Does anyone have any recent experience being awarded an ID point for using machine roomless elevators - submitting documentation from the manufacturer regarding process load/energy performance savings?

Pamela, any energy efficiency from the elevator would be captured in EAp2/EAc1, so there would not be a rationale for an ID credit.

I fully concur with the logic of your statement. Perhaps LEED needs to reach out to the elevator companies to advise them against false representation... Kone, Otis, Schindler all have statements on their websites suggesting an ID credit is possible for selecting MRL elevators (see Kone http://www.kone.us/sustainability/leed/). There are even continuing education articles published by Architectural Record suggesting MRL's are eligible for an ID credit (Next Generation Machine-Roomless Elevators - published May 2012 (http://continuingeducation.construction.com/article.php?L=294&C=891&P=6).

You can achieve the ID credit but not for energy savings as noted by Tristan. You can however pursue the ID credit by pursuing the other environmental benefits such as no hydraulic fluid and savings on materials by having no machine room or elevator pit etc. Kone has been the only elevator vendor that has been able to provide the required documentation thus far.
Thank you,

Donald, have you seen this successfully done? I typically advise project teams away from ID approaches that rely on a single technology.

Yes, with the noted vendor. I understand your point on a single source and I agree, but I felt they needed to know what they are getting themselves into. We just haven't been able to get the required documentation from other vendors. We are actually in the midst of trying it with a different vendor now and will see what happens because we received some documentation but not all that we asked for; we had asked for the same information we received from the successful vendor. We are therefore going to provide a narrative culling information from various sources to hopefully fill in the gaps. If there were other options for this project I wouldn't pursue this ID credit.
Thank you,

Many thanks for all the commentary and feedback on the MRL / ID topic. We do have Kone MRL's on the project and are coordinating with their rep. One last question, to clarify whether you would submit as a design or construction ID credit, or if it matters. We're getting ready to submit LEED final design review credits, so I would prefer to have an opportunity to respond to comments by submitting it as a construction credit.
