Energy Auditing Measures for a Private Educational Institution in Sta. Ana Pampanga: A Case Study

Abstract

One of the ways to identify the areas of the building that wastes energy then reduces energy consumption is by conducting an energy audit. This study aimed to conduct an energy audit, specifically a Walk-Through Analysis, on Holy Cross College, a Type 1 Designated Establishment. Specifically, it evaluated the energy consumption practices of the institution when it comes to their lighting system, equipment usage, employee energy conservation practices, air-conditioning units, and building envelope. Aside from the result of the qualitative observations of the researchers, they also conducted a quantitative energy conservation assessment brought by the illumination and cooling systems of HCC. It was found out that there are energy saving opportunities that could be utilized by the institution to reduce their energy consumption and save utility costs. The results of the analysis showed that the ACUs of every building is the system where energy is being wasted or used inefficiently. The EEMS proposed by the researchers were all presented with references and their corresponding investment cost and level of savings. Aside from that, if every room in each building were to set their ACUs to 24 degrees Celsius, they would be able to save an approximate of 15063.84 kWh which is worth ₱ 115,153.18 monthly. Lastly, if HCC is to invest and utilize twenty-six pieces of 15W LED Bulb for replacement in the college corridor, the total investment cost would be ₱ 3,250.00 which has a return on investment of 214.2%, and a payback period of about 3 months and 25 days.
