) and last (End of Life) life cycle stages are adjusted to several waste/material management options. Unlike most LCAs, the approach is “top-down” rather than “bottom-up”, which usually involves large amounts of data and the use of specific software applications. This approach is considered appropriate for a limited but expedient LCA designed to compare the environmental impacts of different life cycle options. Present results, based on real buildings measurements and demolition contractor activities, show that shallow, superficial, selective demolition may not result in reduced environmental impacts. Calculations actually show an increase (generally less than 5%) in most impact categories for the Materials and End of Life stages because of extra transportation needs. However, core material separation in demolition operations and its recycling and/or reuse does bring environmental benefits. A reduction of around 77% has been estimated in the climate change impact category, 57% in acidification potential and 81% in the summer smog impact (for the life cycle stages referred).

The Effects of Data Collection Method and Monitoring of Workers’ Behavior on the Generation of Demolition Waste

Directory of Open Access Journals (Sweden)

Gi-Wook Cha

2017-10-01

Full Text Available The roles of both the data collection method (including proper classification and the behavior of workers on the generation of demolition waste (DW are important. By analyzing the effect of the data collection method used to estimate DW, and by investigating how workers’ behavior can affect the total amount of DW generated during an actual demolition process, it was possible to identify strategies that could improve the prediction of DW. Therefore, this study surveyed demolition waste generation rates (DWGRs for different types of building by conducting on-site surveys immediately before demolition in order to collect adequate and reliable data. In addition, the effects of DW management strategies and of monitoring the behavior of workers on the actual generation of DW were analyzed. The results showed that when monitoring was implemented, the estimates of DW obtained from the DWGRs that were surveyed immediately before demolition and the actual quantities of DW reported by the demolition contractors had an error rate of 0.63% when the results were compared. Therefore, this study has shown that the proper data collection method (i.e., data were collected immediately before demolition applied in this paper and monitoring on the demolition site have a significant impact on waste generation.

OPERATIONAL LIMITATIONS FOR DEMOLITION OF A HIGHLY ALPHA CONTAMINATED BUILDING MODLES VERSUS MEASURED AIR & SURFACE ACTIVITY CONCENTRATIONS

Energy Technology Data Exchange (ETDEWEB)

LLOYD, E.R.

2006-11-02

The demolition of a facility historically used for processing and handling transuranic materials is considered. Residual alpha emitting radionuclide contamination poses an exposure hazard if released to the local environment during the demolition. The process of planning for the demolition of this highly alpha contaminated building, 232-Z, included a predemolition modeling analysis of potential exposures. Estimated emission rates were used as input to an air dispersion model to estimate frequencies of occurrence of peak air and surface exposures. Postdemolition modeling was also conducted, based on the actual demolition schedule and conditions. The modeling results indicated that downwind deposition is the main operational limitation for demolition of a highly alpha-contaminated building. During the demolition of 232-Z, airborne radiation and surface contamination were monitored. The resultant non-detect monitoring results indicate a significant level of conservatism in the modeled results. This comparison supports the use of more realistic assumption in the estimating emission rates. The resultant reduction in modeled levels of potential exposures has significant implications in terms of the projected costs of demolition of such structures.

2015-04-10

Public housing residents have a high risk of chronic disease, which may be related to neighborhood environmental factors. Our objective was to understand how public housing residents perceive that the social and built environments might influence their health and wellbeing. We conducted focus groups of residents from a low-income public housing community in Baltimore, MD to assess their perceptions of health and neighborhood attributes, resources, and social structure. Focus groups were audio-recorded and transcribed verbatim. Two investigators independently coded transcripts for thematic content using editing style analysis technique. Twenty-eight residents participated in six focus groups. All were African American and the majority were women. Most had lived in public housing for more than 5 years. We identified four themes: public housing's unhealthy physical environment limits health and wellbeing, the city environment limits opportunities for healthy lifestyle choices, lack of trust in relationships contributes to social isolation, and increased neighborhood social capital could improve wellbeing. Changes in housing and city policies might lead to improved environmental health conditions for public housing residents. Policymakers and researchers may consider promoting community cohesiveness to attempt to empower residents in facilitating neighborhood change.

Re-emergence of Indigeneity in transformed Layouts in Urban Public Housing in Nigeria

Directory of Open Access Journals (Sweden)

Abubakar Danladi Isah

2016-01-01

Full Text Available In contrast to the one whole homogenous configuration provided by developers that has often proved ineffective overtime, transformed public housing units are widespread in developing cities. Though transformation is a natural phenomenon of inhabitation, its various levels and degree can have implicit values. In recent times in Nigeria, heterogeneous spatial patterns of transformed houses in public housing estates has given empirical evidence of essentially inevitable reflection of culture sensitivity as hypothesized by previous studies. That hints that the mainstream sustainable values were probably ignored during design process. This study attempted to connect that possible missing link. To achieve that aim, it developed two objectives. First, is to identify core values behind space layouts in the mainstream. Then, to examine how they exist in the transformed layout as reflected at communal origins. It investigated on 42 transformed units in selected urban Public housings neighborhoods via a stratified conditional sampling conducted in five states of Nigeria. Qualitative methods were adopted for data analysis. After identifying the core ethnic groups in the region, their social indicators with regards to space use were determined through ethnographic principles. These indicators were then operationally defined, and used as a tool to examine users’ motivations in the transformation process in urban context. Spatial pattern analysis, by using gamma delineation, revealed the social content in the transformations after comparing initial design and the transformed spatial configurations. The outcome signified the mainstream cultural values in the transformation process hence in Public housing design. The convergence of mainstream values into urban transformed layouts suggested that they cannot be ignored during design process. The outcome of this research might be useful in designing sustainable public housings in culture sensitive environments

Changes to indoor air quality as a result of relocating families from slums to public housing

Burgos, Soledad; Ruiz, Pablo; Koifman, Rosalina

2013-05-01

One largely unstudied benefit of relocating families from slums to public housing is the potential improvement in indoor air quality (IAQ). We compared families that moved from slums to public housing with those that remained living in slums in Santiago, Chile in terms of fine particulate matter (PM2.5) as main indicator of change. A cross-sectional study of 98 relocated families and 71 still living in slums was carried out, obtaining indoor and outdoor samples by a Personal Environmental Monitor. Home characteristics, including indoor air pollution sources were collected through questionnaires. Multivariate regression models included the intervention (public housing or slum), indoor pollution sources, outdoor PM2.5 and family characteristics as predictors. Indoor PM2.5 concentrations were higher in slums (77.8 μg m-3 [SD = 35.7 μg m-3]) than in public housing (55.7 μg m-3 [SD = 34.6 μg m-3], p slum houses. The multivariate analysis showed that housing intervention significantly decreased indoor PM2.5 (10.4 μg m-3) after adjusting by the other predictors. Outdoor PM2.5 was the main predictor of indoor PM2.5. Other significant factors were water heating fuels and indoor smoking. Having infants 1-23 months was associated with a lowering of indoor PM2.5. Our results suggest that a public housing program that moves families from slums to public housing improves indoor air quality directly and also indirectly through air pollution sources.

2003-01-01

FRJ-2 (MERLIN), the swimming pool reactor cooled and moderated by light water, was built at the then Juelich Nuclear Research Establishment (KFA) between 1958 and 1962. In the period between 1964 and 1985, it was used for. The reactor was decommissioned in 1985. Since 1996, most of the demolition work has been carried out under the leadership of a project team. The complete secondary cooling system was removed by late 1998. After the cooling loops and experimental installations had been taken out, the reactor vessel internals were removed in 2000 after the water had been drained from the reactor vessel. After the competent authority had granted a license, demolition of the reactor block, the central part of the research reactor, was begun in October 2001. In a first step, the reactor operating floor and the reactor attachment structures were removed by the GNS/SNT consortium charged with overall planning and execution of the job. This phase gave rise to approx. The reactor block proper is dismantled in a number of steps. A variety of proven cutting techniques are used for this purpose. Demolition of the reactor block is to be completed in the first half of 2003. (orig.) [de

Progressively safer, cheaper demolition of Fernald

International Nuclear Information System (INIS)

Nichols, Robert; Pennington, Norman

2000-01-01

Fluor Fernald, Inc. has been progressively improving Decontamination and Dismantlement (D and D) at the Department of Energy's Fernald Environmental Management Project by applying new technologies and better methodologies to the work. Demolition issues existed in the past that necessitated new or improved solutions to maintain worker safety, protect the environment and accomplish the work in a cost effective manner. Lessons learned from D and D of 80 structures has led to a systematic approach, which can be implemented in various D and D arenas. When facility production was halted, hold-up material and process residues remained in the process piping and components. Over 500,000 pounds of material was removed by workers who completed the tasks two years ahead of schedule, $7 million under budget and with an excellent safety record. This success was the result of detailed planning and irdision of lessons learned as work progressed from facility to facility. Work sequences were developed that reduced airborne contamination. Demolition of structures has been performed at Fernald by carefully selected and qualified subcontractors. Asbestos and lead abatement, equipment, piping and conduit removal, and structural demolition have been completed to progressively higher performance specifications developed by Fluor Fernald based on lessons learned during execution. Safety continues to be the primary consideration in performing potentially hazardous work. Technologies such as hydraulic shears have been developed and used to keep workers away from danger. A new technology, ''Cool Suits,'' has been demonstrated to help prevent heat stress when anti-contamination clothing is required in elevated temperature working conditions. For tall structures, implosion technologies have been employed with progressively improved results, Several other new technologies have been evaluated by Fluor Fernald and applied by subcontractors. The improved technologies included the oxy-gas torch

Large quantities of construction and demolition (C&D) waste are generated in China every year, but their potential environmental impacts on the surrounding areas are rarely assessed. This study focuses on metals contained in C&D waste, characterizing the metal concentrations and their related environmental risks. C&D waste samples were collected in Shenzhen City, China, from building demolition sites, renovation areas undergoing refurbishment, landfill sites, and recycling companies (all located in Shenzhen city) that produce recycled aggregate, in order to identify pollution levels of the metals As, Cd, Cr, Cu, Pb, Ni, and Zn. The results showed that (1) the metal concentrations in most demolition and renovation waste samples were below the soil environmental quality standard for agricultural purposes (SQ-Agr.) in China; (2) Cd, Cu, and Zn led to relatively higher environmental risks than other metals, especially for Zn (DM5 tile sample, 360 mg/kg; R4 tile sample, 281 mg/kg); (3) non-inert C&D waste such as wall insulation and foamed plastic had high concentrations of As and Cd, so that these materials required special attention for sound waste management; and (4) C&D waste collected from landfill sites had higher concentrations of Cd and Cu than did waste collected from demolition and refurbishment sites.

2013-11-01

The significant amount of waste generated from construction demolition has become a chronic problem in many developing countries. Using data obtained from demolition contractors and various other sources, this paper proposes a framework for proper handling of construction demolition waste (CDW) to serve as a decision support tool in countries suffering from the lack of national CDW management guidelines. The framework is then demonstrated through a case study in the city of Beirut, Lebanon, and a sensitivity analysis is carried out to examine the economic feasibility of developing a recycling facility. The analysis showed that in order for a facility to be feasible, a gate fee should be charged in the presence of a market for recycled aggregates. The results confirm the significance of instigating and implementing legislation to control illegal dumping, constructing, and managing engineered landfills, and establishing markets for recycled CDW.

1986-12-01

This demonstration project studied how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilities indigenous business development where appropriate, and trains residents to provide needed services.

PROJECT EXPERIENCE REPORT DEMOLITION OF HANFORDS 233-S PLUTONIUM CONCENTRATION FACILITY

BERLIN, G.T.; ORGILL, T.K.

2004-01-01

This report provides a summary of the preparation, operations, innovative work practices, and lessons learned associated with demolition of the 2334 Plutonium Concentration Facility. This project represented the first open-air demolition of a highly-contaminated plutonium facility at the Hanford Site. This project may also represent the first plutonium facility in the US. Department of Energy (DOE) complex to have been demolished without first decontaminating surfaces to near ''free release'' standards. Demolition of plutonium contaminated structures, if not properly managed, can subject cleanup personnel and the environment to significant risk. However, with proper sequencing and innovative use of commercially available equipment, materials, and services, this project demonstrated that a plutonium processing facility can be demolished while avoiding the need to perform extensive decontamination or to construct large enclosures. This project utilized an excavator with concrete shears, diamond circular saws, water misting and fogging equipment, commercially available fixatives and dust suppressants, conventional mobile crane and rigging services, and near real-time modeling of meteorological and radiological conditions. Following a significant amount of preparation, actual demolition of the 233-S Facility began in October 2003 and was completed in late April 2004. The knowledge and experience gained on this project are important to the Hanford Site as additional plutonium processing facilities are scheduled for demolition in the near future. Other sites throughout the DOE Complex may also be faced with similar challenges. Numerous innovations and effective work practices were implemented on this project. Accordingly, a series of ''Lessons Learned and Innovative Practices Fact Sheets'' were developed and are included as an appendix to this report. This collection of fact sheets is not intended to capture every innovative work practice and lesson learned, but rather

The knowledge and experience gained on this project are important to the Hanford Site as additional plutonium processing facilities are scheduled for demolition in the near future. Other sites throughout the DOE Complex may also be faced with similar challenges. Numerous innovations and effective work practices were implemented on this project. Accordingly, a series of ''Lessons Learned and Innovative Practices Fact Sheets'' were developed and are included as an appendix to this report. This collection of fact sheets is not intended to capture every innovative work practice and lesson learned, but rather to

In-house training, formal education and public outreach

International Nuclear Information System (INIS)

Willis, Y.A.

1992-01-01

This paper assumes that a stronger national commitment to public education on nuclear energy and, most particularly radioactive waste management, it needed to overcome public resistance to nuclear projects. Effective public education must become the superordinate goal uniting industry, government, professional societies, national laboratories and the educational community. Since instruction is labor intensive, we must search for more cost effective ways of achieving results. Therefore, this paper proposes: Collaborative training and educational strategies involving as many of the stakeholders as possible; and Innovative tools to improve the credibility, quality and cost effectiveness of education. This win-win approach can reduce the collective expenditures through cost-sharing, as well as the sharing of resources and products. It can close gaps in both in-house training and formal education. Finally, in public outreach, the joint approach addresses the politics of sponsorship by providing checks and balances, and thus improving credibility and public acceptance

Thermal resistance and conductivity of recycled construction and demolition waste (RCDW concrete blocks

Directory of Open Access Journals (Sweden)

Ivan Julio Apolonio Callejas

Full Text Available Abstract In Brazil, studies to reuse construction and demolition waste are a special issue because a large amount of this material has been delivered to the public landfills and in illegal places. Some researchers have suggested reusing this material in building elements, such as bricks or blocks. It is possible to find a lot of researches in physical/mechanical characterization, while little effort has been made to characterize recycled construction and demolition waste blocks (RCDW for their thermal properties. The aim of this work was to characterize the RCDW thermal resistance and conductivity in order to provide subsidies for a building's thermal performance analysis. The hot-box method was adapted, together with measuring techniques with a heat-flow meter to determine the RCDW thermal properties. The results indicated that the RCDW block overall thermal resistance and thermal conductivity in the solid region was within the intervals of 0.33≤RT≤0.41m2KW-1 and 0.60≤l≤0.78Wm-1K-1, respectively. The lower resistance and conductivity values are justified by the presence of aggregate with a lower density and lower thermal conductivity than the natural aggregate.

In recent years, urban development and public housing demolition have posed challenges to the social and geographic rootedness of low-income African Americans in urban areas. In particular, in Chicago, widespread public housing demolition, occurring in the context of rapid gentrification, has contributed to increasing shortages of affordable low-income housing. This study uses in-depth interviews and participant observation to examine the migration experiences of men and women who have left urban neighborhoods and public housing developments in Chicago searching for affordable housing and economic opportunity in eastern Iowa. This particular analysis focuses on experiences of social and geographic “rootlessness” that emerged as a major theme in these interviews. Participants describe community dispossession in Chicago that has threatened not only the ties between individuals and their social support networks, but also connections and claims to the places in which these ties are rooted. Narratives that describe leaving Chicago in this context and then trying to get by as a stigmatized outsider in “someone else's city” speak to a process of dislocation that may disrupt critical social-support resources that are known to mitigate the consequences of structural disadvantage.

Multi-unit housing environments remain significant sources of secondhand smoke (SHS) exposure, especially for vulnerable populations in subsidized housing. In Philadelphia, the largest US housing authority to implement smoke-free policies, we measured baseline resident smoking-related behaviors and attitudes, and longitudinal exposures to airborne nicotine, during policy development and implementation. In 4 communities, we collected data in 2013, 2014, and 2016, before and after introduction of comprehensive smoke-free policies, interviewing persons in 172 households, and monitoring air-borne nicotine in non-smoking homes and public areas. Average nicotine level differences across years were estimated with multi-level models. Fifty-six percent of respondents smoked. Only 37% of households were smoke-free, with another 41% restricting smoking by area or time of day. The number of locations with detectable nicotine did not differ before and after policy implementation, with approximately 20% of non-smoking homes and 70%-80% of public areas having detectable nicotine. However, public area nicotine levels were lower in 2016, after policy implementation, than in 2013 and 2014 (-0.19 μg/m 3 , p = .03). Findings suggest that initial policy implementation was associated with reduced SHS exposure in Philadelphia. As HUD strengthens smoke-free policies, SHS monitoring can be useful to educate stakeholders and build support for policy enforcement.

1980-01-01

The US Department of Energy (DOE), Division of Environmental Control Technology, requested Nuclear Energy Services to prepare a handbook for the decontamination and decommissioning (D and D) of DOE-owned and commercially-owned radioactive facilities. the objective of the handbook is to provide the nuclear industry with guidance on the state-of-the-art methods and equipment available for decommissioning and to provide the means to estimate decommissioning costs and environmental impact. The methods available for concrete decontamination and demolition are summarized to provide an overview of some of the state-of-the-art techniques to be discussed at this workshop. The pertinent information on each method will include the selection factors such as the rate of performance in terms of concrete removal per unit time (cubic yards per day), manpower required by craft, unit cost (dollars per cubic yard) and the advantages and disadvantages. The methods included in this overview are those that have been routinely used in nuclear and nonnuclear applications or demonstrated in field tests. These methods include controlled blasting, wrecking ball or slab, backhoe mounted ram, flame torch, thermic lance, rock splitter, demolition compound, sawing, core stitch drilling, explosive cutting, paving breaker and power chisel, drill and spall, scarifying, water cannon and grinding

The management planning of construction and demolition (C&D) waste uses a single indicator which does not provide enough detailed information. Therefore the determination and implementation of other innovative and precise indicators should be determined. The aim of this research work is to improve existing C&D waste quantification tools in the construction of new residential buildings in Spain. For this purpose, several housing projects were studied to determine an estimation of C&D waste generated during their construction process. This paper determines the values of three indicators to estimate the generation of C&D waste in new residential buildings in Spain, itemizing types of waste and construction stages. The inclusion of two more accurate indicators, in addition to the global one commonly in use, provides a significant improvement in C&D waste quantification tools and management planning.

Environmental and economical feasibility of selective demolition project; Viabilidad ambiental y economica de un proyecto de demolicion selectiva: hacia una optima gestion de los RCD

Energy Technology Data Exchange (ETDEWEB)

Vegas, I.

2004-07-01

Selective demolition practices have not yet become popular in our country. Unlike conventional demolition practices, selective demolition helps to increase the amount of components to be reused or materials to be recycled. Thus, the percentage of demolition waste deposited in landfills can be reduced, and the production of recycled materials with optimum quality is fostered. Taking the case study of selective demolition carried out in the municipally of Lasarte-Oria (Basque Country-Spain) as its basis, this paper presents an economic and environmental analysis of the same. Likewise, the economic costs deriving from selective demolition are compared with analogous costs from conventional demolition with an aim to establishing the ideal frame supporting economically feasible selective demolition.

Paz, Diogo Henrique Fernandes da; Lafayette, Kalinny Patrícia Vaz; Sobral, Maria do Carmo

2018-05-01

The objective of this article was to plan a network for municipal management of construction and demolition waste in Brazil with the assistance of a geographic information system, using the city of Recife as a case study. The methodology was carried out in three stages. The first was to map the illegal construction and demolition of waste disposal points across Recife and classify the waste according to its recyclability. In sequence, a method for indicating suitable areas for installation of voluntary delivery points, for small waste generators, are presented. Finally, a method for indicating suitable areas for the installation of trans-shipment and waste sorting areas, developed for large generators, is presented. The results show that a geographic information system is an essential tool in the planning of municipal construction and demolition waste management, in order to facilitate the spatial analysis and control the generation, sorting, collection, transportation, and final destination of construction and demolition waste, increasing the rate of recovery and recycling of materials.

Dubey, Brajesh; Solo-Gabriele, Helena M; Townsendt, Timothy G

2007-03-01

The disaster debris from Hurricane Katrina is one of the largest in terms of volume and economic loss in American history. One of the major components of the demolition debris is wood waste of which a significant proportion is treated with preservatives, including preservatives containing arsenic. As a result of the large scale destruction of treated wood structures such as electrical poles, fences, decks, and homes a considerable amount of treated wood and consequently arsenic will be disposed as disaster debris. In this study an effort was made to estimate the quantity of arsenic disposed through demolition debris generated in the Louisiana and Mississippi area through Hurricane Katrina. Of the 72 million cubic meters of disaster debris generated, roughly 12 million cubic meters were in the form of construction and demolition wood resulting in an estimated 1740 metric tons of arsenic disposed. Management of disaster debris should consider the relatively large quantities of arsenic associated with pressure-treated wood.

Stripping demolition of reinforced concrete by electric heating method

International Nuclear Information System (INIS)

Nakagawa, Wahei; Nishita, Kiwamu; Kasai, Yoshio

1993-01-01

The present paper describes the procedures and results of a series of experiments the authors conducted to verify the efficiency of the electric heating method, previously proposed for so-called stripping demolition by applying electric current through reinforcing bars. In this method, a low voltage high current is run from one end to the other of a reinforcing bar or bars existing in a concrete structure, inducing intense heat in the bar(s) which in its turn brings about cracks in the surrounding concrete mass, facilitating secondary demolition by hammer picks or other means. The experiments were performed on full-scale biological shield wall mock-ups of a BWR and a small reactor. The results of the experiments are summarized as follows. (1) When electric current is applied through reinforcing bars, the bond between concrete and bars is loosened, and cracks start from one bar and progress toward other bars. Under appropriate conditions, the cracks in concrete run from the contact surface at one bar all the way to its the contact surface on another bar. (2) Cracks appear and grow only between two electrodes between which current is applied, not extending out of the area thus defined. (3) The concrete in the region closer to a current-bearing bar is intensely heated, whereas the concrete far from the bars remains nearly unheated. (4) Concrete walls after electric heating of bars disintegrates, if demolished with hammers, with the covering concrete are removed from the remaining portion of the structure together with heated bars, in shapes of flakes. (5) The reinforced concrete collapses in massive pieces of concrete, without generating much dust as is the case with the demolition of a concrete structure not heated by electricity. Results of the experiments show that the electric heating method is worth applying also to the demolition of nuclear power plants where concrete in the radioactivated surface region of shield walls needs to be stripped off in flakes

Housing provision in the Kathmandu Valley: Public agency and private sector initiation

Directory of Open Access Journals (Sweden)

Bijaya K. Shrestha

2010-01-01

Full Text Available The haphazard growth of settlements in the Kathmandu Valley is the result of rapid urbanisation, growing poverty, the high cost of land and construction, and dependence on the traditional practice of owner-built housing. This growth has resulted in huge housing deficits and poor home conditions. The government’s implementation of the site and services programme as well as land-pooling projects in the 1970s and 1980s benefitted local landowners, but private-sector developments in the 1990s and 2000s were only accessible to upper-middle and high-income groups. This has forced the urban poor and economically disadvantaged groups to live in slum and squatter developments. Planned development organisation has been weak in terms of physical layout, the creation of socialisation opportunities and a sense of community, and in achieving a desirable population density. The existing legal and institutional framework is inadequate and ineffective for addressing these issues. To fill the gap between the efforts of the public and private sectors and meet the high demands for housing in the valley, clear-cut policies and planning are required. This must be done in order to link housing supply with demand and to ensure the participation of various public and private-sector agencies in land-development and housing projects that will incorporate the urban poor. Local municipalities should also be equipped for managing local resources, coordinating the agencies involved and monitoring development.

