The previous paper (Part 1) proposed the concept of "equivalent material age" that uses the Arrheniusrelation and explained a method for long-term prediction of indoor volatile organic compound (VOC)concentration considering temperature dependence. This paper first describes the experimentconducted to validate the long-term concentration formula and the results of the experiment and reportson a comparison of the measured values obtained with the predicted values. The experiment wasconducted by a method conforming to JIS A1901:2003. The material measured was formaldehyde.

Sick building syndrome, which has become a major public concern in recent years, is caused in part byvolatile organic compounds (VOCs) emitted by building materials. In order to ensure the safety of ourenvironment, it is necessary to predict indoor VOCs concentrations over a long period of time.Long-term prediction of VOCs concentration requires the consideration of the influence of temperaturechanges, and there is a need for a simple prediction method that can be used for this purpose. Theprediction methods that have been proposed thus far, however, do not meet this requirement.
