Need guidance, not sure whether we have to register as 1 project or 2 here. We have a project whereby the tenancy space involves 1 building of 8 floors and the adjacent building of 3 floors. It has been suggested that we should register the two buildings as two separate LEED-CI projects due to definition of MPR. But I would though it matters not how many buildings the CI project lies, it is still a CI project nevertheless, here it is not exactly a campus.
It is a bit of a grey area, but the relevant sections of the new MPR guidance from June 2011 appears to be page 18 and the top of page 21.
It looks like it may be possible to register it as one CI project if you meet the conditions a thru f: (unreasonable to draw boundary at party walls, it is a single construction contract, you are certifying all of the work, clear boundaries and signage, etc) To meet condition F - not create an difficult review process - you would probably need to show that you are doing identical or very similar work in the spaces that are in different buildings. In general, if it is treated as one project, the information you fill out for a credit form needs to be true for the spaces in both buildings. If the two buildings have very different energy use, different ventilation systems, different lighting power densities, etc, it going to be hard to document it as a single project.
If the buildings or improvements being done are significantly different, you probably will need to treat it as a campus, or at least use the "Block" function so that you get the same reviewer for both projects and can cross-reference shared project information.
