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?

Hi, We are working on a six story residential project. Each unit is cooled by ducted water source AC unit. AC unit does NOT have outside air connected to it. We are delivering pre-cooled outside air in the corridor of each level. This pre-cooled air will be transferred into each residential unit via 3/8" entry door undercut. Residential unit has toilet and dryer exhaust system, which works as "Push-Pull". Thus, there will be a continuous exhaust in the space 24/7. This will pull pre-cooled make up air from the corridor via door undercut. Could we qualify this design as "Mechanically Ventilated" space?

You can, but be sure to have the exhaust running any time the room is occupied. Also, be sure to use the correct ventilation effectiveness fraction. If the exhaust is near the front door it will likely be 0.5. That means you will need to supply twice the calculated amount using area/occupant calculation.
