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. An Independent Review of the CBD Program is occurring during 2019 - further details here.
