Homestar for home owners
Homestar is an independent rating tool that certifies the health, efficiency and sustainability of New Zealand homes.
It’s been around since 2010 and is a quality-assurance mark – a bit like Energy Star for appliances, or the WELS scheme for water efficiency, and is run by the Green Building Council, a not-for-profit organisation working to make New Zealand homes healthy, warm and dry.
The current Building Code sets minimum standards for internal moisture, ventilation, energy efficiency and insulation, but even a new home built to Code can perform poorly. In fact, the temperature in many New Zealand homes is at least 2˚C lower than the World Health Organisation’s minimum indoor daytime temperature of 18˚C, according to a 2006 He Kainga Oranga study.
Homestar means warmer, drier homes
A high-rating Homestar home has a heavily insulated thermal envelope for optimal energy efficiency, so your home will be warm in winter and cool in summer (and cheaper to heat). Excellent ventilation and moisture control are standard, meaning less mould and a healthier environment when winter illnesses strike.
You don’t need to install flash new gadgets to get a good Homestar rating: nearly half the points a house can earn relate to energy, health and comfort. That’s because getting the basics right – good orientation for sun, high levels of insulation and controlling moisture – is vital to create a healthy, efficient home.
