Baseline HVAC system and envelope for hospital patient rooms

I'm not sure of the Baseline envelope and HVAC system to use in hospital patient rooms. For one, Section 3.2 defines "residential" as including patient rooms in hospitals. If you believe this, then do you have to model patient rooms in your Baseline model with Residential envelope as defined in Table 5.5-x? This would require one type of Baseline envelope for patient rooms, and another type for non-patient rooms. And do you have to model the Baseline HVAC systems for patient room thermal blocks using a residential system, such as System 1 or 2 in Table G3.1.1A? The footnotes to Table G3.1.1A do not refer to patient rooms as "residential," but Section 3.2 does. Also, while exception 'a' of G3.1.1 prescribes different Baseline systems for Residential areas (System Type #1 or #2), exception 'c' prescribes that System Type #3 or #4 be used for areas with code-required minimum circulation rates, which pertains to patient rooms as well. If you believe that it is appropriate for the Baseline to have a Residential HVAC System type, it appears that the Proposed model will be unfairly penalized since G3.1.2.9 does not allow for a Pressure Drop Adjustment 'A' for System Type #1 or #2. I would appreciate your input and experience as to the appropriate Baseline envelope and HVAC systems to use for patient rooms in hospitals.
