Introduced by the NSW Government, BASIX, the Building Sustainability Index, ensures homes are designed to use less water and be responsible for fewer greenhouse gas emissions by setting energy and water reduction targets for houses and units.
If you are making alterations or additions to your home, you must include a BASIX Certificate with your Development Application. The NSW government has introduced BASIX (Building Sustainability Index), a web-based planning tool designed to assess the potential performance of residential development to meet sustainable water and energy requirements.
You can obtain a BASIX Certificate online, by following the guide at the BASIX website.
You will need to enter data relating to the house or unit design such as location, size and building materials into the BASIX tool. BASIX analyses this data and determines how it scores against the Energy and Water targets. The design must pass specific targets (which vary according to location and building type) before you can print a BASIX Certificate.
It is compulsory to submit a BASIX Certificate when lodging a development application to construct a new dwelling, dual occupancy (whether attached or detached), new villas, town houses and residential flat buildings.
A BASIX assessment is also required for development involving alterations and additions to dwellings (where the cost of works is greater than $50 000) or involves the installation of a swimming pool or a pool and spa.
If you do not include your Certificate when you lodge your application, Council cannot accept or start to assess your proposal.
