RELaTED – Development schemes for new district heating developments (2.5)

Share this Post:

This report (D2.5) is one of various RELaTED reports describing low temperature concepts from different perspectives. The report refers to other RELaTED reports when relevant.


The guidelines of this report are in general terms, based on best practice as most new urban development areas are different in relation to visions, DH network topology, temperature levels, buildings installations, tariff structure, management etc. In Annex 1 an example from Vinge, Denmark is used to illustrate and detail some of the paragraphs of the report.


The guidelines are concerning the following topics: Strategic and integrated energy planning for new developments areas. What is the vision and the strategy for the development of the DH system and how is it integrated in to the overall planning of the development area. For the DH supplier the economy focus is on investments, operation expenses and how this compares to the possible income from heat sales. For the customer this can be in the relation to which heat source is chosen for a new building or in relation to the energy costs. The impact on the society will rely on a socio- economic analysis.


The objective of task 2.5 is to develop a set of guidelines for low temperature district heating in new urban environments. The guidelines will focus on energy planning and economy, network topology, scenarios for timeline and energy sources, necessary measures for implementation, project developments and operation and management.


The possible topology of a future DH network will have an impact on whether the heat sources will be individual, decentralized DH system or centralized DH system. Pros and cons are considered for these systems.


Appropriate implementing measures, which include the delivery conditions as well as the technical building systems specifications for ULT DH, are considered. Tariffs and building regulation integration can support the concept as well.


Project developments will cover which parties have which responsibilities in the process, how the information flow affects the process, the need for support and follow up in the process.


The guidelines will be used in the succeeding work packages of RELaTED to investigate further the architecture of the ULT concept (WP2), design and adaption of subsystems to facilitate the use of distributed energy resources (WP3), analyse the economic feasibility and business case (WP4) and prepare and conduct demonstrations (WP5), of the RELaTED project.
