Energy Audit

What is it about?

The purpose of this paper is to present the efficiency of electricity use and potential of electricity reduction at residential colleges in University of Malaya, Kuala Lumpur. The work presented applies an energy audit when energy consumption data were collected and analysed for a five‐year period. The total savings of electricity used at residential colleges were identified through the difference between average total energy use in a year (kWh) and minimum electricity usage.

Why is it important?

The study finds that residential colleges with special features of building layout performed better with regard to electricity consumption due to the utilisation of day lighting and natural ventilation. The floor area of the rooms, volume, density, enclosure and facade design also influenced the total electricity usage of the buildings.The study can be used as baseline data for a tropical region particularly on current electricity usage and potential of energy conservation in buildings.
