The National Institute for Occupational Safety and Health (NIOSH) and the U.S. Army, Construction Engineering Research Laboratory (USA-CERL) have collaborated on a project that examines the influence of heating, ventilation, and air-conditioning (HVAC) system operational parameters on the levels of microorganisms found in a simulated office space. In these experiments, fungi were collected as representative microorganisms using side-by-side sieve and slit samplers. Experiments at USA-CERL demonstrated that fan coil units are a major source of fungal aerosols in the built environment. Fungal levels in simulated office space are affected by zone air change rates.
