Building Energy-Efficient Schools in New Orleans: Lessons Learned (Brochure)

Energy Technology Data Exchange (ETDEWEB)

2011-12-01

This case study presents the lessons learned from incorporating energy efficiency in the rebuilding and renovating of New Orleans K-12 schools after Hurricanes Katrina and Rita. Hurricane Katrina was the largest natural disaster in the United States, striking the Gulf Coast on August 29, 2005, and flooding 80% of New Orleans; to make matters worse, the city was flooded again only three weeks later by the effects of Hurricane Rita. Many of the buildings, including schools, were heavily damaged. The devastation of schools in New Orleans from the hurricanes was exacerbated by many years of deferred school maintenance. This case study presents the lessons learned from incorporating energy efficiency in the rebuilding and renovating of New Orleans K-12 schools after Hurricanes Katrina and Rita. The experiences of four new schools-Langston Hughes Elementary School, Andrew H. Wilson Elementary School (which was 50% new construction and 50% major renovation), L.B. Landry High School, and Lake Area High School-and one major renovation, Joseph A. Craig Elementary School-are described to help other school districts and design teams with their in-progress and future school building projects in hot-humid climates. Before Hurricane Katrina, New Orleans had 128 public schools. As part of the recovery planning, New Orleans Public Schools underwent an assessment and planning process to determine how many schools were needed and in what locations. Following a series of public town hall meetings and a district-wide comprehensive facility assessment, a Master Plan was developed, which outlined the renovation or construction of 85 schools throughout the city, which are expected to be completed by 2017. New Orleans Public Schools expects to build or renovate approximately eight schools each year over a 10-year period to achieve 21st century schools district-wide. Reconstruction costs are estimated at nearly $2 billion.

The Thacher School is in the process of renovating the campus observatory with a new meter class telescope and full automation capabilities for the purpose of scientific research and education. New equipment on site has provided a preliminary site characterization including seeing and V-band sky brightness measurements. These data, along with commissioning data from the MINERVA project (which uses comparable hardware) are used to estimate the capabilities of the observatory once renovation is complete. Our V-band limiting magnitude is expected to be better than 21.3 for a one minute integration time, and we estimate that milli-magnitude precision photometry will be possible for a V=14.5 point source over approximately 5 min timescales. The quick response, autonomous operation, and multi-band photometric capabilities of the renovated observatory will make it a powerful follow-up science facility for exoplanets, eclipsing binaries, near-Earth objects, stellar variability, and supernovae.

Kinds of initial billets in renovation technologies

Directory of Open Access Journals (Sweden)

V. M. Yaroslavtsev

2014-01-01

Full Text Available Nowadays, technologists in charge of repair, restoration, modernization, and utilization of engineering and other tangible objects widely use the concepts "renovation" and "renovation technologies" pioneered at BMSTU. In forming a new field of science these concepts, in the proper sense of the word, are of composite, generalized character. They concern all the activities and technologies aimed at increasing an object resource or its lifecycle extension, including object material recycling.In the cutting-edge renovation technologies an object (part, assembly, machine, etc. damaged in the operating process is considered to be an initial billet. In renovation, one of the most widespread kinds of initial billets is a damaged part.Such a part can be used again, if, for example, it has saved its material properties in full measure while only contact surfaces or parts of these surfaces have become damaged, and at a point of renovation they can be restored for recycling. If a part has lost its initial properties in full bulk of material, it may be reusable in the assemblies and machines with less rigid requirements for material properties.Or in case of properties loss below the permissible level a damaged part-billet is utilized. Thus, the part-billet state at the point of renovation defines the kind of renovation technology and the main (basic technological method to effect on the damaged part, as well as a set and a sequence of technological methods in general manufacturing process of renovation.However renovation technologies are used not only at the repair and restoration stages after operation-service. So, at the manufacturing stage of a new product to provide the quality to raise a resource are applied the same technological methods as renovation technologies for the objects damaged at the stage of operation. Besides, it is known that at the manufacturing stage a part quality depends not only on the last operation, but also on the features of

This paper presents a maximization model determining the optimal time at which a mall should be renovated. The analysis is constructed on the assumption of a decreasing rental income over time as a mall ages. It is then shown that the optimal renovation period achieves a balance between the marginal cost and benefits of delaying renovation. We show how this balance is affected by changes in the discount rate, net rental incomes, and renovation costs. Numerical simulations are used to demonstr...

product where the initial condition of material to produce the same-named details differs within the narrow standards-set limits.Technological process of renovation has to ensure restoration of all properties necessary to provide the subsequent operation and demanded work resource of the technical object turned to be an initial preform. The object, which is off-specifications and off-technical regulatory documents, in this case is a carrier of the hereditary information of life cycle, that it have saved up by the time of renovation. This information represents basic data to make decisions on possibility and efficiency of carrying out renovation works, defining their amounts, selecting technological methods of processing, their rational sequence, and means of technological support of the product quality.In this regard technological support of quality and work-related properties of the renovated objects directly depends on the knowledge of those properties of initial preform which will be imparted from one technological operation to the other at all stages of the route technology. Thus it is important to take into consideration that a product processed by each previous method with a complex of its output characteristics and properties is the preform for the subsequent method and itself conveys effect of the life cycle heredity of a product by the time under consideration. For example, the available results of pilot studies show that the strain structural anisotropy of material occurring after processing by pressure, rolling in particular, results in strain anisotropy of cutting process.Thus strain anisotropy of the main component of the cutting force Pz , can be of ~ 8-10%. Thus, high heterogeneity of properties of renovated objects with the same name, purpose, and application demands an individual approach to each of them, i.e. the corresponding correction of operation conditions, fast readjustment of technological system, and change of other processing conditions.

Energy savings from housing: Ineffective renovation subsidies vs efficient demolition and reconstruction incentives

International Nuclear Information System (INIS)

Dubois, Maarten; Allacker, Karen

2015-01-01

Energy savings in the housing sector are key to reduce global greenhouse gas emissions. Policies to incentivize energy savings are however disparate between countries. Taking into account environmental aspects and consumer surplus, the paper uses a stylized economic model to assess the effectiveness and efficiency of three economic instruments: subsidies for renovation, subsidies for demolition and reconstruction projects and subsidies for building new houses on virgin land. The assessment also relates to differentiated value added taxes and other financial incentives such as green loans. In a counter-intuitive way, the model highlights that subsidies for renovations with minor energy gains worsen the overall energy consumption of housing due to the inducement of lock-ins with energy inefficient houses. Structural changes are needed in the use of policy instruments. First, commonly applied support schemes for renovations with minor energy savings should be abolished. Second, scarce public resources should incentivize deep renovation and demolition and reconstruction. Finally, taxes should apply on the use of virgin land to persuade households with a high willingness to pay for a new house, to invest in demolition and reconstruction. - Highlights: • Renovation subsidies worsen overall energy consumption of housing. • Renovation induces a lock-in with energy inefficient houses. • Renovation subsidies should be abolished or structurally reformed. • Policy should incentivize demolition and reconstruction projects. • Building on virgin land should be taxed.

Actual heating energy savings in thermally renovated Dutch dwellings

Majcen, Daša; Itard, Laure; Visscher, Henk

2016-01-01

The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

Housing industry in Malaysia is growing rapidly due to the increase in population and the arising of economic level of Malaysian people. Most residential houses are built according to the standard residential design that may lead to house renovation by the buyers after purchasing the house. A method of using Unmanned Aerial Vehicle (UAV) monitoring was used to obtain information of the renovated houses directly on-site at Taman Manis 2, Parit Raja, Batu Pahat. Through comparison of image captured by the UAV with the original house plans, we found out that a total of 160 units out of 336 units of houses undergo a renovation process. Surprisingly, 41 units have been renovated illegally which has 40% to 96% of renovation rate. The acquired data were analyzed and can be concluded that the method of using UAVs to obtain information is highly recommended. The study is expected to help Municipal Council to detect improper & illegal renovation by the residents in a residential area.

Proper pasture management is important in promoting optimal forage growth and reducing runoff and nutrient loss. Pasture renovation is a management tool that improves aeration by mechanically creating holes or pockets within the soil. Pasture renovation was performed before manure application (poultry litter or swine slurry) on different pasture soils and rainfall simulations were conducted to identify the effects of pasture renovation on nutrient runoff and forage growth. Renovation of small plots resulted in significant and beneficial hydrological changes. During the first rainfall simulation, runoff volumes were 45 to 74% lower for seven out of eight renovated treatments, and infiltration rates increased by 3 to 87% for all renovated treatments as compared with nonrenovated treatments. Renovation of pasture soils fertilized with poultry litter led to significant reductions in dissolved reactive P (DRP) (74-87%), total P (TP) (76-85%), and total nitrogen (TN) (72-80%) loads in two of the three soils studied during the first rainfall simulation. Renovation did not result in any significant differences in forage yields. Overall, beneficial impacts of renovation lasted up to 3 mo, the most critical period for nutrient runoff following manure application. Therefore, renovation could be an important best management practice in these areas.

Renovation and uprating of seven hydropower plants in Java

International Nuclear Information System (INIS)

Nuessli, W.

1991-01-01

The Indonesian Power Authority is planning to renovate and uprate seven hydropower stations in Java to expand plant life expectancy, ensure operating safety and reliability, and increase power and generation within economical limits. The power plants were constructed in the early 1920s and extended between 1945 and 1950. Their capacities vary between 4 and 20 MW. For the renovation project, Colenco Power Consulting Ltd. is acting as a consultant to PLN. In February 1990, Colenco inspected all seven power plants. The results of the inspections served as the basis for the development of renovation plans for each of the seven hydropower plants. To determine the cost of the proposed renovation plans, appraisers had to determine a method for comparing the value of an existing plant to that of a renovated one. The two different evaluation methods used for these comparisons are the focus of this paper

The building stock from perspective of change - renovation roadmap

Energy Technology Data Exchange (ETDEWEB)

Airaksinen, M., Email: miimu.airaksinen@vtt.fi

2012-06-15

By 2050, population, society and economic structures will have changed several times. The long and short-term goals and objectives concerning our built environment are mutually contradictory. Determining objectives or creating scenarios for the future built environment is fruitless. We should approach the development of the built environment from the perspective of change and improve the flexibility and adaptability of the built environment. For the users, a built environment meeting their basic needs is part of sustainable development. Identified short-range renovation needs include eliminating damp and mould problems, improving energy and eco-efficiency, removing obstacles to mobility and adapting buildings to accommodate the needs of the elderly. Vacated areas and buildings should be recycled and offered a new life supporting a sense of community and service production. Improved energy efficiency reduces greenhouse gas emissions. Instead of renovating individual buildings, renovation of the entire area is recommended. Sustainability in construction translates into favouring recycling and renewable materials and building-specific energy systems using renewable and/or low-emission resources. It is recommended that renovations to improve energy efficiency are scheduled to coincide with other maintenance/ renovations so as to reduce costs. In renovation construction, the role of service improvement is more important than products. Improved services help to identify a solution that fulfils several customer needs, meets financial limitations and can be implemented efficiently. Companies are advised to view renovation construction as an innovative market segment entitled to its own service portfolio. Truths about new building should be discarded and new services developed based on recent study results and new technologies. (orig.)

Renovation of the Stockholm sewerage system

International Nuclear Information System (INIS)

Sandin, Paer

1987-01-01

Within a few years Stockholm will let all its treated wastewater into the Saltsjoen. The Saltsjoen is the inner part of the Stockholm Archipelago, which is one of the finest recreation areas in Sweden and where many Stockholmians spend a great deal of their leisure time. That is one reason why it is so important that all wastewater is treated before it reaches the recipient. A sewerage system in bad condition means that the risk of not allowed/unplanned overflows is increased. In order to prevent overflows we drafted 'Plan 83' which tells us how our sewerage system shall be constructed in the future and what measures has to be made in the system. Renovations of the existing pipes is one method to get a well functioning sewer system. Today we have made about 50 different objects at a total length of 6000 m. Why do we renovate sewers and why are we attempting to develop methods for pipe renovations?

Sánka, Imrich; Földváry, Veronika

2017-06-01

This study investigates the impact of energy renovation on the indoor air quality of an apartment building during the heating season. The study was performed in one residential building before and after its renovation. An evaluation of the indoor air quality was performed using objective measurements and a subjective survey. The concentration of CO2 was measured in the bedrooms, and a sampling of the total volatile compounds (TVOC) was performed in the living rooms of the selected apartments. Higher concentrations of CO2 and TVOC were observed in the residential building after its renovation. The concentrations of CO2, and TVOC in some of the cases exceeded the recommended maximum limits, especially after implementing energy-saving measures on the building. The average air exchange rate was visibly higher before the renovation of the building. The current study indicates that large-scale renovations may reduce the quality of an indoor environment in many apartments, especially in the winter season.

The Strategic-Renovation Banks’ Risks Management

Directory of Open Access Journals (Sweden)

Yeremeychuk Raisa A.

2017-04-01

Full Text Available The article is aimed at developing approaches to implementation of the strategic-renovation risk management. Essence of risk theories was researched, the concept of «risk» in the bank’s management system were analyzed. On the basis of a theoretical generalization of scientific literature and the carried out analysis of existing risk management strategies to ensure the security of banking business, the strategy of renovation management has been selected. Because bank risks are part of the economic risk system, they are complex in their nature. However, given the importance of bank risks, the interpretation of their essence is still a debating matter. In a certain number of cases, their essence is replaced by the cause of occurrence, that is, all the different circumstances, factors that lead to the losses. So today, banks are considering risks, in particular, not only as a source of possible losses, but also as an opportunity to generate additional profits. An algorithm for taking a strategic-renovation decision on the banks’ risks management system has been proposed.

Method for a component-based economic optimisation in design of whole building renovation versus demolishing and rebuilding

International Nuclear Information System (INIS)

Morelli, Martin; Harrestrup, Maria; Svendsen, Svend

2014-01-01

Aim: This paper presents a two-fold evaluation method determining whether to renovate an existing building or to demolish it and thereafter erect a new building. Scope: The method determines a combination of energy saving measures that have been optimised in regards to the future cost for energy. Subsequently, the method evaluates the cost of undertaking the retrofit measures as compared to the cost of demolishing the existing building and thereafter erecting a new one. Several economically beneficial combinations of energy saving measures can be determined. All of them are a trade-off between investing in retrofit measures and buying renewable energy. The overall cost of the renovation considers the market value of the property, the investment in the renovation, the operational and maintenance costs. A multi-family building is used as an example to clearly illustrate the application of the method from macroeconomic and private financial perspectives. Conclusion: The example shows that the investment cost and future market value of the building are the dominant factors in deciding whether to renovate an existing building or to demolish it and thereafter erect a new building. Additionally, it is concluded in the example that multi-family buildings erected in the period 1850–1930 should be renovated. - highlights: • Development of a method for evaluation of renovation projects. • Determination of an economic optimal combination of various energy saving measures. • The method compared the renovation cost to those for demolishing and building new. • Decision was highly influence by the investment cost and buildings market value. • The results indicate that buildings should be renovated and not demolished

Evaluation of airborne particulates and fungi during hospital renovation.

Science.gov (United States)

Overberger, P A; Wadowsky, R M; Schaper, M M

1995-07-01

This study was conducted over 30 weeks on a hospital floor undergoing partial renovation. Some patients housed on the floor were immunosuppressed, including bone marrow transplant recipients. The construction zone was placed under negative pressure and was separated from patient rooms by existing hospital walls and via erection of a temporary barrier. Other control measures minimized patient exposure to airborne materials. Air sampling was done for 3 weeks prior to construction, 24 weeks during construction, and 3 weeks after renovation was completed. Airborne particulate concentrations, total spore counts, particle size, and fungal species were assessed. At the beginning of the renovation there were increases in airborne particulates (from 0.2 to 2.0 mg/m3) and fungal spores (from 3.5 to 350 colony forming units (CFU/m3), but only in the construction zone. Throughout the remainder of the renovation, particulate and fungal spore levels fluctuated inside the construction zone but remained close to baseline values in the patient area. When renovation was completed, particulates and spore counts inside the construction zone decreased to preconstruction levels. The primary fungus isolated from air samples was Penicillium. This study demonstrated that control measures were effective in reducing exposures of hospitalized patients to airborne particulates and spores and in reducing the increased risk of aspergillosis and other fungal infections associated with hospital construction projects. The data from this study may be useful in establishing exposure guidelines for other health care settings.

