Facts about BASIX Certificates and BASIX Energy Efficiency


BASIX Certificate

To comply with this scheme a BASIX certificate must be submitted at the Development Application stage to local government area councils of NSW along with other necessary documents. BASIX online assessment tool generates this certificate by collecting all the development specifications and calculating the energy efficiency, water efficiency and thermal comfort scores of the development if they are above the minimum required performance indices. All the provisions nominated on the BASIX certificate become part of the development plans and specifications which must be deployed during actual construction and be verified by the building's principal certifying authority prior to issuance of an Occupation Certificate.

BASIX Energy Efficiency

There are two major objectives which are being addressed by the BASIX energy efficiency index. First, more than 80 percent of all new and some refurbished residential building developments in NSW must meet the minimum BASIX energy efficiency targets and get a passing score from the online evaluation tool and second, all residential developments in NSW must produce 36 % less Green House Gas emissions compared to the state average. The energy efficiency target of the BASIX changes based on two factors which help to create fair and equitable results for each development in NSW. These factors are the climate zone of the development and the development type. Although NSW has 21 different climate zones for thermal comfort simulations, they are being bundled into three main groups and there are four development types as detached dwellings, low rise, medium rise and high rise multi-unit developments which create a 3 by 4 matrix covering all climate areas and developments types statewide. For each development type in each climate zone, a certain BASIX energy efficiency target is applicable which must be satisfied by the energy efficiency performance of the development design.
