Core Viewpoint - The construction of "good houses" is a new direction for building development, requiring good standards, design, materials, and services, emphasizing the importance of "good materials" in the construction process [1]. Group 1: Importance of Good Materials - The complete building materials system in China includes over 1,000 products across 30 sub-industries, making it the largest producer and consumer of building materials [1]. - To transition from scale expansion to high-quality development, there is a need for better collaboration between the construction and materials industries [1]. - "Good materials" are essential for building "good houses," with energy-saving, creative, functional, and smart materials being crucial [1]. Group 2: Trends in Energy-Saving Materials - The development trends for energy-saving materials include high performance, such as aerogel glass with superior insulation and soundproofing properties, and composite materials like graphene heating materials that combine multiple functions [2]. - Biomass materials, derived from natural sources like bamboo and wood, are also emerging as new building materials [2]. Group 3: Innovations in Functional Materials - The core factor for promoting the application of advanced energy-saving materials is the high adaptability of performance to cost [3]. - An example of innovative energy-generating materials is the "power-generating glass," which converts light energy into electrical energy through a thin film of cadmium telluride [3]. - The development of new waterproof and soundproof materials is essential to address common living issues in old housing, with a focus on system integration, functional composites, low carbon emissions, and recycling in future research [3].
