中国住宅建筑使用阶段碳排放的因素分解实证

根据住宅建筑碳排放的特点,通过完善和扩展Kaya公式,引入对数平均分解指数法,提出住宅建筑使用阶段碳排放因素分解的实证模型.根据1995—2008年中国建筑能源消耗的统计数据,分析居民消费水平、能源结构、能源消费强度、户均建筑面积、人口密度等因素对住宅建筑使用阶段碳排放变化的影响,提出住宅建筑使用阶段碳排放的正向驱动和负向驱动因素及其规律,为控制建筑节能提供建议.

An Empirical Discussion on Factorial Decomposition of Carbon Emission from Chinese Residential Buildings During Operation

In order to analyze patterns of carbon dioxide emission from houses, an empirical model is proposed for decomposition of factors which influences carbon emissions from post occupancy of houses based on the optimization and expandetion of Kaya equation, and the modification of logarithmic mean divisia index. The factors of consumption level, energy structure, energy consumption intensity, household size and population density are discussed from Chinese statistic data of building energy consumption from 1995 to 2008. The factors of accelerating the growth of carbon emissions, and restraining the carbon emissions, are presented as well as carbon emission tendency. Several feasible proposals to control carbon emission from houses are also discussed in the end.
