Programme of Research, Development and Demonstration on District Heating
IEA's Programme of Research, Development and Demonstration on District Heating was
established in 1983 at a meeting in Stockholm.
Annex I
In the first phase (Annex I), ten countries took part in the programme;
- Belgium
- Canada
- Denmark
- Federal Republic of Germany
- Finland
- Italy
- The Netherlands
- Norway
- Sweden
- USA
The National Energy Administration, Sweden, has been the Operating Agent for the first
Phase, in which the following technical areas have been assessed:
- Heat Meters
- Cost Efficient Distribution
- Heat Production
- Use of Low Temperature Heat Sources in District Heating Systems
- Conversion of Building Heating Systems to District Heating
A Summary Report of all research activities carried out under Annex I in the period between
November 1983 and December 1987 was published in 1988 by the National Energy Administration Sweden
(report Statens energiverk; 1988: R16).
Annex II
In 1987 Annex II was started up. Under that Annex the following technical areas have been included:
- Consumer installations
- Piping
- Advanced Fluids
- Heat Meters
- Advanced Heat Production Technologies
- Thermal Energy from Refuse.
The Netherlands Agency for Energy and the Environment (NOVEM) has been acting as the Operating Agent for Annex II.
Nine countries have participated in this Annex, i.e. all countries of Annex I except Belgium.
The Summary Report of all the research activities carried out in the time period between
May 1987 and November 1990 was published in 1990 by NOVEM (Report NOVEM 1990 R-12).
Annex III
In May 1990 decisions were taken about an Annex 111, in which all participants of the second Phase continued their participation for
another three-year period. Items for Annex III were:
- R&D Project Review
- Promotional activities
- Piping Techniques
- Consumer Heating System Simulation
- Supervision of District Heating Networks
- Advanced Transmission Fluids
Also for this Annex the Netherlands Agency for Energy and the Environment (NOVEM) has
been acting as the Operating Agent. The report you are reading, contains the summaries of all
research activities carried out between May 1990 and November 1993.
Annex IV
In May 1993 it was decided to continue the activities; Annex IV was started up.
In Annex IV all countries of the third Phase participate, except Italy. In 1994 Korea decided to take part
in the programme. The Executive Committee decided upon the following items for the programme under Annex IV:
- Design guide for integrating District Cooling and combined Heat and Power
- Advanced Transmission Fluids
- Piping Technology
- Supervision of District Heating networks
- Efficient substations and Installations
- Development of longterm cooperation with East European Countries
- Temperature variations in preinsulated district heating pipes, Low Cycle Fatigue.
Again the Netherlands Agency for Energy and the Environment (NOVEM) will be acting as the Operating Agent.
Available Budget
The total budget for Annex I was US $ 525,000. For Annex 11 a budget was available of US $ 675,000.
For Annex III a budget of about US $ 1,000,000 has been agreed by the participating countries.
For Annex IV the preliminary available budget amounts to approx. US $ 1,250,000.
