COOL DH Technical Workshop at EUSEW

  • Euroheat & Power Events
  • 17 June 2019 - 17 June 2019
  • Brussels, Belgium


The objective of COOL DH action is to support cities in their endeavor to plan and deploy new, efficient district heating and cooling (DHC) systems and extend, refurbish existing ones to higher standards. Thus allowing greater uptake of renewables, recovering of excess heat or cold while improving the overall efficiency of the systems.


The first European Technical Workshop took place on 17 June 2019 in Brussels. It focused both on technical and non-technical topics concerning the COOL DH innovations and the front-runner demo sites (i.e. Europe’s largest LTDH network in Lund). It allowed to make comparison with other sister initiatives (such as the TEMPO project) and share experiences and best practices.

The workshop was organised as an Energy Day in the framework of the Energy Days of the EU Sustainable Energy Week (EUSEW).



Every year the European Commission (Directorate-General for Energy and Executive Agency for SMEs) organises the EU Sustainable Energy Week (EUSEW) – the biggest event dedicated to renewables and efficient energy use in Europe. This year’s theme is ‘Shaping Europe’s energy future’ and it covers four elements across the EU: the Policy Conference, Networking Village, EUSEW Awards, and the Energy Days.
