Optimization of Artificial Lighting in Physiotheraphy Room of Hasan Sadikin Hospital

摘要

Lighting in buildings allows the occupants to do their task properly, but light with very high intensity may cause visual discomfort. Therefore, lighting in buildings, particularly the ones with high visual demand such as hospitals, should be designed to achieve specific room requirement and standard. This study aims to propose an optimized artificial lighting design for Hasan Sadikin Hospital (RSHS) in Bandung, in this case at the physiotherapy room. Computational model of the room was built in DIALux Evo, and was validated by comparing the measured and simulated daylight illuminance. Five different variables was observed and simulated for obtaining the optimum result. The weighted result was eliminated to get the highest rank for both local and general lighting. In this model, the optimum result is achieved using Philips Pacific II 2×TL5-28W TCW097 HFA luminaires, with wall reflectance of 0.86, luminaire rotation 90°, column spacing 3 m, and row spacing 2.1 m.
