What’s the benchmark for a truly sustainable house? That’s the question that Homestar® certifications set out to answer. Homestar is a national rating tool, run by an independent non-profit organisation called the Green Building Council. The rating—which works on a scale of 6 to 10—is broad and comprehensive, and aims to quantify houses based on health, warmth, and energy efficiency.
How does a house qualify for a Homestar rating?
The Homestar systems can apply to a house, apartment, or even multi-unit development. No matter which of these is being rated, the criteria are the same, and a property is ranked based on a few key categories. These are:
There is also an optional eight category: innovation.
The Homestar rating is also divided into two phases—Design and Build. The Design rating is based on the complete final plans before construction begins. The Build rating is carried out after the project is complete, and assesses how well the design has been implemented.
How you can get a Homestar rating approved
Here at Craft Homes, we firmly believe that higher quality, more energy-efficient Homestar homes are the way of the future. Not only are they a huge benefit to the environment, but they also improve the quality of life for Kiwi families across the country. We think there’s no reason that homes which are healthier, warmer, and smarter shouldn’t become the norm.
That said, achieving the level of quality needed to qualify for Homestar isn’t easy. Thankfully, there are several ways to achieve points through the Homestar system, many of which aren’t apparent straight away. Here are our suggestions on how to best get your Homestar rating approved.
Some other measures you can take to improve your application include installing mechanical ventilation to improve air quality, conserving water, and using better quality materials.