The self-reported prevalence of asthma in the United States increased by 75% from 1980 to 1994, a trend found to be significant and evident in every region of the country. The increase was most marked in children from birth to 14 years of age; and growing evidence indicates that, as with lead poisoning, inner-city and urban populations are most at risk. Attention has turned to the role of indoor environmental risk factors, especially in homes and schools. Such factors include moisture and mold growth, pest infestation, dust mites, the building envelope, heating systems, inadequate ventilation, nitrogen dioxide, and environmental tobacco smoke. The Healthy Public Housing Initiative (HPHI) is a Boston-based community-centered research and intervention project designed to engage Boston Housing Authority residents in a collaborative process to improve respiratory health, quality of life, building conditions, and building maintenance in public housing. This article summarizes the significant research findings from four pilot studies in housing developments that laid the foundation for the larger HPHI asthma-related environmental intervention study. The research design for the pilot projects is informed by principles of community-collaborative research. The strengths of this model of research for our work are also discussed.

Public spaces in a planned housing is a place of social interaction for every visitor of public space. The research on public space image uses four public spaces that meet the criteria of public space such as pedestrian sidewalks, public park, water front and worship place. Research on the perception of public space is interesting to investigate because housing development is part of the forming of a society that should design with proper architectural considerations. The purpose of this research is to know the image of public space on the planned housing in Medan City based on the mapping of environmental and behavior cognition and to know the difference between the image that happened to four group respondent. The research method of architecture used in this research is a descriptive qualitative method with case study approach (most similar case). Analysis of data used using mental maps and questionnaires. Then the image of public space is formed based on the elements of public space, wayfinding, route choice, and movement. The image difference that occurs to the housing residents and architecture students, design and planning are outstanding, visitors to the public housing space is good, people who have never visited the public space is inadequate.

Preventing cancer: a community-based program for youths in public housing.

This article describes a feasibility study of a program that mentors boys aged 14-18 living in inner city public housing, engages them in a basketball league, and provides educational sessions on life skills and ways to resolve conflicts without violence. Such programs have the potential to engage adolescent males living in public housing in activities that reduce cancer-related behaviors and increase protective behaviors. We conducted a feasibility evaluation of the program, which included a survey of participants, interviews with coaches, and observations of games and practices. Lifetime and previous-30-day substance use was common among participants, and many were exposed to and had experienced various forms of violence. Keeping youths active helps prevent their joining gangs and using drugs. Youths from disadvantaged backgrounds are at a high risk for cancer because they are at greater risk for obesity and other adverse health-related conditions than are more affluent youths. Implementing and sustaining community programs for youths in public housing can reduce the effects of exposure to factors that put them at risk for cancer during adulthood: chronic poverty, lack of safe areas for recreation, easy access to alcohol and drugs, and exposure to violence. In addition, workshops to prevent substance use and violence and to teach leadership, sportsmanship, conflict resolution, and healthy youth development are needed for youths, coaches, and parents or guardians.

Application of micro blasting technique to demolition of biological shield wall of reactor building

International Nuclear Information System (INIS)

Kontani, Osamu

2016-01-01

Although heavily reinforced concrete structures in nuclear facilities could be dismantled effectively with the controlled blasting technique, the noises and vibrations caused by blasting were matters of concern. Recently, in the building replacement at urban areas, there are increasing cases of demolition of large reinforced concrete members below ground. Instead of applying heavy weight breakers, the micro blasting technique that enables to lower noises and vibrations has developed and applied to demolition work of large reinforced concrete members in urban areas. In this report, the features of the micro blasting technique is reviewed by comparing with existing controlled blasting technique and its applicability to demolition work of nuclear facilities is investigated. The results of those study find that it is confirmed that the micro blasting technique could be applicable to large reinforced concrete structures in nuclear facilities because of the low levels of noises and vibrations. However, it is recommended to perform mock-up tests to confirm the demolition efficiency and levels of the noises and vibrations since the rebar used in nuclear facilities is larger in diameters and in rebar ratio compared with ordinary reinforced concrete structures.

Distribution of materials in construction and demolition waste in Portugal.

Coelho, André; de Brito, Jorge

2011-08-01

It may not be enough simply to know the global volume of construction and demolition waste (CDW) generated in a certain region or country if one wants to estimate, for instance, the revenue accruing from separating several types of materials from the input entering a given CDW recycling plant. A more detailed determination of the distribution of the materials within the generated CDW is needed and the present paper addresses this issue, distinguishing different buildings and types of operation (new construction, retrofitting and demolition). This has been achieved by measuring the materials from buildings of different ages within the Portuguese building stock, and by using direct data from demolition/retrofitting sites and new construction average values reported in the literature. An attempt to establish a benchmark with other countries is also presented. This knowledge may also benefit industry management, especially that related to CDW recycling, helping to optimize procedures, equipment size and operation and even industrial plant spatial distribution. In an extremely competitive market, where as in Portugal low-tech and high environmental impact procedures remain the norm in the construction industry (in particular, the construction waste industry), the introduction of a successful recycling industry is only possible with highly optimized processes and based on a knowledge-based approach to problems.

Strategy of Construction and Demolition Waste Management after Chemical Industry Facilities Removal

Science.gov (United States)

Tashkinova, I. N.; Batrakova, G. M.; Vaisman, Ya I.

2017-06-01

Mixed waste products are generated in the process of irrelevant industrial projects’ removal if conventional techniques of their demolition and dismantling are applied. In Russia the number of unused chemical industry facilities including structures with high rate of wear is growing. In removing industrial buildings and production shops it is used conventional techniques of demolition and dismantling in the process of which mixed waste products are generated. The presence of hazardous chemicals in these wastes makes difficulties for their use and leads to the increasing volume of unutilized residues. In the process of chemical industry facilities’ removal this fact takes on special significance as a high level of hazardous chemicals in the waste composition demands for the realization of unprofitable measures aimed at ensuring environmental and industrial safety. The proposed strategy of managing waste originated from the demolition and dismantling of chemical industry facilities is based on the methodology of industrial metabolism which allows identifying separate material flows of recycled, harmful and ballast components, performing separate collection of components during removal and taking necessary preventive measures. This strategy has been tested on the aniline synthesis plant being in the process of removal. As a result, a flow of 10 wt. %, subjected to decontamination, was isolated from the total volume of construction and demolition waste (C&D waste). The considered approach allowed using the resource potential of more than 80wt. % of waste and minimizing the disposed waste volume.

Construction and demolition waste generation rates for high-rise buildings in Malaysia.

Mah, Chooi Mei; Fujiwara, Takeshi; Ho, Chin Siong

2016-12-01

Construction and demolition waste continues to sharply increase in step with the economic growth of less developed countries. Though the construction industry is large, it is composed of small firms with individual waste management practices, often leading to the deleterious environmental outcomes. Quantifying construction and demolition waste generation allows policy makers and stakeholders to understand the true internal and external costs of construction, providing a necessary foundation for waste management planning that may overcome deleterious environmental outcomes and may be both economically and environmentally optimal. This study offers a theoretical method for estimating the construction and demolition project waste generation rate by utilising available data, including waste disposal truck size and number, and waste volume and composition. This method is proposed as a less burdensome and more broadly applicable alternative, in contrast to waste estimation by on-site hand sorting and weighing. The developed method is applied to 11 projects across Malaysia as the case study. This study quantifies waste generation rate and illustrates the construction method in influencing the waste generation rate, estimating that the conventional construction method has a waste generation rate of 9.88 t 100 m -2 , the mixed-construction method has a waste generation rate of 3.29 t 100 m -2 , and demolition projects have a waste generation rate of 104.28 t 100 m -2 . © The Author(s) 2016.

Global city aspirations, graduated citizenship and public housing: analysing the consumer citizenships of neoliberalism

Directory of Open Access Journals (Sweden)

Dallas Rogers

2014-01-01

Full Text Available Global city discourses rearticulate the relationships between the state, urban space and the global economy. At the local level, global city reconfigurations stamp the mark of a global economic order onto local citizenship practices. Public housing is a legacy of specific national (welfare states where citizenship rights arose from territorially bound constitutional discourses, and is incompatible in its current form with the consumer-based rights and responsibilities of a global economic order. At the same time, property markets in high-value areas of cities like Sydney, Australia, see not only increasing presence of international investment but fundamental changes in planning and governance processes in order to facilitate it. Global market-oriented discourses of urban governance promote consumer “performances of citizenship” and a graduated approach to the distribution of rights, including the right to housing. In this article we explore what is new about neoliberal approaches to public and social housing policy, and how public tenants respond to and negotiate it. In Australia tenants’ right to participate in local-level democracy, and in housing management, must be reconsidered in light of the broader discourses of consumer citizenship that are now enforced on tenants as a set of “responsibilities” to the market and state.

The work of the National Economic Development Office Demolition and Dismantling Group in four areas which are crucial to the economic performance of the demolition and dismantling industry and its safety record is considered. The first concerns the availability and accessibility of information about unconventional structures and details are given of the sort of information often kept for different types of structure. Secondly, the need is stressed for guidelines for the client, particularly on the risks involved and the choice of a competent contractor. Thirdly, basic credentials which it is important for contractors to set out in order to establish a good reputation for the industry are set out. Finally, the particular case of nuclear power station decommissioning is considered with reference to the size of the market, the pioneering knowledge to be gained from the decommissioning of the Windscale Advanced Gas-cooled Reactor, private sector involvement and the special techniques required.

A BIM-based system for demolition and renovation waste estimation and planning.

Science.gov (United States)

Cheng, Jack C P; Ma, Lauren Y H

2013-06-01

Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C&D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D&R) works and the growing amount of D&R waste disposed to landfills every day, especially in developed cities like Hong Kong. Quantitative waste prediction is crucial for waste management. It can enable contractors to pinpoint critical waste generation processes and to plan waste control strategies. In addition, waste estimation could also facilitate some government waste management policies, such as the waste disposal charging scheme in Hong Kong. Currently, tools that can accurately and conveniently estimate the amount of waste from construction, renovation, and demolition projects are lacking. In the light of this research gap, this paper presents a building information modeling (BIM) based system that we have developed for estimation and planning of D&R waste. BIM allows multi-disciplinary information to be superimposed within one digital building model. Our system can extract material and volume information through the BIM model and integrate the information for detailed waste estimation and planning. Waste recycling and reuse are also considered in our system. Extracted material information can be provided to recyclers before demolition or renovation to make recycling stage more cooperative and more efficient. Pick-up truck requirements and waste disposal charging fee for different waste facilities will also be predicted through our system. The results could provide alerts to contractors ahead of time at project planning stage. This paper also presents an example scenario with a 47-floor residential building in Hong Kong to demonstrate our D&R waste estimation and planning system. As the BIM technology has been increasingly adopted in the architectural, engineering and construction industry

Use of demolition residues construction in soil-lime bricks

International Nuclear Information System (INIS)

Figueiredo, S.S.; Silva, C.G.; Silva, I.A.; Neves, G.A.

2011-01-01

Besides being responsible for several environmental damage caused by its residues, the construction industry is also considered the greatest natural resources consumer. When finely ground, such residues can exhibit cementing properties, which may replace part of the lime used in the manufacture of soil-lime bricks. This study aimed to verify the viability of using demolition residues (DR) in soil-lime bricks without structural function. For this, test specimens were prepared using mixes in a 1:10 ratio of lime:soil and embedding residue in partial replacement of lime in the proportions of 25%, 50% and 75%. The test specimens were submitted to curing periods of 28 and 52 days, then it was determined the compression strength. The results showed that when embedded on moderate percentages, demolition residues construction can be used in the production of soil-lime bricks. (author)

Postwar City: Importance of Recycling Construction and Demolition Waste

Science.gov (United States)

Al-Qaraghuli, Hanan; Alsayed, Yaman; Almoghazy, Ali

2017-10-01

Wars and armed conflicts have heavy tolls on the built environment when they take place in cities. It is not only restricted to the actually fighting which destroys or damages buildings and infrastructure, but the damage and destruction inflicts its impacts way beyond the cessation of military actions. They can even have another impact through physical segregation of city quarters through walls and checkpoints that complicates, or even terminates, mobility of citizens, goods, and services in the post-war scenario. The accumulation of debris in the streets often impedes the processes of rescue, distribution of aid and services, and other forms of city life as well. Also, the amount of effort and energy needed to remove those residual materials to their final dumping sites divert a lot of urgently needed resources. In this paper, the components of construction and demolition waste found in post-war cities are to be discussed, relating each one to its origins and potential reuses. Then the issues related to the management of construction waste and demolition debris resulting from military actions are to be discussed. First, an outlook is to be given on the historical example of Berlin and how the city was severely damaged during World War II, and how the reconstruction of the city was aided in part by the reuse of demolition debris. Then two more recent examples will be given, the cities of Baghdad in Iraq, and Homs in Syria. In Baghdad, though major military actions have ceased but not all rubble is cleared out, some security structures in the form of concrete walls separate the cities into quarters and impede city life and lie around as poorly allocated resource needed for reconstruction. While in the case of Homs, and the wider Syrian context, major military operations are still raging, making more pressure on the resources needed for reconstruction. This recycling of demolition debris can bring economic and social stability through the conservation of resources

Lambertino, Anissa; Turyk, Mary E; Curtis, Luke; Persky, Victoria W

2009-03-01

Residents of public housing can experience socioeconomic disadvantages, inadequate access to health care, and particularly substandard indoor air quality due to inadequate building maintenance. This study investigates demographic, medical management, severity, and household factors associated with asthma-related emergency department visits and hospitalizations. A total of 103 adult participants with asthma from four Chicago housing developments completed surveys and underwent household inspections. Using stepwise multivariate logistic regression, we identified independent predictors of asthma-related emergency department visits: asthma controller medication use, not keeping an asthma-related doctor's appointment, and frequent nocturnal wheeze episodes. Using stepwise multivariate logistic regression, we identified independent predictors of asthma-related hospitalizations: peeling paint, plaster, or wallpaper, environmental tobacco smoke, written action plan for an asthma-related doctor or emergency department visit, and frequent nocturnal wheeze episodes. In multivariate models, factors related to clinical severity and asthma management were related to both emergency department visits and hospitalizations while household conditions were related only to hospitalizations. Interventions to address both asthma management and household environmental triggers may be needed to reduce asthma morbidity in low-income populations.

Y-12 Construction/Demolition Landfill VII: Permit application: Part 1 and 2

International Nuclear Information System (INIS)

1992-04-01

The United States Department of Energy (DOE) has three major operating facilities on the DOE Oak Ridge Reservation (ORR) at Oak Ridge, Tennessee: the Y-12 Plant, the K-25 Site, and the Oak Ridge National Laboratory (ORNL). Operations associated with the DOE energy research and production facilities at Oak Ridge result in the production of several types of waste materials. Disposal of solid waste (as defined in the Solid Waste Processing and Disposal Rules for Tennessee) in disposal facilities operated by the Y-12 Plant is the responsibility of Y-12 Waste Management Division (MWD). The WMD is proposing to develop a facility that will include two new disposal units: one for construction/demolition waste and spoil and one for industrial solid waste. This manual describes the closure and post-closure plans for the construction/demolition waste and spoil disposal unit. This disposal unit is referred to as the Y-12 Construction/Demolition Landfill VII (CD-VII) and is to be operated by the Y-12 Plant for the DOE. This will be a Tennessee Department of Environment and Conservation/Division of Solid Waste Management (TDEC/DSWM) Class IV disposal unit

Quantum demolition filtering and optimal control of unstable systems.

Science.gov (United States)

Belavkin, V P

2012-11-28

A brief account of the quantum information dynamics and dynamical programming methods for optimal control of quantum unstable systems is given to both open loop and feedback control schemes corresponding respectively to deterministic and stochastic semi-Markov dynamics of stable or unstable systems. For the quantum feedback control scheme, we exploit the separation theorem of filtering and control aspects as in the usual case of quantum stable systems with non-demolition observation. This allows us to start with the Belavkin quantum filtering equation generalized to demolition observations and derive the generalized Hamilton-Jacobi-Bellman equation using standard arguments of classical control theory. This is equivalent to a Hamilton-Jacobi equation with an extra linear dissipative term if the control is restricted to Hamiltonian terms in the filtering equation. An unstable controlled qubit is considered as an example throughout the development of the formalism. Finally, we discuss optimum observation strategies to obtain a pure quantum qubit state from a mixed one.

The FRJ-1 (MERLIN) research reactor: its main activity inventory has been removed by successful demolition of the reactor block

International Nuclear Information System (INIS)

Stahn, B.; Printz, R.; Matela, K.; Zehbe, C.; Poeppinghaus, J.; Cremer, J.

2004-01-01

The FRJ-1 (MERLIN) research reactor was decommissioned in 1985 after twenty-three years of operation. Demolition of the plant was begun in 1996. The article contains a survey of the demolition steps carried out so far within the framework of three partial permits. The main activity is the demolition of the reactor core structures as a precondition for subsequent measures to ensure clearance measurements of the building. The core structures are demolished which were exposed to high neutron fluxes during reactor operation and now show the highest activity and dose rate levels, except for the core internals. For demolition and disassembly of the metal structures in this part of the plant, the tools specially designed and made include a remotely operated sawing system and a pipe cutting system for internal segmentation of the beam lines. The universal demolition tool for use also above and beyond the concrete structures has been found to be a remotely controlled electrohydraulic demolition shovel. Spreading contamination in the course of the demolition work was avoided. One major reason for this success was the fact that no major airborne contamination existed at any time as a consequence of the quality of the material demolished and also of the consistent use of technical tools. While the reactor block was being demolished, an application for clearance measurement of the reactor hall and subsequent release from the scope of the Atomic Energy Act was filed as early as in mid-2003. The fourth partial permit covering these activities is expected to be issued in the spring of 2004. (orig.)

Few published community garden studies have focused on low socio-economic youth living in public housing or used a community-based participatory research approach in conjunction with youth-focused community garden programmes. The objective of the present study was to evaluate the feasibility (i.e. demand, acceptability, implementation and limited-effectiveness testing) of a 10-week experiential theory-based gardening and nutrition education programme targeting youth living in public housing. In this mixed-methods feasibility study, demand and acceptability were measured using a combination of pre- and post-programme surveys and interviews. Implementation was measured via field notes and attendance. Limited-effectiveness was measured quantitatively using a pre-post design and repeated-measures ANOVA tests. Two public housing sites in the Dan River Region of south central Virginia, USA. Forty-three youth (primarily African American), twenty-five parents and two site leaders. The positive demand and acceptability findings indicate the high potential of the programme to be used and be suitable for the youth, parents and site leaders. Field notes revealed numerous implementation facilitators and barriers. Youth weekly attendance averaged 4·6 of 10 sessions. Significant improvements (Pgardening knowledge, knowledge of MyPlate recommendations), but not all limited-effectiveness measures (e.g. willingness to try fruits and vegetables, fruit and vegetable eating self-efficacy). This community-based participatory research study demonstrates numerous factors that supported and threatened the feasibility of a gardening and nutrition programme targeting youth in public housing. Lessons learned are being used to adapt and strengthen the programme for future efforts targeting fruit and vegetable behaviours.

Exploring Factors Affecting Implementation of Public Private Partnership Housing Projects in Bauchi State, Nigeria

Directory of Open Access Journals (Sweden)

Mohammed Sani

2018-03-01

Full Text Available Public Private Partnership (PPP Housing scheme in Nigeria is intended to complement government effort toward increasing housing stock and providing affordable housing in the country. However, Bauchi state government adopted the construction of 5,000 phases PPP Housing. But 6 years after the commencement of the scheme, only a few numbers of housing units were completed and commissioned. Therefore, it becomes imperative to carry out research on the impact level of those factors affecting the implementation of the scheme. The aim of the study is to investigate impact level of factors affecting the implementation of PPP housing projects in Bauchi state with a view to find out possible ways that will improve the implementation of the scheme. The descriptive and explorative research design was adopted for this study. 54 structured Questionnaires were administered to construction professional’s staff under private housing developers and relevant government agencies in Bauchi state. 42 valid Questionnaires were retrieved and analysed with SPSS software. The result of the quantitative data analysis shows that creation of favourable investment environment and government support have very high Impact on the implementation of Bauchi PPP housing projects. Therefore, this study recommends that government and other stakeholders should give more attention to the creation of favourable investment environment, support in policy formulation and managerial strategies in the future for improving the implementation of PPP housing projects.

Influence of construction and demolition waste management on the environmental impact of buildings.

Science.gov (United States)

Coelho, André; de Brito, Jorge

2012-03-01

The purpose of this study is to quantify comparable environmental impacts within a Life Cycle Analysis (LCA) perspective, for buildings in which the first (Materials) and last (End of Life) life cycle stages are adjusted to several waste/material management options. Unlike most LCAs, the approach is "top-down" rather than "bottom-up", which usually involves large amounts of data and the use of specific software applications. This approach is considered appropriate for a limited but expedient LCA designed to compare the environmental impacts of different life cycle options. Present results, based on real buildings measurements and demolition contractor activities, show that shallow, superficial, selective demolition may not result in reduced environmental impacts. Calculations actually show an increase (generally less than 5%) in most impact categories for the Materials and End of Life stages because of extra transportation needs. However, core material separation in demolition operations and its recycling and/or reuse does bring environmental benefits. A reduction of around 77% has been estimated in the climate change impact category, 57% in acidification potential and 81% in the summer smog impact (for the life cycle stages referred).

A change in strategy for a CERCLA Removal Action Demolition Project in progress results in overall project enhancements

International Nuclear Information System (INIS)

Albertin, M.; Nichols, R.M.; Edwards, D.T.

1995-01-01

This paper discusses changes made in a demolition project at the Fernald Environmental Management Project (FEMP), a site on the National Priorities list (NPL), owned by the Department of Energy. The project, to demolish fourteen uranium ore silos and their structure, was based on a Removal Action Work Plan, submitted and approved by the United States Environmental Protection Agency (USEPA), that integrated Comprehensive Environmental Response Compensation and Liability Act (CERCLA) requirements to remove the source of contamination and threat to public health and the environment. After the demolition contractor defaulted at 30% complete, completion of the project by the USEPA deadline was threatened. The recovery plan included re-evaluation of project documents in addition to the schedule. It was determined that re-interpretation of the removal action criteria, including design and Removal Action Work Plan, would eliminate road-blocks, and optimize resources, resulting in project completion by the original deadline even after lost-time in mobilizing another contractor. This presentation will discuss the open-quotes lessons learnedclose quotes by the project team and illustrate how simplification of construction methods resulted in enhancements to the environmental controls, improved material handing, and created a safer work environment

1998-01-01

A target fibre survey was conducted to assess the random occurrence of a blue wool fibre on seats in public houses throughout the United Kingdom. Fibre tape lifts were taken from 80 seats. Four seats yielded matching fibres and five of these were found on one seat. A total of 292 fibres were identified; nine fibres proved indistinguishable from the target after comparison microscopy, microspectro-photometry and attempts at thin layer chromatography, and two of these fibres were still apparently indistinguishable after TLC analysis although only one dye component was visible.

Anxiety and depression in socioeconomically disadvantaged older adults frequently go unrecognized and untreated. This study aims to characterize mental illness and its treatment in older adult public housing residents who have many risk factors for anxiety and depression. Cross-sectional study. Public housing high-rises in Rochester, New York. One hundred ninety residents aged 60 years and older. Anxiety and depression were assessed using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, GAD-7, and Patient Health Questionnaire. We obtained information on mental healthcare from medication review and self-report. Participants had a median age of 66 years, 58% were women, 80% were black, and 92% lived alone. Many participants (31%) were in need of mental healthcare: 21% had syndromal and 11% had subsyndromal anxiety or depression. Mental healthcare need was associated with younger age; intact cognitive functioning; impairments in instrumental activities of daily living (IADL); more medical illness; decreased mobility; smaller social network size; more severe life events; and increased utilization of medical, human, and informal services. Of those with mental healthcare need, most were not receiving it. Compared with residents receiving mental healthcare, residents with untreated need were more likely to be men and have less IADL impairment, medical illness, severe life events, onsite social worker use, and human services utilization. Mental illness was common and largely untreated in public housing residents. Increasing collaboration between medical, mental, and human services is needed to improve identification, treatment, and ultimately prevention of late-life mental illness in this community setting.

