PRIVATE
OPEN SPACE THE PERFORMANCE APPROACH
The
objective may be achieved by application of the performance criteria
listed below:
(1)
Private open space is clearly defined for private use
(2)
Private open space areas are of dimensions to suit the projected
requirements of the dwelling occupants, and to accommodate some
outdoor recreational needs as well as providing space for service
functions.
(3)
Part of the private open space is capable of serving as an extension
of the function of the dwelling for relaxation, dining,
entertainment, recreation and children's' play, and of being accessed
from a main living area off the main dwelling.
(4)
Provision and location of private open space take account of user
requirements for privacy, outlook, and nearby public open space as
well as the natural features of the site.
(5)
Orientation of private open space helps to achieve comfortable
year round use.
PRIVATE
OPEN SPACE THE PROVISIONS APPROACH
(1)
AT GROUND PRIVATE OPEN SPACE: Private open space for the dwelling
should have a total minimum area of 35m2, where:
-
The minimum dimension is 3m
-
One part of the private open space is the principal area.
This area should be not less than 16m with a minimum dimension of 4 m.
It should be steeper than 1 in 20 (5%) and should be directly
accessible from a living room of the dwelling.
-
Screening should be provided where appropriate, to ensure
privacy to the users of the open space.
(2)
AT ABOVE GROUND LEVEL: The principal private open space of the
dwelling should be provided in the form of a balcony having a minimum
area of 8 m2, and a minimum dimension of 2 m with direct
access from a main living room of the dwelling.
ENERGY
EFFICIENCY THE PERFORMANCE APPROACH
The
objective may be achieved by application of the performance criteria
listed below:
(1)
Buildings are sited:
-
In temperate climates, to maximise solar access to the
north facing wall, having regard to slope, views, existing
vegetation and overshadowing.
-
In hot humid climates, to maximise use of cooling breezes.
(2)
Building envelopes and internal layouts are designed to minimise use
of fossil fuel for heating and cooling. (3) Building windows are
located, sized and shaded to facilitate thermal performance
(4)
Buildings have an area of roof with appropriate orientation and pitch
that is suitable for the installation of solar collectors.
(5)
Building materials and insulation are selected to assist thermal
performance
(6)
Air movement within dwellings is designed to reduce use of fossil
fuel and to improve comfort levels.
(7)
Landscape design assists in microclimate management for the reduction
of fossil fuel use and the conservation of water.
