Heat Roadmap Europe 4

The aim of Heat Roadmap Europe 4 (HRE4) was to create the scientific evidence required to support the decarbonisation of the heating and cooling in Europe and redesign this sector, by combining the knowledge of local waste heat conditions, potential savings and energy system analysis.



March 2016 to February 2019.


Description / Objectives:

In Europe, there is a clear long-term objective to decarbonise the energy system, but it is very unclear how this will be achieved in the heating and cooling sector. As a result, there is currently a lot of uncertainty among policymakers and investors in the heating and cooling sector, primarily due to a lack of knowledge about the long-term changes that will occur in the coming decades. HRE4 aimed at enabling new policies as well as preparing the ground for new investments by creating more certainty in relation to the changes that are required.


Since heating and cooling are inherently local, but represent the largest single sector of the European energy system, this has required highly localised data through energy mapping; national modelling and Heat Roadmaps, bottom-up European-wide technology and stock knowledge, and guidelines at all levels.

HRE4 Countries:

HRE4 covered the 14 countries in the EU ranked largest by heat demand. This means that with these 14 countries, the project covered 85-90% of the heating and cooling demands in Europe, which makes the HRE4 results hugely relevant for the EU level.
