The ventilation design of a metro or railway tunnel system requires broad know-how in various fields: from profound knowledge in aero- and thermodynamics and the capability to perform simulations of complex tunnel systems to the implementation of the design into operational, reliable ventilation systems.

Design of the tunnel ventilation system

HBI Haerter Consulting Engineers conduct detailed analysis of aerodynamic coefficients of a tunnel, the ventilation system and the sensing elements. This is the foundation of the control and monitoring concept. The control usually includes following conditions:
Normal operation, for example unidirectional traffic, special case, for example oncoming traffic, event of fire and evacuation, event of fire and firefighting.