The role of public spaces in creating place attachment (example of Zacisze, Warsaw housing estate

Directory of Open Access Journals (Sweden)

Mantey Dorota

2015-09-01

Full Text Available This article raises the question of place attachment in the context of an increasingly important factor, that is the use of gathering and leisure places. The author publishes findings of a survey conducted among the residents of Zacisze, Warsaw, a detached housing estate with a very poor range of public places for gathering and leisure. The study has proved that the use of local public spaces, as a specific category of place, reinforces attachment to the whole housing estate. The study also confirms the important role that social factors have in building place attachment. Conditions already exist for considering social factors more important than physical ones in building a positive relationship with a territory.

This project was conducted to evaluate buildings and facilities remaining in the Washington Closure Hanford (WCH) deactivation, decontamination, decommissioning, and demolition schedule for bat roost sites. The project began in spring of 2009 and was concluded in spring of 2011. A total of 196 buildings and facilities were evaluated for the presence of bat roosting sites. The schedule for the project was prioritized to accommodate the demolition schedule. As the surveys were completed, the results were provided to the project managers to facilitate planning and project completion. The surveys took place in the 300 Area, 400 Area, 100-H, 100-D, 100-N, and 100-B/C Area. This report is the culmination of all the bat surveys and summarizes the findings by area and includes recommended mitigation actions where bat roosts were found.

Context, built form and space: A case of public housing estates in Hong Kong

Directory of Open Access Journals (Sweden)

Rumana Afroz

2012-06-01

Full Text Available The context of public housing development in Hong Kong can be traced back to a deep rooted history when it was a need rather than a choice. At present, the public housing estates have become a much desired residential destination by the general people of Hong Kong although several changes in design have been observed that are not completely adapted by the residents. This study aims to investigate on the changing phenomenon of the context and the built form; and its impact on space in terms of adaptability by the residents. It has been found that, forced or formal communal spaces influenced by self-conscious culture discourage social interaction where quantitative measures are only applied, and informal communal spaces encouraged by unselfconscious culture bring happy social life. Contemporary built forms in the housing estates have changed a lot both externally and internally, and attention has been given to quantitative measures and formal spatial arrangements. As a result a gap is emerging between context, built form and adapted use of space. Therefore, measures such as qualitative approach, sensitively designed spatial arrangements are recommended to minimize the gap.

Coal and wood fuel for electricity production: An environmentally sound solution for waste and demolition wood

Energy Technology Data Exchange (ETDEWEB)

Penninks, F.W.M. [EPON, Zwolle (Netherlands)

1997-12-31

Waste wood from primary wood processing and demolition presents both a problem and a potential. If disposed in landfills, it consumes large volumes and decays, producing CH{sub 4}, CO{sub 2} and other greenhouse gases. As an energy source used in a coal fired power plant it reduces the consumption of fossil fuels reducing the greenhouse effect significantly. Additional advantages are a reduction of the ash volume and the SO{sub 2} and NO{sub x} emissions. The waste wood requires collection, storage, processing and burning. This paper describes a unique project which is carried out in the Netherlands at EPON`s Gelderland Power Plant (635 MW{sub e}) where 60 000 tonnes of waste and demolition wood will be used annually. Special emphasis is given to the processing of the powdered wood fuel. Therefore, most waste and demolition wood can be converted from an environmental liability to an environmental and economic asset. (author)

A Visual Analysis Approach for Inferring Personal Job and Housing Locations Based on Public Bicycle Data

Directory of Open Access Journals (Sweden)

Xiaoying Shi

2017-07-01

Full Text Available Information concerning the home and workplace of residents is the basis of analyzing the urban job-housing spatial relationship. Traditional methods conduct time-consuming user surveys to obtain personal job and housing location information. Some new methods define rules to detect personal places based on human mobility data. However, because the travel patterns of residents are variable, simple rule-based methods are unable to generalize highly changing and complex travel modes. In this paper, we propose a visual analysis approach to assist the analyzer in inferring personal job and housing locations interactively based on public bicycle data. All users are first clustered to find potential commuting users. Then, several visual views are designed to find the key candidate stations for a specific user, and the visited temporal pattern of stations and the user’s hire behavior are analyzed, which helps with the inference of station semantic meanings. Finally, a number of users’ job and housing locations are detected by the analyzer and visualized. Our approach can manage the complex and diverse cycling habits of users. The effectiveness of the approach is shown through case studies based on a real-world public bicycle dataset.

To guide targeted cessation and prevention programming, this study assessed smoking prevalence and described sociodemographic, health, and healthcare use characteristics of adult smokers in public housing. Self-reported data were analyzed from a random sample of 1664 residents aged 35 and older in ten New York City public housing developments in East/Central Harlem. Smoking prevalence was 20.8%. Weighted log-binomial models identified to be having Medicaid, not having a personal doctor, and using health clinics for routine care were positively associated with smoking. Smokers without a personal doctor were less likely to receive provider quit advice. While most smokers in these public housing developments had health insurance, a personal doctor, and received provider cessation advice in the last year (72.4%), persistently high smoking rates suggest that such cessation advice may be insufficient. Efforts to eliminate differences in tobacco use should consider place-based smoking cessation interventions that extend cessation support beyond clinical settings.

Project to design and develop an energy-related program: For public housing residents and renters: Volume 1, Final report

Energy Technology Data Exchange (ETDEWEB)

1988-05-01

This demonstration project was undertaken as a result of an unsolicited proposal submitted by THE ASSIGNMENT GROUP (TAG) to the Office of Minority Economic Impact, Department of Energy (DOE). The problem to which the proposal responded was how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The size and gravity of the problem necessitated a purpose or aim that had nationwide application, yet lent itself to a microscopic look. Consequently, the goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilitates indigenous business development where appropriate, and trains residents to provide needed services.

Downcycling versus recycling of construction and demolition waste: Combining LCA and LCC to support sustainable policy making.

Science.gov (United States)

Di Maria, Andrea; Eyckmans, Johan; Van Acker, Karel

2018-05-01

Urgent solutions are needed in Europe to deal with construction and demolition waste (CDW). EU policy has contributed to significantly reducing the amount of CDW going to landfill, but most of the effort has been put in downcycling practices. Therefore, further policies are needed to stimulate high-quality recycling of CDW. The present paper presents a combined life cycle assessment (LCA) and life cycle costing (LCC) methodologies to analyse the environmental and the economic drivers in four alternative CDW end-of-life scenarios in the region of Flanders, in Belgium. The four analysed alternatives are (i) landfilling, (ii) downcycling, (iii) advanced recycling and (iv) recycling after selective demolition. LCA results show that landiflling is the scenario having the highest environmental impacts in terms of person equivalent (PE), followed by downcycling and recycling (-36%) and recycling after selective demolition (-59%). The decrease in environmental impacts is mostly due to the avoided landfilling of CDW and the recovery of materials from selective demolition. LCC results indicate that landfilling is the scenario bearing the highest total economic costs. This is due to the high landfill tax in Flanders. The recycling after selective demolition bears the second highest cost. The increase of high-quality CDW recycling can significantly reduce the overall environmental impact of the system. Implementing a high landfill tax, increasing the gate fee to the recycling plant, and boosting the sales price of recycled aggregates are the most effective drivers to facilitate a transition towards a more sustainable CDW management system. The paper demonstrates that the combined LCA and LCC results can highlight the environmental and economic drivers in CDW management. The results of the combined analysis can help policymakers to promote the aspects contributing to sustainability and to limit the ones creating a barrier. Copyright © 2018 Elsevier Ltd.

This study investigated the generation and management of demolition waste (DW) in Cyprus. A methodology has been developed and applied for the estimation of the quantities of the waste stream under examination, since quantitative primary data were not available. The existing situation relating to the practices applied for the management of DW was investigated and assessed. Furthermore, a multi-criteria analysis method (PROMETHEE II) was developed and applied in order to examine alternative systems that could be implemented for the management of the DW in the country. In particular, nine management systems (scenarios) were examined, evaluated and ranked according to their efficiency using seventeen individual criteria, divided into four groups (social-legislative, environmental, economic and technical). The ranking of the alternative waste management scenarios indicated that the optimum management system for possible implementation in the island included complete selective demolition procedures and transfer of mixed recyclable materials to the recycling centre and non-recyclable material to landfill.

2017-01-01

Demolition ceramic wastes (DCWs) were investigated in order to determine their potential use as supplementary cementitious materials in Portland Blended Cements (PBCs). For this purpose, three ceramic wastes were investigated. After characterization of the materials used, the effect of ceramic waste replacement (8, 24 and 40% by mass) was analyzed. Pozzolanic activity, hydration progress, workability and compressive strength were determined at 2, 7 and 28 days. The results showed that the ground wastes behave as filler at an early age, but as hydration progresses, the pozzolanic activity of ceramic waste contributes to the strength requirement. [es

Recycling of rubble from building demolition for low-shrinkage concretes.

Science.gov (United States)

Corinaldesi, Valeria; Moriconi, Giacomo

2010-04-01

In this project concrete mixtures were prepared that were characterized by low ductility due to desiccation by using debris from building demolition, which after a suitable treatment was used as aggregate for partial replacement of natural aggregates. The recycled aggregate used came from a recycling plant, in which rubble from building demolition was selected, crushed, cleaned, sieved, and graded. Such aggregates are known to be more porous as indicated by the Saturated Surface Dry (SSD) moisture content. The recycled concrete used as aggregates were added to the concrete mixture in order to study their influence on the fresh and hardened concrete properties. They were added either after water pre-soaking or in dry condition, in order to evaluate the influence of moisture in aggregates on the performance of concrete containing recycled aggregate. In particular, the effect of internal curing, due to the use of such aggregates, was studied. Concrete behavior due to desiccation under dehydration was studied by means of both drying shrinkage test and German angle test, through which shrinkage under the restrained condition of early age concrete can be evaluated.

An estimation framework for building information modeling (BIM)-based demolition waste by type.

Science.gov (United States)

Kim, Young-Chan; Hong, Won-Hwa; Park, Jae-Woo; Cha, Gi-Wook

2017-12-01

Most existing studies on demolition waste (DW) quantification do not have an official standard to estimate the amount and type of DW. Therefore, there are limitations in the existing literature for estimating DW with a consistent classification system. Building information modeling (BIM) is a technology that can generate and manage all the information required during the life cycle of a building, from design to demolition. Nevertheless, there has been a lack of research regarding its application to the demolition stage of a building. For an effective waste management plan, the estimation of the type and volume of DW should begin from the building design stage. However, the lack of tools hinders an early estimation. This study proposes a BIM-based framework that estimates DW in the early design stages, to achieve an effective and streamlined planning, processing, and management. Specifically, the input of construction materials in the Korean construction classification system and those in the BIM library were matched. Based on this matching integration, the estimates of DW by type were calculated by applying the weight/unit volume factors and the rates of DW volume change. To verify the framework, its operation was demonstrated by means of an actual BIM modeling and by comparing its results with those available in the literature. This study is expected to contribute not only to the estimation of DW at the building level, but also to the automated estimation of DW at the district level.

Construction and demolition waste as a source of PVC for recycling.

Science.gov (United States)

Prestes, Sabrina Moretto Darbello; Mancini, Sandro Donnini; Rodolfo, Antonio; Keiroglo, Raquel Carramillo

2012-02-01

Construction and demolition waste can contain considerable amounts of polyvinyl chloride (PVC). This paper describes a study of the recycling of PVC pipes collected from such waste materials. In a sorting facility for the specific disposal of construction and demolition waste, PVC was found to represent one-third of the plastics separated by workers. Pipes were sorted carefully to preclude any possible contamination by poly(ethylene terephthalate) (PET) found in the waste. The material was ground into two distinct particle sizes (final mesh of 12.7 and 8 mm), washed, dried and recycled. The average formulation of the pipes was determined based on ash content tests and used in the fabrication of a similar compound made mainly of virgin PVC. Samples of recycled pipes and of compound based on virgin material were subjected to tensile and impact tests and provided very similar results. These results are a good indication of the application potential of the recycled material and of the fact that longer grinding to obtain finer particles is not necessarily beneficial.

In Canada, public housing programs are an important part of governmental strategies to fight poverty and public exclusion. The Flash on my neighborhood! project is a four-year multiphase community-based participatory action research strategy currently implemented in six public housing developments (n = 1009 households) across the province of Québec, Canada. The goal is to reduce the mental health disparities faced by these public housing tenants compared to the general population, while identifying which environmental and policy changes are needed to turn public housing settings into healthier environments. The protocol involves three successive, interconnected phases: 1) Strengths and needs assessment, including community outreach and recruitment of tenants to collaborate as peer researchers, an exploratory qualitative component (photovoice), a systematic neighborhood observation, and a household survey; 2) Action plan development, including a community forum and interactive capacity-building and discussion sessions; 3) Action plan implementation and monitoring. The entire intervention is evaluated using a mixed-method design, framed within a multiple case study perspective. Throughout the project and particularly in the evaluation phase, data will be collected to record a) contextual factors (tenants' previous experience of participation, history of public housing development, etc.); b) activities that took place and elements from the action plan that were implemented; and c) short- and medium-term outcomes (objective and perceived improvements in the quality of the residential setting, both physically and in terms of mental health and social capital). The study will provide unprecedented evidence-based information on the key ingredients of a collective intervention process associated with the increased collective empowerment and positive mental health of public housing tenants.

Methods The protocol involves three successive, interconnected phases: 1 Strengths and needs assessment, including community outreach and recruitment of tenants to collaborate as peer researchers, an exploratory qualitative component (photovoice, a systematic neighborhood observation, and a household survey; 2 Action plan development, including a community forum and interactive capacity-building and discussion sessions; 3 Action plan implementation and monitoring. The entire intervention is evaluated using a mixed-method design, framed within a multiple case study perspective. Throughout the project and particularly in the evaluation phase, data will be collected to record a contextual factors (tenants’ previous experience of participation, history of public housing development, etc.; b activities that took place and elements from the action plan that were implemented; and c short- and medium-term outcomes (objective and perceived improvements in the quality of the residential setting, both physically and in terms of mental health and social capital. Discussion The study will provide unprecedented evidence-based information on the key ingredients of a collective intervention process associated with the increased collective empowerment and positive mental health of public housing tenants.

2009-01-01

Work practices can influence exposure, especially in small-scale operations conducted by mobile work crews. This study evaluated the use of information on good work practice in control guidance sheets adapted from UK Silica Essentials guidance sheets by trained workers and supervisors employed in small-scale concrete and masonry demolition operations. A one-page employee silica task-based control guidance sheet for each of four demolition tasks and multiple-page silica control guidance for supervisors were developed. Interactive, hands-on worker training on these task-based good work practice controls was developed. Training was presented to 26 participants from two demolition crews. Feedback on the training and task-based good work practice control guidance sheets was elicited. Observations of work practices were made before and after training. Participants indicated gains in knowledge and checklists were used to document skill attainment. The quality of the training and usefulness of the material/skills was rated high by trainees. Increased use of water to suppress dust and wet cleaning methods on the job were documented following the training. Additional follow-up after training is required to determine long-term impact on sustained changes in work practices, and to evaluate the need for refresher training.

Located in Area 25 of the Nevada Test Site (NTS), the Test Cell A (TCA) Facility (Figure 1) was used in the early to mid-1960s for testing of nuclear rocket engines, as part of the Nuclear Rocket Development Program, to further space travel. Nuclear rocket testing resulted in the activation of materials around the reactors and the release of fission products and fuel particles. The TCA facility, known as Corrective Action Unit 115, was decontaminated and decommissioned (D and D) from December 2004 to July 2005 using the Streamlined Approach for Environmental Restoration (SAFER) process, under the Federal Facility Agreement and Consent Order. The SAFER process allows environmental remediation and facility closure activities (i.e., decommissioning) to occur simultaneously, provided technical decisions are made by an experienced decision maker within the site conceptual site model. Facility closure involved a seven-step decommissioning strategy. First, preliminary investigation activities were performed, including review of process knowledge documentation, targeted facility radiological and hazardous material surveys, concrete core drilling and analysis, shield wall radiological characterization, and discrete sampling, which proved to be very useful and cost-effective in subsequent decommissioning planning and execution and worker safety. Second, site setup and mobilization of equipment and personnel were completed. Third, early removal of hazardous materials, including asbestos, lead, cadmium, and oil, was performed ensuring worker safety during more invasive demolition activities. Process piping was to be verified void of contents. Electrical systems were de-energized and other systems were rendered free of residual energy. Fourth, areas of high radiological contamination were decontaminated using multiple methods. Contamination levels varied across the facility. Fixed beta/gamma contamination levels ranged up to 2 million disintegrations per minute (dpm)/100

The self-reported prevalence of asthma increased by 75% from 1980 to 1994, a trend found to be significant and evident in every region of the country. The increase has been most marked in children 0-14 years of age, and there is evidence that, as with lead poisoning, inner-city and urban populations are most at risk. Attention has turned to the role of indoor environment risk factors, especially in homes and schools. Such factors include moisture and mold growth, pest infestation, dust mites, the building envelope, heating systems, inadequate ventilation, NO2, and environmental tobacco smoke. The Healthy Public Housing Initiative (HPHI) is a Boston-based community-centered research and intervention project designed to engage Boston Housing Authority residents in a collaborative process to improve respiratory health, quality of life, building conditions, and building maintenance in public housing. This article summarizes the significant research findings from four pilot studies in housing developments that lay the foundation for the larger HPHI asthma-related environmental intervention study. The research design for the pilot projects is informed by principles of community-collaborative research. The strengths of this model of research to our work are also discussed.

The past couple of years have seen the continuous further development of cutting techniques employed in demolishing nuclear facilities. This trend is continuing. After mostly mechanical cutting techniques had been used initially, there has been a tendency in the past few years to make increasing use of thermal cutting. Reasons for this preference are the reduced space requirement and the advantages this technique offers in remote handling because of the low weight and the small dimensions of the cutting heads, and the high flexibility in materials to be cut. This results in greater planning reliability in calculating quotations and performing the demolition work. The emissions generated by these techniques are manageable reliably at low additional expense for the required extraction and filter systems. Thermal cutting is likely to achieve wide use in dismantling and demolition of nuclear plant components also in the future. Advanced developments in computer hardware and software allow more and more detailed planning of demolition work. While, in the past, CAD had been applied only to generate two-dimensional drawings, current 3D applications allow animated representations of entire demolition scenes with high accuracy in detail. In this way, potential problems associated with handling large components or using manipulators for cutting can be detected and solved much more easily in the preparatory phase. Although current CAD use can be no substitute for mockup tests, it does help to enhance clearly reliability in planning prior to running mockup tests. (orig.)

Structural factors associated with public housing contribute to living environments that expose families to adverse life events that may in turn directly impact parenting and youth outcomes. However, despite the growth in research on fathers, research on families in public housing has practically excluded fathers and the role fathers play in the well-being of their adolescents. Using a sample of 660 African American adolescents recruited from public housing, we examined the relationship between paternal caregivers' (i.e., fathers' and father figures') parenting practices and adolescents' depressive symptoms, attitudes toward deviance, and self-efficacy. Using a latent profile analysis (LPA), we confirmed a four-class model of paternal parenting practices ranging from high to low levels of monitoring and encouragement. Results from a one-way ANOVA indicated that paternal caregivers with high (compared to moderate) levels of encouragement and monitoring were associated with youth who reported less depressive symptoms, higher levels of self-efficacy, and less favorable attitudes toward deviance. Discriminant analysis results indicated that approximately half of the sample were correctly classified into two paternal caregiver classes. The findings provide evidence that some of these caregivers engage in parenting practices that support youths' psychological functioning. More research is needed to determine what accounts for the variability in levels of paternal encouragement and supervision, including environmental influences, particularly for paternal caregivers exhibiting moderate-to-low levels of paternal encouragement and monitoring. © 2016 Family Process Institute.

Turning a Blind Eye: Public Support of Emergency Housing Policies for Sex Offenders.

Science.gov (United States)

Socia, Kelly M; Dum, Christopher P; Rydberg, Jason

2017-07-01

In this study, we examine the influences of citizen decision making in the context of four policy scenarios that would affect the living conditions of sex offenders (SOs) residing at an "emergency shelter" budget motel. We surveyed 773 citizens in an online survey about their support for four policy scenarios that would improve the living conditions of SOs: (a) at no cost to the respondent, (b) in exchange for a US$100 tax increase, and (c) by relocating SOs within the respondent's neighborhood (i.e., "in my backyard"/IMBY scenario). The fourth scenario involved moving nearby SOs into substandard housing located far away from the respondent (i.e., "not in my backyard"/NIMBY). While prior research finds that the public overwhelmingly supports punitive SO policies, we find that indifference is a mainstay of public opinion about improving SO housing conditions. That is, we find only modest levels of average support for any of the policy scenarios, and policy support decreased when increased taxes would be involved, compared with a "no cost" scenario. While no respondent characteristics significantly predicted policy support consistently across all four scenarios, some scenarios showed stark differences in support when considering specific respondent characteristics. Overall, these results suggest that what does affect support depends on the details of the policy being proposed, as well as who is considering the policy. We end by discussing the policy implications of our study for both policymakers and the public.

The construction sector comprises a number of activities that may result in environmental impacts of considerable magnitude, waste generation being one of the major negative effects of this industry due to the large streams generated. Proper knowledge of the environmental problem caused by the sector is of great importance in order to achieve an effective waste management. Thus, this paper analyse the Spanish situation regarding construction and demolition waste (CDW) compared with other European Union countries; which sets out the current figures of the CDW scenario (legislation, generation, composition, treatment and market) as well as the difficulties encountered when handling this residue.

Demolition of one of the old barracks

CERN Multimedia

2002-01-01

Many people at CERN will no doubt remember having rented accommodation in the four barracks-type huts near Entrance A. The rates were certainly rock bottom but it was hardly the Ritz! Put up at the end of the 1950s, they were abandoned in favour of the Saint-Genis-Pouilly hostel and the Meyrin site hostels. As they no longer meet current safety standards, they will all ultimately have to be demolished. One of them, situated immediately below the HV power line, has just been demolished at the request of the Swiss electricity company Energie Ouest Suisse. With its demolition, a little piece of CERN's social history has gone for ever.

Chemical sulphate removal for treatment of construction and demolition debris leachate.

Science.gov (United States)

Kijjanapanich, Pimluck; Annachhatre, Ajit P; Esposito, Giovanni; Lens, Piet N L

2014-08-01

Construction and demolition debris (CDD) is a product of construction, renovation or demolition activities. It has a high gypsum content (52.4% of total gypsum), concentrated in the CDD sand (CDDS) fraction. To comply with the posed limit of the maximum amount of sulphate present in building sand, excess sulphate needs to be removed. In order to enable reuse of CDDS, a novel treatment process is developed based on washing of the CDDS to remove most of the gypsum, and subsequent sulphate removal from the sulphate-rich CDDS leachate. This study aims to assess chemical techniques, i.e. precipitation and adsorption, for sulphate removal from the CDDS leachate. Good sulphate removal efficiencies (up to 99.9%) from the CDDS leachate can be achieved by precipitation with barium chloride (BaCl2) and lead(II) nitrate (Pb(NO3)2). Precipitation with calcium chloride (CaCl2), calcium carbonate (CaCO3) and calcium oxide (CaO) gave less efficient sulphate removal. Adsorption of sulphate to aluminium oxide (Al2O3) yielded a 50% sulphate removal efficiency, whereas iron oxide-coated sand as adsorbent gave only poor (10%) sulphate removal efficiencies.

