    Full Text Available The composition of the residential real estate and the structure of Russian housing market do not match: primary and secondary markets are supplemented by a considerable in size non-market sector of residential real estate - the stock of dilapidated housing and buildings in a state of emergency that is filling up the secondary market with rapidly growing volume of worn out properties. While the developmental model of entrepreneurship is gradually settling in the primary housing market, and in general the “soviet” model of management (management companies are not that different from the soviet property management agencies is remaining in the secondary market, the non-market sector requires a formulation of an adequate management model that would allow the private and public management of residential real estate at the same time. Mega-project of renovation of the 5-storey buildings in Moscow will support the formation of such a model and the legal grounds for its existence.

    Full Text Available Since the year 2000, during the period of economic growth, the real estate market has been rapidly expanding. During this period advertising of real estate objects was implemented using one set of similar channels (press advertising, Internet advertising, leaflets with contact information of real estate agents and others, however the start of the economic recession has intensified the competition in the market and forced companies to search for new advertising means or to diversify the advertising package. The article presents real estate property, as a product, one of the marketing components – including advertising, conclusions and suggestions based on conducted surveys and a model for advertising the residential real estate objects.Article in Lithuanian

  11. The Analysis of Differences in Residential Property Price Indices

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Residential property price indices can serve as a useful tool in the practice of real property market analysts, investment advisers, property developers, certified property appraisers, estate agents and managers. They can also be applied in property price valorization in specific legal positions. The Polish Act on Real Estate Management puts an obligation on the President of the Central Statistical Office to announce real property price indices, but the CSO fails to fulfill this obligation. The author’s rationale for this article is to contribute to works on rules of how to build property price indices. Presented within are the results of research on determining the price indices of such types of residential property as: a part of a building constituting a separate property and strata titles in housing cooperatives. The flats were divided into categories by floor area and by their location in 16 voivodeship capitals. The major purpose of the study is to prove that the prices of flats of different floor area change at different rates. Consequently, it seems worth considering whether a more detailed segmentation of the real estate market would be worthwhile for the sake of more accurate real property price indicators.

    2017-12-01

    Full Text Available Purchase and consumption behavioral patterns of various family formations in different social and cultural contexts have been subject to intensive investigation over the recent years. Residential real estate as a product category represents one of the most complex household purchases incorporating a wide diversity of attributes to be considered in order to match family members’ needs within available resources. The purpose of this paper is to add some insights into spousal perceptions of gender role specialization throughout a residential real estate purchase family decision-making process. The distribution of influence between husbands and wives across three decision-making stages, three sub-decisions and twelve housing attribute choices and the relative importance of twelve residential real estate characteristics are examined using a convenience sample of both spouses in 127 Bulgarian heterosexual married and cohabiting couples.

    2007-01-01

    Earlier research has found that specialization by real estate agents creates economies of scope for real estate firms. So far, however, no research has addressed this issue at the agent level. The question this research seeks to answer is whether specialization in one side of the real estate transaction increases agent income. The most important finding is that specialization has an asymmetric impact on earnings. Specializing in listings positively enhances agent income. In contrast, speciali...

  14. The Availability of Residential Real Estate Increasing by Means of State Compensation of Prices

    2015-12-01

    Full Text Available The article analyzes the influence of natural monopolies on the value of residential property, discusses the basic energy resources affecting it. Oil is defined as the main energy resource, its main brands, and their features are considered. The different authors’ perspectives of the impact of oil prices on the real estate prices are considered (“no effect”, “direct effect” and “indirect effect”. Schemes (models, clearly demonstrating the cause-and-effect relations of the impact of prices of the main energy resources on each other and on the value of residential property, are provided. The stability of relations between the prices of the major energy recourses (between each other as well as between each resource and real estate prices and residential property prices in the primary market are analyzed. The interval of “crisis” and “crisis-free” time is defined. The impact of the energy in “crisis” and “crisis-free” time is analyzed. The impact of oil prices on the residential property prices is proved through the cement as the main price-determining element in the construction. The introduction of the state target compensation allowing to increase the availability of residential property is proposed as one of the elements of a comprehensive solution of the “housing question”. The size of the state target compensation in absolute (in rubles and relative (% prices for residential real estate values is determined, taking into account the sufficient reproduction of the population, and restrictions on the right to use it are introduced. The total value of the state target compensation per total number of homebuyers is calculated, and its share in the expenditures of the consolidated budget and budgets of state extra-budgetary funds is determined. The realization of the state target compensation based on an average annual growth among the major countries of the world is grounded.

  20. Frequency Based Real-time Pricing for Residential Prosumers

    Science.gov (United States)

    Hambridge, Sarah Mabel

    This work is the first to explore frequency based pricing for secondary frequency control as a price-reactive control mechanism for residential prosumers. A frequency based real-time electricity rate is designed as an autonomous market control mechanism for residential prosumers to provide frequency support as an ancillary service. In addition, prosumers are empowered to participate in dynamic energy transactions, therefore integrating Distributed Energy Resources (DERs), and increasing distributed energy storage onto the distributed grid. As the grid transitions towards DERs, a new market based control system will take the place of the legacy distributed system and possibly the legacy bulk power system. DERs provide many benefits such as energy independence, clean generation, efficiency, and reliability to prosumers during blackouts. However, the variable nature of renewable energy and current lack of installed energy storage on the grid will create imbalances in supply and demand as uptake increases, affecting the grid frequency and system operation. Through a frequency-based electricity rate, prosumers will be encouraged to purchase energy storage systems (ESS) to offset their neighbor's distributed generation (DG) such as solar. Chapter 1 explains the deregulation of the power system and move towards Distributed System Operators (DSOs), as prosumers become owners of microgrids and energy cells connected to the distributed system. Dynamic pricing has been proposed as a benefit to prosumers, giving them the ability to make decisions in the energy market, while also providing a way to influence and control their behavior. Frequency based real-time pricing is a type of dynamic pricing which falls between price-reactive control and transactive control. Prosumer-to-prosumer transactions may take the place of prosumer-to-utility transactions, building The Energy Internet. Frequency based pricing could be a mechanism for determining prosumer prices and supporting

  1. Customer service in the residential property market of South Africa

    2004-07-01

    Full Text Available An increasing number of estate agencies are entering the real estate market in South Africa and many are struggling to survive as competition grows stronger. Customer service has become of overriding importance to establish a differential advantage that will ensure long-term survival. This study investigates customer service by estate agencies in the residential property market of South Africa. The results indicate that estate agencies seem to be aware of the importance of providing good customer service and of being service-oriented, but they do not always seem to realise the need to conduct marketing research and test the actual satisfaction of customers with the services provided, leaving a potential gap between what the customer wants and what the estate agency provides.

    Kolobova, Svetlana

    2018-03-01

    As you know, high-rise construction is an indicator of the practical implementation of advanced innovative technologies in the construction industry of the country. High-rise building inevitably comes to the big cities, in connection with the shortage and value of land. The life cycle of any construction project, including high-rise buildings consists of chains: of engineering survey - design-construction-operation. In the process of operation of a tall building, decisions about major repairs or reconstruction of a building are made for decision-making on further use. This article describes methods of assessing the consumer quality of high-rise residential buildings and the establishment of prices based on consumer characteristics of a tall residential building. It is proposed to assess the premises under their quality characteristics. The study was conducted to establish the influence of individual, comprehensive and integral indicators of comparable quality for effective quality living spaces. Simultaneously, there was established a relationship of quality with the consumer cost of housing, ultimately with the potential needs of owners, tenants of the home, lessor dwelling, or buyers of residential properties and other participants in the residential real estate market. This relationship further creates consumer requirements to quality standard of premises at a certain stage of socio-economic development.

  14. Guidelines for target costing adoption in the development of products for the residential real estate market

    Directory of Open Access Journals (Sweden)

    Reymard Savio Sampaio de Melo

    Full Text Available Abstract This study focuses on the problems associated with the traditional practice of reducing costs in construction and the need to increase business competitiveness in the residential real estate sector. In this context, target costing is a promising approach to improve the competitiveness of companies by ensuring that the products launched on the market do not jeopardize the company's results and value delivery to customers. However, far too little attention is paid to target costing implementation by companies that develop residential real state products for sale and face strong market competition. Thus, this paper seeks to investigate whether the standard framework of target costing in the literature applies - with or without adjustments - to real estate developers. Case study was the research strategy adopted. Guidelines are proposed for the introduction of target costing in the development process of residential real estate products. The proposed guidelines are related to the three main sections of the target costing process: market-driven costing, product-level target costing and component-level target costing.

  17. Effects of the accident at Three Mile Island on residential property values and sales. Final report, April 1980-January 1981

    International Nuclear Information System (INIS)

    Gamble, H.B.; Downing, R.H.

    1981-04-01

    The study examined the effects of the accident at Three Mile Island on residential property values and number of sales within a 25-mile radius of the plant. Regression analyses, using data on 583 actual market sales of single family homes from 1977 through 1979, examined the effects before and after the accident on the basis of distance and direction from the plant and on three different property value classes. All valid single family property sales between 1975 and 1979 within the 25-mile area were examined in a time series analysis. Interviews were conducted with realtors, financial institution officials and building contractors in the area. The accident had no measurable effects, positive or negative, on the value of single family residential properties within a 25-mile radius of the plant, or in any direction from the plant, or on low, medium, or high value properties. The plant had no measurable effects on residential property values for the 2 years prior to the accident. Immediately following the accident there was a sharp decline in the number of residential sales within 10 miles of the plant, but the real estate market returned to near normal conditions within 4-8 weeks. The interviews basically confirmed the above findings

  1. Are Housing Markets Decoupled? A Case Study of Residential Real Estate Affordability in Austria

    Directory of Open Access Journals (Sweden)

    Florian PHILIPP

    2015-09-01

    Full Text Available Real estate arguably forms the most important asset to most households and the basis for their wealth. Around this context a model has been set up testing the relative affordability of real estate for the median household in Austria and the consequences of lower borrowing costs between 2004 and 2013 by vintage year. In this paper the hypothesis that the significant decline in base interest rates is not sufficient to offset the relative affordability loss caused by declining net household incomes and the simultaneous increase of real estate prices. To test this hypothesis a model has been set up comparing two different Housing Affordability Indices – one including and one excluding financing effects, having been compared via a multi factor model. Based on this calculation the author finds decreased base interest rates to offset relative affordability losses by only approximately 50%, verifying the hypothesis. The paper therefore argues for a potential decoupling of the residential housing market in Austria.

  2. Residential Real Estate in Europe: An Exploration of Common Risk Factors

    Directory of Open Access Journals (Sweden)

    Druica Elena

    2015-12-01

    Full Text Available We conduct an exploratory analysis using proxy measures of cross-sectional returns and rental yields in residential real estate. Asset pricing models predict that expected returns should exhibit some sensitivity to one or several fundamental variables that represent a common source of undiversifiable risk. Residential real estate, just like works of art and collectibles, is unique because it represents both an investment vehicle and a durable consumption good. Its pricing and returns should thus reflect both the benefits from portfolio diversification and the effect of supply and demand. In this paper, we investigate the variation in proxy returns and proxy rental yields across 34 major European cities, using a handful of independent variables that should account for the influence of market risk, inflation, and liquidity. In spite of obvious limitations stemming from our sample, we find that the explanatory power of our model is unusually high for a cross-sectional data analysis. Some of our findings concur with other studies showing that in spite of strong segmentation, real estate markets respond to the same structural risk factors. A good portion of our results, however, is hard to explain and interpret. Either we need to take into account cultural differences between Eastern and Western Europe as part of a behavioral approach, or we have to concede that we have been misled by the mismatch in the level of aggregation and the crude estimation of the dependent variables.

    This study used several real-time and filter-based aerosol instruments to measure PM 2.5 levels in a high-rise residential green building in the Northeastern US and compared performance of those instruments. PM 2.5 24-hr average concentrations were determined using a Personal Modular Impactor (PMI) with 2.5 µm cut (SKC Inc., Eighty Four, PA) and a direct reading pDR-1500 (Thermo Scientific, Franklin, MA) as well as its filter. 1-hr average PM 2.5 concentrations were measured in the same apartments with an Aerotrak Optical Particle Counter (OPC) (model 8220, TSI, Inc., Shoreview, MN) and a DustTrak DRX mass monitor (model 8534, TSI, Inc., Shoreview, MN). OPC and DRX measurements were compared with concurrent 1-hr mass concentration from the pDR-1500. The pDR-1500 direct reading showed approximately 40% higher particle mass concentration compared to its own filter (n = 41), and 25% higher PM 2.5 mass concentration compared to the PMI 2.5 filter. The pDR-1500 direct reading and PMI 2.5 in non-smoking homes (self-reported) were not significantly different (n = 10, R 2 = 0.937), while the difference between measurements for smoking homes was 44% (n = 31, R 2 = 0.773). Both OPC and DRX data had substantial and significant systematic and proportional biases compared with pDR-1500 readings. However, these methods were highly correlated: R 2 = 0.936 for OPC versus pDR-1500 reading and R 2 = 0.863 for DRX versus pDR-1500 reading. The data suggest that accuracy of aerosol mass concentrations from direct-reading instruments in indoor environments depends on the instrument, and that correction factors can be used to reduce biases of these real-time monitors in residential green buildings with similar aerosol properties. This study used several real-time and filter-based aerosol instruments to measure PM 2.5 levels in a high-rise residential green building in the northeastern United States and compared performance of those instruments. The data show that while the use of real

    Full Text Available This study analyzed the impact of area residential property values, an objective measure of socioeconomic status (SES, on self-rated health (SRH in Seattle, Washington and Paris, France. This study brings forth a valuable comparison of SRH between cities that have contrasting urban forms, population compositions, residential segregation, food systems and transportation modes. The SOS (Seattle Obesity Study was based on a representative sample of 1394 adult residents of Seattle and King County in the United States. The RECORD Study (Residential Environment and Coronary Heart Disease was based on 7131 adult residents of Paris and its suburbs in France. Socio-demographics, SRH and body weights were obtained from telephone surveys (SOS and in-person interviews (RECORD. All home addresses were geocoded using ArcGIS 9.3.1 (ESRI, Redlands, CA. Residential property values were obtained from tax records (Seattle and from real estate sales (Paris. Binary logistic regression models were used to test the associations among demographic and SES variables and SRH. Higher area property values significantly associated with better SRH, adjusting for age, gender, individual education, incomes, and BMI. The associations were significant for both cities. A one-unit increase in body mass index (BMI was more detrimental to SRH in Seattle than in Paris. In both cities, higher area residential property values were related to a significantly lower obesity risk and better SRH. Ranked residential property values can be useful for health and weight studies, including those involving social inequalities and cross-country comparisons.

  13. The impact of oil and natural gas facilities on rural residential property values

    International Nuclear Information System (INIS)

    Boxall, P.C.

    2005-01-01

    This PowerPoint presentation examined challenges in the economic valuation of environmental changes within the context of formal real estate markets. It was proposed that some values that are expressed in markets can be affected by environmental changes and should be used in resource development land assessments. Details of indirect market valuation and revealed preference methods were reviewed. An outline of hedonic pricing was presented. It was noted that hedonic pricing can be used with other market values and prices such as tourism, art prices and hotel prices, where multivariate regression techniques are used and regression coefficients reveal information on the implicit prices of certain characteristics. Property value examples in the environmental economics literature were reviewed. A case study using data from eco-terrorism costs was presented. Issues concerning sour gas facilities were discussed with reference to public anxiety over hydrogen sulfide (H 2 S) toxicity and flares. Concerns over health risks and negative amenity impacts were discussed. The impacts of sour gas facilities on property values of residential acreages in and around Calgary were considered, and a map of the study area was presented. An outline of emergency plan response zones was provided. Price effects of industry facilities were presented, including marginal and cumulative impacts on price. It was concluded that oil and gas activities have significant impacts on rural residential property prices, but that industry members currently report that there is little to no effect. It was suggested that the research presented in this paper could be used to assess levels of compensation. tabs., figs

    Full Text Available The purpose of the article is to improve the system of mortgage crediting of residential real estate in Ukraine. Mortgage lending appeared in Ukraine in the early XVII century, today the actual problem is a small percentage of the banking book long-term mortgage loans, because banks, on the one hand, tend to rotate without the risk of short-term funds, another potential borrower of these loans, unfortunately, is not creditworthy. However, despite the risks, this banking product is a significant factor in the redistribution and accumulation of funds, the transformation of private savings into investment resources, the problem of housing, but also contributes to the stabilization of the economy in the country as a whole. Functioning and the distribution of mortgage capital, the possible financial risks, the interaction of the mortgage market by the financial, investment and monetary Affairs, leads to a certain complexity of the mechanism of functioning of the mortgage market of Ukraine in general. The relevance of this topic not only in the development of the housing market, but also the feasibility studies for the development of this issue. We present an analysis of the institutional environment of mortgage lending residential real estate, which gave an opportunity to identify and define the environment of modern residential real estate market, its relationship with other markets. Methodology. The survey is based on institutional structure of the mortgage market that has evolved independently of other structures, independently within country under the influence of specific socio-economic environment and economic policy. Results of the survey showed that mortgage lending can be providing the borrower with some free services, such as: long-term deposit on favorable terms, notary services, insurance, discounts on bank services, providing services to the bank and the developer, given appropriate training of the borrower and so forth.

  18. Application of the Beta Coefficient in the Market of Direct residential Real Estate Investments

    Directory of Open Access Journals (Sweden)

    Wolski Rafał

    2014-07-01

    Full Text Available The beta coefficient is one of the most popular indices used in contemporary finances. Despite the fact that there are justified doubts connected with its application, it is currently difficult to imagine a situation in which the cost of capital would be calculated without the use of the CAPM model. Thus, an attempt at answering the question whether and to what degree beta may be used in the real estate market constitutes an interesting problem. This is because on the one hand, the formal structure suggests that beta should not be used for assets which are not included in the benchmark but, on the other hand, such a benchmark should, at least theoretically, contain all market assets. Therefore, a decision was made to have a closer look at this issue, with the analysis of the possibility of using the beta coefficient in the residential real estate market set as the objective. Using the database of prices in the direct real estate investment created by the NBP, a comparison was conducted with regard to features of undertaken investments on the basis of an analysis of systematic risk calculated using selected indices available on the Polish market.

However, policy makers are still unsure as to the effect of commercial land uses such as shopping centres on surr...

  4. How Genetics Might Affect Real Property Rights: Currents in Contemporary Bioethics.

    Rothstein, Mark A; Rothstein, Laura

    2016-03-01

    New developments in genetics could affect a variety of real property rights. Mortgage lenders, mortgage insurers, real estate sellers, senior living centers, retirement communities, or other parties in residential real estate transactions begin requiring predictive genetic information as part of the application process. One likely use would be by retirement communities to learn an individual's genetic risk for Alzheimer's disease. The federal Fair Housing Act prohibits discrimination based on disability, but it is not clear that it would apply to genetic risk assessments. Only California law explicitly applies to this situation and there have been no reported cases. © 2016 American Society of Law, Medicine & Ethics.

  11. The Real estate market: types of property and criteria for appraisal

    Directory of Open Access Journals (Sweden)

    Mario Breglia

    2013-08-01

    Full Text Available The increasing interest on the part of institutional investors in the yield potential of real estate assets highlights the importance of effective criteria for evaluation. Each segment of real estate needs its own appraisal procedure, which is determined according to the intended use of the property: residential, tertiary/offices, special use property. Special use properties are characterised by their individual nature, their particular intended use. They include university buildings, hospitals and barracks. These are all segments which are impossible to assess using criteria based on comparable sales or income capitalisation. Institutional investors are now particularly interested in asset divestment by the State and public bodies. The low level of risk of this kind of investment is likely to be particularly attractive to institutional players and could represent a good opportunity to revive the real estate market.

  12. Value of Professional Property Managers in Residential Project Development

    Directory of Open Access Journals (Sweden)

    Yuen C. B.

    2016-06-01

    Full Text Available Property management has often been described as an after-sale service because the participation of professional property managers is only required upon completion of the building. Recently, however, property management has become an integral part of project development based on its value. These days, managing recreational facilities such as residents’ clubs, gyms and swimming pools, given the frequent use of electronic installations, no longer falls under basic caretaking services. The early detection of hidden problems such as poor quality concealed cables, conduits and pipes and the improper selection of building materials saves time and money in subsequent maintenance and repair work, simultaneously reducing any inconvenience experienced by end-users due to a breakdown in services or defective rectification.

  13. The effects of aircraft noise at Williams Air Force Base Auxiliary Field on residential property values

    Energy Technology Data Exchange (ETDEWEB)

    Morey, M.J.

    1990-11-01

    This report considers the environmental consequences of moving the flight training operations of the US Air Force's 82nd Flying Training Wing from the auxiliary airfield, Coolidge-Florence Municipal Airport (CFMA), to a more remote location in Pinal County, Arizona. It examines how actual noise from touch-and-go flights of T-37 aircraft and perceived (anticipated) noise affect the market value of residential property near CFMA. Noise, measured by a noise index, is correlated with market values through a regression analysis applied to a hedonic price model of the Coolidge-Florence housing market. Prices and characteristics of 42 residential properties sold in 1987 and 1988 were used to estimate a perceived noise effect. The report finds that the coefficient on the measure of perceived noise, based on the noise exposure forecast (NEF) index, is statistically insignificant, even though the sign and value are consistent with those estimated in other studies. It concludes that current flights do not have a significant effect on residential property values, partially because there is no housing near CFMA. This and larger studies indicate that flight operations at a new auxiliary airfield would not affect property values if runways were at least 12,000 feet away from housing. 12 refs., 2 tabs.

    In this study, we present the inherent optical properties of carbonaceous aerosols generated from various coals (hard through bituminous to lignite) and their correlation with the thermochemical and energetic properties of the bulk coal samples. The nanoablation method provided a unique opportunity for the comprehensive investigation of the generated particles under well controlled laboratory circumstances. First, the wavelength dependent radiative features (optical absorption and scattering) and the size distribution (SD) of the generated particulate matter were measured in-situ in aerosol phase using in-house developed and customised state-of-the-art instrumentation. We also investigated the morphology and microstructure of the generated particles using Transmission Electron Microscopy (TEM) and Electron Diffraction (ED). The absorption spectra of the measured samples (quantified by Absorption Angström Exponent (AAE)) were observed to be distinctive. The correlation between the thermochemical features of bulk coal samples (fixed carbon (FC) to volatile matter (VM) ratio and calorific value (CV)) and the AAE of aerosol assembly were found to be (r2 = 0.97 and r2 = 0.97) respectively. Lignite was off the fitted curves in both cases most probably due to its high optically inactive volatile material content. Although more samples are necessary to be investigated to draw statistically relevant conclusion, the revealed correlation between CV and Single Scattering Albedo (SSA) implies that climatic impact of coal combusted aerosol could depend on the thermal and energetic properties of the bulk material.

    2014-01-01

    Wildfire damages to private residences in the United States and elsewhere have increased as a result of expansion of the wildland-urban interface (WUI) and other factors. Understanding this unwelcome trend requires analytical frameworks that simulate how various interacting social, economic, and biophysical factors influence those damages. A methodological framework is developed for simulating expected residential property losses from wildfire [E(RLW)], which is a probabilistic monetary measure of wildfire risk to residential properties in the WUI. E(RLW) is simulated for Flathead County, Montana for five, 10-year subperiods covering the period 2010-2059, under various assumptions about future climate change, economic growth, land use policy, and forest management. Results show statistically significant increases in the spatial extent of WUI properties, the number of residential structures at risk from wildfire, and E(RLW) over the 50-year evaluation period for both the county and smaller subareas (i.e., neighborhoods and parcels). The E(RLW) simulation framework presented here advances the field of wildfire risk assessment by providing a finer-scale tool that incorporates a set of dynamic, interacting processes. The framework can be applied using other scenarios for climate change, economic growth, land use policy, and forest management, and in other areas.

  19. Use of Geographically Weighted Regression (GWR Method to Estimate the Effects of Location Attributes on the Residential Property Values

    Directory of Open Access Journals (Sweden)

    Mohd Faris Dziauddin

    2017-07-01

    Full Text Available This study estimates the effect of locational attributes on residential property values in Kuala Lumpur, Malaysia. Geographically weighted regression (GWR enables the use of the local parameter rather than the global parameter to be estimated, with the results presented in map form. The results of this study reveal that residential property values are mainly determined by the property’s physical (structural attributes, but proximity to locational attributes also contributes marginally. The use of GWR in this study is considered a better approach than other methods to examine the effect of locational attributes on residential property values. GWR has the capability to produce meaningful results in which different locational attributes have differential spatial effects across a geographical area on residential property values. This method has the ability to determine the factors on which premiums depend, and in turn it can assist the government in taxation matters.

  20. E-service quality: An investigation of its key dimensions and the discriminatory power in the residential property sector

    Directory of Open Access Journals (Sweden)

    Justin Beneke

    2011-12-01

    Full Text Available Research Statement: With an increase in competition within the South African property sector, real estate agencies need to ensure that their channels are as effective as possible. Using the Internet and mobile technologies represents a new means to reach customers and achieve lower operating costs. This study seeks to ascertain which factors potential buyers consider important when perusing residential property in an online environment. Hence, the dimensions of e-service quality, which constitute their online experience, will be explored. In addition, this research explores buyer typologies and probes whether other forms of technology, such as a mobile interface, may be of commercial value to the realtor. Methodology: The empirical analysis was conducted by means of a quantitative survey. A questionnaire was designed to test the application of the e-service quality construct in the South African real-estate sector. Data was obtained from 300 respondents, across the age spectrum, who filled the criteria of being prospective buyers. Convenience sampling was primarily used to collect responses as the researchers were unable to obtain access to a specific database of listed property buyers. Results & Conclusion: As mirrored in other studies of this nature, it was found that trust is paramount when initiating property sales online. All other variables in the construct (site features, information, accessibility, communication, reliability, responsiveness and personalisation also proved significant. A cluster analysis revealed that older respondents preferred a higher level of support - across all attributes of e-service quality - when interacting with online property services. Lastly, the mobile interface appears to appeal to 'students' as well as 'mature workers'. It is surmised that these individuals have access to smart phones capable of being used for accessing property portals. However, the 'young workers' appear less enthusiastic about the

  4. Effects on residential property values of proximity to a site contaminated with radioactive waste

    International Nuclear Information System (INIS)

    Payne, B.A.; Olshansky, S.J.; Segel, T.E.

