Under the Building Energy Efficiency Disclosure Act 2010 (the Act), from 1 November 2010 there are mandatory obligations applicable to many commercial buildings. Most sellers or lessors of office space of 2,000 square metres or more will be required to obtain and disclose an up-to-date energy efficiency rating. Certain exceptions and exemptions apply (see Exemptions).
There is a transition period for the first year of the program where a valid National Australian Built Environment Rating System (NABERS) Energy base or whole building rating can be disclosed (see Transition Period).
From 1 November 2011 a full Building Energy Efficiency Certificate (BEEC) will need to be disclosed. BEECs are valid for 12 months, must be publicly accessible on the online Building Energy Efficiency Register, and include:
- a NABERS Energy star rating for the building - an assessment of tenancy lighting in the area of the building that is being sold or leased and - general energy efficiency guidance
The NABERS Energy star rating (exclusive of GreenPower) must also be included in any advertisement for the sale, lease or sublease of the office space.
The Act, implemented through the Commercial Building Disclosure (CBD) program, forms part of a package of measures to encourage building energy efficiency developed by the Australian, state and territory governments. CBD is a national program to improve the energy efficiency of Australia’s largest office buildings and is managed by the Australian Government Department of Climate Change and Energy Efficiency.
