A house energy rating is a measure of the relative energy efficiency of
a dwelling. Ranging from 0 to 5 stars, the rating is based on an estimate
of the amount of energy which would be required to heat the dwelling in winter and cool it in summer.

FirstRate, the SEAV’s (Sustainable Energy Authority of Victoria) house energy rating software, achieves an energy rating by assessing the interaction between the building’s design, the materials used, and the orientation of the dwelling.


Improving the energy efficiency of buildings is one of the measures
taken by the Australian government to address global warming issues.

Within 5 years, energy efficient homes will save Victoria more than
200,000 tonnes of greenhouse gases annually, by minimizing the use
of non-renewable energy (coal, oil and natural gases). This is equivalent
to removing 45,000 cars from the roads or planting 750,000 trees.

In Victoria new townhouses and units currently require a mandatory
4 star rating, with some developers having a 5 star covenant for some
new estates.

The Victorian Premier Steve Bracks announced on July 4th that a transition standard would operate from July 1st 2004. During the 12-month transition period, builders would have three options for new buildings:

OPTION 1: 5 star energy rating for the building fabric (achieved through design, insulation and double glazing and other measures);

OPTION 2: 4 star energy rating for building fabric plus water saving measures (AAA shower head, taps and a pressure reduction valve) and a rain water tank;

OPTION 3: 4 star energy rating for building fabric plus water saving measures (AAA shower head, taps and a pressure reduction valve) and a solar hot water system.

From July 2005 all new homes will be 5 star energy efficient and include major water saving devices, such as AAA rated taps and fittings, water tanks or solar hot water systems.

The owner of a 5 star rated home will enjoy the immediate benefits of lower energy bills and a more comfortable living environment which is up to 10 degrees cooler in summer and up to 5 degrees warmer in winter.


Comfort Smart’s accredited Energy Raters are trained in the use of FirstRate.

To provide you with an energy rating for your house design, we require the following:

• A completed Comfort Smart detail sheet (visit www.comfortsmart.com.au)

• A set of plans showing the floor plan, elevations and site orientation
