1. Lower the Space temperature to 68F.=20
2. Using the FPH system in eQUEST. This doesn't allow for cooling
however, and uses no fans (we still have air supply in our building).=20

3. Andrew Craig suggested inputting the capacity of the radiant system
as an internal energy source. (This is great because it allows the fans
to cycle on/off and maintains the cooling side. It doesn't calculate
heating loads on the radiant slab though)

What I plan to do is use the FPH system and setback the thermostat to
68F in these spaces. This will allow me to calculate the heating energy
on the radiant coil. I then plan to use Andrew's "internal energy
source" method to calculate the airside system loads, and add the FPH
heat load to that.=20

Does this seem like a reasonable method to model this?=20
