COOL DH stands for cool ways of using low grade Heat Sources from Cooling and Surplus Heat for heating of Energy Efficient Buildings with new Low Temperature District Heating (LTDH) Solutions.

The project is partially funded by Horizon 2020, the largest EU Research and Innovation program. One of the cities where the project is being developed is Lund, a member of the global network ICLEI – Local Governments for Sustainability.

The COOL DH project in Lund is run by the municipality, the utility company Kraftringen Energi and leading district heating energy specialists and industrial manufacturers. The construction started in 2018 in the new district of Brunnshög and the system will be expanded to provide heating as the area develops.

By 2050, the total development of the district will cover over 200 hectares and is expected to host 40,000 residents. The low temperature district heating network is already the largest in the world and it will expand as the district grows and the project aims to become Europe’s leading test field for LTDH solutions. The main source of low-grade heat comes from recycled fossil-free waste heat from the MAX IV facility, one of the most high-tech research facilities in the world. In the future, this will be complemented by fossil free waste heat from the European Spallation Source (ESS), currently under construction.

The construction of the district contemplates several phases. First, the creation of southern Brunnshög, which is already underway and is the entrance to the entire district. This will be followed by the development of central Brunnshög and then the construction of a science village in the area between the two research facilities. The purpose of the science village will be to support the activities of the research facilities by hosting offices and short-term housing.
