Dear all,

I am trying to do T-24 2008 compliance through equest and I keep
receiving these error messages (screenshot attached). Can anyone point
me out to any documentation regarding these errors?

Thanks

Jude.

P.S. Nick/Aaron/Ramya/Carol/Chetan, your suggestions for simplifying the
model really worked well. Its running smoothly now except for the T-24
compliance stuff. Hopefully I will get a right direction on that as
well.

Thank you so much J

I've been struggling to use equest to do T24 also. I posted a question about how to model 100% OA systems and got no response.
I've seen the errors you're having before. On your fan wizard screen you need to set all the values for the static pressure and cfm so that the program can select a proper fan curve. Also the division by zero warnings suggest you have fields that need numbers to be entered. If that still doesn't work, you may need to go into detailed edit mode to find the proper input fields.

Does anyone know how to model both the proposed and base line cases as having 100% OA? Equest is only calculating that my building needs 4K cfm of OA for the baseline, but this is a research lab and really needs 20k cfm of OA. My T24 compliance check shows a huge load difference between the proposed and baseline models so my building is noncompliant.
