Abstract
Reinforcing the insulation and airtightness of buildings and the use of building materials containing new chemical substances have caused indoor air quality problems. Use of sorptive building materials along with removal of pollutants, constant ventilation, bake-out, etc. are gaining attention in Korea and Japan as methods for improving such indoor air quality problems. On the other hand, sorptive building materials are considered a passive method of reducing the concentration of pollutants, and their application should be reviewed in the early stages. Thus, in this research, activated carbon was prepared as a sorptive building material. Then, computational fluid dynamics (CFD) was conducted, and a method for optimal installation of sorptive building materials was derived according to the indoor environment using the contribution ratio of pollution source (CRP) index. The results show that a method for optimal installation of sorptive building materials can be derived by predicting the contribution ratio of pollutant sources according to the CRP index.

This study evaluated the improvement in pollutant inhalation rate by occupants after the application of sorptive building materials using the CRP index proposed by Hayashi et al [10]
Summary
Reinforcing the insulation and airtightness of buildings and the use of building materials containing new chemical substances has caused indoor air quality problems, such as sick house syndrome, affecting the health of residents and causing economic loss through work efficiency loss. The International Organization for environmental variables, including temperature, relative humidity, amount of ventilation, loading factor, and mass transfer coefficient, is essential for comparing sorptive building materials [5]. Computational fluid dynamics (CFD) analysis does not reviewed advance so that thethe pollutant concentration reducing performance theoptimal sorptive building cause anyin risks resulting from experiment and has the advantage of derivingofan installation materials can be maximized. Inofaddition, onwhich these has been CFD provenanalysis to have awas significant effectto on evaluate reducing indoor pollutant concentration, wasaround conducted results, conducted the concentration of pollutants an and the sustainability of the performance analyzed On these results, occupant’s breathing area according to thewas air diffuser method inside based the space resulting fromCFD the analysis wasofconducted to evaluate the concentration of pollutants around and an occupant’s breathing installation sorptive building materials and the posture of the occupant, methods for optimal area according to the air diffuser method inside the space resulting from the installation of sorptive installation of sorptive building materials for reducing pollutant inhalation volume of an occupant building materials andthe theCRP posture of the occupant, and methods for optimal installation of sorptive were reviewed using. Building materials for reducing pollutant inhalation volume of an occupant were reviewed using the CRP
