Benefits of a NABERSNZ rating

A NABERSNZ star rating helps building owners and tenants to understand, compare and improve energy performance. Good energy management delivers cashflow benefits, and is rewarded with a higher rating.

A good Certified Rating is a strong indicator of market appeal. International experience has shown the benefits are more than just cost savings: with improved capital value, a more productive environment for staff, and lower vacancy rates as valuable co-benefits.

The starting point is to accurately measure and rate your building’s or tenancy’s energy performance.


NABERSNZ helps you understand how well you’re managing energy in your building or tenancy. You can get an idea of how your organisation is performing, and how you could improve, by using the free online self assessment tool. When you’re ready, a NABERSNZ Accredited Assessor can help you get a Certified Rating.


A NABERSNZ rating is much more than just an accurate measure of how well you are using energy. Your Accredited Assessor can help you identify areas where you can improve energy performance to make immediate and long-term savings, often without additional capital spending. Once you’ve started the journey to better energy management, you can improve your star rating over time. As there’s no obligation to publish Certified Ratings, your rating will help you decide what energy saving actions to target.


A NABERSNZ Certified Rating gives you a competitive advantage. It communicates at a glance your organisation’s commitment to energy management and can help you stand out in the marketplace. Ratings can be compared, regardless of building/tenancy size, or climate – it doesn’t matter if you're in Auckland or Invercargill.
