| Research Abstract |
An indoor air quality (IAQ) model for predicting volatile organic compound (VOC) concentration in rooms was developed to investigated the strategies for removal and control of pollutants from building materials.
To investigate the possibility of IAQ control by hybrid ventilation and building material sorption in houses, the sensitivity analysis for an IAQ prediction model coupled with source/sink model was performed, the performance of IAQ control for a full-scale test house installed with the hybrid ventilation system to remove contaminants was evaluated and the sink effect of building materials by computer simulation was investigated.
The adsorption and desorption rate constants related to the sink effect of building materials used in Japanese ordinary houses, were obtained by the nonlinear regression analysis for the experimental data using a small chamber. The sensitivity analysis related to the sink effect of the building materials for an IAQ model in consideration of sink effect based on the Langmuir isotherm for a single room was carried out to clarify the characteristics of the sink effect.
Moreover the performance of the hybrid ventilation system with/without air-filter to remove pollutants in the full-scale test house furnished with the different materials was evaluated to control IAQ by simulation using a multi-zone IAQ model based on the ventilation network theory.
