EBOM-2009 EAp2: Minimum Energy Efficiency Performance
Is there any real disadvantage to moving a project to LEED EBOM 2009 from the 2008 version? This project is in a urban setting and no real documentation has been done.

The pros/cons of moving from EBOM to EBOM 2009 tend to be project specific and related to your goals in terms of points. Very generally, you'll find fewer points (relative to the minimums required for various certification levels) relating to purchasing, waste, and cleaning in EBOM 2009 than EBOM; in contrast, the 2009 rating system has 15 points associated with alternative transportation that may benefit a project in an urban setting. I would definitely recommend a close reading of the EBOM 2009 prerequisites; for the most part they are the same as in EBOM but some subtle distinctions exist. Overall, I suspect you'll find few disadvantages to making the switch.

I second the notion that you should do a side-by-side project specific comparison. The points reweighting in v2009 more handsomely rewards alternative transportation, water efficiency, and energy efficiency, so if you're doing great in those areas it may be a benefit to transition to 2009.
On the other hand, if there's no real difference in the point situation and you're familiar and comfortable with the 2008 requirements and submital process, it may better to stick with 2008. The LEED Online v3 platform will take some time to get familiar with, and as will any new launch, still has various glitches being worked out.
