amined to ensure they reasonably matched the typical range of
indoor conditions during occupied and unoccupied days.5 This baseyear model with “normal” weather was archived, with
both printed and electronic copy of input data, diagnostic reports
and output data.
6 The difference between the two versions of the baseyear model
were computed as the Adjustment term, and is shown below.

From Equation 1, the energy savings at the standard set of condi-
tions are:

Baseyear – Post + Adjustment = Savings
