Real Estate Commitment to Sustainability
One William Street is committed to achieving long term sustainable outcomes by addressing Environment, Social and Governance matters
It does this by using measured and verified performance information, such as utility bills, and converting them into an easy to understand star rating scale from one to six stars. For example, a 6 star rating demonstrates market-leading performance, while a 1 star rating means the building or tenancy has considerable scope for improvement.
For over ten years, NABERS has helped property owners, managers and tenants across Australia to improve their sustainability performance, reaping financial benefits and building their reputation.
NABERS is managed nationally by the NSW Office of Environment and Heritage, on behalf of Commonwealth, state and territory governments.
