[Bldg-sim] Acceptable CO2 levels

Amit,

Healthcare facility ventilation requirements are often determined using the AIA/FGI Guidelines for Design and Construction of Health Care Facilities (full APA reference below), Table 2.1-2 (attached); not ASHRAE Standards. This table sets forth strict minimum outdoor air change per hour requirements for critical spaces (operating rooms, patient rooms, etc.). These outdoor air rates cannot be modified based on the CO2 levels in the zone.

AIA. (2006). Guidelines for Design and Construction of Health Care Facilities. Washington D.C.: American Institute of Architects.

Hi all,
This question is not directly related to the group but i wanted to  throw it in as many of you might know the answer.

What is the acceptable CO2 level for a healthcare facility? Can i find the number in any ASHRAE standards?
