Building a New Home in NSW? Here’s a Quick Guide to BASIX Requirements


We understand there’s a lot involved in building a new home! Just one of the many tasks is fulfilling BASIX requirements, and we’ve got a handy guide to help you understand it.

What is BASIX?

Introduced by the NSW Government, BASIX, (the Building Sustainability Index), is a relatively new planning tool which affects all residential developments throughout NSW with a total estimated cost of works of $50, 000 or more. BASIX assesses water and energy efficiency of developments, and by meeting practical design requirements, new residential dwellings and alterations use less water and energy, saving you money and protecting our environment.

How does BASIX work?

BASIX is an online program accessible by everyone. The user enters design data relating to the proposed development – such as location, size, and building materials – into the BASIX tool. BASIX analyses the data and determines how it scores against the energy and water targets. In Sydney, for example, a development must meet a minimum score of 40 for both the water and energy components. The design must pass specific targets before meeting BASIX requirements, and is then eligible for the BASIX Certificate.

The BASIX Certificate

This lists all the commitments and sustainability features the user has agreed to, and the Certifying Authority will check these at various stages of construction. The BASIX Certificate must be attached to the development application before it can be processed.

Sustainability Options

BASIX is flexible and easy to use, allowing users to determine how they will meet targets from a wide range of options such as rainwater tanks, water-saving fixtures, efficient hot water systems, improved insulation, natural heating and cooling, energy efficient appliances, passive solar orientation, natural lighting and native plants for gardens.
