典型气象年和非典型气象年在建筑节能设计中的应用研究

Application of Typical Meteorological Years and Untypical Meteorological Years in Building Energy Consumption Simulation

采用Sandia实验室方法挑选出5个热工设计分区代表城市的典型气象年数据,以及4个类型(V;、V;、V;、V;)的非典型气象年数据,对各区代表城市的典型办公建筑进行能耗模拟,分析平均能耗和峰值能耗;同时计算建筑被动式设计策略的有效时间比,分析不同类型UMY的自然通风及被动式太阳能采暖有效时间比的计算结果。模拟结果表明,V;类型的非典型气象年对严寒、寒冷、夏热冬冷3个地区的供暖能耗峰值分析具有重要价值,而对于制冷能耗峰值,则需根据具体城市进一步分析。在自然通风设计策略的有效时间比计算结果中,V;类型的UMY有效时间最少,而被动式太阳能采暖设计策略的有效时间比的最低计算值在不同地区出现在不同类型的UMY中。对补充完善典型气象年的平均能耗评估,定量、全面地分析建筑能耗及建筑被动式设计策略具有重要参考价值。

The Sandia laboratory method is used to select the typical meteorological year data of five thermal design zones representing cities and the untypical meteorological year data of four types(V;,V;,V;,V;).The energy consumption of typical office buildings in each district is simulated,and the average energy consumption and peak energy consumption are analysed.The experimental results show that the V;type untypical meteorological year is of great value to the peak analysis of heating energy consumption in the three areas of severe cold,cold,and hot in summer and cold in winter,while the peak energy consumption of refrigeration needs to be further analysed according to the specific city.This study has important reference value for supplement and improvement of average energy consumption assessment of typical meteorological years and quantitative and comprehensive analysis of building energy consumption.
