A research into Sick Building Syndrome who suffers more male or female - Coursework ExampleWhen twenty per centum or more of a creates occupants complain of these conditions, it is said that these individuals may be suffering from sick building syndrome (Akovali, 2007).Sick building syndrome is described as a condition wherein a throng of people in the same building or similar structure experiences acute wellness symptoms which improves or disappears once they go out of the building. These symptoms include headache irritated eyes, nose, and throat cough dry and tense skin dizziness and nausea inability to concent treasure sensitivity to odours and fatigue. Its underlying cause remains unclear. as yet most attribute the phenomenon to inadequate building ventilation, contaminants and stress (Fraser, 2008). According to the study by Bischof and Bullinger (1998), symptoms of sick building syndrome were reported on both air-condition and naturally-ventilated buildings. However, inci dents of SBS were more evident in poorly maintained air-conditioned buildings.Inadequate 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 1970s caused a reduction of ventilation rate to 5 cfm. The reduced flow of open-air(prenominal) air was discovered to cause discomfort and acute health symptoms among the buildings occupants. In order to minimize energy use and attain an acceptable interior 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 v ehicle fumes, plumbing and building exhausts
