By modulating the solar energy flowing into a building, electrochromics
can tune the amount of heat and light according to the needs of the building's HVAC system and the occupants.
For south-facing large-area windows, electrochromics
demonstrated 44-59% and 8-23% daily lighting energy savings over 15% and 50% visible transmissivity windows, respectively.
However, this transition metal oxide electrochromics
show a slow response time (tense of seconds) and high processing cost.
Major players in this industry include, SAGE Electrochromics
A 20-month field study was conducted to measure the energy performance of south-facing large-area tungsten-oxide absorptive electrochromic
(EC) windows with a broad switching range in a private office setting.
The program has already resulted in the development of electroactive polymers, micro-flexible electronics, nanoclays, and electrochromics
useful for military-grade active sensing packages that detect damage of changes in environmental conditions.
