Sick Building Syndrome (SBS): Source www.epa.gov/iaq/pubs/sbs.html
The term "sick building syndrome" (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that
appear to be linked to time spent in a building, but no specific illness or cause can be identified. The complaints may be localized in a particular room or zone, or may be widespread throughout the building.

Indicators of SBS include:

• Building occupants complain of symptoms associated with acute discomfort, e.g., headache; eye, nose, or throat irritation; dry cough; dry or itchy skin; dizziness and nausea; difficulty in concentrating; fatigue; and sensitivity to odors.
• The cause of the symptoms is not known.
• Most of the complainants report relief soon after leaving the building.
