Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a construction method and a working method of a green building. Background Art

[0002] As global climate change and resource shortage issues become increasingly serious, green buildings, as an important part of sustainable development strategies, have received widespread attention. Traditional construction methods are often accompanied by problems such as high energy consumption, high emissions and resource waste, while green buildings emphasize harmonious coexistence with nature and reduce the negative impact of buildings on the environment through scientific planning and design. However, the current green building construction methods on the market mostly focus on the application of a single technology or material, lacking a systematic solution. Summary of the invention

[0003] The purpose of the present invention is to provide a green building construction method to solve the above problems, comprehensively apply a variety of green technologies and strategies, optimize the entire chain from planning and design, material selection, construction to operation and maintenance, so as to achieve green, energy-saving, intelligent and sustainable buildings.

[0004] Technical solution: The present invention provides a method for constructing a green building, comprising the following steps: Step S1: Prefabricated production and assembly of building components Prefabricated box buildings are used, modular design is carried out according to building needs and functional requirements, high-efficiency and energy-saving green materials are used in component factories, each module is prefabricated, and the prefabricated modules are transported (such as load-carrying platform trailers, waterways or railways), and then hoisted and assembled after being transported to the site, and pipelines are connected at the same time; Step S2: Passive energy-saving design Before assembling in step S1, design the building layout and orientation. Set the building orientation according to the sun angle to ensure that the main use space of the south-facing rooms in the building receives sufficient sunlight, increase the indoor temperature in winter, and avoid large-scale sunlight exposure in the east- and west-facing rooms to prevent indoor overheating in summer. Combined with the local wind environment characteristics, conduct ventilation design to ensure that the building can form a good through-hall wind in summer, and set sunshade components on the windows, and adopt thermal insulation design for the wall panels; Step S3: Active energy-saving design After the building is assembled, solar energy, wind energy and rainwater will be used to install solar photovoltaic panels on the roof of the building, wind power generation piles will be set up outside the building, and renewable energy systems will be used to provide green energy for the building. Solar water heaters will be used to supply hot water, and rainwater collection devices and wastewater recycling devices will be set up to reduce water consumption and sewage discharge. S4: Intelligent Building Management System (BMS) In terms of system management, BMS is used in conjunction with the renewable energy system to monitor the power generation of solar photovoltaic panels and wind power stations, and automatically adjust the energy usage inside the building according to the actual energy supply situation inside the building to ensure a balance between supply and demand. In conjunction with energy-saving equipment, energy-saving doors and windows and high-efficiency energy-saving electrical equipment are used in the building. BMS accurately controls such equipment to optimize energy efficiency.

[0005] Furthermore, in the above-mentioned green building construction method, in step S1, the box building is designed using BIM (Building Information Modeling) technology for digital design, simulating the performance of the building in different environments, optimizing the building orientation, shape coefficient, shading design, etc. to reduce energy consumption, and giving priority to renewable, recyclable or low-environmental-impact building materials in production. During the construction phase, construction personnel are assisted in construction management to ensure construction quality and progress and reduce material waste and rework.

[0006] Furthermore, in the above-mentioned green building construction method, in step S2, the wall panels adopt a thermal insulation design, the insulation panels adopt vacuum insulation panels, the interior of the panels are filled with rock wool and glass wool, the walls adopt polyurethane insulation panels or phenolic insulation panels, and green plants are planted on the exterior walls to form green walls.

[0007] Furthermore, in the above-mentioned green building construction method, in step S3, the foundation piles of the wind power piles adopt a hollow open structure. During installation, a pit is dug, and after the foundation piles are placed, soil is filled into the central opening of the foundation piles, and the soil is compacted to ensure the stress resistance capacity and facilitate dismantling. Only the soil needs to be dug out, and the foundation pile structure does not need to be destroyed and can be reused, so that no construction waste is generated and it is environmentally friendly.

[0008] Furthermore, in the above-mentioned green building construction method, in step S3, the rainwater collection device is connected to the non-drinking water equipment in the building through a pipeline, and cooperates with the BMS to monitor the rainwater volume, water quality and operating status of each facility in real time, thereby realizing the automation and efficiency of rainwater collection and utilization, and further improving the operating efficiency and reliability of the system.

[0009] Furthermore, in the above-mentioned green building construction method, in step S2, green plants are planted on the outer wall to form a green wall, and green plant planting boxes are arranged on the inner and outer sides of the wall panels of the green wall. The green plant planting box is divided into a plurality of grids, and green potted plants are placed in each grid. In step S3, the rainwater collection device is connected to the green plant planting box through a pipe, and the watering work is automatically performed under the control of the BMS.

[0010] Furthermore, in the above-mentioned green building construction method, the prefabricated box building adopted in step S1 is of assembled design, and the prefabricated wall panels, prefabricated floor panels, columns, and connecting parts are prefabricated in the factory. After being transported to the construction site, the various components are fixedly connected by fixing bolts to assemble into box building modules, and then the modules are assembled to complete the overall building of the house.

[0011] Furthermore, in the above-mentioned green building construction method, in step S4, the intelligent building management system (BMS) is combined with the introduction of AI and Internet of Things technologies to improve the real-time monitoring and optimization of the construction process, thereby ensuring the construction quality and progress.

[0012] Furthermore, in the above-mentioned green building construction method, in step S1, prefabricated wall panels, prefabricated floor slabs, columns, and connecting parts are prefabricated in a factory, and the above-mentioned prefabricated components are standardized in design and mass-produced, thereby reducing production costs and increasing production speed. The modular and standardized design can be assembled according to user needs, thereby increasing building flexibility and variability.

[0013] It can be seen from the above technical scheme that the present invention has the following beneficial effects: a green building construction method described in the present invention uses box buildings to modularize the entire building. After prefabrication in the factory, it is transported to the construction site for installation. No on-site wet work is required, and only bolts are used to fix the connection, which reduces the construction process, shortens the construction period, has low cost, and has little impact on the environment. It uses solar and wind energy to generate electricity, uses rainwater to reduce the use of non-drinking water, saves energy, is pollution-free, and manages house equipment through BMS, optimizes resource utilization efficiency, reduces resource consumption, promotes resource recycling, and effectively reduces the impact of buildings on the environment, providing strong support for the sustainable development of the construction industry.
