<DIV>The I/O Reference can be helpful, but sometimes it's even more helpful to look at the example files (in a folder called "Example Files" that comes w/the EP installation). You could write the EnergyPlus Yahoo! group, also. It sounds like you've already looked at the .expidf file, right? If you haven't, that's the file that contains the objects created by the Compact HVAC object, in all their expanded, noded, looped, branched glory. It's created automatically when you simulate your .idf file. I couldn't tell from your email if the problem you were having with Compact HVAC was related to Design Builder or not. Good luck!</DIV>
