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?

For EBOM IEQp1 we have a school using a dedicated ventilation AHU providing ventilation air to classroom FCU's. Will we meet the prerequisite by using a TAB contractor to measure the OA flow at the dedicated ventilation AHU which is ducted to about 40 FCU’s?

Yes, you can manually measure AHUs as stated above. We have used this method on LEED EBOM projects. Is the DOAS constant volume? For variable volume systems you often have to use the minimum air flow setting.
