[0024] Microenvironmental characteristics, such as thermal environment, wind environment and light environment, have a significant impact on the living comfort of urban building complexes. At the same time, microenvironment optimization through building complex design can reduce building energy consumption and improve the quality of living space to a certain extent. During the design stage of building complex construction and renovation, it is necessary to optimize the design plan in combination with the microenvironmental characteristics of the building complex. Therefore, it is of great application value to reasonably and scientifically obtain the microenvironmental data of urban building complexes.

[0025] During the construction or optimization of a building complex, different construction plans need to be evaluated to determine the optimal construction plan. By evaluating different building complexes based on the microenvironment data of the building complex, the advantages and disadvantages of different construction plans for the same building complex can be scientifically and accurately determined. In related technologies, the microenvironment data of urban building complexes are mostly obtained based on geographic information data and the professional knowledge of designers, and it is impossible to accurately evaluate the microenvironment before and after the optimization of the building complex, and thus it is impossible to judge the advantages and disadvantages of the building complex optimization plan. It can be seen that the urban building complex microenvironment evaluation method in the related technology has the technical problem of being unable to accurately evaluate the microenvironment before and after the optimization of the urban building complex.

[0026] To at least solve some of the above problems, the following Figure 1-Figure 3 The present invention describes the urban building complex microenvironment assessment method, device, electronic equipment and storage medium.

[0027] The urban building complex microenvironment assessment method of this embodiment can be applied to the scenario of evaluating the microenvironment before and after the optimization of the urban building complex, and then the pros and cons of the optimization plan can be determined based on the microenvironment assessment results before and after the optimization of the urban building complex; the urban building complex microenvironment data generation method of this embodiment can be executed by a server.

[0028] Figure 1 It is a schematic diagram of the process of the urban building complex microenvironment assessment method provided by the present invention, such as Figure 1 As shown, including but not limited to the following steps: Step 101, obtaining geographic information and meteorological data of the building complex, wherein the geographic information is used to determine the solar altitude angle and solar radiation of the building complex in a preset period of time, and the meteorological data includes the average temperature, average wind direction and average wind intensity of the building complex in the preset period of time.

[0029] In this embodiment, the building complex can be a residential area or a community building complex; the preset time period refers to a continuous time period, and the preset time period can be divided according to actual needs. The length of the preset time period can be a quarter, a month, a day or an hour.

[0030] The preset time period can be called a time partition, and a year can be divided into multiple time partitions according to actual needs, for example, each quarter is a time partition (a total of 4 time partitions in the whole year) or each month is a time partition (a total of 12 time partitions in the whole year), but not limited to this; generally, the meteorological conditions in the same time partition are similar, therefore, the average value of various meteorological parameters in the same time partition can be used as the meteorological data of the time partition to participate in subsequent calculations to ensure the scientific nature of the calculation results.

[0031] Geographic information is used to determine the solar altitude angle and solar radiation of the building complex in a preset period of time. The geographic information includes the geographical location of the building complex. The solar altitude angle and solar thermal radiation of the building complex in each period of the year can be calculated based on the geographic information, and then the solar altitude angle and solar radiation of the building complex in the preset period of time can be obtained; meteorological data is used to indicate the average temperature, average wind direction and average wind intensity of the building complex in the preset period of time. The meteorological data includes the average temperature, average wind direction and average wind intensity of the building complex in multiple time zones throughout the year.

[0032] Step 102, obtaining a first building complex data set and a second building complex data set, wherein the first building complex data set is the building complex data set before the building complex is optimized, and the second building complex data set is the building complex data set after the building complex is optimized.

[0033] The building complex dataset is used to represent the building data of the building complex, such as the building height, floor area, building orientation, etc. Based on the building complex data, the corresponding building complex can be replicated and constructed.

[0034] In this embodiment, the first building complex data set and the second building complex data set are respectively the building complex data sets before and after the building complex is optimized. Here, the building complex will be optimized according to the optimization plan; specifically, the building complex is a target community, and the optimization plan may be a later transformation of the target community; the building complex may also be a target building complex under construction, and the optimization plan may be an optimization and transformation of the current construction plan of the target building complex; here, the first building complex data set and the second building complex data set are respectively the building complex data sets before and after the optimization of the same building complex.

