13 Chapter 1: Heating and cooling demand in Europe addressing this information gap. A good overview of the energy use in heating and cooling was provided as the result of a tender mapping this sector and this data has been update as part of the “Heat Roadmap” Europe project. The latter also presents energy use maps for different countries as well as an interactive thermal atlas for all Europe. Looking at the split of energy use between sectors, Figure 4 shows that heating is the dominant service in residential and tertiary sectors, while process heating dominates in industry.

The current deployment of heat pumps in all sectors is far below the potential. Heating and cooling demand in Europe depends on the climate zone in combination with respective building traditions and local or national HQHUJ\HIåFLHQF\VWDQGDUGV9DULDWLRQVIURPFRXQWU\WRFRXQWU\ VLJQLåFDQWO\LQæXHQFHWKHUHSODFHPHQWSRWHQWLDOIRUKHDWSXPSV Obviously, heating demand is higher in colder climates while cooling demand dominates in warmer climates. What is not so obvious is that the number of heating degree days (HDD) across Europe are decreasing, while the number of cooling degree days (CDD) is increasing as shown in Figure 5.
