NABERSNZ™ Certified Rating

A NABERSNZ™ Certified Rating benchmarks your building or tenancy for its energy efficiency.

Benefits of a NABERSNZ Certified Rating

  • If you’re an owner, a high NABERSNZ rating can mean lower operating costs, more satisfied tenants and better occupancy rates

  • If you’re a tenant, a good NABERSNZ rating means lower energy costs and assurance that you’re in an energy efficient building

You can also use your NABERSNZ rating to assess progress of your energy improvements programme, and you can also use it in marketing material.

Start with a self assessment

You can do a free NABERSNZ self-assessment online that gives an idea how your building or tenancy may rate. You’ll need some basic data to complete the self assessment:

  1. Building address
  2. Net lettable office area
  3. All fuels energy use servicing the office areas over a 12 month period
  4. Weekly hours of occupation for the area under rating
  5. For whole building or tenancy ratings you’ll also need the number of workstations serviced by your office area.
