Comparative Review on Smart Window Technologies: Electrochromic, Thermochromic, Photochromic, and Liquid Crystal Windows

  • Unique Paper ID: 180428
  • PageNo: 1843-1847
  • Abstract:
  • Smart window technology has emerged as a pivotal solution in sustainable architecture, offering dynamic modulation of light and heat to improve energy efficiency and occupant comfort. This paper presents an integrated comparative analysis of four major smart window technologies: Electrochromic (EC), Thermochromic (TC), Photochromic (PC), and Liquid Crystal Displays (LCDs). The technologies are evaluated based on their working principles, switching dynamics, energy efficiency, optical performance, limitations, maintenance, and suitability and other architectural applications. Additionally, this paper discusses future trends, including hybrid systems that will further enhance the performance and integration of smart windows in intelligent buildings
