District Heating and Cooling, including the integration of CHP
The goal of the project is to bring experience, knowledge and solutions for the 4 th
Generation District Heating systems to a level where they are ready to be implemented
widely.
• Phase I: document experiences in mature DH countries with very low temperature
systems serving highly energy-efficient new-build developments
• Phase II: analyze and extend the scope of lessons arising from early examples of low-
temperature systems, in order to improve the cost-effectiveness and environmental
benefits, effectively formulating a blueprint for a new generation of district heating.

High Grade Resources
• Have reliably high temperatures that always exceed the DES supply temperature, and
can be used directly whenever it is available.
Low Grade Resources
• Have lower temperatures that are sometimes or always insufficient relative to the
DES supply temperature but always sufficient relative to the DES return temperature.
• If the temperature of the source falls below the DES supply temperature, the
temperature must be polished with other energy sources.
Below Grade Resources
• Always have temperatures lower than the return temperature in the DES, and must be
upgraded with a heat pump.
Renewable Energy & Waste Heat (REWH)
INTERNATIONAL ENERGY AGENCY
District Heating and Cooling, including the integration of CHP8
• At what temperature is the
Renewable Energy or
Waste Heat (REWH)
available, and how does it
compare with the supply
and return temperatures
of the DES?
• Representative resource
temperatures (at left), with
heat pump increase
shown in grey.

• Tools for obtaining actual technical status of pre-
insulated bonded pipes in operation
• A model for decision making regarding actions to be
taken based on– Technical status– Forecasted operational parameters– Requirements on robustness & redundancy– Costs for energy loss, maintenance &
reconstruction
• Predicted degradation & remaining technical life based
on– Accelerated aged pipes– Pipes from field operation– Synthesis of available studies
Objectives of project

District Heating and Cooling, including the integration of CHP
• The accelerated ageing of pipes with both a
standard and a thinner casing is continuing.
• The pipes are exposed to an ambient temperature
of 70°C. The service pipes are kept at four levels:
70°C, 130°C, 140°C and 150°C
• Hence, accelerated ageing cause both deterioration
of PUR at service pipe and deterioration of
polyethylene casing.