Cost-optimal energy performance renovation measures of educational buildings in cold climate

International Nuclear Information System (INIS)

Niemelä, Tuomo; Kosonen, Risto; Jokisalo, Juha

2016-01-01

Highlights: • The proposed national nZEB target can be cost-effectively achieved in renovations. • Energy saving potential of HVAC systems is significant compared to the building envelope. • Modern renewable energy production technologies are cost-efficient and recommendable. • Improving the indoor climate conditions in deep renovations is recommendable. • Simulation-based optimization method is efficient in building performance analyzes. - Abstract: The paper discusses cost-efficient energy performance renovation measures for typical educational buildings built in the 1960s and 1970s in cold climate regions. The study analyzes the impact of different energy renovation measures on the energy efficiency and economic viability in a Finnish case study educational building located in Lappeenranta University of Technology (LUT) campus area. The main objective of the study was to determine the cost-optimal energy performance renovation measures to meet the proposed national nearly zero-energy building (nZEB) requirements, which are defined according to the primary energy consumption of buildings. The main research method of the study was simulation-based optimization (SBO) analysis, which was used to determine the cost-optimal renovation solutions. The results of the study indicate that the minimum national energy performance requirement of new educational buildings (E_p_r_i_m_a_r_y ⩽ 170 kWh/(m"2,a)) can be cost-effectively achieved in deep renovations of educational buildings. In addition, the proposed national nZEB-targets are also well achievable, while improving the indoor climate (thermal comfort and indoor air quality) conditions significantly at the same time. Cost-effective solutions included renovation of the original ventilation system, a ground source heat pump system with relatively small dimensioning power output, new energy efficient windows and a relatively large area of PV-panels for solar-based electricity production.

Liu, Yucheng

2017-11-01

In this work, an industry-based and team-oriented education model was established based on a traditional mechanical engineering (ME) senior design class in order to better prepare future engineers and leaders so as to meet the increasing demand for high-quality engineering graduates. In the renovated curriculum, industry-sponsored projects became the most important course component and critical assessment tool, from which problem-solving skills as well as employability skills of the ME students can be fully developed. Hands-on experiences in finite element analysis (FEA) modelling and simulation were also added into the renovated curriculum to promote the application of FEA on engineering design and assessment. Evaluation of the renovated course was conducted using two instruments and the results have shown that the course made the ME senior students more prepared for their future career and a win-win model was created between the industry partner and the ME programme through it. Impact of the renovated syllabus on Accreditation Board for Engineering Technology goals was discussed. Based on the current progress, a more substantial change is being planned to further improve the effectiveness and practicability of this design course. The renovated course was started to offer to the ME senior students at Mississippi State University.

Cartwright, Jim; Contratto, Jim; Gould, Nathan; Freeman, William

2013-10-01

In the aftermath of Superstorm Sandy, new attention has been drawn to planning for and mitigating the effects of disasters on laboratory animal facilities. A number of design approaches and solutions can be easily incorporated into a new vivarium, enhancing its ability to withstand and recover from a disaster. Renovating a vivarium poses special challenges, however. Existing conditions in the project area may dictate which approaches or solutions are feasible, and retrofitting is often more complex and expensive than incorporating the same features into new construction. The authors explain how project design teams can evaluate the types of disasters that a renovated facility will need to address and develop a design strategy that responds to these disasters in the most effective way.

The contribution of housing renovation to children’s blood lead levels: a cohort study

Science.gov (United States)

2013-01-01

Background Routine renovation of older housing is a risk factor for childhood lead poisoning, but the contribution to children’s blood lead levels is poorly defined for children with lower exposure levels. Methods We examined a prospective cohort of 276 children followed from 6 to 24 months of age. We conducted surveys of renovation activities and residential lead hazards and obtained blood lead level (B-Pb) every six months. We analyzed B-Pb in a repeated measures design using a mixed effects linear model. Results Parent reported interior renovation ranged from 11 to 25% of housing units at the four, 6-month periods. In multivariable analysis, children whose housing underwent interior renovation had a 12% higher mean B-Pb by two years of age compared with children whose housing units were not renovated (p children in non-renovated housing, children whose housing units underwent renovation in the prior month had a 17% higher mean B-Pb at two years of age, whereas children whose housing renovation occurred in the prior 2–6 months had an 8% higher mean B-Pb. We also found an association between higher paint lead loading, measured using an X-ray fluorescence (XRF) based paint lead index, and child B-Pb (p = 0.02); for every 10 mg/cm2 increase in paint lead loading index there was a 7.5% higher mean childhood B-Pb. Conclusions In an analysis of data collected before the recent changes to Environmental Protection Agency’s Lead, Renovation, Repair and Painting Rule, routine interior housing renovation was associated with a modest increase in children’s B-Pb. These results are important for the provision of clinical advice, for housing and public health professionals, and for policymakers. PMID:23981571

Full Text Available Optimised project delivery methods forsocial housing energy renovations European Social Housing Organisations (SHOs are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer the possibility of upgrading the health and comfort levels of their old housing stock to current standards and improve energy efficiency, and this solution also addresses the fuel poverty problems suffered by some tenants. Unfortunately, the limited financial capacity of SHOs is hampering the scale of housing renovation projects and the energy savings achieved.  At the same time, the renovation of the existing housing stock is seen as one of the most promising alternative routes to achieving the ambitious CO2 emissions reduction targets set by European authorities – namely, to reduce EU CO2 emissions to 20% below their 1990 levels by 2020. The synergy between European targets and the aims of SHOs has been addressed by the energy policies of the member states, which focus on the potential energy savings achievable by renovating social housing. In fact, the European initiatives have prioritised energy savings in social housing renovations to such an extent that these are referred to as ‘energy renovations’. Energy renovation is therefore a renovation project with higher energy savings target than a regular renovation project. In total, European SHOs own 21.5 million dwellings representing around 9.4% of the total housing stock. Each SHO owns a large number of dwellings, which means there are fewer people to convince of the need to make energy savings through building renovations, maximising the potentially high impact of decisions. Moreover, SHOs are responsible for maintaining and upgrading their properties in order to continue

Energy consumption of buildings accounts for around 20-40% of all energy consumed in advanced countries. Over the last decade, more and more global organizations are investing significant resources to create sustainably built environments, emphasizing sustainable building renovation processes to reduce energy consumption and carbon dioxide emissions. This study develops an integrated decision support system to assess existing office building conditions and to recommend an optimal set of sustainable renovation actions, considering trade-offs between renovation cost, improved building quality, and environmental impacts. A hybrid approach that combines A* graph search algorithm with genetic algorithms (GA) is used to analyze all possible renovation actions and their trade-offs to develop the optimal solution. A two-stage system validation is performed to demonstrate the practical application of the hybrid approach: zero-one goal programming (ZOGP) and genetic algorithms are adopted to validate the effectiveness of the algorithm. A real-world renovation project is introduced to validate differences in energy performance projected for the renovation solution suggested by the system. The results reveal that the proposed hybrid system is more computationally effective than either ZOGP or GA alone. The system's suggested renovation actions would provide substantial energy performance improvements to the real project if implemented. (author)

Arumägi, Endrik; Kalamees, Targo

2014-01-01

Highlights: • Energy saving potential in historic wooden apartment buildings is up to 63%. • In historic wooden apartment buildings an economically viable energy saving level is 50%. • The largest energy saving potential lies in heat source and building service systems. • Of the building structures, insulation of the external wall has the highest potential. • New heating and ventilation systems must be installed to fulfill regulations limits. - Abstract: Buildings represent the largest sector of primary energy consumption and play a major role in saving energy and reducing greenhouse gas emissions. Our analysis of energy consumption and potential energy savings is based on field measurements, computer simulations and economic calculations. The average primary energy consumption (PE) of wooden apartment buildings was 331 kW h/(m 2 a) 83% higher than the limit 180 kW h/(m 2 a) set in national regulations for apartment buildings subject to major renovation. The studied buildings represent a high potential for energy savings. The renovation packages were compiled using different insulation measures, HVAC solutions and energy sources to achieve a 20–65% reduction of primary energy. For historic buildings, the renovation solutions that concentrate on the building envelope can be problematic due to the need to preserve cultural and architectural values. Our calculation results indicate that the cost optimal PE level is around 250 kW h/(m 2 a) and the point at which renovation packages recover expenses is around a PE level of 170 kW h/(m 2 a). In terms of the architectural appearance the point at which renovation packages recover expenses is around a PE level of 210 kW h/(m 2 a). We propose to set a different PE limit for historic wooden apartment buildings with an architectural appearance worth preserving

Highlights: ► In the Nordic countries there is significant primary energy saving potential in single-family houses from 1970s. ► There are several behavioral, economical and market related hindrances to adoption of energy efficiency measures. ► One-stop-shop business models to offer full service energy renovation packages are slowly emerging. ► Marketing strategies and policy measures are required to promote full service energy renovation of single-family house. - Abstract: In Nordic countries significant primary energy saving potential exists in houses built before 1980. These old houses need to be renovated, which provides an opportunity for implementation of energy efficiency measures. However, there are several economic and market hindrances and the renovation markets are dominated by handicraft-based individual solutions. In this paper we have analyzed the opportunities for implementation of one-stop-shop business models where an overall contractor offers full-service renovation packages including consulting, independent energy audit, renovation work, follow-up (independent quality control and commissioning) and financing. A comparative assessment of emerging business models in the Nordic countries shows that different types of actors can provide such a service. Financing is included in some models. There are differences in how customers are contacted, while the similarities are on how the service is provided. Even though there is strong business potential for one-stop-shop energy renovation concept, still it has been somewhat difficult to start or run such a business. Various options to overcome the hindrances to promote energy efficient renovation of detached houses are discussed

On the Testing of Renovations Inside Historical Opera Houses

Science.gov (United States)

Fausti, P.; Prodi, N.

2002-11-01

Due to the large number of historical opera houses in Italy, many theatres have been renovated in the past, but still more will undergo major restoration in the near future. Unfortunately in this context, the quality and protection of acoustics is rarely considered as an issue of its own. As a consequence, the renovations are hardly ever accompanied by proper scientific and technical support. In this paper, the acoustical impact of works inside the Teatro Municipale "R.Valli" in Reggio Emilia, including the restoration of the main hall and the construction of a new acoustic shell, will be dealt with. Surveys were held in the theatre before renovation and were repeated with identical procedure and instruments after its completion. By means of a comparative analysis of the architectural project and of acoustical data, the impact of major changes in the theatre can be predicted. It is shown that this approach can help in drafting an operational scheme for safeguarding the acoustics of historical opera houses.

What factors increase the chance that residents/owners in housing cooperatives agree on sustainable energy efficient renovation? Based on 30 qualitative interviews with professional advisors in cooperative housing associations and chairman/board and residents in three chosen case studies, an analysis of opportunities and barriers for making a common decision on renovation is performed. Success criteria and barriers are found on the societal level as well as on the organizational/individual level. The barriers and success criteria identified on the societal level are: knowledge level on energy-efficient renovation among relevant actors, owner structure of the housing cooperative, and existing regulations and incentives. On the organizational and individual level, the following categories influencing renovation processes were identified: the time frame and organization of the process, understanding the residents' needs, economy, the information given, and the existence of available exemplary projects and role models. Based on the results of the study, ten guidelines that contribute to more successful decision making processes and increase the chances of sustainable energy efficient renovation in housing cooperatives are presented.

Full Text Available Exposure to volatile organic compounds (VOCs has been an indoor environmental quality (IEQ concern in schools and other buildings for many years. Newer designs, construction practices and building materials for “green” buildings and the use of “environmentally friendly” products have the promise of lowering chemical exposure. This study examines VOCs and IEQ parameters in 144 classrooms in 37 conventional and high performance elementary schools in the U.S. with the objectives of providing a comprehensive analysis and updating the literature. Tested schools were built or renovated in the past 15 years, and included comparable numbers of conventional, Energy Star, and Leadership in Energy and Environmental Design (LEED-certified buildings. Indoor and outdoor VOC samples were collected and analyzed by thermal desorption, gas chromatography and mass spectroscopy for 94 compounds. Aromatics, alkanes and terpenes were the major compound groups detected. Most VOCs had mean concentrations below 5 µg/m3, and most indoor/outdoor concentration ratios ranged from one to 10. For 16 VOCs, the within-school variance of concentrations exceeded that between schools and, overall, no major differences in VOC concentrations were found between conventional and high performance buildings. While VOC concentrations have declined from levels measured in earlier decades, opportunities remain to improve indoor air quality (IAQ by limiting emissions from building-related sources and by increasing ventilation rates.

Captive African (Loxodonta africana) and Asian (Elephas maximus) elephants can experience foot pathologies and arthritis. As a preventative measure against these pathologies and to alleviate the potential discomfort due to concrete substrates, some zoological institutions have renovated elephant housing to increase the amount of natural or shock-absorbent substrates. The objective of this study was to compare behavioral (diurnal and nocturnal) and glucorticoid (e.g., serum cortisol) responses of three female African elephants before, during, and after renovation to their indoor housing floor to assess whether renovations had short-term effects on the elephants’ behavior and stress physiology. Behavioral data were collected using scan-sampling methods, and activity budgets were constructed for each of the three elephants. In addition, the duration of all lying rest activities were recorded. Weekly serum cortisol concentrations were determined with enzyme immunoassay (EIA). Overall, eating was the most prevalent behavior exhibited outdoors during the day, while resting (either in a lying or standing position) were most common during the indoor, nocturnal periods. Although variation existed among the three elephants, all three females spent significantly more time walking and less time eating during the day after the completion of the renovations. The extent to which the three elephants exhibited nocturnal lying rest behavior varied among the elephants, with the oldest elephant exhibiting the least amount (an average of 13.2 ± 2.8% of the nightly behavioral scans) compared to the two younger elephants (an average of 34.5 ± 2.1% and 56.6 ± 2.8% of the nightly behavioral scans). There was a significant increase in lying rest behavior for one elephant and standing rest for a second elephant following renovations. Baseline cortisol concentrations prior to renovations were 3.0 ± 0.4 ng/ml, 4.5 ± 0.5 ng/ml, and 4.9 ± 0.5 ng/ml for the three elephants. Cortisol

Building renovations in BIM systems

Directory of Open Access Journals (Sweden)

Smutný Marian

2018-01-01

Full Text Available Renovation of buildings is a demanding challenge for computer systems. Nowadays, complex 3D models of historic buildings can be scanned and modelled, including sculptural filigrees and stucco decorations with possibility to generate different projections, cross-sections and elevations according to descriptive geometry rules. However, all of this falls within the field of “3D Modelling”. BIM systems work with elements that have to be classified according to their purpose, or according to the way they are realized. The system is then able to sort, filter or group them. Also, it is able to compute their bill of quantity and quality based on their attributes. Last but not least, it has to be able to schematically display civil engineering drawings on the basis of classification of the elements which differ considerably from the display of descriptive geometry. In regular constructions, repeatability and predictability of the links between the elements suit computer systems. Thus, the issue of building renovations in BIM systems is to find a balance between modelling irregular constructions and irregular space arrangements, while maintaining the ability to interact with other BIM elements.

Renovation of the control system of the CERN LHC injectors was initiated in 2007 in the scope of the Injector Controls Architecture (InCA) project. One of its main objectives was to homogenize the controls software across CERN accelerators and reuse as much as possible the existing modern sub-systems, such as the settings management used for the LHC. The project team created a platform that would permit coexistence and intercommunication between old and new components via a dedicated gateway, allowing a progressive replacement of the former. Dealing with a heterogeneous environment, with many diverse and interconnected modules, implemented using different technologies and programming languages, the team had to introduce all the modifications in the smoothest possible way, without causing machine downtime. After a brief description of the system architecture, the paper discusses the technical and non-technical sides of the renovation process such as validation and deployment methodology, operational applicatio...

Measuring quality of care is essential to improve primary care. Quality of primary care for patients is usually assessed by patient satisfaction questionnaires. However, patients may not be able to judge quality of care without also reflecting their perception of the environment. We determined the effect that redesigning a primary care office had on patient satisfaction. We hypothesized that renovating the interior would make patients more satisfied with the quality of medical care. We performed a Pretest-Posttest analysis in a recently renovated single-practice primary care office in Grenchen, Switzerland. Before and after renovation, we distributed a questionnaire to assess patient satisfaction in four domains. We chose a Likert scale (1 = very poor to 6 = very good), and 12 quality indicators, and included two consecutive samples of patients presenting at the primary care office before (n = 153) and after (n = 153) interior design renovation. Response rate was high (overall 85 %). The sample was similar to the enlisted patient collective, but the sample population was older (60 years) than the collective (52 years). Patient satisfaction was higher for all domains after the office was renovated (p patient satisfaction, including satisfaction in domains otherwise unchanged. Physician skills and patient satisfaction sometimes depend on surrounding factors that may bias the ability of patients to assess the quality of medical care. These biases should be taken into account when quality assessment instruments are designed for patients.

In March 2016, the Latvian government approved a new support program for increasing energy efficiency in residential apartment buildings. For the support of renovation of apartment buildings in the period from 2016 to 2023, 166 470 588 EUR will be available. Different persons, such as energy auditors, designers, architects, project managers and builders, will be involved in the process of planning, development and implementation of building renovation. At the development stage of the building renovation project, special attention should be devoted to the first stage - energy audit and technical project development. The problem arises due to the fact that each of these individuals, during the development of technical building documentation, does not work as a completely unified system. The implementation of construction project planning and organisational management system is one of the most important factors to guarantee that the quality of building renovation project is ensured in accordance with the laws and regulatory standards. The paper studies mutual cooperation, professionalism and the role of information feedback of personnel involved in the planning stage of building renovation, which is an essential prerequisite for the renovation process in order to achieve high quality of work and reduce the energy performance indicator. The present research includes the analysis of different technical solutions and their impact on energy efficiency. Mutual harmonisation of technical specifications is also investigated.

