Abstract
We have investigated the emission rates on many pollutant sources and the removal performance on countermeasure products agaist indoor air pollution. With this experimental exprience, we became to know the ideal building materials, furniture and the countermeasure technique or products to indoor air pollution. If we can indicate the clean air residence, it will decrease the sick building syndrome problems. So we aimed at proposing of the house designing techniques which offer healthy indoor air environment for us. And we realized to prediction method on the indoor chemical substance concentration. As a result, it showed that the indoor formaldehyde concentration was reduced by 75 percents with use of the paintless wooden flooring materials and the operation of effective domestic air cleaners.
