The Programme



The International Energy Agency (IEA) was established in 1974 in order to strengthen the co-operation between member countries. As an element of the International Energy Programme, the participating countries undertake co-operative actions in energy research, development and demonstration.

The programme

The Implementing Agreement on District Heating and Cooling including Combined Heat and Power was founded as the Implementing Agreement for a Programme of Research, Development, and Demonstration on District Heating and Cooling, including the integration of Combined Heat and Power in 1983. Ten countries participated in the first round of projects (Annex I). More information about previous annexes can be found in the DHC research section on this site.

Implementing Agreement

The Implementing Agreement on District Heating and Cooling including Combined Heat and Power, deals with the design, performance and operation of distribution systems and consumer installations. The Agreement is dedicated to helping to make district heating and cooling and combined heat and power powerful tools for energy conservation and the reduction of environmental impacts of supplying heat. This is also reflected in the IEA DHC communication strategy.

The activities

The work programme is mostly conducted through cost-shared activities. In 2014 Annex X was completed and the final reports of the projects carried out can be downloaded here (after login). At the moment Annex XI is running; information about the ongoing projects can be found under Research Projects > Annex XI as soon as the contracts are signed. In addition to the cost-shared Annex XI a task-shared Annex - Annex TS1 - is currently running. Information concerning the task-shared activities in Annex TS1 can be found here (after login).
