Description

Technical Field

[0002] Construction engineering refers to the engineering entity formed by the construction of various housing buildings and their affiliated facilities and the installation of pipelines and equipment supporting them. Among them, "housing building" refers to a project with a roof, beams, columns, walls, foundation, and capable of forming an internal space to meet the needs of people's production, residence, study, and public activities. In the traditional construction process, construction engineering cannot be carried out in an energy-efficient and green manner, which increases the construction time and cost.

[0003] In the prior art, a patent with the publication number CN117988556A discloses a construction method for an energy-efficient and green building project, including the following steps: S1.

Store water: Build a rainwater collection device and a sewage treatment device within the construction scope. Beneficial effects: Through the outer sound insulation boards, the construction noise can be reduced by double layers, thereby reducing the noise harassment and noise pollution to residents, and classifying and recycling the wastewater generated during building construction. At the same time, part of the wastewater is recycled at different levels, and the recycled wastewater is used for spraying and dust reduction or washing the wheels of transport vehicles according to different treatment levels, which is beneficial to reducing wastewater pollution during the building construction process. At the same time, the classified treatment and hierarchical use are adopted to standardize the use of wastewater, and reduce the pollution caused by transport vehicles bringing construction soil onto the road.

[0004] The prior art has the following disadvantages: It is not convenient to dynamically adjust the building construction design plan during the construction process, with poor flexibility, slow speed of collecting green environmental protection data, inconvenient for subsequent operation management and maintenance, and not convenient to provide maintenance and other work for the owners after the building construction is completed.

[0005] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of implication that this information constitutes the prior art already known to those of ordinary skill in the art.

Detailed implementation manners

[0014] In order to make the content of the present invention more clearly understood, the technical solutions in the embodiments of the present invention are described clearly and completely.

[0015] Embodiment 1: A construction method for an energy-efficient and green building project, comprising the following steps: Step 1: Establish a three-dimensional model of building information according to BIM technology to generate an optimized design plan; Ecotect can be used to analyze climate characteristics, conduct systematic foundation surveys, and formulate energy-saving strategies based on climate characteristics.

[0016] Regarding the ventilation problem and winter heating, use the Ecotect enthalpy-humidity diagram to analyze the winter and summer temperatures. The highest temperature is in July and the lowest temperature is in January. Utilize the seasonal volatility in summer to select the optimal building size and winter heating method, and while saving internal energy in winter, maximize the use of the internal effect in winter to achieve internal insulation. Adopt natural ventilation, natural light, and solar energy for warming.

[0017] Before determining the layout of the building, first evaluate the optimal orientation of the building according to Ecotect. After analyzing the solar irradiation, determine the spacing between each building so that the daylighting of each building matches the solar irradiation.

[0018] Exterior wall design, the wall structure is: 10 mm cement + 110 mm block + 10 mm cement plaster, with a U-value of 2.62. The wall structure is a double-layer structure of 25 mm pine fiber + 75 mm insulation layer + 10 mm cement mortar, with a U-value of 0.40. The peripheral structure with a high specific heat capacity can save more energy in the building than a small structure with a low heat capacity, and is easier to heat in winter than a large heating plant. In summer, the role of the insulation material makes the room more comfortable and the indoor environment better as a living environment.

[0019] BIM technology is used to analyze the regional climate of the construction area, to create models for prefabricated components, to accurately control the size, materials, and connection methods of prefabricated components, and to determine the amount of building materials used, including steel, wood, cement, and glass. Using recycled steel instead of traditional steel can reduce energy consumption and carbon emissions in the mining and smelting of iron ore; using locally produced building materials can reduce energy consumption and environmental pollution during transportation; at the same time, by rationally optimizing the building structure and component design, the amount of materials used can be accurately controlled to avoid material waste, achieve material conservation goals, reduce construction costs, and improve the economic and environmental benefits of buildings.

[0020] Step 2: Based on step 1, establish a soundproof enclosure, and set up a soundproof enclosure outside the construction area according to the architectural drawings; Step 3. Based on Step 1, establish a water treatment circulation device in the construction area, including rainwater collection and filtration equipment, construction wastewater treatment equipment, dust reduction spray equipment and related water resource transmission pipelines; treat the construction soil to protect the soil from soil erosion, and promptly treat sewage and construction waste to avoid soil pollution; and classify water resources, including mixing water, maintenance water, and sewage, and treat and recycle them in a graded manner.

[0021] Step 4: Based on step 1, excavate a foundation pit in the construction area, use dust reduction spraying equipment to reduce dust in the excavation area, and set up dust nets in areas where no construction is being carried out; collect specific data information on dust, and use vacuum cleaners to control dust in areas with severe dust.

[0022] Step 5: Carry out extrusion structure construction inside the foundation pit, including formwork installation, concrete pouring and foundation backfilling; Step six, selection of building materials and installation of building doors and windows; choose fixed windows as the window type, the window frame material is thermal-insulated aluminum, the thermal-insulated aluminum energy-saving window frame material has significant energy-saving effect, the sealing material selected for the window is polyurethane foam, the window glass adopts multi-layer glass with a hollow structure, solar photovoltaic components are used to achieve lighting function, solar air collectors are used to regulate the air, and additional walls are added to the exterior walls to achieve insulation effect, circulating water pump heating technology is used, and a recycled water source pool system is set up.

[0023] The water source pool system allows rainwater to gradually infiltrate the reused water source pool, merge into groundwater, block the drainage ditch, and then discharge the water directly into the sewage sedimentation tank. Through effective methods such as system operation, it is then discharged into the reused water source pool, strictly controlling sewage discharge and reuse efficiency, which not only ensures the effective implementation of energy conservation and environmental protection, but also improves the utilization efficiency of water resources and achieves the purpose of continuous heating. The use of circulating pump heating technology can not only improve indoor heating efficiency and improve the quality of heating supply, but also further realize the efficient use of thermal energy and reduce water resource waste as much as possible, such as during construction.

[0024] Build a constant temperature system inside the building. Lay capillary tube networks on the concrete floor slabs. Inject cold water into the networks in summer to achieve a cooling effect, and inject hot water into the networks in winter to provide heating. It mainly utilizes the principle of thermal radiation to reduce the overall energy consumption of the building and provide a more comfortable living environment for people.

[0025] Build a full-displacement fresh air system, which can provide fresh air for the indoor space of the building 24 hours a day. The full-displacement fresh air system has low energy consumption, high operating efficiency, and stable humidity. Installing the fresh air system on the ground can also improve the oxygen content in the ground, avoid turbulent flow and eddy current, reduce the disturbance to the indoor air, improve the indoor air quality, and discharge the polluted air in time.

[0026] Step Seven: Detect the indoor environmental quality of the building.

[0027] In the BIM model, combined with the data of indoor environmental monitoring sensors, such as indicators like temperature, humidity, air quality (including CO2 concentration, formaldehyde content, PM2.5, etc.), and noise, the distribution of the indoor environmental quality can be visually displayed. The operation and maintenance personnel can adjust the operation parameters of systems such as air conditioners, ventilation, and fresh air in a timely manner according to the monitoring results to maintain the comfort and health of the indoor environment.

[0028] When the indoor CO2 concentration is too high, automatically increase the fresh air volume; when the indoor temperature is too high or too low, automatically adjust the cooling or heating power of the air conditioning system.

[0029] The above describes the present invention and its implementation manners, and such description is not restrictive. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
