SAGE was founded in 1989 by John Van Dine, who is the company’s president and CEO.  Mr. Van Dine’s mission for the company was the same then as it is now: to bring to market a durable, reliable and high-performance energy-saving electrochromic technology for buildings.

SAGE began its existence in a small laboratory in Valley Cottage, N.Y., and then moved onto the campus at Rutgers, the State University of New Jersey in the school’s Department of Ceramic Science and Engineering. After several years of R&D, the company was ready to move into its pilot line phase. At that point, in late 1998, SAGE moved west to Minnesota, “the Silicon Valley of the window industry.”  SAGE spent the next five years refining its production processes and further developing and testing its products in its pilot line facility. Samples from this operation were tested over the years by several third parties, including the U.S. Department of Energy, and deployed to numerous beta sites around the United States to be evaluated for performance in real life applications. In 2005, SAGE moved into its current 60,000-sq. ft. state-of-the-art manufacturing facility.
