Description

Technical Field

[0001] The invention relates to a building energy-saving technology, in particular to a bionic cactus building energy-saving multi-rib structure. Background Art

[0002] At present, the natural lighting design of buildings can effectively reduce the building’s dependence on artificial lighting and heating systems, thereby achieving the effect of energy conservation and emission reduction.

[0003] Today's lighting design technologies are mostly focused on optimizing architectural details, such as the light transmittance design of building surface materials, the guidance of light by building structures, and the maximum capture of natural light by building interior space layouts. These technologies often ignore the lighting and energy-saving potential from the perspective of macro-architectural form, and the issue of energy-saving effects based on the architectural form itself has received less attention.

[0004] Patent CN106285155A proposes a bionic tree tower design that is not only easy to maintain, but also has good stability and reliability, demonstrating the application of bionics in the field of architecture;

[0005] CN102758558A uses a bionic honeycomb ring-shaped building group to allow residents to escape from a fire scene more safely, saving the time people usually spend going up and down the same floors;

[0006] CN107829517B Building exterior wall tiles based on leaf bionic structure alleviate smog. Although there have been many innovations in bionic building technology, there is still a lack of technical innovation in using the cactus bionic principle to enhance building lighting and energy saving effects.

[0007] There are significant differences in the demand for daylighting in buildings in different regions and seasons. In winter, the solar altitude angle is low, the angle of sunlight is small, and the sunshine time is short. Due to unreasonable architectural design, some point-type and plate-type buildings cannot obtain enough natural light, resulting in insufficient indoor temperature and brightness. Artificial lighting must be added, which consumes a lot of energy. In summer, the solar altitude angle is high, the angle of sunlight is large, and the sunshine time is long. Some point-type and plate-type buildings receive too much natural light, resulting in high indoor temperature and brightness. Additional artificial refrigeration and shading measures are required, which increases energy consumption. People spend a long time indoors and have a higher demand for daylighting. In summer, due to the high temperature and low comfort level, people will use more equipment such as air conditioners to adjust the indoor temperature. Direct sunlight in the hot summer will cause the temperature inside the building to rise sharply, which will increase the air conditioning load. Therefore, it is necessary to increase the temperature control device of the building's outer enclosure or building skin.

[0008] Some common plate-type or point-type buildings often have the following disadvantages:

[0009] 1. The building form does not provide direct shading effect;

[0010] 2. Unable to freely adjust the amount of light according to the season;

[0011] 3. Lack of external sunshade facilities on the building.

[0012] In view of this, the present invention is proposed. Summary of the invention

[0013] The purpose of the present invention is to provide a bionic cactus building energy-saving multi-rib structure to solve the above-mentioned technical problems existing in the prior art.

[0014] The objective of the present invention is achieved through the following technical solutions:

[0015] The bionic cactus building energy-saving multi-rib structure of the present invention has a whole structure that is a bionic cactus building structure, including a stem, and ribs are arranged on the side of the stem;

[0016] The stem portion is equivalent to the stem of a cactus, and a stem space is provided inside the stem portion;

[0017] The ribs are equivalent to the ribs of a cactus, and rib spaces are provided inside the ribs.

[0018] Compared with the prior art, the bionic cactus building energy-saving multi-rib structure provided by the present invention can survive in the desert through the study of the multi-rib structure of the cactus. The ribs of the cactus play a vital role. The protruding parts can block part of the direct light and reduce water evaporation. At the same time, the inclined surface of the building surface is designed according to the form of the cactus ribs. This design method can effectively block sunlight, and dispersed solar panels are set on the building surface to reduce the temperature of the building surface and play an energy-saving role.

[0046] In summary, the bionic cactus building energy-saving multi-rib structure of the embodiment of the present invention can be seen. Through the study of the multi-rib structure of the cactus, the cactus can survive in the desert. The ribs of the cactus play a vital role. The protruding part can block part of the direct light and reduce water evaporation. At the same time, the inclined surface of the building surface is designed according to the form of the cactus ribs. This design method can effectively block sunlight, and dispersed solar panels are set on the building surface to reduce the temperature of the building surface and play an energy-saving role.

