[bldg-sim] Equest - Process Loads: Heat Gain or Consumption

When I am performing calculations in Equest I am confused about several
screens:

 

1)     Lighting: I am asked to input the W/ft^2.   Does this only
account for the amount of electricity consumed to provide light to the
space and/or does it also account for the heat the light gives off?

 

2)     Miscellaneous Equipment: If I have a coffee machine or computer,
does this ask for the energy consumption only and/or the heat
contributed to the space?

 

3)  Process Loads: on the screen there are two columns under Electric
and two columns under Process Loads.  I want to make sure that the heat
gain from my pumps, chillers, etc is reflected in these spaces. If I
type in the btu/sf under process loads will that do the trick?  Does the
electric side need to know the total electric consumption in w/ft^2 for
these pieces of equipment or can I leave it blank? My big issue is
accounting for the heat gain from the equipment and what each of the
four columns represents: energy consumption or heat output.

 

As always, Thank You for your help.
