Part 1: Energy Efficiency
1-1 Building Envelope

Enhance the overall thermal performance of building envelope to minimise heat gain thus reducing the overall cooling load requirement.

1-2 Air-Conditioning System

Encourage the use of better efficient airconditioned equipment to minimise energy consumption.

The systems to be considered are as follows –

(a)(i) Air-Conditioned Plant:

• Chiller

• Chilled-water pump

• Condenser water pump

• Cooling tower

(a)(ii) Air Distribution System:

• Air Handling Units (AHUs)

• Fan Coil Units (FCUs)

(b) Unitary Air-Conditioners/Condensing Units :

• Single-Spilt Unit

• Multi-Spilt Unit

• Variable Refrigerant Volume (VRV) System

(c) Sensors or similar automatic control devices are used to regulate outdoor air flow rate to maintain the concentration of carbon dioxide below 1000ppm

1-3 Building Envelope – Design/Thermal Parameters

Enhance the overall thermal performance of building envelope to minimise heat gain which would improve indoor thermal comfort and encourage natural ventilation.

(a)  Minimum direct west facing façade through building design orientation.

(b)  (i) Minimum west facing window openings.

(ii) Effective sunshading provision for windows on the west façade with minimum shading of 30%.

  • Window solar film
