Abstract

This invention relates to the field of energy consumption monitoring technology, specifically to a building energy conservation assessment system and method based on energy consumption monitoring. The system includes an energy consumption sequence construction module, an energy efficiency status quantification module, an abnormal energy consumption element location module, and an energy conservation scheme evaluation module. By collecting building energy consumption data and driving data such as external environment and internal operation, a contextualized data sequence is constructed. A dynamic energy consumption benchmark model is established based on historical data. The energy efficiency health level is calculated and compared with a diagnostic threshold determined through nonparametric kernel density estimation to determine energy consumption anomalies. When anomalies are present, the contribution of each element in the context vector to the energy consumption deviation is quantified to locate the main anomaly source. An energy conservation scheme is generated based on the anomaly elements. The energy conservation effect is predicted through dynamic model simulation and compared with the threshold to evaluate the effectiveness of the scheme, thereby achieving accurate diagnosis and energy conservation optimization of building energy consumption.
