Improper lighting conditions in educational institutions may impact both the health and working capacity of students. significant amount of energy consumption is generally attributed to lighting systems since most institutions are still utilizing non-efficient illuminants, including incandescent, tungsten halogen, and high intensity discharge light bulbs. This study aims to conduct a preliminary energy audit of the twin theatre building using physical survey by counting the numbers lamps, their wattage and the hours of usage. The lighting system integrating day lighting with weather conditions requires a simulation tool and to compare the power consumption with the base case and proposed case. Propose energy-saving strategies evaluate the impact on energy efficiency of lightings systems. Renewable Energy and Energy Efficiency Technology Screen (RET Screen) is a software used in this study to analyze greenhouse gasses. Energy consumption from the two scenarios was compared, and emission savings was evaluated. The preliminary energy audit utilized RET Screen to calculate base case energy consumption, considering lightings systems quantity, operating hours. The software RET Screen was used to develop the energy model and Greenhouse gas emissions reduction. The study case to be a Twin theater of a Kaduna state university main campus. and the electrical energy expenses decreasing by 10.512 kWh per year of the Twin theatre, which is over 75%. The greenhouse gases (GHG) emissions dropped by 149.8 kgCO2 eq. annually of the Twin theater which is about 47.3% This analysis supports the advantages of using LEDs instead of fluorescent lamps, also reduces GHG emissions despite the high lumen deterioration of LEDs.
