일사유입면에 의한 바닥마감재가 난방부하에 미치는 영향에 관한 연구

This paper presents a study on influence upon heating load, paying special attention on the floor finishing materials for the Solar radiation surface. Nowadays, we are trying to reduce CO2 through the whole world, consumption of the buildings accounts for 35 percent of total energy consumption. The research on the alternative to reduce the heating load must be settled urgently because heating energy consumption makes up more than 50 percent of the buildings' consumption. The use of curtain-wall in buildings including offices is increasing rapidly, as high-rise buildings set the trend. Consequently, indoor floor surface is exposed to the Solar radiance. We analyzed indoor heating load through the change of the materials for the Solar radiance surface using VE(Virtual Environment) program. Materials for experiments are carpets, marble, timber and p-tiles. The difference between heating load with carpets and marble is 10.26 percent. That is materials with bigger capacity like marble are better to reduce heating load.
