Does anyone know why I cannot model a VAV AHU with a steam loop/boiler
for space heat?

It is a central AHU with zone boxes, therefore I am modeling (1)
Air-Side HVAC System.

When reviewing the output consumption using this configuration I do not
see any energy consumption for space heat, but when I switch to a
furnace instead of the steam I am able to produce logical /practical
consumption numbers. What am I doing wrong?

Thank you in advance.
