Energy saving apparatus and air conditioner

When a user notification in accordance with energy-saving action, as a result, the user can not confirm the extent of the implementation of energy conservation, it is difficult to really feel the effects of energy conservation issues. Energy-saving equipment of the present invention includes: setting sensor input means input means input sensor information measured by the sensor information, the input setting information, based on the sensor information and the setting information generating energy-saving notification notification generation mechanism, the energy-saving report notification notification reporting agencies, based on the sensor detects the user information to save energy saving actions verification mechanism by the detected energy saving action is calculated to save energy saving evaluation value of the actual performance evaluation mechanism, to users saving the actual performance evaluation reporting agency report said energy-saving evaluation values.
