窗户对建筑能耗的影响研究

Study on the Effect of Window on Building Energy Consumption

窗户是建筑不可缺少的重要组成部分 ,也是建筑能耗的最大因素 .利用TRNSYS软件对建筑能耗进行模拟计算 ,分析了窗户的有关特性参数如透光率、窗墙比、窗台高和窗户朝向等对采暖和空调能耗的影响 ,验证了建筑东西向长、南北向短的节能特性 .

Window is an important part of building, and is al so one of critical factors affecting building energy consumption. Aiming at that, TRNSYS software is used for the simulation and calculation of building energy consumption. Analysis of the effect of window parameters such as transparency, window-to-wall ratio, sill and window orientation to heating and cooling energy consumption is carried out, and building geometrical character for energy savin g is validated to be right.
