We are modelling a typical office building with multiple shells in e-Quest.

1. The fan demand in the "Performance output tab" which is obtained from "PS-E Energy End use summary " is less compared to the Fan design input in " Air side HVAC tab which is obtained through " SV-A System Design Parameters" report.
This henceforth creates a flag in the final performance outputs tab which reads "The fan demand ( as reported from performance outputs tab) for the baseline and or proposed exceeds the fan power as reported from " Air side HVAC tab".

Please advise on where we could be going wrong with the inputs that we are seeing this difference in both proposed and baseline models. Fan curves are as per ASHRAE 90.1 using method 2 of table G3.1.3.15
