Sec. 3.76  Indoor housing facilities.

    (a) Heating, cooling, and temperature. Indoor housing facilities 
must be sufficiently heated and cooled when necessary to protect 
nonhuman primates from temperature extremes and to provide for their 
health and well-being. The ambient temperature in the facility must not 
fall below 45 [deg]F (7.2 [deg]C) for more than 4 consecutive hours when 
nonhuman primates are present, and must not rise above 85 [deg]F (29.5 
[deg]C) for more than 4 consecutive hours when nonhuman primates are 
present. The ambient temperature must be maintained at a level that 
ensures the health and well-being of the species housed, as directed by 
the attending veterinarian, in accordance with generally accepted 
professional and husbandry practices.
    (b) Ventilation. Indoor housing facilities must be sufficiently 
ventilated at

all times when nonhuman primates are present to provide for their health 
and well-being and to minimize odors, drafts, ammonia levels, and 
moisture condensation. Ventilation must be provided by windows, doors, 
vents, fans, or air conditioning. Auxiliary ventilation, such as fans, 
blowers, or air conditioning, must be provided when the ambient 
temperature is 85 [deg]F (29.5 [deg]C) or higher. The relative humidity 
maintained must be at a level that ensures the health and well-being of 
the animals housed, as directed by the attending veterinarian, in 
accordance with generally accepted professional and husbandry practices.
    (c) Lighting. Indoor housing facilities must be lighted well enough 
to permit routine inspection and cleaning of the facility, and 
observation of the nonhuman primates. Animal areas must be provided a 
regular diurnal lighting cycle of either natural or artificial light. 
Lighting must be uniformly diffused throughout animal facilities and 
provide sufficient illumination to aid in maintaining good housekeeping 
practices, adequate cleaning, adequate inspection of animals, and for 
the well-being of the animals. Primary enclosures must be placed in the 
housing facility so as to protect the nonhuman primates from excessive 
light.
