We are working on a residential building where split AC units are provided in every room for each unit with no mechanical ventilation. The ventilation strategy is relying on natural ventilation through operable windows.
Regarding the natural ventilation monitoring requirements in LEED v4, none of the options seem feasible in our case, since exhaust fans are only installed for toilets and kitchen hood.
Does anyone have experience with similar projects that can share what is the best strategy for ventilation monitoring in naturally ventilated residential buildings?

Since you are required to mechanically ventilate a mechanically cooled space, you will need to show mechanical ventilation. To do this using exhaust, you will need to demonstrate that the exhaust fan draws air across the occupiable spaces. You will need to choose the correct effectiveness factor for your layout.
