NABERS Energy Rating: Toward Happier and Healthier Spaces

NABERS is the National Australian Built Environment Rating System, a simple scheme to help building owners and tenants benchmark their greenhouse performance.  

For commercial property owners and lessors, NABERS can increase your asset’s value, help slash your operational costs, and leave a lasting positive imprint on the environment. 

A NABERS energy rating is required for office buildings over 1,000 square meters that are being sold or leased.

Go to the NABERS website to find a qualified NABERS assessor, who will assist you in all the rest of the steps.


Gather data about your energy consumption data, net lettable area, number of computers, hours of occupancy, and renewable energy info.


Your assessor will calculate your NABERS rating based on the information and documents you provide.


The NABERS Technical Team will audit your information and  then certify your final rating.


Your assessor will submit all your information to the NABERS technical team. You will pay the NABERS fee and the  assessor fee.

Key Benefits of NABERS for Commercial Buildings

Building owners and lessors can benefit from the NABERS rating by: 

Understanding your building’s performance and knowing how it compares to others (e.g., competitors)

 Having a competitive advantage of a lower environmental impact and lower running costs

Identifying areas where you can improve energy efficiency – which can lead to lower energy bills and reduced greenhouse gas emissions 

Enjoying increased asset value, as shown by studies, and enhanced business reputation 

For tenants, a NABERS energy rating can help identify areas for savings and improvements.

Understanding NABERS: Your Pathway to Sustainable and Efficient Building Performance in Australia 

NABERS is designed to assess buildings when complete and in full operation. Its main features are: 

It’s voluntary (except building subject to the CBD Scheme where it is compulsory)–a rating can be initiated by a building owner, manager, or tenant. 

It allows developers to “badge” the greenhouse performance of their new office development from the outset on the proviso that DECC will rate its actual operational performance and advise the tenants. 

It is now available for all Australian office buildings. Whilst originally a voluntary scheme, NABERS is now also part of the compulsory Commercial Building Disclosure Scheme. 

It rates a building according to its actual performance, using 12 months’ energy data. 

It is now available for all Australian office buildings. Whilst originally a voluntary scheme, NABERS is now also part of the compulsory Commercial Building Disclosure Scheme.

NABERS is the acronym for National Australian Built Environment Rating System. It is an energy efficiency rating scheme for commercial buildings, with a star rating and details about annual building energy consumption and greenhouse gas emission. 

You need a NABERS rating certification if your building is more than 1,000 square meters and being put for sale or lease. You may want to have a NABERS rating to guide you in improving your building’s energy efficiency, help increase your property’s value, possibly reduce your operating cost, and enhance your business reputation.

The NABERS rating certification is part of the Commercial Building Disclosure (CBD) Scheme, which requires it for office buildings over 1,000 square meters that are being sold or leased. Aside from compliance, you may apply for a rating certification to reduce energy and water consumption, save on utility bills, improve indoor air quality, increase property value, and attract and retain tenants. 

A NABERS Rating is calculated based on rating inputs that depend on the rating type and rating scope. For example, the inputs for a base building rating of an office building are address, postcode, rated area, rated hours, and annual energy consumption (electricity and gas/fuel use). For the complete table of inputs, refer to the Estimating NABERS ratings handbook. To get an idea of your NABERS rating, you could estimate it using the calculators at 

The star ratings represent the following: 

⭐= Making a start 

⭐⭐ = Below Average (opportunities for upgrades) 

⭐⭐⭐ = Average (market standards) 

⭐⭐⭐⭐ = Good (high performance) 

⭐⭐⭐⭐⭐ = Excellent (superior Performance) 

⭐⭐⭐⭐⭐⭐ = Market Leader 

A high NABERS rating means your building uses less energy and contributes to lower greenhouse gas emissions. As a result, you save on energy bills, the value of your building increases, current tenants are increasingly satisfied, and it will be easier to attract new tenants. 

Getting a NABERS rating starts with finding a qualified NABERS assessor. They will ask you to gather your energy consumption data and use those to calculate your rating. The assessor will then lodge your information and remit your payment to the NABERS Technical Team. Wait for your rating to be certified 

The exact timeline depends on your building’s size and complexity, but it typically spans 2 to 4 weeks from engagement to receiving your rating. 

Consult a registered assessor to determine what information will be needed. You may be required to prepare 12 months of bills for all energy consumption sources, layout plans, lease documents, computer count, occupancy hours, renewable energy information, and related information. 

The cost of getting a NABERS rating includes the lodgement fee and the assessor’s fee. For details, go to The size, type, and location of your building may affect the cost of a NABERS rating. To get one at a lower cost, check if the discounts and offers in the NABERS website applies to your building. 

In some jurisdictions, buildings are required to achieve a certain NABERS rating. For example, in New South Wales, all office buildings over 2,000 square meters must achieve a minimum NABERS rating of 3 stars. A NABERS rating can also be utilised as a pathway to achieving compliance with the National Construction Code (NCC). 

Aside from compliance, there are some incentives for buildings to receive a NABERS rating, including: government grants, government loans, tax breaks, increased property value, and improved tenant satisfaction. 

NABERS ratings are valid for twelve months from the issue date. It is recommended to renew your rating every year to track and showcase your sustainability efforts. 

NABERS offers invaluable insights into potential improvement areas, enabling you to implement changes and lift your rating in future evaluations.
