LEED EB - VERSION 2.0 WE prereq 1

There are some pretty significant differences between the way that compliance was calculated in EB v2.0 and the current methodology for EBOM v2009. I'm not quite sure that I understand why you want to use an EBOM credit form to document your NC project - have you tried using the WEp1 Credit Form provided in your LEED-NC scorecard in LEED Online? I'd strongly recommend this approach since LEED-NC uses yet another methodology that is different from both EB v2.0 and EBOM v2009. Specifically, the NC version of the credit calculates the baseline water consumption in a much more stringent way and you'll need to make sure you meet the NC requirements for your project rather than the more relaxed EBOM requirements.
