Victoria’s first 10-star energy rating home uses solar to slash bills

NAtHERS 7-star rating

Victoria’s first 10-star energy rating home achieves zero electricity bills using solar power and a range of energy saving measures.

The coastal home at Cape Paterson faces harsh Victorian winters and warm summers. Yet it functions without mechanical heating and cooling systems.

The four-bedroom display home features a passive solar design. This heats and cools using cross-flow ventilation, thermal mass concrete floors and heavy-duty insulation.

Mild temperatures all year round

According to construction company The Sociable Weaver, internal temperature stays between 18 and 26 degrees all year round.

Recent data shows the 4.8 kW solar installation generates twice as much electricity as residents consume. Yet the carbon-positive residence retails for only $499,000.

Non-toxic building materials and products also came with minimal packaging. Builders could therefore meet zero waste criteria.

10-star energy rating home sets the bar high

The Gippsland home shows how renewable and energy-saving technology can boost efficiency.

Because most new homes now come with a minimum six-star rating, more Australian residents can save money using solar panels and home battery storage.

Creative builders  and architects are also increasing their energy ratings. This is according to the Nationwide House Energy Rating System (NATHERS).

  • A 8.4-star cottage renovation in Adelaide’s Beulah Park features a 5.2 kW solar installation.
  • An 8-star heritage cottage in Melbourne’s Yarraville has a 4 kW solar PV system. It also features sustainable materials and a green roof.
  • A ‘hemp house’ in the NSW town of Mullumbimby runs on solar power. It also has hemp wall insulation.

House solar panels offer many benefits then. They can power heating, cooling and hot water systems. Excess energy produced during the day can also be stored for peak evening and overnight use.

Smart houses more energy efficient and cost-effective

Australian property developers are always looking for new ways to make homes more energy efficient.

Because this reduces power bills and saves residents money, it’s a great way to give their houses marketing appeal.

Meanwhile, Mirvac has just selected a family to live rent-free in a prototype energy-efficient home in Melbourne’s middle suburbs. The home features solar panels and battery storage.

The ‘house with no bills’ project is part of Mirvac’s sustainability strategy called ‘This Changes Everything’. The Zimmerman family will live in the Cheltenham test home for 12 months to see if they can achieve bill-free living.
