Current through Register Vol. 51, page 10, July 15, 2024
The ventilating systems shall maintain temperatures total
				  air changes as follows:
(1) For all
				other occupied areas, the facility shall be able to maintain a minimum
				temperature of 75 degrees Fahrenheit (23.9 degrees centigrade) at winter design
				conditions with a minimum of at least two total air changes an hour. All air
				supply and air exhaust systems shall be mechanically operated. All fans serving
				exhaust systems shall be located at the discharge end of the system. Each
				mechanical ventilation systems shall 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. 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

				under 1000 square feet. A sign shall be posted at the front of each parking
				space advising the driver to shut off the engine.
(4) Each crawl space shall be provided with
				mechanical ventilation at least 0.5 air changes each day or be provided with
				open perimeter venting as required by the International Building Code.
A ventilation system using a recirculated central air system
				  shall be equipped with a minimum of two filter beds. Filter bed number one
				  shall be located upstream of the conditioning equipment and shall have a
				  minimum efficiency of 30 percent. Each supply air unit shall have a minimum of
				  30 percent effective filters. These filter efficiencies shall be warranted by
				  the manufacturer and shall be based on the ASHRAE 52.2, 2007 edition, American
				  Society of Heating, Refrigeration, and Air Conditioning Engineers dust spot
				  test method with atmospheric dust. Each filter frame shall be durable and
				  carefully dimensioned and shall provide an airtight fit with the enclosing duct
				  work. Each joint between filter segments and the enclosing duct work shall
				  contain a gasket or sealed to provide a positive seal against air
				  leakage.
