Recently, Changle Technology and Dongpeng Holdings, a leading building materials enterprise, have officially reached a strategic cooperation. The two sides will jointly conduct product research and development and application expansion of radiative cooling technology (also known as electricity-free cooling technology) in building materials such as tiles, rock slabs, and soft ceramics.Against the backdrop of increasingly frequent summer heatwaves, the next upgrade of building materials will undoubtedly require stronger climate adaptability and sustainability.
This cooperation, relying on Changle Technology's technical accumulation in radiative cooling and Dongpeng Holdings' long-term practice in building materials manufacturing, will further promote the large-scale application of new cooling materials in the building materials field, create more climate-resilient functional building materials, and provide innovative energy-saving cooling solutions for the construction industry.
The cutting-edge technology featured in Science - Changle's radiation cooling technology
Changle Technology has long been dedicated to the research and development of materials for radiation cooling (electricity-free cooling) and their industrial application. It has established a diverse product system covering coatings, powder coatings, window films, rolls, textiles, car films and tiles, which are widely used in buildings, industrial equipment, transportation and personal protection. The technology has been implemented in nearly 30 countries and regions around the world, with an application area of over 410,000 square meters.
Changle Technology's radiation cooling ceramic material sets a new industry record in performance
Radiation cooling ceramics are a key focus of Changle Technology's research on new materials. This material, inspired by nature and designed optically, features a multi-level porous structure combined with high bandgap nanoparticles, achieving a solar reflectance of up to 99.6% and a mid-infrared emissivity of 96.5%, breaking the current record in the field of radiation cooling. The research results have been published in the top international journal Science.
The refrigeration ceramic materials developed by Changle Technology not only lead the world in optical performance but also feature excellent weather resistance, self-cleaning properties and mechanical strength, making them suitable for complex outdoor applications such as building facades and urban road surfaces.
Based on this material technology, Changle Technology has developed two major product lines: electricity-free refrigeration exterior wall tiles and permeable pavement tiles.
The electricity-free refrigeration exterior wall tiles can effectively alleviate the energy consumption pressure of building cooling. Compared with ordinary exterior wall tiles, the full application of electricity-free refrigeration exterior wall tiles is expected to reduce air conditioning energy consumption by about 20% throughout the year, significantly improving the energy efficiency of buildings.
The electricity-free refrigeration permeable pavement tiles combine the functions of cooling and water permeability, and are specifically designed to address urban heat island effects and waterlogging problems. They are preferred materials for building sponge cities. Changle Technology has jointly promoted the pilot application of permeable pavement tiles with Hysan Development and the Hong Kong Science and Technology Parks Corporation, and has completed the pilot application in Hong Kong.
This cooperation with Dongpeng Holdings marks an important advancement for Changle Technology in the tile sector. Both parties will work together to integrate core technologies and manufacturing systems, and jointly create a new generation of green functional building materials with cooling capabilities, further exploring the practical value of tile products in energy conservation and carbon reduction, achieving a dual breakthrough in technological innovation and industrial scale.
The Pride of Domestic Products - Dongpeng Holdings
A Benchmark in the Building Ceramics Industry
As a leading enterprise in the building ceramics sector, Dongpeng Holdings has deeply integrated green development into its corporate DNA. With the mission of "blending technology and art to create a beautiful living environment," it continuously leads the green and low-carbon transformation of the manufacturing industry. Through innovative practices such as the recycling of waste materials and the reuse of water, the company has significantly reduced resource consumption in the production process, solidifying the foundation of its "green manufacturing" strategy. Dongpeng Holdings is highly regarded as the "pride of domestic products" due to its outstanding product quality and continuous innovation.
High-tech, high-efficiency and high-quality - Dongpeng Holdings leads the low-carbon transformation of the building materials industry. Its ecological stone production base in Hukou, as a top domestic benchmark for ecological stone intelligent manufacturing, adheres to the concept of a "zero-waste factory", achieving full-process low-carbon and environmentally friendly, zero-emission operations. The base has increased the proportion of raw material solid waste to 70% through breakthrough technologies and adopted a green non-burning process to keep the carbon emissions per unit product at 0.66kg CO₂e, reducing the comprehensive energy consumption by 40% compared to traditional tiles. It sets a benchmark for the green building materials industry.
Under the global trend of manufacturing's accelerated transformation, Dongpeng Holdings has taken high technology, high efficiency and high quality as its core directions, constantly promoting lean manufacturing to a higher standard through formula optimization, process upgrading and intelligent production line construction. Through this cooperation, Changle Technology will empower Dongpeng Holdings' key product lines with radiative cooling technology, especially in core product lines such as exterior wall tiles, soft ceramics and new building materials, leveraging the complementary advantages of both parties in technology and manufacturing to jointly advance the performance improvement and industrial upgrading of green building materials.
The next-generation green building materials - stronger climate adaptability
Recently, the national electricity load has repeatedly reached new highs, with nearly 90% of the increased load in summer coming from air conditioning for cooling. Facing the rising energy consumption pressure, we are taking an internal approach to the building materials system to provide new possibilities for building insulation and urban cooling.
Insulation, cooling energy saving, and climate adaptability are becoming the basic capabilities that the next-generation building materials system must possess. The collaboration between Changle Technology and Dongpeng Holdings is timely and represents an active response to the transformation of building materials in the era of high temperatures.
Changle Technology will continue to focus on radiative cooling as its core direction, drive the evolution of the traditional manufacturing system with emerging technologies, and jointly promote the performance upgrade of green building materials in the era of high temperatures, contributing to the construction of more livable and resilient human settlements.
