A simplified model for estimating population-scale energy impacts of building envelope air tightening and mechanical ventilation retrofits

Changing the air exchange rate of a home affects the annual thermal conditioning energy. Large-scale changes to air exchange rates of the housing stock can significantly alter the residential sector's energy consumption. However, the complexity of existing residential energy models is a barrier to the accurate quantification of the impact of policy changes on a state or national level. The Incremental Ventilation Energy (IVE) model introduced here combines the output of simple air exchange models with a limited set of housing characteristics to estimate the associated change in energy demand of homes. The IVE model was designed specifically to enable modellers to use existing databases of housing characteristics to determine the impact of ventilation policy change on a population scale. The IVE model estimates of energy change when applied to US homes with limited parameterization are shown to be comparable to the estimates of a well-validated, complex residential energy model.     

Cost efficiency benchmarking of urban water supply utilities: The case of an Indian state

In most developing countries like India, benchmarking of water supply utilities is rarely carried out as these services are not run on professional lines to ensure profitability, even as social goals of making provision for all, including the poor, take priority over profitability. When performances of these services are not measured, efforts to improve these services remain directionless and arbitrary. Urban water supplies in India, therefore, suffer a self‐inflicted fate, wherein city municipalities remain mired in mundane issues, leading to large dissatisfaction and inefficiencies. This paper attempts to evolve a framework for evaluating cost efficiencies of water supply services and applies stochastic frontier analysis to 18 urban centres in India through six models. The results indicate large relative inefficiencies and a scope of savings of 24.5% of average current operating and maintenance costs even with existing levels of resource inputs. The results are discussed from a regulatory and policy‐making perspective.     

Breaking the cycle of homelessness: Housing stability and social support as predictors of long-term well-being

It is increasingly acknowledged that homelessness involves more than just being without a house. Indeed, more recent definitions of what constitutes a home highlight the role of social connections and support (including, for example, access to space to engage in social relations). This study examined the role of secure housing and social support as predictors of psychological well-being of individuals following a period of homelessness. Using linear mixed models for longitudinal data, we investigated how changes in social support predicted changes in individuals’ self-reported personal well-being, life satisfaction and mood following a period of homelessness (n = 119), controlling for housing status, alcohol use and employment status. The results showed that remaining homeless predicted poorer personal well-being, life satisfaction and mood. In addition, changes in social support predicted well-being over and above housing stability. Implications of findings for policy and practice in the homeless sector are discussed.     

城市设计与城市更新:英国经验及其对中国的镜鉴

中国城市化率突破50％之后,城市更新成为城市发展的重点;城市设计作为控制城市空间形态的公共政策,面临新的挑战与需求.回顾了英国城市更新的主要挑战:去工业化与内城衰败、郊区化与边缘城市、全球化与城市竞争;城市设计作为英国的国家政策之一,通过推动消费及创意产业发展、内城再美化、郊区产业及形态多样化、塑造建筑与场所标志性及促进城市营销等策略,对英国的城市更新进行了全方位的推动.中国城市正面临迫切的城市更新的挑战,既有的城市设计实践范式也面临深刻的危机.英国经验为中国提供了批判性的镜鉴:城市设计应该成为综合性的城市更新战略的一部分、必须建立系统化的城市设计政策框架、城市设计对城市更新具有两面性等.

城市综合管廊投融资模式探讨

随着城市综合管廊建设的全面推动,单纯依靠政府投资的模式显然难以为继,资金问题成为阻碍其大规模发展的瓶颈。通过对比国内外综合管廊投融资情况,结合综合管廊的经济属性和国内相关政策环境,设计出管线单位参与投资、政府与社会资本联合投资、社会资本投资和政府补贴三种投融资模式,并提出相应的保障措施,以供城市综合管廊建设参考。     

Consequences of large customer opt-out: An Ohio example

Opt-out policies allow large customers to withdraw from participation in utility sector efficiency programs. Our analysis shows these policies impose high costs, including increased utility system investments due to higher demand, increased air pollution within the state and surrounding regions, higher health costs because of the increased air pollution, and lost bill savings opportunities for large customers, leading to lost economic growth. We examine the consequences using Ohio as an example.     

Effect of regulation on power-plant operation and investment in the South East Europe Market: An analysis of two cases

This paper analyses the differences between investment decisions for coal-fired power plants in Croatia and in Bosnia and Herzegovina (BiH). The long-run marginal cost (LRMC) of each plant is calculated based on a technical analysis that accounts for the important influences on overall project costs by combining a mathematical model and a simulation model. The former was used to calculate annual costs and the latter to predict power plant performance on the electricity market. This research offers insights about potential risks associated with power-plant investment with a particular focus on the regulatory framework and the relevance of participation in the European Union Emissions Trading Scheme (EU ETS) for costs, prices, and environmental impacts.     

Understanding the New Zealand non-domestic building stock

Unlike the residential building stock, most countries have poor information on their non-domestic stock. This necessitates the use of other data sources. In the mid-1980s the (then) New Zealand Department of Valuation digitized its valuation records. This permitted the first analysis of an entire country's non-domestic buildings. A very long-tail probability density function was identified, with the largest 5% of buildings containing more than 40% of the floor space. This knowledge informed the development of research for understanding non-domestic buildings as well as underpinning the 1996 revision of the NZ Building Code Clause H1 Energy Efficiency. More recently an analysis of valuation data has provided the Building Energy End-use Study (BEES) with a national sampling frame to examine energy and water end-uses in non-domestic buildings. The development of processes for collecting and analyzing data is described. Considerable changes in understanding of valuation data have occurred for documenting the non-domestic building stock. New online and geographic information sources can validate and improve building data. The use of such a database supports improved understanding of the changing nature of the building stock and potential intervention points, as well as harnessing regulatory and market forces.
