EnergyMentor in the LIFE24-CET-IncentEU Project
Accelerating low-temperature district heating & cooling across Europe.
IncentEU LIFE (2024–2027) is an EU-funded initiative accelerating the adoption of modern low-temperature district heating and cooling systems across European municipalities.
EnergyMentor supports the project as a technical partner, contributing expertise in hydraulic modelling, network optimisation, system design, and engineering analysis for scalable DHC development in the Baltics and Nordics.
Our role includes:
• developing engineering and hydraulic reference models;
• analysing municipal energy scenarios and DHC integration potential;
• supporting replication activities in partner cities;
• contributing to guidelines and engineering frameworks for future low-temperature networks.
The project is coordinated by Aiguasol and co-funded by the LIFE Clean Energy Transition Programme of the European Union.
Project ID: LIFE24-CET-IncentEU — 101215745
Duration: 2024–2027
Total budget: €2.93 million
EU contribution: €1.76 million
Coordinator: Aiguasol (Spain)

Project details:
Project number: 20.1.01.25-0988
Funding programme: RRF 1.1.22 – Construction Digital Leap (Ehituse e-hüpe), 3rd call
Field: Development of e-construction (national level)
Total project budget: EUR 50,000
EU funding: EUR 25,000
The project is supported by the Recovery and Resilience Facility (RRF).

PROJECT OUTCOME

The project resulted in an AutoCAD add-on designed to digitalise and streamline district heating network design and engineering workflows.

Key development areas included:
• BIM-based representation of district heating pipelines
• Automated creation of BIM and 3D network models
• Generation of longitudinal pipeline profiles
• Automated material quantity calculations
