摘要
针对采光系数仅能表征阴天采光状况的局限性,运用采光时序图,结合典型时段的采光数值计算,探索适用于中国学校作息时间的教室全年采光评价方法。基于重庆地区的实地调研,结合Kleindiens提出的"相似时段"分析法,将全年划分为72个典型时段,运用Perez天空模型、TMY2逐时气象数据得到典型时段的桌面采光平均值及空间采光达标率,可为采光改进、健康照明研究提供基础数据。
In view of the limitation that the daylighting coefficient can only represent the daylighting condition in cloudy days,a set of evaluation method of classroom daylighting suitable for school work and rest time in China is explored by using the lighting sequence diagram and combining with the daylighting numerical calculation of typical periods.Based on the field survey in Chongqing,combined with the"similar period"analysis method proposed by kleindiens,the whole year is divided into 72 typical periods.The average desktop lighting and the spatial lighting standard rate are obtained by using Perez sky model and TMY2 hourly meteorological data.It can provide comprehensive basic data for reasonable lighting improvement and healthy lighting research.
