According to statistics, the current building energy consumption accounted for 26.7% of China 's total energy consumption energy consumption . With the tension between energy supply and demand , reduce building energy consumption has not only economic issues , but also related to the problems of the national strategy . Therefore , the study of building energy efficiency is very important . This paper proposes a method based on the physical model of the measured thermal parameters field reconstruction , trying to find the law of the energy consumption of the building , in order to reduce building energy consumption to contribute for the lack of building energy efficiency at this stage of research methods . This paper first introduces the subject, background and significance , Building Energy Research Development Status , illustrates the importance of building energy efficiency and urgency , introduce several methods and research status of traditional building energy efficiency , the the flow numerical reconstruction technology development status and applications in the field of building energy efficiency . This background , building physics model based on thermal parameters field to carry out real-time reconstruction of the building energy-saving diagnostic study . Subsequently completed online real-time monitoring system design, and describes the overall system design , system hardware and software features , system implementation process and system database design . On this basis , the use of computational fluid dynamics numerical reconstruction of the thermal parameters within the field of architectural models . ROOM thermal equilibrium model , based on the knowledge of heat transfer within the building model to simulate different weather environment for the experimental analysis , draw energy flow and transfer law , pointed out that the the thermal defect site to complete the work of building energy consumption analysis and diagnosis . Finally , the work is summarized , and pointed out that the course of the study there and make recommendations for further in-depth research .
