Description

Technical Field

[0001] The invention relates to the technical field of building energy-saving transformation, and in particular to a comprehensive analysis method for energy-saving transformation of buildings. Background Art

[0002] There are two ways to define building energy consumption: broadly speaking, building energy consumption refers to the energy consumption of the entire process from building material manufacturing, construction, to building use. In a narrow sense, building energy consumption, that is, the energy consumption of building operation, is people's daily energy consumption, such as heating, air conditioning, lighting, cooking, laundry, etc., which is the dominant part of building energy consumption. With the growth of economic income and the improvement of quality of life, the focus of building consumption will shift from "hardware (decoration and durable consumer goods)" consumption to "software (function and environmental quality)" consumption, so the energy consumption required to ensure indoor air quality (air conditioning, ventilation, heating, hot water supply) will rise rapidly.

[0003] With the rapid development of science and technology today, energy issues, as one of the difficult problems in development, are increasingly being taken seriously. In the process of building new rural areas, rural energy-saving transformation is of great significance. Rural energy-saving transformation can effectively utilize resources, improve energy efficiency, and reduce waste, thereby more sustainably supporting rural life and production. Energy-saving transformation helps to reduce energy consumption, reduce the impact on the environment, and improve the rural ecological environment. It can reduce energy costs and improve energy utilization efficiency. By improving the energy efficiency of rural buildings, facilities and production processes, farmers can enjoy a more comfortable and safe living environment.

[0004] The prior art has the following defects or problems: The prior art publication number is: CN118153816A A comprehensive analysis method for energy-saving transformation of rural buildings includes the following steps: S1. Data collection and preprocessing; S2. Classification and analysis of the collected preprocessed energy consumption data; S3. Identification of high energy consumption items; S4. Comprehensive analysis;

[0005] The above equipment includes the key steps of the entire energy-saving transformation process during use, from energy consumption assessment to technical support, case sharing, security and privacy protection. It adopts real-time monitoring and data analysis to timely discover problems and adjust strategies to ensure the real-time and effectiveness of the transformation effect, build a knowledge base and case library, provide users with rich technical information and successful cases, promote experience sharing and technical exchanges, ensure data encryption storage, user privacy protection and permission management, and ensure the security of the system and the privacy of user data;

[0006] The above contents are not comprehensive enough to effectively evaluate the data of various factors of building energy consumption, make more comprehensive building renovation decisions, and effectively and accurately record building energy consumption information. In terms of construction, construction personnel are unable to complete the renovation according to the plan, and the renovation effect and efficiency cannot be guaranteed. There is no subsequent feedback mechanism, and it is impossible to provide reasonable feedback on the status of the building after the renovation, and it is impossible to make effective improvements based on the feedback content.