There is a large potential for achieving energy savings in this sector, especially among the large number of single-family houses built in the 1960s and 1970s...... that the use of this approach produced a better renovation with a larger energy saving. The initial evaluation helped the house owners identify a maintenance backlog, and the use of an independent advisor helped ensure quality throughout the process. Renovations are too often carried out for just one purpose......: maintenance, to update functions or to reduce energy consumption. But a lot can be gained by combining these efforts, which can reduce expenses for planning and execution and avoid doing things twice.

Heating of dwellings represents a major policy challenge for the transition to a low carbon society. In Denmark, heating of dwellings represents about 25% of the total Danish final energy consumption and about 13% of the total CO2 emission. The majority of this is related to heating of older dwellings, and as the rate of replacement is low, the main potential for energy saving is to improve the energy efficiency of the existing dwelling stock through energy renovation. This paper provides an analysis of Danish experiences with energy labels (also known as the Energy Performance Certificate, EPC), which indicate the energy efficiency of buildings and include recommendations for improvements. The aim of the EPC is to motivate homeowners to do energy improvements. In Denmark, energy audit schemes date back to the early 1980s and energy rating of houses (energy labelling) was introduced in 1997. The long history of energy audit schemes and energy labelling makes Denmark an interesting case for the study of the experiences with and impact of this kind of policy measure. With the EU Energy Performance of Buildings Directive (EPBD) from 2002, an energy labelling scheme similar to the Danish scheme introduced in 1997 is now in use in all EU member states. The focus of this paper is on the homeowners' experience and use of the EPC and the key research questions are: How do the homeowners understand and use the EPC? Does the EPC have an influence on home energy renovation practices? The analysis is based on results from a survey of Danish homeowners who have purchased a home with an EPC within recent years. The Danish survey is part of the European project IDEAL EPBD, which was funded by the European Commission under the Intelligent Energy Europe programme and run from 2008 to 2011. The results indicate a rather limited influence of the EPC on Danish homeowners' home energy renovation practices. Also, the results show that even though most homeowners find the label

Building Brains has been set up by TNO as a cooperative and started September 21, 2009. The aim of the project was to answer the question how the energy consumption in the Netherlands can be reduced by 50% up to 2030 or how the built environment can be made energy-neutral. This issue of the magazine is dedicated to Building Brains project. It is often said that Smart defined ambitions and strict process management are important ingredients for successful realization of building projects. Sustainable real estate developments can be considered as highly ambitious projects. To find out how and why sustainable renovation projects actually became sustainable, a group of professionals systematically evaluated 21 leading Dutch real estate renovation projects. For each project they interviewed the client, consultant, architect and contractor. Based on the results it was concluded that a pre-defined (sustainability) ambition is not a necessity to realize a project that can be considered sustainable in practice. [Dutch] Building Brains is een door TNO opgezet samenwerkingsproject dat op 21 september 2009 van start ging. Het doel van het project is antwoord te geven op de vraag hoe tot 2030 het energiegebruik in Nederland kan worden gehalveerd of hoe de gebouwde omgeving energieneutraal kan worden gemaakt. Deze aflevering van het tijdschrift TVVL is vrijwel geheel gewijd aan het Building Brains project. Een jaar lang zijn de succes- en faalfactoren van duurzame renovatieprojecten onderzocht. Voor 21 projecten zijn in totaal 73 actoren geinterviewd.

Green eco-friendly housing includes approaches to reduce indoor air pollutant sources and to increase energy efficiency. Although sealing/tightening buildings can save energy and reduce the penetration of outdoor pollutants, an adverse outcome can be increased buildup of pollutants with indoor sources. The objective of this study was to determine the differences in the indoor air quality (IAQ) between green and non-green homes in low-income housing complexes. In one housing complex, apartments were renovated using green principles (n = 28). Home visits were conducted immediately after the renovation, and subsequently at 6 months and at 12 months following the renovation. Of these homes, eight homes had pre-renovation home visits; this allowed pre- and post-renovation comparisons within the same homes. Parallel visits were conducted in non-green (control) apartments (n = 14) in a nearby low-income housing complex. The IAQ assessments included PM{sub 2.5}, black carbon, ultrafine particles, sulfur, total volatile organic compounds (VOCs), formaldehyde, and air exchange rate. Data were analyzed using linear mixed-effects models. None of the indoor pollutant concentrations were significantly different between green and non-green homes. However, we found differences when comparing the concentrations before and after renovation. Measured immediately after renovation, indoor black carbon concentrations were significantly lower averaging 682 ng/m{sup 3} in post-renovation vs. 2364 ng/m{sup 3} in pre-renovation home visits (p = 0.01). In contrast, formaldehyde concentrations were significantly higher in post-renovated (0.03 ppm) than in pre-renovated homes (0.01 ppm) (p = 0.004). Questionnaire data showed that opening of windows occurred less frequently in homes immediately post-renovation compared to pre-renovation; this factor likely affected the levels of indoor black carbon (from outdoor sources) and formaldehyde (from indoor sources) more than the renovation status

Due to sustained economic growth in China over the last three decades, urbanization has been on a rapidly expanding track. In recent years, regional industrial relocations were also accelerated across the country from the east coast to the west inland. These changes have led to a large-scale redesign of urban infrastructures, including the drainage system. To help the reconstructed infrastructures towards a better sustainability, a tool is required for assessing the efficiency and environmental performance of different renovation schemes. This paper developed an integrated dynamic modeling tool, which consisted of three models for describing the sewer, the wastewater treatment plant (WWTP) and the receiving water body respectively. Three auxiliary modules were also incorporated to conceptualize the model, calibrate the simulations, and analyze the results. The developed integrated modeling tool was applied to a case study in Shenzhen City, which is one of the most dynamic cities and facing considerable challenges for environmental degradation. The renovation scheme proposed to improve the environmental performance of Shenzhen City's urban drainage system was modeled and evaluated. The simulation results supplied some suggestions for the further improvement of the renovation scheme.

The renovation or refurbishment is an important point in the life cycle of a building that makes it possible to achieve both environmental and climate protection goals and a higher quality of living of the inhabitants. However, lack of money often leads to a renovation that covers only the basic requirements, whereas measures that are valuable in a long term perspective like energy saving measures are not realised. Energy performance contracting (EPC) is widely used as an instrument to reduce long term operating costs significantly by guaranteed energy savings. An energy service company (ESCo) implements saving technologies, especially in the field of heating, HVAC, lighting and plug loads, and in particular in public buildings. It is the aim of this paper to investigate the possibilities to incorporate construction measures like building envelope insulation into standard energy performance contracting.For this purpose a qualitative survey is presented that was performed among experts and stakeholders in the business: ESCos, building owners and facility managers, representatives of construction companies and financing institutions were interviewed. The focus was on their experiences with such projects, on difficulties that arose or barriers that exist from their point of view and on the chances they perceived. This provides the basis for identifying restraints and supporting factors for the integration of contracting and constructional measures.Three pilot projects that have been renovated in Austria are outlined subsequently. They are evaluated with respect to the contractual network between the project partners, types of guarantees and financing issues. Special emphasis is put on the assignment of tasks and the cash flow between the project partners. Various constellations of trades acted as energy service provider: a general contractor, an energy supply company, a consortium of a builder and a plumber. The projects reveal some differences to the standard energy

Potential energy savings in renovation projects of residential and service buildings; Energiansaeaestoemahdollisuudet rakennuskannan korjaustoiminnassa

Energy Technology Data Exchange (ETDEWEB)

Heljo, J.; Vihola, J.

The study estimates the feasible energy savings potential in the 2010 building stock by 2050. The focus is on energy-saving measures related to renovation of residential and service buildings. The calculations were done by building types and age groups using the EKOREM calculation model. The calculations indicate the building types and structural elements where potential for savings exists. The study did not consider energy-saving measures related to changes in heating systems, electrical equipment, property maintenance or use habits. The study disproved the common belief that considerably more energy savings could be achieved faster by focussing on the existing building stock instead of new construction. That is mainly due the fact that it generally pays to implement structural energy-saving measures only when the targeted elements also require other significant repairs besides energy-efficiency improvements. Thus, energy renovations cannot be speeded up very much. The clearest exception are the extra insulations added to roof assemblies that are easy to implement. Attempts to save more energy in the building stock than can be achieved at a small additional cost in connection with needed renovations may multiply costs, and the saving in energy costs will not necessarily cover the additional investments. The efficiency of energy-saving measures can be affected by recommending or ordering use of more energy efficient windows, thicker extra insulations or more efficient ventilation heat recovery systems than the standard solution selected in connection with renovations. The goal of preserving the characteristics of buildings of cultural-historical or architectural value and the typical solutions and materials used in all buildings of a certain period limit the repair and renovation of structural elements. In the case of these buildings, improvement of energy efficiency can be considered in connection with the planning of renovations and the buildings' use and

Renzi, V.; Burgun, F. [Inst. National de l' Energie Solaire, Le Bourget du Lac (France)

2009-07-01

Buildings constitute 42.5 per cent of the energy consumption in Europe. As such, the building sector represents a high potential for innovation in terms of reducing global energy consumption. Since existing buildings represent a large part of the built environment, refurbishment is an important issue to consider. However, efficient processes of renovation must be well defined. France's National Institute of Solar Energy has developed a methodology to reduce consumption of primary energy use and decrease greenhouse gas emissions in the built environment, while increasing user comfort. The methodology places much emphasis on the health and comfort of occupants from the very beginning of the process. The methodology was developed to make the building renovation process more efficient by elaborating generic guidelines and tools. In this study, an office building from the 1970s was refurbished and monitored for both energy performance and comfort. The objective was to better understand the technological and psychosocial aspects involved in refurbishing an old building. Measurements were compared with the perception of the occupants. The impacts of human interaction on the building behaviour was also evaluated. 6 refs., 1 tab., 4 figs.

Measuring patient experience is key when assessing quality of care but can be biased: A perceptual bias occurs when renovations of the interior design of a general practitioner (GP) office improves how patients assessed quality of care. The aim was to assess the length of perceptual bias and if it could be reproduced after a second renovation. A GP office with 2 GPs in Switzerland was renovated twice within 3 years. We assessed patient experience at baseline, 2 months and 14 months after the first and 3 months after the second renovation. Each time, we invited a sample of 180 consecutive patients that anonymously graded patient experience in 4 domains: appearance of the office; qualities of medical assistants and GPs; and general satisfaction. We compared crude mean scores per domain from baseline until follow-up. In a multivariate model, we adjusted for patient's age, gender and for how long patients had been their GP. At baseline, patients aged 60.9 (17.7) years, 52% females. After the first renovation, we found a regression to the baseline level of patient experience after 14 months except for appearance of the office (pInterior renovation of a GP office probably causes a perceptual bias for >1 year that improves how patients rate quality of care. This bias could be reproduced after a second renovation strengthening a possible causal relationship. These findings imply to appropriately time measurement of patient experience to at least one year after interior renovation of GP practices to avoid environmental changes influences the estimates when measuring patient experience.

To evaluate the effectiveness of Preventing Obesity by Design (POD), a childcare center outdoor renovation intervention. Pre-post intervention evaluation. North Carolina licensed childcare centers (N = 27). Preschool children. Outdoor renovation, teacher training. Behavior mapping, Preschool Outdoor Environment Measurement Scale (POEMS), center director interview. Descriptive statistics, ordinary least squares and logistic regressions calculated to assess levels of association between environmental change, children's physical activity (PA), social behaviors, and environmental quality. Qualitative interview data analyzed to help understand intervention impact. Behavior mapping showed that site layout attributes, such as the form (i.e., "single loop" and "double loop") of pathways (functioning as circulation routes and wheeled toy settings), are associated with higher levels of PA. Teacher interaction was associated with decreased children's PA. Absence of teacher or lack of child/child interaction was associated with increased PA. POEMS assessment of environmental quality was higher after renovation. POEMS domains (Physical Space and Teacher/Caregiver Roles) were positively associated with PA. After renovation, 68% of center directors reported positive changes in children's behavior and 40% mentioned edible plant installations as greatest success. Built environment renovation of childcare center outdoors, including looped pathways installation, coupled with teacher training, may support increased PA. Renovation, including food gardens, may be a key to success for preschool health promotion and support change in childcare policy.

It includes an interpretation of the stylistic features of the Dao Wai building. Also, there was made a presumptive conclusion about the origins of the “Chinese Baroque”, which is now famous Dao Wai, combining European order architecture and far Eastern decorative tradition. Presumptive conclusion was based on the construction area observing in 2011-2016 and on the Chinese sources. As a result of renovation, there was formed a new public space with high tourism potential. Social value and status of the Dao Wai has significantly grown. The significant cost increase of real estate and provided services is an essential consequence of the gentrification method. There are were noted increased problems of the native people forced to move from the center to the outskirts of the city. Also, this article analyzes the current stage of the second phase design of Dao Wai renovation project and the perspectives for its implementation.

Success for energy efficient renovation of dwellings—Learning from private homeowners

International Nuclear Information System (INIS)

Risholt, Birgit; Berker, Thomas

2013-01-01

Large scale energy efficient renovation of buildings is one of the most important tools to realize the society's need of a more sustainable building stock. Most Norwegians own their own homes. Therefore private homeowners are a focus group for the government urging to accelerate the dwelling energy efficiency rates. Success factors were identified in the in-depth study of the decision process of eleven homeowners. Large differences in energy use due to the building's condition and the occupants' behavior was encountered in the sample. Only homeowners who were conscious consumers and did not trust expert advice or that had special knowledge due to their professions succeeded in realizing energy efficiency by renovation. Lack of knowledge, bad advice from craftsmen or priority to work that they can do themselves stopped other homeowners from implementing energy efficiency. Increased knowledge on all the gains from energy efficiency, the availability of attractive products and services as well as easy access to reliable advice on the better renovation solutions have a large potential to get more homeowners to make energy efficient choices in the process of renovation. Coordination of more of policy strategies including specific information and incentives are needed to facilitate this. - Highlights: • Private homeowners are a key group to increase the dwelling energy efficiency rates. • The annual energy use varies from 103 kW h/m 2 to 240 kW h/m 2 in similar dwellings. • Homeowners that are conscious consumers or have knowledge succeed in saving energy. • Access to relevant and reliable advice can get homeowners to realize energy savings. • Craftsmen could be mediators between available products and the specific building

Sewerage systems: Overflow problems and renovation methods

Energy Technology Data Exchange (ETDEWEB)

Tanttu, Unto [Plancenter Ltd. (Finland)

1987-12-15

Total investments in Finland (1984) spent on sewer systems were roughly FIM 590 million. A big share, about 14 % of this sum (FIM 82 million), was spent on rehabilitation of networks. But is this still enough? According to some evaluations the respective amount should be about FIM 500 million for rehabilitation only. So the question, how to keep the performance of sewer networks satisfactory in the future, is really important. The overflow problem is one of the most serious problems caused by old and improperly working sewer systems. Anyhow, several other aspects of a poor condition of sewers are to be seen: - excess hydraulic loading of treatment plants, - normal maintenance and operation (flushing, opening of clogs) increases, and is more expensive, - unexpected renovation works and interruptions in operation cause e.g. troubles in traffic, odour problems in the environment, hygienic hazards etc., - the performance of other underground networks (water pipes, district heating pipes etc.) may be threatened by earth crushings due to old sewers. In this paper a short description of these items is presented as well as a description of the sewer renovation methods used recently in Finland.

Sustainable renovation of residential buildings and the landlord/tenant dilemma

International Nuclear Information System (INIS)

Ástmarsson, Björn; Jensen, Per Anker; Maslesa, Esmir

2013-01-01

The landlord/tenant dilemma arises when the interests of landlords and tenants misalign and is one of the greatest barriers hindering the development of sustainable renovation of residential buildings in Europe. The aim of this research is to investigate how regulatory changes and contractual solutions can help solve the landlord/tenant dilemma in relation to sustainable renovation of residential buildings, and how the general awareness of sustainable renovation can be increased. Particular focus is on whether tools like energy performance contracting and energy labeling can help solve the landlord/tenant dilemma. The research was done in relation to the specific situation in Denmark, but theory, information and experiences from other countries were included. The results show that there are plenty of opportunities to overcome the landlord/tenant dilemma, but principal/agent problems can only be overcome with a package solution. In the Danish national context the package solution must consist of legislative changes, financial incentives and better dissemination of information. Therefore, an array of different tools must be integrated and used in cooperation to overcome the dilemma. - Highlights: • There are plenty of opportunities to overcome the landlord/tenant dilemma. • The principal/agent problems can only be overcome with a package solution. • An array of different tools must be integrated and used in cooperation. • Legislative changes, financial incentives and better dissemination of information

The appeal of the green deal: Empirical evidence for the influence of energy efficiency policy on renovating homeowners

International Nuclear Information System (INIS)

Pettifor, H.; Wilson, C.; Chryssochoidis, G.

