                摘要:

                    基于目前北京市公共建筑电耗现状及限额制定方法的分析,提出了“制定定额”“限额与定额相结合”及“限额与定额相结合基础上补充定额”3种电耗限额制定优化方案。其中,定额采用基于大量实测数据的统计分析法确定,限额则以建筑自身历史数据为基准确定。探讨了定额制定过程中异常值剔除、样本正态性检验等所用方法,并比较了所得定额值与全国约束值。基于对公共建筑电耗历年波动情况的统计分析,探讨了定额和限额水平的取值。经过3种方案考核结果的对比,提出了对北京市公共建筑电耗限额制定方法的建议。

                Abstract:

                    Based on the analysis of the current electricity consumption and the limit calculation methods of public buildings in Beijing, proposes three approaches to modify the limit calculation methods, namely, using quota, limit and quota combination, and another quota on the base of limit and quota combination. The quota is determined by a statistical analysis method based on large amount of measured data, while the limit is determined by the building’s historical electricity consumption data. During the calculation, discusses the methods of outlier detection and normality test of sample distribution, and compares the quotas with the constraint values in the national standard. Moreover, discusses the values of quota and limit levels based on the statistical analysis on the fluctuation of public buildings’ historical electricity consumption. After comparing the results of the three schemes, puts forward the suggestion for the calculation method of building electricity consumption limit.
