<div>Hello,</div>
<div> </div>
<div>I have an issue with modeling a Baseline PTAC unit. When I consult the fan curve in appendix G of ASHRAE 90.1, the fan power for my PTAC system is very high. I add up all of my PTAC unit's cfm and then apply them to the curve but I am getting a result
around 0.000656 kw/cfm. This also lowers the cooling EIR by a large amount when the overall efficiency is taken into account. This is a very large amount of energy over one year's time. I need to simulate the fan power because the heat source is hot water
and it will not be accurate if there is no fan power during the winter.</div>
<div> </div>
<div>Also, The proposed system is heating the rooms by radiant floor heating. I use baseboard heating in the model to simulate this, but do I also use baseboard in the baseline design or just hot water coils in the PTAC? Thank you for any help.</div>
