Description

Technical Field

[0001] The present invention relates to the technical field of intelligent building planning and design, and in particular to an intelligent optimization design method and device for a building site for reducing heat island intensity. Background Art

[0002] Modern construction sites provide many functions, such as lighting, air conditioning, elevators, etc., which makes the construction sites prone to heat island effect, affecting the comfort of human life. For example, in large aviation hub buildings, since they have to meet various needs of aviation traffic functions, large aviation hubs often have a series of characteristics such as large aircraft emissions of greenhouse gases, huge airside hardened aprons, high proportion of impermeable ground area, and building area far exceeding that of general public buildings, which produces a more obvious heat island effect.

[0003] The intensity of a building's outdoor heat island is an important indicator for evaluating the building's outdoor thermal environment. It reflects the temperature difference between the building site and the surrounding environment. The intensity of a building's outdoor heat island can be calculated according to the provisions of the construction industry standard "Green Performance Calculation Standard for Civil Buildings" JGJ / T 449-2018.

[0004] Relevant research and practice have shown that designing various green spaces in building sites can reduce the greenhouse effect of building sites. However, the existing technology of adding green space to building sites is often achieved through manual operation by designers. This kind of building site optimization design that relies on the personal experience of designers is not able to objectively analyze all design influencing factors, resulting in low reliability of building site optimization design solutions, and thus cannot effectively reduce the greenhouse effect.

[0084] The present invention discloses an intelligent optimization design method and device for building sites for reducing heat island intensity, which can improve the reliability of the generated building site optimization design scheme, thereby effectively reducing the greenhouse effect of the building site. The following are detailed descriptions.

[0085] Embodiment 1

[0086] See also Figure 1 , Figure 1 1 is a flow chart of a method for intelligent optimization design of building sites for reducing heat island intensity disclosed in an embodiment of the present invention. Figure 1 The intelligent optimization design method for reducing heat island intensity of a building site described above can be applied to an intelligent optimization design device for reducing heat island intensity of a building site. The intelligent optimization design device for reducing heat island intensity of a building site can be integrated in a cloud server or a local server, and the embodiments of the present invention are not limited thereto. Figure 1 As shown, the intelligent optimization design method for reducing the intensity of the heat island may include the following operations:

[0087] 101. Obtain a set of environmental data of the area where the building site is located within a preset first time period; and determine a significant heat island intensity area in the building site where the temperature is higher than the temperature of an area in a preset surrounding range based on the building characteristics of the building site and the set of environmental data.

[0088] In the embodiment of the present invention, specifically, the set of environmental data of the construction site within the preset first time period may be the sunlight radiation data, temperature data, humidity data, wind speed data, wind direction data and greenhouse gas concentration data of the area where the construction site is located in the past several years, and the above data show the overall environmental data of the construction site. The architectural features of the construction site are used to represent the morphology and building materials of the buildings in the construction site, and can generally be directly a three-dimensional model of the construction site, or obtained through analysis of the design drawings of the construction site. The architectural features of the construction site are the main factors affecting the temperature change of the construction site. For example, a road surface paved with asphalt will cause a sharp increase in temperature under light exposure. If the ventilation effect of the asphalt-paved road surface is very poor, the temperature of the area will be significantly higher than the temperature of the surrounding area in a short period of time.

[0089] In the embodiment of the present invention, based on the environmental data set and the architectural characteristics of the construction site, it is possible to analyze the impact of the architectural characteristics of the construction site on various environmental data, such as the impact on temperature, the impact on solar radiation, the impact on wind direction, the impact on greenhouse gas concentration, etc., and then determine the area with significant heat island intensity based on this impact, and the temperature of the area with significant heat island intensity is higher than the regional temperature of the preset surrounding range.

[0090] In the embodiment of the present invention, optionally, the following method may be used to determine the area with significant heat island intensity:

[0091] The building site is divided into several sub-areas according to the functional characteristics of the building site or the independent buildings inside, and the average temperature of each sub-area is determined. If the average temperature of a sub-area is higher than the average of the average temperatures of all adjacent sub-areas, and the higher part exceeds a certain range, then the sub-area is determined to be a sub-area with significant heat island intensity.

[0092] 102. For each area with significant heat island intensity, determine the green space characteristics that match the area with significant heat island intensity based on the regional building characteristics of the area with significant heat island intensity.

