Research on Heat Load Reduction of Steel Frame Houses by using Heavyweight Steel Frame as Thermal Mass —— Measurement Results of Summer
Steel frame houses are generally considered to be environment-unfriendly due to the problem of heat-bridge effect of steel. But if the high heat capacity of the steel frame of the building structure is considered, it can play a role of heating element making it possible to decrease the air conditioning energy load. In summer, it is possible to reduce the air conditioning load from morning to afternoon by storing coolness in high heat-capacity steel frame of the building structure through fetching in the cold air of night time by undertaking night-purge. Also, in winter there are methods of reducing heating load by storing the heat during day time by solar insolation and by dissipating the stored heat from evening to night time when heating demand (heat load) of the residence is generally high. In this research, an experiment was conducted, where the heat was stored in the heavy weight steel frame of an independent residence and its contribution to heat load reduction was measured and analyzed. Moreover, system for using the building frame as heat storage body was developed and whether it effectively leads to heat load reduction was analyzed by simulation.
