Authors: Ramilo, Runddy; Datta, Sambit ; Embi, Mohamed Rashid
Buildings are accounted for approximately 40% of global energy consumption and one‐third of global greenhouse gas (GHG) emissions. A significant proportion of energy utilization is due to the spread
of heating, ventilating, and air conditioning (HVAC) installations in response to the growing demands for better thermal comfort of the built environment. While the proportion of energy consumption of
buildings is an issue, architects have not seriously considered to innovate new solutions to tackle the problem particularly existing office building which is centrally airconditioned and consumed substantial amount of energy. Only few has been research to improve its performance to save energy that can be used as bench mark for post occupancy evaluation for existing buildings. To elucidate this issue, this paper is a result of a case study using building performance simulation tool to optimized energy for an actual office retrofit project in the tropics. Its objectives are to explore an energy optimization strategy using building performance simulation tool (IESVE) and to improve existing office building envelop for utmost energy efficiency. The result revealed that using parametric methodology through building performance simulation tool, an office building has the potential to achieve 26.8 % energy savings.
