Commercial Building Disclosure

Building owners and tenants are realising that energy efficiency has many business benefits. It offers a cost-effective way to manage rising energy prices, increase productivity and reduce operating costs. It can also increase the value of your property and attract higher rental returns.

Commercial Building Disclosure (CBD) Program

Commercial Building Disclosure (CBD) is a national program which requires sellers and lessors of large commercial office spaces to provide energy efficiency information to prospective buyers and tenants. This is creating a more informed commercial property market, and encouraging more energy efficient buildings and reduced emissions. NABERS is used in the Commercial Building Disclosure Program.

The CBD Program is an initiative of the Council of Australian Governments (COAG) and is delivered by the Australian Government Department of the Environment and Energy.

Review and changes

The CBD Program originally mandated the disclosure of energy efficiency information for commercial office spaces of 2000 square metres or more. From 1 July 2017 the scope of the Program was expanded to cover commercial office space of 1000 square metres or more. The changes followed a comprehensive review of the CBD Program in 2015 and public consultation on the proposed changes to the Program.


The CBD review found the Program had delivered a reduction in end-use energy consumption of 10,020 TJ, abatement of 2 million tonnes of greenhouse gases and has delivered $15 million in benefits ($44 million if you include GHG reductions) between 2010 and 2014, by improving the energy efficiency of Australia’s large office buildings.

Next steps

The Department of the Environment and Energy is now working to develop reference materials for building owners on how to increase their NABERS rating.
