A room temperature estimating device (10) includes a storage (13), a prediction formula producer (15), a prediction change obtainer (16), and a room temperature estimator (17). The prediction formula producer (15) produces, based on pieces of room temperature data and pieces of outside air temperature data corresponding to a specified time in each of two or more days during a given extraction period, which are stored in the storage (13), a prediction formulae expressing a relation between the pieces of the room temperature data and the pieces of the outside air temperature data at the specified time. The room temperature estimator (17) determines, based on a temporal change in outside air temperature obtained by the prediction change obtainer (16), an outside air temperature at a target date and time corresponding to the specified time, and applies the determined outside air temperature to the prediction formula, and thereby to estimate a room temperature at the target date and time. |
