Energy modelling is an integrated approach that provides a good gauge of the energy consumption of the building, identifies energy efficiency opportunities and gives an indication of how a building is going to operate. Higher-tier Green Mark Certifications (i.e. GoldPLUSor Platinum) are required to demonstrate energy savings through Energy Modelling.
Methodology
Energy performance of a building is measured by comparing the annual power consumption of the Proposed Model (designed building) against the Reference Model (baseline building).
General requirements
- The Reference Model must meet minimum requirements stipulated in the Building Regulations including the Envelope Thermal Transfer Value (ETTV) and relevant Singapore standards
- The Reference Model must be the same as the Proposed Model in shape, size and orientation
- The Proposed Model must perform better than the Reference Model in total annual savings in energy consumption through:
- Better building design
- Higher Improved equipment efficiency
- Lower thermal transmittance of building envelope
- Any other relevant methods
- Simulation results from the Proposed Model must show at least 25% savings in annual energy consumption compared to the Reference Model for Green Mark GoldPLUSbuildings, or 30% energy savings for Green Mark Platinum buildings.
