The rotating, energy-efficient solar home Girasole

In Crace, Canberra, Anna and Phillip Burroughs reside in a multi-award-winning solar home named ‘Girasole’. It’s the widest rotating home in the world – using solar power to rotate on its axis to gather maximum amounts of solar panel and allow for a novel and exciting living area for the Burroughs’.

Girasole was designed by DNA Architects and Industrious Design in 2012-2013 – with the house being offered a six star energy rating. Construction was completed by MAG Constructions in 2013 and in the middle of the year the Burroughs happily moved in to their amazing new home which boasts a 120,000 litre underground water tank, 10.5kW solar panels, north-facing living room windows, the highest insulation rating possible (using polystyrene external cladding) and LED lighting throughout. 

A touchscreen panel in the house is pressed to commence the rotation of the 56 tonne home – which also has an automatic option to ‘follow the sun’. It takes about 10 minutes for the house to do a full 360′ rotation and, amazingly, takes about the same energy as a lightglobe to turn around due to extremely clever and energy efficient construction and design. 

According to the Internet, ‘Girasole’ is Italian for sunflower – an apt choice for the amazing solar house. Gira(re) also means ‘to turn’ and sole is the sun, so it’s a bit of a play on words. 

Some words from the original designer, John Andriolo from MAG Constructions:

“The idea for this house came about over 50 years ago when I was just a 10-year-old boy studying history in Italy. I found Galileo Galilee’s idea of ‘eppure si mouve’ (‘the earth is moving’) completely fascinating, and since then I have always dreamt that one day I would build a house that follows the sun. Seeing this idea now become a reality is a little surreal but I hope it will demonstrate how our natural resources, like the sun and rain, can be put to good use in future home designs.”

In a world where we’re starting to see solar panels mandatory on new homes (well, in California at least) there’s no doubt we’ll start to see a lot more novel ideas.

Community Solar in Canberra – Majura Solar Farm

Investors in the Australian Capital Territory have put $3.07 million into Australia’s largest community solar project – which will be built on a vineyard in Canberra. Community solar isn’t a new thing in Australia – but it’s certainly gathering steam (or sunlight) as rising energy prices and rapidly improving solar power technology is encouraging people to invest in renewable energy.

The $3m solar plant is going to be built at the flat land at the bottom of the valley at Mount Majura Vineyard (since wine grapes are best grown on slopes this is currently unused land) and will consist of 5,000 solar panels. The Majura Solar Farm will be built over approximately three hectares and is expected to produce 1.9GWh of electricity per year, which it is planning on selling directly to the ACT government.

Lawrence McIntosh from SolarShare said that, pending approval, they are hoping to have the farm built in 2018.  The ‘SolarShare Community’ applied to sell the energy at a fixed price to the ACT government –  for $200/Mwh ($0.20 / kWh) over a 20 year period. No word on whether this is a bit hopeful but we’ll see (click here for the annual volume weighted average spot prices) how they go, given that this is the largest community owned solar plant in Australia, in terms of output. According to the Canberra Times, the feed-in tariff (FIT) amount is still under consideration. A spokeswoman from the ACT Environment and Planning and Sustainable Development was quoted as saying “The Minister for Climate Change and Sustainability will make the final decision regarding the outcome of the process”.

533 backers are part of the community solar project which comes hot on the heels of private solar investment in Australia growing exponentially over the past few months.
