How the rating works

A NABERSNZ Certified Rating gives a star rating, from 1 to 6, that clearly shows your building’s energy and water performance compared to others.

It is valid for 1 year, so each year you can get a new assessment to track your progress. This encourages continuous monitoring and means that when your energy and water efficiency improves, you’ll be able to prove it.
