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.”

How SHIP can compete with heat produced from natural gas in Europe

How SHIP can compete with heat produced from natural gas in Europe

Many studies have shown the huge potential solar thermal has for clean heat production in industry. But so far, there have been comparatively few attempts to tap into this potential, partly because of high investment costs and partly because of end customers’ lack of knowledge about, and therefore trust in, …
Germany’s solar heat success story in 2020 and beyond

Germany’s solar heat success story in 2020 and beyond

In 2020, the German market for solar heat grew by 26 % – more than any other major solar thermal market around the globe, according to the new Solar Heat Worldwide 2021 report (see chart above). Speaking at an IEA SHC Solar Academy in June, Harald Drück, a researcher at …
Global PVT market on track for more growth

Global PVT market on track for more growth

PVT collectors – which use solar radiation to produce both heat and electricity – have been gaining in popularity in a rising number of markets around the world. In 2019, the Netherlands, France and Spain claimed the top spots for the most PVT capacity added in a year. In 2020, …

Develop stable and reliable compact thermal energy storages

The IEA Solar Heating and Cooling Programme has redoubled its efforts to develop and test compact thermal energy storage (CTES), saying the technology can play an important role in transforming the energy market. At its meeting in June, the IEA SHC Executive Committee approved the start of a new research …
Workflow stories describe use of solar neighbourhood planning tools

Workflow stories describe use of solar neighbourhood planning tools

Experts working on the Solar Neighborhood Planning project have created workflow stories to find out which tools urban planners use and what problems they encounter while doing so. The image above is taken from a Norwegian workflow story. It shows a simulation of sunlight patterns during morning hours in a …
