I had a comment on a LEED review in IEQc7.1 to provide a summary table which lists the heating and cooling design parameters used for each space type and the Room Input Reports for each space type. My question is, what is a Room Input Report and what should it look like?

Interesting, I have not seen that asked for yet on projects I have worked on. Basically, this credit requires you to design to meet the comfort conditions of various space types, and to give what those parameters should be. A Room Input Report would come from the energy model, showing all the information used for each space in the model...including the set points used in the simulation. So they are basically asking you to prove that you used the set points that you claim for this credit in the energy model. Make sense really.
Does raise the question (and I would like Marcus to chime in if he monitors this thread), could you make a case (or are you allowed) to have different set points between the baseline and the design models? I always thought that the set points had to be the same, but if you made changes in your design to provide comfort in a wider range of temperatures, could you claim that in the performance?

It sounds like perhaps the compliance option selected was load calculations and what the reviewer needs to see is that the appropriate occupancy levels and occupant loads (sensible and latent heat gains) were used for sizing the equipment. As for what report should be submitted, it depends on the software used, but typically this information can be found in the room input summary reports (as noted in the comment).
As for the question for Marcus, he is busy (and limits his efforts to the EA credits) so the quick answer is that you are correct - the space temperature settings in the energy models must be the same in the Baseline and Proposed case. Any savings associated with a wider comfort range would need to be submitted as an exceptional calculation.
