Above is an LBL electrochromic window, showing the bleached condition, intermediate coloration, and fully colored (top to bottom). The window is constructed of thin films of tungsten oxide and lithium nickel oxide laminated with a polymer ion conductor. The visible transmittance range is Tv = 0.68-0.10 and solar transmittance range is Ts = 0.47-0.07.
How Electrochromic Materials Work At right is an LBL electrochromic window, showing the bleached condition, intermediate coloration, and fully colored (top to bottom). The window is constructed of thin films of tungsten oxide and lithium nickel oxide laminated with.
Electrochromic windows in a fully colored state (left column), intermediate tinted state (middle column), and clear bleached state (right column). Electrochromic coatings (EC) are switchable thin-film coatings applied to glass or plastic that can change appearance reversibly from a clear to a dark Prussian Blue tint when a small DC voltage is applied.
Electrochromic windows change tint with a small applied voltage, providing building owners and occupants with the option to have clear or tinted windows at any time, irrespective of whether it’s sunny or cloudy. EC windows can be manually or automatically controlled based on daylight, solar heat gain, glare, view, energy-efficiency, peak …

LBL -35486. Abstract. The performance factors which will influence the market acceptance of electrochromic windows are reviewed. A set of data representing the optical properties of existing and foreseeable electrochromic window devices was generated. The issue of reflective versus absorbing electrochromics was explored.
Switchable electrochromic (EC) windows have been projected to significantly reduce the energy use of buildings nationwide. This study quantifies the potential impact of electrochromic windows on US primary energy use in the commercial building sector and also provides a broader database of energy use and peak demand savings for perimeter zones than that given.
