<DIV>Maria, Rohini, and anyone else in the know,</DIV>
<DIV>You brought up an interesting point with ASHRAE 14. It suggests MBE and CVRMSE numbers, which seem pretty difficult to achieve. Are many practitioners hitting these numbers in the field? If so, what is the end purpose of these calibrated models? It seems like the IPMVP 2006 (referenced by the LEED M&V credit) *suggests* using ASHRAE 14; however, their own case studies do not seem to hit these ASHRAE targets, which makes me curious.</DIV>
<DIV> </DIV>
<DIV>For those of you using models for commissioning what level of calibration seems appropriate, being realistic about effort and model usefulness? Is anyone in practice using calibrated models for on-going commissioning/fault detection?</DIV>
<DIV> </DIV>
<DIV>Thank you for any information!!!</DIV>
