The process leading to the realisation of a sustainable and smart heating and cooling project shows a great variance from city to city, district to district. Taking this into consideration, Celsius provides demand driven support actions for cities looking to decarbonise their heating & cooling systems while supplying affordable comfort to its citizens.
As a demand-driven collaboration hub we gather and share knowledge through our Toolbox, newsletter, webinars and various events. Moreover, we connect the members of our network to foster innovative solutions and influence European policy. Join us!

"The Toolbox is user-friendly with high quality"
Celsius Toolbox: an interactive knowledge-transfer platform for heating and cooling solutions.
A fast track for research and innovation
The largest network within heating and cooling offer powerful solutions for your tasks.
We create demand driven Forerunner Groups
We match cities based on their perceived issues and problems so they can jointly find solutions.

Give cities a voice in Brussels
No energy transition without sustainable cities; no sustainable cities without sustainable heating and cooling. As the 2016 European Commission’s Heating & Cooling Strategy made clear, district energy systems will have to play a significant role to make Europe’s broader climate and energy ambitions a reality. And cities will be in the driver’s seat to make a successful energy transition happen.

Celsius Summit 2018
The yearly conference of the Celsius Initiative took place in Brussels in October 2019 and included a summary of the successfully implemented project Fossil-free Energy District (FED).
Heating and cooling will play a decisive role in the long-term decarbonisation of Europe’s energy system: the sector is responsible for 51% of final energy use in Europe and about 27% of CO2 emissions.
Solar thermal energy is becoming increasingly efficient and affordable. This zero-emission renewable resource playing a vital role in the energy transition in Europe.
