The overall impact of Upgrade DH is significant. The proposed measures for upgrading lead to a reduction of 16.9% of the primary energy demand and 51.9% reduction of greenhouse gases of the DH systems at the eight demo sites. In absolute numbers, this is a reduction of more than 150,000 t of CO2 equivalent per year. Furthermore, the share of using waste heat increased by 3.3% and the share of renewable energies increased by 21.7%. Several of the upgrading measures are currently being implemented, some measures were even finalised. The Upgrade DH project has managed to raise very significant interest at EU level amongst key members of the DHC industry. Whenever abstracts were submitted to important conferences (e.g. Smart Energy Systems Conference, EUBCE, IEA Symposium), they were accepted and presentations showed a high degree of participation and engagement. The potential for replication has repeatedly been highlighted as a key factor to increase impacts in the medium run and the pragmatic and holistic approach regarded by third parties as a key strength of the project.