Predictors of senior center use among older adults in New York City public housing.

2014-12-01

Despite agreement among stakeholders that senior centers can promote physical and mental health, research on senior center use in urban populations is limited. Our objective was to describe demographic and health factors associated with senior center use among urban, low-income older adults in order to inform programming and outreach efforts. We used data from a 2009 telephone survey of 1036 adults randomly selected from rosters of New York City public housing residents aged 65 and older. We analyzed senior center use by race/ethnicity, age, gender, health, housing type, and income, and used a forward selection approach to build best-fit models predicting senior center use. Older adults of all ages and of both genders reported substantial use of senior centers, with nearly one third (31.3%) reporting use. Older adults living alone, at risk of depression, or living in specialized senior housing had the greatest use of centers. Senior center use varied by race/ethnicity, and English-speaking Hispanics had a higher prevalence of use than Spanish-speaking Hispanics (adjusted prevalence ratio [PR]=1.69, 95% CI: 1.11-2.59). Spanish-speaking communities and older adults living in non-senior congregate housing are appropriate targets for increased senior center outreach efforts.

All restaurants (61=fast food, FF; 72=table service, TS) within an 800-meter radius of 13 public housing developments (HD) and 4 comparison neighborhoods were audited using the Restaurant Assessment Tool©2010. HD neighborhoods were lower income and higher minority than comparison neighborhoods with similar density and street connectivity. Restaurants in HD neighborhoods had fewer healthy entrées than comparison neighborhoods. FF restaurants had cheaper beverages and more children's meals, supersize drinks, free prize with purchase, super-size items, special characters, and more items geared to driving than TS restaurants. Residents of lower socioeconomic neighborhoods may be differentially exposed to unhealthy food options.

High Flux Isotopes Reactor (HFIR) Cooling Towers Demolition Waste Management

Energy Technology Data Exchange (ETDEWEB)

Pudelek, R. E.; Gilbert, W. C.

2002-02-26

This paper describes the results of a joint initiative between Oak Ridge National Laboratory, operated by UT-Battelle, and Bechtel Jacobs Company, LLC (BJC) to characterize, package, transport, treat, and dispose of demolition waste from the High Flux Isotope Reactor (HFIR), Cooling Tower. The demolition and removal of waste from the site was the first critical step in the planned HFIR beryllium reflector replacement outage scheduled. The outage was scheduled to last a maximum of six months. Demolition and removal of the waste was critical because a new tower was to be constructed over the old concrete water basin. A detailed sampling and analysis plan was developed to characterize the hazardous and radiological constituents of the components of the Cooling Tower. Analyses were performed for Resource Conservation and Recovery Act (RCRA) heavy metals and semi-volatile constituents as defined by 40 CFR 261 and radiological parameters including gross alpha, gross beta, gross gamma, alpha-emitting isotopes and beta-emitting isotopes. Analysis of metals and semi-volatile constituents indicated no exceedances of regulatory limits. Analysis of radionuclides identified uranium and thorium and associated daughters. In addition 60Co, 99Tc, 226Rm, and 228Rm were identified. Most of the tower materials were determined to be low level radioactive waste. A small quantity was determined not to be radioactive, or could be decontaminated. The tower was dismantled October 2000 to January 2001 using a detailed step-by-step process to aid waste segregation and container loading. The volume of waste as packaged for treatment was approximately 1982 cubic meters (70,000 cubic feet). This volume was comprised of plastic ({approx}47%), wood ({approx}38%) and asbestos transite ({approx}14%). The remaining {approx}1% consisted of the fire protection piping (contaminated with lead-based paint) and incidental metal from conduit, nails and braces/supports, and sludge from the basin. The waste

2018-05-01

A phonon counting scheme based on the control of polaritons in an optomechanical system is proposed. This approach permits us to measure the number of phonons in a quantum non-demolition (QND) manner for arbitrary modes not limited by the frequency matching condition as in usual photon-phonon scattering detections. The performance on phonon number transfer and quantum state transfer of the counter are analyzed and simulated numerically by taking into account all relevant sources of noise.

Before it became the media focus, Yihuang event was just another ordinary occurrence of residents resisting demolition of their houses, a part of the subaltern politics. The main contention strategies taken by the families under the order to move typically including negotiation with the local government in charge of demolition, intercepting visits to appeal, and seeking media attention. These are ＂weapons of the weak＂, parochial, local-specific, and bifurcated~ therefore, of low salience and poor coordination, usually unsuccessful to achieve contention objectives. This time, the Zhong family adopted an extreme contention means of self-immolation. Since the occurrence of this event, the large-scale involvement of the media has presented the inherent tension of policies to the public, and the demolition

This programme is characterised by operating above the municipal level, and it requires a structure that has the administrative powers of an agency. As regards the quality of housing, the following equation has to be dispensed with: public residential housing = ugly building characterised by alienation and anomy. Planners from this century have been called on to rise the challenge. To be certain of obtaining finance for ERP programmes, the old road of contributions at source from workers should be pursued as well as the establishment of a single fund that gathers together all the financing foreseen by laws made over the years and not spent, set aside for ERP.

Assessment of different construction and demolition waste management approaches

Directory of Open Access Journals (Sweden)

Manal S. Abdelhamid

2014-12-01

Full Text Available The waste generated from construction and demolition sites is considered one of the most irritating problems in Egypt. In the last 10 years some effort has been made toward solving this problem, the most outstanding is the newly issued Egyptian rating system “Green Pyramids Rating System”. It emphasizes on waste management and particularly “site provision and environment” which contributes to 75% of the management category score. However the traditional practice which is limited to dumping all the generated waste is still dominating. The absence of sustainable practices in construction sector in Egypt led to the lack in financial and environmental data. From strategic perspective, the research aims at developing a detailed procedure to evaluate two construction and demolition waste management approaches by means of Decision Matrix technique. A detailed study is introduced for the two approaches; for each approach a flow chart is developed to demonstrate its lifecycle, as well as the cost break down structure and the different stakeholders’ roles. A penetration discussion of the pros and cons for each approach was developed accordingly and came out with sixteen influencing attributes for both approaches. The previous steps paved the ground to construct a Decision Matrix to decide on one of the approaches from a strategic environmentally oriented perspective. The study relied on the detailed and deep demonstration of the two approaches to justify the assigned weight for attributes and scores for corresponding approach. From a strategic perspective, the decision came out in favor of the more environmentally friendly approach.

approximately 18,580 m{sup 2} (200,000 ft{sup 2}). The initially approved baseline for the ARRA D and D Project was to remove 22 buildings and structures that included approximately 14,680 m{sup 2} (158,000 ft{sup 2}) of footprint. By employing efficiencies during subcontracting, demolition, and waste segregation, the savings allowed an additional 1,580 m{sup 2} (17,000 ft{sup 2}) of footprint to be removed using ARRA funds. Additionally, the lessons learned from this experience were used to apply NNSA funding to the removal of six additional non-contaminated buildings and structures. In the end, 29 buildings and structures, including stacks, cooling towers and tanks, were removed from the mesa. The entire DP East area was cleared of buildings and sub-grade structures and the soils cleaned to residential standards. The total footprint reduction at TA-21 as a result of this effort was in excess of 17,650 m{sup 2} (190,000 ft{sup 2}). The use of a Laboratory self-performance team to start demolition of non-contaminated structures resulted in steady work performance early in the project while subcontracts were being put in place to perform more complicated abatement and contaminated demolition activities. Most importantly, there were no serious worker injuries and the minor injuries recorded were those common to construction type activities. Extensive monitoring along the site boundary demonstrated that no hazardous chemicals or radioactive contamination were released and radiological dose to the public was negligible. The ARRA demolition activities were completed six months in advance of the deadline for employing ARRA funds. Additionally, over 17,585 m{sup 3} (23,000 yds{sup 3}) of building demolition debris was safely removed from DP Mesa. All of the major buildings have been removed, unencumbered access to the SWMUs that are required to be cleaned up by the Consent Order with the state of New Mexico, has been achieved, and a significant portion of the mesa has been prepared to

Lawania, Krishna; Sarker, Prabir; Biswas, Wahidul

2015-01-01

Western Australia’s housing sector is growing rapidly and around half a million houses are expected to be built by 2030, which not only will result in increased energy and resources demand but will have socio-economic impacts. Majority of Western Australians live in detached houses made of energy intensive clay bricks, which have a high potential to generate construction and demolition (C&D) waste. Therefore, there is a need to look into the use of alternative materials and construction methods. Due to Western Australia’s temperate climate, concrete could not only offer a comfortable living space but an operational energy saving also can be achieved. This paper has assessed the global warming implications of cast in-situ concrete sandwich wall system as an alternative to clay brick walls (CBW) with partial replacement of cement in concrete with by-products such as fly ash (FA) and ground granulated blast furnace slag (GGBFS), natural aggregate (NA) with recycled crushed aggregate (RCA), natural sand (NS) with manufactured sand (MS) and, polyethylene terephthalate (PET) foam core as a replacement to polystyrene core for construction of a typical 4 × 2 × 2 detached house in Perth. Life cycle management (LCM) approach has been used to determine global warming reduction benefits due to the use of available by-products and recycled materials in Western Australian houses.

In recent years the generation rate of construction and demolition waste (C&D) has significantly augmented. The aim of this study was to assessed the quality and quantity of construction and demolition waste in Tehran (capital of Iran). Questionnaire methods were used for estimating the amount of generated C&D wastes national statistical data and typical waste generation data. In order to defining the composition of C&D waste, trucks were randomly selected and their wastes were separated and weighted. According to obtained results, about 82,646,051 m 3 of C&D waste (average 16,529,210 m 3 per year) were generated during 2011 to 2016 which only about 26% of them has been recycled. Mixing sand and cement, concrete, broken bricks and soil have the highest amount of the composition of C&D waste in Tehran that was 30, 19, 18 and 11%, respectively. Based on the results, about 2,784,158 t of the waste will generate in 2025 and this is approximately 122% higher than wastes generate in 2016. Based on MAPSA's data, 360 teams of personnel cruise and control the illegal disposals, but due to the expansion of Tehran this number of teams is inadequate and can't be effective in controlling the situation. In general, the overall condition of C&D waste management in Tehran seems undesirable and needs to be updated based on the experience of successful countries in this field.

The proposed new demolition landfill at Test Area North on the Idaho National Engineering and Environmental Laboratory (INEEL) will support ongoing demolition and decontamination within the facilities on the north end of the INEEL. In June of 2003, the INEEL Cultural Resource Management Office conducted archival searches, field surveys, and coordination with the Shoshone-Bannock Tribes to identify all cultural resources that might be adversely affected by the project and to provide recommendations to protect those listed or eligible for listing on the National Register of Historic Places. These investigations showed that landfill construction and operation would affect two significant cultural resources. This report outlines protective measures to ensure that these effects are not adverse.

2014-07-01

African American adolescents are disproportionately represented in urban public housing developments. These neighborhoods are generally characterized by high rates of poverty, crime, violence, and disorganization. Although evidence is emerging on youths in these communities, little is known about their depressive symptoms, perceived efficacy, or frequency of substance use and sex-risk behavior. Further, even less is known about their exposure to community and household violence, their parents' behavior, or their sense of connection to their communities. Using a sample of 782 African American adolescents living in public housing neighborhoods located in four large U.S. cities, this article attempts to rectify the observed gap in knowledge by presenting a descriptive overview of their self-reported depressive symptoms; self-efficacy; frequencies of delinquent and sexual-risk behavior; and alcohol, tobacco, and other drug use. The self-reported ratings of their parents' behavior as well as their exposure to community and household violence are presented. Analytic procedures include descriptive statistics and mean comparisons between genders and across research cities. Results suggest several differences between genders and across research sites. However, results are not very different from national data. Implications for social work practice are discussed.

Full Text Available Sylvia Dominguez’s book "Getting Ahead: Social mobility, Public Housing, and Immigrant Networks" fits neatly in the tradition of Cecilia Menjivar, Pierette Hondaneu-Sotelo, Mary Romero and other recent longitudinal ethnographic studies of immigrant women’s social support networks. Dominquez attempts in this text to bridge the gap between studies of urban poverty and public housing and that of the assimilation and immigrant incorporation literatures. She notes that the "literature on social mobility among residents of high poverty neighborhoods is unproductively divided into theories to explain the experience of low income African Americans living in areas of concentrated black poverty , and less prolific literature to explain the experiences of immigrants living in similarly segregated neighborhoods."

2017-11-30

In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two different percentages (15% and 30%) of natural aggregates were substituted by recycled aggregates in the manufacture of paving blocks and hollow tiles. Dosages used by the company have not been changed by the introduction of recycled aggregate. Precast elements have been tested by means of compressive and flexural strength, water absorption, density, abrasion, and slipping resistance. The results obtained show the possibility of using these wastes at an industrial scale, satisfying the requirements of the Spanish standards for these elements.

Lampris, C; Lupo, R; Cheeseman, C R

2009-01-01

Recycling plants that size, sort and wash construction and demolition waste can produce high quality aggregate. However, they also produce up to 80ton per hour of filter cake waste containing fine (waste and normally landfilled. This research investigated the potential to form geopolymers containing silt, which would allow this problematic waste to be beneficially reused as aggregate. This would significantly improve the economic viability of recycling plants that wash wastes. Silt filter cakes have been collected from a number of aggregate washing plants operating in the UK. These were found to contain similar aluminosilicate crystalline phases. Geopolymer samples were produced using silt and silt mixed with either metakaolin or pulverised fuel ash (PFA). Silt geopolymers cured at room temperature had average 7-day compressive strengths of 18.7MPa, while partial substitution of silt by metakaolin or PFA increased average compressive strengths to 30.5 and 21.9MPa, respectively. Curing specimens for 24h at 105 degrees C resulted in a compressive strength of 39.7MPa and microstructural analysis confirmed the formation of dense materials. These strengths are in excess of those required for materials to be used as aggregate, particularly in unbound applications. The implications of this research for the management of waste silt at construction and demolition waste washing plants are discussed.

Full Text Available In major Egyptian cities there is a surge in construction and demolition waste (CDW quantities causing an adverse effect on the environment. The use of such waste as recycled aggregate in concrete can be useful for both environmental and economical aspects in the construction industry. This study discusses the possibility to replace natural coarse aggregate (NA with recycled concrete aggregate (RCA in structural concrete. An investigation into the properties of RCA is made using crushing and grading of concrete rubble collected from different demolition sites and landfill locations around Cairo. Aggregates used in the study were: natural sand, dolomite and crushed concretes obtained from different sources. A total of 50 concrete mixes forming eight groups were cast. Groups were designed to study the effect of recycled coarse aggregates quality/content, cement dosage, use of superplasticizer and silica fume. Tests were carried out for: compressive strength, splitting strength and elastic modulus. The results showed that the concrete rubble could be transformed into useful recycled aggregate and used in concrete production with properties suitable for most structural concrete applications in Egypt. A significant reduction in the properties of recycled aggregate concrete (RAC made of 100% RCA was seen when compared to natural aggregate concrete (NAC, while the properties of RAC made of a blend of 75% NA and 25% RCA showed no significant change in concrete properties.

For demolition of Ponte del Barco, the Torrente Mugnone overpass at the Parco delle Cascine of Firenze, were checked up entities in the field of energy and vibrational noise produced during activities on sensitive lens, considering the building located near the structure being demolished. The vibrations to the building have been checked with reference to noise thresholds of disturbance to the person (UNI 9614) and resentment/damage to the building (UNI 9 9 16). Evaluation of transient vibration actions on the building were examined during the demolition of the structure, carried out using excavator CAT 320 D LN equipped with concrete crusher, and handling stages of demolition material using excavator ZAX 2 40 Hitachi equipped with a shovel. The tests were conducted with Symphonie type level meter (class 1 REF. EN60651/94 and EN60804/9 4) and oriented velocimeters n. 4 recording stations using GEOBOX of Sara Electr. Instr. The noise level was compared with the acoustic limits of the area and the intensity of vibration induced on sensitive building was related to thresholds of disturbance to the person and damage to structures, ensuring that in the course of the demolition operations were the conditions of security of operators in the area and the absence of damage to the buildings. Based on the findings from the analysis, the acoustic activity of demolition of the Bridge in Florence took place within the acoustic limits of exemption of localization activities (class IV – area of intense human activity). The exceeded the thresholds of vibrational disturbance to the person was checked, in reference UNI 9614; the exceeded the thresholds for structural damage was not checked, in reference to UNI 9916. The attendance of the necessary staff for testing acoustic and vibrational did not affect any sensitive subject even in the presence of the excess of noise and vibration thresholds of disturbance to the person.

Recycling of construction and demolition waste in Kuwait

'Full text:' There is an increasing pressure on the construction industry to reduce costs and improve our environment. The fact is that both of these goals can be achieved at the same time. Although construction and demolition (C and D) constitutes a major type of waste in terms of volume and weight, its management and recycling efforts have not seen the light in Kuwait. The goal of this research project is to study methods leading to the minimization of the total C and D waste that is landfilled in Kuwait. This can be achieved by applying the waste management hierarchy in order of importance: 1) reduce, 2) re-use, 3) recycle, 4) incineration (energy recovery), and 5) safe disposal. This paper presents the current C and D waste disposal system in Kuwait and identifies potential problems to the environment, people and economy. Then, it investigates the recycling option to manage and control this major type of waste in an economically efficient and environmentally safe manner. There are significant volumes of potentially valuable and recoverable resources being wasted in the construction industry, and these figures are continuously growing as we are starting the new millennium. C and D waste constitutes 15%-30% of all solid waste entering landfills in various countries [Bossink 1995]; and thus it is a major type of waste. An estimated 2-3 million ton of construction and demolition waste are being only disposed of in Kuwait's landfill sites each year despite the limited available land (Industrial Investment Company, 1990). C and D waste is a target because it is both heavy and bulky, and therefore undesirable for disposal in engineered, lined landfills because of the space it consumes. On the other hand, many C and D materials have high potential for recovery and use. Recovering C and D waste can help communities reach their recycling goals, preserve valuable space in their local landfills, and create better opportunities for handling other kind of waste. Therefore

Sterner, H.; Leushacke, D.; Rittscher, D.

1995-01-01

The unexpected decision to decommission the plants in Greifswald makes the management and disposal of fuels and plant waste a major issue to be solved as a precondition for decommissioning and dismantling. The decisive point in waste management is the existence of an interim store or repository of sufficient capacity to accept both the nuclear fuel and the plant waste and the considerable volumes of radioactive residues arising in dismantling. Current major activities include planning for decommissioning and demolition, and drafting of the licensing documents; removal of the fuel elements from the reactor units; construction of the northern interim store for fuel elements and residues.

We examined associations of several health outcomes with green and conventional low-income housing, where the prevalence of morbidities and environmental pollutants is elevated. We used questionnaires and a visual inspection to compare sick building syndrome (SBS) symptoms and asthma-related morbidity among residents in multifamily units in Boston, Massachusetts, between March 2012 and May 2013. Follow-up was approximately 1 year later. Adults living in green units reported 1.35 (95% confidence interval [CI] = 0.66, 2.05) fewer SBS symptoms than those living in conventional (control) homes (P green homes experienced substantially lower risk of asthma symptoms (odds ratio [OR] = 0.34; 95% CI = 0.12, 1.00), asthma attacks (OR = 0.31; 95% CI = 0.11, 0.88), hospital visits (OR = 0.24; 95% CI = 0.06, 0.88), and asthma-related school absences (OR = 0.21; 95% CI = 0.06, 0.74) than children living in conventional public housing. Participants living in green homes had improved health outcomes, which remained consistent over the study period. Green housing may provide a significant value in resource-poor settings where green construction or renovation could simultaneously reduce harmful indoor exposures, promote resident health, and reduce operational costs.

Estimating construction and demolition debris generation using a materials flow analysis approach.

Cochran, K M; Townsend, T G

2010-11-01

The magnitude and composition of a region's construction and demolition (C&D) debris should be understood when developing rules, policies and strategies for managing this segment of the solid waste stream. In the US, several national estimates have been conducted using a weight-per-construction-area approximation; national estimates using alternative procedures such as those used for other segments of the solid waste stream have not been reported for C&D debris. This paper presents an evaluation of a materials flow analysis (MFA) approach for estimating C&D debris generation and composition for a large region (the US). The consumption of construction materials in the US and typical waste factors used for construction materials purchasing were used to estimate the mass of solid waste generated as a result of construction activities. Debris from demolition activities was predicted from various historical construction materials consumption data and estimates of average service lives of the materials. The MFA approach estimated that approximately 610-78 × 10(6)Mg of C&D debris was generated in 2002. This predicted mass exceeds previous estimates using other C&D debris predictive methodologies and reflects the large waste stream that exists. Copyright © 2010 Elsevier Ltd. All rights reserved.

The Juelich-1 Research Reactor (FRJ-1), also referred to as MERLIN (Medium Energy Research Light Water Moderated Industrial Nuclear Reactor), was a light-water moderated and cooled swimming pool reactor of British design. The cornerstone in the erection of the reactor building was laid on June 11, 1958. Reactor operation was started on February 23, 1962. The plant was last run at a thermal power of 10 MW and shut down for good in 1985 after 23 years of operation. After the fuel elements had been removed and most of the experimental installations dismantled, some first steps towards demolition were taken in 1995. Demolition on a large scale began in 1996. September 8, 2008 was a special day: On the area of the former reactor hall, an oak tree was planted as a symbol of the 'green field' and of the original oak wood which had to make way for the construction of reactors in Juelich. An oak tree now stands in the place of the reactor unit. Was that all? It was not, for there were ancillary systems, operations, utility and hygiene buildings which had to be pulled down. Decontamination and clearance measurements were completed. The application for clearance was prepared and completed. Conventional demolition was started in 2009. After completion of that step, the last chapter about demolition of the FRJ-1 research reactor has been written, and the book can be closed. (orig.)

Immobilization of calcium sulfate contained in demolition waste

International Nuclear Information System (INIS)

Ambroise, J.; Pera, J.

2008-01-01

This paper presents the results of a laboratory study undertaken to examine the treatment of demolition waste containing calcium sulfate by means of calcium sulfoaluminate clinker (CSA). The quantity of CSA necessary to entirely consume calcium sulfate was determined. Using infrared spectrometry analysis and X-ray diffraction, it was shown that calcium sulfate was entirely consumed when the ratio between CSA and calcium sulfate was 4. Standard sand was polluted by 4% calcium sulfate. Two solutions were investigated: ·either global treatment of sand by CSA, ·or immobilization of calcium sulfate by CSA, followed by the introduction of this milled mixture in standard sand. Regardless of the type of treatment, swelling was almost stabilized after 28 days of immersion in water

Use of engineered nanomaterials in the construction industry with specific emphasis on paints and their flows in construction and demolition waste in Switzerland.

One sector where the use of engineered nanomaterials (ENMs) is supposed to offer novel or improved functionalities is the construction industry. During the renovation or demolition of buildings, ENMs contained in former construction materials will enter recycling systems or become construction waste. Currently, information about ENM flows in these processes is insufficient. The potential for the release of ENMs from this waste into the environment is unknown, as are the environmental impacts. To evaluate whether there is currently any nano-relevant construction and demolition waste (C&DW) originating from buildings, we evaluated the sources and flows of ENMs in C&DW and identified their potential exposure pathways. A survey of business representatives of Swiss companies in this sector found that ENMs are mainly used in paints and cement. The most frequently used ENMs in the Swiss housing construction industry are nano-TiO2, nano-SiO2, nano-ZnO, and nano-Ag. Using a bottom-up, semi-quantitative approach, we estimated the flows of ENMs contained in paints along the product's life cycle from buildings to recycling and landfill. The flows of ENMs are determined by their associated flows of building materials. We estimated an annual amount of ENMs used in paints of 14t of TiO2, 12t of SiO2, 5t of ZnO, and 0.2t of Ag. The majority of ENMs contained in paints in Switzerland enter recycling systems (23t/y), a smaller amount is disposed directly in landfills (7t/y), and a tiny fraction of ENM waste is incinerated (0.01t/y). Our results allow a qualitative determination of the potential release of ENMs into technical or environmental compartments, with the highest potential release expected during recycling.

