Study on the thermal performance of double-skin facade

Abstract

Double-skin façade is a technique covered with glasses the building exterior, it can realize energy saving as well as highly transparent façade. From these perspectives, the installation of double-skin façade for office building has increased in recent years. The design of the recent focus on life cycle assessment needs annual or seasonal performance characteristic for the double-skin facade as well as a performance characteristic on peak load. In this study, the thermal performance of double-skin façade was described by using field measurements survey and simulation results. Solar shading coefficient (SC) value and thermal transmission (U) value can describe solar heat gain of double-skin façade. The prediction method for SC value and U value was introduced, can predict the thermal performance considering the seasonal fluctuation.
