건축물에 있어서 자연채광효과의 평가기법에 관한 비교연구 ( A Comparative Study on the Evaluation Techniques for Daylighting Effects in Buildings )

This paper is to compare three evaluation technigues for daylighting effects in builsings, i.e., the theoretical calculation based on daylight factor method using computer, field measurements, and phisical scale-model experiments. The results of the model experiments show very close values of daylight factor to those of the field measurements. When the computer program used in this study is consolidated by considering the affects of the solar altitude and the wall-solar azimuth, it can be used as a basis in estimating the electric energy consumed over a year in buildings.
