摘要
本研究文章讨论了高性能外立面的设计方法，重点是减少热量传递和提高能源利用。外立面是任何建筑的能源预算和舒适度参数的最重要影响因素之一。在设计过程中必须考虑对物理环境因素的控制，包括减少热量传递的方法。高性能外立面需要阻挡不利的外部环境影响，并以最低的能耗维持内部舒适条件。
这项研究首先对四种不同的外墙类型（包括空心砖墙、陶土板幕墙、玻璃纤维增强混凝土板幕墙和幕墙）的传导热量传递进行建模，以比较它们的相对热性能。然后，对三个热性能改进的系统（包括带有隔热断桥框架的幕墙……）进行了热量传递建模。
AbstractThis research article discusses methods for designing high-performance facades with a focus on minimizing heat transfer and improving energy usage. The facade is one of the most significant contributors to the energy budget and comfort parameters of any building. Control of physical environmental factors, including methods for minimizing heat transfer, must be considered during the design process. High-performance facades need to block adverse external environmental effects and maintain internal comfort conditions with minimal energy consumption. The research was conducted by initially modelling conductive heat transfer in four different exterior wall types, including a brick cavity wall, a rain-screen facade with terracotta cladding, a rain-screen facade with glass fiber–reinforced concrete cladding, and a curtain wall, to compare their relative thermal performances. Then, heat-transfer modelling was conducted for three thermally improved systems, including curtain walls with thermally broken fra...
