단독주택의 창호 면적 변화에 따른 열 획득 및 열 손실에 관한 연구

Window is the most demanding design component in the building design. Wndow is related to the heat loss and heat gain. Therefore we need to find out optimal point by the window area for the best thermal performance. In this paper, we discussed the energy consumtion of the rural standard house according to window area. Two types of window is used for the simulation. And analysis is performed using PHPP 2007(Passive House Planning Package) program adopting the monthly calculation method of ISO 13790 as a calculation algorithm. As a result, it has been identified that there is negative correlation between window area and annual heat demand. That is, the annual heat demand has been decreased as window area increased. And two types of model has different correlation coefficient.
