(c) Natural Ventilation
Prescriptive Approach
1 credit if 20% of habitable areas meet the ventilation
requirements.
2 credits if 40% of habitable areas meet the ventilation
requirements.
3 credits if 60% of habitable areas meet the ventilation
requirements.
4 credits if 80% of habitable areas meet the ventilation
requirements.
5 credits if 100% of habitable areas meet the ventilation
requirements.
Performance Approach
1 credit if 20% of habitable areas satisfy the Area-Weighted
Average Wind Velocity (AAWV) requirement.
2 credits if 40% of habitable areas satisfy the AAWV
requirement.
3 credits if 60% of habitable areas satisfy the AAWV
requirement.
4 credits if 80% of habitable areas satisfy the AAWV
requirement.
5 credits if 100% of habitable areas satisfy the AAWV
requirement.
(d) Daylight
1 credit if 80% of the habitable areas have glazing with a vertical
daylight factor (VDF) 50% higher than the minimum requirement
in APP 130.
(e) Active Building Systems
Two pre-requisites must be achieved to gain the credits:
Compliance with the latest Building Energy Codes (BEC) by
Prescriptive Option; and
In the case where air-conditioning units are provided by the
developer, units selected shall either be Grade 1 or 2 under the
Government’s energy efficiency labelling scheme for room coolers.
Three different categories fall under the section Active Building Systems,
HVAC systems in common areas:
1 credit for a 20% energy reduction compared to current BEC.
2 credits for a 25% energy reduction compared to current BEC.
Artificial lighting system in common areas:
1 credit for a 20% energy reduction compared to current BEC.
2 credits for a 25% energy reduction compared to current BEC.
3 credits for a 30% energy reduction compared to current BEC.
Vertical transportation in common areas:
1 credit for a 10% reduction from the maximum allowable
electrical power rating.
