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 when required.

1-2 Dwelling Unit Indoor Comfort

Enhance dwelling unit indoor comfort either through the provision of better efficient airconditioners or good natural ventilation design.

(a)(i) Use of energy efficient air-conditioners that are certified.

  • Air-con Energy Saver, AES significantly reduces carbon emissions, improves air quality and can save you up to 30% on your energy costs for air-conditioning.
  • Households that are still using the old generation of air conditioner, proper energy saving air conditioning tips can be given.
  1. 1.    A dusty filter reduces air flow. Examine your unit’s air filters once a month and clean or replace filters when necessary. Keeping your filters clean can cut energy consumption 5 to 15%.
  2. 2.    Set the thermostat down to 720 F would increase your cooling costs 12 to 47%, depending on where you live.

(ii)Design for natural ventilation (applicable to development where air-conditioners are not provided).

  • Building layout design: Proper design of building layout that utilizes prevailing wind conditions to achieve adequate cross ventilation.

1-4 Lighting

Encourage the use of better efficient lighting or daylighting in common areas to minimise energy consumption from lighting usage while maintaining proper lighting level.
