Energy consumption monitoring control system and method for green building

The invention relates to the field of monitoring control, and particularly discloses an energy consumption monitoring control system and method for a green building. The method comprises the following steps: firstly, acquiring to-be-detected electric power energy consumption data values at a plurality of preset time points in a preset time period and electric power energy consumption data values under a normal operation condition, and obtaining to-be-detected electric power energy consumption feature vectors and normal electric power energy consumption feature vectors through a data arrangement module, a first feature coding module and a second feature coding module; and calculating a transfer matrix of the to-be-detected electric power energy consumption feature vector and the normal electric power energy consumption feature vector, optimizing the transfer matrix to obtain an optimized classification feature matrix, and finally enabling the optimized classification feature matrix to pass through a classifier
