Hello, I’m working on a Core & Shell office building in Bogota and the baseline system is 8. The building has a central cooling system with chillers and air handle units in each floor, it doesn’t have a heating system. According to the G3.1.10 (c) table of ASHRAE 90.1, the proposed model must have a heating system equal to the baseline, ie electrical resistance and parallel fan-powered boxes (PFP). I don’t want to model PFP boxes in the proposed model due to the fan power consumption. I don’t want neither to model a lower heating temperature setpoint because the fan in the PFP box would be working all the time. To meet the baseline heating system, Can I use only an electric resistance in the air handle unit or placing a simple reheater in the zone enough? Or is necessary to model PFP boxes with a heating coil in each zone? Thank you.
