Abstract

The significance of energy efficiency has grown with the increasing electricity consumption worldwide in recent years. The share of energy consumption in architectural structures is relatively high due to this increasing energy consumption. In this study, a smart building lighting control model is developed to improve the energy efficiency of lighting and to find the optimum status regarding lighting comfort and energy saving. The controllable lighting and 11 electrochromic glass with variable light transmittance were controlled with the developed control algorithm to meet the lighting comfort requirements, and energy savings of up to 20% were obtained. The results show that to have a successful lighting system, the artificial lighting source should be controlled depending on the lighting level in the room. In addition, using controllable lamps and electrochromic glass in regions and climates with higher solar radiation intensity is crucial for sustainable energy and environmental goals.
