ASHRAE Appendix G - Compliance Form ?'s

Hello! I've been completing the ASHRAE appendix G 90.1 Compliance Form to go along with my energy model, but I have some questions that I have not been able to answer with searching and experimenting. 

1. The compliance form has a page to paste the parms file lines - I noticed that a parms file is not generated once in detailed data edit mode, so do I need to stick to the wizard mode for this?

2. In the "Energy Performance Summary" tab, some of the model values are off (~400-600%) form the PNNL prototype models it is compared to. I've been able to troubleshoot most things, save for Pumps and Service Water Heating

-The pumps are off in both baseline and proposed (system 3). Where would I begin to troubleshoot this significant of a discrepancy?

-The service water heating is 4x the prototype model, the only way I've found to solve this is to halve occupancy and usage. I have it set at 0.5 gal/person/day (for a medium office), however most sources online that I can find reference 10 gal/person/day. Do you have any suggestions to better adjust these values?

Thank you, 

Kelly
