Energy and Water Efficiency

New legislation sets new standards for energy and water efficiency

State Governments in the following states in Australia have taken proactive steps to ensure new homes are designed and built with the latest energy and water efficient designs and products. These programs are supported by legislation which sets a new standard for developing more sustainable homes.

New South Wales

In Sydney and New South Wales, the BASIX (Building And Sustainability Index) building regulations call for a 40% reduction in mains water usage. A typical single dwelling design will meet the BASIX target for water conservation if it includes:
1. showerheads, tap fittings and toilets with at least a 3A rating;
2. a rainwater tank or alternative water supply for outdoor water use and toilet flushing and/or laundry
