NABERS FY23 Annual Report delivers impact at speed and scale

News | 18 Oct 2023

Showcasing the unprecedented delivery of new NABERS rating tools and enhancements.

NABERS has proven that measurement leads to better management, and our FY2023 annual report confirms this.

Key highlights from the FY23 Annual Report include: 

  • 21% growth in Sustainable Portfolios Index ratings 
  • 27% increase in data centres rated  
  • 26% increase in offices with NABERS Indoor Environment ratings    
  • 200% growth in offices with NABERS Waste ratings of 5 or more stars  
  • 18% increase in shopping centres with repeat ratings 
  • 85% of survey respondents agreed with NABERS approach to measuring embodied carbon.

Some key industry achievements over the past two decades include:

  • 1.7 billion dollars in energy bills saved by our customers  
  • 11.57 million tonnes of CO2 emissions saved

The NABERS Renewable Energy Indicator was launched in June 2023. The Indicator discloses the percentage of fossil fuels and clean renewable energy that a building consumes, and is displayed on every NABERS Energy certificate. This gives building owners, investors and tenants extra information, as they make the transition to net zero. NABERS Director Carlos Flores highlighted the role of collaboration in bringing the Indicator to market. “We are very thankful to the hundreds of organisations, individuals and industry bodies in the building sector who advocated for, and helped shape the Renewable Energy Indicator over the past two years,” Carlos said. “Their efforts were instrumental in designing a new Indicator that is helping NABERS evolve to drive buildings to be energy efficient as well as fully decarbonised”. 

In September 2022, NABERS launched a rating tool to help owners and operators of warehouses and cold stores. Speaking at the launch, the Australian Government’s Assistant Minister for Climate Change and Energy, Jenny McAllister, hailed the new rating tool as another step towards “the broad effort of industry, business and communities across the country in securing the future of our energy system, our economy and our climate”. 

NABERS also transitioned Office ratings to the NABERS Perform platform to create a better user experience for our customers and Assessors.  

NABERS has been working in partnership with the GBCA and collaborating with industry groups to develop a standard that can measure, verify and compare embodied carbon in new buildings and major refurbishments. The FY23 Annual Report outlines the overwhelming support for NABERS’ approach to measuring embodied carbon: 85% of respondents either agreed or strongly agreed with our approach. We'll continue working together with government and industry to keep driving de-carbonisation and building a more sustainable future.

The annual report puts a spotlight on shopping centres. When the first cohort of shopping centres received NABERS ratings in 2010 the average rating was 0.9-star; last year, a record 238 shopping centres obtained a NABERS rating, and the average 4.5-star Energy rating proves the NABERS mantra, “measurement leads to better management”.

NABERS delivers a “foundation of data” that is easy to understand. But one of NABERS’ “structural advantages” is its army of NABERS Assessors. “It’s not just about measuring and managing. It’s about having skilled people to help you” says Steve Ford, Head of Sustainability and Energy at GPT Group.