2015-01-01

The Green Deal is a major new energy policy designed to support the diffusion of energy efficiency measures in UK homes. This paper provides one of the first empirical examinations of the Green Deal′s success in influencing homeowners’ renovation decisions. Using a repeated measures design in which households were questioned before and after the Green Deal′s launch in January 2013, we assess the policy′s success in raising awareness of energy efficiency. In particular, we test the effectiveness of the Green Deal′s positioning to overcome barriers to renovation among homeowners already interested in or considering energy efficiency measures. Using the innovation decision process (Rogers, 2003) as a conceptual framing of the renovation decision process, we examine whether new information on energy efficiency provided by the Green Deal strengthened intentions and its antecedents. We find that (1) energy efficiency is of potential appeal to all renovators regardless of their attitudes about energy efficiency, (2) energy efficiency opportunities need to be identified in the early stages of renovation when homeowners are thinking about ways to improve their home, and (3) homeowners’ intentions towards energy efficiency are weakened by uncertainty about financial benefits, helping to explain the relatively slow uptake of the Green Deal to-date. - Highlights: • Examines the impact of a major new energy policy, the Green Deal, on intentions towards energy efficiency. • 502 households questioned four months prior to, and seven months after the launch. • Renovating itself is mechanism through which households engage with the Green Deal. • Strengthening beliefs in energy savings accelerates intentions to renovate energy efficiently

Critical to the Hospital's rebuilding efforts have been its public partners at the federal, state, and local government levels who have made a major financial commitment to renovating the Hospital's research infrastructure. To date, the Hospital for Special Surgery (HSS) has been awarded a total of nearly $8.5 million to create and equip new, state-of-the-art laboratories for scientific investigations. The modernization of the Hospital's research facilities was jump-started in 1998 with a $950,000 seed grant from the National Institutes of Health (NIH) to renovate laboratories for immunology research in the Caspary Research Building. Coupled with a matching $5.5 million commitment from HSS, this infusion of NIH funding laid the groundwork for an overhaul of all of the Hospital's research space.

Perspectives on Near ZEB Renovation Projects for Residential Buildings: The Spanish Case

Directory of Open Access Journals (Sweden)

Faustino Patiño-Cambeiro

2016-08-01

Full Text Available EU regulations are gradually moving towards policies that reduce energy consumption and its environmental impact. To reach this goal, improving energy efficiency in residential buildings is a key action line. The European Parliament adopted the Near Zero-Energy Building (nZEB as the energy efficiency paradigm through Directive 2010/31/EU, but a common technical and legislative framework for energy renovations is yet to be established. In this paper, the nZEB definition by COHERENO was adopted to evaluate several energy renovation packages in a given building, which is also representative of the Spanish building stock. Global costs are calculated for all of them following EPBD prescriptions. Two economic scenarios are analysed: with entirely private funding and with the current public financial incentives, respectively. The results show the divergence between optimum solutions in terms of costs and of minimum CO2 footprint and maximum energy saving. Moreover, in the absence of enough incentives, some inefficient renovations could achieve a global cost close to the optimal cost. The optimum solution both in terms of energy performance and global costs was carried out and described.

This issue of the magazine is dedicated to Building Brains project. Four different renovation concepts are compared: energy-neutral renovation that involves the exclusive use of sustainable generated energy;.the application of the passive construction principles; the use of Double Skin Facades; and decentralized facade-integrated installation techniques. Following the results of this study two optimized refurbishment approaches for a zero energy office are designed. [Dutch] Building Brains is een door TNO opgezet samenwerkingsproject dat op 21 september 2009 van start ging. Het doel van het project is antwoord te geven op de vraag hoe tot 2030 het energiegebruik in Nederland kan worden gehalveerd of hoe de gebouwde omgeving energieneutraal kan worden gemaakt. Deze aflevering van het tijdschrift TVVL is vrijwel geheel gewijd aan het Building Brains project. Er is onderzocht hoe verschillende renovatieconcepten scoren. Er zijn vier renovatieconcepten met elkaar vergeleken: energie neutraal renoveren door middel van duurzame energieopwekking, toepassen van het passiefhuisprincipe, toepassen van een tweedehuidfacade en toepassen van een decentrale, gevel-geintegreerde installatie. Uit de studie kwamen twee geoptimaliseerde concepten voor een energieneutrale kantoorrenovatie naar voren.

2016-06-01

This study tested the association between school-wide measures of an authoritative school climate and high school dropout rates in a statewide sample of 315 high schools. Regression models at the school level of analysis used teacher and student measures of disciplinary structure, student support, and academic expectations to predict overall high school dropout rates. Analyses controlled for school demographics of school enrollment size, percentage of low-income students, percentage of minority students, and urbanicity. Consistent with authoritative school climate theory, moderation analyses found that when students perceive their teachers as supportive, high academic expectations are associated with lower dropout rates.

A two-factor method for appraising building renovation and energy efficiency improvement projects

International Nuclear Information System (INIS)

Martinaitis, Vytautas; Kazakevicius, Eduardas; Vitkauskas, Aloyzas

2007-01-01

The renovation of residential buildings usually involves a variety of measures aiming at reducing energy and building maintenance bills, increasing safety and market value, and improving comfort and aesthetics. A significant number of project appraisal methods in current use-such as calculations of payback time, net present value, internal rate of return or cost of conserved energy (CCE)-only quantify energy efficiency gains. These approaches are relatively easy to use, but offer a distorted view of complex modernization projects. On the other hand, various methods using multiple criteria take a much wider perspective but are usually time-consuming, based on sometimes uncertain assumptions and require sophisticated tools. A 'two-factor' appraisal method offers a compromise between these two approaches. The main idea of the method is to separate investments into those related to energy efficiency improvements, and those related to building renovation. Costs and benefits of complex measures, which both influence energy consumption and improve building constructions, are separated by using a building rehabilitation coefficient. The CCE is used for the appraisal of energy efficiency investments, while investments in building renovation are appraised using standard tools for the assessment of investments in maintenance, repair and rehabilitation

2001-07-01

The solar energy manifests itself in different forms and its application has been fundamental for the humankind development. These forms are known as renewable energies, since they are energy forms that are renewed or remade with time or that are so abundant on Earth, that they will last for hundreds or thousands of years, either we use them or not. The main advantage of the utilization of the renewable energies in comparison with hydrocarbons is the one of having smaller impact on the environment, which brings about the conservation of nonrenewable resources, and to postpone its exhaustion. They allow the distributed generation, diminishing the power losses in the transmission and distribution systems, which increases the overall efficiency. In addition they can be the drive for regional development and generation of employment, because when having applications in remote zones and being a field still not completely developed in Mexico, the possibility exists of enabling professionals and technicians. From the point of view of the power sector, the renewable energies extend the supply and availability of energy, making more flexible and independent the operation and reliability of the national power system. [Spanish] La energia solar se manifiesta de diversas formas y su aplicacion ha sido fundamental para el desarrollo de la humanidad. A estas formas se les conoce como energias renovables, ya que son formas de energia que se van renovando o rehaciendo con el tiempo o que son tan abundantes en la tierra, que perduraran por cientos o miles de anos, las usemos o no. La principal ventaja del aprovechamiento de las energias renovables en comparacion con los hidrocarburos es la de tener menor impacto al medio ambiente, lo que trae consigo la conservacion de recursos no renovables, y posponer su termino.

Full Text Available La producción de plásticos a nivel mundial presenta cifras abrumadoras debido a que tienen aplicaciones en diferentes campos, desde la medicina hasta la industria de empaques. Uno de los problemas radica en que la materia prima para preparar esos plásticos proviene de fuentes fósiles, los principales responsables de las emisiones de dióxido de carbono a la atmósfera y después de usar esos materiales se desechan y tardan varios años en descomponerse. Otro problema está enfocado hacia la agricultura e incluye los procesos que generan desechos orgánicos como la industria azucarera y del café, que pueden contaminar el medio ambiente sin tratamiento adecuado. Cada vez cobra más importancia reemplazar los plásticos convencionales por biomateriales cuyos sustratos de partida provengan de fuentes renovables, que sean biodegradables y que puedan tener aplicaciones similares a los materiales convencionales. Por ello, en este artículo se destacan los últimos avances en el área de los materiales a partir de recursos renovables, en especial de los polímeros biobasados, de su biodegradabilidad y sus aplicaciones, para generar curiosidad y propiciar la búsqueda de alternativas de aprovechamiento de las fuentes renovables en la obtención de nuevos biopolímeros.

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

KPI-Driven Methodology for Urban Renovation at District Level. Sustainable Strategic Urban Planning

Directory of Open Access Journals (Sweden)

Cristina Criado

2018-03-01

Full Text Available Sustainable urban renovation is characterized by multiple factors (e.g., technical, socio-economic, environmental and ethical perspectives, different spatial scales and a number of administrative structures that should address the evaluation of alternative scenarios or solutions. This defines a complex decision problem that includes different stakeholders where several aspects need to be considered simultaneously. In spite of the knowledge and experiences during the recent years, there is a need of methods that lead the decision-making processes. In response, a methodology based on a KPI-driven approach for urban renovation at district level is proposed in the European Smart City project CITyFiED. The methodology is a procedure with the energy efficiency as main pillar and the local authorities as client. It is composed of seven phases that ensures an effective dialogue among all the stakeholders, aiming to understand the objectives and needs of the city to deliver a set of customized Strategies for Sustainable Urban Renovation. In order to provide guidance and quantitative criteria, three levels of indicators are integrated into the approach: City Level Indicators (L1 at city & district level, Project Level KPIs (L2, and Impact Assessment Indicators at city level (L3.

Mosque, for Muslim, is not only a place for daily worshipping, however as a center of culture as well. It is an important and valuable building to be well managed. For a responsible department or institution (such as Religion or Plan Department in Indonesia), to practically manage a lot of mosques is not simple task to handle. The challenge is in relation to data number and characteristic problems tackled. Specifically for renovating and rehabilitating the damaged mosques, a decision to determine the first damaged mosque priority to be renovated and rehabilitated is problematic. Through two types of optimization method, simulated-annealing and hill-climbing, a decision support model for mosque renovation and rehabilitation was systematically constructed. The method fuzzy-logic was also operated to establish the priority of eleven selected parameters. The constructed model is able to simulate an efficiency comparison between two optimization methods used and suggest the most objective decision coming from 196 generated alternatives.

In Rostock Reutershagen should students learn in the future instead of in three different school sites in one school building; central energetically renovated and extended. The school is expected to reach the Plus Energy Standard, so there will be produced more energy than the building needs throughout the year. So far, the school consisted of a main building and two outbuildings. In future remains only the main building, the building shell is energetically renovated. The building incorporates a ventilation system. In addition two new buildings will be erected separated. The area between the buildings is provided with a transparent cover and used as an unheated intermediate climatic zone. The energy concept is based on the reduction of requirements. The supply of heat is effected by distance heating, the supply with electricity comes from the grid. The substitution is made by photovoltaic, an ORC system and by using wind energy. The innovative design of the new outer shell, including the existing external components, and the use of efficient building technologies leads to a maximum reduction of energy demand while expanding the possibilities of use.

Optimal Decision Model for Sustainable Hospital Building Renovation—A Case Study of a Vacant School Building Converting into a Community Public Hospital

Science.gov (United States)

Juan, Yi-Kai; Cheng, Yu-Ching; Perng, Yeng-Horng; Castro-Lacouture, Daniel

2016-01-01

Much attention has been paid to hospitals environments since modern pandemics have emerged. The building sector is considered to be the largest world energy consumer, so many global organizations are attempting to create a sustainable environment in building construction by reducing energy consumption. Therefore, maintaining high standards of hygiene while reducing energy consumption has become a major task for hospitals. This study develops a decision model based on genetic algorithms and A* graph search algorithms to evaluate existing hospital environmental conditions and to recommend an optimal scheme of sustainable renovation strategies, considering trade-offs among minimal renovation cost, maximum quality improvement, and low environmental impact. Reusing vacant buildings is a global and sustainable trend. In Taiwan, for example, more and more school space will be unoccupied due to a rapidly declining birth rate. Integrating medical care with local community elder-care efforts becomes important because of the aging population. This research introduces a model that converts a simulated vacant school building into a community public hospital renovation project in order to validate the solutions made by hospital managers and suggested by the system. The result reveals that the system performs well and its solutions are more successful than the actions undertaken by decision-makers. This system can improve traditional hospital building condition assessment while making it more effective and efficient. PMID:27347986

CPF (Chemical Processing Facility) was constructed at Nuclear Fuel Cycle Engineering Laboratories of JAEA (Japan Atomic Energy Agency) in 1980 as a basic research field where spent fuel pins from fast reactor (FR) and high level liquid waste can be dealt with. The renovation consists of remodeling of the CA-3 cell and the laboratory A, installation of globe boxes, hoods and analytical equipments to the laboratory C and the analytical laboratory. Also maintenance equipments in the CA-5 cell which had been out of order were repaired. The CA-3 cell is the main cell in which important equipments such as a dissolver, a clarifier and extractors are installed for carrying out the hot test using the irradiated FR fuel. Since the CPF had specialized originally in the research function for the Purex process, it was desired to execute the research and development of such new, various reprocessing processes. Formerly, equipments were arranged in wide space and connected with not only each other but also with utility supply system mainly by fixed stainless steel pipes. It caused shortage of operation space in flexibility for basic experimental study. Old equipments in the CA-3 cell including vessels and pipes were removed after successful decontamination, and new equipments were installed conformably to the new design. For the purpose of easy installation and rearranging the experimental equipments, equipments are basically connected by flexible pipes. Since dissolver is able to be easily replaced, various dissolution experiments is conducted. Insoluble residue generated by dissolution of spent fuel is clarified by centrifugal. This small apparatus is effective to space-saving. Mini mixer settlers or centrifugal contactors are put on to the prescribed limited space in front of the backside wall. Fresh reagents such as solvent, scrubbing and stripping solution are continuously fed from the laboratory A to the extractor by the reagent supply system with semi-automatic observation

The role of interfacial layers in the enhanced thermal conductivity of nanofluids: A renovated Hamilton-Crosser model

International Nuclear Information System (INIS)

Yu, W; Choi, S.U.S.

2004-01-01

We previously developed a renovated Maxwell model for the effective thermal conductivity of nanofluids and determined that the solid/liquid interfacial layers play an important role in the enhanced thermal conductivity of nanofluids. However, this renovated Maxwell model is limited to suspensions with spherical particles. Here, we extend the Hamilton--Crosser model for suspensions of nonspherical particles to include the effect of a solid/liquid interface. The solid/liquid interface is described as a confocal ellipsoid with a solid particle. The new model for the three-phase suspensions is mathematically expressed in terms of the equivalent thermal conductivity and equivalent volume fraction of anisotropic complex ellipsoids, as well as an empirical shape factor. With a generalized empirical shape factor, the renovated Hamilton--Crosser model correctly predicts the magnitude of the thermal conductivity of nanotube-in-oil nanofluids. At present, this new model is not able to predict the nonlinear behavior of the nanofluid thermal conductivity

Barriers and Potential Solutions for Energy Renovation of Buildings in Denmark

Directory of Open Access Journals (Sweden)

Niels I. Meyer

2014-02-01

Full Text Available Buildings account for a substantial part of the total energy consumption. In Denmark this number is about 40 % and this is approximately the same in most industrial countries. On this background there is an urgent need to develop strategies for reducing the energy demand in the building sector. Renovation of existing buildings must have high priority as houses often last for 50 to 100 years, while the time perspective for the desired transformation to low-energy houses is less than 30 years in order to mitigate global warming and avoid irreversible tipping-points. The only sustainable energy supply in the perspective of centuries is renewable energy provided by the sun and exploited in the form of solar heat, solar electricity (PVs, wind power, hydropower, wave power, and some types of biomass etc. A future dominating role of intermittent renewable sources requires new integrated systems thinking on both the supply and demand side for heat, electricity and transport. Implementing such Smart Energy Systems requires integrated strategic energy planning on the national and local level. With the fundamental changes in the energy supply technologies expected during the coming years, it is important to synchronize investments in energy conservation measures with investments in the supply side, in order to avoid overinvestment in supply systems and thus to minimize the total costs of the transformation to Smart Energy Systems. This paper highlights some of the most important barriers for renovation of existing buildings in Denmark and points to policies for overcoming these barriers. Some of the policies have been presented in the reports of a recent Danish research project (CEESA

[Purpose] This study aimed to compare physical activities between junior high school and high school female football players in order to explain the factors that predispose to a higher incidence of sports injuries in high school female football players. [Subjects and Methods] Twenty-nine female football players participated. Finger floor distance, the center of pressure during single limb stance with eyes open and closed, the 40-m linear sprint time, hip abduction and extension muscle strength and isokinetic knee flexion and extension peak torque were measured. The modified Star Excursion Balance Test, the three-steps bounding test and three-steps hopping tests, agility test 1 (Step 50), agility test 2 (Forward run), curl-up test for 30 seconds and the Yo-Yo intermittent recovery test were performed. [Results] The high school group was only significantly faster than the junior high school group in the 40-m linear sprint time and in the agility tests. The distance of the bounding test in the high school group was longer than that in the junior high school group. [Conclusion] Agility and speed increase with growth; however, muscle strength and balance do not develop alongside. This unbalanced development may cause a higher incidence of sports injuries in high school football players.

