北京市建筑能耗统计误差来源分析

Source of statistical error of building energy consumption in Beijing

针对北京市建筑能耗统计数据,分析了统计误差对建筑能耗数据的影响,认为统计数据误差的主要来源是建筑总能耗对应的热力系统和相应的边界不统一,建筑能耗计量器具不统一,建筑能耗折算方法不统一及统计样本数量不足等。研究了样本建筑数量对能耗统计结果的影响,给出了北京市各类建筑合理的样本建筑数量。

Based on the statistic data from the energy consumption of buildings in Beijing, analyses the effect of statistical error on energy consumption data of buildings. Puts forward the main sources of statistical data error, i.e. dissimilarity between thermodynamic system corresponding to total building energy consumption and relevant boundary, inconsistent metering devices for building energy consumption, un-united converting way for building energy consumption and insufficient number of statistic samples. Discusses the effect of building sample number on statistic result. Proposes the reasonable quantity of building samples for various buildings in Beijing.
