Causes
The causes of Sick Building Syndrome can be attributed to inadequate ventilation, chemical contaminants from indoor or outdoor sources, as well as biological contaminants. Many volatile organic compounds, which are considered chemical contaminants, can cause acute effects on the occupants of a building. "Bacteria, molds, pollen, and viruses are types of biological contaminants," and can all cause SBS. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recently revised its ventilation standard to provide a minimum of 15 cfm of outdoor air per person (20 cfm/person in office spaces). In addition, pollution from outdoors such as motor vehicle exhaust, can contribute to SBS.
