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)

• 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
slide 10
INTERNATIONAL ENERGY AGENCYDistrict 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.
