Green rated existing buildings

The Green Star SA – Existing Building Performance Tool covers the same environmental categories addressed in the Green Star SA new building tools (Design / As Built). It also focuses on the efficient operations and management of the building that affects optimal performance.
 
The rating is valid for a period of 3 years in order to ensure the building is continually well operated and maintained. Items such as energy and water monitoring, management policies and plans are required in order to achieve the rating.
