The modern workplace is often touted as a hub of innovation and productivity. But what happens when the very environment designed to foster these qualities becomes a source of illness? This is the reality of Building-Related Illness (BRI), a growing concern in environmental and water treatment.
BRI is defined as a condition where at least 20% of a building's occupants experience symptoms of illness for more than two weeks, with the source of these symptoms directly linked to a specific building feature or element. While the term "illness" might seem severe, BRI encompasses a wide range of ailments, including:
The underlying causes of BRI are diverse, often stemming from a combination of factors:
1. Poor Indoor Air Quality (IAQ): This is the most common culprit. Airborne contaminants like mold, dust mites, volatile organic compounds (VOCs), and bacteria can accumulate in buildings with inadequate ventilation systems, leading to respiratory and allergic reactions.
2. Water-Related Issues: Problems in water systems, including contaminated water sources, faulty plumbing, and inadequate disinfection, can lead to the growth of microbes and release of harmful chemicals. This can result in Legionnaires’ disease, humidifier fever, and other waterborne illnesses.
3. Building Materials and Furnishings: Certain building materials like glues, paints, carpets, and furnishings can release VOCs and other harmful substances into the air, causing irritation and long-term health problems.
4. Inadequate Ventilation: Buildings with insufficient air circulation can trap contaminants, leading to poor IAQ and the development of BRI symptoms.
5. Thermal Discomfort: Extreme temperatures, humidity levels, and lack of proper air conditioning can contribute to discomfort and create conditions conducive to microbial growth.
The impact of BRI on individuals and organizations is significant. It can lead to reduced productivity, absenteeism, and increased healthcare costs. Moreover, the psychological impact of feeling unwell in your workspace can be detrimental to employee morale and overall workplace well-being.
Prevention and Mitigation of BRI:
By addressing the root causes of BRI through comprehensive preventive measures and effective mitigation strategies, we can create healthier and more productive work environments. Environmental and water treatment professionals play a crucial role in ensuring the safety and well-being of building occupants by preventing and managing BRI.

Scenario: You are the building manager of a large office complex. You have noticed an increase in employee complaints regarding headaches, fatigue, and respiratory issues.
Task:
**Possible Causes:** 1. **Poor Indoor Air Quality (IAQ):** The complaints of headaches, fatigue, and respiratory issues could be caused by pollutants in the air such as mold, dust mites, or VOCs. 2. **Inadequate Ventilation:** If the ventilation system isn't working properly, contaminants could be trapped inside the building, leading to the symptoms described. 3. **Building Materials and Furnishings:** New carpets, paints, or furniture could be emitting VOCs, contributing to the health problems. **Investigation Plan:** 1. **Air Quality Testing:** Hire a professional to conduct air quality testing to identify specific contaminants in the air. 2. **Ventilation System Inspection:** Check the ventilation system for proper functioning and maintenance, including filter changes and air flow. 3. **Building Material Assessment:** Review recent building renovations or additions to identify any new materials that could be releasing harmful substances. **Action Plan:** **Addressing Poor IAQ:** * **Increase Ventilation:** Ensure proper air circulation by adjusting air flow settings and increasing air exchange rates. * **Air Filtration:** Install high-efficiency air filters to remove contaminants like mold, dust mites, and VOCs. * **Mold Remediation:** Conduct thorough mold inspections and remediation if necessary. **Addressing Inadequate Ventilation:** * **Ventilation System Maintenance:** Regularly clean and maintain the ventilation system, including filters and air ducts. * **Ventilation System Upgrade:** If necessary, consider upgrading the ventilation system to ensure adequate air circulation. * **Alternative Ventilation Strategies:** Explore solutions such as opening windows during cooler periods or utilizing portable air purifiers. **Addressing Building Materials and Furnishings:** * **Choose Low-VOC Materials:** Specify low-VOC materials for future renovations or furniture purchases. * **Off-gassing Reduction:** Allow new furniture and materials to off-gas in a well-ventilated area before bringing them into the building. * **Remove Problematic Materials:** If identified, remove or replace problematic materials or furnishings. **Note:** This is a sample solution. The specific causes, investigation plan, and action plan may vary depending on the building's unique characteristics and the available resources.
