Carbon dioxide concentration prediction system, carbon dioxide concentration prediction method, and computer readable medium

A carbon dioxide concentration prediction method comprising:

• predicting, by a prediction unit, based on a current carbon dioxide concentration of an internal space in a prediction target and environment information in the prediction target, a carbon dioxide concentration of the internal space;
• and
• providing, by a provision unit, the carbon dioxide concentration predicted in the predicting, wherein
• the internal space contains a gas including carbon dioxide,
• the environment information further includes air flow information in the internal space,
• the air flow information includes at least one of information of a supply unit configured to supply an external gas outside the internal space to the internal space or information of an exhaust unit configured to evacuate an internal gas that is the gas in the internal space to outside of the internal space,
• the information of the supply unit and the information of the exhaust unit include an expense from an operation of the supply unit and the exhaust unit,
• the predicting includes predicting, by the prediction unit, at least one of a first concentration that is the carbon dioxide concentration in a current operation state of the supply unit and the exhaust unit, a second concentration that is the carbon dioxide concentration in a case where at least one of the supply unit or the exhaust unit has changed from the current operation state, or the expense in a case where the carbon dioxide concentration is the second concentration, and
• the providing includes providing, by the provision unit, at least one of the current carbon dioxide concentration, the first concentration, the second concentration, or the expense.

A computer readable medium having recorded thereon a program that, when executed by a computer, causes the computer to perform operations comprising:

• predicting, based on a current carbon dioxide concentration of an internal space in a prediction target and environment information in the prediction target, a carbon dioxide concentration of the internal space, wherein
• the internal space contains a gas including carbon dioxide,
• the environment information further includes air flow information in the internal space,
• the air flow information includes at least one of information of a supply unit configured to supply an external gas outside the internal space to the internal space or information of an exhaust unit configured to evacuate an internal gas that is the gas in the internal space to outside of the internal space,
• the information of the supply unit and the information of the exhaust unit include an expense from an operation of the supply unit and the exhaust unit,
• the prediction unit is configured to predict at least one of a first concentration that is the carbon dioxide concentration in a current operation state of the supply unit and the exhaust unit, a second concentration that is the carbon dioxide concentration in a case where at least one of the supply unit or the exhaust unit has changed from the current operation state, or the expense in a case where the carbon dioxide concentration is the second concentration;
• and
• providing the carbon dioxide concentration predicted in the predicting, wherein the providing includes providing at least one of the current carbon dioxide concentration, the first concentration, the second concentration, or the expense.
