To achieve CO2 emissions reductions, the UK Building Regulations require developers of new residential buildings to calculate expected CO2 emissions arising from their energy consumption using a methodology such as Standard Assessment Procedure (SAP 2005) or, more recently SAP 2009. SAP encompasses all domestic heat consumption and a limited proportion of the electricity consumption. However, these calculations are rarely verified with real energy consumption and related CO2 emissions. This work presents the results of an analysis based on weekly heat demand data for more than 200 individual fiats. The data were collected from a recently built residential development connected to a district heating network. A method for separating out the domestic hot water (DHW) use and space heating (SH) demand has been developed and these values are compared to the demand calculated using SAP 2005 and SAP 2009 methodologies. The analysis also shows the variation in DHW and SH consumption with size of flats and with tenure (privately owned or social housing). Evaluation of the space heating consumption also includes an estimate of the heating degree day (HDD) base temperature for each block of fiats and compares this to the average base temperature calculated using the SAP 2005 methodology. 展开更多

SUA (space-use analysis) is about techniques that objectively describe environments and relate this description to specific problems of use. The purpose of this paper is to explore a space-use analytical tool--POE (post-occupation evaluation)--regarding a neighborhood accessibility condition. Based on a site-specific approach, the main research question is focused on how far neighborhood walking paths are compatible with different user needs, guaranteeing their safety and autonomy, as well as easiness of perception and use, thus providing access to local services and resources they need for participation in the day-to-day activities of community life. This paper is organized in three parts: The first one introduces the main concepts and explains how to ensure it in a practical application in urban design; The second part presents the practical approach, referring to the used methodology, the specific case-study and reached results; The third one establishes correlations between the two approaches and discusses the main findings. 展开更多
