Fahrenheit above ambient room temperature.
(d) All rooms and occupiable areas in the
facility shall have provisions for ventilation. Natural window ventilation may

of temperature extremes. Outside ventilation air shall be tempered to between
room temperature and the supply air temperature for the appropriate heating or
cooling mode.

with a minimum of 25% efficiency.
(k) Gravity exhaust may be used where
conditions permit for boiler rooms, central storage, and other nonresident
