Description

Technical Field

[0001] This invention belongs to the field of building operation carbon emission monitoring technology, specifically a dynamic monitoring and display system for carbon emissions from building energy-saving building envelopes. Background Technology

[0002] The impact of energy-saving and efficiency-enhancing building envelope structures on operational energy consumption and carbon emissions after construction and commissioning should be specifically monitored in order to quantify their energy-saving and efficiency-enhancing effects.

[0003] Carbon emissions during the building's operation phase account for over 70% of its total life-cycle carbon emissions. The thermal performance of the building envelope directly determines heating and cooling loads, making it a key factor influencing operational carbon emissions. However, existing carbon emission monitoring technologies have shortcomings and cannot meet the actual needs of carbon emissions during the building envelope's operation phase. First, they cannot accurately attribute emissions: existing devices mostly calculate carbon emissions based on total building electricity consumption or total HVAC energy consumption, making it difficult to attribute carbon emissions to specific parts of the building envelope, resulting in a lack of data support for energy-saving retrofits and low-carbon operation and maintenance. Second, they have poor adaptability: traditional monitoring equipment is mostly external sensors, which are difficult to adapt to different building envelope forms such as curtain walls, roofs, and composite panels, and improper installation can easily lead to distorted measurement data. Third, they lack dedicated monitoring methods for the operation phase: existing devices mostly focus on the carbon footprint of building materials or total building carbon emissions, lacking real-time monitoring equipment for the thermal performance of the building envelope, and cannot dynamically reflect abnormal increases in carbon emissions caused by aging of the building envelope, shading failure, and sealing deterioration.

[0004] Therefore, a dynamic monitoring and display system for carbon emissions from building energy-saving envelopes is provided. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a dynamic monitoring and display system for carbon emissions from building envelopes that addresses the issues of existing devices being unable to accurately attribute operational carbon emissions to specific parts of the building envelope and lacking dedicated monitoring methods for the operational phase.

[0006] The technical solution to achieve the above objectives is: A dynamic monitoring and display system for carbon emissions from building envelopes designed for energy conservation includes: The housing, and the operation monitoring module, data processing module, communication module and power supply module disposed within the housing, wherein a touch screen display for displaying carbon emission data and energy saving comparison information is embedded on the surface of the housing, and the outer surface of the touch screen display is covered with a tempered glass layer; in, The operation monitoring module is used to collect thermal parameters of the building envelope and surrounding environment in real time. The data processing module is electrically connected to the operation monitoring module. It has a built-in carbon emission calculation model and a benchmark comparison model for calculating the real-time heat transfer coefficient, hourly heat load, operating carbon emission rate and accumulated carbon emission of the building envelope, and dynamically comparing them with the theoretical carbon emission value of the traditional building envelope. The communication module is electrically connected to the data processing module and is used to upload real-time carbon emission data to the building energy management platform, carbon management cloud platform or building automation system. The power supply module is electrically connected to the operation monitoring module, the data processing module, and the communication module, respectively, and is used to provide working power.

[0007] Preferably, the operation monitoring module includes: Indoor temperature sensor for real-time acquisition of indoor air temperature near the inner surface of the building envelope; An outdoor temperature sensor is used to collect the outdoor air temperature near the outer surface of the building envelope in real time. A heat flux density sensor is attached to the inner surface of the building envelope or embedded inside the building envelope layer to monitor the conduction heat flux density through the building envelope in real time. Solar radiation sensors, installed on the outer surface of the building envelope or flush with the roof, are used to monitor total solar irradiance in real time and correct for the impact of solar heat gain on operational carbon emissions.

[0008] Preferably, the operation monitoring module further includes indoor and outdoor humidity sensors and wind speed sensors to correct the heat transfer coefficient of the building envelope surface and improve the accuracy of heat load calculation.

[0009] Preferably, in the data processing module, running the carbon emission calculation model is specifically used for: The real-time heat transfer coefficient of the building envelope is calculated based on the measured data of indoor and outdoor temperature difference and heat flux density. By combining data on solar radiation illuminance, indoor and outdoor humidity, and wind speed, the hourly heat load through the building envelope is calculated by correcting the surface heat transfer coefficient. Based on the heat load and the local power grid carbon emission factor or district heating carbon emission factor, calculate the operating carbon emission rate and accumulated carbon emission amount corresponding to the building envelope.

[0010] Preferably, in the data processing module, the benchmark comparison model includes theoretical operating carbon emissions under the same climatic conditions when using a traditional enclosure structure, specifically used for: The carbon emissions of the energy-saving and efficiency-enhancing building envelope are dynamically compared with the benchmark value in real time to generate real-time carbon emissions and energy-saving ratio. By continuously monitoring changes in heat flux density, abnormal increases in carbon emissions caused by the degradation of the building envelope performance can be identified, and maintenance warnings can be triggered.

[0011] Preferably, in the data processing module, by continuously monitoring changes in heat flux density, an abnormal increase in carbon emissions caused by the performance degradation of the building envelope is identified, and a maintenance warning is triggered. When the heat flux density is continuously monitored to exceed the threshold and the duration exceeds the preset value, it is determined that the building envelope has performance degradation. Maintenance warning information is sent through the communication module, the abnormal part of the building envelope is located, and the corresponding thermal performance optimization scheme is output.

[0012] Preferably, the touch screen is electrically connected to the data processing module for real-time display: Real-time carbon emission rate, daily cumulative carbon emissions, and emission reductions compared to the baseline; Heat transfer coefficient, heat flux density, and indoor and outdoor temperature parameters of the building envelope; Historical trend curves of carbon emission data, monthly / annual carbon emission statistical reports; Early warning information on the performance degradation of the building envelope.

When a sensor failure, communication interruption, or power supply abnormality occurs, it triggers an audible and visual alarm and records the fault information.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention, by embedding sensors in individual building envelope components such as curtain wall panels, roof areas, and composite wall panels, can directly and accurately attribute carbon emissions to specific building envelope components, clearly identify high-carbon emission weak links, provide quantitative data support for energy-saving renovations and low-carbon operation and maintenance, and solve the pain point that traditional monitoring cannot locate the source of carbon emissions. By continuously monitoring changes in heat flux density, performance degradation issues such as decreased air tightness due to aging of the sealing strips of the building envelope and increased solar heat gain due to failure of the reflective coating can be identified in a timely manner. When the carbon emission rate rises abnormally, maintenance warnings are automatically triggered to avoid the increase of hidden carbon emissions due to the deterioration of the building envelope performance and to extend the energy-saving service life of the building envelope. Through the built-in benchmark comparison model of traditional building envelope, the dynamic carbon emission reduction of the energy-saving and efficiency-enhancing building envelope compared with the traditional building envelope can be calculated and displayed in real time. The generated standardized data can be directly used in scenarios such as green building certification, carbon trading emission reduction verification, and low-carbon operation and maintenance effectiveness evaluation. At the same time, the touch screen can intuitively display the emission reduction effect and is also suitable for low-carbon building science popularization and display scenarios.
