Dear all
I find contradiction between ASHRAE90.1-2007 Standard and ASHRAE 90.1-2007 User's Manual when deciding the baseline's HVAC system. Table G3.1.1A in Appendix G is used to decide the baseline HVAC as shown below

The note under the table which i have underline say "Where attributes make a building eligible for more than one baseline system type, use the predominant condition to determine the system type for the entire building." It seems that only one HVAC system will be used in baseline.
However, in ASHRAE 90.1-2007 User's Manual , there is no explaination about the note. While the Case Study in Page G-37 of User's Manual tell us that two different types of HVAC system should be used respectively for the Residential part and office part as shown below. So I think this conflict with the ASHRAE90.1-2007 Standard Table G3.1.1A.
what about your views?

If a hospital building includes mainly wards in 3~7 floors with an area of 132000ft2 and therapy zone in 1~2 floors with an area of 52000ft2, the proposed building is FCU served by chiller and boiler, I tend to the PTAC system (system 1) for 3~7 floors and system 5 for 1~2 floors. what about your opinion?
Thank you for any comments and directions.
