Description
Technical Field
[0001] The present invention relates to the technical field of low-carbon building and park design, and in particular to an energy-saving and carbon-reduction optimization method and system for a low-carbon park. Background Art
[0002] In recent years, with the intensification of global climate change issues, the development of low-carbon technologies has gradually become an important direction for sustainable urban development. Many countries and regions have successively introduced technical measures to reduce carbon emissions and promote the use of renewable energy. Against this background, the construction of low-carbon parks has gradually emerged and become an important means to achieve urban environmental friendliness and economic sustainable development. Low-carbon parks are committed to building energy-saving and environmentally friendly living and working environments by optimizing spatial layout, improving energy efficiency and reducing carbon emissions. The development of modern information technology, architectural design theory and environmental science has provided new perspectives and tools for the system design of low-carbon parks and promoted the continuous advancement of related technologies.
[0003] Although the current technologies and methods related to low-carbon parks have made certain progress, there are still many shortcomings. The existing carbon emission quantification models mostly rely on traditional statistical methods, which are difficult to comprehensively and accurately consider a variety of influencing factors, such as traffic patterns and building operation energy consumption. The spatial layout optimization process often lacks a real-time feedback mechanism and cannot effectively integrate the optimal building arrangement and thermal comfort evaluation, resulting in the layout design being unable to achieve the expected low-carbon effect. When identifying and responding to multi-objective optimization problems, the existing technology often focuses on a single goal, ignoring the dual considerations of low carbon and thermal comfort, resulting in limitations in the design scheme, and therefore cannot fully meet the needs of users in different regions. The present invention uses a systematic approach to formulate a detailed carbon emission function, quantify various influencing factors, and introduce virtualization operations and optimization constraint mechanisms, thereby effectively improving the flexibility and comprehensiveness of park design and effectively achieving energy conservation and carbon reduction.

[0030] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.
[0031] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides an energy-saving and carbon-reduction optimization method for a low-carbon park, comprising:
[0032] S1: Develop a carbon emission function and quantify each influencing factor.
[0033] Furthermore, a carbon emission function is formulated and various influencing factors are quantified, including the calculation of CO2 emissions and fuel consumption during transportation. CO2 emissions are calculated and expressed as:
[0034]
[0035] Among them, E1 represents the CO2 emissions generated by each unit of transportation distance, i is the type of transportation fuel, representing different fuel categories, Q represents the fuel consumption of the transportation mode, and C represents the carbon dioxide emission coefficient of the fuel; the fuel consumption is calculated as:
[0036] Q = ∑(K × D)
[0037] Among them, Q represents the consumption of a certain fuel in the transportation mode, K represents the transportation distance of the transportation mode, and D represents the fuel consumption per 100 kilometers of the transportation equipment.
[0038] It should be noted that the formulation of carbon emission functions and the quantification of various influencing factors also include estimating the carbon emissions of buildings through the carbon emission indicators of building heating consumption and building equipment consumption. The carbon emissions during the building operation phase are determined based on the energy consumption of different types of systems and the carbon emission factors of different types of energy. The total carbon emissions per unit building area during the building operation phase are calculated as C M , expressed as:
[0039]
[0040] Among them, C M It represents the net carbon emissions per unit area during the operation phase of a building, and is used to evaluate the annual carbon emissions per unit area of a building. irepresents the carbon emission factor of the i-th energy type, which is used to convert energy consumption into corresponding carbon emissions, C p is the carbon sink obtained from the renewable energy system, which indicates the carbon emission reduced by the building through the use of clean energy. y represents the number of years, which is used to accumulate the total carbon emissions of the building. A represents the total building area, which is used to normalize the carbon emissions to the total carbon emissions calculation formula of the building energy consumption per unit area, which is expressed as:
[0041]
[0042] Where E represents the annual energy consumption of the i-th type of building, E i,j represents the amount of energy consumed by the jth system in the building, ER i,j It represents the amount of the i-th energy consumed by the j-th system that is provided by the renewable energy system.
[0043] It should also be noted that the formulation of a carbon emission function and the quantification of various influencing factors play an important role in energy conservation and carbon reduction in low-carbon parks. Detailed calculations of carbon emissions in the transportation process enable emissions from different fuel types and modes of transportation to be clearly quantified. Mathematical models and formulas are used to calculate emissions per unit transportation distance, enabling scientific assessments of the ecological impacts of various types of transportation. This not only helps identify the most environmentally burdensome modes of transportation, but also lays the foundation for the construction of a low-carbon transportation system within the park. It also provides an important basis for the systematic management of low-carbon parks, enhances the understanding of the overall carbon emission level of the park, and provides support for the formulation of scientific and reasonable carbon reduction targets. When park managers can clearly see the specific contribution of each factor, they can further improve design decisions and implement more efficient management measures, laying a solid foundation for subsequent energy conservation and emission reduction strategies.
[0044] S2: Virtualize the spatial layout of the park and perform multi-objective optimization.
[0045] Furthermore, the virtualization operation of the spatial layout of the park includes writing the site generation and building placement program in Rhino. Based on the actual site size of the park, the corresponding plots are generated as the boundary constraints of the design optimization. The building placement part selects the building type according to the actual survey of the park, and the structure is constructed through three-dimensional data, building area and building floor height to confirm the layout of the building in the specified area, so as to realize the digital migration of the overall planning of the park. By defining the plot size and center point, the dot matrix method is used in Rhino to establish the simulated site area, input the relevant site environment information, confirm that the boundary constraints are followed in the subsequent building placement process, and set the scope of the building block change to be restricted through exhaustive loops in the later optimization. According to the business format of the park, an initial model library of various building types is established, and the number and area range of each building are defined. Through the building placement module, the building and its information attributes are structured as intelligent entities, and the building height, length, width and area and other constraints are set to confirm that there is no overlap or close contact between the buildings. Based on the functional zoning and planning of the park, a random algorithm is used to assign initial positions to various building intelligent entities, and a preliminary building layout is generated through the generated boundaries and constraints.
