    1. Obtain a contract

    • Sign the Commitment Agreement contract and pay the fee
    • We'll send you a counter-signed contract
    • You then have a limited licence to promote your target rating using approved wording from NABERS

    You must then:

    2. Design, document and model

    • Design the building or space to operate at the energy performance level nominated in your Commitment Agreement
    • Prepare the model, simulation report and minimum documentation as detailed in the Handbook for estimating NABERS ratings

    3. Get an Independent Design Review (IDR) report

    4. Submit the IDR report

    • Email the IDR report to nabers@environment.nsw.gov.au
    • After we've approved the report you'll have a full licence to promote your target rating. This includes using the Commitment Agreement certificate and logo.

    5. Get a NABERS performance rating once the project is in operation

    • Arrange for a NABERS Accredited Assessor to carry out a Performance Rating on the premises when you reach the planned or agreed date for the building or space type’s NABERS Energy performance rating. This rating will be based on 12 months of real, operational energy usage.

    Why sign a Commitment Agreement?

    There are many reasons to sign a Commitment Agreement, including:

    • Increased capital value
    • Decreased operational energy costs
    • Marketing and communications opportunities
    • Attracting blue chip and/or anchor tenants, who often value or have requirements for high performing buildings
    • Increasing the likelihood of achieving your desired build quality and operational performance 
    • Respected process involving an expert third-party, Independent Design Review to highlight risks