[0093] In the embodiment of the present invention, the regional building characteristics are used to represent the morphology and building materials of the buildings in the area with significant heat island intensity. Greenland buildings refer to the types of buildings that fully consider the integration, protection and utilization of the natural environment during planning, design, construction and operation. Greenland buildings can well improve the heat island effect in the building site. The embodiment of the present invention determines the greenland characteristics that match the area with significant heat island intensity based on the regional building characteristics of the area with significant heat island intensity. The greenland characteristics are used to represent the morphology and building materials of the greenland buildings that are added in the area with significant heat island intensity to reduce the heat island intensity. Different building parts need to be coordinated with greenland buildings that match them to realize the function of greenland buildings to improve the heat island effect. For example, for roads in the construction site, the heat island intensity can be reduced by planting shrubs and trees. For vertical walls, the heat island intensity can be reduced by setting vertical greening walls.

[0094] 103. Update the building characteristics of the building site according to all green space characteristics to obtain optimized building characteristics of the building site.

[0095] In the embodiment of the present invention, the green space feature is used to represent the morphology and building materials of the green space buildings added in the heat island intensity significant area for reducing the heat island intensity. For example, the green space feature represents setting a garden of a predetermined size at a predetermined location. The building features of the building site are updated according to all the green space features, so as to achieve the optimal design of the building site and obtain the optimized building features of the building site. The optimized building features are used to represent the morphology and building materials of the building after the corresponding green space building is added to the building site.

[0096] 104. Determine the heat island intensity of the building site based on the optimized building features and the environmental data set of the building site, and judge whether the heat island intensity is less than a preset heat island intensity threshold. If it is judged that the heat island intensity is less than the heat island intensity threshold, generate an optimized design plan for the building site based on the optimized building features of the building site.

[0097] In the embodiment of the present invention, the optimized building features represent the morphology and building materials of the building after the optimization design is completed. According to the environmental data set and the optimized building features of the construction site, the influence of the optimized building features of the construction site on various environmental data can be analyzed, such as the influence on temperature, the influence on solar radiation, the influence on wind direction, the influence on greenhouse gas concentration, etc., and the heat island intensity of the construction site can be calculated by combining the environmental data set and the influence of the optimized building features on various environmental data.

[0098] In the embodiment of the present invention, if it is determined that the heat island intensity is less than the heat island intensity threshold, it means that the heat island intensity of the building site is effectively reduced by adding green space buildings in the area with significant heat island intensity in the present invention, and an optimized design plan for the building site is generated according to the optimized building features of the building site.

[0099] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the embodiment of the present invention can determine the areas with significant heat island intensity in the building site, and based on the areas with significant heat island intensity, intelligently and automatically design green buildings that can improve the heat island effect in the areas with significant heat island intensity; and by checking whether the heat island intensity of the building site with the green building added is lower than a preset threshold, it is judged whether the addition of green buildings in the areas with significant heat island intensity has effectively reduced the heat island intensity of the building site, and then intelligently determine the optimization design scheme that effectively reduces the heat island intensity of the building site, so as to improve the reliability of the generated building site optimization design scheme, thereby effectively reducing the greenhouse effect of the building site.

[0100] In an optional embodiment, the method may further include:

[0101] Obtain a three-dimensional model of the building site, and determine the heat island effect-related structure of the building site based on the three-dimensional model of the building site;

[0102] Obtain the thermophysical properties of each part of each heat island effect related structure;

[0103] Determine the architectural characteristics of the building site based on the thermophysical properties of all heat island effect related structures and the individual parts of each heat island effect related structure.

[0104] The architectural features of a construction site are used to represent the morphology and building materials of the buildings in the construction site. If the three-dimensional model of the construction site is directly used as the architectural features of the construction site, the larger the construction site, the greater the amount of calculation, which brings great calculation difficulties to some large construction sites. Therefore, in this optional embodiment, by processing the three-dimensional model of the construction site and combining it with thermal physical properties, the architectural features of the construction site can be determined more efficiently.

[0105] In the embodiment of the present invention, specifically, by analyzing the three-dimensional model of the building site, the heat island effect related structure of the building site can be obtained, wherein the heat island effect related structure includes the three-dimensional structure of the building object in the building site that can affect the climate of the building site. The above operation eliminates the content in the building site that has no effect on the climate of the building site, and the heat island effect related structure can be represented by a series of structural feature matrices constituting the main body of the building site, without using the data of the three-dimensional model, thereby reducing the amount of calculation.

