Zhejiang Jingtai Glass Technology: Practicing the concept of green and low-carbon development, "renewing" the lifeline of buildings with energy-saving glass.

Building energy conservation and carbon reduction are crucial components of achieving the national "dual-carbon" strategic goal. Glass, as the largest transparent material in building envelopes, directly impacts a building's energy consumption. With "green building materials" and "good houses" being included in the government work report for the first time, and with building energy conservation and green building standards undergoing rapid iteration and upgrading, Zhejiang Jingtai Glass Technology Co., Ltd. is integrating energy-saving and low-carbon concepts into the research, development, production, and application of every piece of glass through continuous innovation and pragmatic product practices, contributing to energy conservation and carbon reduction throughout the entire building lifecycle.

Policy Focus: Energy Conservation and Carbon Reduction Goals Drive Accelerated Green Building Development
In 2026, "good houses" were included in the government work report for the first time. Building safe, comfortable, green, and intelligent "good houses" has become a key task clearly deployed at the 2026 National Housing and Urban-Rural Development Work Conference. Behind this requirement is a systematic promotion of building energy conservation and carbon reduction across the entire chain—from producing green building materials with lower energy consumption in the building material production stage, to reducing energy consumption through prefabricated construction during the construction process, and further to improving thermal insulation performance throughout the building's entire lifecycle, energy conservation and carbon reduction work has comprehensively permeated all aspects of the construction industry. In April 2026, the General Office of the CPC Central Committee and the General Office of the State Council issued the "Opinions on Doing a Higher-Level and Higher-Quality Job in Energy Conservation and Carbon Reduction," proposing to "strictly manage the energy efficiency of new buildings, optimize the energy-saving and carbon-reducing design of buildings, promote the large-scale development of ultra-low energy consumption buildings, and build safe, comfortable, green, and intelligent 'good houses.'" At the national standard level, the "Calculation Method for Energy Balance Value of Architectural Glass" (GB/T 47553-2026) was released on April 30, 2026, and will be implemented on November 1; the "Evaluation Requirements for Energy-Saving and Carbon-Reducing Technologies in the Flat Glass Industry" (GB/T 47395-2026) was released on March 31, 2026, and will be implemented on October 1. The revised "Insulating Glass" (GB/T 11944-2025) was released in December 2025 and will officially come into effect on July 1, 2026. The release of this series of standards provides clearer technical guidance for the standardized application of energy-saving glass, marking a shift in its role in green buildings from a "nice-to-have" to a "rigid demand."

At the local level, Zhejiang Province is also making firm strides in promoting green buildings. In January 2026, the provincial construction industry work conference clearly identified "deepening the implementation of the green building creation action" as one of its three strategic goals. The 2026 Zhejiang Provincial Construction Energy Conservation and Green Building and Related Engineering Construction Standards Formulation and Revision Plan continues to be implemented, pushing building energy conservation standards towards a more refined and systematic direction. Zhejiang Province also plans to launch the construction of 20 zero-carbon industrial parks in 2026, implement more than 100 energy-saving and carbon-reducing technological transformation and energy-consuming equipment renewal projects, freeing up energy consumption space equivalent to more than 3 million tons of standard coal annually. Driven by the synergy of policy and market, technology and standards, green building materials are entering a fast track of large-scale, high-quality development.

Market Expansion: Green Building Materials Exceed 300 Billion Yuan, Energy-Saving Glass Sees Surge in Demand

In September 2025, six departments, including the Ministry of Industry and Information Technology, jointly issued the "Work Plan for Stabilizing Growth in the Building Materials Industry (2025-2026)," which clearly requires that the operating revenue of green building materials exceed 300 billion yuan by 2026, with a significant improvement in green, low-carbon, and digital development levels. The plan proposes to strengthen the advanced inorganic non-metallic materials industry, continue to carry out green building materials promotion activities in rural areas, and include energy-saving renovation of building doors and windows in the scope of tapping existing consumption potential.

Energy-saving glass, as an important category of green building materials, is experiencing rapid release of market demand. According to research statistics from WENKH, the global low-emissivity (Low-E) glass market sales reached US$16.693 billion in 2026 and are projected to reach US$25.333 billion in 2033, with a compound annual growth rate of 6.14% from 2026 to 2033. According to data from research firm QYR, the global market for Low-E glass for residential use reached 16.3 billion yuan in 2025 and is projected to reach 28.13 billion yuan by 2032, representing a compound annual growth rate of 8.2%.

In the field of building energy conservation, Wang Gang, a National People's Congress (NPC) deputy and chairman of Jinjing Technology, calculated at the 2026 NPC session that if all 2 billion square meters of new buildings constructed annually used energy-saving glass, compared to ordinary single-pane glass, approximately 23.6 billion kilowatt-hours of electricity could be saved annually for heating and 7.05 billion kilowatt-hours for cooling, totaling approximately 30.6 billion kilowatt-hours of electricity savings per year. Peng Shou, an NPC deputy and academician of the Chinese Academy of Engineering, suggested accelerating the formulation of national standards for the application of green building materials and promoting the implementation of mandatory policies for their application, making green building materials a standard feature of both new and renovated buildings.

Currently, my country has approximately 107 billion square meters of existing buildings, of which about 80% are high-energy-consuming buildings, and old buildings over 20 years old account for 40%. With the continued expansion of the market for energy-saving retrofits of existing buildings, the demand for energy-saving glass in the existing market is rapidly increasing, providing broad application prospects for products such as Low-E insulated glass and nano-energy-saving glass.

Product Empowerment: Low-E Insulated Glass, the "Transparent Barrier" for Green Buildings Low-E insulated glass, the core energy-saving product of Zhejiang Jingtai Glass Technology, is a crucial supporting material for building energy conservation and carbon reduction. Low-E (low-emissivity) glass, through a surface coating of multiple layers of metal or metal oxide low-emissivity films, exhibits high transmittance of visible light while effectively reflecting mid- and far-infrared thermal radiation. Low-E insulated glass combines Low-E glass with an insulated structure, filled with dry air or an inert gas (such as argon), thereby significantly reducing indoor and outdoor heat exchange and decreasing building cooling and heating energy consumption.

Double-silver Low-E coating enables selective transmission of solar radiation—blocking heat from entering the room in summer and reducing indoor heat loss in winter, achieving dynamic energy saving. In practical applications, Low-E insulated glass not only reduces building operating energy consumption and carbon emissions but also effectively blocks ultraviolet rays, protecting indoor furniture and decorations from fading, offering the dual benefits of energy saving and health.

Another energy-saving product from the company—nano-energy-saving glass—also demonstrates significant value in the field of energy-saving renovation. Developed with support from the "Eleventh Five-Year Plan" National Science and Technology Support Program's "Research on Key Technologies for Building Energy-Saving Renovation" project, this product boasts excellent light transmission performance and comprehensive properties such as heat insulation, UV protection, and noise reduction, making it particularly suitable for energy-saving renovation projects in existing buildings. Coated energy-saving glass, made by applying a nano-transparent energy-saving glass coating to the glass surface, eliminates the need to replace existing window frames, facilitating construction and achieving a comprehensive energy saving rate of 25% to 30%. With the continued expansion of the market for energy-saving renovation of existing buildings, it is poised for broad application prospects.
