Sharing knowledge for energy-efficient heating and cooling

The CELSIUS project is making it easier for local authorities and energy companies to develop energy-efficient district heating and cooling systems. It brings together 65 European cities, along with supporters from industry, other EU-funded projects, academia and special interest groups, to share knowledge, promote relevant EU legislation and advise each other on setting up these systems.

District heating and cooling systems are a sustainable, low-carbon way of keeping buildings comfortable and providing hot water. They distribute centrally-generated heat around an area’s buildings through a network of pipes. When that heat is waste heat from industry or urban services such as metros, or generated from renewable energy, it is clean and efficient.

Participants in the project develop and share technologies for generating, delivering and managing the heat. They also inform the European Commission on how to legislate so that district heating and cooling systems compete on equal terms with other solutions, and advise one another on raising finance for new systems. Around 40 million citizens live in the cities included in the project, all of whom could benefit from energy-efficient, sustainable heating and cooling. 

CELSIUS is already playing a major role in helping the EU it achieve its goals for low-carbon, competitive, smart cities. Projects to test technologies in partner cities have cut Europe’s CO2 emissions by almost 100 000 tonnes per year. The network is still growing, and project members and supporters remain in close contact through seminars and conferences, a CELSIUS LinkedIn group, and a dedicated wiki.

Other participating cities: London/Islington Borough, Cologne, Rotterdam, and Genoa.
