基于DeST典型年数据的建筑采光实验模拟研究

Simulation Study of Architectural Lighting Experiment Based on the Data of DeST Typical Year

近年,在建筑采光研究及相关应用中,典型年数据的使用越来越普遍,由于不同的数据开发者所采用的思路及方法也存在差异,不仅会直接影响建筑采光模拟结果的精确度,而且在典型年数据更新周期内,城市气候可能会发生短期、随机、显著的变化,DeST典型年数据难以满足全年逐时(甚至逐分)的动态采光研究的需要。针对这些情况,本文以天津实测太阳辐射数据为参考,通过典型年修正数据的实验模拟和实测采光数据的实验模拟数据对比,对DeST典型年数据在天津地区的适用性进行研究。

In recent years,the use of typical annual data has become more and more common in architectural lighting research and related applications.Due to the differences in ideas and methods adopted by different data developers,it will directly affect the accuracy of architectural lighting simulation results,and in the typical annual data update cycle,urban climate may undergo short-term,random,and significant changes.The typical annual data of DeST is difficult to meet the needs of dynamic daylighting research on a time-by-hour(or even minute-by-minute)basis.In view of these situations,this paper takes the measured solar radiation data of Tianjin as a reference,and compares the experimental data of typical annual correction data with the experimental data of actual measured lighting data to study the applicability of DeST typical annual data in Tianjin.
