I'm working on a existing office building that is intended to pursue LEED EB:OM certification. Based on preliminary assumptions I'm afraid it wouldn't be able to achieve the 69 score necessary to comply with the prerequisite.
If my resulting score is below 69, what should I do to certify this building?. Should I implement energy efficiency measures and wait a year to justify those measures with energy bills? or Should I implement the measures and justify the energy efficiency with path 2?
What is the correct path to follow in this scenario?
Thanks!.

You don't need to wait a year to see the impact of the energy efficiency measures you implement - your Portfolio Manager score should start to rise as your efficiency improves. To get the full impact you would need to wait a year - how long it will take to get to 69 depends on where you are now and how much of an impact you can make. That said, I would look at path 2 as well to see which produced results faster (and more points for EAc1).

Michael is absolutely right about the score rising over time as efficiency improves, and that process may take less than a year (to surpass 69). However, Cases 1 and 2 shouldn't be viewed as 'options' from which you can select the more favorable route - if your building is indeed an office building, and therefore rateable in Energy Star, you are required to use Case 1. Case 2 is only for non-rateable building types and can't be substituted.
Hope that clarifies things a bit.
