Have you heard of Green Star and NABERS, but have wondered what they actually mean? Well, Green Star is not a sick celebrity, and NABERS is not a soapie on TV that you may (or may not) admit to watching!
Green Star and NABERS are both green rating tools currently operating in Australia that rate the sustainability features of a building or development. Both ratings are voluntary, but more and more developers and property owners are opting into these schemes.
The main difference between the two tools is that Green Star rates the design of the building (both at the conceptual and at the ‘as built’ stages) and NABERS rates the effectiveness of the operation of the building (after it is built and is operational).
Green Star ratings are issued by the Green Building Council of Australia. NABERS ratings are issued by the NABERS scheme, which is run by the NSW government, but can be used in any State.
To obtain a Green Star rating, your development will be rated against a number of tools, depending on the type of building. For example, there is a specific office design rating tool that is used to measure the sustainability features of an office building design. Within that tool, you can obtain a number of credits for certain sustainability design features. For example, you can obtain credits for using recycled wood or having more bike parking than required by the local government. The more credits achieved by a particular design, the better the Green Star rating - up to a maximum of a five Star Green Star rating. However, the Green Building Council of Australia will not certify projects that achieve less than four stars, and there are certain eligibility criteria that must be achieved. It sounds simple, but the actual process can be very complex and complicated.
To obtain a NABERS rating, your building will be assessed for energy and water efficiency. The lower the consumption of these resources, the better the rating. You can obtain a ‘performance rating’ for an existing building or a ‘commitment rating’ for a new building.
Once a NABERS or Green Star rating is achieved, the relevant bodies will allow you to use their trademark to promote your rating.
There is no legal requirement at this point in time for a developer or property owner to apply for and obtain either rating. However, it’s likely that in the future the government will adopt similar principles used by Green Star and NABERS when developing building, property and planning legislation. In the meantime, these ratings are being used as marketing tools, with some government agencies choosing not to enter into leases of buildings unless that building has a minimum Green Star and/or NABERS rating. Listed companies may also require that any buildings they occupy or own comply with similar rating tools to firm up their green credentials.
Property owners need to be careful how they promote their building’s rating, as each body restricts marketing a building as a Green Star or NABERS rated building unless certain approvals have been obtained. You should seek legal advice if you have applied or are applying for a Green Star or NABERS rating before distributing any marketing materials, to make sure you comply with the copyright laws of each tool.
If you would like our assistance with a Green Star or NABERS matter (for example, reviewing commitment agreements or trademark licences) or if you need more information about how the tools work, please call or email one of our team members.
We will be running a ‘Back to Basics’ seminar in July 2010, which will go into more detail as to how each tool works. Please contact us if you would like more information on this seminar or would like to attend.
