高层建筑典型气象年数据竖直修正方法研究

Vertical correction method of typical meteorological year data for high-rise buildings

进行建筑能耗评估应考虑气象数据在竖直方向上的变化,目前的典型气象年(TMY)数据是基于地面观测数据获得的,无法很好地满足高层建筑的设计需求。本文基于上海宝山站的探空气象数据,提出了不同高度处TMY数据的修正方法,比较了修正后的TMY数据与实际气象数据的负荷模拟结果。结果表明:修正后的TMY数据的模拟结果与真实数据模拟结果的差异为3.65%~13.42%,且变化趋势一致;相较于地面观测处TMY数据的模拟结果,冷负荷准确度提高了2.37%,热负荷准确度提高了4.06%。

The change of meteorological data in the vertical direction should be taken into account in the evaluation of building energy consumption,and the current typical meteorological year(TMY)data are based on ground observation data,which can not well meet the design requirements of high-rise buildings.Based on the radiosonde meteorological data of Shanghai Baoshan Station,this paper puts forward a correction method of TMY data at different heights,and compares the load simulation results of the modified TMY data with those of the actual meteorological data.The results show that the difference between the simulation results of the modified TMY data and the real data is 3.65%to 13.42%,and the change trends are consistent.Compared with the simulation results of the TMY data at the ground observation,the accuracy of the cooling load and heating load simulation results of the modified TMY data is improved by 2.37%and 4.06%,respectively.
