Study on structure heat capacity of high-rise residences (part 1) comparison with or without insulation

Here we examined Air-Conditioning loads (hereinafter referred to as AC loads) impact in several deferent cases of insulation methods in interior of super high-rise residences by using the dynamic simulation software "THERB"(the simulation software of Thermal Environment of Residential Buildings), which can estimate temperature, humidity, sensible temperature and heating/cooling load for multiple zones of buildings. The Proportion that structural frames, such as columns and beams of super high-rise residences, is larger than that of ordinary residences, and the skeleton is generally made of concrete and steel which have high heat storage capacity. Therefore the heat storage capacity of structure of super high-rise residences is considered to have larger effect on AC load than that of ordinary residences. So we consider that the AC load of super high-rise unit would be cut down by putting insulation on surface of interior walls, floors and ceilings on which usually insulation isn't put in Japanese buildings. Recently, high-rise residences are more and more important in our life with its rapid development in Japan. Therefore, reduction of energy consumption in high-rise residences is very important to reduce total environmental loads in Japan.
