Zusammenfassung:	To provide a ventilation evaluation device and a ventilation evaluation method which can achieve safe operation of a room by quantifying ventilation capacity without hindering the use of the room.SOLUTION: A ventilation evaluation device 100 includes a control unit 10 for acquiring carbon dioxide concentration data from a carbon dioxide sensor 20 disposed in a room 200 having a ventilation facility. The control unit 10 estimates a ventilation frequency in the room 200 from a reduction value per unit time of the carbon dioxide concentration data at a timing when a person goes out of the room 200.SELECTED DRAWING: Figure 3 【課題】部屋の利用を妨げることなく換気能力を定量化して部屋の安全な運用を行うことが可能な換気評価装置及び換気評価方法を提供する。【解決手段】本開示に係る換気評価装置１００は、換気設備を有する部屋２００内に配置された二酸化炭素センサ２０から二酸化炭素濃度データを取得する制御部１０を備え、制御部１０は、部屋２００から人が退出したタイミングにおける二酸化炭素濃度データの単位時間あたりの減少値から、部屋２００内の換気回数を推定することを特徴とする。【選択図】図３
