Lighting Energy Implication: A Simulation Study

Lighting requirement for different application is different. Understanding the working environment, selecting the suitable lighting fixtures, providing lighting solution and making lighting system more energy efficient and flexible using Lighting Management System (LMS) is the task for a lighting designer. Though lighting control is a proven concept, the complexity and high capital investment prevent the deployment of such schemes. This simulation assisted study investigates the energy and cost implications of 3rd-floor innovation building located in India, Manipal specifically at 13.35°N, 74.79°E. The energy savings and payback time of LED luminaire with Daylight and Artificial light integrated scheme presented, study shows the best results with zone control to dim the luminaire with respect to daylight on thewindow. This paper presents a methodology for detailed daylighting-artificial lighting simulation of auniversity building with an advanced lighting system and dimming levels for electric lights to provide the additional illuminance required so as to minimize electric energy consumption for lighting. The particular system considered is a double-glazed clear window and the building having one conference and 4 labs are highly glazed areas and these are the main concentration in our simulation study. This helps to understand the behavior of daylight-artificial light control system with smart sensor technology and effect of solar internal gains and annual discomfort hours with respect to different glazing area and control techniques.
