New voluntary rating system to drive building energy efficiency NABERSNZ

building energy efficiency image

A new voluntary rating system, NABERSNZ, measures the energy performance of New Zealand's office buildings and aims to transform the way office buildings use energy, helping to reduce energy use and costs.

NABERSNZ, developed in partnership with the New Zealand Green Building Council with assistance from the business community, is modelled on a similar system in Australia.

The system rates commercial building energy use on a scale of one to six, with certified ratings being issued on the level of energy performance. It is expected that in time, the system will become the industry-recognised benchmark for energy performance in office buildings, similar to the energy star mark used for electronic products and appliances.