[0047] The present invention proposes an innovative method of integrating sunshade panels with cactus multi-rib structure buildings by imitating the characteristics, shape and arrangement order of cacti. This method enables the generated building components to be digitally and modularly designed, realizing the BIM construction mode of prefabrication in the factory and assembly on site, and provides new ideas and solutions for the development of green building technology. This method has broad application prospects and market value, and is expected to make important contributions to the sustainable development of the construction industry.

[0048] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the embodiments of the present invention are described in detail with specific embodiments below.

[0049] Embodiment 1:

[0050] As shown in Figure 1 to Figure 8 As shown:

[0051] A design method for a customizable green building with a special form of integrated sunshade. The invention adopts the principle of plant bionics, imitates the multi-rib structure of cactus to generate a climate-adaptive building form, and achieves efficient sunshade and heat management. Compared with traditional buildings, buildings using this design method can reduce solar radiation heat absorption by 27% in summer, and reduce energy consumption by 25% compared with similar buildings, effectively reducing indoor temperature fluctuations and improving living and working comfort.

[0052] The details are as follows:

[0053] 1. The bionic principles and technological prototypes of cactus.

[0054] As a unique plant, the survival strategy and morphological structure of cactus contain rich bionic principles. Cactus usually has a cylindrical or prismatic stem composed of multiple vertically arranged ribs. These ribs form obvious longitudinal stripes on the outer surface, which not only gives the cactus a unique appearance, but also is an exquisite design for its adaptation to extreme environments. The changes in the number and length of cactus ribs under different climatic conditions reflect its growth strategy for adapting to the environment. In hot and arid areas, cacti form an efficient shading mechanism by increasing the number of ribs and extending the rib height. The rib-like structure can block direct sunlight and reduce solar radiation on the surface of the stem, thereby lowering the body temperature and reducing water evaporation. At the same time, the shaded area between the ribs provides a cool microenvironment for the cactus, helping it survive in extreme high temperatures.

[0055] Based on this light regulation strategy, we proposed an innovative architectural design technique, which draws on the appearance characteristics of cacti in the design of architectural form ( Figure 1a , Figure 1b ), forming a unique rib-like structure ( Figure 2) to block direct sunlight, ( Figure 3 ), when exposed to direct sunlight, this form will produce light-receiving areas and backlight areas, thereby reducing the solar radiation received by the building surface and improving the building's shading performance and energy efficiency.

[0056] 2. Formula basis

[0057] In nature, the ratio of the rib height H to the inner radius r of the cross section of a cactus is usually 0.14, and the number of ribs varies from 10 to 30 depending on the plant species and size. The ribs of a cactus can be considered as two right triangles back to back ( Figure 4 The cross-sectional area of ​​a cactus can be considered as the sum of the area of ​​the inner circle and the areas of several right triangles (although there is some overlap between the triangles and the circle, the impact is small and therefore can be ignored here).

[0058] The present invention defines key parameters, including the inner radius r of the cross section, the outer radius R of the cross section, the rib height H, H=Rr, the number of ribs N, and the rib width B, wherein the rib width B can be calculated by B≈2πr / N. The area S of the cactus morphological cross section can be expressed by the following formula:

[0059]

[0060] Since ribs are usually designed to be equal in width and length, the formula can be simplified to:

[0061]

[0062] Among them, πr2 represents the area of ​​the inner circle, represents the sum of the areas of all ribs. Further let H = xr and substitute it into the above formula to obtain:

[0063] S=πr 2 (x+1)(Formula 3)

[0064] When the cactus has the same cross-sectional area (same volume), the ratio of H / r (i.e. the ratio of rib height to inner radius) is a constant, which means that the shading efficiency and stability are maximized while maintaining the same volume. The relationship between r and H can be obtained as:

