THERMAL PERFORMANCE OF GLASS CURTAIN WALLS WITH THERMAL BREAK FRAMING SYSTEM

Abstract

In order to reduce the energy consumption of buildings and improve the resistance of aluminum framing members to condensation, the glass curtain walls with thermal break framing system are very important. However this framing system has barely been utilized in Japanese buildings. In this paper, we proposed the idea that glass curtain walls with both fins shading solar radiation and a thermal break framing system are suitable for buildings in the warm regions of Japan. Calculating results for the heat load confirmed that this idea has obvious benefits of improving the thermal performance and reducing the energy consumption.
