| Currently our country is in the rapid development phase of industrialization,post-industrialization and urbanization,and the continuous increase of urban population further speeds up the energy consumption of resources and demand growth.The proportion of building energy consumption in total energy consumption society also increased year by year,which has become an important factor restricting the sustainable development of society.In addition to the efficiency improvement of the supply side,reasonable guidance of demand side is the key to realize building energy efficiency as well.In order to realize building energy conservation mode transformation from supply side to demand side,it is essential to properly describe the specific energy characteristics of indoor environment,which can help to assess the rationality of the building energy consumption from the demand side and accurately identify the cause of energy waste.Based on the research of indoor spatial awareness theory,combined with the analysis model of energy consumption,indoor spatial awareness model is put forward from the perspective of energy planning and management,and then the model is applied to building energy management.Finally the design of indoor spatial awareness energy information management database is completed.The main contents of this article are as follows:1.Aiming at the characteristics of all kinds of analysis model in the assessment of building energy consumption,this paper put up with the theory of indoor spatial awareness.The indoor spatial awareness is divided into three parts according to the effect on building energy consumption,namely environment awareness,energy awareness and context awareness.Then the concept,research contents,elements,information acquisition methods of each part are defined,forming a complete set of building energy consumption analysis framework.2.The indoor spatial awareness model is applied to building energy management,and thebasic analysis process is put forward.Taking office environment as an example,the sensor placement for each subsystem and information acquisition methods are introduced.After data preprocessing,combined with indoor spatial awareness model analysis process and data mining methods,the operation pattern of building energy consumption and the relationship between energy consumption influence factors are mined and found.Finally aiming at improper behavior,the suggestions for improvement are put forward,which verifies the effectiveness of the proposed model.3.The design of indoor spatial awareness energy information management database is completed,including the selection of database management tools,the demand analysis,database concept structure design,database logic structure design,the establishment of the database and other steps.Combined with indoor spatial awareness model,the key design points and the design process of each part are introduced in detail,and then the design of information management database table and establishment of relationships between tables are completed.Finally taking the Weka data mining software as an example,the connection and call of information management database are completed through interface driver,providing data information supporting for the use of data mining methods in analyzing indoor spatial awareness model.The research results show that compared with other energy consumption analysis model,indoor spatial awareness model is more comprehensive in summarizing building energy consumption influencing factors.Through the cooptating of all factors into the model with the purpose of implementation and optimization the model can lead to explore energy-saving potential and provide theoretical basis on highly efficient management for building. |
