Energy efficiency evaluation and diagnosis analysis method used for green public building operation phase

Abstract

The present invention relates to the technical field of green building energy efficiency evaluation methods, in particular to an energy efficiency evaluation and diagnostic analysis method for green public A diagnostic analysis method for building energy efficiency; an energy efficiency evaluation method for the operation phase of the green public building. The method of the present invention has real-time and versatility: a hierarchical evaluation index system that characterizes the operating state of the green building is established relatively completely, through the processing of operating data and historical data, corresponding monitoring indicators and statistical indicators can be determined, and based on The comparison of design data and evaluation benchmarks of relevant standards and specifications can comprehensively evaluate the energy utilization level of green buildings in the operation stage; at the same time, the method of the present invention can carry out classified diagnosis according to the factors affecting energy efficiency in operation, and carry out process-based diagnosis according to the influence rules, providing Reasonable suggestions for optimizing operation.

Description

technical field [0001] The invention relates to the technical field of green building energy efficiency evaluation methods, in particular to an energy efficiency evaluation and diagnostic analysis method used in the operation phase of green public buildings. Background technique [0002] According to statistics, in my country's energy consumption structure, the proportion of building energy consumption has exceeded one-third of the total energy consumption. With the acceleration of urbanization, the proportion of building energy consumption continues to rise. Building energy consumption is always high. At the same time, our country is also facing the dual pressure of energy shortage and environmental deterioration, and building energy conservation and emission reduction is imminent. Therefore, vigorously developing green building technology, and implementing scientific monitoring and optimizing management in the operation stage have become the key to realizing building energ...

Problems solved by technology

[0003] At present, many public buildings are designed and constructed in accordance with the technical requirements of green buildings, and energy consumption monitoring platforms have also been established, and a large amount of data has been accumulated in the operation process. The energy utilization efficiency lacks effective assessment and energy-saving diagnosis, and has not formed the effect of optimized operation

[0004] In the prior art, on the one hand, the analysis and processing of building energy consumption monitoring data focuses on how to reasonably eliminate and intelligently supplement problematic data (such as Chinese patent CN1O4199961A), on the other hand, it focuses on how to determine building energy consumption distribution based on energy consumption data Announcement of status and energy efficiency level and implementation of abnormal alarm function (such as Chinese patent CN103412551A and Chinese patent CN10249594A), there is no analysis on the evaluation of the contribution of renewable energy application technology in the operation of green public buildings, and there is no effective use of energy in the operation process Correlation analysis between the situation and its influencing factors, correspondingly, there is no analysis on the optimal operation management of building energy-using systems or equipment based on the analysis of influencing factors
