The NABERS program has been around for 20 years, benchmarking the energy efficiency of commercial properties by measuring their consumption and expenditure and now the rating tool is coming to residential buildings and your Owners Corporation.

If you’ve ever pondered why some building consume and spend less (and therefore have lower Owners Corporation fees) than others, then energy efficiency could be the answer.

The tool will become available to Owners Corporations, building managers and strata managers later this year, with the NABERS program set to celebrate its 20th anniversary in June.


NABERS is a government-backed national rating system that measures the environmental performance of Australian buildings.

In fact, NABERS stands for National Australian Built Environment Rating System.

It measures the energy efficiency, water usage, waste management and indoor environment quality of a building.

For residential buildings, the rating will only apply to the building’s common areas and will not include private lots.

Every building’s energy efficiency is given a rating out of six stars.

A six-star rating means your building is market leading, a three-star rating means it is average, while a one-star rating means your building is not energy efficient.

Where the NABERS tool is different to others is that it measures the performance of a building based on operational data.

The tool is well established in the commercial space and will soon be available to residential buildings.

The program hopes to provide awareness about energy consumption by providing property owners the ability to compare one building to another in a fair and balanced way.

Owners will then be able to see how their building is performing in terms of energy efficiency and identify areas where investment – and savings – can be made.


NABERS provides you and your fellow lot owners the perfect opportunity to see just how well your building is running – at least from an energy efficiency stand point.

The residential tool will only measure the common areas of the property and its common energy consumption, meaning individual apartments are not factored into the rating.

At the moment, there’s no real indication for apartment owners or even potential owners what the energy consumption of a building is like.

The energy performance of the building directly relates to the levies that owners pay or can expect to pay if they’re looking at purchasing a property within the building.

A rating – either good or bad – can help to highlight potential areas for savings or investment for owners.

Lower ratings normally mean that there are a lot of quick wins to be had and some huge savings to be made.

It could be something as simple as changing the light bulbs. The rating can be used to define where your building is wasting energy and where you can improve your building’s efficiency and reduce costs.

A good rating is usually a sign that the building is well managed and operated.

Every NABERS rating is nationally recognised and valid for a year.


To get a NABERS rating, you will need to get in touch with and engage a NABERS-accredited assessor.

Your assessor will conduct a site visit and will need 12 months of utility bills.

The assessors will be looking at the level of servicing the building has and what is being used by the common property in the building.

Central air conditioning, lifts and car parks are among the biggest items on their inspection list, as they look to get a better understanding of the servicing of the building and how its common areas consume energy.

Once the assessor has completed their visit, they will combine that data with 12 months of utility bills before submitting their rating to NABERS, who quality check and certify the rating.

Every rating is valid for 12 months.

The NABERS program for residential buildings will start with a pilot program due to commence in early June.

NABERS is currently looking for new assessors and will be running Accredited Assessor training courses coming up in May/June for both new and existing assessors to become trained in NABERS for Apartment Buildings.
