Dear Group,

Does 90.1 Minimum Efficiency Requirements include fan energy?, I am referring to table 6.8.A which specifies for air conditioners less that 8.8 kW capacity a minimum COP of 3.52.
Since my building does now have a cooling system I have to use the baseline system (PTAC) and I am not sure if I have to model fans explicitly.

Kind Regards,
