The invention discloses an air conditioner energy-saving management method based on cloud sensing and user active intervention. The method comprises the following steps that internal and external temperature and humidity data of all buildings is acquired; daily load curves P and daily electric quantity curves Q of air conditioners are acquired; according to data of temperature and humidity daily curves, the daily load curves and the daily electric quantity curves of the air conditioners in each building, multi-dimensional energy efficiency ranking analysis is conducted according to geographicpositions and air conditioner types, and results are fed back to the air conditioners of each building; and the energy consumption data of the air conditioners in each building is compared, and if itis judged that the energy efficiency has improvement room, operation parameters of the air conditioners are adjusted so as to improve the energy efficiency level. According to the method, by means ofreal-time and accurate energy efficiency benchmarking, an administrator of an air conditioning system is assisted in knowing the energy efficiency level of the buildings in time, and optimal regulation and control are carried out actively.