[0046] It should be noted that the multi-objective optimization includes identifying each building intelligent entity and site information through the low-carbon optimization module, calculating the overall carbon emission value of the park, using the thermal environment optimization module to evaluate the wind environment comfort of the park, and using the multi-objective genetic algorithm of the Numpy and Scipy scientific computing libraries in Python, taking carbon emissions and outdoor thermal comfort as objective functions, performing multiple iterative optimizations, and obtaining the optimal building arrangement and volume.
[0047] It should also be noted that the virtualization of the spatial layout of the park and the multi-objective optimization are aimed at combining digital technology with traditional park design to achieve more efficient and scientific space utilization. The actual site is digitally transformed through 3D modeling software such as Rhino, which can intuitively present the existing space conditions and design requirements. The visualization method not only improves the transparency of the design process, but also enables stakeholders to better participate in the design process. When performing multi-objective optimization, designers use virtual environments to simulate the functions and impacts of different building combinations, thereby achieving comprehensive optimization. Not only the spatial relationship between buildings is considered, but also the overall functional distribution and environmental impact of the park are taken into account, promoting the generation of high-efficiency and low-carbon design solutions. The park has not only become a space to achieve low-carbon goals, but also an intelligent place that applies modern technology and management concepts, thereby improving the overall use effect and social value.
[0048] S3: Establish a low-carbon and thermal comfort evaluation feedback mechanism by optimizing the constraint program.
[0049] Furthermore, the optimization constraint procedure includes calculating the total carbon emissions of the park, involving transportation carbon emissions, building carbon emissions, photovoltaic power generation carbon sinks and green space carbon sinks. Python is used to assign values to each item, with transportation and building carbon emissions as positive values and photovoltaic power generation and green space carbon sinks as negative values. The generated three-dimensional model is then numerically calculated. If the total carbon emissions are greater than zero, the layout model does not meet the carbon reduction requirements, and False is output and the model is regenerated. If the total carbon emissions are less than or equal to zero, it means that the model meets the low-carbon target, True is output, and it is imported into the next optimization step until the optimal solution that meets the low-carbon and thermal comfort requirements is found.
[0050] It should be noted that the establishment of a low-carbon and thermal comfort evaluation feedback mechanism includes connecting the digital park model to the Grasshopper platform after completing the carbon emission verification, using the Butterfly tool in the Ladybug plug-in to simulate the wind environment, and generating grid data, including the wind speed value of each grid point. The number of grids with wind speeds between 1-5m / s is counted by Numpy to obtain the proportion of the park's comfortable area. Combined with the overall planning model of the park, the thermal comfort of the park is evaluated through quantitative data, and relevant data is exported.
[0051] It should also be noted that by quantifying various carbon emission sources in the park, including transportation, construction and greening, a comprehensive evaluation model is formed. On this basis, the optimization constraint program can timely detect whether the design plan meets the low-carbon goals and provide real-time feedback to managers, ensuring the flexibility and scientificity of the park design during implementation. Architects, engineers and planners are encouraged to consider the comprehensive impact of carbon emissions from the beginning of the design. The establishment of a low-carbon and thermal comfort evaluation feedback mechanism has a direct impact on the users of the park. Through the simulation and analysis of environmental parameters such as wind speed and temperature, designers can clearly identify which areas are more suitable for people's living and activities, ensuring the harmonious coexistence of buildings and the natural environment. The iteration and optimization of the park design has also become more efficient, ensuring that in the actual operation process, various services and facilities can be adjusted and improved in a timely manner, so that the park continues to develop towards the goal of lower carbon and more environmentally friendly.
[0052] Example 2 is an embodiment of the present invention, which provides an energy-saving and carbon-reduction optimization method for a low-carbon park. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.
[0053] Firstly, a carbon emission function is designed according to different modes of transportation and building energy consumption in the park. The modes of transportation include public transportation, private cars and walking, and the building energy consumption includes HVAC, lighting and equipment operation. The model is established by collecting energy consumption data of multiple modes of transportation, including different fuel consumption and emission coefficients. During the experiment, it is assumed that the total transportation distance in the park is 10,000 kilometers, and diesel and electric fuels are used to calculate the carbon emissions of various modes of transportation. A park with an area of 10 hectares is selected for virtual modeling, and the program for site generation and building placement is written using Rhino software. Based on the existing planning data, including building type, area and floor height, the boundary conditions of the building are set by the lattice method, and a digital park model is constructed. An initial model library is established, the height, size and functional area of the building are defined, and the spatial layout is optimized. The Numpy and Scipy libraries in Python are used to implement a multi-objective genetic algorithm to calculate the overall carbon emission value of the park, and the thermal comfort of the building at different wind speeds is evaluated. After multiple iterations of optimization, the optimal arrangement and combination of buildings in the park was obtained; after completing the model optimization, the Grasshopper platform was connected, and the Ladybug plug-in was used to simulate the wind environment and evaluate the thermal comfort of the park. The generated grid data provided wind speed information at each location and was quantified into different comfort zone ratios; in summary, the present invention is effective and innovative in energy conservation and carbon reduction, and has practical application value in improving the overall energy efficiency of the park and reducing environmental impact.
