Being that my project is a convention center, it does not qualify for energy star. Therefore, I am using the EAp2 Case 2 offline calculator in conjunction with the EPA portfolio manager tool online. Option 2B Historic Data appears to apply to us since we have already compared our facility with 5 other convention centers. The result of that comparison were not helpful since they were all approx. 300 EUI less, due to all being previously LEED certified. My question is: how do I go about fulfilling option 2B? Upon inputting the EUI for the last four years, the offline spreadsheet continues to say N/A for the "Approximate percentile above National Average."