[0106] In the embodiment of the present invention, the thermophysical properties include one or more of reflectivity, thermal conductivity, specific heat capacity, and water permeability. The thermophysical properties are the main indicators for measuring the impact of heat island effect related structures on the environmental data of temperature. Therefore, the thermophysical properties of all heat island effect related structures and each part of each heat island effect related structure can more efficiently represent the morphology and building materials of the buildings in the construction site while reducing the amount of calculation. The architectural features of the construction site can be determined by the thermophysical properties of all heat island effect related structures and each part of each heat island effect related structure.

[0107] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the optional embodiment can be implemented to analyze the three-dimensional model of the building site to obtain the heat island effect related structure of the building site, and use the thermophysical properties of all heat island effect related structures and each part of each heat island effect related structure to more efficiently represent the morphology and building materials of the buildings in the building site while reducing the amount of calculation. This provides more efficient and practical data support for the intelligent optimization design method for building sites for reducing heat island intensity in the embodiment of the present invention, thereby further improving the reliability of the generated building site optimization design scheme.

[0108] In another optional embodiment, the method may further include:

[0109] Acquire a set of regional environmental data of all grid areas within the building site within a preset second time period;

[0110] And, based on the building characteristics and environmental data set of the building site, the specific operation of determining the heat island intensity significant area in the building site where the temperature is higher than the temperature of the area in the preset surrounding range may include:

[0111] Input the building characteristics and environmental data set into the pre-trained heat island analysis model to obtain the target temperature distribution map and target air circulation map output by the heat island analysis model;

[0112] Based on the regional environmental data set, target temperature distribution map and target air circulation map, the areas with significant heat island intensity in the building site are determined.

[0113] In this optional embodiment, the regional environmental data includes the environmental data measurement values ​​of the corresponding grid area, and the grid area includes the area divided by the building site according to the preset grid area division method. For example, the building site can be placed in a 3*3 grid block, and the area in each grid block is a grid area, and the environmental data measurement values ​​of the corresponding grid area are obtained to generate a regional environmental data set. Optionally, the preset second time period can be the past year, and several typical environmental data time periods can be determined based on the environmental data set of the area where the building site is located in the preset first time period, and the full-day time period covering no less than 12 typical meteorological days in different seasons can also be selected.

[0114] In this optional embodiment, the heat island analysis model is obtained using multiple sets of training data sets, each set of training data sets includes building feature-environmental data combination data and standard temperature distribution map data and standard air circulation map data corresponding to the building feature-environmental data combination data, and the heat island analysis model is used to determine the temperature distribution map and the air circulation map based on the building feature and environmental data sets.

[0115] In this optional embodiment, the building characteristics and environmental data set are input into the pre-trained heat island analysis model to obtain the target temperature distribution map and target air circulation map output by the heat island analysis model, wherein the temperature distribution map and the air circulation map can best reflect the heat distribution of the building site, but the accuracy of the temperature distribution map and the air circulation map generated based on the model alone is not enough, and it is also necessary to combine the regional environmental data set obtained by actual measurement within the preset second time period to assist in verification. For example, for a target area whose temperature reflected on the temperature distribution map is higher than that of the surrounding area, if the environmental data measurement value of the grid area where the target area is located is not higher than the environmental data measurement value of the surrounding grid area, then the target area may be judged inaccurately and needs further verification to be determined. Therefore, this optional embodiment determines the heat island intensity significant area in the building site based on the regional environmental data set, the target temperature distribution map and the target air circulation map, thereby improving the accuracy of determining the heat island intensity significant area.

[0116] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the optional embodiment can automatically output temperature distribution maps and air circulation maps for the building sites through the trained heat island analysis model, and then combine the regional environmental data set obtained by actual measurement within the preset second time period, so as to accurately determine the areas with significant heat island intensity in the building site.

[0117] In another optional embodiment, for each heat island intensity significant area, according to the regional building characteristics of the heat island intensity significant area, a specific method of determining the green space characteristics matching the heat island intensity significant area may include:

[0118] For each heat island intensity significant region, determine the regional building characteristics of the heat island intensity significant region based on the regional heat island effect related structures and the thermophysical properties of each part of the regional heat island effect related structures included in the heat island intensity significant region;

[0119] For each area with significant heat island intensity, the modifiable building features in the area with significant heat island intensity are determined according to the regional building features of the area with significant heat island intensity; based on the modifiable building features, green space features matching the area with significant heat island intensity are generated, and the green space features include one or more of green space location parameters, green space shape parameters, green space type parameters, permeable pavement parameters and thermophysical property adjustment parameters.

