Energy consumption of buildings takes up about a third of Singapore’s total electricity production. This paper investigates the energy consumption of an office building in Singapore using numerical simulations. By obtaining the building parameters and necessary dimensions, the simulation results were evaluated and validated by comparing with the actual building energy consumption results. However, some variations are being observed between simulated and actual building energy consumption. Simulations were conducted to investigate the air conditioning energy savings due to the installation of cool coating onto the office building roof surface. Results from the simulation showed that cool coatings with high reflectance and emittance reduce the monthly air conditioning energy consumption by 8.3 – 10.2%. This paper also investigates the energy savings due to the increasing of set-point temperatures from 23 ℃ onwards which amounts to 8000+ SGD per year and at the same time, providing maximum thermal comfort level for the occupants in N3.2 office building.
