The Solar Heating and Cooling Programme was founded in 1977 as one of the first multilateral technology initiatives (Technology Collaboration Programmes) of the International Energy Agency. Its mission is “to enhance collective knowledge and application of solar heating and cooling through international collaboration to reach the goal set in the vision of solar thermal energy meeting 50% of low temperature heating and cooling demand by 2050.

The members of the Programme collaborate on projects (referred to as “Tasks”) in the field of research, development, demonstration (RD&D), and test methods for solar thermal energy and solar buildings.

The Institute’s distinctive transversal themes are:
- decentralisation of electricity production from renewable sources (photovoltaics)
- decarbonisation in the built environment and in mobility
- digitalisation in electricity management (smart grids), and in building construction and maintenance procedures (Building Information Modeling
- democratisation of energy by way of the prosumer, and involvement in technological choices and in their utilisation in real-life conditions (living lab)
Research projects are based on a variety of regularly-revised methods, and benefit from productive collaboration agreements with other research units, public bodies, non-governmental organisations and industries. The Institute promotes technological transfer in a number of developing countries.
