‘Most sustainable’ house under construction
The most sustainable house in NZ has been built in Christchurch.
The “most sustainable” house in New Zealand has been built in Christchurch to a 9 Homestar rating, certified by the New Zealand Green Building Council.
The 140m2, two-storey home in Church Square, Addington, is due for completion in June.
An adjacent single-storey house in the development is also targeting a 9 Homestar Design rating.
The home features rain-water harvesting and grey water, water-efficient fittings, photovoltaic solar power and energy-efficient lighting and electrics.
All paints and sealants are low VOC (volatile organic compound), and other materials are certified by Environmental Choice NZ or Forest Stewardship Council.
A solar wall ventilation system uses the sun’s energy to pre-heat ventilation air, substantially reducing heating expenses. Slab-edge insulation to stop heat loss from concrete floor slabs, and hydronic underfloor heating also keeps the home warm.
Developer and architect Bob Burnett is an advocate for sustainable design.
