This standard defines the calculation method for the fan energy index (FEI), which is an energy efficiency metric for fans inclusive of motors and drives. This metric provides a standardized and consistent basis to compare fan energy performance across fan types and sizes at a given fan duty point.

Type of Comment: General

Comment (justification):
The FEI value for 0 pressure and 7500 cfm (1.67) is wrong. Comment from Nazme Mohsina, error found by Ms. Tan Tin tin.

Proposed Change:
Correct this entry and any others that are not correct.

I suspect there are small rounding errors in this table; (-0.5%) to (+0.9%).

FEi values of that example are way off.
