Market Growth Factors

The smart window market is a rapidly growing market enabled by technological advancements. Smart windows in electrochromic, photochromic, thermochromic and liquid crystal technology are employed to improve the energy efficiency, comfort, and privacy of buildings by reducing or increasing the transmission of visible light through windows in response to stimulus. Other features such as the ability to control the window remotely and to program it using Internet of Things (IoT) technology are driving market growth. Furthermore, wide-ranging investment in the development of nanotechnologies and materials is improving performance and lowering the cost to consumers.

Another major driver for the smart window market is energy-efficient and sustainable buildings. Smart windows can automatically adjust to environmental conditions, reducing the need for artificial heating and cooling, leading to energy and carbon savings. For their role in blocking excess heat and ultraviolet (UV) radiation in extreme thermal environments, their use can reduce the energy demand for air conditioning. The expansion of smart window use is part of a more sustainable construction trend.

The growing preference for comfort and aesthetics by consumers is another factor driving the smart window market. Smart windows also have aesthetic appeal due to their streamlined designs. They also control daylighting, temperature, glare and UV exposure in commercial and residential buildings. Government programs, such as tax credits, rebates, grants, and green building certification programs, have encouraged their adoption. Urbanization and the growth of smart cities have increased the demand for energy-saving smart windows, which are used to combat urban heat islands and promote sustainability.
