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

Doctoral Candidate

Mattia Garza

Bio

I am a Civil Engineer from Italy, with a Master’s degree in Geotechnical Engineering from Politecnico di Torino. Towards the end of my studies I developed a growing interest in research, and in particular in energy geostructures: the idea that what we build underground can do more than carry loads.
What motivates me is sustainability in the construction sector. Infrastructure is built to last for decades, and I believe it should be designed to give something back, helping to make our energy systems cleaner and more efficient. My PhD within the GENIUS network is my opportunity to pursue this idea, applying it to tunnels.
I am a curious person: I like to understand how things work before trying to solve them, and I enjoy breaking complex problems down into smaller, manageable steps. I believe good research is a collective effort, so I value teamwork, open discussion and learning from people with different backgrounds and perspectives, which is exactly what an international network like GENIUS offers. I see these three years as a chance to grow not only as an engineer, but also as a person.

Aim

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.

Specific Objectives
  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
