FAQs about IEQp1 :

What if after our Preliminary Review we have to re-work the ventilation rate procedure calculations and find that we need to make corrections to the system in order to meet the prerequisite? Can we redo the outside air testing after making corrections? Wo

What if our systems do not meet the required outside air when systems are tested at worst-case conditions?

Our building has a single fan that supplies outside air to multiple AHU’s. Do we need to perform outside air testing at the supply fan or at all AHUs?

We have a VAV system where single AHUs serve multiple zones. Do we need to take outside air measurements at each VAV box?

EBOM-2009 IEQp1:Minimum IAQ Performance

Exhaust System test for pressurized buildings with no exhaust

Hi all, We have an existing building built in the early 1900s with three 100% make up air units supplying fresh air with no exhaust. The building is pressurized and fresh air exits through the building envelope. We have taken supply air measurements. What are the EQp1 guidelines for exhaust system tests on pressurized buildings without exhaust fans? There are four small evacuation fans for each bathroom which evacuate less than 5% of the total supply air. Thank you for your help with this question.

It sounds to me like you would test for proper functioning of the evacuation fans and then include a narrative with the prerequisite submittal summarizing the building's strategy related to pressurization and exhaust.
