The house was built with energy efficiency in mind. Double glazing with thermally broken and argon filed windows throughout ensures that energy loss is approximately 1/4 of what a standard build would be. The house has been built to require as little heating, cooling, with a main courtyard allowing sun into the house in winter to warm the polished concrete floor, and with roof overhangs that prevent sun exposure during summer.
Whilst it is a big house on a small block, it has a similar energy footprint of a house less than half its size. It has been pre-plumbed for a grey water system, has solar cells on the roof, is insulated throughout, and achieved an 8.5 Star energy assessment (without the double glazing as that was not a feature in the assessment when built).
This house achieved a NatHERS rating of 8.5 stars using NatHERS accredited software (BersPro). Find out how the star ratings work on the Nationwide House Energy Rating Scheme (NatHERS) website.
