Electrochromic Window: Smart Glass for Energy Efficiency and Comfort
An electrochromic window, also known as smart window or dynamic glass, is a technologically advanced window that can change its tint or opacity in response to an electrical voltage. These windows help regulate natural light and heat, reduce glare, improve energy efficiency, and enhance occupant comfort in buildings and vehicles.
How Electrochromic Windows Work
Electrochromic windows consist of multiple thin layers of materials, including a transparent conductive layer and an electrochromic layer, sandwiched between glass panes. When a low-voltage electric current is applied:
Ions move between layers, causing the glass to darken (tint).
Reversing the current returns the glass to its clear state.
This tinting process can be manually controlled or automated using sensors that detect sunlight or temperature.
