I've worked mostly in Trane's Trace, but am starting to do more work in
eQUEST. At this point I do not know of an easy way to compare different
systems in eQUEST, say packaged single zone DX cooling with gas-fired
furnace versus a ground source heat pump. In Trace you basically create
a new building with each alternative where you can easily change
everything within the alternative. At this point the only two methods I
know of to compare different systems in eQUEST is to create global
parameters for a parametric run, but with all of the system definitions
unique to each system this seems like a dubious task to change an entire
system. The second way I know of is to 'save-as' in another file and
just switch out the system. Does anyone know of a better way to run a
comparative analysis of different systems in eQUEST?

Thank you,
Dan Croisant
