Abstract
Since year 2005, Universiti Sains Malaysia has paid over RM 8 million annually on electricity
utility bill. The figure is increasing and expected to be over RM 10 million by year 2010 based on
the current increment rate. Energy consumption at lecture halls complex (KDK) buildings has
been a concern since they have a longer operation period than administration buildings. The
operation period was up to 17 hours per day for KDK compared to 9 hours per day for the
administration buildings. Therefore an energy audit has been conducted to analyse and identify
the level of energy consumption in KDK. Three lecture halls complex buildings were chosen for
the field study, namely G03, G27 and E48. These buildings were different in ages but they were
of similar mechanical and electrical (M&E) systems. The results show that the Building Energy
Index (BEl) was influenced by the age of buildings. Older building has a higher BEl compared to
the new building. The BEl for KDK G03 and E48 were 142. 18 and 132.79 kWhlm21year
respectively. BEl for KDK G03 with a 30-year old water-cooled air-conditioning and mechanical
ventilation (ACMV) system was found as competitive as KDK E48 with a 2-year old air-cooled
system. KDK G27 with a 20-year old air-cooled system consumed 56% more energy than new
system and had the highest BEI of 207. 77 kWh/m/year.
