[Bldg-sim] Green Guide for Health Care v 2.2

[Chris Jones]

Thanks Drury - that was just what I was looking for.
In particular I am interested in opinions on the following section 
from Appendix 1:
Design Assumptions & Procedures for Modeling for the GGHC Energy Credits
Ventilation, air changes and air pressure relationships: Use specific 
ventilation rates, air changes, and
pressure relationships, as required by authorities having 
jurisdiction. If the authorities having
jurisdiction have no specific requirements, use the requirements from 
2006 AIA Guidelines for Design
and Construction of Hospital and Health Care Facilities, or most 
recent version.
In particular, considering LEED EAp2/EAc1 and the modelling of the 
outdoor air flow for the Budget case, what is generally accepted as 
"the authority having jurisdiction"?  Hypothetically, could the 
hospital administrator be considered the authority having jurisdiction?

This is how the GGHC views the issued:
Process Ventilation loads: Special ventilation requirements in a 
health care facility are not unusual.
While Table OCC-1 quantifies the typical ventilation in a health care 
facility, some spaces may require
higher ventilation rates. The higher ventilation rates shall be 
simulated in both the Baseline and
Proposed building simulation runs, making this an energy neutral feature.
It would appear to me that for health care facilities, the design 
team is not constrained by the outdoor air amounts quoted in various standards.
