Q: I'm a graduate student at Texas A&M University.
I'm wondering if there is any acceptable calibration tolerance in recent IPMVP publications (for example, MBE & CV-RMSE values on a monthly & hourly basis).
I think the ASHRAE G14-2014 & 2015 FEMP provided these criteria, but I should be back to the 2002 IPMVP to get this criteria.
A: HI, you are correct. Recommend continuing to refer to ASHRAE, FEMP and other Industry publications regarding acceptable calibration tolerance guidance for different applications.
