IEA-DHC Annex TS1. Low Temperature District Heating for Future Energy Systems

The project is the Danish participation in the research project "Lov Temperature District Heating

for Future energy System" organized by the International energy Agency's District Heating & Cooking

Programme, IEA-DHC

The objective of the Danish participation is to contribute to an international development of lov

temperature district heating based on revewable energy for supply of heat to energy efficient buildings

(new and renovated). Focus will be on solutions of generic problems (design methods and technologies for

handling peak loads and critical temperatures in space heating and domestic hot water systems) that may

form the basis for new standards.

The work plan is to:

• Apply the outcome from the previous EUDP project (IEA-DHC Annex X: 4th generation district heating) to

  characterize the low temperature DH supply techniques and identify solutions for generic design problems

  to facilitate its implementation to different communities

• Analyze the technical challenges to supply the built-up area with renewable energy.

• Develop solutions for network extension and solutions to effectively use energy sources according to its

  quality.

• Identify the solutions to inhibit the growth of Legionella bacteria to safely supply low temperature domestic

  hot water.

• Explore the 100 pct renewable energy based optimal energy supply structure with the synergy between

  low temperature DH supply and building energy reduction.
