[Dennis La Touche]

Thank you, I couldn’t find that CIR, does it apply also for hotel buildings?

I had a similar scenario with patient rooms in a hospital recently.  I
submitted the same question to GBCI, and the response was that I have to use
0.3 W/cfm per CIR dated 8/13/2007

adjustments-

 

I have a question, for hotel buildings the baseline HVAC system type to be
used should be PTAC/PTHP (ductless).

 

This proposed building will be composed by a chilled water system with air
handling units and fan coils, all of them fully ducted return.

 

Is it possible to use the fan power limitation pressure drop adjustment
indicated in ASHRAE 90.1 for increasing the baseline fan power?

 

The question is because in G3.1.2.9 it seems that it is only allowed for
systems 3 through 8.

 

Thanks.

 

 

Dennis
