Energy Efficiency Analysis and Financial Assessment at Faculty of Engineering, UNISEL

Rajendran Sinnadurai

Abstract


Energy is an important factor in the development and growth of the economy.    Therefore, the availability of adequate supplies of energy is a strategic issue for any country             including Malaysia. Nowadays people are more concern about energy efficiency and conservation   and one of the focal point is the energy consumption in buildings. This research focuses on energy             efficiency analysis at Faculty of Engineering (FOE), UNISEL. Through successful           implementation, the energy costs would be minimized, wastes and the environmental hazards          would be reduced. A detailed load and energy audits were completed for FOE. Two major parts,   which are efficient illumination design and occupancy control were examined. For efficient          illumination design, the existing lighting design was reviewed and the potential energy saving by             de-lamping the lights were determined and validated with actual photometric measurements. The        energy saving through occupancy control was also determined. Both controls reduce energy usage.             There is a general awareness of the opportunities for reducing the cost of electricity          consumption in FOE but the progress in implementation is slow and stagnant. In FOE, there are     several different uses of electrical energy such as lighting, air conditioning and other devices. The energy that contributes to the total electrical usage within the faculty was computed. Finally,    the payback period is calculated.
