    摘要:结合简单教学模型,利用Ecotect软件,针对建筑物理性能中的光、热性能进行仿真模拟分析。对于光环境分析,得出在进深较大的教学建筑中采取矩形天窗较有优势;通过设置不同窗墙比得到了与采光系数及达标面积之间关系。在窗墙比增加一定幅度基础上,通过达标面积率变化情况得到建筑采光得分变化。针对热环境,设置不同围护结构改造方案进行模拟,在以节能单方面考虑,改造外窗比改造外墙具有优势;但以节能为基础热舒适为目的,改造外墙比改造外窗具有优势。围护结构不仅影响节能,还会影响建筑室内环境,综合对比,得到相对最优围护结构方案。

    Abstract:Based on the simple teaching model and Ecotect software,the light and thermal properties of buildings are simulated and analyzed. For the analysis of light environment,it is concluded that rectangular skylight is superior in teaching buildings with large depth. The relationship between window-wall ratio and lighting coefficient and standard area is obtained by setting different window-wall ratio. On the basis of the increase of window-wall ratio,the change of building lighting score is obtained by the change of standard area rate. For thermal environments,setting different enclosure structure reconstruction schemes for simulation. In the unilateral consideration of energy saving,the transformation of outer window is superior to the reconstruction of external wall,but on the basis of energy saving and thermal comfort,the transformation of external wall is superior to the reconstruction of outer window. The enclosure structure not only affects the energy saving,but also affects the indoor environment of the building,by comprehensive comparison,the relatively optimal enclosure structure scheme is obtained.
    Key words:Ecotect,light and heat environment,building energy saving
