Evaluation of Energy Efficiency and Thermal Performance for the Simplified Air-barrier System in Perimeter Zone

Because the perimeter of buildings is strongly influenced by solar and outdoor air temperature, the area has different environmental properties compared to the interior of a building, as in summer heat gain, and in winter heat loss. In particular, if the external wall is glass, the characteristics of the glass material make it pervious to outside conditions, thereby making big changes to the thermal environment. A simplified air barrier system is developed with the idea that energy could be conserved by carefully and effectively blowing out the air caught between the glass surface and the roller blind. It is configured by making the roller blind's air-path, and by placing the exhaust air ducts in the most optimum positions. This simplified air barrier system will improve the thermal environment and reduce cooling/heating load of the parameter area strongly affected by solar and outdoor conditions.
