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.
