자연채광 시스템의 성능 평가를 위한 실내 조도 예측 및 조명제어 컴퓨터 모델 개발

Abstract

It is necessary to provide sufficient daylighting for the high quality lighting in interior space. In these days various kinds of daylighting systems are developed and applied to buildings, however the difference of the purpose of an object room and a physical environment makes the Daylighting system to be unuseful. Therefore it is necessary to estimate the performances of the Daylighting system using the Computer program to apply the Daylighting system usefully. The purpose of this study is to develop the computer program using the Monte Calro Method and Ray-tracing technique to estimate the performances of the Daylighting system in interior space and the consumption of electric energy by dimming control of electric lighting. The accuracy of the computer model was validated through measurements with physical scale models under real clear sky conditions.
