We are working on a natural ventilated CS office building. The Leedonline form asks to fill in a table with the operable window area, in order to calculate ratio of window to occupiable area.
This building's natural ventilation system consist in ceiling duct system with openings to the outside thus creating a windflow that ventilates the offices. This offices have operable openings to regulate the inflow of air. Do you thinks we should include these operable openings' areas in the window area of the table?
Thanks for your help

instead of a window area, you probably need to use the area of the openings on the outside of the building, since this is the "inlet" area that is delivering the outside air. That open area needs to be at least 4% of the floor area it serves.
