commissioning of outbildings

It is not mandatory to certify every building in your campus. Therefore I think it is also NOT mandatory to do perform commissioning activities in the non-certifying buildings.

Jutta, it all depends on what you mean by "building services." If there is a boiler plant (for example) in another building that is feeding yours, that is fine. However, this then becomes a DES system. The energy model will need to follow the guide for DES, as will the commissioning. In this case, the commissioning would apply only to the equipment feeding the building being certified. The guide says that the system must have been commissioned in the last 2 years (I think). If you can tell me what services are in the adjacent buildings, I can give better guidance.

I am not as familiar with using the campus registration, so we may need someone else to chime in, but my understanding was that you work on campus wide credits, then you use them on individual projects for certification. Each project has a specified boundary and the boundaries are to join in a logical way. However, if you are just doing NC for a single building on the campus, and not doing the campus certification process (confusing I know), you evaluate the scope based on the boundary. So, I doubt if the guard house would have to be commissioned. Same with the warehouse. The utility plan BUILDING would not have to be commissioned, but if the plant develops hot water, steam, or chilled water for your building project, then those systems would need to have been commissioned per the DES guidelines. You also use the word "process", which can mean something used only for a manufacturing use, that would not be part of a LEED commissioning scope. Because language can mean a lot, I may not fully understand your situation. Remember that you can always ask for a conference call with GBCI for a more in depth discussion.