    1985-01-01

    An issue often raised by the public regarding projects that involve hazardous chemical or radioactive waste sites is whether distance from these sites affects residential property values. Previous research has studied changes in the housing market in communities near Three Mile Island after the 1979 accident and legal precedents of compensation for loss of property value because of proximity to hazardous areas. However, this research has not addressed effects on residential property values of proximity specifically to hazardous chemical or radioactive waste sites. The effects of the proximity of residence to such a site in West Chicago, Illinois - used for many years for disposal of thorium waste from processing ores - were investigated in this study. Single-family residence sales located within about 0.4 km of the West Chicago site were compared with residence sales located between 0.4 km and 1.6 km from the site. Trends in average annual selling prices were analyzed both before and after publicity appeared about the existence of the radioactive material at the site. Results indiate that older residences (built before 1950) located within about 0.4 km of the disposal site experienced a prolonged depression in selling prices after the publicity, in comparison with older residences located farther from the site and with all transactions on newer residences. These results confirm to some extent public perceptions and potentially raise legal issues associated with property values. Suggestions are provided for mitigative measures to alleviate these issues. 22 references, 1 figure

    Real-time analyzers of selected chemical components (sulfate, nitrate, Black Carbon) and integrative aerosol parameters (particulate matter and light scattering coefficient) were implemented for a 2-week campaign (November-December 2005) in a suburban area of Clermont-Ferrand (France) in order to document fast changes in the chemical composition of submicron aerosols. Measurements of particulate organic matter (POM) were not available in the field but were indirectly estimated from time-resolved (3-min) reconstruction of the light scattering coefficient. This methodology offered the opportunity to investigate almost real-time and artifact-free POM concentrations even at low concentrations (typically below 0.1 mu g m(-3)). The overall uncertainties associated with this POM calculation were of the order of 20%, which are comparable to those commonly referred in literature for POM calculation or measurements. A chemical mass balance (CMB) of PM1 was performed using the derived POM concentrations and showed a very good correlation (slope = 0.93; r(2) = 0.91, N = 663) with real-time PM1 measurements obtained from R and P TEOM-FDMS, demonstrating the consistency of our approach. Important diurnal variations were observed in POM concentrations, with a dominant contribution of POM from fossil fuel origin during daytime and a dominant contribution of POM from residential wood burning at night. POM was calculated to contribute as much as 70% of PM1 during our study, pointing out the major role of carbonaceous aerosols at this period of the year at our residential area. (authors)

    This paper presents an optimal load management strategy for residential consumers that utilizes the communication infrastructure of the future smart grid. The strategy considers predictions of electricity prices, energy demand, renewable power production, and power-purchase of energy of the consumer in determining the optimal relationship between hourly electricity prices and the use of different household appliances and electric vehicles in a typical smart house. The proposed strategy is illustrated using two study cases corresponding to a house located in Zaragoza (Spain) for a typical day in summer. Results show that the proposed model allows users to control their diary energy consumption and adapt their electricity bills to their actual economical situation. - Highlights: ► This work shows an optimal load management strategy for residential consumers. ► It has been considered the communication infrastructure of the future smart grid. ► A study case shows the optimal utilization of some appliances and electric vehicles. ► Results showed that the proposed model allows users to reduce their electricity bill.

  15. Property Tax Assessments as a Finance Vehicle for Residential PV Installations: Opportunities and Potential Limitations

    increased property tax assessments, rather than a more-traditional credit vehicle, to recover both system and administrative costs. As discussed in more detail later, this seemingly innovative approach has a number of features that should appeal to PV owners, including: long-term, fixed-cost, attractive financing; loans that are tied to the tax capacity of the property rather than to the owner's credit standing; a repayment obligation that transfers along with the sale of the property; and a potential ability to deduct the repayment obligation from Federal taxable income, as part of the local property tax deduction. For these reasons, Berkeley's program--which was first announced on October 23, 2007--has received considerable nationwide attention in both the trade and general press. Since the announcement, cities from throughout California and the broader U.S. have expressed keen interest in the possibility of replicating this type of program. In California alone, the cities of Santa Cruz, Santa Monica, and Palm Desert are all reportedly considering similar programs, while the city of San Francisco has recently announced its own program, portions of which closely parallel Berkeley's approach. Berkeley's Proposed PV Program In addition, a bill (AB 811) that would authorize all cities (not just 'charter cities' like Berkeley) in California to create this type of program was approved by the California General Assembly on January 29, 2008 and passed on to the State Senate for consideration. That local governments from across California and the broader US are so genuinely excited about the prospect of supporting the installation of residential PV in their communities through this type of program is no doubt an interesting development. Given, however, the potential for such programs to negatively interact with the residential solar ITC, it is important to evaluate the financial attractiveness of this specific type of loan program, particularly in

  3. Nearly Zero Energy Standard for Non-Residential Buildings with high Energy Demands—An Empirical Case Study Using the State-Related Properties of BAVARIA

    Directory of Open Access Journals (Sweden)

    Michael Keltsch

    2017-03-01

    Full Text Available The Energy Performance of Buildings Directive (EPBD 2010 calls for the Nearly Zero Energy Building (nZEB Standard for new buildings from 2021 onwards: Buildings using “almost no energy” are powered by renewable sources or by the energy produced by the building itself. For residential buildings, this ambitious new standard has already been reached. But for other building types, this goal is still far away. The potential of these buildings to meet a nZEB Standard was investigated by analyzing ten case studies, representing non-residential buildings with different uses. The analysis shows that the primary characteristics common to critical building types are a dense building context with a very high degree of technical installation (such as hospital, research, and laboratory buildings. The large primary energy demand of these types of buildings cannot be compensated by building- and property-related energy generation, including off-site renewables. If the future nZEB Standard were to be defined with lower requirements because of this, the state-related properties of Bavaria suggest that the real potential energy savings available in at least 85% of all new buildings would be insufficiently exploited. Therefore, it would be more useful to individualize the legal energy verification process for new buildings, to distinguish critical building types such as laboratories and hospitals from the other building types.

  4. Tests for the Presence of Price Convergence on Residential Property Market in Several Districts of Szczecin in 2006–2009

    Directory of Open Access Journals (Sweden)

    Gnat Sebastian

    2016-12-01

    Full Text Available Neighbouring local property markets are not separate realities. They influence one another and create an interrelated system of supply and demand. Some of these interrelations are convergent, while others result in contradictory trends on the markets. Convergence is a term denoting a process of some phenomena approaching its normative level. Tests for the presence of convergence help to assess if the objects under observation show resemblance in the context of the observed phenomenon, and to find out how long it takes for this resemblance to be complete. In this paper, I propose the application of methods normally used in tests for convergence for the purpose of the analysis of trends of the average residential property prices in some districts in Szczecin over the time range of 2006–2009, that is during the housing bubble on the residential property market. The study will provide information if such a market phase encourages price convergence.

  7. Setting up charging electric stations within residential communities in current China: Gaming of government agencies and property management companies

    International Nuclear Information System (INIS)

    Wu, Tian; Ma, Lin; Mao, Zhonggen; Ou, Xunmin

    2015-01-01

    The difficulty of charging electric vehicles (EVs) is now hindering their further development. Governments generally choose to build stations for home charging (including piles) within residential communities. Given the conflict of interest between various government agencies and property management companies, constructing a charging station within residential communities would result in welfare loss for the property management companies and therefore lead to the principal–agent problem. This paper constructs a two-period imperfect information game theory model to study the moral hazard involved in this issue and government agencies' optimal choice. In the analytic solution of the model, we find that the optimal choice for a farsighted government agency is to constantly improve the incentive mechanism and introduce charging stations only when the conflict of interest is eliminated. Any benefits derived from government regulations by force would prove short-lived. The government should focus on long-term returns in the development of EVs, and its optimal mechanism should be designed to mitigate the principal–agent problem of property management companies, thereby accelerate the progress of EV charging infrastructure and improve overall social welfare. - Highlights: • The charging of electric vehicles (EVs) is hindering their use. • A game theory model is used for analysis of EV charging station construction. • Charging stations are in residential communities in China. • Government agencies are constantly improving incentive mechanisms

  8. Methods of modeling TCO residential real estate in the life cycles of buildings as a promising energy efficiency management tool

    Directory of Open Access Journals (Sweden)

    Kulakov Kirill

    2017-01-01

    Full Text Available Building and developing an affordable housing market is a huge challenge for Russia’s national economy. Today, the housing construction industry finds itself in a situation torn by a conflict caused by the simultaneous needs to minimize the housing construction costs in order to make housing more affordable for Russians and to increase the energy efficiency of the housing projects, which is associated with additional costs for developers. To find solutions to this contradictory situation, one needs new theoretical and practical approaches and economic tools. The global economic trend of managing goods and services on the basis of the value of goods and services over the life cycle is also manifested in the construction industry in Russia. The problem of forming a new economic thinking in the housing sector predetermines the perception of the value of housing not only as the price of purchased real estate, but as the equivalent of the total cost of ownership of real estate throughout its life cycle. This approach allows to compensate the initial rise in the cost of construction resulting from the introduction of energy-efficient technologies by savings in the operational phase of the life cycle of the property. In this regard, management of the total cost of real estate ownership based on energy modeling is of high research and practical relevance.

  13. Assessing the PACE of California residential solar deployment: Impacts of Property Assessed Clean Energy programs on residential solar photovoltaic deployment in California, 2010-2015

    Energy Technology Data Exchange (ETDEWEB)

    Deason, Jeff; Murphy, Sean

    2018-04-04

    A new study by Berkeley Lab found that residential Property Assessed Clean Energy (R-PACE) programs increased deployment of residential solar photovoltaic (PV) systems in California, raising it by about 7-12% in cities that adopt these programs. R-PACE is a financing mechanism that uses a voluntary property tax assessment, paid off over time, to facilitate energy improvements and, in some jurisdictions, water and resilience measures. While previous studies demonstrated that early, regional R-PACE programs increased solar PV deployment, this new analysis is the first to demonstrate these impacts from the large, statewide R-PACE programs dominating the California market today, which use private capital to fund the upfront costs of the improvements. Berkeley Lab estimated the impacts using econometric techniques on two samples: -Large cities only, allowing annual demographic and economic data as control variables -All California cities, without these annual data Analysis of both samples controls for several factors other than R-PACE that would be expected to drive solar PV deployment. We infer that on average, cities with R-PACE programs were associated with greater solar PV deployment in our study period (2010-2015). In the large cities sample, solar PV deployment in jurisdictions with R-PACE programs was higher by 1.1 watts per owner-occupied household per month, or 12%. Across all cities, solar PV deployment in jurisdictions with R-PACE programs was higher by 0.6 watts per owner-occupied household per month, or 7%. The large cities results are statistically significant at conventional levels; the all-cities results are not. The estimates imply that the majority of solar PV deployment financed by R-PACE programs would likely not have occurred in their absence. Results suggest that R-PACE programs have increased PV deployment in California even in relatively recent years, as R-PACE programs have grown in market share and as alternate approaches for financing solar PV

    An agent-based model is constructed in which a demand aggregator sells both uniform-price and real-time price (RTP) contracts to households as means for adding price elasticity in residential power use sectors, particularly during peak-price hours of the day. Simulations suggest that RTP contracts help a demand aggregator (1) shift its long-term contracts toward off-peak hours, thereby reducing its cost of power and (2) increase its short-run profits if it is one of the first aggregators to have large numbers of RTP contracts; but (3) create susceptibilities to short-term market demand and price volatilities.

  8. Background information for programs to improve the energy efficiency of Northwest residential rental property

    Energy Technology Data Exchange (ETDEWEB)

    Hendrickson, P.L.

    1986-02-01

    This report was prepared for the Office of Conservation, Bonneville Power Administration. The report will be used by the Office as background information to support future analysis and implementation of electricity conservation programs for owners of residential rental housing in the Northwest. The principal objective of the study was to review market research information relating to attitudes and actions of Northwest rental housing owners and, to a lesser extent, tenants toward energy conservation and energy-efficiency improvements. Available market research data on these subjects were found to be quite limited. The most useful data were two surveys of Seattle rental housing owners conducted in late 1984 for Seattle City Light. Several other surveys provided supplemental market research information in selected areas. In addition to market research information, the report also includes background information on rental housing characteristics in the Northwest.

  10. YORP effect on real objects. I. Statistical properties

    Science.gov (United States)

    Micheli, M.; Paolicchi, P.

    2008-10-01

    Context: The intensity of the YORP (Yarkovsky, O'Keefe, Radzievskii, and Paddack) effect and its ability to affect the rotational properties of asteroids depend mainly on the size of the body and on its shape. At present, we have a database of about 30 well-defined shapes of real minor bodies (most of them asteroids, but also planetary satellites and cometary nuclei). Aims: In this paper we perform a statistical analysis of how the YORP effect depends on the shape. Methods: We used the Rubincam approximation (i.e. neglecting the effects of a finite thermal conductivity). Results: We show that, among real bodies, the distribution of the YORP types, according to the classification of Vokrouhlický and Čapek, is significantly different from the one obtained in the same paper from theoretical modeling of shapes. A new “type” also comes out. Moreover, we show that the types are strongly correlated with the intensity of the YORP effect (when normalized to eliminate the dependence on the size, and thus only related to the shape).

    2015-01-01

    Since 1996, real estate development has transformed the United Arab Emirates (UAE) into a regional trade and logistics hub. Between January 2003 and December 2010 Dubai Residential Property Price Index (DRPPI) rose from 100 to a heady 240 in 2008 and then dropped back to 156.19 by 2010. The value of two bedroom apartments in the iconic 'Burj Khalif, the world's tallest building, rose to $3,811 and fell back down to $762 per per square foot. During the 2008 property collapse, residential price...

  12. The Effect Of The Original Acquisition Of Ownership Of Immovable Property On Existing Limited Real Rights

    Directory of Open Access Journals (Sweden)

    Gerrit Pienaar

    2015-12-01

    Full Text Available It is an accepted principle in South African law that movable property acquired in an original way (by operation of law is not burdened by any limited real rights, as previous limited real rights are extinguished on the vesting of ownership (mobilia non habent sequelam. It is assumed by some South African writers that the same principles are applicable to the original acquisition of immovable property and that all existing limited real rights fall away on original acquisition of ownership. In this article the nature of limited real rights to immovable property is examined, and the notion that ownership is the "mother" right on which all limited real rights are based is scrutinised critically. The nature and establishment of limited real rights are used to distinguish between the essence and effect of limited real rights in the case of immovable property. The recognition of limited real rights as constitutional property is used as a further argument that limited real rights cannot be extinguished automatically by the original acquisition of immovable property, as such common law or statutory measures will constitute an arbitrary deprivation of property in terms of section 25 of the Constitution. The statutory provisions regarding limited real rights in the case of prescription and expropriation are then analysed as an indication that it is not a general principle that limited real rights are extinguished automatically on the original acquisition of ownership of immovable property.

    High impact flood has virtually become an annual experience in Malaysia, yet flood insurance has remained a grossly neglected part of comprehensive integrated flood risk management. Using discriminant analysis, this study seeks to indentify the demand-side variables that best predict flood insurance penetration and risk aversion between two groups of residential homeowners in three districts of Johor State, Malaysia: those who purchased flood insurance and the group that did not. Our result revealed 34% penetration rate with Kota Tinggi district having the highest penetration (44%) and thus, the highest degree of flood risk aversion. The Wilks' Lambda F test for equality of group means, SCDFC, structure correlation and canonical correlation have clearly shown that there are strong significant attribute differences between the two groups of homeowners based on measures of objective flood risk exposure, subjective risk perception, and socio-economic cum demographic variables. However, measures of subjective risk perception were found more predictive of flood insurance penetration and flood risk aversion.

    1997-11-01

    This report summarizes the underlying historical and regulatory framework supporting the concept of authorizing release for restricted or unrestricted reuse or recycle of real and non-real U.S. Department of Energy (DOE) properties containing residual radioactive material. Basic radiation protection principles as recommended by the International Commission on Radiological Protection are reviewed, and international initiatives to investigate radiological clearance criteria are reported. Applicable requirements of the U.S. Nuclear Regulatory Commission, the Environmental Protection Agency, DOE, and the State of Washington are discussed. Several processes that have been developed for establishing cleanup and release criteria for real and non-real DOE property containing residual radioactive material are presented. Examples of DOE real property for which radiological cleanup criteria were established to support unrestricted release are provided. Properties discussed include Formerly Utilized Sites Remedial Action Project sites, Uranium Mill Tailings Remedial Action Project sites, the Shippingport decommissioning project, the south-middle and south-east vaults in the 317 area at Argonne National Laboratory, the Heavy Water Components Test Reactor at DOE`s Savannah River Site, the Experimental Boiling Water Reactor at Argonne National Laboratory, and the Weldon Spring site. Some examples of non-real property for which DOE sites have established criteria to support unrestricted release are also furnished. 10 figs., 4 tabs.

  20. Geothermal aquaculture project: Real Property Systems Inc. , Harney Basin, Oregon

    Energy Technology Data Exchange (ETDEWEB)

    1981-08-14

    Real Property Systems Inc., (RPS) owns two parcels in the vicinity of Harney Lake, Oregon. One parcel is 120 acres in size, the other is 200 acres. A study concludes that the 200 acre parcel has the greater potential for geothermal development. RPS is interested in an aquaculture operation that produces fresh water prawns, (Macrobrachium rosenbergii) for the market. To supply the heat necessary to maintain the ideal temperature of 82/sup 0/F desired for these prawns, a geothermal resource having a 150/sup 0/F temperature or higher, is needed. The best estimate is that 150/sup 0/F water can be found from a minimum 1090 feet depth to 2625 feet, with no absolute assurances that sufficient quantities of geothermal waters exist without drilling for the same. This study undertakes the preliminary determination of project economics so that a decision can be made whether or not to proceed with exploratory drilling. The study is based on 10 acres of ponds, with a peak requirement of 2500 gpm of 150/sup 0/F geothermal water.

  1. The Impact of Wind Power Projects on Residential Property Values in the United States: A Multi-Site Hedonic Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Hoen, Ben; Wiser, Ryan; Cappers, Peter; Thayer, Mark; Sethi, Gautam

    2009-12-02

    With wind energy expanding rapidly in the U.S. and abroad, and with an increasing number of communities considering wind power development nearby, there is an urgent need to empirically investigate common community concerns about wind project development. The concern that property values will be adversely affected by wind energy facilities is commonly put forth by stakeholders. Although this concern is not unreasonable, given property value impacts that have been found near high voltage transmission lines and other electric generation facilities, the impacts of wind energy facilities on residential property values had not previously been investigated thoroughly. The present research collected data on almost 7,500 sales of singlefamily homes situated within 10 miles of 24 existing wind facilities in nine different U.S. states. The conclusions of the study are drawn from eight different hedonic pricing models, as well as both repeat sales and sales volume models. The various analyses are strongly consistent in that none of the models uncovers conclusive evidence of the existence of any widespread property value impacts that might be present in communities surrounding wind energy facilities. Specifically, neither the view of the wind facilities nor the distance of the home to those facilities is found to have any consistent, measurable, and statistically significant effect on home sales prices. Although the analysis cannot dismiss the possibility that individual homes or small numbers of homes have been or could be negatively impacted, it finds that if these impacts do exist, they are either too small and/or too infrequent to result in any widespread, statistically observable impact.

  2. The Impact of Subway Lines on Residential Property Values in Tianjin: An Empirical Study Based on Hedonic Pricing Model

    Directory of Open Access Journals (Sweden)

    Hui Sun

    2016-01-01

    Full Text Available The construction of subways has an external impact on the urban environment. Among them, the most important acceleration function lies in the property values of housing near subway stations. Tianjin, the largest open coastal city in Northern China, is selected as the subject of the research in this paper by virtue of its unique background. The Hedonic Pricing Model is used in analysing the change in the value of the properties located within 1,000 metres of completed subway line 3 stations. Using the theories of land rent and land location, and a model of the impact of urban traffic on the surrounding real estate prices, we analyse the sphere of influence of Tianjin Metro Line 3 on real estate prices. Finally, the paper stresses the importance of urban construction and subway building and finds that different development strategies should be used according to the characteristics of the subway in various regions of the city.

  4. The impact of gated Communities on property values: evidence of changes in real estate markets -Los Angeles, 1980-2000

    Directory of Open Access Journals (Sweden)

    Renaud Le Goix

    2007-05-01

    Full Text Available The paper focuses on how gated communities, as private means of providing public infrastructure and security, real estate products and club-economies, produce changes in housing market patterns. Based on an empirical study of Los Angeles (California data, it aims to trace to what extent gates and walls favor property values and if the presence of gated communities produces over time (1980-2000 a deterrent effect on non-gated properties abutting the enclave, or close to it. Resulting from a demand for security, gated communities are a leading offer from the homebuilding industry. But their spread emerges from a partnership between local governments and land developers. Both agree to charge the homebuyer with the cost of urban sprawl (construction and maintenance costs of infrastructure within the gates. Such a structuring of residential space is particularly desirable on the urban edges, where the cost of urban sprawl exceeds the financial assets of local public authorities. New private developments provide local governments with new wealthy taxpayers at almost no cost. As compensation, the homebuyer is granted private and exclusive access to sites and amenities (lakes, beaches, etc.. Such exclusivity favors the location rent, and usually positively affects the property values within the gated enclaves. But it is also assumed that operating cost of private governance are paid for by the increase of property values. Market failure nevertheless occurs when costs rise above sustainable levels compared to property values. Changes produced by gates yield to at least two outcomes. At first sight, residential enclosures produce a price premium, thus being a smart investment. Furthermore, gated communities might well be able to generate enough property value to pay off the price of private governance. But this analysis holds only on a short term basis. In the long term, larger and wealthier gated communities are successful in shielding their property

    Directory of Open Access Journals (Sweden)

    Şteliac Nela

    2013-04-01

    Full Text Available The residential market is one of the market sectors seriously affected by the current economic and financial crisis. This is mirrored both in the fall of real estate trading prices and in the decreased number of transactions and cutback of newly built constructions. This trend is applicable to the entire spectrum of the residential market (luxury properties and homes destined to average-income customers. Romania is no exception from this European and world-wide state of affairs. This paper aims to briefly outline the trends on the Romanian residential market in the aftermath of the current crisis.

    2009-08-01

    The purpose of this prospective cohort study was to describe the clinimetric evaluation of four fall risk assessment tools (FRATs) recommended in best practice guidelines for use in residential aged care (RAC). Eighty-seven residents, mean age 81.59 years (SD +/-10.69), participated. The Falls Assessment Risk and Management Tool (FARAM), Peninsula Health Fall Risk Assessment Tool (PHFRAT), Queensland Fall Risk Assessment Tool (QFRAT), and Melbourne Fall Risk Assessment Tool (MFRAT) were completed at baseline, and 2 and 4 months, and falls occurring in the 6 months after the baseline assessment were recorded. Interrater agreement (kappa), predictive accuracy (survival analysis and Youden Index), and fit to the Rasch model were examined. Twelve-month fall history formed the predictive accuracy reference. Interrater risk classification agreement was high for the PHFRAT (small ka, Cyrillic = .84) and FARAM (small ka, Cyrillic = .81), and low for the QFRAT (small ka, Cyrillic = .51) and MFRAT (small ka, Cyrillic = .21). Survival analysis identified that 43%-66% of risk factors on each tool had no (p > .10) association with falls. No tool had higher predictive accuracy (Youden index) than the question, "has the resident fallen in past 12 months?" (p > .05). All tools did not exhibit fit to the Rasch model, invalidating summing of risk factor scores to provide an overall risk score. The studied tools have poor clinimetric properties, casting doubt about their usefulness for identifying fall risk factors for those most at risk for falling and measuring fall risk in RAC.

    2012-01-01

    The psychometric properties of the Drug Use Disorders Identification Test (DUDIT), an 11-item self-report questionnaire developed to screen individuals for drug problems, are evaluated. The measure, developed in Sweden and evaluated there with individuals with severe drug problems, has not been evaluated with less severe substance abusers or with clinical populations in the United States. Participants included 35 drug abusers in an outpatient substance abuse treatment program, 79 drug abusers in a residential substance abuse treatment program, and 39 alcohol abusers from both treatment settings who did not report a drug abuse problem. The DUDIT was found to be a psychometrically sound drug abuse screening measure with high convergent validity (r=.85) when compared with the Drug Abuse Screening Test (DAST-10), and to have a Cronbach's alpha of .94. In addition, a single component accounted for 64.91% of total variance, and the DUDIT had sensitivity and specificity scores of .90 and .85, respectively, when using the optimal cut-off score of 8. Additionally, the DUDIT showed good discriminant validity as it significantly differentiated drug from alcohol abusers. These findings support the DUDIT as a reliable and valid drug abuse screening instrument that measures a unidimensional construct. Further research is warranted with additional clinical populations.

    The optical properties, composition and sources of the wintertime aerosols in the San Joaquin Valley (SJV) were characterized through measurements made in Fresno, CA during the 2013 DISCOVER-AQ campaign. PM2.5 extinction and absorption coefficients were measured at 405, 532, and 870 nm along with refractory black carbon (rBC) size distributions and concentrations. BC absorption enhancements (Eabs) were measured using two methods, a thermodenuder and mass absorption coefficient method, which agreed well. Relatively large diurnal variations in the Eabs at 405 nm were observed, likely reflecting substantial nighttime emissions of wood burning organic aerosols (OA) from local residential heating. Comparably small diurnal variations and absolute nighttime values of Eabs were observed at the other wavelengths, suggesting limited mixing-driven enhancement. Positive matrix factorization analysis of OA mass spectra from an aerosol mass spectrometer resolved two types of biomass burning OA, which appeared to have different chemical composition and absorptivity. Brown carbon (BrC) absorption was estimated to contribute up to 30% to the total absorption at 405 nm at night but was negligible (mixing state and the distribution of coating thicknesses.

  13. Investing in European market real property through reits

    Science.gov (United States)

    Adamuscin, A.

