Frequently Asked Questions
Why do office buildings need a BEEC/NABERS rating?
Australian Government legislation requires a NABERS Energy Rating and BEEC Certificate for the sale or leasing of any office spaces over the threshold of 1,000m2.
Additionally, many commercial office buildings chose to voluntary undertake NABERS Energy and Water Ratings on an annual basis to reflect their sustainability goals and to improve the operational processes at their sites.
What are the benchmarks used for NABERS office ratings?
I have a newly built tenancy/building and need a BEEC, can this be done?
Additionally, a new building, or site that has undergone a major refurbishment, and that has only recently been issued with its “Certificate of Occupancy”, is exempt from needing a BEEC for 2 years from the date of the COO or until it is 75% Occupied with office tenants (whichever occurs the first).
We are doing some upgrades and changing all lights in the building to LEDs, will this improve my NABERS rating?
We have recently done upgrades on the chillers and plant equipment for a Base Building, will this improve my NABERS Base building rating this year?
We are planning to install solar on the rooftop, can you tell us how this will affect our NABERS ratings?
What is the new Renewable Energy Indicator tool NABERS has introduced?
How can we keep track of our NABERS Ratings being currently undertaken when using NettZero service?

How does the NABERS rating benefit the building owners?
The NABERS Rating compares like-for-like buildings and so is an excellent tool to understand your building versus other similar buildings.
Experts in sustainable buildings

As an advocate for sustainable development, I am passionate about buildings that not only benefit the present generation but also leave a positive legacy for future generations.
Buildings can be major contributors to greenhouse gas emissions, energy consumption, and resource depletion. By implementing green building practices and rating standards, we can significantly reduce these negative impacts, mitigate climate change, and conserve precious natural resources.
By prioritising environmental friendliness in commercial properties, we can secure the value of both the built assets and our environment.
