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.

The CELSIUS Wiki is an online district heating and cooling knowledge resource that is growing as more representatives join the CELSIUS network and contribute.

The goal of signing up 50 CELSIUS member cities is surpassed! The CELSIUS network now welcomes more district heating and cooling stakeholders: the CELSIUS City Supporters.

CELSIUS is nominated to the EUSEW Award!

The EU Sustainable Energy Awards recognise outstanding innovation in energy efficiency and renewables and highlight new ways to shape Europe’s energy future. Twelve finalists across four categories are on the shortlist of the year’s most successful projects for clean, secure and efficient energy. A high-level jury decides the winner in each of the categories – Businesses, Public Sector, Consumers and Energy Islands.

A public online vote will determine the winner of the 2017 Citizens’ Award. You can cast your vote for CELSIUS here!

EU Heating and Cooling Strategy

On 16 February, 2016, 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.

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.
