Homestar v5 consultation

**Update** Thanks to everyone who has taken part in this consultation, which was open until 17 July 2020. We've had some great feedback, and lots of it. You can read all about the feedback we received here.

Homestar is becoming more and more successful. The last year was probably the biggest ever year for the standard, as thousands of homes were registered.

But we know, working with you, we can make Homestar even better.

That's why we opened a consultation on Homestar. The feedback provided will help us to refine and improve Homestar, and will inform the changes we make for the new revised version, which will be released in about six months.

From conversations with many of our members, we feel some of the issues to tackle include:

  • The Homestar process needs to be simpler, but this needs to be balanced with improving outcomes.
  • We could better communicate the energy and comfort benefits of the different rating levels to homeowners, and the relationship between energy performance and different Homestar ratings is not as clear as it could be.
  • The holistic nature of Homestar is also not as clear as it could be. We need to show how Homestar benefits people, benefits the wider environment, and how the two are connected.
  • With a growing urgency to reduce climate change pollution, there is a clear need for a mechanism to drive a trajectory towards zero carbon homes.
  • Embodied emissions associated with constructing buildings is a growing hot topic and is not currently dealt with explicitly in the tool.
  • Homestar needs to find a way to always set benchmarks beyond the minimum requirements of the Building Code, and to be more ambitious than other regulations too. Since New Zealand signed the Paris Agreement and introduced the Zero Carbon Act, there is an increasing likelihood that Government will introduce regulations to ensure the built environment meets zero carbon ambitions. And, in the longer term, the Building Code could set out a trajectory to make homes progressively lower carbon.

Of course, Homestar will continue to also focus on construction waste, water efficiency, sustainable materials and other important sustainability items.

Homestar is owned, together, by all of us in the green building movement who want homes in Aotearoa to be healthy, warm, dry places for New Zealanders to thrive in. This consultation will be a key way to make sure we're doing our utmost to achieve this vision.
