Sustainable housing

Our sustainability

We are committed to creating healthy and sustainable communities for Defence members, their families and the broader community.

Since 1 July 2010, all of our new housing has been built to a minimum six star energy rating (NatHERS). Where possible, our new housing complies with the Australian Government's Livable Housing Design Guidelines - Silver Level.

We focus on five key areas

  • low energy consumption
  • low water consumption
  • effective waste management
  • human wellbeing
  • biodiversity of local flora and fauna

Design

All of our homes are built to achieve a minimum six star energy rating.

Where possible, our new homes incorporate solar panels to reduce fossil-fuel use. In our major developments we've started using solar-powered community street lighting, and recycled grey water on landscaped areas.

All our homes are designed for the climate in which they are located. Our award-winning tropical demonstration house in Lyons, Northern Territory features:
  • solar orientation and design to ventilate and cool the home
  • covered outdoor areas to maximise living space
  • landscaping to shade areas of the home exposed to strong easterly and westerly sunlight.

Construction

Our new homes are designed to make use of natural airflows and solar orientation to decrease the need for artificial heating and cooling.

We apply practices in our construction process such as:

  • using materials that are suited to the local climate and weather, and have less impact on the environment
  • working with local providers to source building materials, and landscaping supplies. This reduces the environmental impact of long-haul transport and helps build links with the local community
  • ensuring outdoor areas within our developments are landscaped to complement native and local flora.

We recently completed two new homes in Townsville, Queensland which achieved seven star Building Energy ratings. The homes have optimum orientation and cross-ventilation, large eaves to provide protection from the sun, and use light-coloured external walls and Colorbond roofing. Both homes were also fitted with energy and water saving devices.

We are researching the construction of 'off the grid' houses.
