英文摘要	Occupant behavior is one of the most important factors influencing the level of energy con-sumption in the operational phase of buildings. The unique climatic conditions of the Qinghai -Tibetan plateau differ from those of lower altitude areas. Therefore, to specifically investigate the characteristics of the active heating behavior of the inhabitants of these areas, four house-holds are selected for this study. Each is equipped with a corresponding Air Source Heat Pump Air Heater (ASHP-AH) as their only heating equipment. The occupants' usage patterns and active regulating patterns are analyzed explicitly by clustering the ASHP-AH operational data of four households during the heating season using the K-means algorithm. The use of different time steps to reduce the dimensionality of the data and reduce the time and space complexity of the K-means algorithm in clustering is also discussed, and the Preference Cumulative Value (PCV) and Change Direction Frequency (CDF) are proposed to evaluate changes in the clustering results. These re-sults are potentially relevant to improving energy efficiency in relation to occupant behavior.
