Building-Related Illness (BRI) refers to illnesses directly attributable to airborne contaminants found within buildings. It encompasses a range of health issues that occur as a direct result of exposure to indoor pollutants, such as mold, bacteria, chemicals, and other toxins. Unlike Sick Building Syndrome (SBS), which involves non-specific symptoms without identifiable causes, BRI can be clinically diagnosed with clear linkages to specific indoor pollutants.
Historical Context
The concept of BRI gained significant attention during the late 20th century as indoor air quality became a major public health concern. The oil crisis of the 1970s led to tighter building constructions to conserve energy, which inadvertently reduced ventilation and increased the accumulation of indoor pollutants. This period saw an upsurge in reported cases of building-related illnesses.
Types/Categories
Biological Contaminants
- Mold and Fungi: Aspergillus, Penicillium, and Stachybotrys are common indoor molds associated with respiratory issues.
- Bacteria: Legionella pneumophila, the bacteria responsible for Legionnaires’ disease, often proliferates in building water systems.
Chemical Contaminants
- Volatile Organic Compounds (VOCs): Chemicals like formaldehyde and benzene, found in building materials, furnishings, and cleaning products.
- Pesticides: Used for pest control but can lead to respiratory problems and other health issues.
Physical Contaminants
- Asbestos: Historically used in construction materials and now known to cause lung cancer and mesothelioma.
- Radon: A radioactive gas that can seep into buildings from the ground and cause lung cancer.
Key Events
Legionnaires’ Disease Outbreak (1976)
An outbreak at the American Legion convention in Philadelphia led to the discovery of Legionella bacteria in the building’s cooling tower, highlighting the dangers of poor building maintenance and indoor air quality.
Detailed Explanations
Symptoms of BRI
BRI can manifest in a range of symptoms depending on the contaminant. Common symptoms include:
- Respiratory issues: Coughing, wheezing, shortness of breath
- Neurological symptoms: Headaches, dizziness, cognitive difficulties
- General symptoms: Fatigue, fever, and muscle aches
Diagnosing BRI
Medical professionals rely on environmental assessments and medical testing to diagnose BRI. Identifying the specific contaminant and the patient’s exposure history is crucial.
Mathematical Models/Formulas
Air Exchange Rate Formula
The rate of air exchange in a building is crucial for understanding the potential accumulation of contaminants:

Importance
Understanding and mitigating BRI is vital for public health. Poor indoor air quality can lead to chronic health issues and reduce productivity. Employers, building managers, and policymakers must prioritize indoor air quality to ensure the well-being of occupants.
Applicability
BRI is relevant in various settings, including:
- Residential buildings
- Office buildings
- Schools
- Hospitals
Examples
Case Study: Mold in a School
A high school in Texas experienced a mold infestation due to water damage. Several students and staff reported respiratory problems. An environmental assessment revealed high levels of Aspergillus and Penicillium, confirming the case of BRI.
Considerations
When addressing BRI, consider:
- Regular maintenance of HVAC systems
- Use of low-emission building materials
- Adequate ventilation and air filtration
- Prompt remediation of water damage
Related Terms
Sick Building Syndrome (SBS)
A condition where occupants experience non-specific symptoms linked to time spent in a building, without identifiable causes.
Indoor Air Quality (IAQ)
The quality of the air within buildings, influenced by pollutants, ventilation, and building operations.
Comparisons
BRI vs. SBS
- BRI: Clinically diagnosable, with identifiable pollutants.
- SBS: Non-specific symptoms, no clear cause.
Interesting Facts
- The term “sick building syndrome” was coined by the World Health Organization in 1986.
- Buildings constructed post-1970s energy crisis are more prone to indoor air quality issues due to tighter constructions.

Summary
Building-Related Illness (BRI) is a critical public health issue directly attributable to airborne contaminants found within buildings. With historical context, detailed explanations, models, and practical examples, understanding BRI is essential for improving indoor air quality and safeguarding public health. Through proactive measures and continued research, the impact of BRI can be significantly mitigated.
