BASIX Certificates


BASIXBASIX or Building Sustainability Index is an initiative introduced by the NSW Government in 2004. The scheme requires all new dwellings to be designed and built to achieve a 40% reduction in water consumption and greenhouse gas emissions compared to pre BASIX dwellings. The building design must meet the targets before a BASIX certificate can be issued.

All development applications for new dwellings must be submitted to Council with a BASIX Certificate. The certificate will outline how the dwelling will use less water and energy by addressing areas such as site location, size of dwelling, materials used and fittings for hot water, cooling and heating. A building certifier will ensure all BASIX commitments have been adhered to prior to issuing an occupation certificate.
