A Study on Cooling Energy Savings Potential in High-Rise Residential Complex using Cross Ventilated Double Skin Facade

摘要

The housing market in Korea is changing rapidly. As multi-functional high-rise residential complexes become popular, occupants need more comfortable indoor environment as well as more usable spaces than ever before. These trends force to increase the energy usage for environmental controls, especially for cooling. Thus, this study aims at reducing the cooling energy requirements of high-rise residential complex by maximizing the possibilities of natural ventilation strategies through cross ventilated Double Skin Facade. Based on ESP-r simulations, it was confirmed that the Double Skin Facade could reduce up to 30～40% of cooling energy compared to the conventional facade designs.
