基于粗糙集的夏热冬暖地区建筑能耗关键指标识别研究

Research on The Recognition of Building Energy Consumption Indexs of Region with Hot Summer and Warm Winter Based on Rough Set

对建筑能耗关键指标识别是建筑节能的基础,是进行建筑能耗预测和正确决策的前提。采用文献研究法、专家调查法对住宅建筑能耗指标进行分类,即能源种类指标、能源驱动因素指标、能源用途(能源消耗终端种类)指标。基于粗糙集理论,采用Johnson算法,利用Rosetta软件对建筑能耗关键指标进行识别。结果显示,煤、电、石油液化气、可再生能源是目前建筑能耗中主要的4种能源。人均GDP、人口总量、建筑面积是建筑能耗的主要驱动因素,家用电器、空调、炊事、照明是建筑能耗的主要因素。

To identify the indexes of building energy consumption is the basis for building energy Saving and correct decisions. residential building energy consumption indicators are classified with Literature research,expert investigation method.Based on rough set theory,Johnson algorithm,using Rosetta software for building energy consumption to identify key indicators. The results show that coal,electricity,liquefied petroleum gas,renewable energy is currently building four major energy consumption. Per capita GDP,the total population,the building area is the main driving factor of building energy consumption,household appliances,air conditioning,cooking,lighting is a major factor in building energy consumption.
