What is Building Related Illness (BRI)?
Building related illness (BRI) is defined as the clinical manifestation of occupant exposure to excessive airborne pollutants in a building. The symptoms can be similar to SBS, but they can be clinically defined and their causes clearly identified. Legionnaire’s disease is one type of BRI. Occupants suffering from one of these afflictions must be away from the building for a prolonged period of time to realize significant improvement. Microorganisms, especially fungi, are implicated as primary and contributory factors.
