Most public buildings rely on air handling units (AHUs) to provide a continuous supply of clean and comfortable air. In medical research facilities, they are especially critical to maintain optimal laboratory environment conditions. Medical research can be very temperature sensitive and any unplanned downtime can cause millions of dollars in damage and destroy years of research. At one Canadian facility, after a recent incident, the facilities management team began searching for a solution to protect valuable research, prevent a re-occurrence and eliminate problematic downtime.
