The lighting system plays a significant role in our daily lives. Almost every building consists of different lighting systems based on the application. A good lighting design requires a control system that ensures the right amount of light is available where and when it is needed; this also minimizes the energy consumption of lighting installations. This simulation-assisted study investigated the energy and cost analysis of a three-storey building. Here we considered daylight controls using window blinds and artificial light integration with zone control to dim the luminaire with available daylight using sensors. The main focus while choosing classroom lighting for education would be on achieving the required lighting levels and reasonable comfort levels. The optimal usage of daylight ensures energy savings and uniformity, it is observed that the Light Power Density value of LED with control techniques is much lower than without control. Using control techniques, the energy consumption is lower, and the payback period is higher. Using control techniques in an existing system or a system replaced with LED results in higher energy savings, provides more incredible comforts, and reduces the use of artificial lighting.