Radionuclides in house dust

1985-04-01

Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate authorising Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, although radionuclides originating rom the BNFL site can be detected in house dust, this source of contamination is a negligible route of exposure for members of the public in West Cumbria. This report presents the results of the Board's study of house dust in twenty homes in Cumbria during the spring and summer of 1984. A more intensive investigation is being carried out by Imperial College. (author)

The FRJ-1 (MERLIN) research reactor was decommissioned in 1985 after twenty-three years of operation. Demolition of the plant was begun in 1996. The article contains a survey of the demolition steps carried out so far within the framework of three partial permits. The main activity is the demolition of the reactor core structures as a precondition for subsequent measures to ensure clearance measurements of the building. The core structures are demolished which were exposed to high neutron fluxes during reactor operation and now show the highest activity and dose rate levels, except for the core internals. For demolition and disassembly of the metal structures in this part of the plant, the tools specially designed and made include a remotely operated sawing system and a pipe cutting system for internal segmentation of the beam lines. The universal demolition tool for use also above and beyond the concrete structures has been found to be a remotely controlled electrohydraulic demolition shovel. Spreading contamination in the course of the demolition work was avoided. One major reason for this success was the fact that no major airborne contamination existed at any time as a consequence of the quality of the material demolished and also of the consistent use of technical tools. While the reactor block was being demolished, an application for clearance measurement of the reactor hall and subsequent release from the scope of the Atomic Energy Act was filed as early as in mid-2003. The fourth partial permit covering these activities is expected to be issued in the spring of 2004. (orig.)

Properties of Concrete Paving Blocks and Hollow Tiles with Recycled Aggregate from Construction and Demolition Wastes

Directory of Open Access Journals (Sweden)

Carlos Rodríguez

2017-11-01

Full Text Available In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two different percentages (15% and 30% of natural aggregates were substituted by recycled aggregates in the manufacture of paving blocks and hollow tiles. Dosages used by the company have not been changed by the introduction of recycled aggregate. Precast elements have been tested by means of compressive and flexural strength, water absorption, density, abrasion, and slipping resistance. The results obtained show the possibility of using these wastes at an industrial scale, satisfying the requirements of the Spanish standards for these elements.

Objective: Our home can have a major impact on our physical and mental health; this is particularly true for older people who may spend more time at home. Older people in social (i.e., public) housing are particularly vulnerable. Housing options for older people in social housing include standard design dwellings or specially designed "sheltered housing." The most suitable housing model should be identified, with older people consulted in this process. Method: Survey of older people (aged ≥60) living in standard or sheltered social housing. Data were analyzed using descriptive and inferential statistics in SPSS Version 22. Results: Overall, 380 surveys were returned (response rate = 47.2%). All older people had similar housing needs. Those in sheltered housing were more satisfied with the physical home design and reported more positive outcomes. Older people in standard housing were less likely to have necessary adaptations to facilitate aging-in-place. Discussion: Older people in standard housing reported more disability/illnesses, are worried about the future, and felt less safe at home. However, few wanted to move, and very few viewed sheltered housing as an alternative, suggesting limited knowledge about their housing options. Future social housing designs should be flexible, that is, adaptable to the needs of the tenants over time.

Research interests in addressing construction and demolition (C and D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C and D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C and D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C and D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C and D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C and D waste management research, and this is considered a major methodology for future research in the discipline. C and D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C and D waste management has emerged as a new challenging topic.

Introduction Anecdotal evidence suggests that parents protect their children from food insecurity and its effects, but few studies have concurrently assessed food insecurity among youth and parents. The purpose of this study was to examine food insecurity and eating behaviors among an urban sample of mother-adolescent dyads. Methods Mother-adolescent dyads (n = 55) were from six public housing sites in Phoenix, Arizona who completed surveys during 2014. Multivariate mixed linear and logistic regression models assessed the relationship between mother and adolescent eating behaviors in the context of food insecurity. Results Food insecurity was prevalent with 65.4% of parents and 43.6% of adolescents reporting food insecurity; 34.5% of parents and 14.5% of adolescents reported very low food security. After adjusting for food insecurity status, parents' and adolescents' fruit, vegetable, and sugar-sweetened beverage consumption was not associated. However, significant associations were observed between mothers' and adolescents' fast food intake (β = 0.52; p insecurity given the lower prevalence of food insecurity observed among adolescents. Interventions addressing food insecurity among mothers and adolescents may want to capitalize on shared eating patterns and address issues related to binge eating and leverage site-based strengths of public housing.

Social mixing through densification? The struggle over the Little Mountain public housing complex in Vancouver

Directory of Open Access Journals (Sweden)

Rosol, Marit

2015-09-01

Full Text Available In times of peak-oil and the on-going ‘urban renaissance’ (Porter and Shaw 2009, urban densification becomes increasingly more important. Densification is promoted not only for environmental reasons – in the sense of developing more compact and thus more sustainable cities – but also, as is the case in Vancouver, in the name of ‘social mixing’. Taking the conflict over “Little Mountain” – the oldest public housing complex in the province of British Columbia, Canada – as example, the article shows the conflicts that can arise in the process of densification. Despite the protests of residents and their supporters and without any concrete plans for redevelopment, almost all of the once 224 social housing units were demolished in 2009 to make room for at least 1,400 market condos (besides the 1-for-1 replacement of the social units. The example shows that densification processes that lack social measures for securing tenure for long-time residents lead to the displacement of poorer people, and to increased socio-spatial disparities. Furthermore, densification will not alleviate the affordability crisis but intensify it, if all the additionally created housing units will be market-housing only. Based on this example, the article shows that a purported social-mix policy is mainly motivated by recapturing prime real-estate, and identifies the rhetoric of ‘social mixing’ as ‘gentrification by stealth’ (Bridge et al. 2012.

This pilot study investigates the impact of active design (AD) strategies on physical activity (PA) among adults living in two Leadership in Energy and Environmental Design (LEED) certified affordable housing developments in the South Bronx, New York. One building incorporates LEED Innovation in Design (ID) Credit: Design for Health through Increased Physical Activity. Tenants in an affordable housing building (AH) incorporating active design strategies completed PA self-assessments at their lease signing and one year later in 2015. Trained research assistants obtained body measurements. Residents of neighboring non-AD affordable housing (MCV) served as a comparison. Thirty four adults were recruited from AH and 29 from MCV, retention was 56% (n = 19) and 52% (n = 15) respectively at one year. The two groups' body mass index (BMI) and high-risk waist-to-hip ratio (WHR) were not statistically significantly different when analyzed as continuous variables, although BMI category had a greater decline at AH than at MCV (p = 0.054). There was a 31.5% increase in AH participants meeting MPA requirements and a statistically significant improvement in females (p = 0.031); while there was no change in the MCV participants overall or when stratified by gender. AH participants were significantly more likely to have reported increased stair use and less likely to have reported no change or decreased stair use than participants from MCV participants (p = 0.033). Housing has a role in individual health outcomes and behavior change, broad adoption of active design strategies in affordable housing is warranted to improve physical activity measures.

Seo, Seongwon; Hwang, Yongwoo

1999-08-01

Construction and demolition (C&D) debris is generated at the site of various construction activities. However, the amount of the debris is usually so large that it is necessary to estimate the amount of C&D debris as accurately as possible for effective waste management and control in urban areas. In this paper, an effective estimation method using a statistical model was proposed. The estimation process was composed of five steps: estimation of the life span of buildings; estimation of the floor area of buildings to be constructed and demolished; calculation of individual intensity units of C&D debris; and estimation of the future C&D debris production. This method was also applied in the city of Seoul as an actual case, and the estimated amount of C&D debris in Seoul in 2021 was approximately 24 million tons. Of this total amount, 98% was generated by demolition, and the main components of debris were concrete and brick.

2015-07-09

Five Steps to Implementing the PHA Energy Efficient Unit Turnover Package (ARIES, 2014) is a guide to prepare for the installation of energy efficient measures during a typical public housing authority unit turnover. While a PHA is cleaning, painting and readying a unit for a new resident, there is an opportunity to incorporate energy efficiency measures to further improve the unit's performance. The measures on the list are simple enough to be implemented by in-house maintenance personnel, inexpensive enough to be folded into operating expenses without needing capital budget, and fast enough to implement without substantially changing the number of days between occupancies, a critical factor for organizations where the demand for dwelling units far outweighs the supply. The following guide lays out a five step plan to implement the EE Unit Turnover Package in your PHA, from an initial Self-Assessment through to Package Implementation.

This paper describes the blasting demolition of steel tower of iron works. The steel tower had four columns, and its dimension was 17 mtimes17 m in cross section and 77.6 m height. The total weight was about 1,724 t. The 18.4 kg V-type linear shaped charge was fixed around columns with box weld structures, and initiated using 16 seismograph electric detonators. Vibration and noise were measured during blasting and collapse of the tower. In the both case, the vibration levels were between 67 and 71 dB, which were low and under 75 dB, the standard level during specific construction works of the regulation act of vibration. The noise level was 120 dB(A) at the point 200 m away from the blasting source, which was over 85 dB(A), the standard level. The collapse process of steel tower was simulated using discontinuous deformation analysis. The results agreed well with those from the actual collapse. The steel tower landed about 6 seconds after the initiation, and it took about 15 seconds to complete the collapse. Before the demolition, the 6 t parts of forefeet of two columns in the collapse direction were cut and removed by blasting. Thus, the collapse was controlled in the given direction. 5 refs., 13 figs., 2 tabs.

Composition and leaching of construction and demolition waste: inorganic elements and organic compounds.

Butera, Stefania; Christensen, Thomas H; Astrup, Thomas F

2014-07-15

Thirty-three samples of construction and demolition waste collected at 11 recycling facilities in Denmark were characterised in terms of total content and leaching of inorganic elements and presence of the persistent organic pollutants PCBs and PAHs. Samples included (i) "clean" (i.e. unmixed) concrete waste, (ii) mixed masonry and concrete, (iii) asphalt and (iv) freshly cast concrete cores; both old and newly generated construction and demolition waste was included. PCBs and PAHs were detected in all samples, generally in non-critical concentrations. Overall, PAHs were comparable to background levels in urban environments. "Old" and "new" concrete samples indicated different PCB congener profiles and the presence of PCB even in new concrete suggested that background levels in raw materials may be an issue. Significant variability in total content of trace elements, even more pronounced for leaching, was observed indicating that the number of analysed samples may be critical in relation to decisions regarding management and utilisation of the materials. Higher leaching of chromium, sulphate and chloride were observed for masonry-containing and partly carbonated samples, indicating that source segregation and management practices may be important. Generally, leaching was in compliance with available leaching limits, except for selenium, and in some cases chromium, sulphate and antimony. Copyright © 2014 Elsevier B.V. All rights reserved.

Rat sightings in New York City are associated with neighborhood sociodemographics, housing characteristics, and proximity to open public space

Full Text Available Rats are ubiquitous in urban environments and, as established reservoirs for infectious pathogens, present a control priority for public health agencies. New York City (NYC harbors one of the largest rat populations in the United States, but surprising little study has been undertaken to define rat ecology across varied features of this urban landscape. More importantly, factors that may contribute to increased encounters between rats and humans have rarely been explored. Using city-wide records of rat sightings reported to the NYC Department of Health and Mental Hygiene, this investigation sought to identify sociodemographic, housing, and physical landscape characteristics that are associated with increased rat sightings across NYC census tracts. A hierarchical Bayesian conditional autoregressive Poisson model was used to assess these associations while accounting for spatial heterogeneity in the variance. Closer proximity to both subway lines and recreational public spaces was associated with a higher concentration of rat sightings, as was a greater presence of older housing, vacant housing units, and low education among the population. Moreover, these aspects of the physical and social landscape accurately predicted rat sightings across the city. These findings have identified specific features of the NYC urban environment that may help to provide direct control targets for reducing human–rat encounters.

A hierarchical Bayesian conditional autoregressive Poisson model was used to assess these associations while accounting for spatial heterogeneity in the variance. Closer proximity to both subway lines and recreational public spaces was associated with a higher concentration of rat sightings, as was a greater presence of older housing, vacant housing units, and low education among the population. Moreover, these aspects of the physical and social landscape accurately predicted rat sightings across the city. These findings have identified specific features of the NYC urban environment that may help to provide direct control targets for reducing human-rat encounters.

Quantum non-demolition measurements of multi-qubit systems are an important tool in quantum information processing, in particular for syndrome extraction in quantum error correction. We have recently demonstrated a protocol for quantum non-demolition measurement of the parity of two beryllium ions by detection of a co-trapped calcium ion. The measurement requires a sequence of quantum gates between the three ions, using mixed-species gates between beryllium hyperfine qubits and a calcium optical qubit. Our work takes place in a multi-zone segmented trap setup in which we have demonstrated high fidelity control of both species and multi-well ion shuttling. The advantage of using two species of ion is that we can individually manipulate and read out the state of each ion species without disturbing the internal state of the other. The methods demonstrated here can be used for quantum error correcting codes as well as quantum metrology and are key ingredients for realizing a hybrid universal quantum computer based on trapped ions. Mixed-species control may also enable the investigation of new avenues in quantum simulation and quantum state control. left the group and working in a company now.

Hanford, Fernald, Savannah River, and other sites are currently reviewing technologies that can be implemented to demolish buildings in a cost-effective manner. In order to demolish a structure properly and, at the same time, minimize the amount of dust generated from a given technology, an evaluation must be conducted to choose the most appropriate dust suppression technology given site-specific conditions. Thus, the purpose of this research, which was carried out at the Hemispheric Center for Environmental Technology (HCET) at Florida International University, was to conduct an experimental study of dust aerosol abatement (dust suppression) methods as applied to nuclear D and D. This experimental study targeted the problem of dust suppression during the demolition of nuclear facilities. The resulting data were employed to assist in the development of mathematical correlations that can be applied to predict dust generation during structural demolition

New mediterranean elements in contemporary housing. The case of Barcelona

Directory of Open Access Journals (Sweden)

Vincenzo Paolo Bagnato

2012-10-01

Full Text Available In the face of increasing and differentiating the low-cost housing demand and the trend of establishing new paradigms in the contemporary housing design, the architectural investigation has replaced into its disciplinary statement the topic of housing as central question in research and design experimentation. The city of Barcelona has codified in the last years innovative modalities of public management in social housing, offering interesting points of reflection on the idea of housing and of Mediterranean quality in urban, architectural and constructive terms. The paper proposes a key to the reading on the recent experiences of social housing in Barcelona illustrating the different forms through which architecture interprets the relationship between housing and public space, between innovation and constructive tradition.

DEVELOPMENT OF PUBLIC (MUNICIPAL MANAGEMENT OF THE SPHERE OF HOUSING AND COMMUNAL SERVICES: PROBLEMS AND PROSPECTS

Directory of Open Access Journals (Sweden)

G. G. Kuznetsova

2011-01-01

Full Text Available The state, municipality, population and entrepreneurship interrelation mechanism is far from being perfect in Russian housing and communal services industry. The problem may be solved provided interests of all the above participants of the industry are balanced. Most reasonable is to provide for parallel functioning of the market and governmental and municipal bodies, all of them acting in accordance with respective legal norms. More power should be given to municipalities who are non-governmental local public self-management bodies formed to provide for proper living conditions topopulation within certain territory by asserting priority interests common for this population. Negative consequences of the monopoly status of suppliers and providers of communal services should be eradicated. Transition from the monopolistic and closed communal services market to that open and competitive should become general strategy of Russian housing and communal services industry development.

Preferences, power and policy outcomes in public policy in Iceland: The Icelandic Housing Fund fiasco 2003-2005

Directory of Open Access Journals (Sweden)

Sigurbjörg Sigurgeirsdóttir

2014-12-01

Full Text Available This research focuses on the interplay of politics, bureaucracies and markets in Iceland. It aims to explain theoretically how politics and bureaucracies operate when a coalition government makes and implements decisions in a policy environment in which decisions and their effects intersect public bureaucracies’ and markets’ boundaries. The decision to raise the limits of Housing Fund mortgages in 2003 is a case examined by agenda-setting theories in public policy. The research is based on the data from parliamentary Special Investigation reports on the collapse of the Icelandic banks and the Housing Fund as well as the author’s interviews home and abroad. The research shows that, when made, the decision ignited competition between the Housing Fund and the recently privatized banks and that between the banks themselves. The Independence Party’s attempts to delay implementation of the decision involved system change backed by an instrument designed to stem a run on the Fund. The impact of this instrument (a tax on pre-payments was incompatible with the Progressive Party’s political interests. In a hasty attempt to implement its election promises, the Progressive Party ignored the fact that the Fund was operating within a transformed financial system. The conclusions indicate that those who think long-term in politics make policies by changing system dynamics, those who think short-term change programmes. System dynamics, however, change the balance of power and influence between actors, leaving legacies which curb the government’s attempt at change, unless consolidated and sustained political authority and will are established to see changes through.

The politics of partnerships: a study of police and housing collaboration to tackle anti-social behaviour on Australian public housing estates.

Science.gov (United States)

Jacobs, Keith

2010-01-01

This paper draws on the findings from a research project on partnership arrangements between the police and housing departments on three Australian public housing estates to tackle problems associated with illicit drug activity and anti-social behaviour (ASB). The analysis focused on the setting up of the partnerships and the interactions that followed from these institutional arrangements. The assumption that informs the paper is that when studying partnerships there is a need for a more critically framed analysis. The temptation to posit "a successful model" of what partnership entails and then to judge practices in relation to this model is considerable, but it inevitably falls into the trap of constructing a narrative of partnership success or failure in terms of individual agency (that is, the degree of commitment from individuals). The analysis undertaken in this paper has therefore sought to fathom a more complex set of organizational processes. Rather than confine the discussion to issues of success and failure, the study foregrounds the subjective accounts of individuals who work within partnership and the constraints they encounter. The paper therefore makes explicit the cultural tensions within and across agencies, contestation as to the extent of the policy "problem," and the divergent perspectives on the appropriate modes of intervention.

Mild cognitive impairment (MCI) is characterized by a decrease in cognitive abilities that does not affect the ability to perform activities of daily living (ADLs). Therefore, this condition is easily overlooked. The prevalence and factors of influence for MCI in older people living in publicly managed congregate housing are currently unknown. This study investigated the prevalence and distribution of MCI in older people living in publicly managed congregate housing and assessed the correlations among quality of life (QoL), ADL, and MCI. This study applied a correlational study design. The participants were older people who met the study criteria and who lived in public housing in Wanhua District, Taipei City, Taiwan. One-on-one interviews were conducted to measure the cognitive abilities of the participants, and 299 valid samples were collected. The prevalence of MCI in older people living in publicly managed congregate housing was 16.1%. The χ test was employed to evaluate the distribution of MCI prevalence and indicated that the group with higher MCI prevalence exhibited the following characteristics: older than 81 years; married; lived in public housing for more than 20 years; cohabiting; had a history of drinking; and exhibited severe memory regression, physical disabilities, psychological distress, and low QoL. The difference between the groups achieved statistical significance (p < .05). After performing logistical regression analysis to control demographic variables, we found that QoL and ADL were critical for predicting MCI. This study confirmed that QoL and ADL correlate significantly with MCI in older people. Maintaining an open and supportive community enables older people to maintain sufficient mental activity, which has been shown to reduce MCI. These findings may provide an important reference for policy makers, educators, researchers, and community practitioners in their development of service strategies for older people.

The Eco House

Energy Technology Data Exchange (ETDEWEB)

Hobbett, A. (Leicester Ecology Trust (United Kingdom))

The Eco House is a former park keeper's lodge on the periphery of Leicester's largest public park. Taken over by Leicester Ecology Trust in 1990, the Eco House was a successor to the Trust's earlier low energy house. This has been a local authority decant house, retrofitted to show the potential for increased energy efficiency in older buildings. Many of the ideas from the earlier project were adopted by the new with a widening of its remit to include all matters of environmental concern connected with people's homes. So in addition to energy efficiency, other issues addressed include conservation of resources, wildlife, organic gardening, food production, water, environmental consumerism, recycling and health. Given that the use of energy is regarded by many environmentalists to be the single most important environmental issue today, and one which is easiest for households to address, it remains the project's dominant theme.

Solar One demolition and remediation

International Nuclear Information System (INIS)

Wallace, G.L.

1995-01-01

Solar One was designed to demonstrate the feasibility of generating electrical energy from solar power using a central receiver concept. An array of heliostats focused sunlight onto a central receiver, which superheated water to produce steam. Although Solar One was successful, the oil-based Thermal Storage System (TSS), used to store heat energy for power generation at night, was not efficient. When the TSS was demolished for the installation of a more efficient molten salt system, a major effort was made to salvage or recycle all of its equipment and materials. During TSS demolition, approximately 7 tons of aluminum shielding and 205 tons of steel were salvaged as scrap metal; 200 tons of concrete was used for erosion protection along the Mohave River banks; 150,000 gallons of oil was recycled and 100 tons of equipment was salvaged for use at other facilities. During remediation, approximately 9,000 tons of oil contaminated sand, gravel and soil was recycled into approximately 10,000 tons of asphalt concrete and used to pave a nearby 5-acre parking lot at Barstow College. This not only reduced project remediation costs, but also met environmental requirements and provided a much needed community service. Of the estimated 11,864 tons of equipment and material from the TSS, less than 1% was disposed of at a landfill

1999-01-01

During the past five years, the Sandia National Labo- ratories Decontamination, Decommissioning, Demolition, and Reuse (D3R) Program has evolved and become more focused and efficient. Historical approaches to project documentation, requirements, and drivers are discussed detailing key assumptions, oversight authority, and proj- ect approvals. Discussion of efforts to streamline the D3R project planning and preparation process include the in- corporation of the principles of graded approach, Total Quality Management, and the Observational Method (CH2MHILL April 1989).1 Process improvements were realized by clearly defining regulatory requirements for each phase of a project, establishing general guidance for the program and combining project-specific documents to eliminate redundant and unneeded information. Proc- ess improvements to cost, schedule, and quality are dis- cussed in detail for several projects

The Ellweiler uranium plant - a demolition and recycling project

Mika, S.; Rohr, T.; Seehars, R.; Feser, A.

1999-01-01

The uranium plant at Ellweiler, district of Birkenfeld, was used for the production and storage of uranium concentrates. The owner of the Ellweiler uranium plant (UAE), Gewerkschaft Brunhilde GmbH, ceased processing uranium ore and recycling in 1989 and has been in liquidation since September 1991. The State of Rhineland-Palatinate, had safety measures adopted in a first step, getting the plant into a safe state by former plant personnel. The entire plant was demolished in a second step. The contract for demolishing the former uranium plant was awarded to ABB Reaktor as the general contractor in August 1996. Demolition work was carried out between April 1997 and May 1999. A total of approx. 7900 Mg of material was disposed of. At present, recultivation measures are being carried out. (orig.) [de

Evaluation of User Satisfaction in Public Residential Housing - A Case Study in the Outskirts of Naples, Italy

Science.gov (United States)

Forte, Fabiana; Russo, Yvonne

2017-10-01

Nowadays the quality of homes and social life are two closely interacting categories which require a more careful interpretation of the users’ needs. Their opinions, expectations and “desires” have to be incorporated into both the design and evaluation processes. With specific reference to the experiences of public housing, the practice of “user satisfaction” should be increasingly incorporated during the ex-post (or monitoring) evaluation in order to verify the quality and validity of the service offered, thus activating a real co-participation of the user in the creation and improvement of the housing service. It is well-known that the principle of customer satisfaction derives from the field of marketing as a tool to evaluate how and how much the products/services offered meet the needs of the consumers. In the field of the construction industry, customer satisfaction has been incorporated into the “Post-Occupation Evaluation”, an evaluation tool of the performance of the building “in use” through the combination of objective and subjective variables expressed by the occupiers. Widely used since the 1970s in Anglo-Saxon countries, Italy is still struggling to find a systematic implementation. In this perspective, the article presents an application of the customer satisfaction method for the identification of some interventions aimed at improving the quality of a complex of public residential housing localized in Ponticelli, the second most populated district in the outskirts of the metropolitan city of Naples, in the Campania Region (Italy). Following a synthetic introduction of the theme and the explanation of the object of evaluation, the article discusses the methodology and the results, focalizing on some intervention hypotheses verified in terms of economic sustainability.

