New Visual Media Group (NVMG) has introduced a window technology that the company says could lead to a six-fold increase in energy efficiency while costing about 90 percent less than the most comparable window alternatives on the market.

As DWM first reported in March 2015, NVMG has developed what it calls ElectroPolymeric Display (EPD) technology, which is essentially a super-thin sheet of polymer film that’s installed inside insulating glazing units (IGUs). The shade, which can be almost any color or design, can keep heat out during the summer and in during the winter. It can be electronically lowered and raised automatically or with a Wi-Fi signal.

According to NVMG, independent laboratory tests show that windows with EPD technology register a solar heat gain coefficient (SHGC) of 0.034, which is six times better than the best windows on the market and 20 times better than basic window glass.

“Cost is the greatest advantage the NVMG product has over electrochromic technology, which adds $100 per square foot to the cost of the typical window,” said NVMG director Elliott Schlam, who’s a fellow with the Society for Information Display. “Very few businesses and far fewer homes will be able to justify that type of expense. The NVMG technology will add only $4 per square foot to the cost of the typical window, meaning our product will pay for itself in about 18 to 24 months.”

“The EPD technology shows great promise,” said Anna Dyson, director of Rensselaer Polytechnic Institute’s Center for Architecture, Science and Ecology working in collaboration with the international architectural firm Skidmore, Owings & Merrill, in a statement released by NVMG. “This technological approach could allow customers and building occupants more flexibility and dynamic control over the aesthetics and environmental performance of their windows.”

“There is a significant market among hospitals who wish to replace the old-fashioned curtains with glass doors where privacy screens can be electronically controlled with the click of a button,” said Mike Bradberry, president of Door Control, Inc., a Jacksonville, Fla. provider of automatic and sliding doors for the healthcare industry, in a statement released by NVMG. “Unfortunately, the electrochromic controlled doors available today are cost-prohibitive with prices as high as $250 per square foot. The NVMG technology holds the promise to meet the strict hospital and other automated door market demands.”
