주광조명제어의 건물최대냉방부하 감소효과에 주광조명가능면적비가 미치는 영향에 대한 해석적 연구

The objective of this paper is to investigate the relation between daylight-induced peak cooling load saving and daylight area ratio in a medium office building. The first step to achieve for this purpose is building energy simulation. We used DOE-2, energy simulation program, to demonstrate the energy performance of several midium sized office building. 56 simulation results were used for the following step. The second is regression analysis. It was used to know the relation between the independent variables which comprises gross area and window-to-wall ratio(WWR) and the dependent variable, daylight area ratio(DAR). Moreover, peak cooling load saving ratio and daylight area ratio are in a logarithmic proportion. Important building features for daylighting schemes are highlighted.
