Potential Energy Saving by ACMV Temperature Setting in University Building

Abstract

Lecturer office building is particular of important buildings in Universiti Tun Hussein Onn Malaysia. Lecturers will spend their time mostly in office if no learning and teaching process in classroom. This study aims to discover potential energy saving by air conditioner temperature control setting of lecturers building at Block C15, C16 and C17 respectively. Several steps have been done to achieve the objective. A study on type of ACMV, building identification, location, the usage trend, air-conditioner quantity, and the published electrical tariff by TNB were done to familiarize with the building of study. Result was found that about 62% of electrical energy was used on Air Conditioning and Mechanical Ventilation System (ACMV). This is the most energy consumption used in lecturers building. From calculation, the monthly electrical energy consumption of lecturer buildings was near to 56.963MWh. With the proposed potential saving measures, which is air condition temperature setting, lecturers building is estimated to reduce the usage of electrical energy for about 10 to 30% per month. More potential saving could be found in future study if there is designated system that studies the energy consumption trend of the building.
