REDIT REQUIREMENT
1 credit for demonstrating the fulfillment of at least 3 items out of the
following strategies;
2 credits for demonstrating the fulfillment of all of the following strategies:
For residential developments:
a)
To demonstrate compliance, energy simulation must be provided
to show that the average solar irradiance of all facades is lower
than 395 kWhr/m
2
/ apr-oct;
b)
Compliance is demonstrated by showing that a site permeability of
20% can be achieved between assessed building and nearby
buildings/obstructions;
c)
Demonstrate that 20% of the habitable space can utilise natural
ventilation either by the prescriptive approach or the performance
approach;
d)
Demonstrate that the OTTV of habitable spaces is less than or
equal to 30 W/m
2
; and
e)
Demonstrate that the VDF of habitable spaces are 50% more than
the baseline requirements.
For all building types excluding residential:
a)
Consideration of built form and building orientation to enhance
energy conservation;
b)
Consideration of optimum spatial planning to enhance energy
conservation;
c)
Consideration of building permeability provisions of building
features to enhance the use of natural ventilation;
d)
Provision of fixed or movable horizontal/vertical external shading
devices; and
e)
Provision of movable external shading devices for major atrium
facade windows or skylights.
A
SSESSMENT
The Client shall submit documentation to demonstrate compliance with
the strategy indicators:
Clear definition of the objectives of each energy efficient building
design, features, evaluated options, applications and verification of
the design strategies;
Annual energy saving estimation;
Other relevant supporting documentation for improved and
innovative ideas;
Relevant information to demonstrate sufficient effort has been
made on the required provisions and considerations, as well as the
final design solution that addressed the commitments; and