[0120] In this optional embodiment, the regional heat island effect related structure includes a heat island effect related structure whose overlapping area with the heat island intensity significant area exceeds a preset area threshold. Some heat island effect related structures occupy a large area in the building site, or run through multiple heat island intensity significant areas. For example, a lawn borders the parking area, office area, and energy supply area respectively, but the lawn cannot be divided. In this case, it is necessary to determine whether to regard the lawn, a heat island effect related structure, as a regional heat island effect related structure in the parking area, office area, and energy supply area based on the overlapping area between the lawn and the parking area, office area, and energy supply area.

[0121] In this optional embodiment, the green space characteristics include one or more of green space location parameters, green space shape parameters, green space type parameters, permeable pavement parameters, and thermal physical property adjustment parameters. For example, for a super-large aviation hub with significant heat island intensity, a parameter combination of green space characteristics is designed to indicate the addition of specially designed gardens in conjunction with aviation hubs, by reasonably setting the garden location, controlling the garden space scale, introducing large areas of water and green vegetation, etc.

[0122] In the prior art, the design of adding green space to the building site is often implemented by the designer's manual operation. This building site optimization design that relies on the designer's personal experience is not able to objectively analyze all design influencing factors, resulting in low reliability of the building site optimization design scheme. In this optional embodiment, the green space features that match the heat island intensity significant area are intelligently and automatically generated by determining the modifiable building features, wherein the modifiable building features are used to represent the buildings in the heat island intensity significant area that are allowed to be modified.

[0123] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the optional embodiment can more reasonably and accurately determine the regional building characteristics of the area with significant heat island intensity based on the overlapping area between the area with significant heat island intensity and the structure related to the heat island effect; and through the determined modifiable building characteristics, the green space characteristics matching the area with significant heat island intensity are intelligently and automatically generated, thereby improving the reliability of the generated building site optimization design scheme.

[0124] In yet another optional embodiment, the method may further include:

[0125] If it is determined that the heat island intensity is greater than or equal to the heat island intensity threshold, then the execution is re-triggered to generate green space characteristics matching the heat island intensity significant area for each heat island intensity significant area based on the modifiable building characteristics; the building characteristics of the building site are updated according to all the green space characteristics to obtain the optimized building characteristics of the building site; the heat island intensity of the building site is determined according to the optimized building characteristics of the building site and the environmental data set, and it is determined whether the heat island intensity is less than the preset heat island intensity threshold, until it is determined that the heat island intensity is less than the heat island intensity threshold.

[0126] In this optional embodiment, for green space features that fail to effectively reduce the heat island intensity of the building site, it is necessary to perform iterative operations for optimization design. Since the generation of green space features has a large degree of freedom, for example, a set of green space location parameters, green space shape parameters, green space type parameters, permeable pavement parameters and thermal physical property adjustment parameters can be randomly generated within the range of modifiable building features as initial green space features, and this set of parameters is adjusted in each subsequent iterative operation to ultimately obtain green space features that meet the requirements.

[0127] It can be seen that the intelligent optimization design method for building sites for reducing the intensity of heat islands in the optional embodiment can continuously optimize the green space characteristics in an iterative manner. When the requirements for reducing the intensity of heat islands are very high, the green space characteristics that meet the requirements can be finally determined through a continuous optimization process, thereby improving the reliability of the generated building site optimization design scheme, making the intelligent optimization design method for building sites for reducing the intensity of heat islands of the present invention more applicable to more scenarios.

[0128] In yet another optional embodiment, a specific method of obtaining a set of environmental data of an area where a construction site is located within a preset first time period may include:

[0129] Obtaining environmental data of the area where the building site is located in all consecutive sub-time periods within a preset first time period;

[0130] And, based on the optimized building characteristics and environmental data set of the building site, a specific method for determining the heat island intensity of the building site may include:

[0131] Inputting optimized building characteristics and environmental data in all sub-time periods into the heat island analysis model, obtaining optimized temperature distribution diagrams and optimized air circulation diagrams corresponding to all sub-time periods output by the heat island analysis model;

[0132] The heat island intensity of the building site is determined based on the optimized temperature distribution map and the optimized air circulation map corresponding to all sub-time periods.

