    The 2015 IMC completely removed the occupancy classification of "Hospitals, nursing and convalescent homes" and its sub-catigories from Table 403.3. At the same time, Section 407 was added for ambulatory care facilities and Group I-2 occupancies, which sends you to ASHRAE 170. This is consistant in the 2018 and 2021 editions of IMC.

    What ventilation rates do you now use for medical procedure rooms (biopsy, exam rooms, dental, infusion centers, etc) or physical therapy rooms that are all classified Group B? IMC 403.3.1.1 says to pick ventilation rates that are most similar in terms of occupant density, activities and building construction; or approved engineering analysis (which I try to avoid). Do you go back one cycle? Do you go to ASHRAE 170? Do you choose a similar occupancy classification from Table 403.3 and if so, what is that classification?

    FYI, 2021 IMC will add "and NFPA 99" to the end of 407.1. These facilities will have to comply with the IMC and ASHRAE 170 and NFPA 99 !!! Won't that be fun :)

    IT seems that the IMC should have the requirements of ASHRAE 170 added to the tables if possible.

    Possibly, something akin to a small Conference Room.
