Glass plays a vital role in protecting interiors from external elements like rain, wind, and extreme temperatures while ensuring transparency and maintaining structural integrity. To achieve these objectives, glass must control several factors, including:
This article focuses on the first two elements—Solar Radiation and Temperature—as moisture and structural load management often involve framing and gasketing systems. Sound control will be addressed in a future article.
Understanding Glass and Solar Energy
Visible light is just a small portion of the electromagnetic spectrum, ranging from 380 to 780 nanometers (nm) or 400 to 790 terahertz (THz). Glass also interacts with other wavelengths of solar energy, such as:
To measure how effectively glass performs, three primary metrics are used:
Optimizing Glass Performance
The goal for most glass applications is to maximize VLT for optimal natural light while minimizing U-value and SHGC to control heat transfer and solar gain. Achieving this balance often involves:

3D concrete tiles are a modern type of building and decorative material, made from concrete or geopolymer, with a raised three-dimensional surface featuring geometric, natural, or artistic patterns. Thanks to their strong visual effects, 3D concrete tiles not only provide high aesthetic value but also help improve sound insulation, thermal resistance, and waterproofing. With advantages in durability, ease of construction, and environmental friendliness, especially when combined with recycled materials such as ground brick waste, 3D concrete tiles are becoming an ideal material solution for both interior and exterior modern spaces.

Amid rapid urbanization and rising aesthetic demands in modern construction, smart and sustainable materials are gradually replacing traditional solutions. Among them, luminescent concrete has emerged as an innovative trend that combines lighting functionality with the mechanical durability of conventional concrete. Not only does it offer a distinctive visual appeal, but it also enhances safety, conserves energy, and improves spatial efficiency in low-light environments. With vast potential for applications in transportation infrastructure, landscape architecture, and smart urban design, this material is paving the way for new directions in the construction industry during the era of green technology.

With the increasingly strong trend of construction development, the number of new construction projects is rapidly increasing over time. However, this process also comes with issues related to construction quality, as some projects do not meet standards or deteriorate quickly, leading to the appearance of cracks on the concrete surface. These cracks not only affect aesthetics but also pose dangers to users, reducing the lifespan of the structures. Recognizing these shortcomings, the MICP method (Microbially Induced Calcite Precipitation) has been researched and applied as an effective solution. This method helps to repair cracks in concrete, creating a protective layer and enhancing the structure's resistance to environmental impacts, thereby increasing the lifespan and ensuring safety for construction projects.

In the context of an urgent global shift toward green materials and sustainable development, recycling concrete from demolished structures has become a significant trend. Instead of being discarded, this old concrete is processed and reused as aggregate for new concrete, contributing to waste reduction and minimizing environmental impact. However, to ensure the quality and accuracy of the recycling process, it is essential to thoroughly understand the characteristics and properties of these “new aggregates” when used in fresh concrete mixtures. In this context, the application of computer vision technology emerges as an innovative approach—allowing for precise analysis and evaluation of material features, thereby enhancing the efficiency and reliability of recycled concrete processing.
