Simulation and analysis of thermal performance of external respiration double skin facade

Simulates and analyses the velocity and temperature fields inside the external respiration double skin facade of a building. Discusses the influences of the shading and airspace width on the integrated heat transfer coefficient. Compares the heating and cooling energy consumption of buildings applying external respiration double skin facade with that of buildings applying four single glazing curtain walls. The results show that the external respiration double skin facade has a superior energy efficiency potential and is one of the ecological building envelops.
