• 31.03.2017  Heat Roadmap Europe Workshop a success: The most detailed break-down of Europe’s energy demand for heating and cooling presented

    On the occasion of the Heat Roadmap Europe (HRE) workshop in Brussels on Tuesday 7th March, over 80 participants from all over Europe learned about the different types of heating and cooling demand and supply, the exact heating and cooling potential and where it is located. Representatives from academia, associations, the municipal sector, NGOs and the private sector gathered together for the afternoon to consider the how HRE4 results can support with solutions to decarbonise the heating sector on the local, national and European scale.
