6 Star Energy Rating

When it comes to a 6 Star home, there is no comparison.

What’s best for your development?

With Stratawise, we know there are real benefits in building 6 Star energy efficient developments.

Don’t just ask for 6 Stars, demand it!

Stratawise is leading the industry in Western Australia by designing and building new homes that guarantee to meet the NatHERS 6 Star energy rating. That’s because at Stratawise, we believe in future-proofing your investment – giving you a home that’s efficiently designed and sustainably built.

6 Star homes for 6 Star savings – it’s why we’re putting our energy into energy rated homes.

Here’s another 6 good reasons why you should demand a NatHERS 6 Star home

Uses around 24%* less energy on heating and cooling compared to a 4 or 5 Star home

Higher level of energy effciency

Less impact on the environment by reducing your carbon footprint

Reduces artificial cooling/heating

6 Star energy rating as standard

Better resale value in the future

Caution

In regards to approval methods other than a NatHERS 6 Star rating, the Building Commission stated in 2013 that, “There are other ways of gaining compliance and approval for energy efficiency [such as via VURB] and although these aim to be equivalent to 6 star, this is not always the case. Therefore it is possible for your house to meet the BCA requirements but not be rated 6 star” – Building Commission, 2013. Further, the CSIRO in July 2017 issued a caution against using VURB where NatHERS software is used as the reference guide. In these circumstances, the CSIRO said that it “…may lead to poor comfort and energy performance in the finished dwelling.” – CSIRO, 2017.
