Hi,
We are working in a Core & Shell project where the project owner has decided to provide only Chillers n Pumps to the tenant. Whereas AHU, Fresh air fans will be part of tenant scope of work.
In this scenario since the project scope of work includes partial Mechanical system, is the project owner still mandated to provide mechanical ventialtion as part of his scope or can the mechanical ventilation be part of the tenant lease agreement to meet Minimum Indoor air quality.
Thanks

I have never been in this exact circumstance. However, the reference guide states that "If the scope of the core-and-shell project includes mechanical systems, the project team must comply with both the ventilation and monitoring requirements." You may be able to argue that the ventilation portion of the mechanical system is not being provided. However, I would expect the reviewer to require to at least see that a hypothetical ventilation strategy could be employed. I would expect this for a couple of reasons. First, the chiller and pumps would need to be designed for the anticipated ventilation load or it could be grossly over or undersized. Second, most core-and-shell buildings have central areas that are not part of the tenant scope of work (lobbies, corridors, etc.). These areas would need to be ventilated to comply with ASHRAE 62.1.
Hope this helps.
