Control monitoring in tenant spaces

I can't be certain, but the way I read the credit, you would need to provide either a direct exhaust airflow measurement device, an alarm that indicates when the windows are closed, or a CO2 sensor in all the anticipated thermal zones. I don't see an exception that allows for less. In fact, the note regarding Core and Shell indicates that a mechanical ventilation system must be capable of ventilating the entire space based on anticipated occupancy. That to me would indicate that the intent is to provide capability for ventilation (or in this case a way to show compliance with natural ventilation). It is possible that you could argue that the shell is providing the capability to comply with the requirements (ie. a system that would monitor the window positions) but write into the lease that they need to provide the actual sensors. I think at a minimum the shell would need to provide the backbone. (The justification would be that the Shell provides the mechanical ventilation equipment, but the tenant improvement installs the ductwork etc.) I hope this helps.