Highlights: • Energy saving measures can be cost-effective as part of a planned renovation. • Primary energy consumption, non-renewable energy consumption and CO_2 emissions are assessed for different electricity mixes. • EAHP can be a cost-effective and environmentally beneficial complement to district heating. • EAHP has lower LCC and significantly shorter payback time than ventilation with heat recovery. • Low-temperature ventilation radiators improve the COP of the heat pump. - Abstract: Renovation of existing buildings is important in the work toward increased energy efficiency and reduced environmental impact. The present paper treats energy renovation measures for a Swedish district heated multi-family house, evaluated through dynamic simulation. Insulation of roof and façade, better insulating windows and flow-reducing water taps, in combination with different HVAC systems for recovery of heat from exhaust air, were assessed in terms of life cycle cost, discounted payback period, primary energy consumption, CO_2 emissions and non-renewable energy consumption. The HVAC systems were based on the existing district heating substation and included mechanical ventilation with heat recovery and different configurations of exhaust air heat pump. Compared to a renovation without energy saving measures, the combination of new windows, insulation, flow-reducing taps and an exhaust air a heat pump gave up to 24% lower life cycle cost. Adding insulation on roof and façade, the primary energy consumption was reduced by up to 58%, CO_2 emissions up to 65% and non-renewable energy consumption up to 56%. Ventilation with heat recovery also reduced the environmental impact but was not economically profitable in the studied cases. With a margin perspective on electricity consumption, the environmental impact of installing heat pumps or air heat recovery in district heated houses is increased. Low-temperature heating improved the seasonal performance factor of the

A District Approach to Building Renovation for the Integral Energy Redevelopment of Existing Residential Areas

Directory of Open Access Journals (Sweden)

Mira Conci

2017-05-01

Full Text Available Building energy renovation quotas are not currently being met due to unfavorable conditions such as complex building regulations, limited investment incentives, historical preservation priorities, and technical limitations. The traditional strategy has been to incrementally lower the energy consumption of the building stock, instead of raising the efficiency of the energy supply through a broader use of renewable sources. This strategy requires an integral redefinition of the approach to energy building renovations. The joint project SWIVT elaborates on a district redevelopment strategy that combines a reduction in the energy demand of existing buildings and their physical interconnection within a local micro-grid and heating network. The district is equipped with energy generation and distribution technologies as well as hybrid thermal and electrical energy storage systems, steered by an optimizing energy management controller. This strategy is explored through three scenarios designed for an existing residential area in Darmstadt, Germany, and benchmarked against measured data. Presented findings show that a total primary energy balance at least 30% lower than that of a standard building renovation can be achieved by a cluster of buildings with different thermal qualities and connected energy generation, conversion, and storage systems, with only minimal physical intervention to existing buildings.

The renovation of a building will certainly affect the quality of air in the vicinity of where associated activities were undertaken, this includes the quality of air inside the building. Indoor air pollutants such as particulate matter, heavy metals, and fine fibers are likely to be emitted during renovation work. This study was conducted to determine the concentration of heavy metals, asbestos and suspended particulates in the Biology Building, at the Universiti Kebangsaan, Malaysia (UKM). Renovation activities were carried out widely in the laboratories which were located in this building. A low-volume sampler was used to collect suspended particulate matter of a diameter size less than 10 μm (PM₁₀) and an air sampling pump, fitted with a cellulose ester membrane filter, were used for asbestos sampling. Dust was collected using a small brush and scope. The concentration of heavy metals was determined through the use of inductively coupled plasma-mass spectroscopy and the fibers were counted through a phase contrast microscope. The concentrations of PM₁₀ recorded in the building during renovation action (ranging from 166 to 542 μg m⁻³) were higher than the value set by the Department of Safety and Health for respirable dust (150 μg m⁻³). Additionally, they were higher than the value of PM₁₀ recorded in indoor environments from other studies. The composition of heavy metals in PM₁₀ and indoor dust were found to be dominated by Zn and results also showed that the concentration of heavy metals in indoor dust and PM₁₀ in this study was higher than levels recorded in other similar studies. The asbestos concentration was 0.0038 ± 0.0011 fibers/cc. This was lower than the value set by the Malaysian Department of Occupational, Safety and Health (DOSH) regulations of 0.1 fibers/cc, but higher than the background value usually recorded in indoor environments. This study strongly suggests that renovation issues need to be considered seriously

Highlights: ► We developed a waste estimation system leveraging the BIM technology. ► The system can calculate waste disposal charging fee and pick-up truck demand. ► We presented an example scenario demonstrating this system. ► Automatic, time-saving and wide applicability are the features of the system. - Abstract: Due to the rising worldwide awareness of green environment, both government and contractors have to consider effective construction and demolition (C and D) waste management practices. The last two decades have witnessed the growing importance of demolition and renovation (D and R) works and the growing amount of D and 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 and 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

Gasper, Joseph; DeLuca, Stefanie; Estacion, Angela

2014-01-01

Youth who switch schools are more likely to demonstrate a wide array of negative behavioral and educational outcomes, including dropping out of high school. However, whether switching schools actually puts youth at risk for dropout is uncertain, since youth who switch schools are similar to dropouts in their levels of prior school achievement and engagement, which suggests that switching schools may be part of the same long-term developmental process of disengagement that leads to dropping out. Using data from the National Longitudinal Survey of Youth 1997, this study uses propensity score matching to pair youth who switched high schools with similar youth who stayed in the same school. We find that while over half the association between switching schools and dropout is explained by observed characteristics prior to 9th grade, switching schools is still associated with dropout. Moreover, the relationship between switching schools and dropout varies depending on a youth's propensity for switching schools. PMID:25554706

Full Text Available The purpose of this study was to examine the relationship between the size of Alabama’s public high schools, selected school quality and financial indicators, and their students’ performance on standardized exams. When the socioeconomic level of the student bodies is held constant, the size of high schools in Alabama has relatively little relationship with 11th grade student (both regular and special education performance on the reading and math portions of the Alabama High School Graduation Exam (AHSGE. High schools’ average daily attendance rates and pupil-to-computer (and computer with Internet connections ratios do not vary in accordance with school size. Higher percentages of highly qualified teachers are found in Alabama’s largest high schools. There was very little difference in the percentage of teachers with a master’s degree or above across school size categories. Very little difference exists across size categories in regard to mean expenditures per pupil (range = $7,322 to $7,829. However, districts of the large high schools exert over twice the effort of those with small high schools (3.2 mills to 1.5 mills and approximately 50 percent greater local effort than the districts of the medium-size high schools.

25% of US households utilize onsite wastewater treatment systems (OWTS) for wastewater management. Advanced technologies were designed to overcome the inadequate wastewater treatment by conventional OWTS in critical shallow water table areas, such as coastal zones, in order to protect ground water quality. In addition to the septic tank and soil drainfield that comprise a conventional OWTS, advanced systems claim improved water renovation with the addition of sand filtration, timed dosing controls, and shallow placement of the infiltrative zone. We determined water quality renovation functions under current water table and temperature conditions, in anticipation of an experiment to measure OWTS response to a climate change scenario of 30-cm increase in water table elevation and 4C temperature increase. Replicate (n=3) intact soil mesocosms were used to evaluate the effectiveness of drainfields with a conventional wastewater delivery (pipe-and-stone) compared to two types of pressurized, shallow narrow drainfield. Results under steady state conditions indicate complete removal of fecal coliform bacteria, phosphorus and BOD by all soil-based systems. By contrast, removal of total nitrogen inputs was 16% in conventional and 11% for both advanced drainfields. Effluent waters maintained a steady state pH between 3.2 - 3.7 for all technologies. Average DO readings were 2.9mg/L for conventional drainfield effluent and 4.6mg/L for advanced, showing the expected oxygen uptake with shallow placement of the infiltrative zone. The conventional OWTS is outperforming the advanced with respect to nitrogen removal, but renovating wastewater equivalently for all other contaminants of concern. The results of this study are expected to facilitate development of future OWTS regulation and planning guidelines, particularly in coastal zones and in the face of a changing climate.

At-risk high school seniors: Science remediation for Georgia's High School Graduation Test

Science.gov (United States)

Carroll, Carolyn M.

State departments of education have created a system of accountability for the academic achievement of students under the mandate of the No Child Left Behind Act of 2001. The Georgia Department of Education established the Georgia High School Graduation Test (GHSGT) as their method of evaluating the academic achievement of high school students. The GHSGT consist of five sections and students must pass all five sections before students they are eligible to receive a diploma. The purpose of the study was to examine the effects of teacher-lead and computer based remediation for a group of high school seniors who have been unsuccessful in passing the science portion of the GHSGT. The objectives of this study include (a) Identify the most effective method of remediation for at-risk students on the science section of the GHSGT, and (b) evaluate the methods of remediation for at-risk students on the science section of GHSGT available to high school students. The participants of this study were at-risk seniors enrolled in one high school during the 2007-2008 school year. The findings of this research study indicated that at-risk students who participated in both types of remediation, teacher-led and computer-based, scored significantly higher than the computer-based remediation group alone. There was no significant relationship between the test scores and the number of times the students were tested.

Adolescents who do not get enough sleep are more likely to be overweight; not engage in daily physical activity; suffer from depressive symptoms; engage in unhealthy risk behaviors such as drinking, smoking tobacco, and using illicit drugs; and perform poorly in school. However, insufficient sleep is common among high school students, with less than one third of U.S. high school students sleeping at least 8 hours on school nights. In a policy statement published in 2014, the American Academy of Pediatrics (AAP) urged middle and high schools to modify start times as a means to enable students to get adequate sleep and improve their health, safety, academic performance, and quality of life. AAP recommended that "middle and high schools should aim for a starting time of no earlier than 8:30 a.m.". To assess state-specific distributions of public middle and high school start times and establish a pre-recommendation baseline, CDC and the U.S. Department of Education analyzed data from the 2011-12 Schools and Staffing Survey (SASS). Among an estimated 39,700 public middle, high, and combined schools* in the United States, the average start time was 8:03 a.m. Overall, only 17.7% of these public schools started school at 8:30 a.m. or later. The percentage of schools with 8:30 a.m. or later start times varied greatly by state, ranging from 0% in Hawaii, Mississippi, and Wyoming to more than three quarters of schools in Alaska (76.8%) and North Dakota (78.5%). A school system start time policy of 8:30 a.m. or later provides teenage students the opportunity to achieve the 8.5-9.5 hours of sleep recommended by AAP and the 8-10 hours recommended by the National Sleep Foundation.

2018-01-01

Maltreated youth have higher rates of school dropout than their non-maltreated peers. School connectedness is a modifiable predictor of school success. We hypothesized maltreated youth's school connectedness (supportive relationships with adults at school and participation in school clubs) would be positively associated with high school graduation. We included youth with at least one Child Protective Services (CPS) report by age twelve from Longitudinal Studies of Child Abuse and Neglect, a prospective cohort study. Participation in extracurricular activities and adult relationships reported at age 16, high school graduation/General Education Development (GED) status reported at age 18, and demographics were provided by youth and caregivers. Maltreatment data were coded from CPS records. The outcome was graduation/receipt of GED. Multivariable logistic regressions examined the association between school connectedness and graduation/receipt of GED, controlling for confounders. In our sample of 318 maltreated youth, 73.3% graduated. School club was the only activity with a statistically significant association with graduation in bivariate analysis. Having supportive relationships with an adult at school was not significantly associated with graduation, though only 10.7% of youth reported this relationship. Maltreated youth who participated in school clubs had 2.54 times the odds of graduating, adjusted for study site, gender, poverty status, caregiver high school graduation status, and age at first CPS report (95% CI: [1.02, 6.33]). Few maltreated youth reported relationships with adults at school, and additional efforts may be needed to support these vulnerable youth. School club participation may represent an opportunity to modify maltreated youth's risk for school dropout. Copyright © 2017 Elsevier Ltd. All rights reserved.

Final report of the pre - investigation phase. Project on the establishment and renovation of renewable energy production facilities in Northern Poland

The project for the erection of a windmill park and the renovation/modernisation of the hydro power plants reached with the finishing of the pre-investigation a milestone. The results of the investigations show that the project is fully corresponding with both EU and polish politic aims of increased utilisation of renewable energy sources for electricity production. Further the pre-investigation notified, that in Poland there exists a lack of experience of the utilisation of wind for electricity production, as there exists only 12 windmill/windmill parks, so that the project is evaluated to have a high demonstration effect on the production of renewable energy based on wind. During the pre-investigation there were elaborated among others feasibility studies on the erection of the windmill park and the renovation of the hydro power plants. The economic feasibility calculations on both parts of the project, found that erection of the windmill park and the renovation of the hydro power plants are fully feasible under the existing conditions. It is foreseen that KEW, the local electricity production company as investor will obtain a loan under the Danish environmental soft loan program for Eastern Europe for the equipment and installation of the equipment. Associated specialist work is applied for support by the Danish Environmental Agency and the Danish Energy Agency. That these institutions and the Danish State Export Credit Agency (EKF) approve their principal willingness to support this project is the next necessary step for the projects implementation. (au)

Renovation of the 'old' NPP units as an economically effective way of nuclear power development

In the process of nuclear power development there comes a phase when the old' power-units, which reactor installations have expired the designed and extended service lifetime are withdrawn from operating. At this phase in the case of the same annual investments into nuclear power, the increase of the total set up capacity of the nuclear power will be terminated because introduction of capacities due to construction of 'new' power-units only compensates for the reduction of capacities caused by withdrawing from operating the 'old' power-units. Along with this, taking into account a sizeable difference in the service lifetime of the nuclear steam supplying systems and the rest infrastructure of the nuclear power plants, it is an opportunity to find the solution to the problem of compensating for the withdrawn capacities without considerable increasing the annual investments. This opportunity is connected with use of the innovative nuclear power technology based on multipurpose small power modular fast reactors with lead-bismuth coolant for replacement of the withdrawn capacities (renovation of power-units). The features of the innovative nuclear power technology based on the SVBR-76/100 reactor installations, the results of the technical and economical investigations that demonstrate the high economical efficiency of use of the renovation technology using the SVBR-75/100 reactor modules are presented in the Paper.

Where Sustainable School Meets the ‘Tthird Teacher’: Primary School Case Study From Barcelona, Spain

Directory of Open Access Journals (Sweden)

Marta Brkovic

2015-07-01

Full Text Available Participatory evaluation of aspiring sustainable schools and their pedagogical potential has recently come into focus. A few authors have made a significant start in examining schools as both environmentally and socially sustainable environments, which might simultaneously represent the ‘third teacher’. However, discussion around this idea is new in Spain. This paper describes a participatory post-occupancy study conducted with teachers and pupils in Fort Pienc School, Barcelona, Spain. Findings reveal the pedagogical potential of the school’s spaces and fabric, characterised as ‘sustainable’, and highlight the aspects that the research participants feel are performing and underperforming. The paper concludes that if we want sustainable schools to be a strategy for renovating the educational process and for leading us towards a better tomorrow globally and locally,  new models for exploring the pedagogical potential of sustainable schools should be developed and the efforts of all relevant parties synchronised; from architects to governments, from pupils to teachers.

Adoption of innovative energy systems in social housing: Lessons from eight large-scale renovation projects in The Netherlands

International Nuclear Information System (INIS)

Hoppe, Thomas

2012-01-01

Thanks to new insights on the impacts that dwellings have throughout their life cycles, there has been increased attention to retrofitting innovative energy systems (IES) in existing housing. This paper uses an explorative case study design to gain more knowledge about the governance aspects of this under-researched topic. The central research question is: Which factors influence the adoption of innovative energy systems in social housing sites during renovation projects? To answer this question, eight large-scale renovation projects in The Netherlands were investigated. These case studies allowed the identification of barriers, enabling factors and perspectives from three main actors—housing associations, tenants and local authorities. It turns out that adopting IES encounters many barriers: lack of trust between project partners, delay in project progress, financial feasibility considerations, lack of support from tenants, lengthy legal permit procedures, over-ambitious project goals, poor experiences in previous projects, and IES ambitions that are not taken serious by key decision-makers. Furthermore, IES were only successfully fitted in three of the eight projects. Moreover, ambitions were lowered as the projects progressed in all the cases investigated. The study calls for further systematic, in-depth comparison of fitting IES in large-scale renovation projects in social housing. - Highlights: ► Attention to adoption of innovative energy systems in social housing. ► Several non-technical factors influence adoption. ► In-depth analysis of eight local-level renovation projects. ► Ambitions are lowered as projects progress. ► Barriers: financial feasibility, over-ambitious goals, delay, lack of trust.

