本研究的目的是评估在炎热的天气期间,在伦敦住宅室内温度的变化,以及在何种程度上,这些住宅到住宅的变化解释的热特性的住宅和位置内的城市热岛(UHI)。在炎热的天气期间的室内温度进行了建模使用EnergyPlus模拟程序,作为输入数据的建筑特征的15个概念住宅原型广泛代表的伦敦住房存量,并在温暖的未来天气条件下在两个地点在伦敦内进行评估。关于住宅类型和特征的数据是从地理信息系统数据库、国家一级的国内建筑调查和其他来源确定的。外部天气数据来自英国气候影响计划(UKCIP)2002 - 2050年代中高排放情景下的伦敦站点特定气温模型。在不同的建筑形式中,室内温度有很大的差异。住宅的热质量有一个明显的更大的影响室内温度在“热”期间研究比城市热岛本身。建筑形式和其他居住特征的影响似乎是更重要的决定因素,在室内温度高的变化比伦敦的城市热岛内的住宅的位置。这一观察结果表明,旨在保护免受夏季高温的不利影响的政策可能需要更多地关注住宅设计和施工,而不是改善城市热岛。
The aim of this study was to assess variations in indoor temperatures in London dwellings during periods of hot weather, and the degree to which those dwelling-to-dwelling variations are explained by the thermal characteristics of the dwelling and location within the urban heat island (UHI). Indoor temperatures during periods of hot weather were modelled using the EnergyPlus simulation programme, taking as input data the building characteristics of 15 notional dwelling archetypes broadly representative of the London housing stock, and assessed under warm future weather conditions at two locations within London. Data on dwelling types and characteristics were determined from Geographic Information System databases, national level domestic building surveys and other sources. External weather data were derived from the London Site-Specific Air Temperature model under the UK Climate Impacts Programme (UKCIP) 2002 2050s Medium–High emissions scenario. There was substantial variation in indoor temperatures across built forms. The thermal quality of a dwelling has an appreciably greater effect on indoor temperatures during the ‘hot’ period studied than the UHI itself. The effects of built form and other dwelling characteristics appear to be more important determinants of variation in high indoor temperatures than the location of a dwelling within London’s UHI. This observation suggests that policies aimed at protection against the adverse effects of high summer temperatures may need to focus more on dwelling design and construction than on the amelioration of the UHI.
