About Annex TS1

This is the first Task-shared Annex in IEA DHC history. It allows member countries and sponsors to link national research to benefit from international developments.

The IEA DHC Annex TS1 identified holistic and innovative approaches to communal low temperature heat supply. It was strongly targeted at DH technologies and the economic boundary conditions of this field of technology. The Annex TS1 was a framework that promoted the discussion of future heating networks with an international group of experts. The goal was to obtain a common development direction for the wide application of low temperature district heating systems in the near future. The gathered research which is to collected within this Annex should contribute to establishing DH as a significant factor for the development of 100% renewable energy based communal energy systems in international research communities and in practice.


Annex TS1 is finished as of December 2017. Should you have any questions you can contact the former Annex TS1 task manager:
