Based on the observation, we examined an indoor airflow and detailed distribution of age of air at main building of the National Museum of Western Art. Also from the view of the recovery of the authenticity which is important world heritage registration, we predicted the event that glass board partitions which didn't exist the original design were to be removed by using CFD. We confirmed actual measurements of air age distribution and the reproducibility of CFD analysis results in the current condition. And if the partition were to be reverted, it is fear that outdoor air come in the 19th century hall.
