Hotel Milano Scala has recently installed a new Mitsubishi Electric filtration system. Fresh air entering the interior spaces is treated in four air handling units — three rated at 5,000 m3/h plus one at 10,000 m3/h for a total air treatment capacity of 25,000 m3/h — composed of a class G4 pre-filter and a class F9 final filter (the same ones used in hospitals to prevent contamination).
Ventilation systems designed for office buildings may recirculate most of the air and only supply a small percentage of fresh air, but architectural and building codes require that laboratory rooms and vivaria use only fresh outside air for ventilation. This design difference explains why laboratories require so much more energy to operate.
