Glass has been an integral part of our lives for centuries serving as a transparent material widely used in windows, doors, mirrors and other applications. However, glass is all set to undergo a massive transformation with the emergence of smart glass that is responsive to external stimuli and can change its properties such as transparency, color and opacity on demand. Let us delve deeper into the exciting world of smart glass, its capabilities and potential applications.

What is Smart Glass?

Smart glass, also known as switchable glass, is a innovative material that has the ability to change its optical properties when stimulated either electrically, chemically or thermally. Unlike conventional glass which maintains a fixed transparency, smart glass can transition between opaque and transparent states according to the applied stimulus.

There are different types of smart glass available in the based on the technology used — electrochromic, photochromic and thermochromic. Electrochromic glassdarkens when voltage is applied and becomes transparent when turned off. Photochromic glass dims when exposed to UV light while thermochromic glass changes with temperature variations.

These intelligent properties allow smart glass to dynamically control the amount of light, heat and privacy passing through them as per the surrounding conditions or user preferences. This makes them an apt replacement for traditional glass in a variety of architectural and automotive applications.

Potential Architectural Uses

One of the biggest applications of Smart Glass lies in the construction industry where it can greatly enhance the energy efficiency of buildings. Smart windows that can switch between transparent and opaque states can efficiently regulate temperature, glare and solar heat gain inside rooms and offices.

During sunny days, the windows can automatically darken to block unwanted solar radiation from overheating interior spaces. In winters, the same glass becomes clear to allow warmth-giving sunlight inside. This thermoregulating ability of smart windows can significantly reduce the energy consumed for cooling and heating thereby lowering carbon footprint and utility bills.

Many skyscrapers and large commercial buildings are now being designed with smart glass facades that provide adjustable solar control and privacy. The dynamic glass external walls not only make buildings aesthetically appealing but also cut operational costs through improved thermal insulation. Hospitals, schools and other sensitive buildings are also leveraging smart windows for controlling excess light entry to avoid disturbance.
