Abstract: To utilize building energy consumption monitoring data of various granularity for big data analysis，indi- cators on building energy consumption were collected from national standards，guidelines and existing research． Da- ta used to calculate those indicators and the interrelationships of these data were identified． By using object-oriented method，an overall model of building energy consumption information was established and the information model of building energy consumption monitoring data of different granularity for big data analysis was built from three as- pects，forming the building energy consumption information model． Based on the model，the MongoDB database management system is used to establish a database for big data analysis to verify the feasibility of the model． This study makes it possible to make full use of building energy consumption monitoring data of different granularities for big data analysis．

Key words: building energy consumption, information model, energy consumption monitoring, big data analysis