Validity of Self-Reported Tobacco Smoke Exposure among Non-Smoking Adult Public Housing Residents.

Directory of Open Access Journals (Sweden)

Shona C Fang

Full Text Available Tobacco smoke exposure (TSE in public multi-unit housing (MUH is of concern. However, the validity of self-reports for determining TSE among non-smoking residents in such housing is unclear.We analyzed data from 285 non-smoking public MUH residents living in non-smoking households in the Boston area. Participants were interviewed about personal TSE in various locations in the past 7 days and completed a diary of home TSE for 7 days. Self-reported TSE was validated against measurable saliva cotinine (lower limit of detection (LOD 0.02 ng/ml and airborne apartment nicotine (LOD 5 ng. Correlations, estimates of inter-measure agreement, and logistic regression assessed associations between self-reported TSE items and measurable cotinine and nicotine.Cotinine and nicotine levels were low in this sample (median = 0.026 ng/ml and 0.022 μg/m3, respectively. Prevalence of detectable personal TSE was 66.3% via self-report and 57.0% via measurable cotinine (median concentration among those with cotinine>LOD: 0.057 ng/ml, with poor agreement (kappa = 0.06; sensitivity = 68.9%; specificity = 37.1%. TSE in the home, car, and other peoples' homes was weakly associated with cotinine levels (Spearman correlations rs = 0.15-0.25, while TSE in public places was not associated with cotinine. Among those with airborne nicotine and daily diary data (n = 161, a smaller proportion had household TSE via self-report (41.6% compared with measurable airborne nicotine (53.4% (median concentration among those with nicotine>LOD: 0.04 μg/m3 (kappa = 0.09, sensitivity = 46.5%, specificity = 62.7%.Self-report alone was not adequate to identify individuals with TSE, as 31% with measurable cotinine and 53% with measurable nicotine did not report TSE. Self-report of TSE in private indoor spaces outside the home was most associated with measurable cotinine in this low-income non-smoking population.

Measuring buildings for sustainability: Comparing the initial and retrofit ecological footprint of a century home – The REEP House

International Nuclear Information System (INIS)

Bin, Guoshu; Parker, Paul

2012-01-01

Highlights: ► Life cycle energy, carbon and ecological footprints of a century home are studied. ► The operational impact accounts for most of the total lifecycle impact. ► Sourcing energy-intensive materials locally only reduces embodied impacts a little. ► Deep energy retrofits (80% savings) achieved substantial environmental benefits. ► The environmental payback period of major energy retrofits is less than 2 years. - Abstract: The residential sector is recognized as a major energy consumer and thus a significant contributor to climate change. Rather than focus only on current energy consumption and the associated emissions, there is a need to broaden sustainability research to include full life cycle contributions and impacts. This paper looks at houses from the perspective of the ecological footprint (EF), a well-known sustainability indicator. Exemplifying single-detached houses of the early 20th century, the century-old REEP House (downtown Kitchener, Canada), together with its high performance energy retrofits, is examined in detail. This research combines material, energy and carbon emission studies. Its scope covers the life cycle of the house, including the direct and indirect consumption of material and energy, and concomitant carbon emissions during its stages of material extraction, transportation, construction, operation, and demolition. It is revealed that the REEP House had a typical impact on the environment when it was built, and, even though the renovations to improve energy efficiency by 80% introduce additional embodied environmental impacts, they are environmentally sound activities because the environmental payback period is less than 2 years.

Long-term housing subsidies and SSI/SSDI income: Creating health-promoting contexts for families experiencing housing instability with disabilities.

Science.gov (United States)

Glendening, Zachary S; McCauley, Erin; Shinn, Marybeth; Brown, Scott R

2018-04-01

Though disability and housing instability are discussed separately in public health literature, few studies address families at their intersection. As a result, little is known about families who experience both homelessness and disability, how many receive disability benefits like SSI and SSDI, or the influence of those benefits on health-promoting outcomes like housing stability and self-sufficiency. Moreover, no previous research compares the ability of different housing and service interventions to increase disability benefit access. We examine relationships between disabilities and SSI/SSDI income reported when families enter emergency shelters and later health-promoting outcomes (housing stability and self-sufficiency) and how housing interventions affect SSI/SSDI receipt. Families in the (name removed) Study (N = 1857) were interviewed in emergency shelters, randomly offered of one of three housing interventions or usual care (i.e., no immediate referral to any intervention beyond shelter), and re-interviewed 20 months later. A third of families reported a disability at shelter entry. SSI/SSDI coverage of these families increased nearly 10% points over 20 months but never exceeded 40%. Disabilities predicted greater housing instability, food insecurity, and economic stress and less work and income. Among families reporting disabilities, SSI/SSDI receipt predicted fewer returns to emergency shelter, and more income despite less work. Offers of long-term housing subsidies increased SSI/SSDI receipt. Many families experiencing homelessness have disabilities; those receiving SSI/SSDI benefits have better housing and income outcomes. Providing families experiencing homelessness with long-term housing subsidies and SSI/SSDI could improve public health. Copyright © 2017 Elsevier Inc. All rights reserved.

Brinch, J. [Energetics, Inc., Columbia, MD (United States); Ternes, M. [Oak Ridge National Lab., TN (United States); Myers, M. [USDOE, Washington, DC (United States)

1996-07-01

A five-year initiative between the US Department of Energy (DOE) and the US Department of Housing and Urban Development (HUD) demonstrated the feasibility of improving the energy efficiency of publicly-assisted housing. Twenty-seven projects and activities undertaken during 1990--95 involved research and field demonstrations, institutional and administrative changes to HUD policies and procedures, innovative financing and leveraging of federal dollars with non-federal money, and education, training, and technical assistance. With most of the 27 projects and activities completed, the two departments have initiated a five-year deployment effort, the DOE-Energy Partnerships for Affordable Homes, to achieve energy and water savings in public and assisted housing on a large scale throughout the country. A Clearinghouse for Energy Efficiency in Public and Assisted Housing managed by the National Center for Appropriate Technology (NCAT), will offer hands-on energy assistance to housing providers to complement DOE`s assistance. This paper presents the findings of the DOE-HUD Initiative, with primary attention paid to those projects which successfully integrated energy efficiency into private and public single and multifamily housing. The paper includes examples of the publications, case-study reports, exhibits and videotapes developed during the course of the Initiative. Information on the new DOE Energy Partnerships and on the NCAT Clearinghouse is also presented. New Partnership projects with the Atlanta and Chicago Housing Authorities describe the technical assistance envisioned under the Partnership.

Dismantling radiologically burdened large components is among the most complex and difficult jobs in the demolition of nuclear installations. The technologies used and their safe operation play a key role in demolition. Dismantling highly activated components as a rule requires shielding by water. As a consequence, the techniques employed must be designed for use under water. A variety of technologies are available for these applications. One established mechanical cutting method is water abrasive suspension jet cutting (WASS). Because of the small cutting nozzle employed, this highly flexible cutting technique can be used nearly anywhere together with different guiding systems. In the course of disassembly under water of the MZFR, plasma cutting has been found to be a reliable and efficient technique for remote operation. Contact arc metal cutting is a thermal cutting technique allowing all electrically conducting materials, including those with claddings, to be cut nearly irrespective of their component geometries. The methods, technology, possible uses, and practical operation of contact arc metal cutting in the demolition of the MZFR are covered in this article. (orig.)

Collaborating with Public Housing Residents and Staff to Improve Health: A Mixed-Methods Analysis.

Science.gov (United States)

Noonan, Devon; Hartman, Ann Michelle; Briggs, Joyce; Biederman, Donna J

2017-01-01

This study described the health behaviors and barriers and facilitators of those behaviors in elderly and/or disabled residents of public housing. A mixed-methods design was used. Residents (N = 88) completed a survey with validated measures of health behaviors. A sub-sample (N = 16) participated in three focus groups. Residents scored worse than population norms on the majority of behaviors measured. Qualitative results framed in an ecological model indicated the majority of facilitators and barriers to health behaviors were perceived as occurring at the intrapersonal and interpersonal levels. Interventions to promote health should consider the unique barriers and facilitators to health behaviors among residents.

Adverse Housing Conditions and Early-Onset Delinquency.

Jackson, Dylan B; Newsome, Jamie; Lynch, Kellie R

2017-09-01

Housing constitutes an important health resource for children. Research has revealed that, when housing conditions are unfavorable, they can interfere with child health, academic performance, and cognition. Little to no research, however, has considered whether adverse housing conditions and early-onset delinquency are significantly associated with one another. This study explores the associations between structural and non-structural housing conditions and delinquent involvement during childhood. Data from the Fragile Families and Child Wellbeing Study (FFCWS) were employed in this study. Each adverse housing condition was significantly associated with early-onset delinquency. Even so, disarray and deterioration were only significantly linked to early delinquent involvement in the presence of health/safety hazards. The predicted probability of early-onset delinquency among children exposed to housing risks in the presence of health/safety hazards was nearly three times as large as the predicted probability of early-onset delinquency among children exposed only to disarray and/or deterioration, and nearly four times as large as the predicted probability of early-onset delinquency among children exposed to none of the adverse housing conditions. The findings suggest that minimizing housing-related health/safety hazards among at-risk subsets of the population may help to alleviate other important public health concerns-particularly early-onset delinquency. Addressing household health/safety hazards may represent a fruitful avenue for public health programs aimed at the prevention of early-onset delinquency. © Society for Community Research and Action 2017.

The objective of this article is to develop a computerised tool (software) that facilitates the analysis of strategies for waste management on construction sites through the use of indicators of construction and demolition waste generation. The development involved the following steps: knowledge acquisition, structuring the system, coding and system evaluation. The step of knowledge acquisition aims to provide subsidies for the representation of them through models. In the step of structuring the system, it was presented the structuring and formalisation of knowledge for the development of the system, and has two stages: the construction of the conceptual model and the subsequent instantiation of the model. The coding system aims to implement (code) the conceptual model developed in a model played by computer (digital). The results showed that the system is very useful and applicable in construction sites, helping to improve the quality of waste management, and creating a database that will support new research. © The Author(s) 2016.

Social Housing in times of crisis

Directory of Open Access Journals (Sweden)

Anna Maria Pozzo

2012-10-01

Full Text Available The consequences of the economic crisis on a social level are bringing about a series of changes in how we live and reside. Some of these transformations are destined to become structural and affect how housing is designed, to take into consideration new housing models, cultural diversity, nomadism linked to working mobility, and the ageing of the population.The provision of social housing must adapt to these transformations in society and respond to the challenge by expanding the services available to residents, in a new framework of relations between the public and private sectors.Public operators are joined by new parties such as foundations while attempting new forms of support for the private initiative, which adapts to cover a part of the requirement of the middle classes made more fragile by the crisis.

2015-01-01

New Zealand state housing includes a significant portion of problematic buildings constructed after the public housing scheme launched in 1936. Most of these houses are still uninsulated, thus, cold, draughty, mouldy, and progressively decaying; however, as they are fundamental elements of the country’s culture, society, and environment, and are built with good quality materials and sound construction, they are suitable candidates for effective energy upgrades.

Stripping in hot mix asphalt produced by aggregates from construction and demolition waste.

Science.gov (United States)

Pérez, I; Pasandín, A R; Gallego, J

2012-01-01

This paper analyses the effect of water on the durability of hot asphalt mixtures made with recycled aggregates from construction and demolition debris. Indirect tensile stress tests were carried out to evaluate stripping behaviour. The mixtures tested were fabricated with 0, 20, 40 and 60% recycled aggregates. Two types of natural aggregates were used: schist and calcite dolomite. An increase in the percentage of recycled aggregates was found to produce a decrease in the tensile stress ratio of the hot asphalt mixtures. To study this phenomenon, two and three factor analyses of variance (ANOVA) were performed with indirect tensile stress being used as the dependent variable. The factors studied were the percentage of recycled aggregates (0, 20, 40 and 60%), the moisture state (dry, wet) and the type of natural aggregate (schist, calcite). On the basis of the ANOVA results, it was found that the most important factor affecting resistance was the moisture state (dry, wet) of the specimens. The percentage of recycled aggregate also affected indirect tensile stress, especially in the dry state. The type of natural aggregate did not have a significant effect on indirect tensile stress. The hot asphalt mixture specimens made with different percentages of recycled aggregates from construction and demolition debris and of natural quarry aggregates showed poor stripping behaviour. This stripping behaviour can be related to both the poor adhesion of the recycled aggregates and the high absorption of the mortar of cement adhered to them.

Recently, we have published a book containing evidence-based public health guidelines and a practical manual for the prevention of sick house syndrome. The manual is available through the homepage of the Ministry of Health, Labour and Welfare (http://www.mhlw.go.jp/file/06-Seisakujouhou-11130500-Shokuhinanzenbu/0000155147.pdf). It is an almost completely revised version of the 2009 version. The coauthors are 13 specialists in environmental epidemiology, exposure sciences, architecture, and risk communication. Since the 1970s, health problems caused by indoor chemicals, biological pollution, poor temperature control, humidity, and others in office buildings have been recognized as sick building syndrome (SBS) in Western countries, but in Japan it was not until the 1990s that people living in new or renovated homes started to describe a variety of nonspecific subjective symptoms such as eye, nose, and throat irritation, headache, and general fatigue. These symptoms resembled SBS and were designated "sick house syndrome (SHS)." To determine the strategy for prevention of SHS, we conducted a nationwide epidemiological study in six cities from 2003-2013 by randomly sampling 5,709 newly built houses. As a result 1,479 residents in 425 households agreed to environmental monitoring for indoor aldehydes and volatile organic compounds (VOCs). After adjustment for possible risk factors, some VOCs and formaldehyde were dose-dependently shown to be significant risk factors. We also studied the dampness of the houses, fungi, allergies, and others. This book is fully based on the scientific evidence collected through these studies and other newly obtained information, especially from the aspect of architectural engineering. In addition to SHS, we included chapters on recent information about "multi-chemical sensitivity."

Comparison of leaching tests to determine and quantify the release of inorganic contaminants in demolition waste

International Nuclear Information System (INIS)

Delay, Markus; Lager, Tanja; Schulz, Horst D.; Frimmel, Fritz H.

2007-01-01

The changes in waste management policy caused by the massive generation of waste materials (e.g. construction and demolition waste material, municipal waste incineration products) has led to an increase in the reuse and recycling of waste materials. For environmental risk assessment, test procedures are necessary to examine waste materials before they can be reused. In this article, results of column and lysimeter leaching tests having been applied to inorganic compounds in a reference demolition waste material are presented. The results show a good agreement between the leaching behaviour determined with the lysimeter unit and the column units used in the laboratory. In view of less time and system requirements compared to lysimeter systems, laboratory column units can be considered as a practicable instrument to assess the time-dependent release of inorganic compounds under conditions similar to those encountered in a natural environment. The high concentrations of elements in the seepage water at the initial stage of elution are reflected by the laboratory column leaching tests. In particular, authorities or laboratories might benefit and have an easy-to-use, but nevertheless reliable, method to serve as a basis for decision-making

Innovative probabilistic risk assessment applications: barrier impairments and fracture toughness. 2. Demolition Debris and Tornado Missile Hazard During Decommissioning

International Nuclear Information System (INIS)

Calhoun, David; Shepherd, Stephen

2001-01-01

During their operating lives, nuclear power plants typically maintain a high level of control over the amount of debris that is allowed to accumulate at the plant site. Although primarily intended to reduce the potential for fire damage, some plants also rely on these controls to limit the damage that could be caused during a tornado from missiles generated from loose debris. Demolition work associated with power plant decommissioning inevitably increases the quantity of debris. When bulk commodities such as piping and electrical distribution components are demolished, they are subject to various staging, handling, and storage processes before they can be released from the site. The demolition of plant structures dramatically increases the quantity of loose steel and concrete debris. For the foreseeable future, all plants that undertake decommissioning will have spent-fuel assemblies present on the plant site during the demolition project whether the spent fuel remains stored in a spent-fuel pool or is transferred to an independent spent-fuel storage installation (ISFSI). Under present regulations, protection from tornado missiles would be required for both types of spent-fuel storage. In addition, a small proportion of decommissioning plants will have operating units in close proximity. Licensing commitments for tornado missile protection may mandate controls on the production or storage of demolition debris. This paper presents a case study of the San Onofre Nuclear Generating Station (Fig. 1). Tornado missile protection licensing commitments from three types of facilities will be in force during the decommissioning of San Onofre Unit 1 (Unit 1): 1. Unit 1, under a possession-only license; 2. an ISFSI that will eventually store spent fuel from Unit 1; 3. San Onofre Operating Unit 2 (Unit 2) and San Onofre Operating Unit 3 (Unit 3). Together, these three facilities illustrate the range of impacts that licensing commitments designed for tornado protection may

Townsend, Timothy; Tolaymat, Thabet; Leo, Kevin; Jambeck, Jenna

2004-10-01

A major product recovered from the processing and recycling of construction and demolition (C&D) debris is screened soil, also referred to as fines. A proposed reuse option for C&D debris fines is fill material, typically in construction projects as a substitute for natural soil. Waste material that is reused in a manner similar to soil must first be characterized to examine potential risks to human health and the environment. In Florida, samples of C&D debris fines from 13 C&D debris recycling facilities were characterized for 11 total and leachable heavy metal concentrations. Total metal concentration results (mg/kg) were compared to existing data on background Florida soil concentrations and to Florida's risk-based soil cleanup target levels (SCTLs). All of the detected metals were found to be elevated with respect to background. The 95% upper confidence level of arsenic from 99 samples was 3.2 mg/kg; arsenic presented the greatest limitation to reuse when compared to the SCTLs. Lead was not found to pose a major problem, likely because of the relatively new building infrastructure in Florida, which results in less demolition debris and less material impacted by lead-based paint. The results of batch leaching tests conducted using simulated rainwater (mg/l) were compared directly to risk-based groundwater levels for Florida and were found not to pose a risk using existing risk assessment policies.

Recycling of construction and demolition waste: case study in the Port of Antwerp

Construction and demolition waste (C&DW) represents one of the EU’s largest waste streams. According to the Directive 2008/98/EC on waste, at least 70 percent (by weight) of non-hazardous C&DW must be recuperated by 2020. Eurostat estimates an annual C&DW generation of 970 Mton in EU-27, representing an average value of almost 2.0 ton per inhabitant, with an average recovery rate of 47%.

Site Characterization Report ORGDP Diffusion Facilities Permanent Shutdown K-700 Power House and K-27 Switch Yard/Switch House

Energy Technology Data Exchange (ETDEWEB)

Thomas R.J., Blanchard R.D.

1988-06-13

The K-700 Power House area, initially built to supply power to the K-25 gaseous diffusion plant was shutdown and disassembled in the 1960s. This shutdown was initiated by TVA supplying economical power to the diffusion plant complex. As a result of world wide over production of enriched, reactor grade U{sup 235}, the K-27 switch yard and switch house area was placed in standby in 1985. Subsequently, as the future production requirements decreased, the cost of production increased and the separation technologies for other processes improved, the facility was permanently shutdown in December, 1987. This Site Characterization Report is a part of the FY-88 engineering Feasibility Study for placing ORGDP Gaseous Diffusion Process facilities in 'Permanent Shutdown'. It is sponsored by the Department of Energy through Virgil Lowery of Headquarters--Enrichment and through Don Cox of ORO--Enrichment Operations. The primary purpose of these building or site characterization reports is to document, quantify, and map the following potential problems: Asbestos; PCB containing fluids; Oils, coolants, and chemicals; and External contamination. With the documented quantification of the concerns (problems) the Engineering Feasibility Study will then proceed with examining the potential solutions. For this study, permanent shutdown is defined as the securing and/or conditioning of each facility to provide 20 years of safe service with minimal expenditures and, where feasible, also serving DOE's needs for long-term warehousing or other such low-risk use. The K-700 power house series of buildings were either masonry construction or a mix of masonry and wood. The power generating equipment was removed and sold as salvage in the mid 1960s but the buildings and auxiliary equipment were left intact. The nine ancillary buildings in the power house area use early in the Manhattan Project for special research projects, were left intact minus the original special equipment

Housing, energy cost, and the poor: Counteracting effects in Germany's housing allowance program

International Nuclear Information System (INIS)

Groesche, Peter

2010-01-01

Adequate housing and affordable warmth are essential human needs, the lack of which may seriously harm people's health. Germany provides an allowance to low-income households, covering the housing as well as the space heating cost, to protect people from the consequences of poor housing conditions and fuel poverty. In order to limit public expenditures, payment recipients are required to choose low-cost dwellings, with the consequence that they probably occupy flats with a poor thermal performance. Recipients might therefore exhibit a lower per-square meter rent but in turn are likely to have a higher energy consumption and energy expenditures. Using a large data set of German households, this paper demonstrates that this financially counteracting effect is of negligible magnitude.

Detuned mechanical parametric amplification as a quantum non-demolition measurement

International Nuclear Information System (INIS)

Szorkovszky, A; Bowen, W P; Clerk, A A; Doherty, A C

2014-01-01

Recently it has been demonstrated that the combination of continuous position detection with detuned parametric driving can lead to significant steady-state mechanical squeezing, far beyond the 3 dB limit normally associated with parametric driving. In this work, we show the close connection between this detuned scheme and quantum non-demolition (QND) measurement of a single mechanical quadrature. In particular, we show that applying an experimentally realistic detuned parametric drive to a cavity optomechanical system allows one to effectively realize a QND measurement despite being in the bad-cavity limit. In the limit of strong squeezing, we show that this scheme offers significant advantages over standard backaction evasion, not only by allowing operation in the weak measurement and low efficiency regimes, but also in terms of the purity of the mechanical state

Modelling process integration and its management – case of a public housing delivery organization in United Arab Emirates

Full Text Available Huge volume of project information are generated during the life cycle of an AEC projects. These project information are categorized in to technical and administrative information and managed through appropriate processes. There are many tools such as Document Management Systems, Building Information Modeling (BIM available to manage and integrate the technical information. However, the administrative information and its related processes such as the payment, status, authorization, approval etc. are not effectively managed. The current study aims to explore the administrative information management process of a local housing delivery public agency. This agency manages more than 2000 housing projects at any time of a year. The administrative processesare characterized withdelivery inconsistencies among various project participants. Though there are many commercially available process management systems, there exist limitations on the customization of the modules/ systems. Hence there is a need to develop an information management system which can integrates and manage these housing projects processes effectively. This requires the modeling of administrative processes and its interfaces among the various stakeholder processes. Hence this study aims to model the administrative processes and its related information during the life cycle of the project using IDEF0 and IDEF1X modeling. The captured processes and information interfaces are analyzed and appropriate process integration is suggested to avoid the delay in their project delivery processes. Further, the resultant model can be used for effectively managing the housing delivery projects.

Environmental assessment for the salvage/demolition of 200 West Area, 200 East Area, and 300 Area steam plants

International Nuclear Information System (INIS)

1996-10-01

This environmental assessment has been prepared to assess potential environmental impacts associated with the US Department of Energy's proposed action: the salvage/demolition of the 200 West Area, 200 East Area, and 300 Area Steam Plants and steam distribution piping. Impact information will be used by the US Department of Energy, Richland Operations Office Manager, to determine if the proposed action is a major federal action significantly affecting the quality of the human environment. If the proposed action is determined to be major and significant, an environmental impact statement will be prepared. If the proposed action is determined not to be major and significant, a Finding of No Significant Impact (FONSI) will be issued and the action can proceed. The proposed action involves the salvage and demolition of the 200 West Area, 200 East Are, and 300 Area steam plants and their associated steam distribution piping, equipment, and ancillary facilities. Activities include the salvaging and recycling of all materials, wastes, and equipment where feasible, with waste minimization efforts utilized

Hydrogen sulfide (H2S) has been identified as a principal odorous component of gaseous emissions from construction and demolition debris (C&D) landfills. Although several studies have reported the ambient concentrations of H2S near C&D landfills, few studies have quantified emission rates of H2S. One of the most widely used techniques for measuring surface gas emission rates from landfills is the flux chamber method. Flux measurements using the flux chamber were performed at five different C&D landfills from April to August, 2003. The flux rates of H2S measured in this research were between 0.192 and 1.76 mg/(m2-d).

