NABERSNZ

The NABERSNZ rating scheme was implemented in 2015 and can be used to assess how well a building uses its energy. It uses a similar ‘star’ rating system to the Green Star system, ranging from 0-6 stars. It acts as a post-occupancy tool and aims to provide a ‘real world’ rating system.

Cosgroves have accredited staff who are able to provide feedback on the use of the NABERSNZ Rating process in order to achieve a certified rating for their clients.