Tips for cleanroom construction and renovation.

Mixon, William; Huffman, Lanny

2009-01-01

The installation or renovation of a cleanroom is an increasing priority among compounders who, to offer sterile preparations, must comply with the most recent version of United States Pharmacopeia revised General Chapter 797 guidelines. To upgrade their pharmacy facilites, many compounders have worked successfully with a large-scale mechanical engineering firm or a specialized construction company dedicated to cleanroom installation. However, a qualified local mechanical contractor with design capability is a valuable and often overlooked resource for the construction of customized stae-of-the-art cleanrooms. In this report, we describe the installation of such a facility in a busy pharmacy and suggest ways in which compounding pharmacists can identify competent local contractors and control the cost of construction and upgrades. The addition of a cleanroom has enabled The Compounding Pharmacy in Hickory, North Carolina, to achieve accreditation from the Pharmacy Compounding Accreditation Board.

The influence of prefabricated pipe cement coatings and those made during pipe renovation on drinking water quality

Directory of Open Access Journals (Sweden)

Młyńska Anna

2017-01-01

Full Text Available Nowadays, cement coatings are often used as an anticorrosion protection of the internal surfaces of manufactured ductile iron water pipes. The protective cement linings are also commonly used for old water pipe renovation. In both cases, the cement lining is an excellent anticorrosion protection of the pipelines, effectively separating the pipe wall from the flowing water. Moreover, cement linings protect the pipelines not only by a mechanical barrier, but also by a chemical barrier creating a highly alkaline environment in water contact with the metal pipe wall. In addition, cement coatings have an ability for so-called self-regeneration and provide the improvement of hydraulic conditions inside the pipelines. In turn, the differences between the analysed cement coatings mainly depend on the types of cements used and techniques of cement mortar spraying. As was expected, they influence the quality of water having contact with the coating. A comparison of the impact of cement coatings manufactured in factories and sprayed on building sites during the renovation on drinking water quality parameters was performed in the study. The experiments were conducted in laboratory conditions, using the test stands prepared for this purpose. The results include analysis of selected water quality parameters for the samples contacting with cement mortar and collected during the investigation.

The advanced spent fuel conditioning process facility (ACPF) of the irradiated materials examination facility (IMEF) at the Korea Atomic Energy Research Institute (KAERI) has been renovated to implement a lab scale electrolytic reduction process for pyroprocessing. The interior and exterior structures of the ACPF hot cell have been modified under the current renovation project for the experimentation of the electrolytic reduction process using spent nuclear fuel. The most important aspect of this renovation was the installation of the argon compartment within the hot cell. For the design and system implementation of the argon compartment system, a full-scale mock-up test and a three-dimensional (3D) simulation test were conducted in advance. The remodeling and repairing of the process cell (M8a), the maintenance cell (M8b), the isolation room, and their utilities were also planned through this simulation to accommodate the designed argon compartment system. Based on the considered refurbishment workflow, previous equipment in the M8 cell, including vessels and pipes, were removed and disposed of successfully after a zoning smear survey and decontamination, and new equipment with advanced functions and specifications were installed in the hot cell. Finally, the operating area and isolation room were also refurbished to meet the requirements of the improved hot cell facility.

Full Text Available Abstract Objectives This study examined associations between high school students' lunch patterns and vending machine purchases and the school food environment and policies. Methods A randomly selected sample of 1088 high school students from 20 schools completed surveys about their lunch practices and vending machine purchases. School food policies were assessed by principal and food director surveys. The number of vending machines and their hours of operation were assessed by trained research staff. Results Students at schools with open campus policies during lunchtime were significantly more likely to eat lunch at a fast food restaurant than students at schools with closed campus policies (0.7 days/week vs. 0.2 days/week, p Conclusion School food policies that decrease access to foods high in fats and sugars are associated with less frequent purchase of these items in school among high school students. Schools should examine their food-related policies and decrease access to foods that are low in nutrients and high in fats and sugars.

Chevalier, V.; Mirotta, S.; Guillot, J.; Biard, B.

2018-01-01

The CABRI experimental pulse reactor, located at the Cadarache nuclear research center, southern France, is devoted to the study of Reactivity Initiated Accidents (RIA). For the purpose of the CABRI International Program (CIP), managed and funded by IRSN, in the framework of an OECD/NEA agreement, a huge renovation of the facility has been conducted since 2003. The Cabri Water Loop was then installed to ensure prototypical Pressurized Water Reactor (PWR) conditions for testing irradiated fuel rods. The hodoscope installed in the CABRI reactor is a unique online fuel motion monitoring system, operated by IRSN and dedicated to the measurement of the fast neutrons emitted by the tested rod during the power pulse. It is one of the distinctive features of the CABRI reactor facility, which is operated by CEA. The system is able to determine the fuel motion, if any, with a time resolution of 1 ms and a spatial resolution of 3 mm. The hodoscope equipment has been upgraded as well during the CABRI facility renovation. This paper presents the main outcomes achieved with the hodoscope since October 2015, date of the first criticality of the CABRI reactor in its new Cabri Water Loop configuration. Results obtained during reactor commissioning phase functioning, either in steady-state mode (at low and high power, up to 23 MW) or in transient mode (start-up, possibly beyond 20 GW), are discussed.

High-Performance Schools: Affordable Green Design for K-12 Schools; Preprint

Energy Technology Data Exchange (ETDEWEB)

Plympton, P.; Brown, J.; Stevens, K.

2004-08-01

Schools in the United States spend $7.8 billion on energy each year-more than the cost of computers and textbooks combined, according to a 2003 report from the National Center for Education Statistics. The U.S. Department of Energy (DOE) estimates that these high utility bills could be reduced as much as 25% if schools adopt readily available high performance design principles and technologies. Accordingly, hundreds of K-12 schools across the country have made a commitment to improve the learning and teaching environment of schools while saving money and energy and protecting the environment. DOE and its public- and private-sector partners have developed Energy Design Guidelines for High Performance Schools, customized for nine climate zones in U.S. states and territories. These design guidelines provide information for school decision makers and design professionals on the advantages of energy efficiency and renewable energy designs and technologies. With such features as natural day lighting, efficient electric lights, water conservation, and renewable energy, schools in all types of climates are proving that school buildings, and the students and teachers who occupy them, are indeed high performers. This paper describes high performance schools from each of the nine climate zones associated with the Energy Design Guidelines. The nine case studies focus on the high performance design strategies implemented in each school, as well as the cost savings and benefits realized by students, faculty, the community, and the environment.

The conducted experiments were aimed at analyzing partitions of 120 mm brick mounted gypsum panels while other walls were 520 mm thick and plastered on both sides. Under natural conditions, sound insulation factors of facades were measured and compared according to comfort classes. The obtained results revealed that thick brick walls of 520 mm insulated the sound of 58 decibels (dB (class B. In contrast, 120 mm brick masonry partition reduced sound only to 48 dB which is class E and agrees with the lowest class of sound insulation. We also calculated the sound insulation factor applying three formulas considering the mass law of sound insulation and comparing it with other previous studies. The paper examines and discusses the findings of the performed calculations and measurements.Article in Lithuanian

Credentialing high school psychology teachers.

Science.gov (United States)

Weaver, Kenneth A

2014-09-01

The National Standards for High School Psychology Curricula (American Psychological Association, 2013b) require a teacher with considerable psychology content knowledge to teach high school psychology courses effectively. In this study, I examined the initial teaching credential requirements for high school psychology teachers in the 50 states plus the District of Columbia. Thirty-four states (the District of Columbia is included as a state) require the social studies credential to teach high school psychology. An analysis of the items on standardized tests used by states to validate the content knowledge required to teach social studies indicates little or no presence of psychology, a reflection of psychology's meager presence in the social studies teacher preparation curricula. Thus, new teachers with the social studies teaching credential are not prepared to teach high school psychology according to the National Standards. Approval of The College, Career, and Civic Life (C3) Framework for Social Studies State Standards: Guidance for Enhancing the Rigor of K-12 Civics, Economics, Geography, and History (National Council for the Social Studies, 2013) presents an opportunity to advocate for establishing a psychology credential in the 34 states.

Renovating Charity Hospital or building a new hospital in post-Katrina New Orleans: economic rationale versus political will.

Science.gov (United States)

Leleu, Hervé; Moises, James; Valdmanis, Vivian Grace

2013-02-01

Since September 2005, Charity Hospital of New Orleans has been closed due to Hurricane Katrina. A debate following the closing arose about whether this public hospital should be renovated or a new medical center affiliated with the Louisiana State University should be built. Using academic literature, government statistics, and popular press reports, we describe the economic implications that support the view that Charity Hospital should have been renovated. We also address why this policy was not pursued by demonstrating the influence politics and individual stakeholders (specifically, Louisiana State University) had on the eventual policy pursued. In this commentary we also note the political identity movement away from public-sector provision of services to private-sector interests.

2015-12-01

Full Text Available La creciente demanda de las necesidades sociales a nivel global, impulsada por los hábitos de vida y la forma en la que se organizan las regiones ha llevado al crecimiento paralelo de la industria y con ello al creciente aumento del consumo de energía. Este artículo de investigación reflexiona acerca de la relevancia que tienen las energías renovables para la seguridad energética, teniendo en cuenta la inestabilidad de los precios del petróleo y su influencia en el mercado de los hidrocarburos como fuente primaria de energía. Se evidencian los avances que han tenido las tecnologías de energías renovables a nivel global, regional y local y el rol que juegan en la independencia energética y en la mitigación del impacto ambiental. Se concluye que las naciones deben buscar la optimización de las energías renovables desde los ámbitos: local, regional y global propendiendo por su uso adecuado desde la legislación. El futuro de las energías renovables está dado por la rentabilidad, ya que para que el uso de éstas siga creciendo, deben seguir atrayendo capital lo cual significa que los inversores deben ver una rentabilidad competitiva. Otra recomendación importante es la integración de la energía renovable en la red, incluyendo fuentes de generación intermitentes e incluso imprevisibles. 

The Phenomenon of Trust in Flat Owners’ Collective Renovation Strategies in Estonia

Directory of Open Access Journals (Sweden)

Liis Ojamäe

2015-12-01

Full Text Available Mobilising fl at owners into renovating residential blocks in post-socialist countries has been a complicated process. Evidence from Estonia shows that the success of collective renewal strategies depends not only on economic issues but also on ways investments are organised and, signifi cantly, the relationship of trust between diff erent actors. The paper aims at conceptualising the issue of institutional trust upon the experience of urban housing renewal in Estonia. It is contended that trust is crucial for the joint decision-making in a block as well as for facilitating negotiations between fl at owners’ associations, local municipalities and market actors. The paper draws on three qualitative studies conducted in Estonia during the 2000s, which allow asserting that trust towards new strategies of housing renewal can be achieved and maintained by ‘best practices’, which by concentrating expert knowledge also denote direct communication between experts and fl at owners. While it is important to raise the residents’ technical knowledgeability, it is indispensable to develop abilities to manage and communicate the renovation process between diff erent parties. The public sector is conceived to be a central actor in sustaining trust between actors who have no previous positive experience from collective residential strategies

Although high school graduation is important for living conditions and health throughout life, many students do not complete. In Norway's northern most county, Finnmark, up to 45% of students do not complete high school. Contrary to prior research that has primarily focused on causes for dropout, this study's aim was to deepen understanding of factors that support high school attendance. A strengths-based participatory approach using photovoice addressed attendance factors as perceived by seven participating students from one high school in Finnmark. Qualitative content analysis of data generated through group dialogue about participant-generated photos and individual interviews identified six factors important for students' school attendance: a supportive school environment, a good learning environment, recuperation and recreation, family and friends, goals and ambitions, and place attachment. Related aspects of a supportive environment and belongingness, where school staff made important contributions to promoting a positive environment, were essential.

Chemistry and the Environment This issue contains more than 20 articles relating to the environment. Several articles of potential interest are indicated in the Table of Contents with the SSC mark (). Others are not so indicated because they depict use of expensive instrumentation or costly procedures, but if you have an interest in environmental chemistry you may wish to examine all the environmentally related articles. While many of the articles, both marked and unmarked, are targeted to college-level environmental chemistry curricula or to introductory courses for non-major, the methods described in several could be readily adapted to high school chemistry courses. One article likely to be of interest to teachers is found in News from Online, pp 1608-1609. The author explains how to use the U.S. Environment Protection Agency's EnviroMapper Web site to view and query environmental information. She mentioned finding a hazardous waste handler located near her home, so I decided to check the area near my home. I quickly located a natural gas salt dome storage facility marked on the map and, with a few more mouse clicks, I found information that included status of compliance with regulations, amounts of each compound released to the air in tons per year, and how to contact the corporation owning the site. Email and Web site addresses were included for the convenience of anyone wishing to contact the corporation. Students could learn a great deal about where they live that is relevant to chemistry by using the EPA site. Additional Web sites dealing with environmental issues and chemistry are cited in the sidebar at the bottom of p 1609. Among the articles that could be adapted to an advanced high school chemistry class or possibly even to an introductory class is one titled Bridge of Mandolin County (pp 1671-1672). It describes a case-study strategy similar to the scenarios used in ChemStudy. Students analyze information from various sources, including laboratory

Although eye injuries constitute a small percentage of high school and college sports injuries, they have the potential to be permanently debilitating. Eye injury rates will vary by sport, sex, and between the high school and college age groups. Descriptive epidemiology study. Level 3. Data from eye injury reports in high school and college athletes were obtained from the National High School Sports-Related Injury Surveillance System, High School Reporting Information Online (HS RIO) database over a 10-year span (2005-2006 through 2014-2015 school years) and the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) over an 11-year span (2004-2005 through 2014-2015 school years). Injury rates per 100,000 athlete-exposures (AEs), injury rate ratios (RRs), and 95% CIs were calculated. Distributions of eye injuries by diagnosis, mechanism, time loss, and surgery needs were also examined. A total of 237 and 273 eye injuries were reported in the HS RIO and the NCAA ISP databases, respectively. The sports with the highest eye injury rates (per 100,000 AEs) for combined high school and college athletes were women's basketball (2.36), women's field hockey (2.35), men's basketball (2.31), and men's wrestling (2.07). Overall eye injury rates at the high school and college levels were 0.68 and 1.84 per 100,000 AEs, respectively. Eye injury rates were higher in competition than practice in high school (RR, 3.47; 95% CI, 2.69-4.48) and college (RR, 3.13; 95% CI, 2.45-3.99). Most injuries were contusions (high school, 35.9%; college, 33.3%) and due to contact (high school, 89.9%; college, 86.4%). Only a small percentage of injuries resulted in time loss over 21 days (high school, 4.2%; college, 3.0%). Eye injury rates and patterns vary by sport, sex, and between the high school and college age groups. Although severe injuries do occur, most eye injuries sustained by high school and college athletes are minor, with limited time loss and full recovery

Correlation Among Students’ Family Background, Academic Performance in Junior High School, and Senior High School Tracking in Taiwan

Directory of Open Access Journals (Sweden)

Full Text Available There were numerous previous studies on educational tracking. However, most of the data adopted in these studies were collected a decade ago, involving sample population 20-64 years of age. Among them, many elderly samples had undergone senior high school tracking in the early years. The present study used the data of students and parents from the 3rd wave (2005 of the Taiwan Education Panel Survey (TEPS. A path analysis was conducted to investigate the inequality of opportunities involved in the influence of student family background on educational tracking at the senior high school stage. The results show: although the overall percentage of junior high school graduates entering advanced levels was approximately 100% and almost all students of different family backgrounds entered advanced levels, the most crucial factor among those affecting educational tracking of senior high school stage was students’ academic performance during junior high school. Students with higher family socioeconomic status and fewer siblings showed better academic performance in junior high schools, and consequently had higher possibilities of entering public senior high schools leading to a more promising future. This indicates that though the inequality in the quantity of opportunities approached 0, the inequality in the quality of opportunities still remained, which fails to support the hypothesis of the maximally maintained inequality of educational opportunity (MMI; however, the result supports the hypothesis of the effectively maintained inequality of educational opportunity (EMI.

The Surgeon General has called for an expansion of school-based extracurricular sports programs to address the obesity epidemic. However, little is known about the availability of and participation in high school extracurricular sports and how participation in these sports is related to high-risk behaviors. We surveyed Los Angeles County public high schools in 2002 to determine the number of extracurricular sports programs offered and the percentage of students participating in those programs. We used community data on rates of arrests, births, and sexually transmitted diseases (STDs) among youth to examine associations between risk behaviors and participation in sports programs. The average school offered 14 sports programs, and the average participation rate was 39% for boys and 30% for girls. Smaller schools and schools with higher percentages of disadvantaged students offered fewer programs. The average school offering 13 or fewer programs had 14% of its students participating, while the average school offering 16 or more programs had 31% of its students participating in sports. Controlling for area-level demographics, juvenile arrest rates and teen birth rates, but not STD rates, were lower in areas where schools offered more extracurricular sports. Opportunities for participation in high school extracurricular sports are limited. Future studies should test whether increased opportunities will increase physical activity and impact the increasing overweight problem in youths.

