Description

technical field [0001] The invention belongs to the technical field of building energy consumption analysis, and in particular relates to a method and device for monitoring carbon emissions of a building integrated energy system based on an EM-MFA algorithm. Background technique [0002] With the proposal of carbon peaking and carbon neutrality strategic goals, the importance and urgency of energy consumption analysis and energy conservation and emission reduction in the building sector have become increasingly prominent. The "Research Report on China's Building Energy Consumption and Carbon Emissions (2021)" pointed out that in 2019, the total energy consumption of the whole building process in China was 2.233 billion tons of standard coal. In 2019, the total carbon emission in the whole process of construction in China was 4.997 billion tons of carbon dioxide, accounting for 49.97% of the national carbon emission. Therefore, to propose a complete set of carbon emission mo...

Problems solved by technology

At the same time, the analysis of building energy consumption only stays in the energy consumption analysis of different types of energy systems. There is no unified unit and converted into carbon emissions, which cannot meet the carbon emission analysis needs of building comprehensive energy systems under the background of carbon peak and carbon neutrality.

[0009] The existing collection and transmission network of building energy consumption data has problems such as poor anti-interference, easy loss of energy consumption data, complicated networking process, and high networking cost.

Building energy consumption data is often lost due to problems such as network fluctuations or sensor failures

[0010] The carbon emission monitoring method and device of the existing building integrated energy system are relatively single in function, lacking a complete set of methods and devices for calculating, collecting, transmitting and storing carbon emission data throughout the building life cycle, and at the same time unable to realize building integrated energy. The system's real-time energy consumption monitoring, fault diagnosis and location, and building life cycle carbon emission simulation cannot provide data support for building energy consumption prediction, operation optimization and other technologies.
