Abstract: Generally, the peoples are spending 90% of their time, in closed environments; 70% business and 20% homes. The main factors, which makes peoples sick are, isolated buildings where there is no internal air circulation for energy saving, the use of unhealthy building materials and poor ventilation systems. Sick Building Syndrome (SBS)presents it self with symptoms of discomfort, such as headache, cough, hoarseness, dizziness, mental fatigue, nausea, some all ergicreactions, mouth and eye dryness, odorandtasteper version, chest tightness, watery eyes, it chingandredness. Various studies have been demonstrated, for comfort and productivity; clean air inhalation, 40 to 60% relative humidity and around 20 0C temperature are needed. 20% performance loss in humans have been observed when the temperature reaches 26 0C. Indoor air quality is a combination of different parameters such as; temperature, humidity, oxygen, carbon dioxide and has a direct impact on the social life of human. When there quests to the health are provider in the United States are analyzed, the indoor air quality and SBS related diseases are located in rank 4. With in creasing urbanization in recent years it must be taken various precautions, in over dependent the possible adversely effects on people' slives. Efficient and proper indoor ventilation, heat and moisture balance have great importance. In addition, maintenance of the ventilation system must be done periodically and accurate. The purpose of this research is to determine the quality of indoor air belonging to the spaces in which different occupational groups work. In this scope, a bank in Artvin Province, a Family Health Center and the Student Office of Health Sciences Faculty were elected. The amount of CO2 was measured during the hours of indoor air quality in three different locations. The result is compared with there late standard and various solution proposals are presented to the related places at the end of the work |
