Evaluation of the indoor air quality at Hwangtoh house

The purpose of this study is to evaluate and compare the conditions of indoor air quality between Hwangtoh house and concrete house. Samples of this research are 3 concrete houses and 5 Hwangtoh houses, and analysis items are Formaldehyde(HCHO), Benzene, Toluene, Ethylbenzene, Xylene, Styrene. The results of this study are as follows. 1) Every level of 6 analysis items of indoor air quality at Hwangtoh house are satisfied the criteria which is the domestic recommendation standard of indoor air quality at multi-unit dwelling. 2) The indoor air of Hwangtoh house contains only 15% of Formaldehyde emission quantity of concrete house. 3) The indoor air of Hwangtoh house contains only 11% of Toluene emission quantity of concrete house. 4) The indoor air of Hwangtoh house contains only 0.3% of Ethylebenzene emission quantity of concrete house. 5) The indoor air of Hwangtoh house contains only 2% of Xylene emission quantity of concrete house. 6) The indoor air of Hwangtoh house contains only 4% of Styrene emission quantity of concrete house. 7) In case of Benzene, though the indoor air quality level of Hwangtoh house is enough satisfied the domestic criteria, but, the indoor air of Hwangtoh house contains it 11 times more than that of concrete house does. Those mean that the quality level of indoor air of housing is influenced by building materials, so we have to study and develop constantly about eco-friendly building materials.
