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

Total Peak occupancy filled in Plf 3 AND the one used in IEQ P1

I am working on a LEED EB project, the Total Peak occupancy filled in Plf 3 is clear, however, but just wonder how this number can also maintain reasonable in IEQ P1 in order to calculate the Population Diversity (D) ? Since the Total Peak Occupancy for IEQ P1 might has to include the seatcount in conference room. Please advice, thanks

I don't see figures like those you are referring to being requested on the IEQp1 forum Please correct me if I'm wrong, or missing something.

I would make sure that the aggregate system level occupancy, after accounting for diversity, is close to the Total Peak occupancy included on PIf3. If you are using the 62MZ calculator that value can be adjusted manually after the potentially critical zones are input. One other thought is that seat count is not necessarily the appropriate value for occupancy to input for the potentially critical zones. Instead, the EBOM calculation requires us to input the number of occupants based on the max occupancy observed during normal operations for the space.
