摘要
受太阳辐射来向逐时变化的影响,建筑遮阳效果与遮阳设计计算时段密切相关。要实现良好的建筑遮阳设计效果,就需要依据室外气候条件、室内设计基准、围护结构构造、房间运行方式来准确确定遮阳计算时段及相应的室外计算参数。本研究根据建筑遮阳设计目标的不同,明确了3种遮阳计算时段的判定条件,并提出"必须"、"应"、"宜"3个等级的遮阳设计要求;提出了基于室内热环境需求的遮阳计算时段起止时刻确定方法,并给出了一个简单算例,得到了夏热冬冷地区5个典型城市简化房间模型下的建筑遮阳设计室外计算参数。该研究可为建筑热工体系的发展及建筑节能基础数据体系的建立提供支撑。
Influenced by the temporal variation of solar radiation,the shading design effect of buildings is closely related to the design period.In order to achieve good shading design effect,it is necessary to accurately determine the shading design period and corresponding outdoor design conditions according to outdoor climate conditions,indoor design standards,envelopes structure and room operation mode.This study clarifies the determination conditions of three shading design periods,according to the different design objectives of sun shading,and put forward the three levels of shading design requirements of"must","should"and"appropriate".This research proposes a method to determine the starting and ending time of shading design period based on indoor thermal environment requirements,and obtains outdoor design conditions of sun shading design of 5 typical cities in the hot summer and cold winter zone.This study considers the demand of design conditions for the development of building thermal design system,providing support for the establishment of building energy conservation basic data system in China.
