We’ve developed a new report on a range of key CBD metrics, now available on our CBD Program reporting webpage.  

You can see the new selection of graphs/visuals below the existing PowerBI data analytics report.  The new report provides trends and data on:

  • National and state based commercial building energy use since 2011, in MJ per rated square metre.
  • Star rating progress for commercial buildings since 2011 (by area weighting and certificate count).  
  • State based average star ratings since 2011
  • Nominal Lighting Power Density changes in Tenancy Lighting Assessments (TLA’s).
  • TLA certificate counts per year

Some key report highlights include:

  • Average consumption per square metre has decreased by 41% from 2011 to 2025.
  • Based on Net Lettable Area (NLA), average NABERS Energy star ratings have increased for each state since 2011.
  • In 2025, over 52% of Building Energy Efficiency Certificates were issued for buildings rated as 5 star and above. As a comparison, in 2015 only 30% of BEECs were for 5 star or above buildings!
