The animal research facility, also known as the vivarium, is a specially designed building type, which accommodates exquisitely controlled environments for the care and maintenance of experimental animals. Animal research facilities are related to but distinct from research laboratories. The facilities are complex, and expensive to build and to operate, but they are vital to the support of a proper, safe, and humane research effort.

The aims of The University of Mississippi’s Vivarium Animal Health Monitoring Program are early disease detection and treatment and the prevention of the spread of disease.

Vivariums (animal laboratories) within hospitals, universities, laboratories and research institutions, present special heating, ventilating, and air-conditioning (HVAC) commissioning challenges. Not only do vivariums require stricter air quality standards and controls within their own spaces and subspaces, they are usually housed within larger facilities, posing cross contamination issues.
