Benefits of NABERSNZ
Building ratings are increasingly used as the tool for investors and tenants to benchmark building quality.
New Zealand is rapidly following the success of NABERS in Australia where ratings are required for all offices larger than 1,000 sqm. NABERSNZ ratings are now mandatory for many new government tenancies, and government is being asked to extend requirements in line with Australia.
Attract quality tenants
NABERSNZ ratings above 4 stars are now required by many government tenants. Rated buildings achieve higher occupancy, tenant satisfaction and better results for property owners, managers and tenants.

Frequently Asked Questions
A building with a cafe can be NABERSNZ rated. The assessor will confirm whether the cafe is used for only tenant purposes, our whether it is available to the public. So it can be determined whether the area and energy consumption should be included or excluded.
No, All three NABERSNZ rating types (base building, tenancy and whole building) rate the ongoing energy efficient performance of the building. In reality, basebuild rating results can be capped in some instances due to particular design limitations. However, this must be accounted for in any renewal or refresh works.
Yes, that is correct. New Government leases must be 4 star or greater already. These increase over time. More information can be found here https://www.procurement.govt.nz/property/lease-and-facilities-management/energy-efficient-buildings/
It is acknowledged that increased outside air volumes will increase energy use. However these aqre real energy consumption and carbon emissions. We hope it is a short term effect, but NZGBC will raise the issue with the wider NABERS network.
A Covid ruling document has been published which details how assessors can deal with this exact issue. Two of the methods provided are to assume a low occupancy of 20m2 per person, or use occupancy data from a previous rating. There is also COVID advice available on the NZGBC website for specific COVID related circumstances. Note that this will be updated in due course. https://www.nzgbc.org.nz/Attachment?Action=Download&Attachment_id=3261
This is clarifying an error in the presentation which indicated Greenstar As Built only last for a period of time.
NABERS in Australia provides ratings including water. NABERSNZ currently is energy efficiency only, and there are no plans currently to introduce water ratings. The Green Star Performance rating tool captures water use.
How should gas and water consumption be converted to KWH/sqm for Greenstar rating purposes?
Typically we will submeter the relevant HVAC/basebuild loads on each floor to account for these loads in the calculation. This metering is common in many buildings we monitor.
