In recent years, indoor volatile organic compounds (VOCs) and formaldehyde (HCHO) from interior finishing material are recognized as one of the most serious potential risks against human health. Authors carried out experiments to investigate the influence of interior finishing on indoor air quality. Three experimental rooms with different finishing material and adhesive were used to quantity the indoor air concentration and the decreasing rate of HCHO and VOCs. It is observed that the concentration of HCHO and VOCs decreased by approximately 58% and 89% as the minimum after one year from the completion of the rooms. In addition, a method for predicting the indoor air concentration of HCHO, using measured emission rate of HCHO from each specimen of the finishing material, was proposed.
