A method for evaluating energy saving potential in lighting from daylight utilization

Daylight-linked lighting control systems can provide substantial savings in rooms with daylight availability. Energy saving potential from daylight utilization depends on several parameters of the room. Different methods to predict energy savings from daylighting exist. This paper aims to develop a new method that is easy to apply yet comprehensive, and gives a good indication as to the potential of energy saving from daylight utilization. The process is described step by step along with results from applying the method in a simulated test project as an example.
