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

EBOM IEQp1-A1 Statement "Would need over 100% OA Intake"

Our EBOM 2009 project credit data has to be completed by 8-5 and I am getting a message "Would need over 100% OA Intake" at the end of the IEQp1-A1 VAV data input form. All values look good with the measured OA intake to the AHU exceeding the required minimum amount. What does the over 100% OA statement mean? We are using the V4 form.

Look for the zone in purple italics in the calculator. Is it getting enough ventilation? Your "critical zone" may be under ventilated. Also, which cell is this message showing up in? If it's showing up in row 43 of the USGBC version of the ASHRAE calculator, it may mean that you meet the prerequisite minimum OA, but not the 30% increased OA for IEQc2.

Ilona, I am referring to the LEEDonline "VRP Compliance Calculator" found in Appendix 1 of the V4 data entry form. We are not using the ASHRAE calculator "62MZCalc". The critical zone had a Zp of 0.99 so I changed some values an now the highest Zp is 0.93. The note is removed when I hit recalculate but comes back when I reload the saved form!! :-(

Hi James! I have the same issue filling out the IEQp1 form. How did you solve it?

I contacted the GBCI and they replied that I should use the "special circumstances" section to notify the reviewers about this glitch in the form. I hope this will help other project teams!
