Dear all,
I understand that LEED doesn't require you to specify a maximum CO2 level for this credit. The requirement is to monitor whatever the design CO2 level is, and make sure it doesn't vary by more than 10%.
That being said, can anyone advise of a typical CO2 design level for a Food Court area and a circulation area?
Many thanks,
Jean Marais

Are you sure the circulation area needs to be monitored? It's not regularly occupied space where there are people working, is it?
Usually 800-1000 ppm are normal upper bounds. Depends on the outside air condition as well. I think the difference becomes important. I read a good article in ASHRAE Journal on this, but can't remember for sure what the numbers were. Outside normal is about 400 ppm as the standard. 600 ppm would be for offices if the outside is at 400 ppm (I think)...is there not something in the ref guide about this?
