I am working on simulation with Carrier's HAP. I have to model baseline system 8 (VAV with PFB boxes) in accordance to ASHRAE 90.1 Appendix G 2007. As heating type I should use Electrical resistance. I would know if electrical resistance means electrical coils on field or hot water with electrical boiler.
I have this doubt because I'm not able to model the 25% oversizing for heating, when I use the elctrical resistance on field (ref. G.3.1.2.2).
Could you help me?

Thank you.
