Energy audit : an indicative survey on electricity services performance of old buildings in Malaysia
Kamaruzzaman, S.N. & Raha Sulaiman
Malaysian researchers reported that there will be a rapid growth on the electricity supplies with 4 percent growth per year and it is estimated that the maximum demand may achieved up to 23,099 MW in 2020. In its ninth Malaysian Plan, one of the important thrust is to improve sufficient and sustainable energy supply. On the other hand, energy consumed in Malaysia was 90% in the form of electricity. However, the new energy policy National Green Technology is believed only take place to new developments, new buildings and new systems. This awareness is so far has yet to take into consideration on the ideas and issues on old buildings. Most of the buildings in Malaysia are already old and therefore occasionally need a little "face-lifting" in the form of modernization in order to meet the needs demand. Nevertheless, most of these buildings were treated unfittingly especially in terms of energy efficiency. Most of the buildings energy consumption uses electricity for the running and operating such as running the plants, lighting, lifts and escalators and other equipment in the building. This paper investigates the energy use in four reused old buildings in Malaysia focusing on the electricity services. Electricity bills were gathered and analyzed. The analysis was performed on annual data, allowing comparison with published benchmark to give an indication of efficiency. It is anticipated that this study gives a good indication of the electricity consumption characteristics of reused old buildings in Malaysia.
