A platform of networking and knowledge, CELSIUS takes a holistic approach to overcome technical, social, financial and political barriers to district heating and cooling solutions. Read more about CELSIUS or watch a film.

We have surpassed our goal of signing up 50 CELSIUS member cities! We now open up the CELSIUS network to other district heating and cooling stakeholders: the CELSIUS City Supporters. Find out more in the short information film below.

EU Heating and Cooling Strategy

On 16 February, the European Commission launched its first ever strategy to tackle the massive use of energy, particularly fossil fuels.

Heating and cooling accounts for 50% of the EU’s energy consumption and renewables account for just 18% of this. The strategy includes plans to boost the energy efficiency of buildings, improve linkages between electricity systems and district heating systems which will greatly increase the use of renewable energy, and encourage reuse of waste heat and cold generated by industry.

Past Workshops and Events

At the Smart City Expo World Congress in Barcelona on 17 – 19 November, Katrina Folland, CELSIUS Coordinator, and Emilia Pisani Castañeda, CELSIUS Project Officer, received the World Smart City Finalist Award, recognizing pioneering smart Projects to aid cities in becoming more sustainable, efficient, economically viable and livable.

The CELSIUS Toolbox

The CELSIUS Toolbox/ wiki was launched on 22 March. Here you can view the CELSIUS Talk of this event.

District Heating and Cooling

District heating is a heating system consisting of a pipe network, filled with hot water, and heat sources (from residual heat or a heating plant). The hot water is circulated by pumps, from the heating plant to the client and back again to the heating plant. A heat exchanger at the customer transfers the heat from the district heating network to the building’s own heating and hot water systems. The return water continues out through the return pipe and is pumped back to the heating plant, where it again is heated.
