不同典型气象年生成方法对建筑能耗的影响

Effect of several methods for generating typical meteorological year on building energy consumption

针对建筑能耗模拟用的Sandia,CSWD,CTYW,TPCY 4种典型气象年生成方法,选取典型城市西安,用相同的原始气象数据,取30a为周期,比较这几种方法生成典型气象年的差异及其对建筑能耗模拟结果的影响。结果表明:4种方法挑选出的典型气象年均优先选取前5项时,有重复出现,挑选出的典型气象年差异很小;CTYW方法挑选出的典型气象年模拟能耗最接近逐年模拟能耗,相对标准偏差为10.37%,其次是TPCY,CSWD,Sandia方法。

Researches the difference of the typical meteorological years （TMY） generated by four methods, namely Sandia, CSWD, CTYW and TPCY, and the effect on the simulation of the building energy consumption in Xi＇ an using the same meteorological data of thirty-year period. The results show that the selected TMY is repeated and the difference is very small when selecting the top five items as priority in the above four methods. The simulated energy consumption with the TMY selected by the CTYW method is the most close to the simulated energy consumption year by year, and the relative standard deviation is 10.37%, followed by TPCY, CSWD and Sandia methods.
