Abstract

Air-conditioning & mechanical ventilation system (ACMV) and lighting is the main contributors to total of the building energy consumption. In Malaysia, commercial building consumes around 32.7% of total energy. This project aims to develop an ACMV and lighting retrofit model using the FKM’s campus technology. IES <VE> was used to simulate and predict the retrofit outcome of the academic building. The propose and prediction of ACMV and lighting retrofit is compare with the standard requirement from MS 1525:2014 and Green Building Index (GBI). The retrofitting plan is by adjusting the set point temperature to 24°C can reduce the energy consumption for the ACMV system. Based on the simulation result, by introducing proper retrofitting, the amount of energy saving for one month is around 30.183 MWh or 15.7%. The number of artificial lighting were reduced to minimize the energy usage. Moreover, several retrofitting plan were also introduced in order to promote energy efficient of the building. Lastly, the retrofit plan can be achieved even without compromising the indoor comfort for the occupants.
