| Abstract | The use of glazed fa?ades for office buildings in Phnom Penh city has been increasing these days, and those conventional fa?ades lead to a high energy demand especially for cooling purpose in the buildings. Almost fifty percent of the overall annual energy has been consumed by the commercial sector in Cambodia, and it keeps growing year after year. Pertaining to the matter, the use of double skin fa?ade (DSF) as one of the approaches to improve building energy performance has been studied. The objectives of this study are, to assess the potential of DSFs on building energy efficiency, and to propose its optimum configurations for office buildings in Phnom Penh city. To do so, the different DSF parameters consisted of cavity depth, glass materials for interior and exterior layer and shading device for DSFs were investigated by using the whole building energy simulation program, EnergyPlusTM. The primary result shows that DSF is a good technique to achieve building energy efficiency in Phnom Penh city, but it does require a proper design to avoid unexpected issues such as excessive solar radiation and thermal transfer into the building through the building's fa?ade. The optimum parameters of DSF found in the study are 500 mm cavity depth, bronze laminated glass for the internal, and external layers of DSF, and external blind louvre. The combination of all optimum parameters could potentially reduce about 34% of the annual energy demand. |
