e-Chromic Technologies, Inc. (formerly US e-Chromic LLC) is developing a reflective electrochromic thin film for windows. Our product will enable property owners of commercial buildings and homes to reduce A/C costs by ~35%. Our patented technology, exclusively licensed from the National Renewable Energy Lab (NREL), transforms ordinary energy wasting windows into highly energy efficient 'smart windows'. Our thin film can be applied from inside an office or residence to retrofit existing windows, thus eliminating the cost, dislocation and landfill associated with purchasing and installing expensive replacement windows.
