Abstract
This paper is concerned with the estimation of energy use in office buildings in Malaysia and with the energy use of major equipment. Energy intensity (Ell - a measure of a building's energy performance is estimated for Malaysia and compared with a number of selected countries. Air conditioners are shown to be the major energy users (57) in office buildings, followed by lighting (19), lifts and pumps (18) and other equipment (6). It is estimated that 77,569 MWh of energy can be saved and a huge reduction of emissions achieved through the application of advance glazing, compact fluorescent lamps (CFL), insulation, housekeeping, and by raising thermostat set point temperature of air conditioners, and reducing El. It is also estimated that a very substantial amount of energy can be saved by making use of energy-efficient motors in building systems with different motor loading percentages. Finally, it can be shown that the use of variable speed drives (VSDs) and energy-efficient motors leads to substantial energy savings and an enormous reduction in emissions.
