One, this document is optional for LEED, not required, according to the Beta version of the EAp2 online template that I last used. Two, while I can only guess the intent of the form, the design day section of the form appears to be for reference only (containing other general information such as name, address). I do not see any wording in ASHRAE Standard 90.1-2007 that requires 1%/1%/99.6% temps to be used for mechanical design. Three, this document is for the proposed design.
