Based on the existing passive building networking system, this paper unifies the data format, combines the spark computing engine with the prediction, timing and other algorithm models, deeply analyzes the energy consumption, environment and other data, and excavates the data value; The dual client design of web and Android can meet users' needs and bring users a more comfortable experience. The scheme has the advantages of strong standardization and high compatibility, and can bring efficient and stable energy-saving benefits to passive building operation and maintenance.
