For occupied areas, the facility shall maintain a minimum temperature of seventy-five degrees Fahrenheit, or 23.9 degrees centigrade, and at least fifteen percent humidity during winter conditions with a minimum of at least two total air changes per hour. All air supply and air exhaust systems must be mechanically operated. All fans serving exhaust systems must be located at the discharge end of the system. Outdoor ventilation air intakes, other than for individual room units, must be located as far away as practicable but not less than twenty-five feet, or 7.62 meters, from plumbing vent stacks and the exhausts from any ventilating system or combustion equipment. The bottom of outdoor intakes serving central air systems must be located as high as possible but not less than six feet, or 1.83 meters, above the ground level or, if installed through the roof, three feet, or .91 meters, above roof level. Each mechanical ventilation system must be designed and balanced to provide make-up air and safe pressure relationships between adjacent areas to preclude the spread of infections and assure the health of the occupants. Each room supply air inlet, air recirculation, and exhaust air outlet must be located with the grill or diffuser opening not less than three inches, or .08 meters, above the floor. A corridor may not be used to supply air to or exhaust air from any room, except that exhaust air from corridors may be used to ventilate bathrooms, toilet rooms, or janitor's closets opening directly on corridors. Continuous mechanical exhaust ventilation must be provided in all soiled areas, wet areas, and storage rooms. In unoccupied service areas, ventilation may be reduced or discontinued when the health and comfort of the occupants are not compromised.
Each cooking appliance, other than a microwave oven, must be provided with exhaust ventilation to the exterior of the building that is able to remove cooking odors, heat, and moisture.
Each vehicle parking garage must be provided with carbon monoxide detection to activate exhaust ventilation of six air changes each hour or to open the garage door if the area of the garage is under one thousand square feet. A sign must be posted at the front of each parking space advising the driver to shut off the engine.
Each crawl space must be provided with mechanical ventilation at least one-half air changes each day or be provided with open perimeter venting as required by the International Building Code, 2012 edition, section 1203.
