New and retrofitted existing buildings – 3 yearly system efficiency audit

• Three-yearly energy audit on cooling system

• Annual submission of building info & energy consumption data

• Min. GM standard for existing buildings

• Phase 1– Any hotel, retail building or

office building– GFA > 15,000m2

– Installing/replacing chilled-water cooling system.

– Must meet minimum GM Standard for Existing Buildings

• Lifespan of chilled-water cooling system is between 15 – 20 years

Energy Consumptions in Buildings

Cooling system

Lighting

Equipment

Others

Cooling system accounts for as much

as 50% of the building’s total energy

consumption.

Min. GM Standard for Existing Buildings1

Planning

• Owner engages a PE(Mech).

• PE (Mech) looks into the overall building design and ensures that the building can achieve at least Green Mark 50 points.

• Owner to submit the Green Mark design score, retrofitted design, drawings, computations for approval before commencement of the energy improvement works.

Retrofitting

Completion

• Owner must complete the energy improvement works within three years from the date of approval of the design score by BCA.

• Submit the Green Mark as-built score (at least 50 points) (including commissioning of the cooling system).
