Smart glass, also known as switchable or dynamic glass, is revolutionizing the way sustainable structures are designed and operated. By intelligently adjusting its light transmission properties in response to environmental conditions or user requirements, smart glass promotes energy efficiency, occupant comfort, and architectural flexibility. Its versatility makes it a valuable asset in the pursuit of green building standards, contributing to both environmental goals and enhanced user experiences. As sustainability becomes an essential element of modern construction, understanding smart glass applications is critical for forward-thinking architects, engineers, and property owners.
