The IEA provides support for international collaboration on energy technology R&D, deployment and information dissemination. These groups function within a framework created by the IEA - the International Framework for International Energy Technology Collaboration. The views, findings and publications of these international groups (formally called Implementing Agreements) do not necessarily represent the views or policies of the IEA Secretariat or of all its individual member countries. OECD Member countries, autonomous OECD non-member countries, intergovernmental organisations, non-governmental organisations and private sector entities may participate. For more information, see our Technology Agreements page.

District Heating and Cooling including Combined Heat and Power

In operation since 1983, this Agreement deals with the design, performance and operation of distribution systems and consumer installations. With more than 80 research projects completed since its creation, the Agreement is dedicated to help make district heating and cooling and combined heat and power powerful tools for energy conservation and the reduction of environmental impacts of supplying heat.  The research addresses both technical and policy-related issues.   Annex TS1, the first task-shared annex in the DHC IA work programme, will allow its member countries and sponsors to link national research and thus benefit from international developments.

Current Projects (Annexes)

Annex X. Several DHC/CHP Projects
The following projects have been contracted under this Annex: improved maintenance strategies for district heating pipelines; economic and design optimization in integrating renewable energy and waste heat with district energy systems; towards fourth generation district heating: experiences with and potential of low temperature district heating; development of a universal calculation model and calculation tool for primary energy factors and CO2 equivalents in district heating and cooling including CHP. The Annex runs from 2010 until 2014.


Annex TS1. Low temperature district heating for future energy systems
This task-shared Annex is a co-operation platform in which national projects can be connected.
