TEMPerature Optimisation for Low Temperature District Heating


October 2017 to March 2022


The technical and economic viability of today’s district heating networks are undermined by transitions to highly efficient building stocks and ineffective business models which fail to benefit all stakeholders.


TEMPO demonstrated the applicability of low-temperature district heating through a COMPREHENSIVE SOLUTION PACKAGE that includes technological innovations on the network and building side, consumer empowerment enabled by digital solutions and innovative business model for EU replication.

More specifically, the main objectives of TEMPO are:

  • Final development of technological innovations for low-temperature (LT) district heating (DH) networks.
  • Quantify the benefits of the TEMPO solution packages for LT DH networks through demonstration in 3 representative demonstration sites.
  • Empowerment of end users in LT DH network.
  • Develop innovative business models and demonstrate their replication potential for the roll-out of sustainable and economically viable DH networks across the EU.
  • Guarantee EU-wide market uptake of TEMPO solutions packages by developing an exploitation and replication plan.

Technological innovations implemented at the two demo sites:

  • A supervision ICT platform for detection and diagnosis of faults in DH substations
  • Visualisation tools for expert and non-expert users
  • Smart DH network controller to balance supply and demand and minimise return temperature (i.e. STORM controller)
  • Innovative piping system
  • Optimisation of the building installation
  • Decentralised buffers at the consumer side 


  1. The Enerpipe demo is a new rural LT network situated near Nuremberg, Germany
  2. The A2A demo is an existing network of currently operating at a HT, situated in Brescia, Italy
