The recent indoor air quality problem is a result of the improvement of building's airtightness and the use of building material containing chemicals. As a result of the increase of chemical materials and insufficient ventilation, Indoor air quality becomes worse and it is caused the harmful effects on health of occupants which is called Sick House Syndrome. To improve the indoor air quality is the most effective solution which is the use of the healthy environment materials but the second solution is dilution the pollution by the fresh outdoor air as ventilation. This experiment is recognized the variation of concentration of pollutants by the ventilation time in newly built apartment which is set up ventilation unit. We found that the concentration variation rate of HCHO and Toluene was increased rapidly in 1 hour and the effect of IAQ improvement by an air change rate is very effective.
In this experiment, the general building materials which emit pollutants was used, however, we will have to conduct above the experiment by using the healthy environment materials to obtain a proper ventilation requirement and ventilation time by the feature of material selection in the apartment built newly.
