5. • What do we understand when we talk about “circularity”?
• EU COMs and legislative proposals on Circular Economy define circularity recycling rate.
Recycling is here the share of recycled materials in End-of-Life waste.
• However, circularity should not only refer to material use but also include
energy resources.
Figure 1: Shows the metabolism of Austria in 2014, includingextraction,net imports, material- and energetic use as well as domestic processed output (DPO), vapor,
carbon as well as recycling (Jacobi et al., 2018). Source: Jacobi, N., Haas, W., Wiedenhofer, D., Mayer, A., 2018. Providing an economy-widemonitoringframework for
the circulareconomy in Austria: Status quo and challenges. Resources, Conservation and Recycling 137, 156–166. https://doi.org/10.1016/j.resconrec.2018.05.022
• Trade-offs between material
use and energy use as well as
rebound effects can be
depicted;
• Substitution effects of fossils
with renewables can be shown;
• Allows for more accurate
assessment of circularity based
on the overall material and
energetic throughput (e.g. for
biomass and fossils)

6. Europe consumes half of its
energy for H/C purposes. Most
in buildings and industry

7. Most thermal energy is produced
from fossil fuels (66%) and only
13% comes from renewable
energies

8. There is more heat wasted
during electricity production in
Europe than is required to
heat all buildings in the
continent
Heat demands: 1,529 PJ/y
Excess heat: 2,470 PJ/y
District heating share: 12%
Renewable energy in
heating: 12%
Not a technical barrier to
improve energy efficiency

The heating and cooling sector can play an important role by integrating the
increasing shares of variable renewable energy and enhance the grid
flexibility.
4
In the vast majority of urban areas, district energy is technically and
economically more viable than other network and individual based solutions,
and can be 100% decarbonised through the use of renewables, large heat
pumps, excess heat, and cogeneration.
2
Energy efficiency on both the demand and the supply side are necessary to
cost-effectively reach the decarbonisation goals.
1
The heating and cooling sector can be fully decarbonised based on
technologies and approaches which already exist, are market-ready and
have successfully been implemented in Europe.

District heat supply
• Different types of heat start to
play a different role
• CHPs operate to the
electricity markets and ‘pair’
with large heat pumps
• HPs combined: ~75%
• Individual boilers are almost
irrelevant
• Constraints are mostly
temporal and geographic

13. Specific (sub)sectoral targets and
horizontal and vertical integration
• EE and RE go hand-in-hand but need to have seperate targets
• EE transistion costs are lower and affordable if the energy system is
optimised locally, regionally and across-boarders
• Horizontal integration of EE targets: Overall EE target should be translated
(in NECAPs) into all sectors (electricity, heating and cooling, transport etc.)
and their subsectors.
• Vertical integration of EE targets: throughout governmental levels

14. Panel Debate
Technical options for heat transfer, infrastructure and development and how to address
user psychology, legislature, incentives and costs
