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."