    2010-03-01

    For institutional and private investors, investing in real estate represents an attractive form of the consignment of their money. Real estate provides a regular source of income in the form of the rent from or interest on the credit provided. At the same time, real estate is a good investment instrument, because it provides diversified contributions and security against inflation for investors. In their efforts to diversify risk, investors are expressing growing interest in investing in the whole European Union. The success of Real Estate Investment Trusts (REITs) in the U.S. also opened the door for investing in this market for small investors, which is the reason for the development of this type of investment company in the European arena. One problem concerning the development of European real estate investment funds is the unsolved issue of the harmonization of the legislation and regulatory safety measures, which would enable the creation of a common market for new investment products in Europe.

    With increasing numbers of communities considering wind power developments, empirical investigations regarding related community concerns are needed. One such concern is that proximate property values may be adversely affected, yet relatively little research exists on the subject. The present research investigates roughly 7,500 sales of single-family homes surrounding 24 existing U.S. wind facilities. Across four different hedonic models, and a variety of robustness tests, the results are consistent: neither the view of the wind facilities nor the distance of the home to those facilities is found to have a statistically significant effect on sales prices, yet further research is warranted.

  1. Real Estate Crowdfunding. A financial innovation for direct property investment

    Directory of Open Access Journals (Sweden)

    Giacomo Morri

    2016-12-01

    Full Text Available The aim of this work is to provide a simple overview on crowdfunding with a focus on its potential application to the real estate market. The Global Financial Crisis of 2008 paralyzed the global economy, creating a strong diminishing trust in financial services and in the banking system in general. One of the most revolutionary systems to get funded in the market has been crowdfunding, a way of financing coming directly from the crowd through the Internet. Crowdfunding in real estate started in 2012 with the Jumpstart Our Business Startup Act (JOBS Act in USA and has been developing at a fast rate every year. In Italy, crowdfunding for real estate projects is not allowed yet, but there are various platforms that are already using the concept in different ways. Real Estate Crowdfunding could represent an interesting opportunity for private individual to have an exposure to direct real estate investments. After an initial description of crowdfunding in general, we present real estate crowdfunding in the U.S. by presenting the most relevant cases up to date. Finally, we analyze the Italian market by explaining why this innovative way of financing real estate projects is not feasible yet and how some platforms are legally trying to overcome the current limitations. In the U.S. the RECF has already raised more than $1 billion and there are more than 125 platforms; in Italy there are still limits for startups dealing with crowdfunding and a few platforms are starting to operate with a similar model.

    Light-absorbing materials such as black carbon (BC) and brown carbon (BrC) in atmospheric aerosols play important roles in regulating the earth's radiative budget and climate. However, the representations of BC and BrC in state-of-the-art climate models remain highly uncertain, in part due to the poor understanding of their microphysical and optical properties. Direct observations and characterizations of the mixing state and absorption enhancement of ambient aerosols could provide invaluable constraints for current model representations of aerosol radiative effects. Here, we will discuss results from measurements of aerosol light absorption and absorption enhancement (Eabs), using a thermodenuder-absorption method, made during two recent field studies in central and southern California. The winter study took place in Dec/Jan of 2014/2015 in Fresno, CA. This region is severely impacted by particulate matter from local and regional residential biomass burning. The summer study took place in July 2015 in Fontana, CA, a region ~80 km downwind of Los Angeles and strongly impacted by vehicular emissions, and thus provides a sharp contrast to the Fresno study. Eabs of BC particles due to the "lensing" effect from coatings to BC core and/or the presence of BrC will be quantified and compared between the two studies. Additionally, the chemical composition of bulk and the BC-containing particles are determined via a HR-ToF-AMS and a SP-AMS, respectively. Variations in the composition and mixing state of the ambient particles and how these affect the observed Eabs will be examined. The overall measurements suggest a relatively small role for lensing-induced absorption enhancements for ambient particles in these regions.

    Full Text Available Ever since the Soviet Union design solutions were evaluated according to different criteria and indicators. At the present stage of evaluation systems of design solutions stands systemengineering doctrine is allocated. It is complemented by the theory of efficiency and financial sustainability investment project in view of the general market concept. Also great attention is paid to the virtual object modeling. It is urgent to include the behavior prediction of an investment construction project model at each stage of its life cycle. The high cost of all phases of this life cycle makes it necessary to calculate the feasibility of the investment. Very urgent to do it as accurately as possible and before we start of design works on the stage of the investment plan evaluation. Belarus has legislated pre-investment stage of construction project development. To evaluate the design solution at this stage is necessary to develop an investment justification, a project management plan and a business plan. They will evaluate and will compare several options for future objects by the complex. This requires not only time, but considerable financial costs. In order to optimize the process to develop an evaluation system design solutions based on existing projects. It allows the customer (investor choose design solutions to build the object without developing of pre-design documentations for several options. This system it is advisable to try out the example of apartment house building with the assistance of the national fund of project documentation and objects-analogues data bank. The developed evaluation system of design solutions for residential real estate objects in the pre-investment stage is supposed to use the theory of neural networks and neyroprogramming. This system bases on the input parameters projects. The hidden layer neurons are trained to choose suitable projects of apartment houses with their classification. The projects will be classified

    Full Text Available In the process of real estate evaluation, there are many important elements that should be taken into consideration: for example the type of property which is under evaluation, real estate market analysis, and the selection of appropriate evaluation approaches, methods and techniques. In each of the approaches, different parameters are important. Most importantly, however, is the appropriate selection and identification of real estate characteristics, both physical and economic, as well as the determination of the importance of these qualities so that, when necessary, it will be possible to make the appraisal and select those characteristics which have the greatest impact on value of property.

  16. A System of Indicators for Financial Analysis of the Municipal Real Property

    Directory of Open Access Journals (Sweden)

    Daniela Feschiyan

    2013-08-01

    Full Text Available The paper presents a system of financial indicators for the efficiency of use of municipal real property. Such a system must provide for meeting the information needs of a number of internal and external consumers and is of primary significance in the analysis of municipalities’ overall financial condition. The following may be pointed out as the major aspects of the practical analysis: i the analysis of the municipality’s provision with immoveable property; ii the analysis of the efficient use of certain categories of municipal real property. The paper aims at clarifying the major moments in the analysis of the structure, composition, and effective use of municipal real property, and the determination of definite indicators to be applied to this analysis oriented towards its implementation. The wide variety of parameters is reduced to a system of 16 indicators: reporting value, depreciation, ratio of replacement, ratio of cost efficiency, ratio of revenue efficiency, return on total assets, return on revenues, return on expenses, ratio of the fitness, ratio of the repair, ratio of real energy provision, ratio of workload, present value of a series of regular cash flows, equivalent yield model, return on investment, return on investment. The paper presents the structure and content of the indicators of the analysis of the municipal real property, as well as the input of these indicators. The estimation (values necessary to determine the indicators, the indicators themselves and their meaning make it possible to study the effectiveness of the operations (functioning of the municipal real property in terms of description of its physical condition, structure, content, purpose and functions, which generates revenues or brings expenditures to the municipality. The system of indicators provides for decision making with a view to boosting the efficiency of public sector management and more specifically – the management of municipal real property.

    Directory of Open Access Journals (Sweden)

    Daniela Luminiţa Constantin

    2012-11-01

    Full Text Available The paper proposes a comparative analysis of three different scenarios for the efficient use of the former Bucharest City Hall building (BCHb for business purpose. All three scenarios are related to the area of services, namely real estate, retail, cultural services and hotel services. In order to expose the scenario that leads to the best use of the former BCHb a classical model of development appraisal was elaborated. For each scenario, market and financial analysis were conducted. In order to obtain a complex and well documented pre – feasibility study regarding the BCHb three scenarios have been designed, as follows: the first is a mix between offices at the upper levels and retail space at the ground floor of the BCHb; the second is composed of offices at the upper levels and museum at the ground floor; and the third scenario is projected for hotel destination. Starting from the national perspective and continuing with the analysis up to the particular area of the BCHb, the major characteristics of the office, retail and hotel markets were revealed. The financial analysis implied calculations of the most representative indicators used in this type of study, such as net present value, internal rate of return or payback period. Considering the financial indicators comparison, the pre-feasibility study pointed out that the BCHb should follow the scenario with the mix between offices and retail space

  8. Establishing Tenant Ownership on the Basis of Proportional Co-ownership Share of the Real Property

    Directory of Open Access Journals (Sweden)

    Davorin Pichler

    2015-01-01

    Full Text Available The survey of the Osijek District and County Courts procedures related to the motion to determine the usable values of flats and into procedures of establishing separate parts of real property by the means of apportioning plans as well as the tenant ownership study procedures resulted in different and inconsistent approaches in the process of creation of the study and establishing the usable surface area. The paper deals with the analysis of judicial decisions on determining usable surface and indicates the problems emerging in practice while establishing the tenant ownership based on proportional co-ownership share of the real property. It also gives suggestions to passing a by-law on the procedure of tenant ownership study creation i.e. calculation of usable values of particular real property shares and usable values of all flats and other independent premises of the entire real property. Its goals are equal interpretation and application of tenant ownership by all parties to the procedure as well as legal security, uniform application of law and harmonisation of judicial practice. As a possible approach to the solutions in Croatian legal system the paper also analyses the regulation of tenant ownership in the Republic of Slovenia. In conclusion, it establishes the need for professional training of judges, court counsellors, court appointed expert witnesses, civil servants through application of a multidisciplinary approach to the issue of tenant ownership procedure based on other scientific disciplines e.g. civil engineering and economics.

    Osteoblast, playing a key role in the pathophysiology of osteoporosis, is one of the mechanical stress sensitive cells. The effects of mechanical load-induced changes of mechanical properties in osteoblast cells were studied at real-time. Osteoblasts obtained from young Wister rats were exposed to mechanical loads in different frequencies and resting intervals generated by atomic force microscopy (AFM) probe tip and simultaneously measured the changes of the mechanical properties by AFM. The enhancement of the mechanical properties was observed and quantified by the increment of the apparent Young's modulus, E{sup *}. The observed mechanical property depended on the frequency of applied tapping loads. For the resting interval is 50 s, the mechanical load-induced enhancement of E{sup *}-values disappears. It seems that the enhanced mechanical property was recover able under no additional mechanical stimulus.

    Real-time estimation of dynamical characteristics of thalamocortical cells, such as dynamics of ion channels and membrane potentials, is useful and essential in the study of the thalamus in Parkinsonian state. However, measuring the dynamical properties of ion channels is extremely challenging experimentally and even impossible in clinical applications. This paper presents and evaluates a real-time estimation system for thalamocortical hidden properties. For the sake of efficiency, we use a field programmable gate array for strictly hardware-based computation and algorithm optimization. In the proposed system, the FPGA-based unscented Kalman filter is implemented into a conductance-based TC neuron model. Since the complexity of TC neuron model restrains its hardware implementation in parallel structure, a cost efficient model is proposed to reduce the resource cost while retaining the relevant ionic dynamics. Experimental results demonstrate the real-time capability to estimate thalamocortical hidden properties with high precision under both normal and Parkinsonian states. While it is applied to estimate the hidden properties of the thalamus and explore the mechanism of the Parkinsonian state, the proposed method can be useful in the dynamic clamp technique of the electrophysiological experiments, the neural control engineering and brain-machine interface studies.

Therefore as certain property disputes affect substantial property interests of physical and juridical persons which are not under the protection of property rights in the traditional sense there is a need for a broad interpretation of the relevant provisions of the Russian Constitution. However the mixing of proprietary and contractual rights in this case does not occur. Second the Russian Civil Code reproducing and specifying the constitutional provisions as principles of private law form a direct normative basis of the whole civil law. However the constitutional law attributes a broader meaning to the notions of property and property right than the traditional civil law. Third the possible limitations of the Federal law of the rights of ownership use and disposition of property as well as freedom of entrepreneurship and freedom of contract must meet the requirements of justice to be adequate proportionate be of general and abstract character be not retroactive and not affect the essence of constitutional rights i.e. not limit the scope and application of the substantive content of the relevant constitutional norms.The possibility of such limitations and their nature must be determinedby the need to protect the significant values ndash the foundations of the constitutional system morality health rights and lawful interests of other persons provision

    Real thermodynamic and transport properties of hydrogen, steam, the SSME mixture, and air are developed. The SSME mixture properties are needed for the analysis of the space shuttle main engine fuel turbine. The mixture conditions for the gases, except air, are presented graphically over a temperature range from 800 to 1200 K, and a pressure range from 1 to 500 atm. Air properties are given over a temperature range of 320 to 500 K, which are within the bounds of the thermodynamics programs used, in order to provide mixture data which is more easily checked (than H2/H2O). The real gas property variation of the SSME mixture is quantified. Polynomial expressions, needed for future computer analysis, for viscosity, Prandtl number, and thermal conductivity are given for the H2/H2O SSME fuel turbine mixture at a pressure of 305 atm over a range of temperatures from 950 to 1140 K. These conditions are representative of the SSME turbine operation. Performance calculations are presented for the space shuttle main engine (SSME) fuel turbine. The calculations use the air equivalent concept. Progress towards obtaining the capability to evaluate the performance of the SSME fuel turbine, with the H2/H2O mixture, is described.

  2. Valuation Bases and Accounting System Entries in Financial Analysis of the Municipal Real Property

    2013-08-01

    Full Text Available The paper introduces a conceptual framework for an accounting of the municipal real property, and defines a respective system of indicators. The development of this framework is seen as an important prerequisite for the efficient property management. It aims to overcome the lack or poor accessibility of the information, and thus to ensure the successful municipal real property management in a strategic context. The developing of the applied approach implies that accounting indicators are divided into three main groups – values, revenues, and costs. Beside the above mentioned classification, the municipal revenues and costs are classified also as existing and proposed. The existing indicators are defined by International Accounting Standards in public sector, and some of them are considered as being appropriate for the inclusion in the financial analysis as accounting system entries. The proposed indicators are perceived as appropriate to carry out a detailed analysis of the municipal property at a lower level of desegregations. The first two paragraphs explain the main bases for the municipal property valuation - historical cost, current price, market value, present value, with a special emphasis on the use of the historical value, and the types of valuation respectively. The next three paragraphs are concentrated mainly on the accounting indicators for the municipal property assessment. The sixth paragraph represents several major accounting bases - an accounting value, a carrying value, a market value, an accumulated depreciation, revenues from the sale of assets and services, costs by economic elements, revenues from future periods and costs for future periods, and revenues from other events and costs for other events. The seventh section presents a brief comparative analysis of accounting systems of 6 municipalities in South-Eastern Europe and the last paragraph highlights the identified “good practices”.

    2015-01-01

    A novel acquisition and processing method that enables real-time, single snapshot of optical properties (SSOP) and 3-dimensional (3D) profile measurements in the spatial frequency domain is described. This method makes use of a dual sinusoidal wave projection pattern permitting to extract the DC and AC components in the frequency domain to recover optical properties as well as the phase for measuring the 3D profile. In this method, the 3D profile is used to correct for the effect of sample’s height and angle and directly obtain profile-corrected absorption and reduced scattering maps from a single acquired image. In this manuscript, the 3D-SSOP method is described and validated on tissue-mimicking phantoms as well as in vivo, in comparison with the standard profile-corrected SFDI (3D-SFDI) method. On average, in comparison with 3D-SFDI method, the 3D-SSOP method allows to recover the profile within 1.2mm and profile-corrected optical properties within 12% for absorption and 6% for reduced scattering over a large field-of-view and in real-time.

  8. Real-time measurement of materials properties at high temperatures by laser produced plasmas

    Kim, Yong W.

    1990-01-01

    Determination of elemental composition and thermophysical properties of materials at high temperatures, as visualized in the context of containerless materials processing in a microgravity environment, presents a variety of unusual requirements owing to the thermal hazards and interferences from electromagnetic control fields. In addition, such information is intended for process control applications and thus the measurements must be real time in nature. A new technique is described which was developed for real time, in-situ determination of the elemental composition of molten metallic alloys such as specialty steel. The technique is based on time-resolved spectroscopy of a laser produced plasma (LPP) plume resulting from the interaction of a giant laser pulse with a material target. The sensitivity and precision were demonstrated to be comparable to, or better than, the conventional methods of analysis which are applicable only to post-mortem specimens sampled from a molten metal pool. The LPP technique can be applied widely to other materials composition analysis applications. The LPP technique is extremely information rich and therefore provides opportunities for extracting other physical properties in addition to the materials composition. The case in point is that it is possible to determine thermophysical properties of the target materials at high temperatures by monitoring generation and transport of acoustic pulses as well as a number of other fluid-dynamic processes triggered by the LPP event. By manipulation of the scaling properties of the laser-matter interaction, many different kinds of flow events, ranging from shock waves to surface waves to flow induced instabilities, can be generated in a controllable manner. Time-resolved detection of these events can lead to such thermophysical quantities as volume and shear viscosities, thermal conductivity, specific heat, mass density, and others.

  9. Statistical Properties of Real-Time Amplitude Estimate of Harmonics Affected by Frequency Instability

    Science.gov (United States)

    Bellan, Diego; Pignari, Sergio A.

    2016-07-01

    This work deals with the statistical characterization of real-time digital measurement of the amplitude of harmonics affected by frequency instability. In fact, in modern power systems both the presence of harmonics and frequency instability are well-known and widespread phenomena mainly due to nonlinear loads and distributed generation, respectively. As a result, real-time monitoring of voltage/current frequency spectra is of paramount importance as far as power quality issues are addressed. Within this framework, a key point is that in many cases real-time continuous monitoring prevents the application of sophisticated algorithms to extract all the information from the digitized waveforms because of the required computational burden. In those cases only simple evaluations such as peak search of discrete Fourier transform are implemented. It is well known, however, that a slight change in waveform frequency results in lack of sampling synchronism and uncertainty in amplitude estimate. Of course the impact of this phenomenon increases with the order of the harmonic to be measured. In this paper an approximate analytical approach is proposed in order to describe the statistical properties of the measured magnitude of harmonics affected by frequency instability. By providing a simplified description of the frequency behavior of the windows used against spectral leakage, analytical expressions for mean value, variance, cumulative distribution function, and probability density function of the measured harmonics magnitude are derived in closed form as functions of waveform frequency treated as a random variable.

    2017-01-01

    The experiment was setup to investigate the control of human quiet standing through the manipulation of augmented visual information feedback of selective properties of the motion of two primary variables in postural control: center of pressure (COP) and center of mass (COM). Five properties of feedback information were contrasted to a no feedback dual-task (watching a movie) control condition to determine the impact of visual real-time feedback on the coordination of the joint motions in postural control in both static and dynamic one-leg standing postures. The feedback information included 2D COP or COM position and macro variables derived from the COP and COM motions, namely virtual time-to-contact (VTC) and the COP-COM coupling. The findings in the static condition showed that the VTC and COP-COM coupling feedback conditions decreased postural motion more than the 2D COP or COM positional information. These variables also induced larger sway amplitudes in the dynamic condition showing a more progressive search strategy in exploring the stability limits. Canonical correlation analysis (CCA) found that COP-COM coupling contributed less than the other feedback variables to the redundancy of the system reflected in the common variance between joint motions and properties of sway motion. The COP-COM coupling had the lowest weighting of the motion properties to redundancy under the feedback conditions but overall the qualitative pattern of the joint motion structures was preserved within the respective static and dynamic balance conditions.

  12. An Attempt To Exemplify The Economic Principles In Real Property Valuation

    Directory of Open Access Journals (Sweden)

    Kucharska-Stasiak Ewa

    2015-09-01

    Full Text Available The economic theory argues that the value of assets, including the value of real property, is influenced by many factors which determine the behavior of operators engaged in market transactions. The knowledge of basic principles and assumptions which underpin the development of value is essential to understanding the methods and procedures of valuation. The thesis, upon which the authors of this article based their theoretical and practical considerations, is formulated as follows: “The knowledge of economic principles of valuation improves the accuracy of valuation and allows for more appropriate interpretation of its results”. Therefore, these factors should be taken into account by appraisers estimating the value of property. Over a dozen so-called key principles of valuation have been formulated in literature. Among them are the principles of anticipation, change, substitution, supply and demand, competition, balance, highest and best use, conformity, and externalities. It is assumed that the most important principle in the valuation of property is the principle of anticipation. Some of the principles are relevant to all the traditional approaches to determining value, while others apply only to selected approaches e.g., the principle of opportunity cost, which is mainly used in valuations using the income approach. The thesis is supported by research results and an analysis of practical examples.

    The Capital market has the important role in Indonesia's economy. The capital market does not only support the economy of Indonesia but also being an indicator Indonesia's economy improvement. Something that has been traded in the capital market is stock (stock market). Nowadays, the stock market is full of uncertainty. That uncertainty values make predicting stock market is all that we have to do before we make a decision in the stock market. One that can be predicted in the stock market is momentum. To forecast stock market momentum, it can use fuzzy logic model. In the process of modeling, it will be used 14 days historical data that consisting the value of open, high, low, and close, to predict the next 5 days momentum categories. There are three momentum categories namely Bullish, Neutral, and Bearish. To illustrate the fuzzy logic model, we will use stocks data from several companies that listed on Indonesia Stock Exchange (IDX) in property and real estate sector.

    2017-04-01

    This paper reports data describing development projects for new buildings according to construction costs in North-East Italy. A survey was carried out on local companies undertaking new residential development projects in two Italian regions (Veneto and Lombardy). The aim of this survey was to record new real estate construction projects, collecting both technical and socio-economic cost features. It is extremely difficult to collect such data for the Italian real estate construction sector, due to its lack of transparency, so that the novelty for the Italian scenario is the dataset itself. Another interest perspective of this survey is that socio-economic characteristics were also recorded; they are often studied in urban economics, but are usually related to property purchase prices and values, not to construction costs. The data come from an analysis of Canesi and Marella regarding the relationship between the trend of construction costs and the socio-economic conditions of the reference setting, such as the mean years of schooling of the workforce, housing market trends, and average per capita income.

    Residential behavior-based (BB) programs use strategies grounded in the behavioral social sciences to influence household energy use. Strategies may include providing households with real-time or delayed feedback about their energy use; supplying energy-efficiency education and tips; rewarding households for reducing their energy use; comparing households to their peers; and establishing games, tournaments, and competitions. BB programs often target multiple energy end uses and encourage energy savings, demand savings, or both. Savings from BB programs are usually a small percentage of energy use, typically less than 5%.

    Air pollution, land price development and assessment of immission control needs in urban development plans. The impact of immission pollution by sulphur dioxide and dust precipitation on property prices in residential areas of Dortmund and Duisburg. The focus of this thesis is on studying the links between property prices and air pollution. The ground rent theory which goes back to the 16th century provides the theoretical basis for this work. RICARDO put forward the theory, that air may, under certain circumstances, - as for instance different local air pollution levels or sensitivity of locals to air quality -, which did not apply 200 years ago actually produce rent. These circumstances do indeed apply widely today - different air pollution levels in urban areas are just a case in point. Various empiricial studies in the U.S. proved that air pollution with different substances does actually influence the value of property. The ground rent influenced by air pollution is called ''air rent''. This study contains empirical studies on the influence of air pollution by sulphur dioxide SO 2 and dust precipitation on general property prices in residential areas of Dortmund between 1979 and 1989 and Duisburg between 1981 and 1989.

    Heinemeyer, Ute

    2009-07-20

    The aim of this work was to establish the anisotropic dielectric function of organic thin films on silicon covered with native oxide and to study their optical properties during film growth. While the work focuses mainly on the optical properties of Diindenoperylene (DIP) films, also the optical response of Pentacene (PEN) films during growth is studied for comparison. Spectroscopic ellipsometry and differential reflectance spectroscopy are used to determine the dielectric function of the films ex-situ and in-situ, i.e. in air and in ultrahigh vacuum. Additionally, Raman- and fluorescence spectroscopy is utilized to characterize the DIP films serving also as a basis for spatially resolved optical measurements beyond the diffraction limit. Furthermore, X-ray reflectometry and atomic force microscopy are used to determine important structural and morphological film properties. The absorption spectrum of DIP in solution serves as a monomer reference. The observed vibronic progression of the HOMO-LUMO transition allows the determination of the Huang-Rhys parameter experimentally, which is a measure of the electronic vibrational coupling. The corresponding breathing modes are measured by Raman spectroscopy. The optical properties of DIP films on native oxide show significant differences compared to the monomer spectrum due to intermolecular interactions. First of all, the thin film spectra are highly anisotropic due to the structural order of the films. Furthermore the Frenkel exciton transfer is studied and the energy difference between Frenkel and charge transfer excitons is determined. Real-time measurements reveal optical differences between interfacial or surface molecules and bulk molecules that play an important role for device applications. They are not only performed for DIP films but also for PEN films. While for DIP films on glass the appearance of a new mode is visible, the spectra of PEN show a pronounced energy red-shift during growth. It is shown how the

  9. Function Modelling Of The Market And Assessing The Degree Of Similarity Between Real Properties - Dependent Or Independent Procedures In The Process Of Office Property Valuation

    Directory of Open Access Journals (Sweden)

    Barańska Anna

    2015-09-01

    Full Text Available Referring to the developed and presented in previous publications (e.g. Barańska 2011 two-stage algorithm for real estate valuation, this article addresses the problem of the relationship between the two stages of the algorithm. An essential part of the first stage is the multi-dimensional function modelling of the real estate market. As a result of selecting the model best fitted to the market data, in which the dependent variable is always the price of a real property, a set of market attributes is obtained, which in this model are considered to be price-determining. In the second stage, from the collection of real estate which served as a database in the process of estimating model parameters, the selected objects are those which are most similar to the one subject to valuation and form the basis for predicting the final value of the property being valued. Assessing the degree of similarity between real properties can be carried out based on the full spectrum of real estate attributes that potentially affect their value and which it is possible to gather information about, or only on the basis of those attributes which were considered to be price-determining in function modelling. It can also be performed by various methods. This article has examined the effect of various approaches on the final value of the property obtained using the two-stage prediction. In order fulfill the study aim precisely as possible, the results of each calculation step of the algorithm have been investigated in detail. Each of them points to the independence of the two procedures.

