On the occasion of the 8th anniversary of the start-up,# Shaohai Huiyue's new series of columns were launched, decrypting and displaying in detail Shaohai Huihui's cutting-edge technical strength in the fields of smart residence and new materials, and exploring more possibilities brought by new quality productivity to life and industry.

In this issue, let's feel a green, low-carbon and sustainable development revolution set off by Shaohaihui in the whole construction process through new materials and new technologies, so as to make the building energy-saving and carbon-reducing scheme more secure and pragmatic.

Energy saving and carbon reduction in the construction sector ushered in a clear "timetable" and "road map".

On May 29, the State Council issued the "2024-2025 Energy Conservation and Carbon Reduction Action Plan" (hereinafter referred to as the "Plan"), clarifying that my country will implement special actions for energy conservation and carbon reduction by field and industry, and give full play to the economic, social and economic benefits of energy conservation and carbon reduction. Ecological benefits lay a solid foundation for achieving the goal of carbon neutralization.

The program focuses on "naming" energy-saving and carbon-reduction actions in the construction sector, and clearly defines specific paths to guide and promote the transformation of construction methods and the transformation of existing buildings, indicating the direction of action to further boost energy-saving and carbon-reduction work.

On the one hand, it is necessary to speed up the transformation of construction methods. Strictly implement mandatory standards for building energy conservation and carbon reduction, strengthen green design and construction management, and develop and promote new building materials and advanced technologies. Vigorously develop assembly buildings, actively promote intelligent construction, and accelerate the construction of building photovoltaic integration.

On the other hand, it is necessary to promote the transformation of stock buildings. Implement policies related to large-scale equipment renewal, combine urban renewal actions, old community renovation and other work, promote the renewal and upgrading of exterior windows (curtain walls) and exterior walls (roofs) insulation, and accelerate building energy-saving renovation. Implementation of energy-saving doors and windows to promote action.

As a "partner" in the development of green buildings, Shaohaihui aims at green ecology, livability and industry, wisdom and resilience, and strengthens the integration of resources. through new materials and new technologies to build "good houses" and good projects in the field of building energy conservation and carbon reduction, set off an industrial revolution of green, low-carbon and sustainable development.

New materials plate, less haihui in Henan Hebi landing Haili magnesium alloy lightweight industrial park, joint Nobel Prize winner Professor Shechtman, Xi'an University of Technology and other production and research institutions, to achieve the mass production of aluminum magnesium alloy, metal composite plate, the full promotion of green building materials.

At the same time, around the whole scene field of architecture, Haili new materials research and development of metal veneer, metal honeycomb panel, metal composite integrated panel, etc., to create low-energy curtain wall, metal composite roof and other projects, enabling urban renewal green upgrade.

In the Hefei Garden Expo Project, Haili applied self-developed titanium-zinc plate metal roofing to rebuild the building roof ecology, outstanding performance in the field of urban ecological restoration, and was approved by the Ministry of Housing and Construction for the first batch of typical cases of urban renewal.

In addition, in the field of non-metallic materials, Shaohaihui continues to promote the layout of the carbon ceramic industry, relying on the technical advantages of carbon ceramic basic materials, to achieve in the home, home appliances, new energy and other scenes of supporting products landing.

New technology plate, less haihui focus on Haili, Qin Heng construction technology and other enterprises in the building envelope system of iterative innovation, to BIPV, ultra-low energy consumption, external wall insulation and other technologies as the lead, in the country to land more environmentally friendly, more energy-saving solutions.

In Qingdao, Haili applied BIPV technology to the eagle wing tower over 80 meters in Qingbei Gaoke Park, installing nearly 3000 pieces of CdTe (cadmium telluride) photovoltaic power generation glass of different sizes, covering an area of about 3000 ㎡, which can achieve an annual power generation of 200000 kw · h. While meeting its own power consumption, excess power will be incorporated into the power grid, reducing operating costs and reducing carbon dioxide emissions by about 200 tons, equivalent to 600 trees.

In Xiong'an New Area, Haili in the future of the city facade curtain wall innovation application BIPV, laying photovoltaic solar panels, to create a light storage straight soft, low-carbon building cluster, the first to achieve the building body energy cycle.

In Hohhot, Qin Heng Construction Science and Technology participated in the construction of the first ultra-low energy consumption building in the severe cold region. The exterior wall system uses thermal insulation materials nearly 3 times thicker than regular materials to reduce the heat transfer coefficient, meet the building's thermal insulation performance and reduce the energy consumption of cold and heat sources.

In addition, in the door and window system, the passive ultra-low energy consumption doors and windows independently developed by Haili have passed the certification of the German Passive House Research Institute (PHI), and the K value has dropped below 1.0, which can save 50% of energy consumption and enable the building to be greener and lower carbon.

In the next step, Shaohaihui will further upgrade new materials and technologies for green buildings, and implement more typical cases of energy saving and carbon reduction, so as to provide excellent experience and reference for building energy saving and carbon reduction.
