Building electricity energy-saving management method based on grey correlation

Abstract

A building electricity energy-saving management method based on grey correlation includes monitoring energy consumption of each energy consumption sub-item built in a time period and determining an analysis sequence; conducting non-dimensional conversion on the analysis sequence; calculating correlation coefficients and relevancy of a reference sequence and a comparison sequence in the analysis sequence; judging sub-items ranking higher according to the relevancy and conducting energy-saving optimum management on the sub-item energy consumption to reduce the sub-item energy consumption to reduce building total energy consumption to the largest extent and achieve energy-saving management of building electricity.

Description

technical field [0001] The invention relates to a method for energy-saving management of building electricity, belonging to the field of energy-saving management of building electricity. More specifically, it relates to a grey relation-based energy-saving management method for building electricity consumption. Background technique [0002] With the development of economy, my country's construction industry has developed rapidly, the scale of buildings has grown, and the energy consumption of buildings has continued to increase. According to the data released by the Energy Efficiency and Technology Office of the World Energy Agency, China's basic energy consumption accounts for one-tenth of the world's total consumption, ranking second only to the United States. Among them, the energy consumption of buildings in my country accounts for about 30% of the total energy consumption of the whole society in my country. It can be seen that buildings are major energy consumers. How ...

Problems solved by technology

In the document "Analysis of Energy Consumption of Office Buildings and Energy Saving Potential", the author proposes equipment energy saving and management energy saving. Energy saving management is not discussed

[0004] To sum up, the existing building energy efficiency management and energy saving and emission reduction mainly focus on building structure energy saving and equipment energy saving, while building operation management energy saving is relatively deficient.
