The Commercial Building Disclosure (CBD) Program started in 2011 and requires office buildings where more than 2000m² is being sold or leased to declare a NABERS Base Building Rating, plus Tenancy Lighting Assessments (TLAs) for all affected tenancies.
The program was reviewed in 2014. The 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 $44 million in benefits between 2010 and 2014 by motivating activities to improve energy efficiency.
Following the review, the Government announced the move to lower the mandatory disclosure threshold on commercial office buildings from 2,000 square metres to 1,000 square metres
, effective from 1 July 2017. The extended program is projected to provide a reduction in end use energy consumption of 17,395 TJ, abatement of over 3.5 million tonnes of greenhouse gases and deliver around $60 million in benefits over the period from 2015 to 2019.
The lowering of the disclosure threshold is complemented by a decision to increase the validity period of the Tenancy Lighting Assessment from one to five years, effective for all new TLAs submitted from 1 September 2016. This means that building owners now can re-use their TLAs for up to 5 years, reducing the costs of compliance with the program. NABERS ratings still have to be renewed annually, however.
Energy Action has an unrivalled understanding of NABERS and TLAs, having had substantial input into the technical detail of both. If you need any services related to NABERS, TLAs, the CBD program or any other aspect of building energy efficiency improvement, contact us on 1300 553 551.
