NABERS assessments

benefits of NABERS



Improve the rental yield, capital value and tenant stickiness of your building. A high NABERS rating is considered a symbol of sustainability leadership and good management. Buildings with high ratings demonstrate the following benefits:

What is NABERS?

NABERS (National Australian Built Environment Rating System) is a national rating system that measures the environmental performance of Australian buildings.

A NABERS assessment can be conducted for:

  • Office buildings
  • Data centres
  • Hotels
  • Shopping centres.

It measures energy efficiency and optionally water usage, waste management and indoor environment quality.

How does the star rating work?

The performance of your building or tenancy is compared to the performance of other similar buildings in the same location.

A zero to six star rating is assigned.

NABERS rating scale

  • 6 stars - Market leading performance
  • 5 stars - Excellent performance
  • 4 stars - Good performance
  • 3 stars - Average performance
  • 2 stars - Below average performance
  • 1 star - Poor performance
  • 0 stars - Very poor performance

Office buildings and mandatory disclosure

Commercial Building Disclosure

The Commercial Building Disclosure (CBD) program is a national program created by the Department of the Environment and Energy that sets mandatory disclosure rules for office spaces.

At the point of lease or sale, office building owners/lessors of spaces must:

  • obtain a Building Energy Efficiency Certificate (BEEC)
  • disclose their NABERS star rating in advertisements.


Currently - applies to spaces >2000m2

1st July 2017 - applies to spaces >1000m2

Business Energy Efficiency Certificate

A Building Energy Efficiency Certificate (BEEC) consists of:

  1. NABERS assessment 
    • Conducted every year
  2. Tenancy Lighting Assessment
    • Lighting assessment for the area of the building being sold, leased or sub-leased
    • Conducted every five years

Who is affected?


Building owners* 

who are selling or leasing office space

NABERS Real estate agent

*Applies to corporations (ie not individuals or partnerships)

There may also be other exclusions – see and exemptions

How we can help with nabers


If your office space is subject to Commercial Building Disclosure obligations (for spaces > 1000m2) our accredited assessors will:

  • conduct a NABERS assessment
  • conduct a Tenancy Lighting Assessment
  • look after all paperwork to lodge your BEEC.


2. NABERS only

We can also conduct NABERS assessments for office spaces not covered by mandatory disclosure legislation (ie smaller than 1000m2).

NABERS assessments can also be conducted for:

  • shopping centres
  • data centres
  • hotels.

3. Energy efficiency opportunty report

An assessment alone won’t reduce your energy costs but is an important first step to benchmark your energy usage. The most important leg of this journey is what you choose to do AFTER your assessment.

On completion of your assessment, we will prepare an Energy Efficiency Opportunty Report for you. This is a high level overview of options to improve your NABERS rating and save energy costs. It may include considerations such as:

  • lighting
  • HVAC
  • solar
  • power monitoring
  • peak load analysis.

If you choose to investigate any of these opportunities further, we can prepare a free, no obligation quote.
