Sick Building Syndrome (SBS) comprises of various nonspecific symptoms that effect the occupants of a specific building, home, or office. These symptoms increase sickness absenteeism and cause a decrease in productivity.

When a building has SBS the occupants experience acute health or comfort-related effects that seem to be linked directly to the time they spend in the area. The complaints may be localized in a particular room or zone or may be widespread throughout the entire building depending on the levels of contamination. The indicators of SBS include but are not limited to headaches, eye, nose and throat irritations, dry cough, dry or itchy skin, dizziness, nausea, difficulty in concentrating, fatigue and sensitivity to odors. In most cases, after exiting the building or area of concern, occupants begin to feel better.
