일사실내유입면의 바닥마감재가 냉방부하에 미치는 영향에 관한 연구

Curtain wall structure of office buildings has an advantageous aspect to improve lighting efficiency and to secure openness and transparency. But thermal comfort for occupants makes worse because of direct sunlight. So, our study goal is comparison and analysis of cooling load for curtain wall structure of office buildings following kinds of finishing materials for the solar radiance surfaces. And then we are after doing study on influences upon cooling load to the finishing materials. A universal finishing materials such as Carpet, Marble, Timber and Plastic tile are set up variables. And indirect solar radiance surfaces is fixed Carpet. After that we investigated windows adapting curtain wall structure of office buildings. Findings on investigation, There are Double glazing window and Double glazing with Low-e window. So we also analyzed cooling load together with following each windows. This study arrive at a conclusion. Finishing materials for the solar radiance surface should be used having good performance of heat storage like Marble. Also adapting window for curtain wall structure of office building is an important factor for reducing cooling load.