    Full Text Available The purpose of this study is to determine the optimal capital structure of property, real estate, and construction companies listed in Indonesia Stock Exchange. The motivation of this study is due to the current research results are still not able to answer whether the optimal capital structure exists. Based on trade-off theory, the optimal capital structure occurs when a company has a minimum capital cost. However,  it is not explained how much capital structure needed to achieve the company maximum value. In addition, this sample business sector is chosen because there are a numeours firms with an adequate long-term debt which make it possible to examine their capital structure. The method used are the nonlinear regression and Monte Carlo simulation method. These methods were chosen because the formulation of optimal capital structure is arguably complex. There are 47 samples from all property, real estate, and construction companies. The data set covered 11 years ie (2000-2010. The results showed that the optimal capital structure of properties, real estate and construction companies which are measured by the ratio between the long-term debt and equity is 0.99. Most companies of these sectors have not reached the optimal capital structure yet because the average results from these companies are 0.31.

  19. Modelling and forecasting Turkish residential electricity demand

    International Nuclear Information System (INIS)

    Dilaver, Zafer; Hunt, Lester C

    2011-01-01

    This research investigates the relationship between Turkish residential electricity consumption, household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008. Household total final consumption expenditure, real energy prices and an underlying energy demand trend are found to be important drivers of Turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0.38 and 1.57, respectively, and the estimated short run and long run price elasticities being -0.09 and -0.38, respectively. Moreover, the estimated underlying energy demand trend, (which, as far as is known, has not been investigated before for the Turkish residential sector) should be of some benefit to Turkish decision makers in terms of energy planning. It provides information about the impact of past policies, the influence of technical progress, the impacts of changes in consumer behaviour and the effects of changes in economic structure. Furthermore, based on the estimated equation, and different forecast assumptions, it is predicted that Turkish residential electricity demand will be somewhere between 48 and 80 TWh by 2020 compared to 40 TWh in 2008. - Research highlights: → Estimated short run and long run expenditure elasticities of 0.38 and 1.57, respectively. → Estimated short run and long run price elasticities of -0.09 and -0.38, respectively. → Estimated UEDT has increasing (i.e. energy using) and decreasing (i.e. energy saving) periods. → Predicted Turkish residential electricity demand between 48 and 80 TWh in 2020.

    2016-01-01

    Full Text Available The aim of this paper is to review the property types diversification strategy of Malaysian REITs. Previous study has found that Malaysian REITs received poor response form investors both local and international. Furthermore, the underperformance of Malaysian REITs was linked to the characteristics of REITs’ property types and REITs’ portfolio influenced its financial performance. The lack of local study on both of these determinants of influence on performance of Malaysian REITs is a research gap, which needs to be explored that can provide more insight of it. This study showed that the property types such as office space, commercial lot, industrial, hotel and specialized property type are the important determinants, which can influence the performance of REITs. The study comprised of REITs data from 2010 until 2014, and through Multiple Regression Analysis (MRA reveals there is little influence of property types diversification strategy toward Malaysian REITs’ performance. Nevertheless, by employ correlation analysis between each of the five property types with expected return and dividend yield, this study shows Malaysian REITs’ performance of dividend yield(DY has a positive correlation value with commercial lot property type and Malaysian REITs’ performance of expected return(ER have a highest positive correlation value with industrial property types. Also, this study suggests that property type diversification play a significant role in Malaysia REITs. Other determinants such as location of property, market capitalization and REITs’ quality of advisory style that might influence the diversification strategy and financial performance of Malaysian REITs.

  9. The structure and properties of vacancies in Si nano-crystals calculated by real space pseudopotential methods

    International Nuclear Information System (INIS)

    Beckman, S.P.; Chelikowsky, James R.

    2007-01-01

    The structure and properties of vacancies in a 2 nm Si nano-crystal are studied using a real space density functional theory/pseudopotential method. It is observed that a vacancy's electronic properties and energy of formation are directly related to the local symmetry of the vacancy site. The formation energy for vacancies and Frenkel pair are calculated. It is found that both defects have lower energy in smaller crystals. In a 2 nm nano-crystal the energy to form a Frenkel pair is 1.7 eV and the energy to form a vacancy is no larger than 2.3 eV. The energy barrier for vacancy diffusion is examined via a nudged elastic band algorithm

  11. Guidelines for residential commissioning

    Energy Technology Data Exchange (ETDEWEB)

    Wray, Craig P.; Walker, Iain S.; Sherman, Max H.

    2003-01-31

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify problems or to correct them. Residential commissioning is a solution to this problem. This guide is the culmination of a 30-month project that began in September 1999. The ultimate objective of the project is to increase the number of houses that undergo commissioning, which will improve the quality, comfort, and safety of homes for California citizens. The project goal is to lay the groundwork for a residential commissioning industry in California focused on end-use energy and non-energy issues. As such, we intend this guide to be a beginning and not an end. Our intent is that the guide will lead to the programmatic integration of commissioning with other building industry processes, which in turn will provide more value to a single site visit for people such as home energy auditors and raters, home inspectors, and building performance contractors. Project work to support the development of this guide includes: a literature review and annotated bibliography, which facilitates access to 469 documents related to residential commissioning published over the past 20 years (Wray et al. 2000), an analysis of the potential benefits one can realistically expect from commissioning new and existing California houses (Matson et al. 2002), and an assessment of 107 diagnostic tools for evaluating residential commissioning metrics (Wray et al. 2002). In this guide, we describe the issues that non-experts should consider in developing a commissioning program to achieve the benefits we have identified. We do this by providing specific recommendations about: how to structure the commissioning process, which diagnostics to use, and how to use them to commission new and existing houses. Using examples, we also demonstrate the potential benefits of applying the recommended whole-house commissioning approach to

  20. Integrated automated nanomanipulation and real-time cellular surface imaging for mechanical properties characterization

    Science.gov (United States)

    Eslami, Sohrab; Zareian, Ramin; Jalili, Nader

    2012-10-01

    Surface microscopy of individual biological cells is essential for determining the patterns of cell migration to study the tumor formation or metastasis. This paper presents a correlated and effective theoretical and experimental technique to automatically address the biophysical and mechanical properties and acquire live images of biological cells which are of interest in studying cancer. In the theoretical part, a distributed-parameters model as the comprehensive representation of the microcantilever is presented along with a model of the contact force as a function of the indentation depth and mechanical properties of the biological sample. Analysis of the transfer function of the whole system in the frequency domain is carried out to characterize the stiffness and damping coefficients of the sample. In the experimental section, unlike the conventional atomic force microscope techniques basically using the laser for determining the deflection of microcantilever's tip, a piezoresistive microcantilever serving as a force sensor is implemented to produce the appropriate voltage and measure the deflection of the microcantilever. A micromanipulator robotic system is integrated with the MATLAB® and programmed in such a way to automatically control the microcantilever mounted on the tip of the micromanipulator to achieve the topography of biological samples including the human corneal cells. For this purpose, the human primary corneal fibroblasts are extracted and adhered on a sterilized culture dish and prepared to attain their topographical image. The proposed methodology herein allows an approach to obtain 2D quality images of cells being comparatively cost effective and extendable to obtain 3D images of individual cells. The characterized mechanical properties of the human corneal cell are furthermore established by comparing and validating the phase shift of the theoretical and experimental results of the frequency response.

  1. Total Cross Sections and Event Properties from Real to Virtual Photons

    International Nuclear Information System (INIS)

    Friberg, Christer; Sjoestrand, Torbjoern

    2000-01-01

    A model for total cross sections with virtual photons is presented. In particular gamma*-p and gamma*-gamma* cross sections are considered. Our approach extends on a model for photoproduction, where the total cross section is subdivided into three distinct event classes: direct, VMD and anomalous. With increasing photon virtuality, the latter two decrease in importance. Instead Deep Inelastic Scattering dominates, with the direct class being the O(alpha s ) correction thereof. Hence, the model provides a smooth transition between the two regions. By the breakdown into different event classes, one may aim for a complete picture of all event properties. (author)

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Toledo and Ciudad Real of the Comunidad Autonoma de Castilla-La Mancha.

    2013-01-30

    Real-time monitoring techniques based on an NIR spectrometer and a thermal effusivity sensor for lubrication properties of magnesium stearate (Mg-St) are proposed. The lubrication properties of Mg-St are defined by its concentration distribution and flatting state in a mixture. The concentration distribution of Mg-St significantly affects the absorbance in the NIR wavelength region between 1128 nm and 1240 nm. Thus, the absorbance area in this region after baseline correction was selected as a monitoring index (MI). In laboratory-scale experiments, the difference of Mg-St concentration distribution could be detected by the proposed MI with high sensitivity. In addition, experimental results using spherical mannitol granules confirmed that the changes of the flatting state of Mg-St could also be detected by the proposed MI. Similar experiments with spherical mannitol granules and the thermal effusivity sensor confirmed that effusivity could also be used to detect the changes of the flatting state of Mg-St. The applicability of these monitoring techniques was verified using a 2000 L commercial-scale blender equipped with the NIR spectrometer and the thermal effusivity sensor. The results showed that both lubrication properties could be monitored by the proposed MI, and that the flatting state of Mg-St could be monitored more sensitively by using the effusivity.

    2015-01-01

    While researchers are increasingly re-conceptualizing international migration, far less attention has been devoted to re-thinking short-distance residential mobility and immobility. In this paper we harness the life course approach to propose a new conceptual framework for residential mobility research. We contend that residential mobility and immobility should be re-conceptualized as relational practices that link lives through time and space while connecting people to structural conditions. Re-thinking and re-assessing residential mobility by exploiting new developments in longitudinal analysis will allow geographers to understand, critique and address pressing societal challenges.

  6. Perspective: Web-based machine learning models for real-time screening of thermoelectric materials properties

    Directory of Open Access Journals (Sweden)

    Michael W. Gaultois

    2016-05-01

    Full Text Available The experimental search for new thermoelectric materials remains largely confined to a limited set of successful chemical and structural families, such as chalcogenides, skutterudites, and Zintl phases. In principle, computational tools such as density functional theory (DFT offer the possibility of rationally guiding experimental synthesis efforts toward very different chemistries. However, in practice, predicting thermoelectric properties from first principles remains a challenging endeavor [J. Carrete et al., Phys. Rev. X 4, 011019 (2014], and experimental researchers generally do not directly use computation to drive their own synthesis efforts. To bridge this practical gap between experimental needs and computational tools, we report an open machine learning-based recommendation engine (http://thermoelectrics.citrination.com for materials researchers that suggests promising new thermoelectric compositions based on pre-screening about 25 000 known materials and also evaluates the feasibility of user-designed compounds. We show this engine can identify interesting chemistries very different from known thermoelectrics. Specifically, we describe the experimental characterization of one example set of compounds derived from our engine, RE12Co5Bi (RE = Gd, Er, which exhibits surprising thermoelectric performance given its unprecedentedly high loading with metallic d and f block elements and warrants further investigation as a new thermoelectric material platform. We show that our engine predicts this family of materials to have low thermal and high electrical conductivities, but modest Seebeck coefficient, all of which are confirmed experimentally. We note that the engine also predicts materials that may simultaneously optimize all three properties entering into zT; we selected RE12Co5Bi for this study due to its interesting chemical composition and known facile synthesis.

  7. Real time transverse-force sensor based on polarization properties of fiber Bragg grating and cross-sensitivity compensation

    International Nuclear Information System (INIS)

    Su, Yang; Zhu, Yong; Zhang, Baofu; Peng, Hui; Ye, Zhenxing

    2013-01-01

    We present a new method for real-time transverse force sensor based on the measurement of the polarization properties of a uniform fiber Bragg grating (FBG) written into standard single mode fiber. Unlike the usual spectral analysis of FBG sensors, we demonstrate here that the amplitude of the first Stokes parameters of a uniform FBG in transmission can be used to obtain transverse force value. The influences of incident angle of linear polarized light launched into FBG on sensor performance are analyzed. Experimental results measured by means of a tunable laser source and a polarimeter are presented. We also propose a kind of grating structure with triangular-shaped transmission spectrum to reduce the influences of cross-sensitivity. The compensation effect can satisfy the requirements of the practical application with optimized grating parameters. (paper)

    2017-05-01

    Flow ball devices have been used as teaching tools to provide visual real-time feedback of airflow during singing. This study aims at exploring static back pressure and ball height as function of flow for two devices, marketed as flow ball and floating ball game. This is a comparative descriptive study. A flow-driven vocal tract simulator was used to investigate the aerodynamic properties of these two devices, testing them for four different ball sizes. The flow range investigated was between 0 and 0.5 L/s. Audio, flow, pressure, and ball height were recorded. The flow pressure profiles for both tested devices were similar to those observed in previous studies on narrow tubes. For lifting the ball, both devices had a flow and a pressure threshold. The tested floating ball game required considerably higher back pressure for a given flow as compared with the flow ball. Both tested devices have similar effects on back pressure as straws of 3.7 and 3.0 mm in diameter for the flow ball and the floating ball game, respectively. One might argue that both devices could be used as tools for practicing semi-occluded vocal tract exercises, with the additional benefit of providing real-time visual feedback of airflow during phonation. The flow threshold, combined with the flow feedback, would increase awareness of flow, rather than of pressure, during exercises using a flow ball device. Published by Elsevier Inc.

  9. ASHRAE and residential ventilation

    Energy Technology Data Exchange (ETDEWEB)

    Sherman, Max H.

    2003-10-01

    In the last quarter of a century, the western world has become increasingly aware of environmental threats to health and safety. During this period, people psychologically retreated away from outdoors hazards such as pesticides, smog, lead, oil spills, and dioxin to the seeming security of their homes. However, the indoor environment may not be healthier than the outdoor environment, as has become more apparent over the past few years with issues such as mold, formaldehyde, and sick-building syndrome. While the built human environment has changed substantially over the past 10,000 years, human biology has not; poor indoor air quality creates health risks and can be uncomfortable. The human race has found, over time, that it is essential to manage the indoor environments of their homes. ASHRAE has long been in the business of ventilation, but most of the focus of that effort has been in the area of commercial and institutional buildings. Residential ventilation was traditionally not a major concern because it was felt that, between operable windows and envelope leakage, people were getting enough outside air in their homes. In the quarter of a century since the first oil shock, houses have gotten much more energy efficient. At the same time, the kinds of materials and functions in houses changed in character in response to people's needs. People became more environmentally conscious and aware not only about the resources they were consuming but about the environment in which they lived. All of these factors contributed to an increasing level of public concern about residential indoor air quality and ventilation. Where once there was an easy feeling about the residential indoor environment, there is now a desire to define levels of acceptability and performance. Many institutions--both public and private--have interests in Indoor Air Quality (IAQ), but ASHRAE, as the professional society that has had ventilation as part of its mission for over 100 years, is the

    Residential air conditioning (AC) represents a challenging load for many electric utilities with poor load factors. Mechanical precooling improves the load factor by shifting cooling operation from on-peak to off-peak hours. This provides benefits to utilities and the electricity grid, as well as to occupants who can take advantage of time-of-use (TOU) electricity rates. Performance benefits stem from reduced compressor cycling, and shifting condensing unit operation to earlier periods of the day when outdoor temperatures are more favorable to operational efficiency. Finding solutions that save energy and reduce demand on the electricity grid is an important national objective and supports key Building America goals. The Alliance for Residential Building Innovation team evaluated mechanical AC precooling strategies in homes throughout the United States. EnergyPlus modeling was used to evaluate two homes with different performance characteristics in seven climates. Results are applicable to new construction homes and most existing homes built in the last 10 years, as well as fairly efficient retrofitted homes. A successful off-peak AC strategy offers the potential for increased efficiency and improved occupant comfort, and promotes a more reliable and robust electricity grid. Demand response capabilities and further integration with photovoltaic TOU generation patterns provide additional opportunities to flatten loads and optimize grid impacts.

    The real-time estimation of the wide-lane and narrow-lane Uncalibrated Phase Delay (UPD) of satellites is realized by real-time data received from regional reference station networks; The properties of the real-time UPD product and its influence on real-time precise point positioning ambiguity resolution (RTPPP-AR) are experimentally analyzed according to real-time data obtained from the regional Continuously Operating Reference Stations (CORS) network located in Tianjin, Shanghai, Hong Kong, etc. The results show that the real-time wide-lane and narrow-lane UPD products differ significantly from each other in time-domain characteristics; the wide-lane UPDs have daily stability, with a change rate of less than 0.1 cycle/day, while the narrow-lane UPDs have short-term stability, with significant change in one day. The UPD products generated by different regional networks have obvious spatial characteristics, thus significantly influencing RTPPP-AR: the adoption of real-time UPD products employing the sparse stations in the regional network for estimation is favorable for improving the regional RTPPP-AR up to 99%; the real-time UPD products of different regional networks slightly influence PPP-AR positioning accuracy. After ambiguities are successfully fixed, the real-time dynamic RTPPP-AR positioning accuracy is better than 3 cm in the plane and 8 cm in the upward direction.

  12. The Valuation of Hope Value for Real Estate Development

    Directory of Open Access Journals (Sweden)

    Renigier-Biłozor Małgorzata

    2017-06-01

    Full Text Available In the valuation of a property subject to development, the valuer may consider the potential aspect of the value of both land to be improved and a building to be refurbished. These kinds of valuations are complex, especially when a prudent assessment of value is required. In general terms, all properties may have potential development which, in some cases, can be termed “hope”. In particular, uncertainty regarding the change in the legal framework may create expectations as to the uncertain variation of property value in the future. In these cases, it may be necessary to deal with hope value or future value, trying to reach the value of a property subjected to uncertain changes. Hope value is the difference between the existing use value and the price that the market might pay for future transformation. The main aim of the paper is the elaboration of a methodology to determine the hope value. In this work, a real option model for the valuation of hope value in the real estate market will be applied to a small sample of residential properties located in Olsztyn that are subject to possible transformation. The possibility of a transformation may create expectations and may influence the value of the property. Although the applications of these methods to real estate valuation are fairly recent, the International Valuation Standards have included real option theory in the income approach as a valuation method since 2011.

  13. Appraisal of the Fischer-DiPasquale-Wheaton (FDW real estate model and development of an integrated property and asset market model

    Directory of Open Access Journals (Sweden)

    H Du Toit

    2004-04-01

    Full Text Available This paper provides a concise overview of the development of an integrated property and asset market model (IPAMM for South African property markets, utilising the Pretoria office market as case study. The IPAMM simulates the interrelationships between property and asset markets in a diagrammatic quadrant model configuration. The Fischer-DiPasquale-Wheaton (FDW real estate model, arguably the most advanced diagrammatic quadrant real estate model available at present, served as basis for the development of IPAMM. IPAMM is essentially a regression model based on a system of stochastic equations that captures the interrelationships between property and asset markets. The model advances beyond mere conceptualisation of these relationships to a quantified interpretation and application of the theoretical premises that represent the micro-foundations of economic behaviour in property and asset markets.

    Full Text Available Techniques for residential energy monitoring are an emerging field that is currently drawing significant attention. This paper is a description of the current efforts to monitor and compare the performance of three solar powered homes built at Missouri University of Science and Technology. The homes are outfitted with an array of sensors and a data logger system to measure and record electricity production, system energy use, internal home temperature and humidity, hot water production, and exterior ambient conditions the houses are experiencing. Data is being collected to measure the performance of the houses, compare to energy modeling programs, design and develop cost effective sensor systems for energy monitoring, and produce a cost effective home control system.

  16. College residential sleep environment.

    2013-12-01

    College students regularly report increased sleep disturbances as well as concomitant reductions in performance (e.g., academic grades) upon entering college. Sleep hygiene refers to healthy sleep practices that are commonly used as first interventions in sleep disturbances. One widely used practice of this sort involves arranging the sleep environment to minimize disturbances from excessive noise and light at bedtime. Communal sleep situations such as those in college residence halls do not easily support this intervention. Following several focus groups, a questionnaire was designed to gather self-reported information on sleep disturbances in a college population. The present study used The Young Adult Sleep Environment Inventory (YASEI) and sleep logs to investigate the sleep environment of college students living in residential halls. A summary of responses indicated that noise and light are significant sleep disturbances in these environments. Recommendations are presented related to these findings.

  17. MATHEMATICAL JUSTIFICATION OF RESERACH METODOLOGY OF FUZZY SET PROPERTIES OF THE GESKE MODEL AND ITS MODIFICAIONS TO REAL OPTIONS

    Directory of Open Access Journals (Sweden)

    Baranov A. O.

    2016-06-01

    Full Text Available The purpose of this study is to adapt methods of fuzzy sets to analyze the effectiveness of multistage investment projects. The problem solved by the study is as follows. Some innovative projects are characterized by the lack of profitability in the early stages of implementation and high risk associated with high uncertainty of assessment of expected future cash flows generated by the project. In this situation, the use of standard methods of analysis of economic efficiency of investment projects in high-tech industries, does not provide a comprehensive assessment of the appropriateness of investing, as well as to quantify the accuracy of the dynamics of the projected figures. All this requires the development of theory and methods of analysis of economic efficiency of innovation. Application of real options, as well as the fuzzy sets is, in our view, the direction of improving these methods. The fuzzy random pairs approach is developed in order to study fuzzy set properties of random pointwise set mappings. The articles proposes generalization of the fuzzy random pairs approach for research of stochastic processes. The generalization is initiated by an approach to exploration of uncertainty in research project supported with an RFBR grant no. 15-06-06914, which is based on application of the Geske model modification. Mathematical description of the generalization is carried out for an example of a real venture-backed investment project aimed at organization of methyl chloride to ethylene processing. The generalization essence is in the following: 1 time variable t in a random process ξ ( t is replaced with a random value u , distributed uniformly within a segment [0; T ], which turns the process ξ ( t into a bidimensional random value V = u ,ξ( 0;( u , defined on [ T ]× R ; 2 the random value V value is translated into a random pointwise set mapping using the interval translation; 3 in order to translate the random pointwise set mapping

  19. Looking For Value in All The Wrong Places. Toward Expanded Consideration of Green and High Performance Attributes in Non-residential Property Appraisals in the United States

    2015-10-21

    Large numbers of commercial buildings have sought to improve their energy and environmental performance, with half of all leasable U.S. offices now designated at some level of “green”. All proper/es fall somewhere on the green/high-­performance spectrum (above and below average) whether or not they bear a formal label or ra/ng.1 Variations in the level of performance can either positively or negatively influence value. This component of value can be shaped by many factors, from utility costs to tenant/owner preferences that translate into income (rent levels, vacancy rates, lease-­up /mes, etc.). Occupant perceptions of indoor environmental quality are another potential influence on value. While there has been little uptake of this thinking by practicing appraisers, the increased prevalence of green/HP practices combined with concerns about appraiser competency are compelling the industry to adapt their traditional techniques to this new driver of value. However, the overly narrow focus of policymakers on appraisal of labeled or rated exemplary buildings (e.g., LEED or ENERGY STAR Certified) represents a significant missed opportunity. Any level of green or energy performance can in fact influence value, including below-­average performance (a.k.a. “brown discount”), irrespec/ve of whether or not the building has been formally rated. Another surmountable challenge is the limitations to non-­appraisers’ understanding of the appraisal process (and constraints therein). A crucial byproduct of this is unrealistic expectations of what appraisers can and will do in the marketplace. This report identifies opportunities for catalyzing improvement of the green/HP appraisal process, which apply to all involved actors—from owner, report-­ordering client, the appraiser, and the appraisal reviewer—and fostering more demand for appraisals that recognize green/HP property attributes. The intended audience is primarily the public policy community and other

    There are multiple ways for a homeowner to obtain the electricity generating and savings benefits offered by a photovoltaic (PV) system. These include purchasing a PV system through various financing mechanisms, or by leasing the PV system from a third party with multiple options that may include purchase, lease renewal or PV system removal. The different ownership options available to homeowners presents a challenge to appraisal and real estate professionals during a home sale or refinance in terms of how to develop a value that is reflective of the PV systems operational characteristics, local market conditions, and lender and underwriter requirements. This paper presents these many PV system ownership options with a discussion of what considerations an appraiser must make when developing the contributory value of a PV system to a residential property.

  9. Financing Non-Residential Photovoltaic Projects: Options and Implications

    Energy Technology Data Exchange (ETDEWEB)

    Bolinger, Mark

    2009-01-09

    Installations of grid-connected photovoltaic (PV) systems in the United States have increased dramatically in recent years, growing from less than 20 MW in 2000 to nearly 500 MW at the end of 2007, a compound average annual growth rate of 59%. Of particular note is the increasing contribution of 'non-residential' grid-connected PV systems--defined here as those systems installed on the customer (rather than utility) side of the meter at commercial, institutional, non-profit, or governmental properties--to the overall growth trend. Although there is some uncertainty in the numbers, non-residential PV capacity grew from less than half of aggregate annual capacity installations in 2000-2002 to nearly two-thirds in 2007. This relative growth trend is expected to have continued through 2008. The non-residential sector's commanding lead in terms of installed capacity in recent years primarily reflects two important differences between the non-residential and residential markets: (1) the greater federal 'Tax Benefits'--including the 30% investment tax credit (ITC) and accelerated tax depreciation--provided to commercial (relative to residential) PV systems, at least historically (this relative tax advantage has largely disappeared starting in 2009) and (2) larger non-residential project size. These two attributes have attracted to the market a number of institutional investors (referred to in this report as 'Tax Investors') seeking to invest in PV projects primarily to capture their Tax Benefits. The presence of these Tax Investors, in turn, has fostered a variety of innovative approaches to financing non-residential PV systems. This financial innovation--which is the topic of this report--has helped to overcome some of the largest barriers to the adoption of non-residential PV, and is therefore partly responsible (along with the policy changes that have driven this innovation) for the rapid growth in the market seen in recent years

  10. Problems Related to the Abolition of Divided Real Estate Ownership

    Full Text Available Legal relationship between apartment owners in residential buildings and the land owners, that is, divided real estate ownership, was created in the Republic of Latvia in 1990, within the framework of the Land Reform, restoring property rights of the former owners or their heirs or privatising apartments in multi-apartment residential buildings. The existence of such legal relationship created different lease problems and restrictions on the property rights to the owners of both the building and the land. To abolish the legal relationship related to divided real estate ownership, the Ministry of Justice of the Republic of Latvia has developed a draft law Regarding the Abolition of Mandatory Divided Real Estate Ownership in Multi-Apartment Buildings (hereinafter referred to as Draft Law. Unfortunately, in the opinion of authors of this article, there are serious shortcomings to the Draft Law which must be corrected. The aim of the research is to identify the problematic issues by selecting and analysing the legislation on the abolition of the divided real estate ownership, which is related to the calculation of redemption price, payment method and consequences of non-payment, which are not regulated by the new Draft Law. The article reflects research on the determination and calculation of redemption price reglamented by the Draft Law and also analyses the Law of December 8, 1938, On the Abolition of Divided Real Estate Ownership and its practical implementation, which may significantly influence the redemption price and the method of its calculation; however, the mentioned law has been disregarded in developing the Draft Law. Thus the research has both theoretical and practical significance. For the research purposes general research methods, such as historical, analytical, inductive, deductive, logical-constructive and descriptive methods, are used. For the interpretation of legislation norms, grammatical, systemic, teleological and historical

  11. Thermal Profiling of Residential Energy Use

    Albert, A; Rajagopal, R

    2015-03-01

    This work describes a methodology for informing targeted demand-response (DR) and marketing programs that focus on the temperature-sensitive part of residential electricity demand. Our methodology uses data that is becoming readily available at utility companies-hourly energy consumption readings collected from "smart" electricity meters, as well as hourly temperature readings. To decompose individual consumption into a thermal-sensitive part and a base load (non-thermally-sensitive), we propose a model of temperature response that is based on thermal regimes, i.e., unobserved decisions of consumers to use their heating or cooling appliances. We use this model to extract useful benchmarks that compose thermal profiles of individual users, i.e., terse characterizations of the statistics of these users' temperature-sensitive consumption. We present example profiles generated using our model on real consumers, and show its performance on a large sample of residential users. This knowledge may, in turn, inform the DR program by allowing scarce operational and marketing budgets to be spent on the right users-those whose influencing will yield highest energy reductions-at the right time. We show that such segmentation and targeting of users may offer savings exceeding 100% of a random strategy.

