An air-conditioning control evaluation apparatus that evaluates a plurality of controls for at least one air-conditioning related device disposed within a building, the air-conditioning control evaluation apparatus comprising: - a storage unit to store - building information on a building that includes an area where the air-conditioning related device is disposed, - device information including characteristics of the air-conditioning related device, - observed data including - information on an operational state of the air-conditioning related device, and - information on temperatures of the area and outside air, or information on both temperatures and humidities of the area and outside air, - control information on an evaluated control to be executed for the air-conditioning related device, - a set of building models including a plurality of building models, the plurality of building models representing thermal characteristics of the building or both thermal characteristics and humidity characteristics of the building, and - a candidate-model selection criterion representing a correspondence between a building model, and items included in each of the building information, the device information, and the observed data; - a data evaluation unit to determine an item available as input data for the building model from among the items included in each of the building information, the device information, and the observed data, and identify a type of distribution of the observed data; - a candidate-model selection unit to select, based on the item available as the input data and the candidate-model selection criterion, a plurality of candidate building models from the set of building models; - a parameter estimation unit to determine a parameter estimation method in correspondence with the type of distribution, and calculate, in accordance with the parameter estimation method, an estimated value for a parameter included in the plurality of selected candidate building models; - a model evaluation unit to calculate a predetermined statistic on the plurality of selected candidate building models, and determine, based on the statistic and a residual calculated for each of the plurality of selected candidate building models, one building model from the plurality of selected candidate building models, the residual being a residual between estimated and observed values of temperature or a residual between estimated and observed values of both temperature and humidity; and - an air-conditioning control evaluation unit to calculate, by using the building model determined by the model evaluation unit, an energy-saving evaluation value and a comfort evaluation value for the air-conditioning related device that result if each of the plurality of evaluated controls is executed. - a storage unit to store - building information on a building that includes an area where the air-conditioning related device is disposed, - device information including characteristics of the air-conditioning related device, - observed data including - information on an operational state of the air-conditioning related device, and - information on temperatures of the area and outside air, or information on both temperatures and humidities of the area and outside air, - control information on an evaluated control to be executed for the air-conditioning related device, - a set of building models including a plurality of building models, the plurality of building models representing thermal characteristics of the building or both thermal characteristics and humidity characteristics of the building, and - a candidate-model selection criterion representing a correspondence between a building model, and items included in each of the building information, the device information, and the observed data;
