南外窗百叶遮阳对冬季建筑能耗影响的数值模拟

Numerical Simulation of Southern Window-shades' Influence on Winter Building Energy Consumption

根据我国的地理位置和建筑朝向特点,一般建筑通常是南向窗户占墙的比例最大。由于现代建筑追求美观和欣赏功能,玻璃窗占墙的面积也是越来越大。所以建筑南向窗户的节能变的不容忽视,既要考虑夏季遮阳,也要考虑冬季保温。本文就通过Ecotect软件模拟,分析南向外窗在设置水平百叶固定外遮阳的情况下,百叶角度对冬季南向外窗的节能影响。

According to geographical location and building orientation in our country, it is a bigger percentage of south window in a common building. Due to the modem architecture pursuit of aesthetics and appreciation functions, Glass Windows＇ area of the wall is also increasing. So energy saving of south window in building should not be ignored, we both want to consider the summer sunshade and the winter heat preservation. This article analyze the horizontal fixed window-shades＇ angle influence on winter building energy consumption by ecological building great master software named Ecotect.
