FAQs about IEQp1 :

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

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?

EBOM-2009 IEQp1:Minimum IAQ Performance

10% exemption?

I'm unclear if 10% of space can be exempted for this prerequisite. Could someone clarify this? We have a project where we have several retail spaces on the ground floor of an office high rise. We are currently reviewing retail leases to understand if the owner has authority to measure fresh air to the spaces. The office portion of the building has a central plant and supply, so it is under central control. What can we expect will be the position of our reviewer regarding retail spaces?

Yes, per page xxiii of the LEED-EBOM Reference Guide, all prereqs and credits except IEQp2 are subject to the 10% exemption option.
