Smart glass, also known as switchable or dynamic glass, is redefining the way buildings manage light, heat, and privacy. The innovative material changes its optical properties, becoming tinted or opaque, in response to electrical or thermal signals.
Experts say this technology can significantly improve energy efficiency by reducing heat and sunlight penetration during hot days while maintaining visibility and comfort.
Smart glass is broadly classified into active and passive types. Active variants include electrochromic, liquid crystal, and suspended particle devices (SPD), while thermochromic and photochromic glass fall under passive technologies.
When installed in modern buildings, smart glass creates climate-adaptive envelopes that regulate natural light, block harmful UV rays, enhance thermal comfort, and eliminate the need for blinds or shades.
According to engineers, some smart window systems can even self-adjust to heat or cool, contributing to lower energy consumption and increased occupant comfort.
Emerging innovations now allow smart films to be laminated or sprayed onto existing glass surfaces, offering an affordable way to retrofit older buildings with energy-efficient technology.
