RE: [EnergyPlus_Support] eQUEST vs EnergyPlus: Fan Energy Consumption




Your data indicates that there are probably several discrepancies because the pattern varies.

·         Are you aware that E+ ?fan efficiency? is actually (fan mechanical efficiency x motor efficiency)? (I don?t know how eQuest calculates?)

·         Clearly the eQuest fan is running non-stop, while the E+ fan is not.  There?s a schedule affecting them which is different?

o   E+ will not cycle its fan during unoccupied periods unless you use a AvailabilityManager:NightCycle

o   E+ cycles at night with a specific delta T variation from setpoint and for a minimum time period. These are specified in the AvailabilityManager mentioned above.
