건물 환기시스템의 국내외 연구동향

Until recently, almost all residential buildings in South Korea conducted the natural ventilation based on the difference of pressure and air density between indoor and outdoor. However it has been difficult to supply the ventilation requirement by natural ventilation method with the emergence of high-rise apartment buildings. Moreover the rapid development of thermal insulation for the energy conservation performance improved the airtightness of the buildings. It occurs the deficiency of fresh air and aggravates the indoor air pollution problem. The sick building syndrome is also caused by the shortage of ventilation in the building. Therefore, it is necessary to supply a sufficient amount of ventilation to main tain a healthy indoor air quality. In this study, ventilation standards and research trend for building in Korea and abroad were investigated according to the ventilation method.
