  • The concentrations of Volatile Organic Compounds(VOCs) and Formaldehyde(HCHO) for interior materials of new vehicles are estimated and recognized by using the simulation program known as IAQx. The concentrations of contaminants are estimated and evaluated by the ventilation rates of new domestic vehicles and the required ventilation rates for new vehicles are estimated through the given contaminant data. This study is conducted to compare the ventilation rates for the contaminants between the discontinuously ventilated new vehicles and the continuously ventilated new vehicles using the simulation program. The equation of ventilation rate of new vehicles is acquired to be able to lower initial concentrations below the standard level under different conditions for both business and personal commuting.

  • The purpose of this study is to evaluate indoor air quality at the stage of building construction. To check the IAQ at the stage of construction IAQX simulation program developed by EPA was used and the values of TVOC were analyzed with time-series. The Simulation conditions are as follows. 1) Ventilation rate, 2) Time schedule of works, 3) Material change. Through this simulation, the major factors which affect the IAQ were analyzed and the importance of empirical data about the time-series emission rate of concerned material could be confirmed.
