Construction energy consumption analysis method and construction energy consumption analysis system based on BP neural network

Abstract

The invention discloses a construction energy consumption analysis method and a construction energy consumption analysis system based on a BP neural network. The method is characterized in that input output vector quantity can be determined according to predetermined construction energy consumption type; a BP neural network model can be constructed according to the input output vector quantity; the established BP neutral network model can be trained by inputting a training sample; the energy consumption index data requiring the analysis can be input in the trained BP model for the processing and the analysis; and the data restoration of the output data of the neutral network can be carried out. The system comprises an energy saving potential quantification module, a data preprocessing module, a BP network analysis module, a data restoration module, a configuration management module, and a log recording module. The processing and the analysis of the construction energy consumption index data can be realized quickly and accurately, and therefore the unreasonable links during the construction energy use process can be acquired, and then the construction manager and even the common user lack of professional knowledge can be aware of the construction energy consumption current condition and the energy saving improvement measures.

Description

technical field [0001] The invention relates to the detection and classification of building energy consumption data, belongs to the technical field of pattern classification, and particularly relates to a building energy consumption analysis method and system based on BP neural network. Background technique [0002] Building energy consumption analysis has always been the focus of attention and research by scholars from all over the world. Through correct and effective energy consumption calculation and analysis, the energy consumption of each link in the life cycle of buildings can be reduced. There are many building energy consumption analysis methods that can be used at present. According to the mathematical model, the calculation methods can be divided into two categories: one is the static energy consumption analysis method based on the stable heat transfer theory, and the other is the static energy consumption analysis method based on the stable heat transfer theory. ...

Problems solved by technology

In addition, this method has relatively high requirements for professional knowledge, and most of them are designed for professionals. For actual users of buildings or owners, property management and other personnel who do not have professional knowledge related to building energy systems, they cannot pass this method. This method has a basic understanding of the energy consumption of one's own house, so the practical application is greatly limited

[0005] Due to their own limitations, the above two traditional building energy consumption analysis methods do not make full use of the existing energy consumption data, fail to achieve intelligent analysis of energy consumption, and have limited support for energy-saving decision-making.