    Full Text Available An investment opportunity in the real state market can be compared with an option and, because of this analogy, we can make use of the real options theory to determinate not only the best timing to begin a new property development, but also to determine the optimal density to develop in a specific property. To investigate these two main decisions, we are going to base our research on the model developed by Williams (1991 and extend it in a way to include taxes and a discount in the net cash inflow caused by the times spent in the construction process. An empirical analysis of the of the residential real estate market in the city of Rio de Janeiro is going to be developed in a way to verify the compatibility of the theoretical model developed here according to the reality of this market. We found that the extensions proposed to the basic model of Williams (1991 had significant effects in the theoretical model. We could also confirm empirically that the theoretical results are compatible to the reality of this market.

    2014-05-01

    Full Text Available Over the post-socialist period, residential mobility processes were very intense and took place on large areas. Flow intensity led to the emergence of new spatial and functional realities and created new relationships within the affected areas. During all this period, Bucharest’s metropolitan area was shaped by the spatial mobility of the city dwellers, as well as by the change of their social and residential aspirations. The majority of those who were registered as movers in Bucharest were actually residents of Bucharest (they only changed their domicile and the share of people coming to the city from elsewhere has increased constantly over the last decade. Except for the early 1990s, a period when residential legal status was pending clarification, migrations from peri-urban area, especially from Ilfov County, to Bucharest had a low intensity. Situation is quite different in terms of moving out of Bucharest, to the communes and towns of Ilfov County, located in close proximity, which have been continuously increasing values. The correlation between housing stock features (real estate supply and the demand of new dwellings (emphasized by the residential trajectories prove both that current mobility flows taking place at this time in Bucharest are segmented based on economic-spatial criteria and that Markov chains are functional.

    Green residential buildings are concerned by more and more people. However, the development of green residential buildings has been limited due to the single-standard requirements and lack of the multi-objective performance. At same time, the evaluation criteria system of green residential building is not comprehensive enough. So first of all, using SPSS software, residents questionnaire surveys are figured and found that the judge of experts and residents about the green elements is inconsistent, so the owners’ satisfaction is included in the post-evaluation criterial systems of green residential building from five aspects-the preliminary work of construction, construction process, economic, social benefits and owners satisfaction in Ningxia area, combined with expert interviews. Secondly, in the post-evaluation, it is difficult for many experts judgment matrix to meet the requirement of consistency, in this paper using MATLAB program, judgment matrix consistency is adjusted. And the weights of the criteria and sub-criteria and experts weights using group AHP method are determined. Finally, the grey clustering method is used to establish the post-evaluation model and the real case of Sai-shang project is carried out. It shows that the result obtained by using the improved criteria system and method in this paper is in a high degree of agreement with the actual result.

    Mass appraisal is widely considered an advanced frontier in the real estate valuation field. Performing mass appraisal entails the need to get access to base information conveyed by a large amount of transactions, such as prices and property features. Due to the lack of transparency of many Italian real estate market segments, our survey has been addressed to gather data from residential property advertisements. The dataset specifically focuses on property offer prices and dwelling energy efficiency. The latter refers to the label expressed and exhibited by the energy performance certificate. Moreover, data are georeferenced with the highest possible accuracy: at the neighborhood level for a 76.8% of cases, at street or building number level for the remaining 23.2%. Data are related to the analysis performed in Bonifaci and Copiello [1], about the relationship between house prices and building energy performance, that is to say, the willingness to pay in order to benefit from more efficient dwellings.

  4. Main challenges of residential areas

    2017-06-01

    Full Text Available The present article is a position paper aiming to initiate a professional debate related to the aspects related to the urban dysfunctions leading to the wear of the residential areas. The paper proposes a definition of the wear process, identify the main causes leading to its occurrence and propose a number of solutions to neutralise the dysfunctions. The three wearing phases of residential areas components are emphasized, exploring their lifecycle. In order to perform the study of urban wear, the status of the residential areas components can be established and monitored, and also the variables of the function that can mathematically model the specific wear process may be considered. The paper is considered a first step for the model adjustment, to be tested and validated in the following steps. Based on the mathematical method and model, there can be created, in a potential future research, the possibility of determining the precarity degree for residential areas/neighbourhoods and cities, by minimising the subjective component of the analyses preceding the decision for renovation or regeneration.

    Beauty, utility, durability - these are the features of good architecture and should also be the distinguishing qualities of every residential building. But do beauty and utility remain along with the passing of time? Performance characteristics are an indicator of both, the technical as well as aesthetic state of buildings. Aesthetic needs are in disagreement with the merciless aging process. The beauty of a city is formed not only by the original forms of new residential buildings, but also by existing tenement housing; thus preserving their aesthetics becomes a necessity. Time is continuously passing and along with it, aging intensifies. The aging process is a natural phenomenon for every material. The life expectancy of building materials is also limited. Along with the passing of time, the technical state of residential buildings continuously deteriorates. With the passing of time, the aesthetic values and preferences of users of flats change and the usability of the building decreases. The permanence of buildings, including residential buildings, is shaped not only by the forces of nature but also by activities of humans. A long lifespan is ensured by carrying out ongoing, systematic renovation-repair works. It is thanks to them that buildings derived from past centuries are still being used, and their market attractiveness is not decreasing.

  11. Modelling residential electricity demand in the GCC countries

    Atalla, Tarek N.; Hunt, Lester C.

    2016-01-01

    This paper aims at understanding the drivers of residential electricity demand in the Gulf Cooperation Council countries by applying the structural time series model. In addition to the economic variables of GDP and real electricity prices, the model accounts for population, weather, and a stochastic underlying energy demand trend as a proxy for efficiency and human behaviour. The resulting income and price elasticities are informative for policy makers given the paucity of previous estimates for a region with particular political structures and economies subject to large shocks. In particular, the estimates allow for a sound assessment of the impact of energy-related policies suggesting that if policy makers in the region wish to curtail future residential electricity consumption they would need to improve the efficiency of appliances and increase energy using awareness of consumers, possibly by education and marketing campaigns. Moreover, even if prices were raised the impact on curbing residential electricity growth in the region is likely to be very small given the low estimated price elasticities—unless, that is, prices were raised so high that expenditure on electricity becomes such a large proportion of income that the price elasticities increase (in absolute terms). - Highlights: • Residential electricity demand for Bahrain, Kuwait, Oman, and Saudi Arabia • Estimated residential electricity demand relationships using STSM/UEDT approach • LR income and price elasticities from 0.43 to 0.71 and − 0.16 to zero respectively • Impact CDD elasticities from 0.2 to 0.7 • Estimated UEDTs suggest exogenous electricity using behaviour.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve thin aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior ot its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Toledo and Ciudad Real of the Comunidad Autonoma de Castilla-La Mancha.

  13. Citizen Science as a Tool for Conservation in Residential Ecosystems

    Directory of Open Access Journals (Sweden)

    Caren B. Cooper

    2007-12-01

    Full Text Available Human activities, such as mining, forestry, and agriculture, strongly influence processes in natural systems. Because conservation has focused on managing and protecting wildlands, research has focused on understanding the indirect influence of these human activities on wildlands. Although a conservation focus on wildlands is critically important, the concept of residential area as an ecosystem is relatively new, and little is known about the potential of such areas to contribute to the conservation of biodiversity. As urban sprawl increases, it becomes urgent to construct a method to research and improve the impacts of management strategies for residential landscapes. If the cumulative activities of individual property owners could help conserve biodiversity, then residential matrix management could become a critical piece of the conservation puzzle. "Citizen science" is a method of integrating public outreach and scientific data collection locally, regionally, and across large geographic scales. By involving citizen participants directly in monitoring and active management of residential lands, citizen science can generate powerful matrix management efforts, defying the "tyranny of small decisions" and leading to positive, cumulative, and measurable impacts on biodiversity.

    Studies of environmental exposures and childhood leukemia studies do not usually account for residential mobility. Yet, in addition to being a potential risk factor, mobility can induce selection bias, confounding, or measurement error in such studies. Using data collected for California Powerline Study (CAPS), we attempt to disentangle the effect of mobility. We analyzed data from a population-based case-control study of childhood leukemia using cases who were born in California and diagnosed between 1988 and 2008 and birth certificate controls. We used stratified logistic regression, case-only analysis, and propensity-score adjustments to assess predictors of residential mobility between birth and diagnosis, and account for potential confounding due to residential mobility. Children who moved tended to be older, lived in housing other than single-family homes, had younger mothers and fewer siblings, and were of lower socioeconomic status. Odds ratios for leukemia among non-movers living mobility, including dwelling type, increased odds ratios for leukemia to 2.61 (95% CI: 1.76-3.86) for living mobility of childhood leukemia cases varied by several sociodemographic characteristics, but not by the distance to the nearest power line or calculated magnetic fields. Mobility appears to be an unlikely explanation for the associations observed between power lines exposure and childhood leukemia. Copyright © 2018 Elsevier Inc. All rights reserved.

    Full Text Available The article presents a comparative analysis of residential mortgages in Russia and the United States. The primary ways of mortgage refinancing are outlined. Predominance of the elements of two-level refinancing system of residential mortgage in Russia and the United States is shown. The activity of the Agency for Housing Mortgage Lending (AHML, the basic tool of the Russian government’s mortgage policy, is described in detail. In its objectives and functions the AHML is similar to the American mortgage agencies Ginnie Mae, Fannie Mae and Freddie Mac. Similarities were identified in the Russian and US residential mortgages in the pre-crisis period (high rates of mortgage growth, favourable economic conjuncture, low interest rates, large increase in house prices, speculative housing demand. During the mortgage crisis, the policies of the Russian and US governments and monetary authorities had also much in common (monetary policy easing, cheap central banks loans, extended facilities of mortgage refinancing on the part of state agencies, mortgage rescue scheme, social mortgage programs. But the scope of mortgage in Russia is enormously narrow as compared to the US mortgage. The most important reason for that - low incomes of the Russian population.

    We study the spectral polynomial of the Treibich-Verdier potential. Such spectral polynomial, which is a generalization of the classical Lamé polynomial, plays fundamental roles in both the finite-gap theory and the ODE theory of Heun's equation. In this paper, we prove that all the roots of such spectral polynomial are real and distinct under some assumptions. The proof uses the classical concept of Sturm sequence and isomonodromic theories. We also prove an analogous result for a polynomial associated with a generalized Lamé equation, where we apply a new approach based on the viewpoint of the monodromy data.

    2012-12-01

    Full Text Available The authors analyze the problem of implementation of principles of "green construction" in the Russian Federation. Despite the availability of the appropriate legislation in the field of environmental safety of construction, there are no legal, social, or economic incentives that may boost development of "green" technologies. Until recently, fundamentals of the state policy in the field of environmental protection of real estate development have not succeeded in motivating market players to implement advanced green technologies. However, recently, the government has begun motivating the construction industry towards the use of "green" technologies. The first activity is aimed at improving the legislation and updating the international voluntary certification according to BREAM and LEED standards. The result is the acceptance of the National Green Building Standard for real estate valuation that will open up new opportunities and prospects to the participants of the construction market. However, at the initial phase of implementation of "Fundamentals of the State Policy in the Field of Environmental Development of the Russian Federation", government authorities should provide their support to proponents of green buildings, including financial inflows.

  4. Microclimate Patterns of Residential Landscapes Across the US

    2014-12-01

    Urban development has altered the physical and biological properties of native ecosystems worldwide. Research on the environmental outcomes of development continues to increase in scope. Climate phenomena, such as the Urban Heat Island (UHI) and Park Cool Island (PCI), are frequently used to illustrate how cities and managed landscapes differ from rural lands. The UHI describes the disparity between urban and rural temperatures, and results from heat retention within the built environment. These effects may be locally mitigated by vegetation (PCI). While the UHI is a useful tool for examining cities on a large scale, the methods are often too coarse to describe what individuals experience. We wondered: What large-scale climate trends are detectable at microclimate levels? Are microclimate patterns within residential landscapes typical, or are they geographically variable? To investigate, we installed sensors to monitor the air temperature within yards (residential landscapes) and native landscapes of 6 US cities from unique climate zones; Los Angeles, Phoenix, Minneapolis, Baltimore, Miami, and Boston. We hypothesized that microclimate trends would be similar among cities, and that microclimate patterns would predominate over large-scale climate trends within residential landscapes, especially when atmospheric mixing is low. Air temperature data collected between Aug. 2012 and July 2014 reveal that residential landscapes experience significantly different temperatures than native landscapes (pre-sunrise). The differences drive cities toward similarity, despite the variability of climate zones. The 6 cities also experience similar patterns of diurnal temperature fluctuations. Daily temperature ranges in yards are significantly greater than in their corresponding native landscapes during cooler months (p microclimates in residential landscapes can create local heat sinks within the built environment that may alleviate UHI effects in some cities.

    2017-10-01

    Quality on indoor environment is among others also defined by an acoustic comfort and noise emissions. The indoor noise loading in the residential prefabricated buildings is specific problem related to structural design of these buildings. Problems with noise level of sanitary systems are mostly associated with hydraulic shock such as water distribution and sewage drainage. Another very common cause of excessive noise is also flushing the toilet or water fall on enamelled steel (bath or shower). This paper aims to analyse the acoustic properties in the residential prefabricated buildings. Sanitary core of the assessed apartment is in original condition without any alterations. The sanitary core is based on a formica (high-pressure laminate). The study discusses the maximum sound levels in the three assessed rooms for the three different noise sources. The values of maximum noise level are measured for the corridor, bedroom and living room. Sources of noise are common activities relating to the operation of sanitary core - the toilet flush in the toilet, falling water from the shower in the bathroom and the water falling on the bottom of the kitchen sink in the kitchen. Other sources of noise are eliminated or minimized during the experiment. The digital sound level meter Testo 815 is used for measurements. The measured values of maximum sound level LA,max [dB] are adjusted by the correction coefficient. The obtained values are compared with the hygienic limits for day and night period. Night hygienic limit (30 dB) is exceeded in all the rooms for all noise sources. This limit is exceeded from 17 to 73%. The values in the bedroom and the living room meet the daily hygienic limit (40 dB). The daily limit is exceeded only in the corridor. The highest values of noise are identified for the toilet flushing.

  6. Positional error in automated geocoding of residential addresses

    Talbot Thomas O

    2003-12-01

    Full Text Available Abstract Background Public health applications using geographic information system (GIS technology are steadily increasing. Many of these rely on the ability to locate where people live with respect to areas of exposure from environmental contaminants. Automated geocoding is a method used to assign geographic coordinates to an individual based on their street address. This method often relies on street centerline files as a geographic reference. Such a process introduces positional error in the geocoded point. Our study evaluated the positional error caused during automated geocoding of residential addresses and how this error varies between population densities. We also evaluated an alternative method of geocoding using residential property parcel data. Results Positional error was determined for 3,000 residential addresses using the distance between each geocoded point and its true location as determined with aerial imagery. Error was found to increase as population density decreased. In rural areas of an upstate New York study area, 95 percent of the addresses geocoded to within 2,872 m of their true location. Suburban areas revealed less error where 95 percent of the addresses geocoded to within 421 m. Urban areas demonstrated the least error where 95 percent of the addresses geocoded to within 152 m of their true location. As an alternative to using street centerline files for geocoding, we used residential property parcel points to locate the addresses. In the rural areas, 95 percent of the parcel points were within 195 m of the true location. In suburban areas, this distance was 39 m while in urban areas 95 percent of the parcel points were within 21 m of the true location. Conclusion Researchers need to determine if the level of error caused by a chosen method of geocoding may affect the results of their project. As an alternative method, property data can be used for geocoding addresses if the error caused by traditional methods is

    Full Text Available Green residential buildings (GRBs are one of the effective practices of energy saving and emission reduction in the construction industry. However, many real estate developers in China are less willing to develop GRBs, because of the factors affecting green residential building development (GRBD. In order to promote the sustainable development of GRBs in China, this paper, based on the perspective of real estate developers, identifies the influential and critical factors affecting GRBD, using the method of social network analysis (SNA. Firstly, 14 factors affecting GRBD are determined from 64 preliminary factors of three main elements, and the framework is established. Secondly, the relationships between the 14 factors are analyzed by SNA. Finally, four critical factors for GRBD, which are on the local economy development level, development strategy and innovation orientation, developer’s acknowledgement and positioning for GRBD, and experience and ability for GRBD, are identified by the social network centrality test. The findings illustrate the key issues that affect the development of GRBs, and provide references for policy making by the government and strategy formulation by real estate developers.

    For the formation of programs for housing construction and planning of capital investments, when developing the strategic planning companies by construction companies, the norms or calculated indicators of the duration of the construction of high-rise residential buildings and multifunctional complexes are mandatory. Determination of stable values of the parameters for the high-rise construction residential buildings provides an opportunity to establish a reasonable duration of construction at the planning and design stages of residential complexes, taking into account the influence of market conditions factors. The concept of the formation of enlarged models for the high-rise construction residential buildings is based on a real mapping in time and space of the most significant redistribution with their organizational and technological interconnection - the preparatory period, the underground part, the above-ground part, external engineering networks, landscaping. The total duration of the construction of a residential building, depending on the duration of each redistribution and the degree of their overlapping, can be determined by one of the proposed four options. At the same time, a unified approach to determining the overall duration of construction on the basis of the provisions of a streamlined construction organization with the testing of results on the example of high-rise residential buildings of the typical I-155B series was developed, and the coefficients for combining the work and the main redevelopment of the building were determined.

    Full Text Available Photovoltaics (PV in terms of installed capacity play a minor role in the portfolio of renewable energy sources (RES in Poland. However current market tendencies indicate that residential PV installations are gaining on popularity and may in future significantly contribute to covering national energy demand. This study investigates the potential impact of numerous residential PV installations on the shape and statistical properties of the polish energy demand curve. Analysis employed statistical data on mean household energy consumption in different districts, typical energy demand patterns and hourly values of irradiation for the year 2012. Obtained results indicate that there is a possibility to integrate in total as much as 300 000 residential PV installations (0.9 GW from which generated energy will be utilized by households within given district. Further analysis has shown that to some extent increasing number of residential PV decreases the value of energy demand coefficient of variation.

    2018-03-01

    Full Text Available Warangal city generates three hundred tons of garbage daily which is dropped into the Rampur dump yard by Warangal Municipal Corporation (WMC. Dumping of wastes will lead to the formation of leachate which in turn will cause environmental issues like soil and ground water contamination. Chemical analysis of leachate indicates that calcium, chloride, sodium and magnesium are the major ions, along with organic content. This leads to contamination of soil as well as ground water bodies. In this study, authors have attempted to know the behavior of soil under the influence of leachate. Contaminated specimens were prepared and tested for Atterberg limits, shear strength, swell potential and hydraulic conductivity of CH and SC which are present in the dumping yard. Index properties, hydraulic conductivity and swell potential decreased with increase in leachate concentration. Unconfined compressive strength also showed an increase. The decrease in hydraulic conductivity indicated the clogging of pores. In a nutshell, the present work deals with the impact of leachate on the index and engineering properties of CH and red soil.

    The goals of this scoping study are to identify research needed to develop improved ventilation standards for California's Title 24 Building Energy Efficiency Standards. The 2008 Title 24 Standards are the primary target for the outcome of this research, but this scoping study is not limited to that timeframe. We prepared this scoping study to provide the California Energy Commission with broad and flexible options for developing a research plan to advance the standards. This document presents the findings of a scoping study commissioned by the Public Interest Energy Research (PIER) program of the California Energy Commission to determine what research is necessary to develop new residential ventilation requirements for California. This study is one of three companion efforts needed to complete the job of determining the ventilation needs of California residences, determining the bases for setting residential ventilation requirements, and determining appropriate ventilation technologies to meet these needs and requirements in an energy efficient manner. Rather than providing research results, this scoping study identifies important research questions along with the level of effort necessary to address these questions and the costs, risks, and benefits of pursuing alternative research questions. In approaching these questions and corresponding levels of effort, feasibility and timing were important considerations. The Commission has specified Summer 2005 as the latest date for completing this research in time to update the 2008 version of California's Energy Code (Title 24).

    2016-01-01

    Full Text Available Key factors influencing electricity consumption in the residential sector in Poland have been identified. A fixed-effects model was used, which includes time effects, and a set of covariates, based on the model developed by Houthakker et al. This model estimates electricity demand by using lagged values of the dependent variable along with current and lagged values of electricity prices, and other variables that affect electricity demand such as: population, economic growth, income per capita, price of related goods, etc. The model has been identified according to the research results of the authors and those obtained by Bentzen and Engsted. The set of covariates was extended to the lagged electricity price given by a tariff (taken from two years previous to the time of interest and heating degree days index, a very important factor in European Union countries, where the climate is temperate. The authors propose four models of residential electricity demand, for which a confidence interval of 95% has been assumed. Estimation was based on Polish quarterly data for the years 2003-2013.

    Electrical energy consumption of the residential sector is a crucial area of research that has in the past primarily focused on increasing the efficiency of household devices such as water heaters, dishwashers, air conditioners, and clothes washer and dryer units. However, the focus of this research is shifting as objectives such as developing the smart grid and ensuring that the power system remains reliable come to the fore, along with the increasing need to reduce energy use and costs. Load research has started to focus on mechanisms to support the power system through demand reduction and/or reliability services. The power system relies on matching generation and load, and day-ahead and real-time energy markets capture most of this need. However, a separate set of grid services exist to address the discrepancies in load and generation arising from contingencies and operational mismatches, and to ensure that the transmission system is available for delivery of power from generation to load. Currently, these grid services are mostly provided by generation resources. The addition of renewable resources with their inherent variability can complicate the issue of power system reliability and lead to the increased need for grid services. Using load as a resource, through demand response programs, can fill the additional need for flexible resources and even reduce costly energy peaks. Loads have been shown to have response that is equal to or better than generation in some cases. Furthermore, price-incentivized demand response programs have been shown to reduce the peak energy requirements, thereby affecting the wholesale market efficiency and overall energy prices. The residential sector is not only the largest consumer of electrical energy in the United States, but also has the highest potential to provide demand reduction and power system support, as technological advancements in load control, sensor technologies, and communication are made.

    The study measured the indoor radon concentration in the dwellings of 3074 persons, selected randomly from the central population register of Finland. Alpha track detectors and two consecutive half year measuring periods were used. The national mean of indoor radon concentration for persons living in low-rise residential buildings as well as blocks of flats was 145 and 82 Bq/m 3 , respectively. The mean for the total population was 123 Bq/m 3 . Based on the decision of the Ministry of Social Affairs and Health in 1992, the indoor radon concentration should not exceed 400 Bq/m 3 in already existing houses, the target for new construction being less than 200 Bq/m 3 . According to the study, the percentage of the Finnish population living in houses with an indoor radon concentration exceeding 200, 400 and 800 Bq/m 3 was 12.3 %, 3.6 % and 1.0 %

  10. Norwegian residential electricity demand - a microeconomic assessment of the growth from 1976 to 1993

    International Nuclear Information System (INIS)

    Halvorsen, B.; Larsen, B.M.

    2001-01-01

    The Norwegian residential electricity consumption increased by an average of 3% annually during the period 1976-1993. Political signals indicate that the growth in Norwegian residential energy consumption should be reduced, and that it may be necessary to increase energy taxes. Based on data for the sample of households from the annual consumer expenditure survey, we study factors that are of importance explaining the growth in Norwegian residential electricity demand during this period. Nearly half of the growth is due to an increase in the number of households, while the rest reflects an increase in average consumption per household. The increase in average consumption per household is due to an increasing number of households possessing electric household appliances such as dryers and dishwashers, an increase in real disposable household income and in the floor space of dwellings.

    Full Text Available The subject of research. Given the steady demand for residential real estate, the low solvency of the population, and unbalanced development of individual segments of the regional housing market, competition issues and the mechanism of its operation, today is very relevant. Real estate is one of the components of the national economy because it carries more than half of total world wealth and its stable functioning is one of the most complex processes of market transformations occurring in the country. Active functioning property markets are a prerequisite for the sustainable development of cities and regions of the country. This development is the basis for the effective management of regional and implemented in the system of national governance and local governance. In modern terms, Ukraine is at the stage of the market system, one of which is real estate market. From the way, the subject of study is a competitive relationship, and especially their formation in the regional real estate market. Methodology. In order to carry out a thorough study, there was elaborated numerous scientific literature authored by leading scientists of Ukraine, Europe, and the former Soviet Union camp to define the concepts of “competition”, “regional market”, “real estate”, “residential property”. According to the research of current problems and competitive features in the structure of the real estate market on the basis of regional specificity, a logical systematization of these concepts is made. Results of the research allowed us to “carry” a clear parallel between the correlation of factors and competitive impact on the regional real estate market of the potential buyers, the developer and manufacturer of products directly to real estate as an object relationship. Practical implications. The article is to study the specific competitive position in the regional real estate market in Ukraine and also features of exposure to it by consumers

    2017-03-01

    In China, more than 80% electricity comes from coal which dominates the CO2 emissions. Residential electricity demand forecasting plays a significant role in electricity infrastructure planning and energy policy designing, but it is challenging to make an accurate forecast for developing countries. This paper forecasts the provincial residential electricity consumption of China in the 13th Five-Year-Plan (2016-2020) period using panel data. To overcome the limitations of widely used predication models with unreliably prior knowledge on function forms, a robust piecewise linear model in reduced form is utilized to capture the non-deterministic relationship between income and residential electricity consumption. The forecast results suggest that the growth rates of developed provinces will slow down, while the less developed will be still in fast growing. The national residential electricity demand will increase at 6.6% annually during 2016-2020, and populous provinces such as Guangdong will be the main contributors to the increments.

