국부+전반조명(TAL)방식의 실내조도 예측을 위한 수치모델 개발

Abstract

Recently, Task and Ambient Lighting(TAL) gained its popularity as a lighting system in many office buildings in which the workstations are usually divided by interior partitions. The luminaires are equipped with various kinds of reflectors and louvers to reduce glare. The conventional prediction methods such as point-by-point method and split flux method. This study is to develop a simulation model to accurately predict interior illuminance of Task and Ambient Lighting through calculating movement of photon bundles emitted from artificial luminaires. The simulation methods commonly used are the Ray-tracing and Monte Carlo methods. Then, the accuracy of the numerical model was validated through measurements in a physical scale model room.
