Instances in which building occupants experience acute health and discomfort 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. 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.
