Given the need to keep the benefits of glazing and overcome the limitations of conventional control strategies, a number of emerging technologies have been applied to glazing that provide “dynamic” rather than “static” control options. Simply defined, dynamic glass can respond to changing light conditions by clearing or darkening as light levels change. This is essential not to obstruct customer view to displayed cars at any time. Some examples include photochromic or thermo chromic glass that respond to UV light or heat and tint accordingly. This type of dynamic glazing requires no electricity and has been used most commonly in products like eye glasses, causing them to darken in bright light and clear in less light.