[0035] It should be noted that the second building complex dataset can be a virtual building complex dataset based on the first building complex dataset and the optimization plan; the first building complex dataset can be a virtual building complex dataset, or it can be a building complex dataset obtained by actually sampling a certain building complex.

[0036] Step 103, using the first building complex data set and the second building complex data set as the current building complex data set to perform the following steps, to obtain a first initial energy consumption corresponding to the first building complex data set and a second initial energy consumption corresponding to the second building complex data set, and to determine an evaluation result based on the first initial energy consumption and the second initial energy consumption: Step 1031, establishing a solution domain based on geographic information, meteorological data and the current building complex data set, meshing the solution domain with finite elements, and calculating the temperature field distribution and flow field distribution of the current building complex data set by using the finite element method; Step 1032, based on the temperature field distribution, the flow field distribution and the current building complex data set, calculate the initial energy consumption required for the building complex to change the specified temperature.

[0037] A solution domain is established based on geographic information, meteorological data and the current building complex data set. Here, it is necessary to determine the boundary of the solution domain. The boundary of the solution domain is usually determined based on the actual layout of the building complex and the surrounding environment. The geographic information, meteorological data and the current building complex data are integrated into the solution domain to form a three-dimensional model.

[0038] The solution domain is meshed by finite element. Finite element software can be used to mesh the solution domain, and the temperature field distribution and flow field distribution of the current building complex data set are calculated by the finite element method. Specifically, the finite element software is used to calculate and solve the control equations of fluid dynamics and heat transfer. During the calculation process, the software will automatically process the temperature and flow field variables on the grid nodes to obtain the temperature field distribution and flow field distribution of the entire solution domain.

[0039] It should be noted that when performing finite element calculations, denser finite element meshes are needed in areas where the gradient of building structure changes is large or at interfaces where building materials change, while sparser meshes are used in areas where the gradient of building structure changes is small or in areas where building materials remain unchanged, in order to balance the calculation accuracy and model scale.

[0040] Optionally, in this embodiment, there is no limitation on the finite element software, for example, it may be ANSYS, ABAQUS, etc.

[0041] Based on the temperature field distribution, flow field distribution and the current building complex data set, the initial energy consumption required for the building complex to change a specified temperature is calculated; specifically, the initial energy consumption required for cooling or heating the building complex can be calculated based on the temperature field distribution, flow field distribution and the current building complex data set, in combination with factors such as the temperature difference between the inside and outside of the building and the heat conduction area.

[0042] It can be understood that the urban building complex microenvironment assessment method of this embodiment can fully consider the heat exchange and air exchange between the building complex and the external environment, take building energy consumption as the key assessment indicator, comprehensively consider factors and variables of many disciplines such as architecture, meteorology, and materials science, and use the two key physical field distributions of temperature field and flow field to systematically and accurately calculate the initial energy consumption of the building, avoid errors caused by empirical parameters, and have higher credibility; finally, by comparing the initial energy consumption calculated by different building complex design schemes, the impact of the building complex design scheme to be assessed on the microenvironment can be reasonably evaluated. The impact of the new construction or renovation design scheme of the urban building complex on the microenvironment can provide a reference basis for the optimization of the urban building complex morphology.

[0043] Through the embodiments provided by the present application, geographic information and meteorological data of a building complex are obtained, wherein the geographic information is used to determine the solar altitude angle and solar radiation of the building complex in a preset period of time, and the meteorological data include the average temperature, average wind direction and average wind strength of the building complex in the preset period of time; a first building complex data set and a second building complex data set are obtained, wherein the first building complex data set is a building complex data set before the building complex is optimized, and the second building complex data set is a building complex data set after the building complex is optimized; the first building complex data set and the second building complex data set are respectively used as the current building complex data sets to perform the following steps, to obtain a first initial energy consumption corresponding to the first building complex data set and a first initial energy consumption corresponding to the second building complex data set The second initial energy consumption corresponding to the building complex data set is obtained, and the evaluation result is determined based on the first initial energy consumption and the second initial energy consumption: a solution domain is established based on geographic information, meteorological data and the current building complex data set, the solution domain is meshed by finite element, and the temperature field distribution and flow field distribution of the current building complex data set are calculated by the finite element method; based on the temperature field distribution, flow field distribution and the current building complex data set, the initial energy consumption required for the building complex to change the specified temperature is calculated, which can solve the technical problem of the urban building complex microenvironment evaluation method in the related technology that it is impossible to accurately evaluate the microenvironment of the urban building complex before and after optimization, thereby improving the evaluation efficiency of the urban building complex microenvironment evaluation method.

