CBD Program Changes

We offer tailored Engineering Solutions to improve the efficiency of any type of site, anywhere in Australia.


Since the 1st of July 2017, the area threshold for the CBD (Commercial Building Disclosure) program was lowered from 2000m² to 1000m².

Under the changes, a Building Energy Efficiency Certificate is required for any office space of 1000m² or more before it is offered for sale or lease. A BEEC is made up of two components, a NABERS rating and a tenant lighting assessment.