Should School Boards Discontinue Support for High School Football?

A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from sports injuries. In this paper, 3 experts also review the evidence about sports risks and discuss what is known and not known about the science and the ethics of high school football.

We identified the most effective mix of school-based policies, programs, and regional environments associated with low school smoking rates in a cohort of Canadian high schools over time. We collected a comprehensive set of student, school, and community data from a national cohort of 51 high schools in 2004 and 2007. Hierarchical linear modeling was used to predict school and community characteristics associated with school smoking prevalence. Between 2004 and 2007, smoking prevalence decreased from 13.3% to 10.7% in cohort schools. Predictors of lower school smoking prevalence included both school characteristics related to prevention programming and community characteristics, including higher cigarette prices, a greater proportion of immigrants, higher education levels, and lower median household income. Effective approaches to reduce adolescent smoking will require interventions that focus on multiple factors. In particular, prevention programming and high pricing for cigarettes sold near schools may contribute to lower school smoking rates, and these factors are amenable to change. A sustained focus on smoking prevention is needed to maintain low levels of adolescent smoking.

The purpose of the study was to identify structures and systems implemented in a high-performing high-poverty urban school to promote high academic achievement among students of color. The researcher used a sociocultural theoretical framework to examine the influence of culture on the structures and systems that increased performance by African American and Hispanic students. Four research questions guided the study: (1) What are the trends and patterns of student performance among students of color? (2) What are the organizational structures and systems that are perceived to contribute to high student performance in high-poverty urban schools with high concentrations of students of color? (3) How are the organizational structures and systems implemented to support school-wide effective classroom instruction that promotes student learning? (4) How is the construct of race reflected in the school's structures and systems? Qualitative data were collected through interviews, observations, and artifact collection. A single case study method was employed and collected data were triangulated to capture and explore the rich details of the study. The study focused on a high-performing high-poverty urban elementary school located in southern California. The school population consisted of 99% students of color and 93% were economically disadvantaged. The school was selected for making significant and consistent growth in Academic Performance Index and Adequate Yearly Progress over a 3-year period. The school-wide structures and systems studied were (a) leadership, (b) school climate and culture, (c) standards-based instruction, (d) data-driven decision making, and (e) professional development. Four common themes emerged from the findings: (a) instructional leadership that focused on teaching and learning; (b) high expectations for all students; (c) school-wide focus on student achievement using standards, data, and culturally responsive teaching; and (d) positive

Soil and minespoil fill as media for renovation of nitrogen and phosphorus in domestic wastewater

1998-01-01

Development of US Appalachian coal mining regions has been hampered by lack of domestic waste disposal technologies suited to fills. The suitability of on-site wastewater treatment and disposal systems (OSWTDS) in fill material is uncertain due to the effects of surface mining on soil physical properties. This research evaluated the potential for renovation of N and P present in domestic wastewater by fills from mining operations. N and P were chosen because of their potential adverse environmental impacts. Soil-fill (a mixture of Jefferson, fine-loamy, siliceous, mesic Typic Hapludult and Muskingom, fine-loamy, mixed, mesic Typic Dystrochrept soils) and minespoil (spoil)-fill (blasted rock material associated with the Taggart Marker and Low Splint Bench coal seams of the Upper Middle Wise Formation) were used. Septic tank effluent (STE) and sand filter effluent (SFE) were applied to spoil-fill columns at four loading rates and spoil-fill columns at one loading rate for a period of 20 wk. Renovation of wastewater was assessed by determining the concentration of N and P present in column leachate. Reduction of inorganic N(NO 3 - + NH 4 + ), based on N/Cl ratios ranged from 14.9 to 32.1% after the varying application rates of STE and SFE passed through the soil columns. However, leachate NO 3 - -N concentrations were still above the 10 mg -1 drinking water standard. The quantity of P emerging from the spoil-fill columns (3.0 mg PL -1 ) was higher than anticipated and may be related to the indigenous P present in the minespoil. Sorption of P in the spoil-fill column decreased with increased STE and SFE application (reduction ranged from 99.1 to 74.4%). Results from this study indicate that there is potential for renovating wastewater in OSWTDS in selected soil-fill areas in reclaimed minelands. 33 refs., 2 figs., 4 tabs

High school science fair and research integrity

Research misconduct has become an important matter of concern in the scientific community. The extent to which such behavior occurs early in science education has received little attention. In the current study, using the web-based data collection program REDCap, we obtained responses to an anonymous and voluntary survey about science fair from 65 high school students who recently competed in the Dallas Regional Science and Engineering Fair and from 237 STEM-track, post-high school students (undergraduates, 1st year medical students, and 1st year biomedical graduate students) doing research at UT Southwestern Medical Center. Of the post-high school students, 24% had competed in science fair during their high school education. Science fair experience was similar overall for the local cohort of Dallas regional students and the more diverse state/national cohort of post-high school students. Only one student out of 122 reported research misconduct, in his case making up the data. Unexpectedly, post-high school students who did not participate in science fair anticipated that carrying out science fair would be much more difficult than actually was the case, and 22% of the post-high school students anticipated that science fair participants would resort to research misconduct to overcome obstacles. No gender-based differences between students’ science fair experiences or expectations were evident. PMID:28328976

Yang, Junhua; Li, Yong; Cheng, Wei; Liu, Yang; Liu, Chenxi

2018-01-22

Received Signal Strength Indicator (RSSI) localization using fingerprint has become a prevailing approach for indoor localization. However, the fingerprint-collecting work is repetitive and time-consuming. After the original fingerprint radio map is built, it is laborious to upgrade the radio map. In this paper, we describe a Fingerprint Renovation System (FRS) based on crowdsourcing, which avoids the use of manual labour to obtain the up-to-date fingerprint status. Extended Kalman Filter (EKF) and Gaussian Process Regression (GPR) in FRS are combined to calculate the current state based on the original fingerprinting radio map. In this system, a method of subset acquisition also makes an immediate impression to reduce the huge computation caused by too many reference points (RPs). Meanwhile, adjusted cosine similarity (ACS) is employed in the online phase to solve the issue of outliers produced by cosine similarity. Both experiments and analytical simulation in a real Wireless Fidelity (Wi-Fi) environment indicate the usefulness of our system to significant performance improvements. The results show that FRS improves the accuracy by 19.6% in the surveyed area compared to the radio map un-renovated. Moreover, the proposed subset algorithm can bring less computation.

Full Text Available The architecture offices Atelier de la Seine and Rethink have been commissioned with the engineers Pouget Consultants by the social landlord Paris Habitat for the extensive renovation of a social housing estate in the historic centre of Paris. The estate has been built in 1930 and integrates a part of the former college of the Lombard build in the 17th century. It belongs to the social housing typology 'Habitations à Bon Marché (HBM' constructed between1894 and 1949. This typology is generally characterized by its integration in its urban context and an apparent brick facade. The renovation project includes a focus on the reduction of the energy consumption. An important subject, as of the total number of 4.6 millions of social housing in France more than 50 % have been build before 1975 (before the first thermal regulation and many are still considered energy-intensive.

Dual Campus High School

Full Text Available September 2010 witnessed the opening of the first complete dual campus high school in Alberta. Catholic Central High School, which had been in existence since 1967 in one building, now offered courses to students on two campuses. The “dual campus” philosophy was adopted so as to ensure maximum program flexibility for students. The philosophy, however, was destined to affect student engagement and staff efficacy as the change in organizational structure, campus locations, and course availability was dramatic. Changing school organizational structure also had the potential of affecting student achievement. A mixed-methods study utilizing engagement surveys, efficacy scales, and interviews with students and teachers was used to ascertain the degree of impact. The results of the study showed that minimal impact occurred to levels of student engagement, minor negative impact to staff efficacy, and a slight increase to student achievement results.

2013-01-01

The National Standards for High School Psychology Curricula attempts to represent current knowledge in the field of psychology in developmentally appropriate ways. Psychology is a popular high school course, one that can introduce students to scientific ideas and engage students in the learning process. However, it is difficult for even the best of teachers to present all of psychology in a single course for students who begin with virtually no formal knowledge of psychology. The standards presented here constitute the first of two reports in this issue of the American Psychologist (January 2013) representing recent American Psychological Association (APA) policies that support high-quality instruction in the teaching of high school psychology. These standards provide curricular benchmarks for student learning in the high school course.

To investigate the presence of cyberbullying among Greek students and the efficacy of proposed preventive interventions. Three types of high schools (private, experimental and public) with different politics on on-line aggression were enrolled. All students of the aforementioned schools were asked to complete an anonymous questionnaire. Around 62 % of the high school students experienced cyberbullying by electronic means, especially by cell phone, mostly the public school students (p 0.008). The bully was a stranger in more than 40 % of the cases. Over 60 % of the victims had not seeked help but dealt with the attack on their own. Only 20 % of the victims manifested sleep or eating disorders, physical/ psychological symptoms or changes in their social life as a consequence of the cyber-attack. Cyberbullying is a usual phenomenon among high school students. The bully is frequently unacquainted to the victim. Most of the victims are not physically or psychologically affected by the cyber-attack and do not share the event with anyone. There was a slight difference in the response of the students to cyberbullying among the different school politics of on-line aggression.

Sports-related injuries among high school athletes--United States, 2005-06 school year.

Science.gov (United States)

2006-09-29

Participation in high school sports helps promote a physically active lifestyle. High school sports participation has grown from an estimated 4 million participants during the 1971-72 school year to an estimated 7.2 million in 2005-06. However, despite the documented health benefits of increased physical activity (e.g., weight management, improved self-esteem, and increased strength, endurance, and flexibility), those who participate in athletics are at risk for sports-related injuries. High school athletes account for an estimated 2 million injuries, 500,000 doctor visits, and 30,000 hospitalizations annually. To date, the study of these injuries has been limited by inabilities to calculate injury rates, compare results among groups, and generalize findings from small, nonrepresentative samples. During the 2005-06 school year, researchers at a children's hospital in Ohio used an Internet-based data-collection tool to pilot an injury surveillance system among athletes from a representative national sample of U.S. high schools. This report summarizes the findings of that study, which indicated that participation in high school sports resulted in an estimated 1.4 million injuries at a rate of 2.4 injuries per 1,000 athlete exposures (i.e., practices or competitions). Surveillance of exposure-based injury rates in a nationally representative sample of high school athletes and analysis of injury patterns can help guide activities aimed at reducing these injuries.

Insufficient sleep among children and adolescents is associated with increased risk for obesity, diabetes, injuries, poor mental health, attention and behavior problems, and poor academic performance (1-4). The American Academy of Sleep Medicine has recommended that, for optimal health, children aged 6-12 years should regularly sleep 9-12 hours per 24 hours and teens aged 13-18 years should sleep 8-10 hours per 24 hours (1). CDC analyzed data from the 2015 national, state, and large urban school district Youth Risk Behavior Surveys (YRBSs) to determine the prevalence of short sleep duration (school nights among middle school and high school students in the United States. In nine states that conducted the middle school YRBS and included a question about sleep duration in their questionnaire, the prevalence of short sleep duration among middle school students was 57.8%, with state-level estimates ranging from 50.2% (New Mexico) to 64.7% (Kentucky). The prevalence of short sleep duration among high school students in the national YRBS was 72.7%. State-level estimates of short sleep duration for the 30 states that conducted the high school YRBS and included a question about sleep duration in their questionnaire ranged from 61.8% (South Dakota) to 82.5% (West Virginia). The large percentage of middle school and high school students who do not get enough sleep on school nights suggests a need for promoting sleep health in schools and at home and delaying school start times to permit students adequate time for sleep.

Care to Share? An Informal Syllabus Exchange A recent email message from Thomas Shiland, who teaches at Saratoga Springs Senior High School, noted that the process of revising the high school chemistry syllabus is underway in New York State. He expressed a strong interest in helping construct a chemistry syllabus that represents the best thinking about appropriate content. He wondered if it would be possible to develop a way in which different secondary chemistry syllabi could easily be exchanged. It is likely that readers from other states and countries are involved in a similar process and might also be interested in exchanging syllabi. Many states do not use the term syllabus to describe their guiding curricular document for chemistry but rather refer to it as a framework or as guidelines. In most cases, the document includes a list of key ideas or topics, performance indicators, and the major understandings associated with each key idea. Such documents would be appropriate for exchange among those of you involved in the revision process. If you are interested in arranging an exchange please contact me by email at j.e.howell@usm.edu or by mail at J. E. Howell, Box 5043, USM, Hattiesburg, MS39406-5043, USA.

Guide to Operating and Maintaining EnergySmart Schools

Energy Technology Data Exchange (ETDEWEB)

None

2010-01-01

Through a commitment to high performance, school districts are discovering that smart energy choices can create lasting benefits for students, communities, and the environment. For example, an energy efficient school district with 4,000 students can save as much as $160,000 a year in energy costs. Over 10 years, those savings can reach $1.6 million, translating into the ability to hire more teachers, purchase more textbooks and computers, or invest in additional high performance facilities. Beyond these bottomline benefits, schools can better foster student health, decrease absenteeism, and serve as centers of community life. The U.S. Department of Energy's EnergySmart Schools Program promotes a 30 percent improvement in existing school energy use. It also encourages the building of new schools that exceed code (ASHRAE 90.11999) by 50 percent or more. The program provides resources like this Guide to Operating and Maintaining EnergySmart Schools to assist school decisionmakers in planning, financing, operating, and maintaining energy efficient, high performance schools. It also offers education and training for building industry professionals. Operations and maintenance refer to all scheduled and unscheduled actions for preventing equipment failure or decline with the goal of increasing efficiency, reliability, and safety. A preventative maintenance program is the organized and planned performance of maintenance activities in order to prevent system or production problems or failures from occurring. In contrast, deferred maintenance or reactive maintenance (also called diagnostic or corrective maintenance) is conducted to address an existing problem. This guide is a primary resource for developing and implementing a districtor schoolwide operations and maintenance (O&M) program that focuses on energy efficiency. The EnergySmart Schools Solutions companion CD contains additional supporting information for design, renovation, and retrofit projects. The objective

Transitions from high school to college.

Science.gov (United States)

Venezia, Andrea; Jaeger, Laura

2013-01-01

The vast majority of high school students aspire to some kind of postsecondary education, yet far too many of them enter college without the basic content knowledge, skills, or habits of mind they need to succeed. Andrea Venezia and Laura Jaeger look at the state of college readiness among high school students, the effectiveness of programs in place to help them transition to college, and efforts to improve those transitions. Students are unprepared for postsecondary coursework for many reasons, the authors write, including differences between what high schools teach and what colleges expect, as well as large disparities between the instruction offered by high schools with high concentrations of students in poverty and that offered by high schools with more advantaged students. The authors also note the importance of noncurricular variables, such as peer influences, parental expectations, and conditions that encourage academic study. Interventions to improve college readiness offer a variety of services, from academic preparation and information about college and financial aid, to psychosocial and behavioral supports, to the development of habits of mind including organizational skills, anticipation, persistence, and resiliency. The authors also discuss more systemic programs, such as Middle College High Schools, and review efforts to allow high school students to take college classes (known as dual enrollment). Evaluations of the effectiveness of these efforts are limited, but the authors report that studies of precollege support programs generally show small impacts, while the more systemic programs show mixed results. Dual-enrollment programs show promise, but the evaluation designs may overstate the results. The Common Core State Standards, a voluntary set of goals and expectations in English and math adopted by most states, offer the potential to improve college and career readiness, the authors write. But that potential will be realized, they add, only if the

A longitudinal study of school belonging and academic motivation across high school.

2013-01-01

This longitudinal study examined how school belonging changes over the years of high school, and how it is associated with academic achievement and motivation. Students from Latin American, Asian, and European backgrounds participated (N = 572; age span = 13.94-19.15 years). In ninth grade, girls' school belonging was higher than boys'. Over the course of high school, however, girls' school belonging declined, whereas boys' remained stable. Within-person longitudinal analyses indicated that years in which students had higher school belonging were also years in which they felt that school was more enjoyable and more useful, above and beyond their actual level of achievement. Results highlight the importance of belonging for maintaining students' academic engagement during the teenage years. © 2012 The Authors.

Dejan Pajk

2010-01-01

Full Text Available Enterprise resource planning (ERP systems are often used by companies to automate and enhance their busi- ness processes. The capabilities of ERP systems can be described by best-practice reference models. The purpose of the article is to demonstrate the business process renovation approach with the use of reference models. Although the use of reference models brings many positive effects for business, they are still rarely used in Slovenian small and medium-sized compa- nies. The reasons for this may be found in the reference models themselves as well as in project implementation methodologies. In the article a reference model based on Microsoft Dynamics NAV is suggested. The reference model is designed using upgraded BPMN notation with additional business objects, which help to describe the models in more detail.

