Abstract
Evaluation of air quality by concentration of just only target compounds has the possibility of a lot of trouble. In this study, we evaluated the air quality of new nursery room. As a result, the TVOC concentrations greatly exceeded the indoor target value (400 μg/m3). Moreover, we verified various ventilation methods such as continuous running of kitchen fan, securing of ventilation routes and introduction of additional ventilating fan, and the concentration drastically decreased to one-tenth compared with opening status after 3 months. In addition, ventilation rates estimated by TVOC concentration change of PID monitor increased.
