HEAT 4.0 was an interdisciplinary innovation project supported by the Innovation Fund Denmark (IFD) with 3.4 Mio. €. The project aimed at creating the next-generation digital platform for the district heating sector.

DTU Compute, DTU Management, and DTU Construct/DTU Sustain (formerly DTU Byg) were three of the 16 partners representing the whole value chain of the district heating sector.

The IFD project was carried out between 2019 to 2022, whereafter the HEAT 4.0 consortium is maintained as an open consortium, where interested district heating companies from Denmark can contact any partner to get a single point of contact. For international district heating companies, NIRAS is the first contact point.

HEAT 4.0 aims at supporting the digitalization of the district heating sector as a whole.

This includes several innovative developments and novel solutions that had to be examined in real-case setups.
For this purpose, 3 district heating companies with different setups, joined the consortium.
These cases are described in the current section. The three cases are (links go to HEATman.dk):

The first and last DH operators produce their heat themselves, while Trefor is buying their heat from a local provider. Hence solutions are adjusted to the individual case, enabling the consortium to develop generic solutions that will meet many of the existing national and international cases.

As the developments and testing at the above three cases were successfully finalized, the first commercial installations of HEAT 4.0 solutions are listed for other cases and cooperative activities involving HEAT 4.0 partners and relevant to the current consortium. Other district heating innovations were run by HEAT 4.0 partners but not financed directly under this current project – you find some of them here on the CITIES’ homepage
