浅谈被动式建筑外窗

Discussion on Exterior Windows of Passive Buildings

被动式建筑外窗是实现被动式建筑的先决条件,所以必须从门窗设计、材料选择、加工生产、节点处理、成窗安装方面予以重视。本文从降低建筑外窗的传热系数和保证气密性的角度,进行了分析和建议。其中,外窗型材、玻璃技术和暖边条技术是影响建筑外窗的三大要素。正是如此,严苛的细节把控才使其可以安装在被动式建筑上,达到被动式建筑整体的被动式效果。

Passive exterior windows is the prerequisite to realize passive building,so we must pay attention to the design of doors and windows,the selection of materials,the processing and production,the treatment of nodes and the installation of finished windows.In this paper,from the point of view of reducing the heat transfer coefficient and ensuring the air tightness of the building's exterior windows,the analysis and suggestions are made.Among them,the window profile,glass technology and warm edge technology are the three factors that affect the exterior windows.It is such strict details control that passive exterior windows can be installed to achieve the overall passive effect of the whole building.
