Achieving carbon peak and carbon neutrality is a systematic project that requires collaborative efforts from all parties. At the same time, "the pressure to reduce carbon emissions primarily falls on urban areas, specifically in terms of energy structure, industries, buildings, and transportation. Among these, the carbon emissions throughout the building process account for over half of China's total carbon emissions, making energy-saving and emission-reduction in buildings particularly crucial." Wang Jun, General Manager of the North-West Institute of Architectural Design, China State Construction Engineering Corporation, stated at the 2021 Eurasian Economic Forum • 5th Green Building and Urban Sustainable Development Summit Forum on the afternoon of October 18.

The crucial aim of energy conservation and emission reduction in construction is to achieve urban sustainability. Sustainability has become a major issue in current urban development, particularly in the growth of large cities.Improving urban environments and achieving sustainable urban development are also significant strategic goals proposed by China in the 21st century.

"How can cities achieve sustainable development in environmental improvement? The answer is simple: by embracing greenification and ecologicalization. Green buildings are a crucial aspect in promoting the green development of cities, enhancing urban environments, and realizing sustainable urban development," stated Wang Shengxue, the President of Shaanxi Real Estate Research Association.

Incorporate green building requirements into construction engineering standards

Wang Jun emphasized the need to vigorously promote green concepts, integrating them into architecture. He advocated for innovation led by architectural design, driving the development of new types of buildings, and advancing decentralized renewable energy systems, shifting buildings from energy to a new energy ecosystem. Simultaneously, he highlighted the importance of closely integrating digitalization and intelligence, achieving effective data detection and collection through the construction of new infrastructure, and utilizing data management platforms for comprehensive management and planning of urban energy. Furthermore, he called for opening up market channels, incorporating the construction industry into the carbon emission trading system, and exploring various green financial support methods.

Professor Jianfeng Ma from Northwest UniversityShareWe have identified four categories of building carbon reduction technologies: 1) Carbon reduction technology; 2) Low-carbon technology, such as photovoltaic power generation (not yet stable); 3) Zero-carbon technology, which achieves zero waterpower emissions, although the technology cost is currently high; and 4) Negative-carbon technology, including land use and forest carbon sinks.

Majiong Feng stated, "We are now focusing on carbon neutrality and peak carbon emissions for construction materials at their source, aligning with carbon emissions reports. Through specific carbon emissions standards and a new evaluation system, we begin with green, low-energy facades on buildings, aiming to reduce consumption and achieve emission reductions."

The Director of Green Building at the Ministry of Housing and Urban-Rural Development's Science and Technology Industrialization Center, Liang Hao, stated that in 2020, newly constructed green buildings accounted for 77% of the total newly built residential buildings in cities and towns in China. The cumulative number of green building certification projects reached 24,700, with a floor area exceeding 2.569 billion square meters, and modular construction also saw growth.
