[0045] In step S13, according to the low-carbon evaluation model of electrical equipment and multiple trainings of weights in different dimensions, determine the corresponding comprehensive weight.
[0046] In the specific implementation process of the present invention, the specific steps are as follows: Step S131: In the low-carbon evaluation model of electrical equipment, construct an initial judgment matrix based on the past operation data of each electrical equipment, and determine the ANP initial weight of each influencing factor according to the initial judgment matrix .

[0084] In the airport application scenario, airport buildings usually have large spaces, high passenger flow densities, and complex equipment systems such as chillers, lighting systems, elevators, etc. The operation performance of the building equipment directly affects energy consumption and passenger comfort.

[0091] Implementation effect: The energy efficiency of school buildings has been increased by 21%, and energy consumption has been reduced. The comfort of students has been improved, and the learning environment has been enhanced.
[0092] Buildings are often designed in detail from different perspectives during the design phase. However, in actual use, they often do not operate as envisioned. For three-star buildings, zero-energy buildings, or zero-carbon buildings designed, there is no appropriate method to evaluate whether they can truly achieve the expected energy savings. Moreover, the requirements in design specifications are mostly for the virtual annual energy consumption, and there is no evaluation of the low-carbon effect under a certain period of time, a certain type of weather, a certain season, or a certain utilization rate of the building.
[0093] Through the method of the present invention, only a small amount of incomplete real-time building data training is required to achieve the assessment of the building's energy-saving situation, thereby improving the efficiency and practicality of the assessment, and filling the gap in the lack of immediate evaluation based on actual data during the building operation and maintenance stage. With the advancement of building digitization, this method can be more conveniently implemented and provide a real and effective database for various types of buildings.
[0094] In addition, based on the factory data of equipment, different specifications, and data from different building platforms, a low-carbon evaluation model for equipment is constructed. The ANP method, LSTM, and entropy weight method combined with the attention mechanism are used to triple-correct the coefficients. This improvement enhances the model's attention to key information, accelerates the model's convergence process, successfully reduces the number of training times, and simultaneously improves the accuracy and reliability of the model results. Through the progressive weight optimization process of ANP (initial weight) → entropy weight method (objective correction) → LSTM (dynamic adjustment) → attention mechanism (fusion weight), a closed-loop feedback is formed, significantly enhancing the scientific nature of the evaluation.
[0095] In multi-source data fusion, the real-time operation data, environmental data (temperature, humidity, wind speed), and usage data (number of people, schedule) of multiple devices in the building, such as chiller hosts, lighting systems, and elevators, are integrated, breaking through the limitations of traditional single-data-source evaluation. Traditional methods usually rely on a single data source and may have biases. Multi-source data fusion can significantly improve the accuracy and reliability of the evaluation.
[0096] In the dynamic weight adjustment mechanism, LSTM transfer learning is combined to predict time-series data and dynamically correct the weights, solving the defect that traditional static models such as ANP cannot adapt to real-time changes. Traditional methods usually use static weights and are difficult to adapt to the changes in real-time data. Dynamic weight adjustment can respond more flexibly to changes in the operating environment.
[0097] In the entropy weight method and the attention mechanism, based on the information entropy of multi-source data, the LSTM prediction results, the weights corrected by the entropy weight method, and the ANP initial weights are fused through the attention mechanism to obtain a more scientific comprehensive weight. The entropy weight method enhances the objectivity of the weights, and the attention mechanism can more scientifically fuse weights from different sources, improving the scientificity and accuracy of the evaluation.
[0098] In real-time performance evaluation and optimization, based on the fused weights, the overall performance score of the building is calculated in real-time, and targeted efficiency improvement suggestions are generated.
