建筑节能的议题在当下越来越受重视,对于办公建筑而言,在单位面积各类围护结构中,通过外窗散失的能量是较多的,而合理的遮阳设计将能阻挡绝大部分的太阳直射辐射,降低外窗的能耗。笔者通过数值模拟的方法,对办公室南向外窗遮阳构件尺寸进行定量化模拟分析,使其满足室内光热环境的要求,以最大限度地降低能耗,并为遮阳构件与立面的整合设计提供参考。
The issue of building energy conservation in the moment more and more attention, for office buildings, in various types of envelope per unit area of the structure, the loss of energy through the window is more, and reasonable sunshade design will be able to block the vast majority The direct solar radiation, reduce the energy consumption of the outer window. By means of numerical simulation, the author quantitatively simulates the size of sun-shading members in the south-facing window of the office to meet the requirements of indoor light-heat environment so as to reduce energy consumption to the maximum extent and to design the integration of shading members and facades for reference.
