Over 50 per cent of the emissions you produce in your home are generated by heating, air-conditioning and hot water. This is why we've invented a new solar air-conditioning system for Australian homes.

Over 50 per cent of the greenhouse gas emissions you produce in your home are generated by heating, air-conditioning and hot water.

In other words keeping your home warm in winter, cool in summer with nice hot water on tap is emitting 2.5 to 5 tonnes of greenhouse gas emissions each year.

It also contributes a hefty amount to your electricity bill, between 50 to 60 per cent.

CSIRO has invented a new solar air-conditioning system for Australian homes. This technology solution will reduce Australia’s emissions, reduce your energy bills and reduce our demand for electricity and gas.

It is an innovative three-in-one technology that provides hot water, cooling and heating.

It works by using heat from the sun and employs both desiccant and evaporative cooling technologies.

Solar heat is first collected and stored as hot water, which can be used directly in the house. A portion of the hot water is diverted into the solar air-conditioning unit, which is used to either heat or cool the air coming into the building.

Our solar air-conditioning system uses only a fraction of the electricity of current air-conditioning systems and halves greenhouse gas emissions.

The video below explain how solar air-conditioning works or you can go to www.csiro.au/solar-cooling for more info.


  1. HI Ms/Mr. Steph Overton, does it operate on solar panel? what kind of solar power system it uses? It seems it will be a promising form of renewable source of power for HVAC system.

    1. Hi there,

      Yep, the system operates on energy from solar panels. The panels we use are solar thermal ‘flat plate’ collectors which capture heat from the sun for use in our solar cooling system.


  2. I would like to install this system in our new resotel under construction in Thailand; you can use/monitor performance for using the system in tropical climate. Can become win-win situation.

  3. Hi

    This is interesting for tropics. We are at India offering solar based cooling solutions for large projects based on VAM. We would be keen to know more about your solutions , if it is available in commercial domain and what plans you have for Indian market.

    1. Hi there,

      Unfortunately the technology is not yet available in the commercial domain. After testing is complete we’ll look at options for commercialisation in the Indian market.


  4. I would like to put this system in my home in woodlands Perth I am an electrician/builder and would be able to install myself let me what you think.wayne cheers

  5. It’s an impressive system. When is it commercially available?

    1. Hi Graham,
      The technology is currently being trialled in select residences. Within a few years you might even have one of these systems in your own house!
