I have a small question regarding ASHRAE standard 170-2008.

On page 5, Table 6-1 which specifies what type of filter to be used within a health care facility, according to the different uses of spaces, and it states that "Inpatient care, treatment, and diagnosis, and those spaces....." should have a MERV 7 filter on the first filter bank, and MERV 14 on the second filter bank.

My question is does it means "Inpatient care, treatment, and diagnosis" as one type of space, or "Inpatient care", "treatment", and "diagnosis" as three separate types?

The reason I want to ask this is because we are doing a LEED HC project at the moment, but there will be no inpatient, only outpatient in the facility, so depends on the interpretation of this table, it will have very different impact on our project.

Your help on this will be very much appreciated, cheers.
