基于LCA的上海典型办公建筑窗墙比及窗户材料优化配置

LCA-based Optimization of Window-wall Ratio and Window Materials of Typical Office Building in Shanghai

本文以上海某办公楼建筑为研究对象,采用建筑物生命周期评价方法研究分析几种窗户类型下各个朝向的窗墙比对建筑生命周期评价结果的影响规律。结果表明,普通窗户的窗墙比对建筑生命周期评价结果影响较大,中空窗或Low-E中空窗的影响不大,同时优化窗户材料比控制窗墙比对改善建筑生命周期环境影响更为有效。

In this paper, taking an office building in Shanghai as the research object, the method of LCA was used to study the influences of window-wall ratio on environment, the detailed analysis included different orientations and different window types. The results indicated that the window-wall ratio of common type window had greater impact on the assessment than that of the hollow glass window and Low- E hollow glass window. Furthermore, in order to improve the influence of building life-cycle on environment, optimizing the window materials was more effective than controlling the window-wall ratio.
