A research into Sick Building Syndrome who suffers more male or female - Coursework ExampleWhen twenty percent or more of a buildings occupants complain of these conditions, it is said that these individuals may be suffering from regurgitate building syndrome (Akovali, 2007).Sick building syndrome is described as a condition wherein a group of people in the same building or identical structure experiences acute health symptoms which improves or disappears once they go out of the building. These symptoms include headache irritated eyes, nose, and throat cough dry and itchy climb dizziness and nausea inability to concentrate sensitivity to odours and fatigue. Its underlying cause remains unclear. However most attribute the phenomenon to inadequate building ventilation, contaminants and stress (Fraser, 2008). tally to the study by Bischof and Bullinger (1998), symptoms of sick building syndrome were reported on both tune-conditioned and naturally-ventilated buildings. However, inc idents of SBS were more evident in poorly maintained air-conditioned buildings. lacking(predicate) building ventilation. At the start of the 20th century, building ventilation standards set the ventilation rate to 15 cubic feet per minute per occupant. However, the oil crisis in the seventies caused a reduction of ventilation rates to 5 cfm. The reduced flow of outdoor air was discovered to cause discomfort and acute health symptoms among the buildings occupants. In order to minimize energy use and attain an acceptable Indoor Air Quality level, the American National Standards Institute / American Society of Heating, Refrigerating, and Air-Conditioning Engineers had updated its ventilation standard to 20 cfm for office spaces (Environmental Protection Agency, 1991).Airborne contaminants. Ventilation systems for office buildings usually acquire air from the outside. As outdoor air gets inside the building, it also brings airborne contaminants. Sources of contaminants include motor veh icle fumes, plumbing and building exhausts
