Harmony 9 has been unveiled as Australia's first net carbon neutral energy rated home.

It is a sustainable housing prototype that follows the success of Mirvac's 6+ Star energy efficient homes at Waverley Park and its Australia-first 6 Star shopping centre at Orion Springfield Town Centre.

Key features throughout the home include:

• A 'reverse brick veneer' construction with bricks on the inside and the timber frame on the outside. The heavy-weight materials inside the home create internal mass and stabilise the core temperature
• A Smart Energy Meter that allows real time monitoring of energy and water use
• Very high wall and superior insulation in the ceiling and internal walls
• Double-glazed windows with timber frames, sealed with a natural oil
• North-facing living zones and windows, with correct shading and maximum cross ventilation
• Recycled furniture and joinery including a dining table created with recycled timber from original Waverley Park stadium, chairs constructed of cardboard and upholster fabrics  composed from natural fibres and hemp
• 3.6 kW solar panel system that provides clean power and a hot water system with two solar panels
• Recycled construction materials including recycled timber and bricks