[0065]

[0066] The present invention defines the shading efficiency η as the ratio of the area of ​​the building surface shaded by its own ribs to the total side area of ​​the building. It can be expressed by the following formula:

[0067]

[0068] in, is the latitude of the current region. Substitute formula 4, x = H / r, and set k = Π / N to obtain:

[0069]

[0070] Taking the derivative of η with respect to x and setting the derivative to zero, the optimal result is:

[0071]

[0072] Combined with formula 3, we can get the rib depth H and latitude Relationship:

[0073]

[0074] Rib number N and latitude Relationship:

[0075]

[0076] 3. Requirements and characteristics of the area of ​​use

[0077] The present invention is particularly suitable for areas with hot and strong sunshine climate characteristics, including but not limited to typical desert climate zones, tropical and subtropical parts. In these geographical environments, due to extreme climatic conditions, the optimization design of architectural form is of great significance for achieving energy conservation and emission reduction and improving indoor living comfort. The target application area of ​​the present invention has an annual average temperature higher than 25°C, long sunshine time, and high annual radiation. Especially in summer, the intensity of direct sunlight is extremely high, which poses a severe challenge to the heat load of buildings. In such a climate, buildings need to have efficient thermal insulation performance to reduce unnecessary solar radiation heat absorption; at the same time, natural ventilation should be promoted, and the ambient temperature difference should be used to achieve passive cooling and reduce air conditioning energy consumption. By adjusting the number, length and distribution of ribs, direct sunlight entering the interior of the building can be significantly reduced. At the same time, the shadow area between the ribs is used to form a natural ventilation duct to enhance the natural cooling effect of the building.

[0078] After precise calculation, the number of ribs per square meter of building surface area is set to n±10% (n is the optimal number based on calculation results and simulation) to ensure that appropriate shading effects can be provided in different seasons and time periods. The rib height H is optimized based on the incident angle θ of the highest point of the local sun in summer, using the formula H=H_opt±5%*tan(θ) (H_opt is the theoretical optimal height). This design can effectively block direct sunlight and avoid excessive blocking of natural light, maintaining sufficient indoor lighting. Based on actual climate data (such as meteorological records of representative locations such as the tropical region of Hainan, China), simulation analysis was performed using numerical simulation software. The results show that compared with traditional designs, the indoor temperature of buildings using the present invention can be reduced by about 3-5°C in summer, and the air conditioning energy consumption can be reduced by about 20%-30%. At the same time, the natural ventilation efficiency is increased by about 40%, significantly improving the living comfort.

[0079] 4. Application and technology of point-type building monomers

[0080] Point-type buildings often adopt a more centralized building layout, with a more centralized exterior outline. While occupying a smaller ground area, the building develops vertically. However, its compact layout often leads to insufficient internal lighting and high external surface temperature. Figure 5 ) For this type of point-type building monomer, we innovatively draw on the natural wisdom of the multi-rib structure of the cactus, accurately calculate the layout and size of the ribs, and use BIM (Building Information Modeling) technology for three-dimensional modeling and simulation analysis to ensure that each rib can maximize its shading effect while maintaining the aesthetics of the building. The technical means provided by the present invention can simulate the best architectural form effect, increase the uniformity of indoor light and suitable temperature in the hot summer, and give equal importance to beauty and functionality, thereby improving the overall quality of the building.

[0081] Embodiment 2:

[0082] Application and technology of panel building monomers

[0083] Plate-type buildings usually adopt a more extended architectural layout. Its characteristic is that the length of the building is much greater than the width, forming a plane shape similar to a "plate". Figure 6 ) The layout of the slab building makes the temperature of the south-facing outer surface of the building higher when the sun is strong. For the slab building, the ribs of the cactus are arranged along the south side of the building, thereby reducing the surface temperature of the building on the south side.

