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?

NC-2009 IEQc1:Outdoor Air Delivery Monitoring

Airflow measuring devices

Hi, In order to file compliance with IEQP1 & IEQc1: does the Airflow measuring devices need to be connected to BMS? Can they be standalone and programmed to generate an alarm?

Local alarms are allowed. Alarms should alert building occupants.

Hi Andrew, Thanks, can I clarify 2 more items: 1)if a meeting room is served by a dedicated FCU; Does the meeting room require both the airflow measurement device as well the CO2 sensors or just the CO2 sensor will do? 2) We have CO2 sensors in the return air duct that modulate the airflow based on occupancy. When there is less/no occupancy if modulates the damper to close In order to save energy. Now when we program the airflow device serving the same space to maintain a minimum airflow, it does not complement each other. As airflow devices are programmed to maintain a minimum airflow even with no occupancy. How to resolve this?
