I am working on a large campus project. We are planning on obtaining EA 5 for all eight facilities on the campus. However, we are not doing energy models for all eight facilities. We are obtaining credit EA 1 for five of the buildings using the Prescriptive Compliance Path: Option 2 and the Prescriptive Compliance Path: Option 3. SInce we don't have an initial energy model to 're-calibrate' for these five facilities I would like to know if we still obtain this credit? Would the authority responsible for validating the M&V process after occupancy be responsible for creating a model? Does our M&V plan need to indicate this?

You could still get the credit by following Option D and creating an energy model. This would have to be clearly spelled out in the M&V Plan and part of the plan is always to identify the responsible parties for all of the M&V tasks.
Unless you can make the case that this approach adds value to the projects, it strikes me that attempting to do so is simply a point hunting exercise. I would concentrate on the value proposition and only follow Option 1 if it makes sense to do so. Otherwise consider Option 3.

Marcus, Option B for ECM isolation might also be technically possible...although it may be difficult depending on the mix of ECMs, and whether any interact. (And what doesn't interact with the HVAC system?)
I don't think Option D is point hunting necessarily if the client really wants to verify the performance. It would be an example of unfortunate timing, since the energy models could have been used for so much more if completed earlier instead of post-construction.
Option 3 for one point is going to look very attractive to your client if the cost of full M&V (and all of this modeling) is too high.

I have not seen a green building yet where Option B would work but I am sure it is possible.
Sounds like we agree that any IPMVP M&V effort is only worth it if it adds value. IMO it is point hunting if it does not add value beyond the accumulation of those points. If it does add value then it is all good.
