The purpose of this study was to provide the visual evaluation data in a workstation space when different lighting types were applied. For the performance evaluation, Radiance program was used for simulations, and the mock-up room(15.0×11.6×3m) was used for the actual test. The results of this study were as follows; 1) When the indirect lighting simulation data using Radiance was compared with the actual data in a small workstation space, there was a 6.5% difference. Therefore, Radiance program was proved to be useful for the evaluation of lighting performance. 2) The results show that the straddled layout has higher light levels (higher light ratio (%)) and the centered layout condition has lower light levels (lower light ratio (%)) in most cases. 3) Also, the results show that the indirect luminaires and the straddled layouts provide higher uniformity, whereas the direct luminaires and centered layouts have lower uniformity.
