Certifying 2 separate interior spaces in 2 separate buildings as 1 Certification

I have 1 CI project which is taking place in 2 adjacent buildings (Europe). The client is responsible for both interior spaces in each building, but the client also wishes to treat as 1 LEED Assessment. Is this possible?

Also, how would this be best documented for issues such as energy modelling and IAQ, as the interior spaces could well both be served with two different mechanical/ventilation systems, as well as different envelope, building physics etc attributes.

Thanks

I don't think it's possible to pursue one CI certification for spaces spread across two significantly different buildings. As you described, the different envelope, mechanical systems, etc., in the two buildings makes it very difficult to document the energy performance and ventilation with one application. I've only seen a singe CI certification applied to spaces in two different buildings when both buildings were essentially identical (age, design, envelope, mechanical systems, etc.) and the tenant improvements were done for the entire space of both buildings, including new HVAC equipment that was essentially the same for both buildings. You can look into the "block" registration which provides more consistency in how the two projects get reviewed. Search for "How do I register a block" on the USGBC web site for more info.
