ABSTRACT
Fenestration, such as windows, plays an important role in modern architecture as it has significant impact on regulating energy efficiency and providing comfort to the residents of buildings. Development of a novel, simple, and economical synthesis of electrochromic (EC) materials is the first step in realizing high-performance smart windows. This chapter discusses the current state-of-the-art strategies in electrochromic (EC) devices and their performances. Moreover, the current challenges arising from material selection that affects smart window performance are discussed, and feasible solutions are provided. Fabrication processes and packaging also play critical roles in the development of multifunctional and energy-efficient smart windows. This chapter also discusses the concept of self-powered multifunctional smart windows where the windows are powered by sustainable energy in the daytime, while dynamically controlling the solar radiation into buildings through transmittance regulation and enabling resident's privacy.
