摘　　要：人工照明系统用电占到了全世界电能消耗的19%,采用自然采光替代人工照明被认为是可持续建筑设计中有效手段之一。新版《建筑采光设计标准》(GB 50033—2013)相比旧版有较大的修订,给出了新的采光设计与采光节能的设计指标和计算方法。本文以重庆某综合体绿色建筑为例,分别采用照明仿真软件Relux和GB50033提供的公式,对其教室部分的自然采光及节能潜力加以分析。结果表明,当采用了较复杂的窗型与遮阳设计方案时,Relux能得到更为精确的自然采光分析结果。最后对采光照明节能计算仿真软件的改进方向提出了建议。Artificial lighting makes up 19% of electrical consumption worldwide. Daylight has been recognized as a free energy and cost effective alternative to artificial lighting for sustainable building design the new version Standard for Daylighting Design of Buildings （GB50033） has fully revised the original standard, which presents new metrics and methods for indoor daylight availability assessment, as well as estimation methods used for predicting potential energy saving from daylight. A case study of a newly constructed educational building in the LEU, Chongqing, is presented. Computational analysis using validated lighting simulation tool Relux and formulas in GB50033 standard will be conducted to simulate the daylighting performance in the selected classroom. The results show that using the RELUX simulation tools have more accurate results than using the formulas of standard when the complex windows and sunshade model was adopted. Finally, the current limitations of tools and processes and propose future developments were described.