[0044] As an optional solution, the evaluation result is determined based on the first initial energy consumption and the second initial energy consumption, including: S11, determining an evaluation result based on a magnitude relationship between the first initial energy consumption and the second initial energy consumption.

[0045] Optionally, determining the evaluation result based on the magnitude relationship between the first initial energy consumption and the second initial energy consumption includes: S21, when the first initial energy consumption is greater than the second initial energy consumption, determining the second building complex data set as the optimal solution; S22: when the first initial energy consumption is less than the second initial energy consumption, determining the first building complex data set as the optimal solution.

[0046] When the first initial energy consumption is greater than the second initial energy consumption, it means that the energy consumption loss of the building complex design scheme corresponding to the second building complex data set is lower, and its design scheme is better, so the second building complex data set is determined as the optimal scheme; when the first initial energy consumption is less than the second initial energy consumption, it means that the energy consumption loss of the building complex design scheme corresponding to the first building complex data set is lower, and its design scheme is better, so the first building complex data set is determined as the optimal scheme.

[0047] Through this embodiment, the evaluation result is determined by comparing the first initial energy consumption with the second initial energy consumption, which can effectively increase the accuracy of determining the evaluation result.

[0048] As an optional solution, a solution domain is established based on geographic information, meteorological data and the current building complex data set, the solution domain is meshed by finite element method, and the temperature field distribution and flow field distribution of the current building complex data set are calculated by finite element method, including: S31, establishing a solution domain based on geographic information, meteorological data and current building complex dataset; S32, constructing a finite element calculation space based on the solution domain, wherein the finite element calculation space includes the building complex and the external environment, and the external environment is an infinite constant temperature heat source and a uniform flow field constructed based on meteorological data; S33, calculating the temperature field distribution and the flow field distribution by using the finite element method based on the initial evaluation parameters and the finite element calculation space.

[0049] In this embodiment, based on geographic information, meteorological data and the current building complex data set, a corresponding solution domain is established, and the external environment is set to an infinite constant temperature heat source and an infinite constant temperature uniform flow field; the meteorological data of each preset time period is used as the external environment parameters, and the temperature field distribution and flow field distribution of the building complex are calculated by the finite element method.

[0050] Optionally, a buffer zone is provided between the building complex and the external environment, and the range of the buffer zone extends outward by 20% to 50% from the range of the building complex.

[0051] Optionally, the initial evaluation parameters include at least: thermal conductivity of building materials and thermal conductivity of air.

[0052] Optionally, the initial evaluation parameters may also include the thermal conductivity of water.

[0053] For example, heat conduction between the building surface and the atmosphere satisfies the relationship: ,in, Represents the conduction heat between the building surface and the atmosphere. represents the temperature difference, represents the thermal conductivity, represents the heat transfer area, Represents the thickness of the heat transfer layer.

[0054] Furthermore, heat conduction occurs between the surface of the building complex and the atmospheric environment, satisfying the relationship: ,in, Represents the conduction heat between the surface of the building complex and the atmospheric environment. represents the temperature difference, represents the thermal conductivity, represents the heat transfer area, Represents the thickness of the heat transfer layer.

[0055] Furthermore, the flow field represented by the wind field conducts heat convection with the building complex, satisfying the relationship: ,in, represents the convective heat between the flow field and the building complex, represents the convection coefficient, represents the convection area, Represents the temperature difference due to convection.

[0056] It should be noted that the above-mentioned relevant data are obtained based on geographic information, meteorological data, current building complex datasets and initial assessment parameters.

[0057] Through this embodiment, the temperature field distribution and the flow field distribution are calculated by the finite element method based on the initial evaluation parameters and the finite element calculation space, which can effectively improve the accuracy of the obtained temperature field distribution and the flow field distribution.
