Title of the talk: Passive Heat and Light Management with Advanced Building Skins: From Material Design to Real-World Applications
Abstract: Advanced materials with precisely engineered optical and thermal properties are redefining the frontiers of passive heat and light management, enabling a new generation of renewable building envelopes. These advances stem from innovations in material chemistry, microstructural design, and scalable manufacturing processes. Among the most promising technologies, passive radiative cooling harnesses a versatile materials platform—including microporous polymers, photonic ceramics, and hybrid organic–inorganic composites—engineered into paints, coatings, films, and textiles. These systems are designed to achieve simultaneously high solar reflectance and strong long-wave infrared emissivity, enabling sub-ambient cooling without energy input. In parallel, thermochromic smart windows employ materials such as vanadium dioxide, organic–inorganic perovskites, and hydrogels, fabricated via sputtering, spin coating, and related deposition techniques. These materials enable reversible, temperature-responsive phase transitions for dynamic optical modulation. Performance is intrinsically governed not only by material composition but also by morphology control, device architecture, and processing routes that determine scalability and long-term durability. Integrating these materials into building systems provides a direct pathway to significantly reduce operational energy demand for cooling and heating. Beyond buildings, these platforms demonstrate strong potential in transportation, wearable systems, and industrial thermal management. Despite rapid progress, key challenges remain in large-scale manufacturing, cost-effective system integration, and long-term reliability under real-world conditions. This presentation will highlight recent scientific breakthroughs in passive thermal and optical materials and outline the critical engineering strategies required for successful commercialization. By bridging fundamental materials discovery with practical deployment, advanced building skins offer transformative solutions for decarbonizing the built environment and advancing sustainable development across sectors—representing a powerful convergence of materials science, engineering innovation, and climate action.
