<DIV><SPAN class=709113815-24052011><FONT size=2 face=Arial>Is there a general
consensus on the best interface for creating and editing mechanical systems
within EnergyPlus? We are looking to take DOE Commercial Building
Benchmark models (in .idf format) and run simulations with different HVAC
systems (ducted return, un-ducted return, radiant panels, etc.).
What EnergyPlus interfaces have you had success using to do things
like this?</FONT></SPAN></DIV>
