Lund Municipality, Kraftringen: COOL DH - low temperature district heating
COOL DH is an EU project aimed at optimising the use of low-temperature district heating. In the project, a number of Swedish and Danish partners worked on solutions for low-temperature district heating with the aim of promoting a more resource, energy and cost efficient district heating supply for the sustainable cities of the future. The project was completed in autumn 2022 and has a strong connection to the low-temperature district heating network that Kraftringen is building in Brunnshög.

COOL DH-the project worked on innovating, demonstrating, evaluating and disseminating technical solutions needed to use sources of very low-grade excess heat for heating energy-efficient buildings via low-temperature district heating. The project shows how the transition to low-temperature district heating can be made in a resource-efficient and energy-efficient way.
The goal of the COOL DH project was to develop and test new solutions and support cities in their endeavors, both in planning and deploying new, efficient district heating and cooling systems and in order for them to expand and renovate existing systems to higher standards. This could allow a greater use of renewable energy sources and the recovery of excess heat or waste cold. At the same time, the intention was to improve the overall efficiency of the systems.
COOL DH was funded under the Horizon 2020 programme and a number of Swedish and Danish partners worked on the project. The cities of Lund in Sweden and Høje-Taastrup in Denmark participated in the project.
The project has a strong connection to “the world's largest low-temperature district heating network” — the district heating network being built by Kraftringen on the Brunnshög area in Lund. In this work, residual heat from the MAX IV research facility is used, and for the new district heating network, the project has, among other things, developed new and simpler distribution pipes for use in Lund and Høje-Taastrup.
- As there is recycled heat in the new district heating network at Brunnshög, it has a very good environmental performance, says Markus Paulsson at Lund Municipality. This, together with a new pricing model that prioritizes efficient heat use, has led most of the new houses on Brunnshög to connect to district heating. For the city, it is also positive that the new pipes can be laid in smaller shafts, which makes it faster to lay the pipes while taking up less space.