[0084] Parametric optimization selection technology for rib height of cactus bionic building

[0085] Based on the cactus form, according to the meteorological conditions of the selected area, green building performance simulation technology and parametric design can be used to optimize the building's form to the greatest extent. In order to keep warm in winter and shade in summer, the rib height on the south side is reduced. Considering the aesthetic properties of the form, the rib changes are set to rhythmic changes. By constructing a parametric model, the impact of building form on factors such as sunshine duration and solar radiation is effectively evaluated, and the energy consumption of the building form is simulated to obtain the best selection d. At this time, the ratio of the highest rib height to the inner radius is 0.467, the ratio of the lowest rib height to the inner radius is 0.067, and the ratio of the highest rib height to the lowest rib height is 7( Figure 8 ).

[0086] Sun Visor Design

[0087] In the design of the sunshade system, according to the principle of cactus thorns, sunshades are added to form dynamic sunshade components. Figure 7) uses sensor technology to monitor the light intensity, temperature and other parameters inside and outside the building in real time, and uses mechanical transmission devices and intelligent control systems to accurately adjust the angle and position of the sunshade to ensure that the sunshade system is always in the best working state. This technological breakthrough enables the sunshade system to respond to changes in the position and radiation intensity of the sun in real time. By dynamically adjusting the angle of the sunshade, it effectively reduces the exposure of direct sunlight to the outer surface of the building, thereby reducing indoor temperature fluctuations and improving the energy efficiency of the building.

[0088] Photovoltaic integration

[0089] What is even more innovative is that the present invention organically integrates solar photovoltaic panels and sunshades to create a unique photovoltaic integrated composite structure. The photovoltaic panels are cleverly attached to the sunshades, with a buffer layer (a material with good thermal insulation effect) added in between. While the sunshades provide shade for the building, they also provide an ideal installation platform for the photovoltaic panels. The two complement each other and jointly improve the energy efficiency and environmental performance of the building. In typical hot areas, the annual power generation of photovoltaic integrated buildings designed using the present invention has achieved a significant increase of about 15%-20% compared to traditional installation methods. This innovative design not only achieves energy self-sufficiency, but also injects strong impetus into the sustainable development goals of green buildings, demonstrating the infinite possibilities of perfect integration and mutual promotion between sunshades and photovoltaic panels.

[0090] Material selection

[0091] The load-bearing structure adopts steel structure, reinforced concrete structure, wooden structure, etc.; the exterior wall adopts high-performance thermal insulation board, ceramic fiberboard, glass fiber reinforced cement board, lightweight stone composite board, ecological composite wallboard, etc.; the interior wall adopts gypsum board, cork wallboard, etc.; in the selection of building facade materials, materials with high reflectivity and low thermal conductivity coefficient are selected, such as real stone paint, colorful paint, water-based fluorocarbon paint, high-performance reflective coating, ceramic thin plate, etc.; the windows of the building adopt double-layer hollow glass, Low-E insulating glass, coated glass, laminated glass, etc.; the window frames adopt lightweight, high-strength weather-resistant aluminum plate (low thermal conductivity and strong corrosion resistance), stainless steel window frames, thermal bridge aluminum alloy window frames, wood-plastic composite material window frames, etc.; in promoting photovoltaic building integration (BIPV), single crystal silicon solar cells, high-performance EVA (ethylene-vinyl acetate copolymer) film, high-density polyethylene sunshade net, photovoltaic tiles, etc. are used, which not only realizes the utilization of green energy, but also maintains the harmony and unity of the building appearance.

[0092] Program Overview

[0093] The present invention provides two solutions:

[0094] Option 1 is that the building unit is a cactus multi-rib structure. The building unit as a whole adopts a cactus multi-rib structure, and the photovoltaic panels are directly set on the building surface to form an integrated appearance;

[0095] Plan 2 adds a cactus multi-rib structure shading system on the basis of Plan 1. The sunshade and photovoltaic panels are set on the rib peaks according to the principle of thorns, realizing the dual functions of shading and power generation.

