Abstract: This paper presents an extension to an existing simulation tool that enables energy simulation of advanced daylight-controlled lighting systems with hourly dynamic thermal simulation. The climate-based daylight level in a reference point beneath each individual lamp is calculated and the light output from the lamps is scaled to meet user-defined illuminance levels in all reference points. The corresponding lighting power output is then given as input to the thermal simulation. The proposed lighting algorithm performs satisfying when compared to existing static lighting simulation tools. Furthermore, results from a test case demonstrate how the advanced daylight-controlled lighting systems may improve the annual energy performance of rooms.