  18. Modeling radon transport in multistory residential buildings

    International Nuclear Information System (INIS)

    Persily, A.K.

    1993-01-01

    Radon concentrations have been studied extensively in single-family residential buildings, but relatively little work has been done in large buildings, including multistory residential buildings. The phenomena of radon transport in multistory residential buildings is made more complicated by the multizone nature of the airflow system and the numerous interzone airflow paths that must be characterized in such a system. This paper presents the results of a computer simulation of airflow and radon transport in a twelve-story residential building. Interzone airflow rates and radon concentrations were predicted using the multizone airflow and contaminant dispersal program (CON-TAM88). Limited simulations were conducted to study the influence of two different radon source terms, indoor-outdoor temperature difference and exterior wall leakage values on radon transport and radon concentration distributions

  19. Application of cavity ring-down spectroscopy for in situ, real-time measurements of properties of oceanographic interest in the surface ocean

    Huang, Kuan; Ma, Jian; Winkler, Renato; Dennis, Kate

    2015-04-01

    In situ, real-time measurements of chemical properties, e.g., dissolved CO2 and its carbon isotopic compositions, dissolved inorganic carbon, water isotopes, etc., are highly desired for understanding various physical and biogeochemical processes in the surface ocean. Due to its high sensitivity, stability and portability, cavity ring-down spectroscopy (CRDS) has been increasingly used as a core technique for shipboard systems that automatically measure properties of oceanographic interest at high spatial-temporal resolution. These systems typically require front-end components that convert the sample into a continuous gas flow that can be continuously sampled by the CRDS. Here, we review the progress in the development of CRDS-based systems for shipboard, high-frequency measurements of various properties in the surface ocean, including pCO2, δ13C-CO2, pCH4, δ13C-CH4, and water isotopes. In most systems, gas extraction devices are keys to the sample preparation units that are coupled with the CRDS analyzers. In our present work, we summarize the major gas extraction techniques used in these methods (e.g. the showerhead-type equilibration, the bubbling equilibration, the high-porosity membrane contactor extraction, the expanded polytetrafluoroethylene-based extraction, etc.), present examples how these techniques are coupled with CRDS analyzers, and evaluate the major factors that determine the overall performance (precision, accuracy, response time, etc.) of the systems. Based on the working principles and field data generated by these systems, we were able to identify the major factors that affect the system performance, including the efficiency (completeness) of gas extraction, magnitude and stability of isotopic fractionation during the gas extraction, internal volume of the system (e.g., the volume of the equilibration chamber and that of the CRDS cavity) and the carrier gas flow rate. Finally, we make recommendations, for each type of system, the optimal

    1981-04-01

    Sixteen conceptual designs of residential photovoltaic arrays are described. Each design concept was evaluated by an industry advisory panel using a comprehensive set of technical, economic and institutional criteria. Key electrical and mechanical concerns that effect further array subsystem development are also discussed. Three integrated array design concepts were selected by the advisory panel for further optimization and development. From these concepts a single one will be selected for detailed analysis and prototype fabrication. The three concepts selected are: (1) An array of frameless panels/modules sealed in a T shaped zipper locking neoprene gasket grid pressure fitted into an extruded aluminum channel grid fastened across the rafters. (2) An array of frameless modules pressure fitted in a series of zipper locking EPDM rubber extrusions adhesively bonded to the roof. Series string voltage is developed using a set of integral tongue connectors and positioning blocks. (3) An array of frameless modules sealed by a silicone adhesive in a prefabricated grid of rigid tape and sheet metal attached to the roof.

  3. Price and income elasticities of residential energy demand in Germany

    Schulte, Isabella; Heindl, Peter

    2017-01-01

    We apply a quadratic expenditure system to estimate price and expenditure elasticities of residential energy demand (electricity and heating) in Germany. Using official expenditure data from 1993 to 2008, we estimate an expenditure elasticity for electricity of 0.3988 and of 0.4055 for space heating. The own price elasticity for electricity is −0.4310 and −0.5008 in the case of space heating. Disaggregation of households by expenditure and socio-economic composition reveals that the behavioural response to energy price changes is weaker (stronger) for low-income (top-income) households. There are considerable economies of scale in residential energy use but scale effects are not well approximated by the new OECD equivalence scale. Real increases in energy prices show a regressive pattern of incidence, implying that the welfare consequences of direct energy taxation are larger for low income households. The application of zero-elasticities in assessments of welfare consequences of energy taxation strongly underestimates potential welfare effects. The increase in inequality is 22% smaller when compared to the application of disaggregated price and income elasticities as estimated in this paper. - Highlights: • We estimate price, income, and expenditure elasticities for residential energy demand in Germany. • We differentiate elasticities by income groups and household type. • Electricity and space heating are necessary goods since the expenditure elasticities are smaller than unity. • Low-income households show a weaker reaction to changing prices when compared to high-income households. • Direct energy taxation has regressive effects, meaning that larger burdens fall upon low-income households.

  4. Social implications of residential demand response in cool temperate climates

    2012-01-01

    Residential electrical demand response (DR) offers the prospect of reducing the environmental impact of electricity use, and also the supply costs. However, the relatively small loads and numerous actors imply a large effort: response ratio. Residential DR may be an essential part of future smart grids, but how viable is it in the short to medium term? This paper reviews some DR concepts, then evaluates the propositions that households in cool temperate climates will be in a position to contribute to grid flexibility within the next decade, and that that they will allow some automated load control. Examples of demand response from around the world are discussed in order to assess the main considerations for cool climates. Different tariff types and forms of control are assessed in terms of what is being asked of electricity users, with a focus on real-time pricing and direct load control in energy systems with increasingly distributed resources. The literature points to the significance of thermal loads, supply mix, demand-side infrastructure, market regulation, and the framing of risks and opportunities associated with DR. In concentrating on social aspects of residential demand response, the paper complements the body of work on technical and economic potential. - Highlights: ► Demand response implies major change in governance of electricity systems. ► Households in cool temperate climates can be flexible, mainly with thermal loads. ► DR requires simple tariffs, appropriate enabling technology, education, and feedback. ► Need to test consumer acceptance of DR in specific conditions. ► Introduce tariffs with technologies e.g., TOU tariff plus DLC with electric vehicles.

    In plant research, radioisotope imaging provides useful information about physiological activities in various tissues and elemental transport between plant organs. To expand the usage of imaging techniques, a new system was developed to visualize beta particles, x-rays and gamma-rays emitted from plant bodies. This real-time radioisotope imaging system (RRIS) visualizes radioactivity after conversion into light with a CsI(Tl) scintillator plate. Herein, the RRIS detection properties of the gamma-ray emitters (22)Na, (65)Zn, (86)Rb, (109)Cd and (137)Cs were evaluated in comparison with those of radioluminography (RLG) using an imaging plate. The lower quantitative detection limit (Bq mm(-2)) during a 15 min period ranged from 0.1 to 4, depending on the nuclide, similar to that of RLG. When the quantitative ability to detect radiation from various Arabidopsis tissues was analyzed, the quantitative capability in silique and the thick internode tended to be low. In an EGS5 simulation, beta particles were the greatest contributors to RRIS imaging of (22)Na, (86)Rb and (137)Cs, and low-energy x-rays contributed significantly to (65)Zn and (109)Cd detection. Thus, both self-absorption and air space between the sample and scintillator surface could impair quantitative RRIS imaging. Despite these issues, RRIS is suggested for quantitative time-course measurements of radionuclide motion within plants.

    Risk assessment and evaluation becomes essential for financial institution to measure the potential risk of their counterparties. In middle of 2016 until first quarter of 2017, there is national program from Indonesian government so-called Tax Amnesty. One subsector that has potential to receive positive impact from the Tax Amnesty program is property and real estate. This work evaluates the risk of top five companies in term of capital share listed in Indonesia stock exchange (IDX). To do this, the Value-at-Risk (VaR) with ARMAX-GARCHX approach is employed. The ARMAX-GARCHX simultaneously models the adaptive mean and variance of stock return of each company considering exogenous variables, i.e. IDR/USD exchange rate and Jakarta Composite Index (JCI). The risk is evaluated in scheme of time moving window. The risk evaluation using 5% quantile with window size 500 transaction days perform better result compare to other scenarios. In addition, duration test is used to test the dependency between shortfalls. It informs that series of shortfall are independent.

  10. Measuring the Externality Effects of Commercial Land Use on Residential Land Value: A Case Study of Seoul

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available Two contrasting theories purport to explain the effects of neighborhood non-residential use on residential property values. In traditional zoning theory, separating land from commercial land use is considered to protect residential environments from negative externalities such as noise, litter, and congestion. By contrast, contemporary planning principles including Smart Growth emphasize positive impacts of mixed land use on residential environment, which lead to more walkable and sustainable communities. This study attempts to empirically investigate how positive and negative externalities of commercial land use, referred to as “proximity effects” and “disamenity effects” respectively, affect residential land values. Using data gathered in Seoul, we pay attention to two particular aspects of commercial land use: spatial concentration and neighborhood scale. Spatial concentration is determined by the number of commercial employees present in the buffer zone around an individual residential parcel. We model four geographically distinct neighborhood scales as we compare spatial concentrations in and across commercial zones. Quadratic regression analyses of our data show the trade-off relationship that a higher spatial concentration of commercial land use in a neighborhood initially results in increased residential land values, but drops off beyond a threshold level by excessive noise or crowding.

    Characteristics of patients living in residential care facilities and the availability of mental hospital- and residential beds in Italy and The Netherlands were compared to assess whether differences in the process of deinstitutionalisation have influenced the composition of their residential patient populations. Data from the Dutch UTOPIA-study (UTilization & Outcome of Patients In the Association of Dutch residential care providers) and the Italian PROGRES-study were used. Dutch residents were more likely to suffer from substance or alcohol abuse than Italian residents. The latter were more likely to suffer from schizophrenia or a related disorder, less likely to have experienced mental hospital admissions and showed an overall shorter duration of stay in residential care facilities. Contrary to our expectations Dutch residents, who still have good access to long stay beds in mental hospitals, are not less disabled than Italian residents. Finally, the number of beds in residential care facilities per 10,000 inhabitants in the Netherlands is twice (6) as high as in Italy (3). The Italian and Dutch deinstitutionalisation processes have resulted in a different availability in the number of residential beds. However, it did not influence the overall level of functioning of both residential populations.

    The air quality impacts of residential cordwood stoves have been of concern to regulators, energy planners, and members of the woodstove industry. In addition, the reliability of laboratory certification emission values in predicting 'real world' emissions has been questioned. In response to these concerns, particulate emissions from residential cordwood stoves under actual in-home use have been measured for 5 heating seasons as part of 12 separate studies in Oregon, New York, Vermont, and the Yukon Territory. Monitoring was conducted using an automated emission sampler (AES) system. The system has been deployed in nearly 100 individual homes. Typically, emissions from several 1-week-long integrated sampling periods over the course of the heating season were measured with the AES system at each home. Particulate emission rates in grams of particles per hour of stove operation, grams of particles per kilogram of dry wood burned, and grams of particles per million Joules were calculated. Ancillary data provided by the studies included wood burn rates, homeowner wood loading patterns, wood moisture content and species, hours of operation of auxiliary heating appliances in the study homes, room ambient, flue gas, catalyst, and pre-catalyst temperatures, and hours of catalyst operation. Conventional stoves, high-technology non-catalytic stoves, catalytic stoves, and stoves equipped with retrofit catalytic devices have been studied. In addition to the 12 cordwood stove studies, the AES system has been used in 2 pellet stove studies and 1 fireplace study

    Highlights: • Applying colonial competitive algorithm to the problem of optimal dispatching. • Economic modeling of the residential integrated energy system. • Investigating differences of stand-alone and system-connected modes of fuel cell operation. • Considering uncertainty on the electrical load. • The effects of battery capacity and its efficiency on the system is investigated. - Abstract: In this paper the combined heat and power functionality of a fuel-cell in a residential hybrid energy system, including a battery, is studied. The demand uncertainties are modeled by investigating the stochastic load behavior by applying Monte Carlo simulation. The colonial competitive algorithm is adopted to the hybrid energy system scheduling problem and different energy resources are optimally scheduled to have optimal operating cost of hybrid energy system. In order to show the effectiveness of the colonial competitive algorithm, the results are compared with the results of the harmony search algorithm. The optimized scheduling of different energy resources is listed in an efficient look-up table for all time intervals. The effects of time of use and the battery efficiency and its size are investigated on the operating cost of the hybrid energy system. The results of this paper are expected to be used effectively in a real hybrid energy system.

    2015-08-01

    Full Text Available This paper analyzes the different roots of current residential high-rise clusters emerging in new city districts along the coast of Bahrain’s capital city Manama, and the resulting urban planning and design challenges. Since the local real-estate markets were liberalized in Bahrain in 2003, the population grew rapidly to more than one million inhabitants. Consequently, the housing demand increased rapidly due to extensive immigration. Many residential developments were however constructed for the upper spectrum of the real-estate market, due to speculative tendencies causing a raise in land value. The emerging high-rise clusters are developed along the various waterfronts of Manama on newly reclaimed land. This paper explores the spatial consequences of the recent boom in construction boom and the various challenges for architects and urban planners to enhance urban qualities.

    This study examined a range of factors influencing energy consumption in households that had participated in residential energy-efficiency upgrades. The study was funded by a grant from the U.S. Department of Energy’s Pacific Northwest National Laboratory and was conducted by faculty and staff of Portland State University Center for Urban Studies and Department of Economics. This work was made possible through the assistance and support of the Energy Trust of Oregon (ETO), whose residential energy-efficiency programs provided the population from which the sample cases were drawn. All households in the study had participated in the ETO Home Performance with Energy Star (HPwES) program. A number of these had concurrently pursued measures through other ETO programs. Post-retrofit energy outcomes are rarely investigated on a house-by-house basis. Rather, aggregate changes are ordinarily the focus of program impact evaluations, with deviation from aggregate expectations chalked up to measurement error, the vagaries of weather and idiosyncrasies of occupants. However, understanding how homes perform post-retrofit on an individual basis can give important insights to increase energy savings at the participant and the programmatic level. Taking a more disaggregated approach, this study analyzed energy consumption data from before and after the retrofit activity and made comparisons with engineering estimates for the upgrades, to identify households that performed differently from what may have been expected based on the estimates. A statistical analysis using hierarchal linear models, which accounted for weather variations, was performed looking separately at gas and electrical use during the periods before and after upgrades took place. A more straightforward comparison of billing data for 12-month periods before and after the intervention was also performed, yielding the majority of the cases examined. The later approach allowed total energy use and costs to be

    Full Text Available Despite the existing literature regarding institutional influence ontraditional commons, there is still a comparative dearth of research that theorisesproperty-rights structure and its impact on contemporary commons. This isparticularly true for public open space (POS governance: its management andutilisation and hence its quality, of which underinvestment and overexploitationleads to increasingly negative externalities and outcomes. An interdisciplinarystudy is employed here to depict the relationships of diverse property-rightsstructure attributes – POS title existence, community existence, POS title transfer and POS site handing-over period to local government – with quality ofresidential POS. A cross-sectional survey via direct structured observation witha POS quality audit tool was conducted to collect a randomly stratified sampleof 155 Country Lease (CL POS and entire 22 Native Title (NT POS, from thedistricts of Kota Kinabalu and Penampang, Sabah, respectively. Archival searchand document analysis on data of property-rights attributes were executed aswell.

Results showed that only thesethree property-rights attributes – title deed existence, community existence andPOS site handing-over period to local government- are significantly associatedwith POS quality at significance level (p≤0.05. It is found that, although POSwith title deed and community’s involvement might not contribute to goodquality, these attributes were likely to provide better quality. On the other hand,it is found that the more recent the POS site handing over to government, thehigher the likelihood of good POS quality and vice versa.

    Boman, Christoffer

    2005-04-01

    different stoves were determined with variations in fuel, appliance and operational properties. The emissions of PICs as well as PM tot from wood combustion were in general shown to be considerably higher compared to pellets combustion. PAH tot emissions were determined in the range of 1,300-220,000 μg/MJ for wood stoves and 2-300 μg/MJ for pellet stoves with phenantrene, fluoranthene and pyrene generally found as major PAHs. The PM emissions from present residential appliances was found to consist of significant but varying fractions of PICs, with emissions in the range 35-350 mg/MJ for wood stoves compared to 15-45 mg/MJ for pellet stoves. Accordingly, the use of up-graded biomass fuels, combusted under continuous and controlled conditions give advantageous combustion conditions compared to traditional batch wise firing of wood logs. The importance of high temperature in well mixed isothermal conditions was further illustrated during pellets combustion to obtain complete combustion with almost a total depletion of PICs. Fine (100-300 nm) particles dominated in all studied cases the PM with 80-95% as PM 1 . Beside varying fractions of carbonaceous material, the fine PM consisted of inorganic volatilized ash elements, mainly found as KCl, K 3 Na(SO 4 ) 2 and K 2 SO 4 with mass concentrations at 15-20 mg/MJ during complete combustion. The importance of the behavior of alkali elements for the ash transformation and fine particle formation processes was further shown, since the stability, distributions and compositions also directly control the degree of volatilization. In addition to the alkali metals, zinc was found as an important element in fine particles from residential biomass combustion. Finally, the behaviour of volatile trace elements, e.g. Zn and Cd, during pellets production and combustion were studied. A significant enrichment in the pellet fuel during the drying process was determined. The magnitude and importance of the enrichment was, however, relative small

    The housing estates in Bratislava saturated the housing needs of a large number of inhabitants who come after World War II to the city. Design of public spaces often did not have priority in the process of designing. The solutions for mentioned exterior spaces had been planned after blocks of flat realization, but many of them are not realized to this day. The article analyzes the example of the unrealized public spaces in existing housing estates Devinska Nova Ves and Petržalka (city districts of Bratislava) and offer practical solutions in relation to residencialization method. Residencialization of missing public places is an effective method of adding identities to settlements. It improves the quality of residential environment and public spaces. The main aim is to create better conditions for social activities in public areas, which are missing on the present. The research will be focused on the examination of the urban, cultural and construction potential of the existing residential enviroment in Bratislava. The main aim of residentialization is not only to enhance the quality of spatial and building structures in the selected residential area and maintain long-term sustainability in the pertinent programme area, but mainly to improve the quality of living for the residents. The outputs of the project are proposals and practical procedures developed with regard to planning documents for local municipal authorities and regional organizations. The solutions will have a positive impact on the enhancement of the quality of public spaces, attractive social activities and of a conceptual link - residentialization.

    2012-10-01

    Full Text Available The increasing deployment of distributed generation systems based on renewables in the residential sector, the development of information and communication technologies and the expected evolution of traditional power systems towards smart grids are inducing changes in the passive role of end-users, namely with stimuli to change residential demand patterns. The residential user should be able to make decisions and efficiently manage his energy resources by taking advantages from his flexibility in load usage with the aim to minimize the electricity bill without depreciating the quality of energy services provided. The aim of this paper is characterizing electricity consumption in the residential sector and categorizing the different loads according to their typical usage, working cycles, technical constraints and possible degree of control. This categorization of end-use loads contributes to ascertain the availability of controllable loads to be managed as well as the different direct management actions that can be implemented. The ability to implement different management actions over diverse end-use load will increase the responsiveness of demand and potentially raises the willingness of end-users to accept such activities. The impacts on the aggregated national demand of large-scale dissemination of management systems that would help the end-user to make decisions regarding electricity consumption are predicted using a simulator that generates the aggregated residential sector electricity consumption under variable prices.

    This paper reviews major studies in three traditional lines of research in residential energy consumption in the UK, i.e., economic/infrastructure, behaviour, and load profiling. Based on the review the paper proposes a three-dimensional model for archetyping residential energy consumers in the UK by considering property energy efficiency levels, the greenness of household behaviour of using energy, and the duration of property daytime occupancy. With the proposed model, eight archetypes of residential energy consumers in the UK have been identified. They are: pioneer greens, follower greens, concerned greens, home stayers, unconscientious wasters, regular wasters, daytime wasters, and disengaged wasters. Using a case study, these archetypes of residential energy consumers demonstrate the robustness of the 3-D model in aiding local energy policy/intervention design in the UK. - Highlights: ► This paper reviews the three traditional lines of research in residential energy consumption in the UK. ► Based on the literature review, the paper proposes a 3-D conceptual model for archetyping UK residential energy consumers. ► The 3-D archetype model can aid local energy policy/intervention design in the UK.

    Full Text Available Albania as a country that is already in the market economy, feels the need to raise the level of income, to stabilize the economic problems of equilibrium and balance of payments, leading ultimately to the growth of the country's economic development. Tax on real estate assets, especially the one on residential buildings, is politically sensitive depending on the size and value with which they grow. The transition from the tax base in the area of the Real Estate to the market value of immovable property requires time and proper preparation for this qualitative change to the law of taxation of real estate. The purpose of this article is: Determining the efficiency of the method of taxation of the Immovable Property in improving the qualitative service of public services. The composition of tax revenue according to the type of tax in the OECD countries, revenues from taxation of real estate averaged about 5% of tax revenues.2 Thus, there is room for governments to increase their support on the recurring taxes on real estate. The diversity of methods used for measuring the tax base of real estate is great. What is important and should be understood by policy-makers is the fact that management of the system of taxation of real estate today and in the future should be better evaluated than to date by expanding further basis of taxation of real estate, including in them property which has been neglected so far.

    Ding, Lei; Hwang, Jackelyn; Divringi, Eileen

    2016-11-01

    Gentrification has provoked considerable controversy surrounding its effects on residential displacement. Using a unique individual-level, longitudinal data set, this study examines mobility rates and residential destinations of residents in gentrifying neighborhoods during the recent housing boom and bust in Philadelphia for various strata of residents and different types of gentrification. We find that vulnerable residents, those with low credit scores and without mortgages, are generally no more likely to move from gentrifying neighborhoods compared with their counterparts in nongentrifying neighborhoods. When they do move, however, they are more likely to move to lower-income neighborhoods. Residents in gentrifying neighborhoods at the aggregate level have slightly higher mobility rates, but these rates are largely driven by more advantaged residents. These findings shed new light on the heterogeneity in mobility patterns across residents in gentrifying neighborhoods and suggest that researchers should focus more attention on the quality of residential moves and nonmoves for less advantaged residents, rather than mobility rates alone.

    This report presents the information that homeowners and policy makers need to facilitate PV financing at the residential level. The full range of cash payments, bill savings, and tax incentives is covered, as well as potentially available solar attribute payments. Traditional financing is also compared to innovative solutions, many of which are borrowed from the commercial sector. Together, these mechanisms are critical for making the economic case for a residential PV installation, given its high upfront costs. Unfortunately, these programs are presently limited to select locations around the country. By calling attention to these innovative initiatives, this report aims to help policy makers consider greater adoption of these models to benefit homeowners interested installing a residential PV system.

  10. Residential architecture of George Pavlovic Kovalevsky in interwar Belgrade

    Directory of Open Access Journals (Sweden)

    Vuksanović-Macura Zlata

    2016-01-01

    Full Text Available George Pavlovic Kovalevsky, architect and urban planner, belongs to the most significant authors who created in the period between the Two World Wars in Belgrade. Yet, his work and life have rarely been the subject of scholarly literature, while the study of his housing projects has been overlooked. This paper discusses housing projects designed by Kovalevsky mainly in collaboration with another Russian architect Vladimir Bilinski. The analysis of the projects is based on original archival plans, documents and photographs. Residential buildings designed during 1921-1923 by these two architects include small single-storey houses, multi-storey building and spacious villas. Although of different surface, volume and shape, they have some common characteristics such as: classical construction, equable aesthetic quality that followed the spirit of the late Secession or the modernized Academicism, and were designed in line with the requirements of the property-owners. Buildings created by Kovalevsky and Bilinski cannot be considered among the most important achievements of the interwar Belgrade residential architecture, but their study is important because it contributes to a better understanding and evaluation of the work of these authors, as well as the overall architectural production of that period. In a broader sense, this paper builds upon general rise in interest in the revaluation of cultural, social and historical values of residential architecture in Belgrade that was created in the late 19th and the first half of the 20th century, as an important segment of the material and immaterial cultural heritage and the identity of the city and contributes to its more adequate interpretation and preservation.

    2008-06-01

    Full Text Available Grounded in group conflict theory and the defended neighborhoods thesis, this nationwide empirical study of cities and their residential segregation levels examines the occurrence of hate crime using data for all U.S. cities with populations over 95,000 and Uniform Crime Reporting data for hate crime, in conjunction with 2000 census data. Hate crime is any illegal act motivated by pre-formed bias against, in this case, a person’s real or perceived race. This research asks: Do hate crime levels predict white/black segregation levels? How does hate crime predict different measures of white/black segregation? I use the dissimilarity index measure of segregation operationalized as a continuous, binary, and ordinal variable, to explore whether hate crime predicts segrega- tion of blacks from whites. In cities with higher rates of hate crime there was higher dissimilarity between whites and blacks, controlling for other factors. The segregation level was more likely to be “high” in a city where hate crime occurred. Blacks are continually multiply disadvantaged and distinctly affected by hate crime and residential segregation. Prior studies of residential segregation have focused almost exclusively on individual choice, residents’ lack of finances, or discriminatory actions that prevent racial minorities from moving, to explore the correlates of segregation. Notably absent from these studies are measures reflecting the level of hate crime occurring in cities. This study demonstrates the importance of considering hate crime and neighborhood conflict when contemplating the causes of residential segregation.

