厦门大学2013SD参赛作品建筑遮阳模拟分析

Abstract

建筑外门窗是建筑围护结构的重要组成部分,也是建筑热量损失与接收的薄弱环节。外窗不仅是建筑在采光通风功能上的需要,也是人与外环境沟通必不可少的通道。建筑遮阳是提高门窗在建筑围护中的热工性能的重要途径。结合ECOTECT软件与厦门大学参加2013年国际太阳能竞赛(SOlAr dECATHlOn)的参赛方案,探讨了建筑遮阳对室内热环境的影响,以及不同形式遮阳对太阳辐射热的遮挡效果的差异。

Doors and windows are important components of building envelopes, which are also the weak parts of the heat loss and receiving.The window is not only the needs of the lighting and ventilation, but also the essential channel for communicating with external environment.Architectural shading is a crucial way to improve the thermal performance of windows and doors in the building envelope.Combining software Ecotect with the scheme of Xiamen University's entries in Solar Decathlon China 2013, the shading effects on indoor thermal environment are expounded, as well as the shielding effect of various forms of shading on solar radiation.
