Abstract This study is focused on analysis of the characteristics of thermal load using dynamic heat load simulation according to building exterior thermal performance and direction classified by each household in apartment house. The conclusion of the study is as follows. 1) The characteristics of thermal load classified by each household in a view of the story showed that the mean heating and cooling load at the top floor was the highest(371MJ/㎡yr), the second highest at the ground floor(339MJ/㎡yr) and the lowest at the center floor(281MJ/㎡yr). The heating load of each household in the same story was increased by 10%(side wall of center floor)∼52%(side wall of ground floor) than the center household of center floor which has the lowest in heating load. In the case of cooling load small change occurred except the ground floor. 2) As a result of investigating the characteristics of thermal load according to the change of direction, apartment block which has 25th floor and one hundred of household showed that the south(232MJ/㎡yr) was the most advantageous direction for heating load and the northeast(290MJ/㎡yr) was the most disadvantageous. In the case of cooling load, the south and north(51MJ/㎡yr) was the most advantageous direction and the east(63MJ/㎡yr) was the most disadvantageous. 3) As improving building exterior thermal performance by 10% against the legal standards of building, the mean heating load of one hundred household showed a increased by 22∼23MJ/㎡yr as the mean thermal disadvantage factor was increased by 0.1W/㎡K. Mean heating load and the mean thermal disadvantage factor showed liner correlations. As improving building exterior thermal performance, the mean cooling load of one hundred household showed a constant pattern.
