A Christchurch family home has become the first house in New Zealand to receive a 9 Homestar rating from the NZ Green Building Council (NZGBC).
The new home, at 15 Dove Grove, Westmorland Heights – which produces virtually no power bills – has been awarded the rating after being assessed on its health, warmth and energy efficiency.
It’s been designed and built to prove that highly sustainable homes are achievable for Kiwi families.
Homestar is the NZGBC’s independent national rating tool it measures NZ houses and apartments on a scale of 6-10. A 6 Homestar rating or higher provides the assurance that a house will be warmer, drier, healthier and cost less to run than a typical new house built to building code, while a 10 Homestar rating is regarded as a world-leading house.
There are only four houses and one apartment block in NZ with a 10 Homestar rating and the Dove Grove property is the first in NZ to receive a 9 Homestar rating.
The Westmorland Heights home was built by Evolution, the energy-efficient homes division of Rilean Construction. Rilean Construction Canterbury director, Trevor Meikle, who built the house, says the home was designed to be lived in.
“It was designed to achieve maximum comfort and health within a reasonable budget, using Homestar criteria as a guide. We were not targeting a specific rating during the design and build process, so we are thrilled to realise we have succeeded so well,” Trevor says.
“This shows that incorporating energy-efficient and sustainable features into a family home is entering the mainstream market and no longer a niche activity. Evolution is dedicated to dispelling the myth that building a sustainable home is too expensive.”
The cost to build the property was approximately $2,700 per square metre, which includes a 30sqm deck made from composite materials that is almost fully-enclosed.
