This 10-Star Energy Rated all electric Positive Energy Building (PEB) is generating up to 4 times more energy than it uses. This house, designed with the goal of becoming Australia’s most energy-positive residence, may indeed have achieved that status.
Featuring double-glazed windows, 66 solar panels on the house and 24 semi-transparent solar panels integrated into the carport, (29.90kw total) In-roof solar systems eliminate the need for any traditional roofing materials by using the standard size PV panels itself as roof finish. This innovative in-roof system, the largest of its kind in Australia, is complemented by a 9kw solar thermal system with an 800-liter hot water storage tank, a 15kw battery, and a 12kw air-to-water heat pump. This powerful combination enables solar-powered hydroponic floor heating or cooling all year around, eliminating the need for gas or air-conditioning. A 40,000-liter rainwater tank supports water sustainability. The 190m² green roof is one of Australia’s largest residential green roofs installations. It can hold up to 4000 litres of rainwater in its storage layers. The inverted green roof, with a special insulation board on top of waterproofed concrete structure keeps the house cool and warm. The carport is currently awaiting the installation of an electric vehicle charger. The house is very air tide. All doors are fully framed no gaps under external doors. A decentralized ventilation system with heat recovery is installed.
The garden is all native and includes several large rocky riverbeds with a large rain garden that collects and filters excessive rainwater runoff during heavy rain events.
In 2024 the house produced 26.5 MWh electricity and exported 17.2MWh to the Grid.
In 2023 the house produced 28.6 MWh and exported 18.01 MWh to the Grid.
The hot/cold water system can produce up 160kwh/day hot or cold water and can store 60kwh solar energy.
