I am documenting an energy model for LEED 2009 EAp2/EAc1 and I would like to include a document that describes the modeling techniques used for each modeled system. The reason that we would like to include this document is that the software that we used (HAP) was unable to directly model one of our systems (rooftop WLHP tied to VAV boxes) so we had to use a work-around to accurately model the system inside of the software. Because of how we chose to model this system, we were able to get accurate final results out of the the software without doing any exceptional calculations outside of the software.

Should this write-up be uploaded as an exceptional calculation with zeros entered in to the form for the exceptional calculation energy savings? Or is there another way to bring this document to the reviewer's attention?

Thanks!
