10-star rating home unveiled
10 Homestar Built rating has opened its doors in Christchurch.
The first home to achieve a 10 Homestar Built rating has opened its doors in Christchurch.
Architectural designer Bob Burnett has developed the 140m2, two-storey home at 11 Church Square, Addington.
It is the first 10 Homestar Built rating awarded in New Zealand. Launched in 2010, Homestar is a system that rates the health, comfort and efficiency of New Zealand homes, on a scale of 1-10.
It takes into account energy, water, waste, ventilation, health and comfort and other environmental factors, at both design and build stage.
There are currently 200 Homestar-rated projects throughout the country. Plans will be available for a small royalty fee, and the Addington show- home will be open to the public for at least 12 months.
NZ Green Building Council chief executive Alex Cutler says the home has good orientation for sun and high levels of insulation.
The home features a combined grey water and rainwater system, water-efficient fittings, photovoltaic solar power and energy-efficient lighting and electrics. Paints and sealants are low VOC (chemicals), 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 hy- dronic underfloor heating also retain warmth.
External wall frames are least 140mm thick and provide resistance to wind and earthquake loads that exceed building code requirements.
