摘要(Abstract):

本文利用IES建筑性能集成化分析软件,对具有封闭采光中庭的天津某大进深农村住宅的采光进行了数值模拟、分析与优化研究。利用数值模拟的手段,将该住宅采用采光中庭前后的采光系数进行了比对分析。分析结果表明,利用采光中庭能够有效提高该住宅中部以及北向主要使用房间的采光效果,主要使用房间的采光系数值比未采用采光中庭时提高约70%。同时,针对该住宅的特点,对采光中庭及北向主要使用房间的采光口进行了优化设计及数值模拟分析。分析结果表明,在不改变采光口面积的前提下,采用平天窗形式的采光中庭具有更好的采光效果:中部及北向主要使用房间的采光系数值提高了约30%。
In this paper,numerical simulation on daylighting of a rural residential building with closed atrium was introduced and daylignting factor of rooms in the building was analyzed by using IES Virtual Environment software.Simulating results show that the atrium has great contribution to the daylighting of rooms in middle of the building.The optimization of daylighting openings in atrium and northern rooms was also introduced in this paper.Optimizing results show that the daylighting factor of rooms in middle of the building increased 30% by using skylight in the atrium.
