A storage room with openings on a direct naturally ventilated space must meet the requirements of ASHRAE 62.1 for spaces without direct openings to the outdoors ventilated through adjoining rooms (free area not less than 8% of the area of the interior room nor less than 25 ftq) or can be considered directly ventilated (operable area of 4% of the floor area) if openings to the outdoors of the adjoining room are located within 8m (25ft) from the storage room?
