Office Tenancies

How it works

Measure, compare and share your office's environmental performance with NABERS.

NABERS helps you see how your office space measures up against others and identify opportunities to save energy and water, reduce waste, improve the indoor environment and more!

A NABERS office tenancy rating carefully considers the operations of your office space and excludes the rest the building. This ensures your rating is a fair and accurate reflection of your office’s performance.

After your office is assessed, you'll receive a rating from 1 to 6 stars, with 3 stars being average and 6 being market leading. Your rating is based how your tenancy's real performance compares to the industry benchmark.

NABERS is a government-backed sustainability initiative that has been independently assessing operational performance across the built environment since 1999. A NABERS rating provides an assessment of your office tenancy's operational performance using a consistent and recognised methodology, allowing you to benchmark your facility against peers and demonstrate performance with confidence.

A NABERS rating is simple way to share your office tenancy's environmental performance. It translates technical information into a simple star rating and can be easily understood across your organisation

A NABERS rating is the first step towards strong gains in office space performance. Use your rating to identify areas for operational improvements and cost savings.

Ratings and tools for office tenancies

For existing office tenancies

Energy rating

A NABERS Energy rating measures the energy efficiency of your office tenancy. Your rating considers factors including hours of occupancy, number of occupants and the size of the office space. It includes the Renewable Energy Indicator, which shows what percentage of your building's energy has come from renewable sources.
