Is your office making you sick? The hidden cost of poor indoor air quality.
Sick building syndrome describes a range of ailments, from headaches to respiratory distress, triggered by the environments where we work and live. While often dismissed as mere stress, the physical reality of our buildings—from ventilation rates to chemical outgassing—can significantly impact both our health and our professional productivity.
Sick building syndrome (SBS) is a condition where occupants develop symptoms like nausea, dizziness, and irritation due to their environment. Unlike building-related illness (BRI), which involves specific, diagnosable agents like Legionella pneumophila, SBS is often characterized by non-specific complaints that improve when the individual leaves the building. The causes are multifaceted, ranging from volatile organic compounds (VOCs) released by construction materials to inadequate ventilation and biological contaminants like mold.
The economic impact of these environments is substantial. Research indicates that low ventilation rates correlate with higher rates of short-term sick leave, with one study estimating a cost of $480 per employee annually. Furthermore, productivity is tied to air quality; increasing ventilation rates has been shown to boost production by 1.7% for every two-fold increase. These physical factors are compounded by psycho-social stressors, such as high job demands and low support, which recent studies suggest may play a larger role in symptom prevalence than the physical environment alone.
Historical shifts in building standards have inadvertently worsened the problem. In 1973, in response to the oil crisis, ASHRAE reduced required ventilation from 10 cubic feet per minute per person to 5 cubic feet per minute. This change was later identified as a contributor to SBS. Today, addressing these issues requires a combination of better maintenance, such as frequent HVAC servicing and the use of HEPA filtration, alongside thoughtful design that prioritizes natural light and individual control over the workspace.
While some interventions, like high-ozone shock treatments, remain popular despite evidence of their ineffectiveness, the focus is shifting toward measurable improvements. Whether it is replacing water-stained materials or ensuring proper air exchange, the goal is to mitigate the environmental triggers that overwhelm the immune system. As we spend more time in modern, sealed structures, understanding the interplay between our health and our architecture is no longer optional—it is a necessity for both well-being and economic efficiency.
