以“三新”思维引领未来人居 长沙经验助力绿色建材与“好房子”融合发展

Core Viewpoint - The event held in Nanjing on January 23, 2026, focused on integrating green building materials with high-quality construction, highlighting Changsha's innovative practices in promoting green materials through a "three new" thinking approach [1] Group 1: Institutional New System - Changsha has implemented an innovative "BIM+M+EPC" model that facilitates collaboration across the entire design, production, and construction process, supported by digital design and intelligent manufacturing [2] - The model has received a national invention patent and incorporates a three-dimensional control system to include green material enterprises in the core collaboration circle, addressing industry chain collaboration issues [2] - A policy mandates that the application ratio of green materials in new green buildings must not be less than 60%, providing institutional support for green practices [2] Group 2: Application New Scenarios - Changsha has established a green building material application information platform that assigns "digital IDs" to key materials, enabling traceability throughout the process [3] - The city has developed a progressive smart construction scenario matrix from 1.0 to 5.0, based on "BIM+prefabrication," to achieve precise material matching, intelligent production, smart construction, and urban collaboration [3] - The Hunan Creative Design Headquarters Building serves as a 4.0 scenario example, demonstrating a 25% reduction in building energy consumption through the integration of green materials and digital technology, earning a three-star green building rating [3] Group 3: Industrial New Ecology - In response to market demands for green materials transitioning from "basic functions" to "integrated empowerment," Changsha is focusing on ten integrated directions, including structural insulation and soundproofing [4] - The city has fostered a new type of component industry cluster by forming industry-academia-research alliances, publishing product technology lists, and enhancing policy support, resulting in over 100 certified green material enterprises [4] - A dual-level "online + offline" collaborative system has been established for regulatory oversight, ensuring closed-loop management through various verification methods, supported by technical guidelines for calculating green material application ratios [4] - The integration of the new system, new scenarios, and new industries is essential for synchronizing the development of green materials with high-quality housing construction [4]
