广州市城镇住宅用能行为特征聚类及其对用能需求的影响
Clustering analysis of occupant behavior and its impacts on energy demand of urban residential buildings in Guangzhou
摘要:
针对当前城镇住宅用能需求研究中缺少对住户用能行为差异性考虑的现状,以广州市城镇住宅为研究对象,根据问卷调研和聚类分析,提炼得到用能需求较高(B1)、用能需求中等(B2)和用能需求较低(B3)3种典型用能行为模式,并使用DesignBuilder能耗模拟软件进行用能需求模拟。结果表明,广州市城镇住宅居民用能行为模式存在较大差异,住户用能方式的多样化直接导致了户均用能需求差异巨大。B1、B2和B3模式下全年户均用能需求分别为36~49、31~41、25~33 GJ。
Abstract:
In response to the current situation that the study of urban residential energy demand lacks consideration of the differences in energy consumption behavior of occupants, urban residential buildings in Guangzhou are used as the research object. This study generates three typical occupant behavior patterns of high energy demand (B1), medium energy demand (B2) and low energy demand (B3) on the energy use of urban residential buildings in Guangzhou with questionnaire surveys and clustering analysis, and figures out its impacts on energy demand by using DesignBuilder software. The results show that there is great diversification in the behavior patterns of energy use among urban residents in Guangzhou, which directly leads to large differences in energy demand among households. The annual average household energy demand under the B1, B2, and B3 models is 36~49, 31~41, and 25~33 GJ.
