In January 2021 we introduced a requirement for all mandated agencies to complete National Australian Built Environment Rating System New Zealand (NABERSNZ) assessments on leased and owned buildings. NABERSNZ is the energy rating system used to measure and compare the environmental energy and carbon performance of Government office buildings.
The standards are compulsory for all mandated agencies who occupy single-tenant, co-tenanted, or co-located government office accommodation. NABERSNZ ratings are currently undertaken in owned and leased buildings when the aggregated occupancy is ≥ 2,000m2 (base building rating), and ≥ 5,000m2 (tenancy rating).
NABERSNZ assessments and ratings
We have reviewed the NABERSNZ standards to ensure they remain fit-for-purpose.
Following our review, several changes will take effect from 1 November 2024:
In leased buildings, a NABERSNZ rating is only required if:
- an agency is intending to lease a site for 4 years or longer, and
- agencies are occupying more than 50% of the building’s net lettable area (NLA). This includes a single agency or multiple agencies in one building.
To clarify: If you enter into a lease, with Rights of Renewal that extend beyond 4 years, and government occupy more than 50% of the NLA, then a NABERSNZ assessment is required.
Agencies can opt-in to obtain a Tenancy rating where the lease is less than 4 years or where
government occupancy is < 50%. Where agencies opt-in, the results will be included in the CNGP dashboard.
If an agency, or multiple agencies, occupy ≥ 50% of a building they need to do the following assessments:
• If NLA ≥ 2,000 m², a base build rating is required
• If NLA ≥ 5,000 m², a tenancy rating is required
These changes reduce the number of agencies and buildings in scope. We have identified that 22 agencies are in scope with 63 buildings requiring an assessment. Of these buildings:
• 48 (76.2%) of buildings have been rated
• 12 (19.1%) have an assessment planned or underway
