Given our unique project conditions we are pursuing this credit via Case 2, Option 2B. This option allows for normalization of historical energy data for things such as, changes to occupancy, operating schedules, space use.

How do we derive the multipliers that should be used for normalizing our data? One reviewer we spoke to indicated that an energy model was not needed and the calculations could be done much more simplistically. Can we use linear relationships such as twice the number of occupants equates to an assumed 2x energy usage? Or, there was an addition to the building, so would a 20% increase in conditioned space volume equate to an assumed 20% increase in energy usage? And what about less quantifiable aspects like space type changes?

Does anyone have experience with this? Any tips or resources for this endeavor is greatly appreciated! We are trying to get this turned around quickly.
