The purpose of Energy Modeling is to adopt an integrated approach to building design so as to improve energy efficiency and achieve a superior performance in energy consumption. The superior performance in energy consumption is measured by comparing the annual power consumption of the Proposed Model (designed building) against the Reference Model (baseline building).
The Reference Model must meet the minimum requirements provided in the Building Regulations including the Envelope Thermal Transfer Value (ETTV) requirement and the relevant Singapore Standards. The Reference Model must also be the same as the Proposed Model in shape, size and orientation.
The Proposed Model must perform better than the Reference Model in terms of savings in total annual energy consumption through better design, higher efficiency of the selected equipment, lower thermal transmittance of building envelope, etc. The reference value shall be equal to the code compliance value.
For Green Mark GoldPLUS buildings, the simulation results from the Proposed Model must show at least 25% savings in annual energy consumption compared to the Reference Model. For Green Mark Platinum buildings, the simulation results from the Proposed Model must show at least 30% savings in annual energy consumption compared to the Reference Model.
