Hello all,

I am following the Equest-users Digests for a while and learn allot. Thanks
to every one of you for all your helpful comments and guides.

Now I am working on the energy model of an existing warehouse to be
renovated as an office building. For baseline model, there are five packaged
rooftop VAV systems with Hot-water fossil fuel boiler (System 5 per ASHRAE
90.1). However, for the Design case five rooftop systems with fossil fuel
furnace has been defined.

I am in Detailed Date Edit and when I change the system heat sources from
Hot Water Loop to Furnace, I get an error (Terminated Due to Errors).
Actually, if I leave just one system heat source as HWL it would be OK and I
don?t face any errors, but when all heat sources have been changed to
furnace and there is no Hot water Loop assigned to any system, there will
errors.

Please find the attached pd2 and inp files of the project.

Your comments would be greatly appreciated.
