Abstract
Tunnel constructions consist of large concrete masses in good contact with the surrounding earth. The concrete shell can be thermally activated by the introduction of absorber pipes in order to obtain thermal energy from the tunnel and surrounding earth. In this way the earth can be used as a valuable energy source and the tunnel cooled economically. The energy obtained can either be sold to offset it against the costs or it can be used to heat neighbouring public buildings. The pipes are installed over the full length of the tunnel or predominantly in station areas in the case of rail tunnels, where the subject of overheating is particularly critical for the user. Energy can also be obtained from sewage or cable tunnels as in the case of metro tunnels. With limited capital costs energy tubbings offer additional advantages for tunnel operators as well as the energy supply to users above ground. (orig.)
