Open Parking Garages

[JVL]

I have a garage where the North and East sides will need to be relatively enclosed, but the south and west sides can be relatively open. Could this ever be compliant with IBC 406.3? Technically there would be uniformly distributed openings on two sides... but i'm fairly certain that garage won't feel "naturally ventilated"!

Are they 40% of total open on S&W?

OPEN PARKING GARAGE. A structure or portion of a structure with the openings as described in Section 406.5.2 on two or more sides......

406.5.2 Openings.

For natural ventilation purposes, the exterior side of the structure shall have uniformly distributed openings on two or more sides. The area of such openings in exterior walls on a tier shall be not less than 20 percent of the total perimeter wall area of each tier. The aggregate length of the openings considered to be providing natural ventilation shall be not less than 40 percent of the perimeter of the tier. Interior walls shall be not less than 20 percent open with uniformly distributed openings.

Exception: Openings are not required to be distributed over 40 percent of the building perimeter where the required openings are uniformly distributed over two opposing sides of the building.
