Comparative Study of Heat Transfer in Double Skin Facades on High-Rise Office Building in Jakarta

Article Preview

Abstract:

Building envelope on high-rise office buildings have an important role of energy consumed. There are many methods and techniques that can be used to achieve this goal through energy efficiency for building envelope in the tropic area. The use of glass material becomes one of the alternatives that offer a more attractive appearance. Although the double skin facades (DSF) has been widely applied, but research on the thermal performance and behavior of the wind is still scarce for the tropics, so it is interesting to note related to energy conservation. To obtain a clear picture of the heat transfer and airflow, the research was conducted on the two office buildings with the same orientation and location but they were different on the building envelope. The study was conducted by the field measurements and simulation using CFD-ACE + software, to determine the performance of the heat transfer and behavior of airflow in the double skin facades. The results indicate that the role of wind on the design building envelope has an influence on the heat transfer and energy savings. Key words: wind, double skin facade, heat transfer, CFD, energy
