IEA SHC

International Energy Agency’s Solar Heating and Cooling Programme

The IEA Solar Heating and Cooling (SHC) Programme has over 35 years of international collaborative work in the field of research, development, demonstration (RD&D) and test methods for solar thermal energy and solar buildings.  The results of this work are available for researchers, policy makers, industry, utility and business representatives, builders, architects and teachers

The IEA SHC Programme is a member-based Programme with 20 member countries and 5 member organizations. Its mission is “To enhance collective knowledge and application of solar heating and cooling through international collaboration to fulfill its vision of solar thermal energy meeting 50% of low temperature heating and cooling demand by 2050."

  • Optimising life-cycle costs in the construction industry

    Optimising life-cycle costs in the construction industry

    A facade to capture solar energy is a particularly appealing option if a solar thermal system is to be integrated into an office or a multi-family building, as the available roof area is often relatively small compared to how much floor space needs to be heated or cooled. An international...

  • Global perspective on solar heating and cooling

    Global perspective on solar heating and cooling

    Solar thermal is increasingly used to provide district heat around the world. In 2019, the market grew by about 170 % in Denmark but also expanded in other countries, such as China and Germany, mainly because the technology became more cost-competitive. Another factor driving growth was...

  • Round robins improve TCM testing

    Round robins improve TCM testing

    Thermochemical storage materials (TCMs) offer much higher storage capacities by mass or volume than sensible or latent heat storage and can store heat for an infinite amount of time almost without losses. However, none of them are very advanced so that a common standard for characterising...