Decontaminating agents and decontamination processes for nuclear industry and for plant demolition

International Nuclear Information System (INIS)

Henning, Klaus; Gojowczyk, Peter

2012-01-01

Decontamination of surfaces of materials in nuclear facilities or in nuclear power plants under demolition can be carried out successfully if surface treatment is performed by dipping or in an ultrasonic bath by alternating between alkaline and acid baths with intermediate rinsing in demineralized water. Decontaminating aluminium surfaces sensitive to corrosion requires further treatment in an ultrasonic bath, after the first 2 ultrasonic baths, with a weak alkaline decontaminating agent. This applies alike to components to be decontaminated for re-use and parts of materials to be disposed of. The decontamination action depends on the surfaces either being free from corrosion or else showing pronounced corrosion. (orig.)

An evaluation of the composition of soil cement bricks with construction and demolition waste - doi: 10.4025/actascitechnol.v33i2.9377

Full Text Available Sustainable development requires the existence of a production network that includes the reuse of construction waste for new materials. Current analysis investigates an optimal soil-cement composition made up of construction and demolition waste for the manufacture of pressed bricks. Soil-cement bricks were manufactured from construction and demolition wastes (CDW, A-4 classified fine sandy soil and cement CP II Z 32. Laboratory tests, comprising test compaction, optimum water content and maximum dry specific weight, consistency limits, grain size distribution and linear shrinkage, were made to characterize the materials researched. Compressive strength and absorption tests were also undertaken in different combinations of composition. Results showed that the application of CDW improved soil-cement qualities and reduced shrinkage of the material used.

Umar, M. Z.; Faslih, A.; Arsyad, M.; Sjamsu, A. S.; Kadir, I.

2017-11-01

Housing development has been pioneered through a simple home construction program to reduce the production cost. Simple housing program was developed in Kendari City. The purpose of this study is to show the principles of reducing the cost production for the type 36 homes, in Kendari City. The selected architectural objects are the lower, middle and the upper structure of type 36 house. The data collection was done by observation and in-depth discussion with construction workers. The analysis technique used in this research was a descriptive narrative analysis technique in the form of tabulation data. This study concluded that there are several principles of price reduction in the structure of public housing buildings. Quick principles exist in constructing techniques such as using cigarette packs as a foundation pad, mortar usage for rapid wall standing, and the spacing of mortars could be done manually by using two fingers on a human hand. Economic principles could be used for material matters, such as eliminating the use of gravel for concrete, the use of sand material to contain the soil, the foundation does not use sand and empty stone, and the shape of the ring beam was made using triangle reinforcement.

Shanghai housing reform. Program a burden on foreign investors.

Science.gov (United States)

Burke, F

1991-09-23

This document contains a summary of the Housing Reform Program created in Shanghai, China, in 1991, which requires monthly contributions of all employers and employees in Shanghai to a "Collective Reserve Fund." The program also applies to foreign investment enterprises and must be followed by all enterprises, regardless of any previous housing benefits that an enterprise may be providing its employees. Employers must deduct 5% from each employee's salary (with a minimum) monthly and must match that amount. The total is paid into an account in the employer's name with the People's Construction Bank of China. The total amount collected and matched for an employee is considered the property of the employee, but the account is administered by the employer as a collective trust account. Each employee's balance may be withdrawn upon retirement, leaving the area, or purchasing a home and leaving state-owned housing. Foreign investment enterprises contribute a reduced amount in recognition of the fact that they pay salaries that are higher than those of state enterprises. The Housing Reform Program also requires employers to contribute to doubled rent subsidies for public housing, requires workers to purchase housing construction bonds in order to be eligible for newly allocated public housing, calles for housing to be sold at favorable prices, and creates a system whereby mortgages can be obtained from the Collective Reserve Fund.

Kartam, Nabil; Al-Mutairi, Nayef; Al-Ghusain, Ibrahim; Al-Humoud, Jasem

2004-01-01

There is an increasing pressure on the construction industry to reduce costs and improve the quality of our environment. The fact is that both of these goals can be achieved at the same time. Although construction and demolition (C&D) constitutes a major source of waste in terms of volume and weight, its management and recycling efforts have not yet seen the light in Kuwait. This study focuses on recycling efforts leading to the minimization of the total C&D waste that is currently landfilled in Kuwait. This paper presents the current status of C&D waste disposal system in Kuwait and identifies the potential problems to the environment, people and economy. Then, it investigates alternative solutions to manage and control this major type of waste in an economically efficient and environmentally safe manner. Next, the paper describes the feasibility of establishing a C&D waste recycling facility in Kuwait. It concludes by highlighting the major benefits and bottleneck problems with such a recycling facility.

Hexabromocyclododecane (HBCDD), as one of the most widely used brominated flame retardants (BFRs), is of great concern globally because of its persistence in the environment and negative impacts on humans and animals. HBCDD has been mainly used in flame-retarded expanded (EPS) and extruded (XPS) polystyrene foams for insulation in the construction industry. Most of these products will become a part of the construction and demolition (C&D) waste at the end of their life cycle (30-50 years) which is typically disposed of into landfills or incineration. However, the recycling of this material takes quite a low share compared with landfill and incineration. Consequently, high environmental risks will exist in these disposal approaches due to the HBCDD in C&D waste. Currently, XPS or EPS products containing HBCDD in the construction industry have not reached the end of their life cycle in most countries. Relatively little attention has been paid to this emergency issue by either the government or public. Furthermore, C&D waste is most likely disposed of by direct dumping, simple stacking, or open burning in developing countries. Therefore, this paper highlights the global environmental risks of HBCDD from C&D waste. Areas of research for key problems of HBCDD contained in C&D waste are suggested to help control and finally eliminate the impact.

Sustainable construction: construction and demolition waste reconsidered.

Construction activity in Europe has increased substantially in the past decade. Likewise, there has also been a commensurate rise in the generation of construction and demolition waste (C&DW). This, together with the fact that in many European countries the rate of recycling and reuse of C&DW is still quite low has engendered a serious environmental problem and a motivation to develop strategies and management plans to solve it. Due to its composition, there is a significant potential to reuse and/or recycle C&DW, and thereby, contribute to improving the sustainability of construction and development, but practical procedures are not yet widely known or practiced in the construction industry. This article (a) summarizes the different applications that are presently practiced to optimize the recovery and/or application of C&DW for reuse, and (b) proposes various measures and strategies to improve the processing of this waste. The authors suggest that to enhance environmental effectiveness, a conscious and comprehensive C&DW management plan should be implemented in each jurisdiction. More precisely, this study presents a holistic approach towards C&DW management, through which environmental benefits can be achieved through the application of new construction methods that can contribute to sustainable growth.

Simulation of construction and demolition waste leachate

Energy Technology Data Exchange (ETDEWEB)

Townsend, T.G.; Jang, Y.; Thurn, L.G.

1999-11-01

Solid waste produced from construction and demolition (C and D) activities is typically disposed of in unlined landfills. Knowledge of C{ampersand}D debris landfill leachate is limited in comparison to other types of wastes. A laboratory study was performed to examine leachate resulting from simulated rainfall infiltrating a mixed C and D waste stream consisting of common construction materials (e.g., concrete, wood, drywall). Lysimeters (leaching columns) filled with the mixed C and D waste were operated under flooded and unsaturated conditions. Leachate constituent concentrations in the leachate from specific waste components were also examined. Leachate samples were collected and analyzed for a number of conventional water quality parameters including pH, alkalinity, total organic carbon, total dissolved solids, and sulfate. In experiments with the mixed C and D waste, high concentrations of total dissolved solids (TDS) and sulfate were detected in the leachate. C and D leachates produced as a result of unsaturated conditions exhibited TDS concentrations in the range of 570--2,200 mg/L. The major contributor to the TDS was sulfate, which ranged in concentration between 280 and 930 mg/L. The concentrations of sulfate in the leachate exceeded the sulfate secondary drinking water standard of 250 mg/L.

The connection between housing and health is well established. Physical, chemical, and biological aspects of the child's home, such as cleanliness, moisture, pests, noise, accessibility, injury risks, and other forms of housing environmental quality, all have the potential to influence multiple aspects of the health and development of children. Basic sanitation, reduced household crowding, other improvements in housing and expanded, and improved housing regulations have led to advances in children's health. For example, lead poisoning prevention policies have profoundly reduced childhood lead exposure in the United States. This and many other successes highlight the health benefits for families, particularly children, by targeting interventions that reduce or eliminate harmful exposures in the home. Additionally, parental mental health problems, food insecurity, domestic violence, and the presence of guns in children's homes all are largely experienced by children in their homes, which are not as yet considered part of the Healthy Homes agenda. There is a large movement and now a regulatory structure being put in place for healthy housing, which is becoming closely wedded with environmental health, public health, and the practice of pediatrics. The importance of homes in children's lives, history of healthy homes, asthma, and exposures to lead, carbon monoxide, secondhand/thirdhand smoke, radon, allergy triggers is discussed, as well as how changes in ambient temperature, increased humidity, poor ventilation, water quality, infectious diseases, housing structure, guns, electronic media, family structure, and domestic violence all affect children's health.

Exposure to secondhand smoke is problematic for residents living in multiunit housing, as the smoke migrates through shared ventilation systems, unsealed cracks, and door spaces. The objective of our research was to assess resident exposure to secondhand smoke, support for no-smoking policies, and the health impacts of no-smoking policies in multiunit housing. Surveys of 312 heads of households who resided in 1 of 3 multiunit buildings managed by a Colorado public housing authority were administered before and after implementation of a no-smoking policy that prohibited smoking in all resident apartments and all indoor common areas. A matched-pairs analysis of initial surveys and 15-month post-policy implementation surveys for 115 respondents was conducted. Decreases were found in the number and percentage of smokers who smoked every day and the number of cigarettes smoked per day, and 30% had quit smoking 15 months after policy implementation. The percentage of residents who smelled secondhand smoke indoors declined significantly. A significant decrease in breathing problems was found after policy implementation. Although decreases were found in the incidence of asthma attacks, emphysema/chronic obstructive pulmonary disease, eye irritation, colds, nasal congestion, and ear/sinus infections, these decreases were not significant. Consistent findings across nearly all variables tested suggest that no-smoking policies reduce resident exposure to secondhand smoke, lower the incidence of secondhand smoke-associated breathing problems, decrease daily smoking and cigarette consumption, encourage smoking cessation, and increase quit attempts. If implemented in all multiunit housing, these policies could reduce exposure to secondhand smoke and health problems associated with secondhand smoke, promote smoking cessation, and reduce cigarette consumption.

Chisholm, Elinor; O'Sullivan, Kimberley

2017-11-21

While increasingly used for research, Twitter remains largely untapped as a source of data about housing. We explore the growth of social media and use of Twitter in health and social research, and question why housing researchers have avoided using Twitter to explore housing issues to date. We use the #characterbuildings campaign, initiated by an online media platform in New Zealand in 2014 to illustrate that Twitter can provide insights into housing as a public health and social problem. We find that Twitter users share details of problems with past and present homes on this public platform, and that this readily available data can contribute to the case for improving building quality as a means of promoting public health. Moreover, the way people responded to the request to share details about their housing experiences provides insight into how New Zealanders conceive of housing problems.

Quantifying construction and demolition waste: an analytical review.

Science.gov (United States)

Wu, Zezhou; Yu, Ann T W; Shen, Liyin; Liu, Guiwen

2014-09-01

Quantifying construction and demolition (C&D) waste generation is regarded as a prerequisite for the implementation of successful waste management. In literature, various methods have been employed to quantify the C&D waste generation at both regional and project levels. However, an integrated review that systemically describes and analyses all the existing methods has yet to be conducted. To bridge this research gap, an analytical review is conducted. Fifty-seven papers are retrieved based on a set of rigorous procedures. The characteristics of the selected papers are classified according to the following criteria - waste generation activity, estimation level and quantification methodology. Six categories of existing C&D waste quantification methodologies are identified, including site visit method, waste generation rate method, lifetime analysis method, classification system accumulation method, variables modelling method and other particular methods. A critical comparison of the identified methods is given according to their characteristics and implementation constraints. Moreover, a decision tree is proposed for aiding the selection of the most appropriate quantification method in different scenarios. Based on the analytical review, limitations of previous studies and recommendations of potential future research directions are further suggested. Copyright © 2014 Elsevier Ltd. All rights reserved.

A Comparative Study of Entrance in Traditional and Contemporary Houses of Iran

Directory of Open Access Journals (Sweden)

Ramin Dehbandi

2017-12-01

Full Text Available In contemporary houses in Iran, because of changes in the methods of designing and building houses, importance of entrance reduced to such level that now in contemporary houses entrance is just a door. Entrance correlates indoor safe space of house and outdoors. It`s importance lays in controlling entry, exit, territory and hierarchy. Since house owners were satisfied with traditional form of entrance, it is a good idea to learn from them in designing new entrances. The purpose of this research is to find a way for designing appropriate entrances for Iranian contemporary houses. To do this at first 40 traditional houses and 40 contemporary houses in Isfahan and Kashan were selected. These two cities are from margin of desert and the origin of traditional houses of Iran. Analysis showed that blockage of visual and phonic relation, creating a space between outdoor public space and indoor private space, creating access patterns to internal spaces and traits that separate in and out were the most significant properties of traditional entrances. All these traits are ignored in contemporary entrances. Suggestions made for design include creating public meeting space in yard and creating a separate entrance space for each house in apartments.

Intervention programs that change environments have the potential for greater population impact on obesity compared to individual-level programs. We began a cluster randomized, multi-component multi-level intervention to improve weight, diet, and physical activity among low-socioeconomic status public housing residents. Here we describe the rationale, intervention design, and baseline survey data. After approaching 12 developments, ten were randomized to intervention (n=5) or assessment-only control (n=5). All residents in intervention developments are welcome to attend any intervention component: health screenings, mobile food bus, walking groups, cooking demonstrations, and a social media campaign; all of which are facilitated by community health workers who are residents trained in health outreach. To evaluate weight and behavioral outcomes, a subgroup of female residents and their daughters age 8-15 were recruited into an evaluation cohort. In total, 211 households completed the survey (RR=46.44%). Respondents were Latino (63%), Black (24%), and had ≤ high school education (64%). Respondents reported ≤2 servings of fruits & vegetables/day (62%), visiting fast food restaurants 1+ times/week (32%), and drinking soft drinks daily or more (27%). The only difference between randomized groups was race/ethnicity, with more Black residents in the intervention vs. control group (28% vs. 19%, p=0.0146). Among low-socioeconomic status urban public housing residents, we successfully recruited and randomized families into a multi-level intervention targeting obesity. If successful, this intervention model could be adopted in other public housing developments or entities that also employ community health workers, such as food assistance programs or hospitals.

Rogers, Courtney; Johnson, Joy; Nueslein, Brianne; Edmunds, David; Valdez, Rupa S

2018-03-12

As chronic conditions are on the rise in the USA, management initiatives outside of the inpatient setting should be explored to reduce associated cost and access disparities. Chronic conditions disproportionately affect African American public housing residents due to the effects of historical marginalization on the manifestation of economic and social problems exacerbating health disparities and outcomes. Informed by participatory research action tenets, this study focused on identifying the challenges to management of chronic conditions and developing community-envisioned initiatives to address these challenges in a predominantly African American public housing community. Two focus groups were conducted with former and current public housing residents and were analyzed using inductive content analysis. Physical activity, the cost associated with healthy eating, and lack of information were noted as challenges to chronic disease management. Initiatives discussed were the formation of a walking partner's program to promote physical activity, a shopper's club to exchange coupons and learn how to prepare healthy meals, and a natural remedy's book to share information intergenerationally about management tactics. Challenges identified existed predominantly on the individual and the system level, while the initiatives generated target engaging interpersonal and community relationships. These community-envisioned approaches should be explored to facilitate chronic disease management in public housing neighborhoods.

Responding To Changes in the Decommissioning Plans for Demolition of a Former Active Handling Building at The United Kingdom Atomic Energy Establishment Winfrith

Brown, N.; Parkinson, S.J.; Cornell, R.M.; Staples, A.T.

2006-01-01

The full decommissioning of the former Active Handling Building A59 at Winfrith in Dorset is being carried out by RWE NUKEM Limited under contract from the site owners and nuclear site licence holder, United Kingdom Atomic Energy Authority (UKAEA). Following recent government changes, the United Kingdom's Nuclear Decommissioning Authority (NDA) has now set up contracts with UKAEA for delivery of the site clean-up programme. The building contains two heavily shielded suites of caves originally used to carry out remote examination of irradiated nuclear fuel elements together with other supporting facilities. The original intention was to demolish the caves ahead of the building but after detailed consideration it was concluded that demolition of the building in advance of the caves was more operationally effective. As a result, the original decommissioning plan had to be reworked to reflect these changes. The paper briefly explains how this situation arose and the means by which the problems experienced were overcome by a complete revision to the decommissioning programme. The updated plan has been adopted by UKAEA and work is now proceeding apace to clear the building of redundant items, to complete decontamination of all remaining areas and facilities and to carry out detailed radiological surveys to confirm that the building structure is clean and ready for demolition. Both cave lines have been completely decontaminated to low residual levels of activity and are essentially ready for controlled demolition. This paper describes some of the significant tasks undertaken during the past year with particular reference to the decommissioning techniques that gave the greatest success and the limitations of others originally considered. Some of these processes were aimed at minimising the volume of low level waste (LLW) generated by using standard off-the-shelf equipment to remove contamination from ∼5 Ton concrete blocks recovered from both cave line structures.

Wang, Chuan; Wu, Jian-Zhi; Zhang, Fu-Shen

2013-01-01

The disposal of construction and demolition (C&D) waste has become a serious problem in China due to the rapid increase of Chinese construction industry in recent years. In the present study, typical C&D waste was employed for ceramsite fabrication so as to find a new way for its effective recycling. A novel process was developed for manufacturing high-quality porous ceramsite according to the special chemical composition and properties of C&D waste. Most importantly, a unique bloating agent was developed for the porous structure formation since it was difficult to obtain a suitable porous structure using traditional bloating agents. The effects of processing parameters such as sintering temperature, heating rate and soaking time were investigated, and the bloating mechanism for ceramsite was discussed. The C&D waste ceramsite (CDWC), with high-intensity, low density and homogeneous mechanical properties, was much more suitable for application in the construction field. This study provides a practical process for efficient recycling of the rapidly increasing quantities of C&D waste.

Air Dispersion Modeling for Building 3026C/D Demolition

Energy Technology Data Exchange (ETDEWEB)

Ward, Richard C [ORNL; Sjoreen, Andrea L [ORNL; Eckerman, Keith F [ORNL

2010-06-01

This report presents estimates of dispersion coefficients and effective dose for potential air dispersion scenarios of uncontrolled releases from Oak Ridge National Laboratory (ORNL) buildings 3026C, 3026D, and 3140 prior to or during the demolition of the 3026 Complex. The Environmental Protection Agency (EPA) AERMOD system1-6 was used to compute these estimates. AERMOD stands for AERMIC Model, where AERMIC is the American Meteorological Society-EPA Regulatory Model Improvement Committee. Five source locations (three in building 3026D and one each in building 3026C and the filter house 3140) and associated source characteristics were determined with the customer. In addition, the area of study was determined and building footprints and intake locations of air-handling systems were obtained. In addition to the air intakes, receptor sites consisting of ground level locations on four polar grids (50 m, 100 m, 200 m, and 500 m) and two intersecting lines of points (50 m separation), corresponding to sidewalks along Central Avenue and Fifth Street. Three years of meteorological data (2006 2008) were used each consisting of three datasets: 1) National Weather Service data; 2) upper air data for the Knoxville-Oak Ridge area; and 3) local weather data from Tower C (10 m, 30 m and 100 m) on the ORNL reservation. Annual average air concentration, highest 1 h average and highest 3 h average air concentrations were computed using AERMOD for the five source locations for the three years of meteorological data. The highest 1 h average air concentrations were converted to dispersion coefficients to characterize the atmospheric dispersion as the customer was interested in the most significant response and the highest 1 h average data reflects the best time-averaged values available from the AERMOD code. Results are presented in tabular and graphical form. The results for dose were obtained using radionuclide activities for each of the buildings provided by the customer.7

Orange Houses and Tape Babies Temporary and Nebulous Art in Urban Spaces

Directory of Open Access Journals (Sweden)

Carmen L. McClish

2010-12-01

Full Text Available This essay argues that the disruption of the routine ways we engage with our cities is necessary for democratic activity and public participation. Building on research that examines the relationship between public spaces and democratic action, I explore temporary forms of creative street installation as interrupting the market-ing pleas that have become the only authorized forms of visual art in our cities. I argue that tactics in urban spaces that are temporary and provide nebulous mean-ings are necessary to grab our attention and make us linger. I propose that these forms of engagement act in the same way as people performing or playing in pub-lic spaces. I specifically employ Yi-Fu Tuan’s theoretical notions of space and movement and Margaret Kohn’s discussion of the significance of presence in pub-lic spaces to examine the creative ways we engage with and experience our cities. I examine two activist/artist projects: Mark Jenkins’ tape installations and Detroit Demolition. My analysis of these two sites demonstrates the importance of citi-zens engaging in their urban spaces. By creating temporary artwork that is nebul-ous in meaning, activists/artists are interrupting the routine ways we experience our cities.

Refurbishment of Social housing: a survey of the building stock owned by ATC Torino

Directory of Open Access Journals (Sweden)

Andrea Levra Levron

2016-11-01

Full Text Available The Italian public housing building stock is considerable, although quantitatively less than that of other European countries,. The public policies adopted in the last decades have pushed the supply of housing by the private sector and supported the sale of the assets by the public housing authorities. Those buildings are often degraded and obsolete. Nevertheless, the issue of redevelopment of this part of the residential building stock is a central focus, also because of its important social role, especially in the current period of crisis. One of the recurring factors in the Italian case is the low quality of this building stock due to the lack of an organic maintenance activity. The paper reports the first results of a research carried out by the Department of Architecture and Design in cooperation with a social housing public authority, the Regional Agency for the Central Piedmont House (ATC. The goal of the research was the development of methodologies for estimating and analysis of maintenance requirements. Moreover, the study suggests and develops a forecasting tool for the planning of maintenance operations and redevelopment of the large building estates.

Low hanging fruit? Regulations and energy efficiency in subsidized multifamily housing

International Nuclear Information System (INIS)

Reina, Vincent J.; Kontokosta, Constantine

2017-01-01

The U.S. government has invested in multifamily housing through an array of subsidized housing programs. These programs provide a venue for understanding how regulations governing multifamily housing can affect an owner's incentive to make energy efficient investments, and a tenant's desire to reduce their energy consumption levels. This paper empirically tests the impact of subsidized housing regulations on the energy efficiency of multi-family housing for low-income households. We begin by constructing a unique database that integrates actual energy use with physical, socioeconomic, and regulatory characteristics of all large multifamily properties in New York City, focusing on whether a property receives a federal rental subsidy. We employ multivariate regression models to examine the factors that influence energy consumption in multi-family buildings and compare subsidized housing to market-rate housing, controlling for a range of building and household characteristics. We find that subsidized properties are associated with higher energy consumption than similar market-rate properties and, of the subsidized housing programs, Public Housing tends to consume the most energy. Our results suggest that despite the potential for retrofitting multifamily properties, and associated cost, energy, and carbon emissions savings, regulatory factors constrain investment and consumption decisions in the case of subsidized properties. Reducing energy use in subsidized housing, therefore, rests on modifying existing regulations. - Highlights: • Developed a framework for why regulations affect utility consumption incentives. • Created and employed a dataset of actual energy use for all large properties in NYC. • Found that subsidized properties are associated with higher utility consumption. • Find that Public Housing tends to consume the most energy of the subsidy programs. • Find that regulatory factors affect investment and consumption decisions.

