Abstract
This research reports the investigation of actual conditions of the concentration of the indoor chemical before it constructs it in the recovery and after it constructs it.The concentration measurement after the recovery investigated a change with the lapse of time after six months one month later.The concentration before the recovery was all chemicals and very low values compared with the guideline value.As for the concentration after the recovery, a tendency different because of compared it on the condition before and after the furniture carrying and the condition of the ventilation equipment operation existence in each chemical was obtained.The source was considered by the chamber experiment compared with acquired data.
