Abstract

Glazed curtain wall systems have become indispensable particularly in office buildings due to their light weight, aesthetic appearance, easy installation and resistance to climate conditions. Curtain walls however, also have problems in terms of thermal efficiency because of their wide, glazing windows and metal frames that have high thermal conductivity. The aim of this study is to offer proposals for improving the thermal performance of an office building with a glass curtain wall system built in a hot-humid climate zone. An office building constructed in Antalya, Turkey was modelled with the help of DesignBuilder energy simulation software and various modifications were made on the model in order to improve the thermal performance of the building. With the improvements proposed in the study, it is possible to decrease the annual thermal loads of the whole building by 6.6%, and the annual thermal loads of the space with the curtain wall by 33.2%. The study revealed that, applying an additional envelope is more effective than lowering the U-value of the glass of the curtain wall in terms of thermal performance improvement.

基于玻璃幕墙改造的办公楼热工性能改善建议

玻璃幕墙系统由于其重量轻、外观美观、易于安装和耐气候条件而变得不可或缺，尤其是在办公楼中。然而，幕墙在热效率方面也存在问题，因为它们的宽玻璃窗和具有高导热性的金属框架。本研究的目的是为改善湿热气候区玻璃幕墙办公楼的热性能提供建议。在DesignBuilder能源模拟软件的帮助下，对土耳其安塔利亚建造的一栋办公楼进行了建模，并对模型进行了各种修改，以提高建筑的热性能。通过研究提出的改进措施，可以使整个建筑的年热负荷降低6.6%，带幕墙的空间的年热载荷降低33.2%。研究表明，在热性能改善方面，应用额外的围护结构比降低幕墙玻璃的U值更有效。
