High-rise Residences, Heat Insulation Method, AC Load,
Simulation, Heat Capacity
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.
