中文摘要：

对北京市1栋普通住宅楼夏季空调能耗进行逐周调查分析，结果表明，目前北京市住宅空调器装得多、用得少，平均能耗水平较低，并且各住户空调能耗的差异很大、集中度很高，20％的空调能耗大户消耗了全楼约70％的空调能量。该楼空调能耗分布的基尼系数为0.64，因此空调运行模式是影响住宅空调能耗的最重要因素，住宅空调行为节能的潜力和“耗能”潜力均很大。

英文摘要：

Presents a weekly investigation result. Finds out that most of air conditioners in the building are functioned in a short period leading to relative low energy consumption level though there are so many room air conditioners equipped in the residential building. The difference of energy consumption among households in this building is quite large. Twenty percent of residents consume about seventy percent of the energy for cooling in the building. The Gini coefficient of energy consumption of air conditioners among households in this building is 0. 64. The operation mode of air conditioners is the most important factor impacting energy consumption in residential buildings. The increasing potential and the decreasing potential of energy consumption for cooling in residential buildings in China are great.
