This Ruling aims to clarify how assessors and building owners should account for On-site Renewable Electricity Generation Systems in a NABERS rating for any building type.
The Ruling v1.1 replaced the previous Interim Ruling v1.0 published in August 2020 and is to be read in conjunction with the respective NABERS Rules as they apply to the building type.
NABERS continues to encourage open dialogue and welcomes feedback on the Ruling so that necessary improvements can be made to ensure it is fit for purpose across all building types. A key goal is ensuring sites with On-site Renewable Electricity Generation Systems are able to realise their full benefit appropriately in their NABERS ratings.
