The Development Of New Building Materials And Products Is A Requirement Of The Sustainable Development Strategy

For China, where the per capita share of resources such as energy and arable land is only 1/4 of the world average, the coordinated development of the national economy and society with resources and the ecological environment is not just a policy goal but an urgent survival imperative. With 1.4 billion people relying on a finite land base, the strain on natural resources has reached a critical juncture. This is especially true in the construction sector, which accounts for over 40% of China’s total energy consumption and is a major driver of land degradation and carbon emissions.

At present, China's clay solid bricks still account for nearly 80% of the total production of wall materials—a legacy of traditional construction practices that have persisted for centuries. The problems of high energy consumption, land destruction, and pollution are very serious and far-reaching. Each year, brick-making consumes 2.2 billion tons of clay resources, destroying about 120,000 mu of fertile arable land, an area roughly equivalent to the size of Singapore. The process also burns 82 million tons of standard coal annually, releasing vast quantities of dust and carbon dioxide that contribute to urban smog and climate change. In the North China Plain, where brick kilns are concentrated, local farmers have reported falling crop yields due to soil erosion and airborne particulate matter, creating a direct conflict between rural livelihoods and industrial development.

Therefore, the development of organically sustainable building materials and products is not only related to the implementation of our country's sustainable development strategy but also to the healthy development of the building materials industry and the well-being of future generations. As the national economy continues to grow and people's living standards improve, expectations for living and working spaces have evolved beyond basic shelter. Today's urban residents demand buildings that are energy-efficient, aesthetically pleasing, and safe for long-term habitation, with features like natural lighting, sound insulation, and air purification systems becoming standard requirements.

The experience of many countries, from Germany’s passive house movement to Japan’s earthquake-resistant construction standards, has proved that advancing eco-friendly building materials is an inevitable trend of economic development and social progress. The progress of the construction industry no longer merely requires the quality and function of buildings to be perfect; it also demands that they be beautiful, harmless to human health, and resilient to climate risks. This requires the development of multifunctional and efficient new building materials and products, and only in this way can the construction sector adapt to the requirements of social progress.

The use of new building materials and products can significantly improve the function of buildings, increase usable floor area, enhance seismic resistance, facilitate mechanized construction, and reduce costs under the same conditions. Practice in Tianjin, Chengdu, and other cities has proved that under identical design specifications, the use of lightweight, high-strength materials such as autoclaved aerated concrete (AAC) panels can increase effective living space by nearly 10% by eliminating thick load-bearing walls. These materials also reduce building weight by more than 40%, which lowers foundation costs and improves seismic performance—a critical advantage in earthquake-prone regions like Sichuan and Yunnan.

According to the annual completion of 10% of the 240 million square meters of urban residential buildings, widespread adoption of new materials could increase effective living area by about 20 million square meters per year, equivalent to building 250,000 new affordable housing units. This would also reduce comprehensive construction costs by 4%–7%, freeing up funds for urban infrastructure upgrades. In addition, the development of new building materials has had a significant effect on environmental protection and the comprehensive utilization of resources. During the "Eighth Five-Year Plan" period, the development of new wall materials alone saved more than 22 million tons of standard coal in production and heating, reduced land destruction by 150,000 mu, and recycled 95 million tons of industrial waste residue—including fly ash from power plants and steel slag—to cut carbon dioxide emissions by 23 million tons.

As the building materials industry is most closely linked to the construction sector, with 70% of its products used in construction, integrating new materials into architectural design and construction regulations has become a national priority. The government has introduced mandatory green building codes and tax incentives to promote the application of innovative materials like phase-change insulation and recycled steel, driving the transformation of the entire supply chain. The promotion and application of new building materials not only deliver considerable social benefits, such as cleaner air and reduced urban heat islands, but also significant economic returns. For example, the long-term energy savings from applying new thermal insulation materials far outweigh the initial cost of replacing clay bricks, with payback periods typically under five years for residential buildings.

Therefore, the development of new building materials and products is an important part of social progress and improving socio-economic benefits. By embracing innovation in construction, China can not only alleviate resource pressure and mitigate environmental harm but also establish a globally competitive green building industry—one that aligns with its commitment to carbon neutrality and sets a benchmark for sustainable development worldwide.
