Welcome to the Commercial Building Disclosure Program

The Commercial Building Disclosure (CBD) Program is a regulatory program that requires energy efficiency information to be provided in most cases when commercial office space of 1000 square metres or more is offered for sale or lease. A quick video overview of the CBD Program can be found here. To find more information on the CBD Program, see 'What is CBD?' Information on how building owners can improve the energy efficiency of their building in preparation for a Building Energy Efficiency Certificate can be found here. If you would like to find out if you require a BEEC use our handy BEEC Guide.

COVID-19 Update

Due to the impact of COVID-19 on travel restrictions and social distancing, the Department has released updated Tenancy Lighting Assessment (TLA) Rules and an associated TLA Ruling to provide flexibility for building owners to meet their obligations under the CBD Program, while allowing building assessors to safely complete their work remotely where needed. Further information to assist those potentially affected by current COVID-19 preventive measures can be found here.
