We have a lab classroom building that is served by an 100% OA unit. It maintains 6 ACH in all the lab spaces for ventilation while in use.

According to IEQc1, I am to complete table IEQc1-2 for all systems where 20% or more of the design supply airflow serves non-densely-occupied spaces.

We are currently working in a project where outdoor air requirements in corridors are met by means of induced ventilation (exhaust fans in contiguous WC's induce make-up air in the corridors).

when I have an addition project do I have to demonstrate compliance for the new addition and renovated areas or does it have to be applied to all areas? (existing to remain, renovated and new)

Hello, Is it okay to install one airflow measurment device within an outdoor air intake that serves multiple AHUs or does each AHU need to have its own airflow measurement device? Thanks!

I understand that for densely occupied spaces an alarm (visible or audible) is required.

the designer suggests to use VOC sensors instead of CO2 sensors in a number of lunch rooms and the smoking room.

Can natural ventilated stairs and lift shaft excluded from requirements of this credit? If not, how can these spaces comply with this credit?

Could a presure deferential sensor used as outdoor air monitoring devise?.

Dear all, We are working with a project that have a densely occupied meeting room.
