SR253 Sustainability of the New Zealand housing stock (2018)

This report contains the results of a BRANZ study into the operational environmental sustainability of homes in New Zealand, being the environmental impact of the way that we operate and live in our homes.

The major finding is that: New Zealanders live in homes that have high environmental impact, with homes built in the last decade having half the environmental impact of homes constructed before this.

While there are international aspirational targets for homes to have zero environmental impact, New Zealand homes are far from this ideal, rating between 2 and 4 stars out of 10 using the Homestar rating tool.
