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?

Mixed-Mode Ventilation in Residential

I'm working on a residential project hat has mixed-mode ventilation, partial mechanical and operable windows in units. What are the requirements in terms of CO2 and OA sensors for mixed-mode ventilation? Also, do CO2 monitors need to be wired to the BMS? Thank you

If you are using mixed mode, then you should comply with both requirements for natural and mechanical monitoring (AFM and CO2). The sensors are not required to be wired to the BAS as long as they provide an alarm to the building occupants.
