Green fish Company assists Country Garden’s ultra-low energy consumption residential insulation boards to cooperate with full-cycle service

　　1. Project background

　　Policy and market-driven

　　Country Garden responds to the national "dual carbon" strategy and plans to develop the first near-zero energy-consuming residential demonstration project "Country Garden Xingcuiyuan" in Xiongan New Area, Hebei, requiring the exterior wall insulation system to meet the following standards:

　　The thermal conductivity is ≤0.024W/(m·K), reaching the national standard A-level fire protection;

　　Adapt to extreme temperature differences in the north (-15℃ in winter to 38℃ in summer), the performance attenuation rate is <5% during the 30-year service life;

　　Compatible with prefabricated construction technology, it supports dry construction to reduce on-site wet operations.

　　Supplier Filter

　　Country Garden evaluated 12 insulation material companies across the country through public bidding, and Green fish Company was selected with three major advantages:

　　Technical barriers: The independently developed thermal insulation board has both efficient thermal insulation and fire resistance;

　　Full-cycle service: Provides one-stop solutions from design optimization, construction training to post-maintenance.

　　2. Technical solutions and customized innovation

　　Breakthrough in material performance

　　Core structure: The double-layer composite process of "nanoaerogel felt + basalt fiber wool" is adopted, and the thermal conductivity is reduced by 40% compared with traditional rock wool boards;

　　Fire resistance enhancement: By adding inorganic flame retardant, the oxygen index is ≥35%, and passed the GB 8624-2012 A(A2) grade combustion test;

　　Hydrophobic treatment: The surface is coated with a silicone hydrophobic layer, with a water absorption rate of <1%, to avoid hollowing and falling off caused by freeze-thaw cycle in the north.

　　Prefabricated construction adaptation

　　Design of mother-child buckle splicing system: card slots are reserved at the edge of the board, fixed by mechanical choke, and the construction efficiency is 60% higher than that of traditional bonding technology;

　　Supported lightweight anchors: single point load-bearing up to 200kg, meeting the requirements of 8 degrees of seismic fortification intensity.

　　Digital control

　　Implant RFID chips: realize the full process traceability of each board from production to installation;

　　Develop BIM plug-in: Automatically generate insulation layer layout diagrams to reduce material waste by 12%.

　　III. Implementation process and risk control

　　Phone segment verification

　　The first building of the project was conducted for three months of extreme weather simulation test (high temperature, high humidity + low temperature freeze-thaw). After testing by the China Institute of Building Science, the board has no cracking or deformation, and the energy saving rate is 92% (the design value is 90%).

　　Large-scale supply guarantee

　　Elastic production: According to the construction progress, the Green fish factory will use the "black lamp production line" to operate for 24 hours, with an error rate of <0.5%;

　　Logistics optimization: Use recyclable EPP insulation packaging boxes to reduce transportation loss rate to 0.3% (industry average 2%).

　　On-site technical support

　　A 10-person technical team was stationed on site to solve the following problems:

　　Customized cutting of special-shaped walls (such as balcony corners);

　　Seamless connection with the aluminum mold system to avoid the occurrence of cold bridges;

　　300 industrial workers were trained to master dry construction technology.

　　4. Cooperation results and industry impact

　　Project benefits

　　Energy conservation and consumption reduction: The project's comprehensive energy consumption is 65% lower than that of ordinary residential buildings, and was rated as the "Hebei Province Ultra-low Energy Consumption Building Demonstration Project";

　　Cost optimization: Due to the shortening of the construction cycle by 22 days, Country Garden saved about 4 million yuan in financial costs;

　　Quality benchmark: Zero leakage and zero hollow complaints after delivery, becoming the standard template for insulation engineering in the northern region of Country Garden.

　　Strategic Value

　　Green fish Company was selected as Country Garden's "Green Building Materials Strategic Partner" and subsequently undertakes six near-zero energy consumption projects in Jinan, Zhengzhou and other places;

　　The two parties jointly applied for the Ministry of Housing and Urban-Rural Development's "Technical Regulations on the Application of Aerogel Composite Insulation Board" to promote the formulation of industry standards.

　　Social benefits

　　Green fish Company used this case to expand the northern market, and its sales in North China increased by 210% year-on-year in 2024.

　　5. Experience and enlightenment

　　Technology research is the cornerstone of high-end cooperation

　　In response to the special needs of ultra-low energy-consuming buildings, suppliers need to jointly develop customized materials with real estate companies rather than simply providing existing products.

　　Full-chain risk control determines the success or failure of the project

　　From laboratory data to large-scale implementation, execution risks need to be reduced through mechanisms such as model segment verification, flexible supply chain, and on-site deviation correction.

　　Policy dividends need to be transformed into technical barriers

　　In the context of "dual carbon", enterprises should plan green building materials patents in advance and transform policy requirements into market competitive advantages.
