Is the next step just to calculate the bhp for each unit per table G3.1.2.9, then calculate fan power from section G3.1.2.9? <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I did this for my first unit and got a value of .000768318 KW/CFM. This was for system S1 with a baseline “design” (from the air side summary report) CFM of 1,986 CFM. Does that seem like a reasonable #?