  17. Optimization Models and Methods for Demand-Side Management of Residential Users: A Survey

    Directory of Open Access Journals (Sweden)

    Antimo Barbato

    2014-09-01

    Full Text Available The residential sector is currently one of the major contributors to the global energy balance. However, the energy demand of residential users has been so far largely uncontrollable and inelastic with respect to the power grid conditions. With the massive introduction of renewable energy sources and the large variations in energy flows, also the residential sector is required to provide some flexibility in energy use so as to contribute to the stability and efficiency of the electric system. To address this issue, demand management mechanisms can be used to optimally manage the energy resources of customers and their energy demand profiles. A very promising technique is represented by demand-side management (DSM, which consists in a proactive method aimed at making users energy-efficient in the long term. In this paper, we survey the most relevant studies on optimization methods for DSM of residential consumers. Specifically, we review the related literature according to three axes defining contrasting characteristics of the schemes proposed: DSM for individual users versus DSM for cooperative consumers, deterministic DSM versus stochastic DSM and day-ahead DSM versus real-time DSM. Based on this classification, we provide a big picture of the key features of different approaches and techniques and discuss future research directions.

Successfully addressing peak energy concerns requires understanding of all the factors that affect electricity demand especially at peak times. This paper is based on past attempts of proposing models designed to aid our understanding of the influences on residential peak energy demand in a systematic and comprehensive way. Our model has been developed through a group model building process as a systems framework of the problem situation to model the complexity within and between systems and indicate how changes in one element might flow on to others. It is comprised of themes (social, technical and change management options) networked together in a way that captures their influence and association with each other and also their influence, association and impact on appliance usage and residential peak energy demand. The real value of the model is in creating awareness, understanding and insight into the complexity of residential peak energy demand and in working with this complexity to identify and integrate the social, technical and change management option themes and their impact on appliance usage and residential energy demand at peak times.

    Full Text Available The microclimate of a residential landscape can affect both the energy use in your home and the human thermal comfort in your garden, ultimately affecting the heat in the neighbourhood or precinct. A thermal imaging camera provides information about the temperature of surfaces. By using Stefan–Boltzmann’s law and the surface properties, these temperatures can be used to calculate the emission of longwave radiation (radiant exitance in W m−2. A thermal camera was used to determine the amount of radiant exitance from a range of residential landscape elements. A standard procedure for capturing these images was developed, taking into account factors which affect the quality of the radiometric data. A quantitative database comparing this radiation has been compiled for different times of day and different seasons. The sky view factor of these elements was chosen such that it was as close to 1 as possible. For a particular landscape design, areas of each landscape element can be measured and the amount of radiation reduced or emitted at different times can be calculated. This data can be used to improve landscape designs to reduce home energy use and human thermal comfort through shading and reduction of surfaces which emit longwave radiation close to the house.

    Staff Scientist; Walker, Iain; Sherman, Max; Dickerhoff, Darryl

    2011-12-01

    The goal of this study was to develop a Residential Integrated Ventilation Controller (RIVEC) to reduce the energy impact of required mechanical ventilation by 20percent, maintain or improve indoor air quality and provide demand response benefits. This represents potential energy savings of about 140 GWh of electricity and 83 million therms of natural gas as well as proportional peak savings in California. The RIVEC controller is intended to meet the 2008 Title 24 requirements for residential ventilation as well as taking into account the issues of outdoor conditions, other ventilation devices (including economizers), peak demand concerns and occupant preferences. The controller is designed to manage all the residential ventilation systems that are currently available. A key innovation in this controller is the ability to implement the concept of efficacy and intermittent ventilation which allows time shifting of ventilation. Using this approach ventilation can be shifted away from times of high cost or high outdoor pollution towards times when it is cheaper and more effective. Simulations, based on the ones used to develop the new residential ventilation requirements for the California Buildings Energy code, were used to further define the specific criteria and strategies needed for the controller. These simulations provide estimates of the energy, peak power and contaminant improvement possible for different California climates for the various ventilation systems. Results from a field test of the prototype controller corroborate the predicted performance.

    Full Text Available About 40, ground plus one (G+1 residential units were designed using a hybrid structural framing system (RC frame and load bearing walls. A few months after the completion of the ground floor of the residential units, cracks appeared at several locations in the structure. Field and Laboratory testing was conducted to ascertain the in situ strength of concrete and steel reinforcement. The results of the experimental work were used in the analytical ETABS model for the structural stability calculations. The results indicated that residential units were marginally safe in the existing condition (completed ground floor, but the anticipated construction of the floor above the ground floor (G+1 could not be carried out as the strength of the structural system was inadequate. To increase the safety of existing ground floor and to provide the option of the construction of one floor above, rehabilitation and strengthening design was performed. The proposed strengthening design made use of welded wire fabric (WWF and carbon fibre reinforced polymer (CFRP laminates/sheets for the strengthening of walls, columns and slabs. The residential units will be strengthened in the near future.

They prove that if \\Phi is an irreducible classical root system of rank \\geq 2 and G is a group graded by \\Phi, then under certain natural conditions on the grading, the union of the root subgroups is a Kazhdan subset of G. As the main application of this theorem the authors prove that for any reduced irreducible classical root system \\Phi of rank \\geq 2 and a finitely generated commutative ring R with 1, the Steinberg group {\\mathrm St}_{\\Phi}(R) and the elementary Chevalley group \\mathbb E_{\\Phi}(R) have property (T). They also show that there exists a group with property (T) which maps onto all finite simple groups of Lie type and rank \\geq 2, thereby providing a "unified" proof of expansion in these groups.

  14. The impact of VAT introduction on UK residential energy demand: an investigation using the cointegration approach

    International Nuclear Information System (INIS)

    Fouquet, Roger

    1995-01-01

    Over a two-year period, which started in April 1994, the real price of energy to UK households was expected to rise by 17.5% as a result of value-added tax (VAT) introduction. The regressive nature of the tax forced the government to limit VAT on residential fuel to 8%. Using a cointegration approach, to take account of the non-stationarity fuel consumption time series, this paper estimates real energy and fuel specific price and income elasticities for the period 1974:1-1994:1. They suggest that natural gas has a positive real energy price elasticity indicating that, as real price of energy rises, households scrap inefficient heaters and invest in more efficient ones, principally natural gas. These estimates enable projections to be made of the impact of the introduction of VAT and imply a rise in natural gas consumption as a result of the additional VAT, although at the expense of other less efficient fuels.

    Full Text Available This study attempts to assess and compare the residential and non-residential schoolchildren in information-processing skills and creative thinking abilities. A sample of 80 children from Classes 5 and 7 were selected from two types of schools, residential/ashram (02 and non-residential/formal schools (02 in Bolpur subdivision of West Bengal in India where the medium of instruction is Bengali language/mother-tongue. All the children were individually administered the PASS (Planning, Attention, Simultaneous, Successive, Stroop, Matching Familiar Figure Test (MFFT-20, and creative thinking tasks. The residential school children were found to perform better both in information processing and creative thinking tasks. The developmental trend could not be clearly observed due to small sample size, but with increasing age, children were using better processing strategies. Due to ashram environment, creative pedagogy, and various co-curricular activities, the residential school children were found to be more creative than their formal school counterparts. Moreover, some significant positive correlations were found among information processing skills and creative thinking dimensions.

  18. Canals vs. Streams: To What Extent Do Water Quality and Proximity Affect Real Estate Values? A Hedonic Approach Analysis

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available The presence of and proximity to water influences human settlement decisions, because water has been able to characterize the environment and affect human health since prehistoric times. Many scholars have studied the effects of environmental amenities on the real estate market; however, only a few of them have explored the effects of water. This study stresses the role of water with a focus on the dichotomy between artificial and natural waterways (canals vs. streams, which involves managerial and qualitative differences. A hedonic approach, based on a large web scraped and geo-referenced dataset of 10,530 observations, is used to analyze the effect of water proximity and quality on residential housing prices in the province of Milan (Italy. Our main results show a significant but conflicting impact of water proximity on real estate value: reducing the canal distance, we observe an increase in the residential housing sale price, in urban more than peri-urban environments; in contrast, reducing the stream distance, our results show decreases in property value. Moreover, a significant moderating effect of water quality on distance from streams is identifiable.

    This textbook is designed for a year-long course in real analysis taken by beginning graduate and advanced undergraduate students in mathematics and other areas such as statistics, engineering, and economics. Written by one of the leading scholars in the field, it elegantly explores the core concepts in real analysis and introduces new, accessible methods for both students and instructors. The first half of the book develops both Lebesgue measure and, with essentially no additional work for the student, general Borel measures for the real line. Notation indicates when a result holds only for Lebesgue measure. Differentiation and absolute continuity are presented using a local maximal function, resulting in an exposition that is both simpler and more general than the traditional approach. The second half deals with general measures and functional analysis, including Hilbert spaces, Fourier series, and the Riesz representation theorem for positive linear functionals on continuous functions with compact support....

    Full Text Available Abstract Background Older people in long-term residential care are at increased risk of medication prescribing and administration errors. The main aim of this study was to measure the incidence of medication administration errors in nursing and residential homes using a barcode medication administration (BCMA system. Methods A prospective study was conducted in 13 care homes (9 residential and 4 nursing. Data on all medication administrations for a cohort of 345 older residents were recorded in real-time using a disguised observation technique. Every attempt by social care and nursing staff to administer medication over a 3-month observation period was analysed using BCMA records to determine the incidence and types of potential medication administration errors (MAEs and whether errors were averted. Error classifications included attempts to administer medication at the wrong time, to the wrong person or discontinued medication. Further analysis compared data for residential and nursing homes. In addition, staff were surveyed prior to BCMA system implementation to assess their awareness of administration errors. Results A total of 188,249 medication administration attempts were analysed using BCMA data. Typically each resident was receiving nine different drugs and was exposed to 206 medication administration episodes every month. During the observation period, 2,289 potential MAEs were recorded for the 345 residents; 90% of residents were exposed to at least one error. The most common (n = 1,021, 45% of errors was attempting to give medication at the wrong time. Over the 3-month observation period, half (52% of residents were exposed to a serious error such as attempting to give medication to the wrong resident. Error incidence rates were 1.43 as high (95% CI 1.32-1.56 p Conclusions The incidence of medication administration errors is high in long-term residential care. A barcode medication administration system can capture medication

    Dermal and non-dietary pathways are potentially significant exposure pathways to pesticides used in residences. Exposure pathways include dermal contact with residues on surfaces, ingestion from hand- and object-to-mouth activities, and absorption of pesticides into food. A limited amount of data has been collected on pesticide concentrations in various residential compartments following an application. But models are needed to interpret this data and make predictions about other pesticides based on chemical properties. In this paper, we propose a mass-balance compartment model based on fugacity principles. We include air (both gas phase and aerosols), carpet, smooth flooring, and walls as model compartments. Pesticide concentrations on furniture and toys, and in food, are being added to the model as data becomes available. We determine the compartmental fugacity capacity and mass transfer-rate coefficient for wallboard as an example. We also present the framework and equations needed for a dynamic mass-balance model.

    Full Text Available Tax institutions should be construed in a rational manner, in order so as to not restrict economic turnover excessively. The regulations concerning the possibility to resign from the VAT exemption of sales of residential premises by the developer characterizes by the high level of formalism which affects in a negative manner the sales process performed by the developer. This paper is devoted to the fragment of the polish Act on the goods and services tax governing the issue of resignation from the VAT exemption of sales of residential premises, which implies in a certain extent to appeal to the regulation of exemptions stipulated in this Act. The subject matter of this analysis is to examine the correctness of transposition of the Directive 112 into polish legal system in the field of real estate exemptions from VAT, the conditions for exercising the optional exemption, as well as the benefit of the resignation from the VAT exemption by the taxpayer.

  3. Economic Effects Real Estate Tax

    Full Text Available The real estate tax is usually a fiscal instrument which performs the property tax. When it comes to real property or immovable this term include: apartments, houses, land, cottages, excess housing landscape and more. The real estate tax as a form of the fiscal charges ownership or use of certain forms of real estate, and the revenue from this tax is levied on the area where the property is located regardless of the place of residence of its owner. The tax base for the calculation of this tax usually consists of the market, estimated or annuity value of certain real estate. This form of taxation in the Republic of Serbian applies from 1.1.2012., and its introduction has been replaced by former property taxes. The differences between the two concepts mentioned taxes are numerous and significant. Among the more important are: subject to taxation under the new concept of the real estate rather than law, a taxpayer is any property owner rather than the holder of rights to immovable property tax base is the market value of real estate which is replaced by the payment of taxes per square meter of usable area, the rate of property tax is determined local government, which can not be lower than 0.05% of the estimated value of the real estate nor higher than 0.5% of the appraised value of real estate. The last change, ie. The new law on Property Tax from 5.11.2015. was determined by the tax rate to 20%. The fact that local governments each of them determines the tax rate on real estate which range from high to low rates of multiple, makes this tax is progressive. Progression is particularly expressed in the distinction applied tax rates of developed and undeveloped municipalities, where we have a case that less developed tolerate a higher tax burden, which leads to negative economic effects. However, real estate tax has its own economic and social characteristics which must be aligned with the objectives of tax policy. This means that the real estate tax

    The data used were derived from the IPPUR/ITBI/IPTU archive, which contains approximately 2 million annual real estate transactions for the period 1968-88 and more for 1990 for the city of Rio de Janeiro. These registers are maintained for levying taxes and they describe the property, the objective of the transaction, the type, location, size, value as well as participation in the financial system of residency (SFH). This information allows the construction of intraurban mobility matrices, first between 96 neighborhoods of the city and then for 24 administrative regions (RAs) of Rio de Janeiro. Problems were abundant: only 1483 (29%) of 5089 transactions for 1985-88 were used, and 35% for 1990 because of poor data quality. The determinants of intraurban mobility were: 1) demographic (life cycle of families), 2) socioeconomic (changes of employment), and 3) environmental and cultural (dilapidation, violence, pollution, and life style). Mobility trends demonstrated that 46.2% of changes were downward moves and only 33.1% were upward moves. Among upward changes 16.8% involved the acquisition of a new apartment, while among downward moves this constituted only 8.9%. SFH financially assisted the purchase of 14% of upward moves vs. 12.9% of downward moves. Among upward deals in the 6 most favored residential areas, 45.3% of transactions occurred in the city. The moves did not indicate a strong segmentation of the market reaffirming the process of residential segregation between rich and poor people. More than half of real estate acquisitions were realized by families residing in the same RA or in the adjacent RA. More than 75% of transactions for residents of 6 RAs were carried out in the same RA or in adjacent ones. The 10 most important moves (1.74% of all potential moves) involved 21.17% of transactions in the city. The most important moves affected the 3 RAs of Barra da Tijuca of the southern zone, which represented 57.1% of all transactions that occurred in the RA

  5. Dynamic management of integrated residential energy systems

    Science.gov (United States)

    Muratori, Matteo

    This study combines principles of energy systems engineering and statistics to develop integrated models of residential energy use in the United States, to include residential recharging of electric vehicles. These models can be used by government, policymakers, and the utility industry to provide answers and guidance regarding the future of the U.S. energy system. Currently, electric power generation must match the total demand at each instant, following seasonal patterns and instantaneous fluctuations. Thus, one of the biggest drivers of costs and capacity requirement is the electricity demand that occurs during peak periods. These peak periods require utility companies to maintain operational capacity that often is underutilized, outdated, expensive, and inefficient. In light of this, flattening the demand curve has long been recognized as an effective way of cutting the cost of producing electricity and increasing overall efficiency. The problem is exacerbated by expected widespread adoption of non-dispatchable renewable power generation. The intermittent nature of renewable resources and their non-dispatchability substantially limit the ability of electric power generation of adapting to the fluctuating demand. Smart grid technologies and demand response programs are proposed as a technical solution to make the electric power demand more flexible and able to adapt to power generation. Residential demand response programs offer different incentives and benefits to consumers in response to their flexibility in the timing of their electricity consumption. Understanding interactions between new and existing energy technologies, and policy impacts therein, is key to driving sustainable energy use and economic growth. Comprehensive and accurate models of the next-generation power system allow for understanding the effects of new energy technologies on the power system infrastructure, and can be used to guide policy, technology, and economic decisions.

    2017-03-01

    Full Text Available Vast metropolitan areas include both urban areas and rural outskirts. Between these areas, there are strong links to the point which they cannot be examined separately. There is a contemporary presence of residential function and working activity in the rural outskirts, as well as in the typical sector of agriculture. Therefore, the production of goods and services for the city requires a combined analysis, due to the large territory which it has to consider. The evolution of the population of such a large territory can be studied in great detail, with reference to the single census area and with the use of Geographic Information Systems (GIS. This means that such a demographic development produces an effect on the values of the urban real estate. This work demonstrates the existing interconnections between urban areas and rural outskirts. Data collection on trends of the population living in the Naples metropolitan area and the house prices associated with this area, and the post spatial processing of such data, allows for the establishment of thematic maps according to which a model capable of interpreting the population development is defined. A study of the statistical correlations shows the consequences that the population dynamics produce for property prices. In addition, the diachronic analysis of the sales prices of residential buildings demonstrates that economic functions, exclusive of certain urban or rural territories, end up distributing and integrating.

  8. Residential Tourism and Multiple Mobilities: Local Citizenship and Community Fragmentation in Costa Rica

    Directory of Open Access Journals (Sweden)

    Femke van Noorloos

    2013-02-01

    Full Text Available Current patterns of “move-in move-out” hypermobility are perfectly exemplified by residential tourism: the temporary or permanent mobility of relatively well-to-do citizens from mostly western countries to a variety of tourist destinations, where they buy property. The mobility of residential tourists does not stand alone, but has broader chain effects: it converts local destinations into transnational spaces, leading to a highly differentiated and segmented population landscape. In this article, residential tourism’s implications in terms of local society in Guanacaste, Costa Rica, are examined, starting from the idea that these implications should be viewed as complex and traveling in time and space. Mobile groups, such as residential tourists, can have an important local participation and involvement (independently of national citizenship, although recent flows of migrants settle more into compatriot social networks. The fact that various migrant populations continually travel back and forth and do not envision a future in the area may restrict their opportunities and willingness for local involvement. Transnational involvement in itself is not a problem and can be successfully combined with high local involvement; however, the great level of fragmentation, mobility, temporariness and absenteeism in Guanacaste circumscribes successful community organizing. Still, the social system has not completely dissolved.

  9. Does Immigrant Residential Crowding Reflect Hidden Homelessness?

    Directory of Open Access Journals (Sweden)

    Michael Haan

    2011-01-01

    Full Text Available Compared to the Canadian-born, immigrants are under-represented among Canada’s homeless population, when their decline in economic wellbeing is considered alongside their relative absence in homeless shelters. One way to explain this oddity, proposed in both academic and popular literature, is that immigrant communities employ unique avoidance strategies, such as within-group co-residence, to help keep co-ethnics off the streets and out of homeless shelters. In this paper I use the 2001 census of Canada to investigate the extent to which heightened levels of residential crowding might reflect “hidden homelessness”. I find mixed evidence to support this link, and, if anything, find some evidence to suggest that the link between residential crowding and hidden homelessness, if one exists, is strongest for the Canadian-born.

    This study estimates the electricity demand function for the residential sector of South Korea with the aim of examining the effects of improved energy efficiency, structural factors and household lifestyles on electricity consumption. In the study, time series data for the period from 1973 to 2007 is used in a structural time series model to estimate the long-term price and income elasticities and annual growth of underlying energy demand trend (UEDT) at the end of the estimation period. The result shows a long-term income elasticity of 1.33 and a long-term price elasticity of -0.27% with -0.93% as the percentage growth of UEDT at the end of the estimation period. This result suggests that, in order to encourage energy efficiency in the residential sector, the government should complement the market based pricing policies with non-market policies such as minimum energy efficiency standards and public enlightenment.

  12. Residential indoor air quality guideline : ozone

    International Nuclear Information System (INIS)

    2010-01-01

    Ozone (O 3 ) is a colourless gas that reacts rapidly on surfaces and with other constituents in the air. Sources of indoor O 3 include devices sold as home air cleaners, and some types of office equipment. Outdoor O 3 is also an important contributor to indoor levels of O 3 , depending on the air exchange rate with indoor environments. This residential indoor air quality guideline examined factors that affect the introduction, dispersion and removal of O 3 indoors. The health effects of prolonged exposure to O 3 were discussed, and studies conducted to evaluate the population health impacts of O 3 were reviewed. The studies demonstrated that there is a significant association between ambient O 3 and adverse health impacts. Exposure guidelines for residential indoor air quality were discussed. 14 refs.

    Allen, Lee R.; Allen, Sharon

    1983-03-01

    Infrared thermography has proven to be a valuable tool in the detection of heat loss in both commercial and residential buildings. The field of residential thermography has needed a simple method with which to report the deficiencies found during an infrared scan. Two major obstacles hindering the cost effectiveness of residential thermography have been 1) the ability to quickly transport some high resolution imaging system equipment from job site to job site without having to totally dismount the instruments at each area, and 2) the lack of a standard form with which to report the findings of the survey to the customer. Since the industry has yet to provide us with either, we believed it necessary to develop our own. Through trial and error, we have come up with a system that makes interior residential thermography a profitable venture at a price the homeowner can afford. Insulation voids, or defects can be instantly spotted with the use of a thermal imaging system under the proper conditions. A special hand-held device was developed that enables the thermographer to carry the equipment from house to house without the need to dismantle and set up at each stop. All the necessary components are attached for a total weight of about 40 pounds. The findings are then conveyed to a form we have developed. The form is simple enough that the client without special training in thermography can understand. The client is then able to locate the problems and take corrective measures or give it to a con-tractor to do the work.

  20. Procedures for Calculating Residential Dehumidification Loads

    Residential building codes and voluntary labeling programs are continually increasing the energy efficiency requirements of residential buildings. Improving a building's thermal enclosure and installing energy-efficient appliances and lighting can result in significant reductions in sensible cooling loads leading to smaller air conditioners and shorter cooling seasons. However due to fresh air ventilation requirements and internal gains, latent cooling loads are not reduced by the same proportion. Thus, it's becoming more challenging for conventional cooling equipment to control indoor humidity at part-load cooling conditions and using conventional cooling equipment in a non-conventional building poses the potential risk of high indoor humidity. The objective of this project was to investigate the impact the chosen design condition has on the calculated part-load cooling moisture load, and compare calculated moisture loads and the required dehumidification capacity to whole-building simulations. Procedures for sizing whole-house supplemental dehumidification equipment have yet to be formalized; however minor modifications to current Air-Conditioner Contractors of America (ACCA) Manual J load calculation procedures are appropriate for calculating residential part-load cooling moisture loads. Though ASHRAE 1% DP design conditions are commonly used to determine the dehumidification requirements for commercial buildings, an appropriate DP design condition for residential buildings has not been investigated. Two methods for sizing supplemental dehumidification equipment were developed and tested. The first method closely followed Manual J cooling load calculations; whereas the second method made more conservative assumptions impacting both sensible and latent loads.

  2. Metal contamination in environmental media in residential ...

    Science.gov (United States)

    Hard-rock mining for metals, such as gold, silver, copper, zinc, iron and others, is recognized to have a significant impact on the environmental media, soil and water, in particular. Toxic contaminants released from mine waste to surface water and groundwater is the primary concern, but human exposure to soil contaminants either directly, via inhalation of airborne dust particles, or indirectly, via food chain (ingestion of animal products and/or vegetables grown in contaminated areas), is also, significant. In this research, we analyzed data collected in 2007, as part of a larger environmental study performed in the Rosia Montana area in Transylvania, to provide the Romanian governmental authorities with data on the levels of metal contamination in environmental media from this historical mining area. The data were also considered in policy decision to address mining-related environmental concerns in the area. We examined soil and water data collected from residential areas near the mining sites to determine relationships among metals analyzed in these different environmental media, using the correlation procedure in SAS statistical software. Results for residential soil and water analysis indicate that the average values for arsenic (As) (85 mg/kg), cadmium (Cd) (3.2 mg/kg), mercury (Hg) (2.3 mg/kg) and lead (Pb) (92 mg/kg) exceeded the Romanian regulatory exposure levels [the intervention thresholds for residential soil in case of As (25 mg/kg) and Hg

    Hong Kong has almost perfect electricity reliability, the result of substantial investments ultimately financed by electricity consumers who may be willing to accept lower reliability in exchange for lower bills. But consumers with high outage costs are likely to reject the reliability reduction. Our ordered-logit regression analysis of the responses by 1876 households to a telephone survey conducted in June 2013 indicates that Hong Kong residents exhibit a statistically-significant preference for their existing service reliability and rate. Moreover, the average residential cost estimate for a 1-h outage is US$45 (HK$350), topping the estimates reported in 10 of the 11 studies published in the last 10 years. The policy implication is that absent additional compelling evidence, Hong Kong should not reduce its service reliability. - Highlights: • Use a contingent valuation survey to obtain residential preferences for reliability. • Use an ordered logit analysis to estimate Hong Kong's residential outage costs. • Find high outage cost estimates that imply high reliability requirements. • Conclude that sans new evidence, Hong Kong should not reduce its reliability

  4. Sorption of organic gases in residential rooms

    Singer, Brett C.; Hodgson, Alfred T.; Hotchi, Toshifumi; Ming, Katherine Y.; Sextro, Richard G.; Wood, Emily E.; Brown, Nancy J.

    Experiments were conducted to characterize organic gas sorption in residential rooms studied "as-is" with furnishings and material surfaces unaltered and in a furnished chamber designed to simulate a residential room. Results are presented for 10 rooms (five bedrooms, two bathrooms, a home office, and two multi-function spaces) and the chamber. Exposed materials were characterized and areas quantified. A mixture of volatile organic compounds (VOCs) was rapidly volatilized within each room as it was closed and sealed for a 5-h Adsorb phase; this was followed by 30-min Flush and 2-h closed-room Desorb phases. Included were alkane, aromatic, and oxygenated VOCs representing a range of ambient and indoor air pollutants. Three organophosphorus compounds served as surrogates for Sarin-like nerve agents. Measured gas-phase concentrations were fit to three variations of a mathematical model that considers sorption occurring at a surface sink and potentially a second, embedded sink. The 3-parameter sink-diffusion model provided acceptable fits for most compounds and the 4-parameter two-sink model provided acceptable fits for the others. Initial adsorption rates and sorptive partitioning increased with decreasing vapor pressure for the alkanes, aromatics and oxygenated VOCs. Best-fit sorption parameters obtained from experimental data from the chamber produced best-fit sorption parameters similar to those obtained from the residential rooms.

