When will 6 Star Energy Rating be
6 star for new homes, additions and alterations will be
effective in Victoria as of 1 May 2011. If your design began prior to May 1
2011, the building surveyor can lodge a dispensation to allow compliance with
the old 5 Star Standard.
What building work is subject to 6
All new homes, apartments, renovations and additions (class
1, 2, 4 & 10a). Some simple work
that does not require a building permit will not need a .
What is required?
A report prepared by an Accredited Assessor is required
showing the design achieves a 6 star . New homes also require the installation of a
solar hot water system or rainwater tank for toilet flushing.
What does the higher rating mean?
For home owners it means a house that is more naturally
comfortable for longer periods of the year. It may also mean lower utility
bills, a reduction in greenhouse emissions, and better resale values.
What design changes will be required?
A 6 star energy rating can be achieved a variety of ways. Most likely increased insulation to roof,
walls and suspended floors will be required. Improved glazing may not be necessary
if other elements are good – e.g. Orientation, insulation, and appropriate
shading – however, many homes will require double glazing.
Will it cost more to build?
Given the building has good design and orientation for its
specific location, increased costs to reach 6 stars should be minimal. In any case, it makes good financial sense to
seek the right advice from a reputable Accredited Assessor to ensure costs are
kept to a minimum.
If renovating or extending, will you
need to bring the entire home up to 6 Star?
If you're doing an alteration or extension, and its volume
is 50 per cent or more of the existing home, the whole house needs to be
brought up to 6 stars.
