Causes of Sick Building Syndrome
There are many theories on what causes sick building syndrome. Commonly cited causes are inadequate ventilation, chemical contaminants from indoor sources, and chemical contaminants from outdoor sources.
Inadequate ventilation is one of the most often cited reasons. Prior to the energy crisis in the 1970s, most buildings were not sealed up as tightly and circulated air more frequently. After the energy crisis, buildings were made more energy efficient by sealing up areas where air leaked into or out of the building. Additionally, airflow was decreased in many buildings from 15 cubic feet per minute to 5 cubic feet per minute.
Common chemical contaminants inside the building are found in paint, adhesives, carpeting, cleaning agents, and upholstered furniture. These chemicals can emit volatile organic compounds (VOCs).
Common chemical contaminants from outside of the building can include exhaust from motor vehicles and other industrial plants in the area.
