Soladigm's Dynamic Glass Exceeds NREL Durability Tests
August 11, 2011

The U.S. Department of Energy's National Renewable Energy Laboratory has confirmed that Milpitas, Calif.-based Soladigm's dynamic glass has passed ASTM E2141-06 durability testing.

NREL tested the glass units under the equivalent conditions of the sun's radiation at an elevated temperature, simulating the effect of real world use in buildings for the lifetime of window glass. More than 50,000 cycles of testing were completed, after which each unit showed no change in physical appearance or performance.

"Soladigm is one of only two companies to have successfully met this durability milestone for dynamic glass technology," says Dr. Anne Dillon, principal scientist at NREL. "Soladigm's samples stood up to our rigorous testing protocol showing no degradation. The stability shown throughout the testing clearly proves that Soladigm has developed a highly durable product."

Says Dr. Rao Mulpuri, chief executive officer of Soladigm: "There are numerous technologies that can achieve color change in transparent materials. An insulated glass unit installed in a building window or a façade needs to withstand the harsh UV and high temperature environments for an extended period of time. The selection of materials and manufacturing technology in our Dynamic Glass unit took into account this important requirement from the beginning. This result at NREL is a significant milestone for Soladigm, validating the commercial viability of our product."

The dynamic glass electronically switches from clear to tinted on demand, enables control of heat and glare in buildings while providing greater comfort, uninterrupted views, and natural daylight. Windows made out of this glass will reduce HVAC energy usage by 25 percent and peak load by 30 percent in commercial buildings, according to the company.