The Opportunistic House for Tehran: A Design Prototype

Directory of Open Access Journals (Sweden)

Sara Khorshidifard

2015-12-01

Full Text Available This article is an advocacy research for Tehran, promoting an implication of architectural design as a tool for citizen empowerment and positive environmental change. In the article, I am offering a fresh look at Tehran’s housing problems by speculating an “opportunistic house” typology as a residential style that would serve much more than just shelter. I am making a case for a new house prototype that applies socially-equitable solutions in design. My study finds applications and significance beyond plain housing design and, mainly, onto the design of ad hoc urban public realm spaces. This is in accord with my overarching mission of supporting new way of thinking about, and ultimately offering, welcoming, safe, and energized places for Tehran’s citizens. These will additionally have important implications for inhospitable public spaces worldwide. This research is grounded in my prior, multidisciplinary doctoral studies. The article itself is an initial step in my ongoing research design, of helping to build and revitalize a wide range of urban communities by nurturing their relationship to their built and natural environments. The article is a discussion around the following questions. How can housing design inventions empower citizens? In what manner can design offer progressive living place options whose services go beyond shelter needs? Particularly, in what ways can domestic spaces be designed to also embody other-than-living capacities, for example, for new kinds of public spaces? And eventually, what could a prototype of the opportunistic house look like in the context of a city like Tehran? The article is structured to first present a brief survey of how Tehran house forms and functions have developed historically, with more emphasis on their current state. It will then offer examples of opportunistic uses of domestic spaces in Tehran. This notion is communicated through narrative analysis and photographic vignettes from a few

Achieving affordable housing through energy efficiency strategy

International Nuclear Information System (INIS)

Copiello, Sergio

2015-01-01

Cooperation between public and private sector has achieved a remarkable widespread, in the Italian context, over the last two decades. Nevertheless, the increasing difficulty in accessing the capital market and the rising cost of funding sources, both noticeable over the past few years, led to a slowdown of Public–Private Partnership (PPP) initiatives. Meanwhile, the community is expressing new needs to be satisfied, such as the conversion of brownfields, the recovery of housing stock dating back to former times, as well as the refurbishment of public offices or schools. Emerging priorities include the supply of affordable dwellings for low to medium income households. This essay aims to examine a case study in which PPP and buildings energy efficiency have been successfully combined, in order to jointly contribute to the achievement of a social housing settlement. Thanks to energy efficiency measures—concerning building envelope insulation, heating system and other installations—the agreed rent results far higher than social rent of protected tenancies, and furthermore above the range of fair rents characterising other regulated tenancies, but mildly lower than market rents.

Street-involved youth (SIY) carry a disproportionate burden of sexually transmitted diseases (STD). Studies among adults suggest that improving housing stability may be an effective primary prevention strategy for improving sexual health. Housing options available to SIY offer varying degrees of stability and adult supervision. This study investigated whether housing options offering more stability and adult supervision are associated with fewer STD and related risk behaviors among SIY. A cross-sectional study was performed using public health survey and laboratory data collected from Toronto SIY in 2010. Three exposure categories were defined a priori based on housing situation: (1) stable and supervised housing, (2) stable and unsupervised housing, and (3) unstable and unsupervised housing. Multivariate logistic regression was used to test the association between housing category and current or recent STD. Secondary analyses were performed using the following secondary outcomes: blood-borne infection, recent binge-drinking, and recent high-risk sexual behavior. The final analysis included 184 SIY. Of these, 28.8 % had a current or recent STD. Housing situation was stable and supervised for 12.5 %, stable and unsupervised for 46.2 %, and unstable and unsupervised for 41.3 %. Compared to stable and supervised housing, there was no significant association between current or recent STD among stable and unsupervised housing or unstable and unsupervised housing. There was no significant association between housing category and risk of blood-borne infection, binge-drinking, or high-risk sexual behavior. Although we did not demonstrate a significant association between stable and supervised housing and lower STD risk, our incorporation of both housing stability and adult supervision into a priori defined exposure groups may inform future studies of housing-related prevention strategies among SIY. Multi-modal interventions beyond housing alone may also be required to

Taylor, Harry Owen; Wang, Yi; Morrow-Howell, Nancy

2018-05-23

There are many studies on loneliness among community-dwelling older adults; however, there is limited research examining the extent and correlates of loneliness among older adults who reside in senior housing communities. This study examines the extent and correlates of loneliness in three public senior housing communities in the St. Louis area. Data for this project was collected with survey questionnaires with a total sample size of 148 respondents. Loneliness was measured using the Hughes 3-item loneliness scale. Additionally, the questionnaire contained measures on socio-demographics, health/mental health, social engagement, and social support. Missing data for the hierarchical multivariate regression models were imputed using multiple imputation methods. Results showed approximately 30.8% of the sample was not lonely, 42.7% was moderately lonely, and 26.6% was severely lonely. In the multivariate analyses, loneliness was primarily associated with depressive symptoms. Contrary to popular opinion, our study found the prevalence of loneliness was high in senior housing communities. Nevertheless, senior housing communities could be ideal locations for reducing loneliness among older adults. Interventions should focus on concomitantly addressing both an individual's loneliness and mental health.

Staunton, John A; Mc Donnell, Rory J; Gormally, Michael J; Williams, Chris D; Henry, Tiernan; Morrison, Liam

2014-11-01

Large quantities of construction and demolition waste (C&D) are produced globally every year, with little known about potential environmental impacts. In the present study, the slug, Deroceras reticulatum (Mollusca: Gastropoda) was used as the first biomonitor of metals (Ag, As, Ba, Cd, Co, Cr, Cu, Mn, Mo, Ni, Pb, Sb, Se, Ti, Tl, V and Zn) on wetlands post infilling with construction and demolition (C&D) waste. The bioaccumulation of As, Ba, Cd, Co, Sb, Se and Tl were found to be significantly elevated in slugs collected on C&D waste when compared to unimproved pastures (control sites), while Mo, Se and Sr had significantly higher concentrations in slugs collected on C&D waste when compared to known contaminated sites (mining locations), indicating the potential hazardous nature of C&D waste to biota. Identifying exact sources for these metals within the waste can be problematic, due to its heterogenic nature. Biomonitors are a useful tool for future monitoring and impact studies, facilitating policy makers and regulations in other countries regarding C&D waste infill. In addition, improving separation of C&D waste to allow increased reuse and recycling is likely to be effective in reducing the volume of waste being used as infill, subsequently decreasing potential metal contamination.

Self-sufficiency type houses are outlined. On condition that people gain a certain amount of income in relation with the society, they self-suffice under the given environment, allowing themselves to accept a minimum of industrial products with small environmental load. Ordinary supply from outside of fossil energy and materials which depend on it is minimized. Types are classified into three: energy, energy materials and perfect self-sufficiency. A study project for environment symbiotic houses is progressing which is planned by the Ministry of Construction and Institute of Building Energy Conservation and is invested by a private company. Its target is making a house for halving an environmental load by CO{sub 2}, for the purpose of creating the environment symbiotic house which is nice to and in harmony with the global environment and human beings. As a part of the studies on energy-saving and resource conservation on houses, introduced is a plan of an autonomous house at Izu-Atagawa. The passive method and high thermal-insulation are used for air conditioning, and hot spring water for hot water supply. Electric power is generated by hydroelectric power generation using mountain streams and by solar cells. Staple food is purchased, while subsidiary food is sufficed. 17 refs., 4 figs., 1 tab.

The Association Between Social Capital and Depression Among Chinese Older Adults Living in Public Housing.

Science.gov (United States)

Wu, Tat Leong; Hall, Brian J; Canham, Sarah L; Lam, Agnes Iok Fong

2016-10-01

Social capital is a critical resource for physical and mental health among older adults, but few studies have investigated this relationship in Chinese populations, and specifically among those with low socioeconomic status. This study examined the association between depression and cognitive social capital (reciprocity and trust) and structural social capital (social participation) in a community sample of older adults living in public housing in Macau (SAR), China (N = 366). Multivariable linear regressions estimated the associations between dimensions of social capital and depression, while adjusting for potential confounders. Significant inverse associations were found between reciprocity and trust and depression. No association was found between social participation and depression. Poor self-reported health was a robust correlate of depression in all models tested. Future studies are needed to evaluate whether enhancing social capital may reduce depression among Chinese older adults living in poverty.

Bravo, Miguel; Santos Silva, António; de Brito, Jorge; Evangelista, Luís

2016-02-01

This paper intends to analyze the microstructure of concrete with recycled aggregates (RA) from construction and demolition waste from various Portuguese recycling plants. To that effect, several scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses were performed. Various concrete mixes were evaluated in order to analyze the influence of the RA's collection point and consequently of their composition on the mixes' characteristics. Afterward all the mixes were subjected to the capillary water absorption test in order to quantitatively evaluate their porosity. Results from the SEM/EDS analysis were compared with those from capillary water absorption test. The SEM/EDS analysis showed that the bond capacity of aggregates to the new cement paste is greatly influenced by the RA's nature. On the other hand, there was an increase in porosity with the incorporation of RA.

Consumer participation in housing: reflecting on consumer preferences.

Science.gov (United States)

Browne, Graeme; Hemsley, Martin

2010-12-01

Historically, people living with mental illness have had limited chance to participate in mental health services other than as patients. Following on from a recent review focusing on consumer participation in mental health services, this paper looks at consumer participation in housing. Housing is a critical element in recovery from mental illness. Without suitable housing, people have little chance of maintaining other resources in their lives, such as supportive social relationships and meaningful activities. Consumer participation is not a common topic in the recent literature, despite the significant public policy push to promote it. The importance of appropriate housing to the recovery of people living with mental illness cannot be underestimated. Even well-meaning and well-resourced housing initiatives can fall short of meeting consumers' recovery goals when they do not incorporate the expressed needs of consumers. These expressed needs include keeping units small in size and employing drop-in support models.

NCSU solar energy and conservation house. Final report

Energy Technology Data Exchange (ETDEWEB)

1981-10-01

A passive solar energy house has been built adjacent to the NCSU McKimmon Continuing Education Center. The house contains a two-story embedded sunspace, two Trombe walls, active solar hot water heating, thermal storage in a rock filled ceiling/floor, and numerous research treatments, and energy conservation features. (See attached photo brochure; Appendix 1). The house is completely decorated and furnished in an attractive manner and the exterior architecture is traditional and has broad consumer appeal. It is also thoroughly instrumented to monitor performance. The house is open to the public on weekends and numerous people come to visit on their own initiative and others take advantage of the close proximity to McKimmon while there attending conferences. The house will influence and motivate large numbers of people to consider solar and energy conservation facets in their homes and will provide data to substantiate performance to prospective home buyers and meaningful data on design and construction for builders.

ANALYSIS OF CLIMATIC AND SOCIAL PERFORMANCES OF LOW COST TERRACE HOUSING (LCTH: INTRODUCING THE AFFORDABLE QUALITY HOUSING (AQH CONCEPT IN MALAYSIA

Directory of Open Access Journals (Sweden)

Noor Hanita Abdul Majid

2009-03-01

Full Text Available Low cost terrace housing (LCTH is the most common form and popular typology of public housing in Malaysia. The provision of the houses is deemed to be the most suitable to fulfil the needs to house low income families, and also as an alternative to high rise low cost housing. Since the implementation of these housing types, development on the layout and sizes of the house has taken place to provide for better living conditions. Literature review on the current LCTH suggested that there are deficiencies in fulfilling the requirements to provide quality and affordable housing for the low income families. This paper presents the scenario of the LCTH design based on secondary findings by researchers on housing in Malaysia. The secondary data provided the grounds for the proposal of affordable and quality housing (AQH to handle the problems that occurred at the LCTH. Both social and climatic considerations are included in the AQH, addressing issues on privacy, segregation of genders and community interaction; along with thermal comfort and natural ventilation. Decisions on the AQH are carefully extracted from a comparison analysis in the view to improve the current conditions. In order to verify some of the decisions on climatic design strategies, simulation results are presented. The results indicated that the design decisions have managed to improve on the natural ventilation conditions at the low cost houses. With reservations on the social conditions that are yet to be tested at the actual houses, the AQH has proven to be a step forward towards the provision of a better living environment.

A pilot program was developed to provide the housing industry with a means to field test innovative technologies, products and building systems, and to evaluate their overall performance. Under Canada`s Advanced House Program, ten demonstration houses were designed, built and monitored. Ottawa`s Innova House, was one of the ten houses built for this program. The innovative energy saving features of the house included (1) air distribution with small diameter ducts and an electronically commutated motor, a 2.6 kW grid-connected photovoltaic system, (3) an energy recovery ventilator (ERV) with free-cooling mode, (4) a 94 per cent efficient integrated gas heating and hot water system, (5) airtight drywall construction, (6) CFC-free exterior insulation, (7) a natural-gas-engine heat pump for air conditioning, (8) a prototype sealed combustion gas range and clothes dryer, and (9) a manifold plumbing system to conserve water. It was designed to consume one half of the energy consumed in an R-2000 home and one third of the energy of a conventional house. Several of the mechanical elements did not perform at expected levels, (lower than expected efficiencies from the heating and cooling systems and a malfunctioning ERV), nevertheless, overall performance of the house was still very close to the targets. The construction and operation of the house was described. tabs., figs.

2017-01-01

Full Text Available The paper deals with the qualitative characteristics of the housing in the EU countries. On the one hand there is a problem with housing itself and on the other hand there is a problem with the housing quality with its significant impact on the quality of life. The housing quality is defined by the attributes mentioned in the EQLS survey. The examined characters are the dwelling stock, the space problem, the rot problem, the damp problem, the toilet problem, the bath problem, the garden problem, the rent problem, the utility problem and the heating problem. The housing quality is affected by the public expenses on the housing and the community amenities per capita. The relations between the qualitative characteristics mutually and the qualitative characteristics and the public expenditures on the housing and the community amenities are examined by the correlation and regression analysis. The aim of the article is to point out to the dependence between the expenses and the housing quality in the EU countries. The mentioned relation strongly implicates the socio-economic standard of these countries.

Winther, Beate Nemeth

1997-12-31

The purpose of the study has been to investigate whether Norwegian low energy residences have a lower energy consumption throughout their existence than residences built according to the present practises. The building life span includes in this context production of the necessary building materials, construction and use of the house and demolition and handling of the demolition materials after the house lifetime is over. 5 versions of the building are analysed: 1) A residence built after the building practise according to the 1987 building regulations. 2) A residence built according to the expected practise using the 1997 regulations. 3) A low energy residence which satisfies the demands of U-Values in the 1997 technical regulations but with solar energy equipment and efficient heat recirculation of the exhaust air. 4) A well insulated, low energy residence aided by advanced solar and low energy systems that has a very low energy consumption when in operation. 5) A residence with alternative materials compared to what is normally used in Norwegian residences. The buildings are row houses built at Hamar. All the materials used are mapped. How a large part of the materials is used as well as what materials dominate the various building parts are investigated. The energy content values in most of the building materials have been determined. The yearly energy consumption for operating all the building versions is calculated and the energy for operating is 5 times higher in residences with the largest energy consumption than in residences with the lowest consumption. The energy reduction for all the technical installations used in the row house in the study is determined. The energy consumption for demolition after the life span and transporting the demolition waste is also considered. Finally an analysis is carried out for investigating how uncertainties in the various phases of the life span of the building versions may influence the obtained results. Both an

Management of Housing and Public Services of a City: the System and Simulation Approach

Directory of Open Access Journals (Sweden)

Bril Mykhailo S.

2017-12-01

Full Text Available The article is dedicated to the development of models for management of housing and communal services of a city on the basis of the system approach and simulation modeling. A review of the existing models of urban systems is carried out, their advantages and disadvantages are shown. With the use of the methods of simulation and scenario modeling, a simulation model for management of housing and communal services of a city has been developed, which makes it possible to predict the dynamics of the main socio-economic indicators of development of a city. On the basis of the model, the forecast indicators were simulated according to various scenarios for distributing financial resources for the renovation and maintenance of housing facilities of a city. The main criterion for effectiveness of the scenarios is the level of housing provision for the population. The models built can be used for making managerial decisions by local government authorities as well as in elaborating programs for the urban social and economic development.

When remediation began at the Weldon Spring Site Remedial Action Project (WSSRAP), there were 41 buildings on site. Twenty-nine of these buildings were ancillary structures and were not used for processing radioactive material. Most of these have been torn down. The remaining 12 buildings were used for uranium and thorium processing or were major support structures, such as the laboratory. Two of the buildings were major processing operations occurred were successfully demolished in February of this year. Demolition of all structures will be complete in September of this year. To give an understanding of the magnitude of the work, the following is a description of the physical characteristics of the green salt building. This building was used to convert brown oxide (UO3) to green salt (UF4), which is the last intermediate step in purifying the mostly yellow cake feed material into uranium metal.

Full Text Available Normatively a housing development in Papua is a need that can not be ignored. The relationship between economic progress with the level of economic progress is bidirectional. On one side of the housing development can stimulate economic growth and development. On the other hand economic growth particularly the growth of per capita income will increase growth in demand for home or place of residence. Theoretically the income elasticity of demand for housing is greater than one. When the economy grew 1 percent then the demand for housing will grow larger than 1 percent. In other words the demand for housing is very sensitive to economic growth. Having regard to the economic development of Papua today then greater attention and seriously to the problem of housing especially housing should have become the governments main agenda of both central and local government of Papua. The issue is whether the real problem of public housing in Papua The answer to this question is very important in order to avoid overlapping of activities and housing policy will only be a waste of resources in Papua

1985-01-01

Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, alt...

Climate-neutral buildings are possible

International Nuclear Information System (INIS)

Berge, Bjoern

2002-01-01

Buildings account for considerable climatic loads throughout their construction, use and demolition. This is because of the emission of carbon dioxide and other greenhouse gases from the production and transport of materials, the energy consumption of the house and, finally, the treatment of the waste material from the demolition. Furthermore, there are issues related to carbon binding, re-cycling and heat value. The author asserts that, if these issues are considered during the design phase, the total climate load of the building can be reduced and sometimes even eliminated

The characteristics of households, of housing and their relation influence the housing situation in the city. Characteristic of housing refer mainly to quality of the dwellings, affordability and correspondence to the wishes of the inhabitants. The second important dimensions are households and their characteristics. In Europe and Slovenia increase in number of household can be observed, which in turn are becoming smaller. The housing policy has a role in establishing a balance between households and housing, i.e. ensuring that housing corresponds to the needs of individual households and to their number. For achieving this, knowledge and appropriate data are of vital importance. In the article we present the results of the Housing survey 2005. We observe housing conditions in a comparative perspective (Ljubljana in comparison to Maribor, Slovenia and selected European cities and according to three dimensions: housing fund, households and housing conditions.

Many behaviours not tolerated in the community (e.g. public masturbation) are acceptable in the home but there are limits and rules (e.g. not in the dining room). A good home needs the responsible person to be open, honest, understanding and sensitive to changes in guests. Psychiatric services and welfare agencies need to recognise the major contributions of well-run boarding houses and need to liaise more with the proprietors.

Four different types of fuel blends containing demolition and construction wood and household waste were combusted in a small-scale experimental set-up to study the effect of fuel composition on the emissions of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), biphenyls (PCBs), chlorobenzenes (PCBzs), chlorophenols (PCPhs) and polycyclic aromatic hydrocarbons (PAHs). Two woody materials, commercial stemwood (ST) and demolition and construction wood (DC) were selected because of the differences in their persistent organic pollutants (POPs), ash and metals content. For household waste, we used a municipal solid waste (MSW) and a refuse-derived fuel (RDF) from MSW with 5-20 wt% and up to 5 wt% food waste content respectively. No clear effect on the formation of pollutants was observed with different food waste content in the fuel blends tested. Combustion of ST-based fuels was very inefficient which led to high PAH emissions (32 ± 3.8 mg/kg fuel ). The use of DC clearly increased the total PCDD and PCDF emissions (71 ± 26 μg/kg fuel ) and had a clear effect on the formation of toxic congeners (210 ± 87 ng WHO 2005 -TEQ/kg fuel ). The high PCDD and PCDF emissions from DC-based fuels can be attributed to the presence of material contaminants such as small pieces of metals or plastics as well as timber treated with chromated copper arsenate preservatives and pentachlorophenol in the DC source.

Emerging evidence about the effects of endocrine disruptors on asthma symptoms suggests new opportunities to reduce asthma by changing personal environments. Right-to-know ethics supports returning personal results for these chemicals to participants, so they can make decisions to reduce exposures. Yet researchers and institutional review boards have been reluctant to approve results reports in low-income communities, which are disproportionately affected by asthma. Concerns include limited literacy, lack of resources to reduce exposures, co-occurring stressors, and lack of models for effective reporting. To better understand the ethical and public health implications of returning personal results in low-income communities, we investigated parents' experiences of learning their children's environmental chemical and biomonitoring results in the Green Housing Study of asthma. The Green Housing Study measured indoor chemical exposures, allergens, and children's asthma symptoms in "green"-renovated public housing and control sites in metro-Boston and Cincinnati in 2011-2013. We developed reports for parents of children in the study, including results for their child and community. We observed community meetings where results were reported, and metro-Boston residents participated in semi-structured interviews in 2015 about their report-back experience. Interviews were systematically coded and analyzed. Report-back was positively received, contributed to greater understanding, built trust between researchers and participants, and facilitated action to improve health. Sampling visits and community meetings also contributed to creating a positive study experience for participants. Participants were able to make changes in their homes, such as altering product use and habits that may reduce asthma symptoms, though some faced roadblocks from family members. Participants also gained access to medical resources, though some felt that clinicians were not responsive

Housing instability can complicate parents' efforts to provide for their children. Child welfare service agencies have had difficulty adequately serving parents' housing needs due to limited and constrained funding streams. This article integrates the voices of four important stakeholders to illuminate how an innovative model of service system coordination called Linkages addresses housing needs for child welfare-involved parents eligible for public assistance. Facilitated by Linkages, these parents can receive supportive housing services through programs affiliated with the California public assistance program CalWORKs. Personal narratives reflecting the diverse perspectives of stakeholders in the Linkages collaboration-the statewide program director, a child welfare services coordinator, a CalWORKs caseworker, and a parent program participant-shed light on how the collaboration assists parents in attaining case plan goals, and highlights some of the factors facilitating and hindering effective collaboration between the agencies involved. Stakeholders emphasized the value of flexible service approaches, the intensity of the efforts required, the role of advocacy, and the importance of a shared vision between agencies working together to provide housing supports. © Society for Community Research and Action 2016.

Civil rights as determinants of public health and racial and ethnic health equity: Health care, education, employment, and housing in the United States.

This essay examines how civil rights and their implementation have affected and continue to affect the health of racial and ethnic minority populations in the United States. Civil rights are characterized as social determinants of health. A brief review of US history indicates that, particularly for Blacks, Hispanics, and American Indians, the longstanding lack of civil rights is linked with persistent health inequities. Civil rights history since 1950 is explored in four domains-health care, education, employment, and housing. The first three domains show substantial benefits when civil rights are enforced. Discrimination and segregation in housing persist because anti-discrimination civil rights laws have not been well enforced. Enforcement is an essential component for the success of civil rights law. Civil rights and their enforcement may be considered a powerful arena for public health theorizing, research, policy, and action.

This study presents a Quality of Life (QoL) survey to understand the influence of the housing environment and needs of residents from different housing sectors. The research focuses on Hong Kong where living conditions have become the main affect for people's QoL. Through a household survey using a standard instrument "Word Health Organisation (WHO) Quality of Life-BREF", the article found that among the four WHO QoL domains (Physical Health, Psychological Health, Social Relations And Environment), Environment, particularly its constitute aspect housing environment was the most influential factor for overall quality of life for the public rental housing sector where low-income people live. This research also found that different groups of people have differing needs of their housing environments: the low-income group needs better location and privacy while the medium and high-income groups need better architectural quality. Based on differentiating their needs and wants, this research argues for prioritizing the low-income group's needs for effectively improving their QoL.
