[Bldg-sim] Acceptable CO2 levels

[James V Dirkes II, PE]

Dear Amit,

 

Keep in mind that ASHRAE's "acceptable" level of CO2 has almost nothing to
do with health.  You could describe it as more of a "body odor" or
"pleasantness" index.  When the ambient levels of CO2 exceed their
recommendation (~1000 ppm), people start to feel that the indoor air is less
pleasant or "stuffy".

 

Health does not start to be affected until CO2 exceeds 5000 ppm. (per US EPA
and ACGIH)

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?

Thanks

Sincerely,
Amit Bhansali, M.S. , EIT
