[Equest-users] Cooling EIR and unit EER

I believe the number for EIR you are calcilating removes the fan energy, a requirement of ASHRAE-90.1

I think.

Hello 

I've attached the document. Though it is nothing more than a sheet out of our assignment for the eQuest class.
I do not have the original document from where this would have been taken. Hopefully this helps :)

Regards
Supriya
