Air sealing is one of the most significant energy efficiency improvements, since an energy crisis in 1970s. But, a new problem by injurious gas that is bad for health from architectural materials by not carrying out natural ventilation is rising. Thus, recently it is concerned about the application possibility of photocatalyst.
The purpose of this study is to evaluate the photocatalyst's applicability as the environment-friendly building materials according to the intensity of ultraviolet ray and the fixing method of photocatalyst. As the results of this study, the inorganic photocatalyst type, one of the fixing methods of photocatalyst, is definitely superior to the other from the self-cleaning by ultraviolet ray point of view.
