Setting targets using reverse calculators

Use our specialised reverse calculating spreadsheets to find out the maximum amounts of energy and water your building can use to achieve a certain star rating. 

This is useful if you are setting official or unofficial star rating performance targets for your building. 

Reverse calculations are available for:

  • Office buildings
  • Shopping centres
  • Hotels
  • Data centres

Results from the Calculators are for your information only, and cannot be reported or promoted. 

To promote or disclose an energy rating target, you must have a NABERS Commitment Agreement in place. 

What can I do once I have my reverse rating calculations?

Once you have the energy or water usage amount required for your target rating, speak to a sustainability expert or your Accredited Assessor to plan how to optimise your usage.
