随着中国城市化进程的推进，建筑物的减排问题日益突出。根据最新数据，我们估计了中国的建筑物总面积，住房总面积和住宅电梯存量。同时，我们还估算了建筑运营阶段化石燃料的能源消耗和碳排放。对城市居民碳排放和排放强度的变化进行了两个指标分解分析。研究结果表明：1996-2012年，我国城镇居民生活能源消费由一次能源消费向电力和热力消费转变，直接排放的CO2占居民生活排放的比重下降。其次，居民能源强度、人均住房面积、家庭总户数是影响碳排放变化的主要驱动因素，贡献率分别为-39%、77%、67%，其中能源强度下降是碳强度下降的最主要因素（贡献率为89%）。第三，碳强度的降低有利于CO2的下降和城市住宅排放强度的降低。最后总结了研究期间对经济和社会政策反思的住宅节能政策经验教训。(C)2016爱思唯尔有限公司版权所有。
With China's urbanization, issues relating to emission reduction of buildings have become more prominent. Based on the latest data, we estimate total area of China's buildings, total housing area, and residential elevator stock. And also, we estimate energy consumption and carbon emission from the fossil fuel during building operation phase. Two index decomposition analysis on changes of urban residential carbon emissions and emissions intensity have been applied. The major findings of the study are: firstly, there has been a significant shift from primary energy consumption to electricity and heat in urban residential during the periods of 1996-2012, and the proportion of direct CO2 emission to residential emission declined. Secondly, residential energy intensity, per capita housing area, total number of households are the main driving factors affecting the change in carbon emissions, with contribution rates of -39%, 77%, 67% respectively, and the decline of energy intensity is the most important factor of decreasing carbon intensity (contribution rate of 89%). Thirdly, reduction of carbon intensity is conducive to the decline of CO2 and decrease in emission intensity of urban residential. Residential energy efficiency policy lessons learned from rethink of economic and social policies during the study period were concluded finally. (C) 2016 Elsevier Ltd. All rights reserved.