[0096] 1. Significant energy-saving effect: This invention uses the self-shading characteristics of the cactus multi-rib structure and uses digital technology to simulate and accurately calculate the layout and size of the cactus ribs, making the building form more accurate and effectively reducing the amount of solar radiation directly received by the building in summer, thereby reducing the internal temperature of the building and reducing the energy consumption of the air-conditioning system. The experimental results show that the building with the cactus multi-rib structure for sunshade can effectively block part of the direct sunlight due to its self-shading characteristics, reducing the amount of solar radiation received by the south facade to about 750W / m per hour. 2 (The reduction rate is about 25%); the temperature inside the building may be reduced by about 3℃ to 10℃; the energy consumption of the air-conditioning system may be reduced to about 8kWh per hour (the saving rate is about 20%).

[0097] 2. Increase people's living comfort, reduce light and glare, open windows to enhance ventilation, reduce indoor temperature of buildings and increase comfort.

[0098] 3. Enhance the sustainability of buildings: By optimizing the building form through parametric means, the present invention can fully consider the energy efficiency and environmental adaptability of the building at the beginning of the design, laying a solid foundation for the long-term use of the building. At the same time, reducing energy consumption also means reducing greenhouse gas emissions. The air-conditioning system of a building without shading measures needs to consume 10kWh of electricity per hour to maintain indoor comfort. After using the palm multi-rib structure for shading, due to the reduction of indoor temperature and solar radiation, the energy consumption of the air-conditioning system may be reduced to about 8kWh per hour (the saving ratio is about 20%). We can calculate the greenhouse gas emissions reduced per hour: greenhouse gas emissions reduced per hour = electricity saved per hour × greenhouse gas emission factor = 2kWh × 0.5kg CO2e / kWh = 1kg CO2e. Therefore, after using the palm multi-rib structure for shading, the air-conditioning system can reduce greenhouse gas emissions by about 1kg per hour (in terms of CO2e). It helps to cope with the challenges of global climate change and embodies the sustainable development concept of green buildings.

[0099] 4. Improve the innovation of building design: The technical means provided by the present invention can enable the performance of buildings to be evaluated through simulation experiments. This method not only improves the efficiency of design, but also brings more innovative possibilities to the field of architectural design.

[0100] 5. Reduce maintenance costs: Since the shading function is built into the building structure design, there is no need to install additional shading equipment, thus saving material costs and installation costs. At the same time, it reduces dependence on the air conditioning system and reduces long-term operation and maintenance costs.

[0101] 6. Improve solar energy efficiency: The temperature of the solar energy collection surface will affect the solar energy efficiency. Too high a temperature will increase the heat loss (such as dissipation to the environment through thermal radiation, heat conduction, etc.), and will also affect the performance of solar energy conversion materials, thereby reducing the overall efficiency. Therefore, lowering the temperature of the solar energy collection surface is an important means to improve solar energy efficiency. The cactus multi-rib structure of the present invention will reduce the temperature of the rib valley by 5 to 8 degrees Celsius compared to other parts due to its self-shading characteristics, and the solar energy efficiency will be increased by 2% to 4%.

[0102] 7. Realize an efficient construction model under the guidance of BIM: Since the rib angle and length of the present invention can be calculated according to a specific formula, the components of the building can be digitized and modularized, and can be converted into a series of customized non-standard modules. By using these modules, buildings can be pre-manufactured in factories and assembled on construction sites, thus realizing an efficient construction model under the guidance of building information modeling (BIM). This model not only improves the manufacturing accuracy and efficiency of building components, but also significantly shortens the construction period, providing a new solution for the rapid and accurate construction of modern buildings.

[0103] 8. Improve the aesthetics and functionality of the building: The multi-rib structure of the cactus not only has excellent sunshade performance, but its unique shape also gives the building a unique aesthetic value. This design perfectly integrates the sunshade function with the building appearance, which not only meets the energy-saving needs, but also enhances the artistic expression of the building, making the building a beautiful landscape in the city.
