Hi everybody;

I'm working in a CS office building with a designed ceiling plenum natural ventilation system for tenant spaces. The owner of the project will be providing the louvered inlets and outlets needed for the system to work, but there has been some discussion regarding the installation of the ceiling in tenant spaces by the tenants or the owner.

The question is, if the owner doesn't provide the ceilings for the tenant spaces, but provide the rest of the system features and explains the tenants how to install the ceiling in order for the natural ventilation system to work will that be enough for compliance? Or a legally binding lease agreement would be needed in this case?

Thanks for the help
