Many areas focus on energy saving according to the decreased amount of finite resources and increased interests of alternative recourses and energies. As a result, Many apartments have only installed ventilation systems in underground parking lots and aren't operating machine ventilation systems to save money, causing pollution of indoor air quality in underground parking lots. Since most modern people have their own cars, we studied indoor air pollutants in underground parking lots, which are used by a large number of people at a particular time, unlike residential spaces and office spaces. The results of the measurement show that Rn, CO2, CO varies depending on the presence of the ventilation system, and shows the necessity of ventilation at times when comparing the indoor air quality of each parking lot, such as rush hour. |
