tank-farming activities. The reason for this is that significant amounts of heat can be
exchanged with the tunnel environment and the surrounding ground. This heat
exchange can be particularly favourable especially when tunnels are characterised by a
significant length or high traffic, and when they are constructed at significant depths
or in locations where noteworthy geothermal gradients are present. The use of energy
