What is NABERS?

At NABERS, we know that sustainable buildings are not only better for the planet, but they also make happier and healthier spaces that we can all thrive in.

NABERS (National Australian Built Environment Rating System) provides simple, reliable, and comparable sustainability measurement you can trust across building sectors like hotels, shopping centres, apartments, offices, data centres, and more.

Since 1999, we have proven that “What gets measured gets managed.” Our customers have reduced their energy use by an average of 30-40% over a 10 year period.

Our rating system has driven financial growth and solid returns in portfolios across building sectors. It has directed corporate procurement by clearly demonstrating their operational performance and sustainability achievements.

A NABERS rating helps you to accurately measure, understand, and communicate the environmental performance of your building while identifying areas for cost savings and future improvements.

    What is NABERS

    NABERS is a simple, reliable sustainability rating for the built environment. Like the efficiency star ratings on your fridge or washing machine, NABERS provides a rating from one to six stars for buildings efficiency across:

    • Energy
    • Water
    • Waste
    • Indoor environment

    This helps building owners to understand their building’s performance versus comparable buildings in the same sector, providing a benchmark for progress.

    NABERS Star Rating criteria

    NABERS ratings are valid for twelve months. This annual model helps ensure that your rating represents a building or workplace’s current operational performance.

    NABERS has partnered with Climate Active to provide a Carbon Neutral certification.

    A NABERS rating helps building owners to accurately measure and communicate the environmental performance and progress of buildings. It also identifies areas for savings and improvements.

    Why do we need to rate buildings?

    The built environment has a significant global environmental impact and is a contributor to climate change.

    Buildings are responsible for 40% of the world’s carbon emissions and use approximately:

    • 40% of the world’s energy
    • 30% of the world’s available drinking water.

    Environmentally friendly buildings are better for the bottom line, better for staff and clients, and better for the planet.

    Benefits of a NABERS rating

    • Compare: NABERS ratings form the basis of a robust sustainability strategy. They provide a fair benchmark for a building’s energy and water efficiency, enabling comparison across the industry.
    • Validate and communicate: NABERS provides cost-effective, high-trust, and independent validation of sustainability data, ensuring confidence in reporting it publicly and communicating it simply.
    • Track and improve: NABERS star ratings are an essential framework for annual reporting and sustainability strategies. With annual ratings, performance improvements and reduced energy and emissions can be demonstrated over time.
    • Competitive edge: Enables building owners to communicate simply and with confidence that their building has a lower environmental impact and running costs to prospective buyers, renters, procurement teams or hotel guests.
