| Abstract |
In this study, dynamic heat load simulation was conducted according to apartment house's insolation absorptance and longwave emissivity of the exterior surface. This study analyzed heating and cooling load changes in relation to directions and regions. The main results are as follows. 1) In the insolation absorptance in Seoul, heating load decrease of about 9.00GJ/YR and cooling load increase of about 2.36GJ/YR was appeared and total load was decreased approximately 6.65GJ/YR on average for every increase of 10%. 2) Longwave emissivity in Seoul, heating load increase of about 0.42GJ/YR and cooling load decrease of about 0.13GJ/YR was appeared and total load was increased approximately 0.29GJ/YR on average for every increase of 10%. 3) By the direction of the building, heating load in Seoul was indicated high in the west, east and south in the order. In the insolation absorptance on average for every increase of 10%, heating load was decreased about 9.00GJ/YR per in the south, about 9.24GJ/YR per in the west and about 9.47GJ/YR per in the east. On the other hand, cooling load was indicated high in the east, west and south in the order. In the insolation absorptance on average for every increase of 10%, cooling load was increased about 2.36GJ/YR per in the south, about 2.72GJ/YR per in the east and about 2.77GJ/YR per in the west. |
