The article discusses the basic principles of an automated system for monitoring long-term energy performance based on the open source OpenJEVis platform, gives a general idea of the overall system, the system architecture. OpenJEVis is an information system that realizes the possibility of obtaining and processing all kinds of physical data. The system has flexible mechanisms to collect, visualize and analyze all the key characteristics of its operations that determine energy. Under practical case energy production profile obtained by long-term consumption of thermal energy, identified the places unsustainable consumption, set the reasons for possible losses, visually identified in the behavior of the graph. The proposed approach to retrofits can give systematic enterprise results aimed at establishing strategies to improve energy efficiency and save resources.