    Predictability in a child's environment is a critical quality of safe, stable, nurturing relationships and environments, which promote wellbeing and protect against maltreatment. Research has focused on residential mobility's effect on this predictability. This study augments such research by analyzing the impact of an instability index-including the lifetime destabilization factors (LDFs) of natural disasters, homelessness, child home removal, multiple moves, parental incarceration, unemployment, deployment, and multiple marriages--on childhood victimizations. The cross-sectional, nationally representative sample of 12,935 cases (mean age = 8.6 years) was pooled from 2008, 2011, and 2014 National Surveys of Children's Exposure to Violence (NatSCEV). Logistic regression models controlling for demographics, socio-economic status, and family structure tested the association between excessive residential mobility, alone, and with LDFs, and past year childhood victimizations (sexual victimization, witnessing community or family violence, maltreatment, physical assault, property crime, and polyvictimization). Nearly 40% of the sample reported at least one LDF. Excessive residential mobility was significantly predictive of increased odds of all but two victimizations; almost all associations were no longer significant after other destabilizing factors were included. The LDF index without residential mobility was significantly predictive of increased odds of all victimizations (AOR's ranged from 1.36 to 1.69), and the adjusted odds ratio indicated a 69% increased odds of polyvictimization for each additional LDF a child experienced. The LDF index thus provides a useful alternative to using residential moves as the sole indicator of instability. These findings underscore the need for comprehensive supports and services to support stability for children and families. Copyright © 2018. Published by Elsevier Ltd.

    The growing energy consumption in the residential sector represents about 30% of global demand. This calls for Demand Side Management solutions propelling change in behaviors of end consumers, with the aim to reduce overall consumption as well as shift it to periods in which demand is lower and where the cost of generating energy is lower. Demand Side Management solutions require detailed knowledge about the patterns of energy consumption. The profile of electricity demand in the residential sector is highly correlated with the time of active occupancy of the dwellings; therefore in this study the occupancy patterns in Spanish properties was determined using the 2009–2010 Time Use Survey (TUS), conducted by the National Statistical Institute of Spain. The survey identifies three peaks in active occupancy, which coincide with morning, noon and evening. This information has been used to input into a stochastic model which generates active occupancy profiles of dwellings, with the aim to simulate domestic electricity consumption. TUS data were also used to identify which appliance-related activities could be considered for Demand Side Management solutions during the three peaks of occupancy. -- Highlights: •Active occupancy profiles of Spanish dwellings has been obtained and modeled from Time Use Survey data. •Occupancy profiles resulting from the model can be used to model domestic energy consumption. •The presence of three peaks of active occupation was verified, which coincide with morning, noon and evening. •Manual and incentive-based DSM programmes are considered the most suitable for Spanish dwellings. •TV electricity consumption becomes important at aggregate level

  18. Fertility expectations and residential mobility in Britain

    Directory of Open Access Journals (Sweden)

    John Ermisch

    2016-12-01

    Full Text Available Background: It is plausible that people take into account anticipated changes in family size in choosing where to live. But estimation of the impact of anticipated events on current transitions in an event history framework is challenging because expectations must be measured in some way and, like indicators of past childbearing, expected future childbearing may be endogenous with respect to housing decisions. Objective: The objective of the study is to estimate how expected changes in family size affect residential movement in Great Britain in a way which addresses these challenges. Methods: We use longitudinal data from a mature 18-wave panel survey, the British Household Panel Survey, which incorporates a direct measure of fertility expectations. The statistical methods allow for the potential endogeneity of expectations in our estimation and testing framework. Results: We produce evidence consistent with the idea that past childbearing mainly affects residential mobility through expectations of future childbearing, not directly through the number of children in the household. But there is heterogeneity in response. In particular, fertility expectations have a much greater effect on mobility among women who face lower costs of mobility, such as private tenants. Conclusions: Our estimates indicate that expecting to have a(nother child in the future increases the probability of moving by about 0.036 on average, relative to an average mobility rate of 0.14 per annum in our sample. Contribution: Our contribution is to incorporate anticipation of future events into an empirical model of residential mobility. We also shed light on how childbearing affects mobility.

    Older people in long-term residential care are at increased risk of medication prescribing and administration errors. The main aim of this study was to measure the incidence of medication administration errors in nursing and residential homes using a barcode medication administration (BCMA) system. A prospective study was conducted in 13 care homes (9 residential and 4 nursing). Data on all medication administrations for a cohort of 345 older residents were recorded in real-time using a disguised observation technique. Every attempt by social care and nursing staff to administer medication over a 3-month observation period was analysed using BCMA records to determine the incidence and types of potential medication administration errors (MAEs) and whether errors were averted. Error classifications included attempts to administer medication at the wrong time, to the wrong person or discontinued medication. Further analysis compared data for residential and nursing homes. In addition, staff were surveyed prior to BCMA system implementation to assess their awareness of administration errors. A total of 188,249 medication administration attempts were analysed using BCMA data. Typically each resident was receiving nine different drugs and was exposed to 206 medication administration episodes every month. During the observation period, 2,289 potential MAEs were recorded for the 345 residents; 90% of residents were exposed to at least one error. The most common (n = 1,021, 45% of errors) was attempting to give medication at the wrong time. Over the 3-month observation period, half (52%) of residents were exposed to a serious error such as attempting to give medication to the wrong resident. Error incidence rates were 1.43 as high (95% CI 1.32-1.56 p < 0.001) in nursing homes as in residential homes. The level of non-compliance with system alerts was very low in both settings (0.075% of administrations). The pre-study survey revealed that only 12/41 staff administering

    Highlights: ► We determine the optimal Generation optimization scheme of Microgrid. ► We employ Genetic Algorithm to the environmental/economic problem of the MG. ► We captured the optimal behavior of the MG with high accuracy even with new six different cases. - Abstract: This paper proposes a generalized formulation to determine the optimal operating strategy and cost optimization scheme for a MicroGrid (MG) for residential application. Genetic Algorithm is applied to the environmental/economic problem of the MG. The proposed problem is formulated as a nonlinear constrained MO optimization problem. Prior to the optimization of the microgrid itself, models for the system components are determined using real data. The proposed cost function takes into consideration the costs of the emissions, NOx, SO 2 , and CO 2 , start up costs, as well as the operation and maintenance costs. The MG considered in this paper consists of a wind turbine, a microturbine, a diesel generator, a photovoltaic array, a fuel cell, and a battery storage. The optimization is aimed at minimizing the cost function of the system while constraining it to meet the costumer demand and safety of the system. We also add a daily income and outgo from sale or purchased power. The results demonstrate the efficiency of the proposed approach to satisfy the load and to reduce the cost and the emissions. The comparison with other techniques demonstrates the superiority of the proposed approach and confirms its potential to solve the problem.

  1. Cheap type solar bioclimatic individual houses for residential areas

    2016-01-01

    Full Text Available In the Romanian architectural practice for individual houses in residential areas, designing the architectural object in order to function together with the nature is neglected in the majority of the situations. This happens despite of a great variety of the solar bioclimatic solutions materialized in the traditional houses of all the Romanian geographical regions in a history of over 2000 years of traditional architecture. Unfortunately, in the local real estate realities, other choices are preferred in instead those of the solar bioclimatic architecture. The approach starts with a historical approach, analyzing several examples of traditional houses from all the regions of Romania, in order to identify the traditional bioclimatic solutions used to better adapt to the environment. This constitutes the source of inspiration for the modern cheap type solar bioclimatic houses presented. But a way of thinking should be changed for it, with the help of the Romanian state transformed in financial and legislative realities. These cheap type solar bioclimatic individual houses are destined for the middle class families and involve minimum costs for building and living, creating the best premises to efficiently use one or all of the complementary systems for producing, storage and/or transforming the energy from the environment (using solar, wind, water and/or earth energy.

  2. Designing, building, and testing a solar thermoelectric generation, STEG, for energy delivery to remote residential areas in developing regions

    Moumouni, Yacouba

    New alternatives and inventive renewable energy techniques which encompass both generation and power management solutions are fundamental for meeting remote residential energy supply and demand today, especially if the grid is quasi-inexistent. Solar thermoelectric generators can be a cost-effective alternative to photovoltaics for a remote residential household power supply. A complete solar thermoelectric energy harvesting system is presented for energy delivery to remote residential areas in developing regions. To this end, the entire system was built, modeled, and then validated with LTspice simulator software via thermal-to-electrical analogy schemes. Valuable data in conjunction with two novel LTspice circuits were obtained, showing the achievability of analyzing transient heat transfer with the Spice simulator. Hence, the proposed study begins with a comprehensive method of extracting thermal parameters that appear in thermoelectric modules. A step-by-step procedure was developed and followed to succinctly extract parameters, such as the Seebeck coefficient, electrical conductivity, thermal resistance, and thermal conductivity needed to model the system. Data extracted from datasheet, material properties, and geometries were successfully utilized to compute the thermal capacities and resistances necessary to perform the analogy. In addition, temperature variations of the intrinsic internal parameters were accounted for in this process for accuracy purposes. The steps that it takes to simulate any thermo-electrical system with the LTspice simulator are thoroughly explained in this work. As a consequence, an improved Spice model for a thermoelectric generator is proposed. Experimental results were compiled in the form of a lookup table and then fed into the Spice simulator using the piecewise linear (PWL) command in order to validate the model. Experimental results show that a temperature differential of 13.43°C was achievable whereas the simulation indicates

    In this report, we identify and describe 24 practical diagnostics that are ready now to evaluate residential commissioning metrics, and that we expect to include in the commissioning guide. Our discussion in the main body of this report is limited to existing diagnostics in areas of particular concern with significant interactions: envelope and HVAC systems. These areas include insulation quality, windows, airtightness, envelope moisture, fan and duct system airflows, duct leakage, cooling equipment charge, and combustion appliance backdrafting with spillage. Appendix C describes the 83 other diagnostics that we have examined in the course of this project, but that are not ready or are inappropriate for residential commissioning. Combined with Appendix B, Table 1 in the main body of the report summarizes the advantages and disadvantages of all 107 diagnostics. We first describe what residential commissioning is, its characteristic elements, and how one might structure its process. Our intent in this discussion is to formulate and clarify these issues, but is largely preliminary because such a practice does not yet exist. Subsequent sections of the report describe metrics one can use in residential commissioning, along with the consolidated set of 24 practical diagnostics that the building industry can use now to evaluate them. Where possible, we also discuss the accuracy and usability of diagnostics, based on recent laboratory work and field studies by LBNL staff and others in more than 100 houses. These studies concentrate on evaluating diagnostics in the following four areas: the DeltaQ duct leakage test, air-handler airflow tests, supply and return grille airflow tests, and refrigerant charge tests. Appendix A describes those efforts in detail. In addition, where possible, we identify the costs to purchase diagnostic equipment and the amount of time required to conduct the diagnostics. Table 1 summarizes these data. Individual equipment costs for the 24

    Lipfert, F W; Dungan, J L

    1983-03-25

    An empirical relation between residential firewood use and population density was developed from survey data for 64 counties in New England and was corroborated by data from other states. The results indicate that usage is concentrated in urbanized areas of the Northeast and north central states and that about 9.0 to 11.0 percent of U.S. space heating input is from firewood. No constraints due to the supply of wood were apparent in 1978-1979. These findings have implications for effects on air quality.

    The Residential Energy Consumption Survey (RECS) is a periodic national survey that provides timely information about energy consumption and expenditures of U.S. households and about energy-related characteristics of housing units. The survey was first conducted in 1978 as the National Interim Energy Consumption Survey (NIECS), and the 1979 survey was called the Household Screener Survey. From 1980 through 1982 RECS was conducted annually. The next RECS was fielded in 1984, and since then, the survey has been undertaken at 3-year intervals. The most recent RECS was conducted in 1993.

    1979-08-01

    The residential/commercial market sector, particularly as it relates to energy technologies, is described. Buildings account for about 25% of the total energy consumed in the US. Market response to energy technologies is influenced by several considerations. Some considerations discussed are: industry characteristics; market sectors; energy-consumption characeristics; industry forecasts; and market influences. Market acceptance may be slow or nonexistent, the technology may have little impact on energy consumption, and redesign or modification may be necessary to overcome belatedly perceived market barriers. 7 figures, 20 tables.

    Soils provide the service of attenuating and detoxifying pollutants. Such ability, natural attenuation capacity (NAC), is one of the most important ecosystem services for urban soils. We improved the ecosystem-service performance index (EPX) model by integrating with entropy weight determination method to evaluate the NAC of residential soils in Beijing. Eleven parameters related to the soil process of pollutants fate and transport were selected and 115 residential soil samples were collected. The results showed that bulk density, microbial functional diversity and soil organic matter had high weights in the NAC evaluation. Urban socio-economic indicators of residential communities such as construction age, population density and property & management fee could be employed in kinetic fittings of NAC. It could be concluded urbanization had significant impacts on NAC in residential soils. The improved method revealed reasonable and practical results, and it could be served as a potential measure for application to other quantitative assessment. Copyright © 2018 Elsevier Ltd.

    2016-12-01

    Full Text Available The study presented herein represents a field with good present and future perspectives, especially because real estate property is not under the incidence of a single normative act regarding the sale-purchase agreement of such goods, and given the fact that there are specific legal provisions with respect to various real estate categories and the localization of such property. The article deals with the sale-purchase agreement of various real estate categories, such as fields, buildings, the correspondent lots, urban area, farm, and forests fields, focusing on some particularities. A special care is attributed to examining the applicable laws with regard to the purchase agreements of field lands, the special conditions to be taken into account, the persons that may act as buyers, including foreigners, those without citizenship, and legal persons of a nationality other than Romanian. Finally, a special concern is given to the formalities required for legally exerting the pre-emptive right and the applicable sanctions in that respect.

  13. Life-cycle energy of residential buildings in China

    Chang, Yuan; Ries, Robert J.; Wang, Yaowu

    2013-01-01

    In the context of rapid urbanization and new construction in rural China, residential building energy consumption has the potential to increase with the expected increase in demand. A process-based hybrid life-cycle assessment model is used to quantify the life-cycle energy use for both urban and rural residential buildings in China and determine the energy use characteristics of each life cycle phase. An input–output model for the pre-use phases is based on 2007 Chinese economic benchmark data. A process-based life-cycle assessment model for estimating the operation and demolition phases uses historical energy-intensity data. Results show that operation energy in both urban and rural residential buildings is dominant and varies from 75% to 86% of life cycle energy respectively. Gaps in living standards as well as differences in building structure and materials result in a life-cycle energy intensity of urban residential buildings that is 20% higher than that of rural residential buildings. The life-cycle energy of urban residential buildings is most sensitive to the reduction of operational energy intensity excluding heating energy which depends on both the occupants' energy-saving behavior as well as the performance of the building itself. -- Highlights: •We developed a hybrid LCA model to quantify the life-cycle energy for urban and rural residential buildings in China. •Operation energy in urban and rural residential buildings is dominant, varying from 75% to 86% of life cycle energy respectively. •Compared with rural residential buildings, the life-cycle energy intensity of urban residential buildings is 20% higher. •The life-cycle energy of urban residential buildings is most sensitive to the reduction of daily activity energy

    2013-07-01

    Sevenson Environmental Services, Inc., (Sevenson) has performed several radiological remediation projects located in residential urban areas. Over the course of these projects, there has been a wide variety of experiences encountered from construction related issues to unique social situations. Some of the construction related issues included the remediation of interior basements where contaminated material was located under the footers of the structure or was used in the mortar between cinder block or field stone foundations. Other issues included site security, maintaining furnaces or other utilities, underpinning, backfilling and restoration. In addition to the radiological hazards associated with this work there were occupational safety and industrial hygiene issues that had to be addressed to ensure the safety and health of neighboring properties and residents. The unique social situations at these job sites have included arson, theft/stolen property, assault/battery, prostitution, execution of arrest warrants for residents, discovery of drugs and paraphernalia, blood borne pathogens, and unexploded ordnance. Some of these situations have become a sort of comical urban legend throughout the organization. One situation had historical significance, involving the demolition of a house to save a tree older than the Declaration of Independence. All of these projects typically involve the excavation of early 20. century items such as advertisement signs, various old bottles (milk, Listerine, perfume, whisky) and other miscellaneous common trash items.

  19. Micro-CHP systems for residential applications

    International Nuclear Information System (INIS)

    Paepe, Michel de; D'Herdt, Peter; Mertens, David

    2006-01-01

    Micro-CHP systems are now emerging on the market. In this paper, a thorough analysis is made of the operational parameters of 3 types of micro-CHP systems for residential use. Two types of houses (detached and terraced) are compared with a two storey apartment. For each building type, the energy demands for electricity and heat are dynamically determined. Using these load profiles, several CHP systems are designed for each building type. Data were obtained for two commercially available gas engines, two Stirling engines and a fuel cell. Using a dynamic simulation, including start up times, these five system types are compared to the separate energy system of a natural gas boiler and buying electricity from the grid. All CHP systems, if well sized, result in a reduction of primary energy use, though different technologies have very different impacts. Gas engines seem to have the best performance. The economic analysis shows that fuel cells are still too expensive and that even the gas engines only have a small internal rate of return (<5%), and this only occurs in favourable economic circumstances. It can, therefore, be concluded that although the different technologies are technically mature, installation costs should at least be reduced by 50% before CHP systems become interesting for residential use. Condensing gas boilers, now very popular in new homes, prove to be economically more interesting and also have a modest effect on primary energy consumption

  20. Solar Energy Systems for Ohioan Residential Homeowners

    Luckett, Rickey D.

    Dwindling nonrenewable energy resources and rising energy costs have forced the United States to develop alternative renewable energy sources. The United States' solar energy industry has seen an upsurge in recent years, and photovoltaic holds considerable promise as a renewable energy technology. The purpose of this case study was to explore homeowner's awareness of the benefits of solar energy. Disruptive-innovation theory was used to explore marketing strategies for conveying information to homeowners about access to new solar energy products and services. Twenty residential homeowners were interviewed face-to-face to explore (a) perceived benefits of solar energy in their county in Ohio, and (b) perceptions on the rationale behind the marketing strategy of solar energy systems sold for residential use. The study findings used inductive analyses and coding interpretation to explore the participants' responses that revealed 3 themes: the existence of environmental benefits for using solar energy systems, the expensive cost of equipment associated with government incentives, and the lack of marketing information that is available for consumer use. The implications for positive social change include the potential to enable corporate leaders, small business owners, and entrepreneurs to develop marketing strategies for renewable energy systems. These strategies may promote use of solar energy systems as a clean, renewable, and affordable alternative electricity energy source for the 21st century.

  1. RETHINKING RESIDENTIAL MOBILITY: AN INTERDISCIPLINARY INTERPRETATION

    Directory of Open Access Journals (Sweden)

    Roderick J. Lawrence

    2008-03-01

    Full Text Available Since the 1950s academics and professionals have proposed a number of disciplinary and sector based interpretations of why, when and where households move or choose to stay in the same housing unit at different periods of the life cycle and especially the family cycle. This article challenges studies that only analyse one set of factors. The article stems from a synthesis of 20 years of research by the author who  has an interdisciplinary training in the broad field of people-environment relations. First, it reviews some key concepts related to human ecology, including housing, culture, identity and cultivation. Then it will consider how these concepts can be applied to interpret residential mobility using an interdisciplinary approach. An empirical case study of residential mobility in Geneva, Switzerland is presented in order to show how this approach can help improve our understanding of the motives people have regarding the wish to stay in their residence or to move elsewhere.

  2. Residential proximinity, perceived and acceptable risk

    International Nuclear Information System (INIS)

    Rogers, G.O.

    1984-01-01

    This paper focuses on the relationship between the life experiences associated with residential proximity, and the perception and acceptability of the risks associated with generating electricity in nuclear power plants. Perceived risk is operationally defined in terms of estimated likelihood of occurrence, while acceptability of nuclear power is defined in terms of people's favorable or unfavorable opinions regarding nuclear power plants. In the context of a simple social-structural model of perceived and acceptable risk, four potential explanations for enhanced acceptability among those residentially proximate with nuclear facilities are examined: residents, through the experience of living with hazard, are reinforced toward assigning lower probabilities to the potential risks associated with nuclear facilities; the cognitive dissonance created by the acceptance of the risks associated with nuclear power is decreased by reducing perceived risk; nuclear neighbors are predisposed toward, educated about, and/or economically dependent upon nuclear power hence the more favorable attitudes toward it; nearby residents are systematically more altruistic--other oriented--than the general population and thus more willing to bear the risks associated with nuclear power

  3. Residential fuel choice in the Pacific Northwest

    Energy Technology Data Exchange (ETDEWEB)

    Lee, A.D.; Englin, J.E.; Harkreader, S.A.

    1989-02-01

    In 1983, the Northwest Power Planning Council (Council) issued Model Conservation Standards (MCS) designed to improve the efficiency of electrically heated buildings. Since then, the standards have been adopted by numerous local governments and utilities. The Bonneville Power Administration (Bonneville) has played an active role in marketing residential energy efficiency improvements through the Super Good Cents Program (SGCP) and encouraging the adoption and implementation of the MCS as local codes through the Early Adopter Program (EAP). Since the inception of the MCS, however, questions have arisen about the effect of the code and programs on the selection of heating fuels for new homes. Recently, Bonneville has proposed a gradual reduction in the incentive levels under these two programs prior to 1995 based on several assumptions about the market for MCS homes: builder costs will decline as builders gain experience building them; buyers will seek out MCS homes as their appreciation for their lower energy costs and greater comfort increases; and the resale market will increasingly reflect the greater quality of MCS homes. The growing availability of data from several jurisdictions where the MCS have been implemented has recently made it possible to begin assessing the effect of the MCS programs on residential fuel choice and evaluating assumptions underlying the programs and Bonneville's plans to revise them. This study is the first such assessment conducted for Bonneville.

  4. Economic aspects of possible residential heating conservation

    Energy Technology Data Exchange (ETDEWEB)

    Hopkowicz, M.; Szul, A. [Technical Univ., Cracow (Poland)

    1995-12-31

    The paper presents methods of evaluation of energy and economy related effects of different actions aimed at conservation in residential buildings. It identifies also the method of selecting the most effective way of distribution funds assigned to weatherization as well as necessary improvements to be implemented within the heating node and the internal heating system of the building. The analysis of data gathered for four 11-stories high residential buildings of {open_quotes}Zeran{close_quotes} type being subject of the Conservation Demonstrative Project, included a differentiated scope of weatherization efforts and various actions aimed at system upgrading. Basing upon the discussion of the split of heat losses in a building as well as the established energy savings for numerous options of upgrading works, the main problem has been defined. It consists in optimal distribution of financial means for the discussed measures if the total amount of funds assigned for modifications is defined. The method based upon the principle of relative increments has been suggested. The economical and energy specifications of the building and its components, required for this method have also been elaborated. The application of this method allowed to define the suggested optimal scope of actions within the entire fund assigned for the comprehensive weatherization.

  5. Family Structure, Residential Mobility, and Environmental Inequality.

    Downey, Liam; Crowder, Kyle; Kemp, Robert J

    2017-04-01

    This study combines micro-level data on families with children from the Panel Study of Income Dynamics with neighborhood-level industrial hazard data from the Environmental Protection Agency and neighborhood-level U.S. census data to examine both the association between family structure and residential proximity to neighborhood pollution and the micro-level, residential mobility processes that contribute to differential pollution proximity across family types. Results indicate the existence of significant family structure differences in household proximity to industrial pollution in U.S. metropolitan areas between 1990 and 1999, with single-mother and single-father families experiencing neighborhood pollution levels that are on average 46% and 26% greater, respectively, than those experienced by two-parent families. Moreover, the pollution gap between single-mother and two-parent families persists with controls for household and neighborhood socioeconomic, sociodemographic, and race/ethnic characteristics. Examination of underlying migration patterns reveals that single-mother, single-father, and two-parent families are equally likely to move in response to pollution. However, mobile single-parent families move into neighborhoods with significantly higher pollution levels than do mobile two-parent families. Thus, family structure differences in pollution proximity are maintained more by these destination neighborhood differences than by family structure variations in the likelihood of moving out of polluted neighborhoods.

    Hampson, Neil B

    2011-01-01

    Although morbidity and mortality from accidental carbon monoxide (CO) poisoning are high in the United States, identification of common but poorly recognized sources should help prevention efforts. The study aimed to describe CO poisoning of home occupants due to a vehicle left running in an attached garage. News stories reporting incidents of US CO poisoning were collected daily from March 2007 to September 2009 via a news.Google.com search and data extracted. Patients were individuals reported in the media to have been poisoned with CO in their home by a vehicle running in the attached garage. Main outcome measures were frequency of occurrence, geographic distribution, patient demographics, and mortality. Of 837 CO poisoning incidents reported in US news media over 2 and a half years, 59 (8%) were the result of a vehicle left running in the garage. The elderly were disproportionately affected, with incidents most common in states with larger elderly populations and 29% of cases with age specified occurring in individuals older than 80 years. Among those older than 80 years, 15 of 17 were found dead at the scene. Residential CO poisoning from a vehicle running in the garage is common, disproportionately affects the elderly, has a high mortality rate, and should be preventable with a residential CO alarm.

    2017-10-01

    This data article relates to the research paper Energy consumption and efficiency technology measures in European non-residential buildings (D'Agostino et al., 2017) [1]. The reported data have been collected in the framework of the Green Building Programme that ran from 2006 to 2014. The project has encouraged the adoption of efficiency measures to boost energy savings in European non-residential buildings. Data focus on the one-thousand buildings that joined the Programme allowing to save around 985 GWh/year. The main requirement to join the Programme was the reduction of at least 25% primary energy consumption in a new or retrofitted building. Energy consumption before and after the renovation are provided for retrofitted buildings while, in new constructions, a building had to be designed using at least 25% less energy than requested by the country's building codes. The following data are linked within this article: energy consumption, absolute and relative savings related to primary energy, saving percentages, implemented efficiency measures and renewables. Further information is given about each building in relation to geometry, envelope, materials, lighting and systems.