Full Text Available Although several studies have recently assessed direct self-injurious behavior (D-SIB among adolescents, it is still understudied in adolescents attending vocational schools: an educational setting generally associated with lower socioeconomic status. After extending the “Saving and Empowering Young Lives in Europe” (SEYLE project to a vocational school population, we examined their D-SIB and life event characteristics compared to the high school population. SEYLE’s Hungarian randomly selected high school sample (N = 995 was completed with a randomly selected vocational school sample (N = 140 in Budapest, Hungary. Participants aged 14–17 years completed the SEYLE project’s self-administered questionnaires. D-SIB lifetime prevalence was significantly higher (29.4% in the vocational school group compared to the high school group (17.2% (Χ2(1 = 12.231, p< 0.001. D-SIB was associated with suicidal ideation in the vocational school group. Different life events were more frequent in the high school than in the vocational school group, and associations between D-SIB and life events differed in the vocational school group compared to the high school group. In conclusion, vocational school students are a vulnerable population with a higher prevalence of D-SIB compared to high school students. Life events and their association with D-SIB also differ in vocational school students compared to high school students. Taking all these into account might contribute to prevention/intervention designed for this population.

So that the construction stages, of operation, closing, dismantlement and the radioactive waste disposal of a nuclear power plant (NPP) are carried out in Mexico, is necessary that the operator has a license, permission or authorization for each stage. In Mexico, these licenses, permissions or authorizations are granted by the Energy Secretariat with base in the verdict of the Comision Nacional de Seguridad Nuclear y Salvaguardias (CNSNS). The operation licenses ar the moment effective for the reactors of the Nuclear Power Plant of Laguna Verde (NPP-L V) they will expire respectively in the year 2020 and 2025 for the Unit 1 and Unit 2, for what the CNSNS has begun its preparation before a potential solicitude of the licensee to continue the operation of the NPP-L V. Defining the process to continue and to generate the documents that would help in this phase as normalization, guides, procedures, regulations, controls, etc., is the task that intends to be carried out the regulator body so that the evaluation process is effective and efficient, so much for the same regulator body as for the licensee. This work exposes the advance that the CNSNS has in this aspect and is centered specifically in the conformation of an evaluation process of license renovation solicitude, taking as base what the regulator body of the United States of North America (US NRC) established and following to the IAEA. Also, this work includes statistical of electric power production in Mexico, licensing antecedents for the NPP-L V, a world perspective of the license renovations and the regulation of the US NRC related to the license renovation of a NPP.

2013-07-01

Aiming at serious slag on the water wall around the burner of corner-fired boiler with low-ash-fusion-point coal, cold experimental model has been established. In this experiment, particle image velocimetry (PIV) has been employed to accurately measure aerodynamic field of burner region, and the experimental research of furnace slag renovation has been conducted through changing the burner jet arrangement. The experiment results show that it has significantly effect on aerodynamic field in the furnace by changing burner jet deflection angle. A reasonable actual tangential circle diameter can be formed through adjusting the burner jet deflection angle, to prevent primary air attacking the wall, and further more, to effectively prevent serious slag on the water wall around the burner.

2017-04-15

Many young adults have utilized indoor ultraviolet(UV) tanning, putting them at higher risk for development of skin cancers. Prior to the increased regulations on indoor tanning for minors, indoor tanning businesses marketed to teens through modalities such as advertisements in high school newspapers. The purpose of this study was to quantify tanning advertisements in high school newspapers published across the United States between August 2014 and July 2015. Online versions of the newspaper issues were available on issuu.com. Tanning advertisements appeared in 3 of 23 high school newspapers with advertisements of any kind(13%). Among all newspapers with advertisements, 10% were indoor tanning advertisements. One newspaper in Colorado contained advertisements of any kind and had 0 tanning advertisements. A prior study of Colorado high schools showed 11 of 23 schools (48%) to contain tanning advertisements. This suggests that there may be a decrease in indoor UV tanning advertisements owing to increased tanning regulation by state legislatures, national attention to UV tanning, or a general decrease in high school tanning advertisements.

Effects of Perceived Discrimination on the School Satisfaction of Brazilian High School Graduates

Directory of Open Access Journals (Sweden)

Rubia R. Valente

2017-01-01

Full Text Available This paper analyzes the consequences of peer victimization for the satisfaction with schooling (“happiness” of college-bound high school graduates in Brazil.  Several types of victimization are explored including discrimination due to race/ethnicity, socioeconomic status, gender, sexual orientation, religious affiliation, and disability. We compare the satisfaction with their schooling of students planning to head to college straight from high school and older students applying for college later in life (“nontraditional students”. We conclude that students who perceived that they had been discriminated against were more dissatisfied with their school experience than those who did not, ceteris paribus, and we relate level of dissatisfaction to type of discrimination. The older student evidence reveals that this dissatisfaction wanes with time and age, however. Our conclusions are based upon ordered logistic analyses of data for 2.4 million current high school seniors and 78.7 thousand older students drawn from the Exame Nacional do Ensino Médio questionnaire (ENEM.

2016-12-01

This study aimed to examine the association between body mass index (BMI) and school performance in high school students by controlling for relevant mediators such as sleep quality, sleep duration and socioeconomic status. Thirty-seven high school students (mean age: 18.16 ± 0.44 years) attending the same school type, i.e. 'liceo scientifico' (science-based high school), were enrolled. Students' self-reported weight and height were used to calculate BMI. Participants wore an actigraph to objectively assess the quality and duration of sleep. School performance was assessed through the actual grade obtained at the final school-leaving exam, in which higher grades indicate higher performance. BMI, get-up time, mean motor activity, wake after sleep onset and number of awakenings were negatively correlated with the grade, while sleep efficiency was positively correlated. When performing a multiple regression analysis, BMI proved the only significant (negative) predictor of grade. When controlling for sleep quality, sleep duration and socioeconomic status, a higher BMI is associated with a poorer school performance in high school students. © 2015 World Obesity Federation.

McKean, p 916 * A pHorseshoe, by Roger Plumsky, p 935 National Conferences in Your Part of the Country For the past several months, considerable space in this column has been devoted to forthcoming national conferences and conventions and to highlights of conferences past. For some of us, location is fairly unimportant; but for most of us travel costs and time are both factors to consider when choosing a conference. The community of high school chemistry teachers is favored by the number of national conventions and conferences that are held each year in different locations. In 1999, for example, the spring National Meeting of the American Chemical Society was in Anaheim and the National Science Teachers Association National Convention was in Boston. This summer CHEMED '99 will be held in Fairfield, CT, August 1-5, and the fall National ACS Meeting will be in New Orleans. Teachers from the mid-South especially should consider attending the High School Program at New Orleans, described below by Lillie Tucker Akin, Chairperson of the Division's High School Program Committee. The event will be held on Sunday to minimize conflicts with the beginning of the school year.

Energy Efficiency and Universal Design in Home Renovations - A Comparative Review.

Science.gov (United States)

Kapedani, Ermal; Herssens, Jasmien; Verbeeck, Griet

2016-01-01

Policy and societal objectives indicate a large need for housing renovations that both accommodate lifelong living and significantly increase energy efficiency. However, these two areas of research are not yet examined in conjunction and this paper hypothesizes this as a missed opportunity to create better renovation concepts. The paper outlines a comparative review on research in Energy Efficiency and Universal Design in order to find the similarities and differences in both depth and breadth of knowledge. Scientific literature in the two fields reveals a disparate depth of knowledge in areas of theory, research approach, and degree of implementation in society. Universal Design and Energy Efficiency are part of a trajectory of expanding scope towards greater sustainability and, although social urgency has been a driver of the research intensity and approach in both fields, in energy efficiency there is an engineering, problem solving approach while Universal Design has a more sociological, user-focused one. These different approaches are reflected in the way home owners in Energy Efficiency research are viewed as consumers and decision makers whose drivers are studied, while Universal Design treats home owners as informants in the design process and studies their needs. There is an inherent difficulty in directly merging Universal Design and Energy Efficiency at a conceptual level because Energy Efficiency is understood as a set of measures, i.e. a product, while Universal Design is part of a (design) process. The conceptual difference is apparent in their implementation as well. Internationally energy efficiency in housing has been largely imposed through legislation, while legislation directly mandating Universal Design is either non-existent or it has an explicit focus on accessibility. However, Energy Efficiency and Universal Design can be complementary concepts and, even though it is more complex than expected, the combination offers possibilities to advance

Full Text Available Desde el inicio del proceso de reforma de la política energética de la Unión Europea, los paisajes emergentes a partir de generación de electricidad con energías renovables suscitan un interés creciente. España se caracteriza por una implantación muy exitosa de las políticas europeas en materia de energías renovables. Sin embargo, la proliferación de aerogeneradores y placas fotovoltaicas en espacios agrícolas o improductivos conlleva la destrucción de numerosos paisajes muy valiosos. Por lo que la nueva sensibilidad hacia los paisajes se está convirtiendo en el mayor obstáculo para el desarrollo de las energías renovables. El objetivo de este artículo es explorar en la relación que se establece entre la implantación de las energías renovables y la evolución de las políticas paisajísticas. Para ello, se analiza el desarrollo que han experimentado las políticas de energías renovables en Europa y en España; se estudian las nuevas formas democráticas de gestión del territorio que plantea la Convención Europea del Paisaje. Por último, se tratan determinados temas de la inclusión del paisaje en las políticas de energías renovables en España, comentando algunos ejemplos en los que se detectan nuevas estrategias en la implantación de proyectos de energías renovables que pueden reducir los impactos sobre el paisaje.

Study Objectives: Several organizations have provided recommendations to ensure high school starts no sooner than 08:30. However, although there are plausible biological reasons to support such recommendations, published recommendations have been based largely on expert opinion and a few observational studies. We sought to perform a critical review of published evidence regarding the effect of high school start times on sleep and other relevant outcomes. Methods: We performed a broad literature search to identify 287 candidate publications for inclusion in our review, which focused on studies offering direct comparison of sleep time, academic or physical performance, behavioral health measures, or motor vehicular accidents in high school students. Where possible, outcomes were combined for meta-analysis. Results: After application of study criteria, only 18 studies were suitable for review. Eight studies were amenable to meta-analysis for some outcomes. We found that later school start times, particularly when compared with start times more than 60 min earlier, are associated with longer weekday sleep durations, lower weekday-weekend sleep duration differences, reduced vehicular accident rates, and reduced subjective daytime sleepiness. Improvement in academic performance and behavioral issues is less established. Conclusions: The literature regarding effect of school start time delays on important aspects of high school life suggests some salutary effects, but often the evidence is indirect, imprecise, or derived from cohorts of convenience, making the overall quality of evidence weak or very weak. This review highlights a need for higher-quality data upon which to base important and complex public health decisions. Citation: Morgenthaler TI, Hashmi S, Croft JB, Dort L, Heald JL, Mullington J.

Reports from the French Ministry of Education warn of a decrease in the use of school food services, especially in sensitive urban areas. They also suggest that this decline has led to cases of malnutrition. This article describes the characteristics of the current supply of school meals and measures the evolution of demand observed between 1992 and 1996 in relation to the economic situation of students' families. The study was carried out in 3 departments in France: Doubs, Herault, and Val de Marne. The administrators of all public and private middle and high schools in the 3 departments received a questionnaire asking them to describe the services offered in their cafeterias and to provide the corresponding statistical and accounting data. External food services near the schools were also taken into account. Seventy-nine percent of schools responded to the survey. Concerning the services offered, 91% of schools have their own cafeterias, of which 81% are managed by the schools. Concerning the evolution of utilisation, a significant decrease in the number of meals served in seen in middle schools. On the other hand, high schools have observed stable utilisation. The positive changes in utilisation are linked, in middle schools, to characteristics of the schools' internal food services (self-service, choice of main courses, modulation of seats). In high schools, positive changes in the utilisation of school services are linked to the lack of external food services near the schools. As middle schools and high schools control the logistics and management of food services offered to students, they are potentially in a position to influence a policy on this issue. The evolution in utilisation is very different among departments and between middle and high schools. While economic precariousness has a negative structural effect on utilisation, it doesn't seem to be a major factor in the evolution of the decrease observed over the past few years.

Carroquino Javier

2017-01-01

Full Text Available La energía utilizada en agricultura es fuente de emisiones de gases de efecto invernadero. Para reducir las producidas por el uso de gasóleo y electricidad, el proyecto europeo LIFE REWIND aborda el suministro desde fuentes renovables. Para ello, se ha caracterizado la demanda energética y recursos renovables en viñedo y bodega. Se ha buscado el diseño óptimo económico y medioambiental de la generación. Se ha instalado un prototipo en una explotación vitivinícola, con generación fotovoltaica, incluyendo un conjunto flotante sobre una balsa. Esto evita el uso de terreno, reduce la pérdida de agua de la balsa y mejora el rendimiento de los paneles fotovoltaicos. La electricidad producida alimenta la depuración de agua y el bombeo de riego por goteo del viñedo. Con la energía sobrante, un electrolizador produce hidrógeno mediante electrólisis del agua, que es utilizado por un vehículo todoterreno con pila de combustible. Los resultados muestran la viabilidad técnica y económica de los sistemas autónomos de energía renovable para alimentar el riego estacional en los viñedos. Así se evitan las extensiones indiscriminadas de la red y los grupos electrógenos diésel. Adicionalmente se muestra la posibilidad de reemplazar el gasóleo por electricidad o hidrógeno producido en la propia explotación.

[The influencing factors on alienation in high school students].

Science.gov (United States)

Lee, Eun-Sook

2004-02-01

This study was performed to identify the influencing factors on alienation among high school students. Data was collected by questionnaires from 550 students of academic and vocational high schools in G city. The data was analyzed using descriptive statistics, pearson correlation coefficients, and stepwise multiple regression. The scores of alienation among students in financially lower middle class and lower class were higher than those of the upper middle class students, resulting in significant differences(F=6.87, p=.00). A sense of alienation showed a significantly negative correlation with the scores of responding parenting style(r=-.32), family cohesion(r=-.33), school attachment(r=-.51), academic performance(r=-.34), peer relationships(r=-.38), self-control (r=-.43), and social skills(r=-.33). The most powerful predictor of alienation among high school students was school attachment and the variance explained was 26%. A combination of school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance account for 40% of the variance in alienation among high school students. This study suggests that school attachment, self control, peer relationships, family cohesion, demanding parenting style, and academic performance are significant influencing factors on alienation in high school students. Therefore, nursing strategy is needed to manage these revealed factors.

The interactive impacts of high school gay-straight alliances (GSAs) on college student attitudes toward LGBT individuals: an investigation of high school characteristics.

Science.gov (United States)

Worthen, Meredith G F

2014-01-01

Although gay-straight alliances (GSAs) are becoming more popular in high schools across the U.S., empirical studies investigating GSAs and their impact are sparse. Utilizing a sample of college students drawn from a large Southern university (N = 805; 78% White; 61% female; average age 22), the current study investigates the ways that the presence of high school GSAs affect college student attitudes toward LGBT individuals and how these relationships may vary by high school GSA location (South vs. non-South), town type (rural/small town, suburban, large city), and high school student population size. Overall, results from the current study show that the presence of a GSA in high school is a robust positive predictor of supportive attitudes toward LGBT individuals, even when considering many control variables. Such results suggest that the presence of GSAs in high schools may have significant positive and potentially long-lasting effects on college students' attitudes toward LGBT individuals.

Nižetić, S.

2018-02-01

This paper elaborates design scenarios for a sports complex in Croatia from a technical and economic aspect. Different energy options are analysed and two are additionally addressed and discussed as the most viable ones. The possibilities of sports complex renovation are shown by properly choosing the appropriate energy concept and thus reducing the overall cost for produced thermal energy by around 33% and reducing the carbon dioxide emission by a factor of 1.8 in comparison with its present state. Finally, this study presents an example of good practice, where renewable energy solutions can be proposed and where it is possible to cover around 70-80% of overall yearly costs from achieved energy savings for the novel plant that is assumed to be financed through a bank loan.

The design of nuclear power plants on anti-flood performance was only based on design basis condition in China. The Fukushima nuclear accident revealed the possibility of suffering flood under beyond design basis condition, which caused the continuously deterioration of Fukushima nuclear accident. After the accident, China national nuclear safety regulators proposed new requirements on performance of anti-flood of nuclear power plants. Then, Qinshan Phase II carried out research of anti-flood technology. This paper introduced the background, research and development of anti-flood renovation technology for important safety buildings of Qinshan Phase II, and discussed the necessary for improvement of anti-flood capacity of nuclear power plants and relative measures in China, which is helpful to improve anti-flood performance of operational nuclear power plants and nuclear power plants under construction.
