Mosman Council’s Development Control Plans (DCPs) require development to have energy efficiency in the design, construction, use and operation of buildings.

The Building Sustainability Index (BASIX) is a New South Wales Government tool that aims to encourage sustainable residential development. Additionally, the Residential DCP provides objectives and planning guidelines that aim to promote ecological sustainable development.

The Business Centres DCP provides detailed information on site layout and solar access, energy sources and systems, building construction and design, local air quality and alternative transport facilities.

Considering energy efficiency of the architecture when designing or renovating a home or office will not only ensure compliance with Council’s DCPs but can also lead to significant ongoing energy cost savings.

What is BASIX?

The Building Sustainability Index – or BASIX – is a web-based planning tool designed to assess the potential performance of residential developments against a range of sustainability indices.

People lodging certain residential development applications will be responsible for undertaking a BASIX assessment for each residential development proposal as part of the development approval process in NSW.

From 1 July 2007 BASIX will apply to alterations and additions work on existing dwellings where the estimated construction cost of the work is more than $50,000 and where development approval is required.

BASIX continues to apply to new dwellings, semi-detached dwellings, multiple dwelling developments and boarding houses or hotels that are under 300sqm and swimming pools with a greater than 40,000 litre capacity.

From 1 July 2007 there is a requirement that BASIX commitments be fulfilled. The Accredited Certifier must not issue an Occupation Certificate (whether interim or final) unless it is satisfied that each of the BASIX commitments has been fulfilled.

Applicants can generate the BASIX Certificate and find further information via the Department of Planning’ BASIX website www.basix.nsw.gov.au, or by phoning the BASIX Help Line on 1300 650 908.
