FAQs about IEQc1 :

If my project is using air handlers that supply 100% outside air at a constant volume, do I still need to install an airflow monitoring device?

Dear all, We are working with a project that have a densely occupied meeting room. The walls of this room do not go from floor to ceiling and the room is located in a not densely occupied open office. Do we need to install CO2 sensors? Thanks in advance, Anderson Letti

How tall are the walls and what is the ceiling height?

Andrew, The wall height is 1.8 m / 6 ft, and the ceiling height 3.3 m / 11 ft. Are the CO2 sensors required?

Since you are enclosing the entire breathing zone (up to 72") as defined by ASHRAE 62.1, my interpretation is that you need to have CO2 sensors.

Dear Andrew, For another project we have a different scenario now. The meeting rooms (densily occupied) located in the open office area (no densily occupied) have only three walls, going from floor to ceiling, with one side open directly to the open offices. Do we need to install CO2 sensors in the meeting rooms? The project is mechanically ventiladed. Best, Anderson Letti

I would consider it one space. Calculate the density based on the total area and total occupants. If it is less than 25/1000sf, then you should be safe without it.
