Yes, 90.1-2007 is an acceptable baseline. In order to produce a calibrated baseline model you will first have to calibrate the proposed model. So you must calibrate the proposed model with the actual utility bills in order to determine if you have achieved an acceptable level of calibration.

Marcus, Thanks for your reply. I presume that if the results from the calibrated proposed model differ from the annual energy costs (deduced from bills) by over 10%, we will need to develop an corrective action plan, am I right ? Thanks,

Your M&V Plan should contain a general corrective action plan in the event that the savings are not verified. The Plan would also spell out the acceptable accuracy of the calibration. Once calibrated within the acceptable accuracy the actual savings are then determined by comparing the calibrated model to a calibrated baseline model. If the actual savings differ from the predicted savings by a significant amount then the corrective action plan kicks in.
