We've worked with envelope commissioning agents. They can be very helpful or less so depending on their knowledge. When you are working with an expert, it's worth it. It's good to have another set of eyes on the documents, particularly if the exterior envelope is not typical. ASHRAE requirements can make the coordination of the exterior envelope and HVAC system critical.
If you are to work with one, make sure they are familiar with construction techniques and climatic conditions in your area. Involve them early in the design process, even during Schematic Design.
The commissioning process can add work to the Architect. There will be additional meetings for design review at each phase. If there is on-site testing during construction, the Architect might be present, but that is not a requirement. Submittals by the contractor should also be routed to the commissioning agent for their review.

I wonder who has had to deal with an envelope commissioning expert, and how that interaction worked in terms of duplication of effort and areas of contractual responsibility; seems to me there is plenty of room for conflict and confusion- and added work for the architect of record.
