    Excess heat from energy-intensive industries is often suitable for use in district heating systems but is usually unutilized. A detailed overview of the potentials available in the EU is now provided by a database of the sEEnergies project. In Germany, 29 petajoules of excess heat from industrial sites could be used, which corresponds to the demand of more than half a million households. The information is available as maps and downloadable datasets.

Final conference of the H2020 Hotmaps project presents an open data toolbox


“Heating and cooling planning for greener cities: local resources first” was the topic of the final conference of the Hotmaps project. The event took place entirely online and included different plenary and parallel sessions. Around 70 people remained online all the time.

The HotMaps project designed a toolbox for the EU28 to support public authorities, energy agencies and urban planners with strategic heating and cooling planning on local, regional and national levels in line with EU policies. Fraunhofer ISI developed an open-source industrial database that identifies industrial excess heat potentials for energy-intensive industries and provides load profiles for the heating demand of all sectors. Together with the heating density in the toolbox, this makes it possible to assess the match of future heating demand and supply at hectare level.

In the final conference, the toolbox was presented and it was demonstrated how the different stakeholders involved in heating and cooling (H&C) planning can use it in their daily work:

  • City planners can use it as a data-driven decision-making tool, to support the development of Sustainable Energy and Climate Action Plans and to engage with stakeholders, making it possible to speed up the process.
  • Consultants can use it as a source of open data and source codes for their own tools and as a calculation tool to perform studies for clients in the EU 28.
  • Utilities can use it as a tool to identify potential areas of interest for projects and to perform pre-planning studies to be sent to potential customers as well as a platform to share common data with stakeholders.
  • Researchers can use it as a resource center for data and methodologies to produce knowledge, and as a development platform for further projects.
