Commercial Building Disclosure (CBD)

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.

The commercial building sector is responsible for around 10 per cent of Australia's total greenhouse gas emissions and this figure is rising. Improving building energy efficiency is one of the quickest and most cost-effective ways to reduce greenhouse gas emissions and help mitigate climate change.

The CBD Program requires most sellers and lessors of office space of 1000 square metres or more to obtain a Building Energy Efficiency Certificate (BEEC) before the building goes on the market for sale, lease or sublease.

BEECs are valid for up to 12 months and include:

• the building's National Australian Built Environment Rating System (NABERS) Energy for offices star rating

• a tenancy lighting assessment of the relevant area of the building

The aim is to improve the energy efficiency of Australia's large office buildings and to ensure prospective buyers and tenants are informed of the building’s energy efficiency performance when making decisions.
