My question is currently about the scope of certification, but has it main impact on the building's energy performance.
We are currently working on a major renovation and extension of an office building in France. A problem has been raised regarding the inclusion of a ground floor retail space within the LEED project scope. The retail space extends primarily outside the building’s footprint, but a certain part (30 to 40%) is included in the ground floor of the renovated building. The owner of the retail space is the same as the office building. The commercial space has technical facilities completely independent of the renovated building and managed by the tenant. The facilities are located in the basement that has a shared use of parking for the offices and the retail space.
The proposed renovation and extension does not apply to retail space which will remain in operation during construction. Can we therefore exclude this area of the LEED project, and therefore the energy model?
If we had to consider the retail space, what would be the involvement regarding LEED credits, in particular EAp2/EAc1 and IEQp1/IEQc2? Must we take into account all their technical and MEP systems and include this space in the energy model?

Since you probably need to include this space to qualify for LEED under the MPRs you will need to include them in the energy models. This is a pretty unusual situation. Believe it or not the easier and clearer path would be to document this retail space for all the applicable credits and include it in the certification. Excluding this space is more difficult to explain and justify.
The energy models should be the same for this space and the ventilation should be calculated based on the current systems.
