Recent research studies have proven that in a healing environment, good quality of lighting is essential to create a comfortable environment for patients to rest and recuperate, which can enhance their circadian rhythm, leading to improvement in the health of patients and this reduces their vulnerability to develop serious complications which could affect the healing process. Therefore, this study aims to examine Human Centric Lighting (HCL) performance of a retrofitted tropical hospital ward via a spectral raytracing simulation tool-ALFA. The simulation results will serve as a solid basis for developing the HCL recipe for the ward in temporal and spatial approach.
