A Study on the Comparison of Calculated the Indoor Illuminance Values by Lighting Simulation Softwares for Suitable Prediction About Indraft of Daylight

자연채광 유입에 따른 실내 조도의 적합한 예측을 위한 조명시뮬레이션 소프트웨어 비교 연구

Architecture design has need of daylight prediction to utilize daylight efficiently. But it is difficult to predict the exact value of available daylight in buildings. Using various lighting simulation software is not difficulty, but we can find different results under the same conditions. The purpose of this paper is to compare simulation values from various software such as Lumen-micro 2000, Lightscape 3.2, and Relux 2006. The same space and parameters of daylight(location of space and window, date, time, and skylight condition) are considered to conduct various simulation conditions.