[0133] In this optional embodiment, the continuous sub-time periods within the first time period may be each consecutive quarter in the past three years, or each consecutive month in the past year, so as to obtain more representative environmental data. The environmental data at least includes temperature data and wind direction data that directly affect heat distribution, and may also include one or more of humidity data, wind speed data, and greenhouse gas concentration data that can affect heat distribution; the environmental data set includes environmental data in all sub-time periods.

[0134] In this optional embodiment, the intensity of the heat island effect is calculated based on the heat distribution of the building site, wherein the optimized temperature distribution map and the optimized air circulation map can well represent the heat distribution of the building site.

[0135] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the optional embodiment can accurately represent the heat distribution of the building site according to the optimized temperature distribution map and the optimized air circulation map, and combine the environmental data with a wider data range in multiple sub-time periods to generate multiple optimized temperature distribution maps and optimized air circulation maps representing different time periods, so as to more accurately determine the heat island intensity of the building site, thereby providing reliable verification data for the optimization design scheme of the building site, so as to further improve the reliability of the generated optimization design scheme of the building site.

[0136] In yet another optional embodiment, the building site is an airport, and the specific method of generating green space features matching the heat island intensity significant area based on the modifiable building features may include:

[0137] Based on the modifiable building features and the wind direction data in the environmental data, the green space location parameters matching the heat island intensity significant area are generated. The green space location parameters are used to indicate the target location where the green space building to be added is set between the corridor and the main building or inside the main building.

[0138] Based on the modifiable building features, the green space shape parameters matching the heat island intensity significant area are generated, and the green space shape parameters are used to represent the height-width ratio of the green space building to be added;

[0139] Based on the modifiable building features, the green space type parameters matching the heat island intensity significant area are generated. The green space type parameters are used to indicate the proportion of trees or shrubs in the green space buildings to be added.

[0140] Based on the modifiable building features, permeable pavement parameters matching the heat island intensity significant area are generated, and the permeable pavement parameters are used to represent the area of ​​permeable pavement used in the green space building to be added;

[0141] Based on the modifiable building features, thermophysical property adjustment parameters matching the heat island intensity significant area are generated, and the thermophysical property adjustment parameters are used to represent the thermophysical properties of the building structure of the green space building to be added.

[0142] In this optional embodiment, the construction site is an airport. Since airports have to meet various requirements of air traffic functions, they often have a series of characteristics such as large amounts of greenhouse gas emissions from aircraft, huge areas of airside hardened aprons, a high proportion of impermeable ground area, and a building area far exceeding that of general public buildings, resulting in a more obvious heat island effect.

[0143] For an airport, when adding green space buildings, the optional design can be achieved by generating green space location parameters, green space shape parameters, green space type parameters, permeable pavement parameters and thermophysical property adjustment parameters that match the heat island intensity significant area as follows:

[0144] (1) Site selection strategy: The green building is arranged between the corridor and the main building or when the depth of the main building exceeds 150 meters. The specific location needs to be determined in combination with wind direction data. (2) Scale control: The height-to-width ratio of the green building is maintained between 4:1 and 1:1 to form a self-shading effect, reduce direct solar heat gain, and enhance ventilation and heat dissipation. (3) Water bodies and green plants: Ensure that the water body and green plant coverage exceeds 70%, and enhance cooling through ground reflection and water evaporation. The vegetation is mainly tall trees and shrubs, with a shade area of ​​not less than 60%, thereby absorbing carbon dioxide and reducing the greenhouse effect. (4) Vertical greening: At least 30% of the side walls of the green building are vertically greened to reduce the thermal effect caused by multiple reflections of solar radiation and absorb greenhouse gases. (5) Permeable pavement: Use permeable pavement to reduce solar radiation heat gain and increase evaporation cooling effect. (6) High-reflective roof: The buildings in the green building use high-reflective metal roofs to reduce solar radiation heat gain and reduce local greenhouse effect. (7) Spatial transition: Using commercial shops as a transition between green buildings and main process spaces can reduce the impact of the heat island effect on air conditioning energy consumption. (8) High-performance glass: Using glass curtain walls with high thermal performance can reduce the impact of outdoor solar radiation and heat island effect on indoor energy consumption.

[0145] It can be seen that the intelligent optimization design method for building sites for reducing heat island intensity in the optional embodiment is implemented, by generating green space location parameters, green space shape parameters, green space type parameters, permeable paving parameters and thermal physical property adjustment parameters that match the area with significant heat island intensity, to achieve a reasonable design of green space buildings, thereby generating richer and more comprehensive green space characteristics, thereby generating an optimized design scheme for the building site with higher adaptability and reliability.
