Sick Building Syndrome

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:photo

Building occupants complain of symptoms associated with acute discomfort, i.e., 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.

Building Related Illness

In contrast, the term “building related illness” (BRI) is used when symptoms of diagnosable illness are identified and can be attributed directly to airborne building contaminants.

Indicators of BRI include:

Building occupants complain of symptoms such as cough; chest tightness; fever, chills; and muscle aches. The symptoms can be clinically defined and have clearly identifiable causes. Complainants may require prolonged recovery times after leaving the building.

Indoor Air Quality Problems  Typically Originate From:

  • Unbalanced heating ventilation and air conditioning (HVAC) system,
  • Poorly maintained air filters and blowers,
  • Contamination of air ducts and air handling units,
  • Penetration of airborne contaminants into the building.
