DC 6: Energy tunnels to reduce the costs of ventilation in tunnels.

The objective of this project is to investigate the possibility to use energy tunnels to control the internal air temperature, thus limiting the ventilation costs. The solution is of interest for hot tunnels, such as deep mountain tunnels.

1. Designing and installing an experimental site in which adapted energy segments will be implemented with monitoring system. Monitoring, analysing and interpreting the measurements obtained from the experimental site.
2. Developing a numerical model, to be validated against the monitoring data.
3. Cost-benefit analysis to assess competitiveness of the technology compared to standard ventilation systems
