NC-2009 IEQp1:Minimum IAQ Performance

IEQ Prerequisite 1 Form - reoccuring error

IEQ Prerequisite 1 Form: I have a reoccurring error on my mechanical ventilation – Multiple Zone Chart that is reading “Would need over 100% OA Intake”. However, when you click on the calculate button this error disappears, showing that everything on the form is complete/compliant. The problem is when you leave the form and come back on the page at a later time the error reappears. The overall form always shows up as compliant even when the error is on the page. Has anyone had this error occur to them and do they know of possible solutions to make the error flag go away. (The system in use is an 100% OA ERV Unit with VRF’s used to condition the spaces.)

Ken, I have not encountered this error before. Which version of the IEQp1 form are you using? In my experience errors in the prerequisite form will not stop you from submitting your project, even if you are shown as not meeting the prerequisite. As long as the correct information is in the form, the reviewers will be able to award your team the prerequisite. You can even select the alternate compliance path option and specifically mention the error in the form if you like. That said, because of problems like this, I recommend using the spreadsheet 62MZ calculators available through the "Credit Resources" link on the Credit Information page for this prerequisite on LEED Online.
