Ductwork and envelope leakage diagnostic, impact analysis and improvements in an airport control tower

Purpose of the work

In an air traffic control tower, conditions for thermal comfort are crucial as the task of air traffic control requires high level of attention and vigilance. Comfortable conditions must be guaranteed all the time especially during extreme periods. Therefore, the HVAC system of a control tower is always composed by two, possibly three, identical air handling units, functioning in full redundancy.
