World's Largest Smart Glass Roof Debuts Today at the

MILAN, ITALY --(Marketwired - May 01, 2015) - Starting now through October 31, 2015, over 20 million people are expected to attend Expo Milano 2015 and can experience SPD-SmartGlass in the roof of the USA Pavilion of the World's Fair. The pavilion is topped by an all-glass SPD-SmartGlass roof using technology patented by Research Frontiers ( NASDAQ : REFR ) and manufactured under license by leading Italian glass company, Isoclima under their CromaLite brand of SPD-SmartGlass. The USA Pavilion features a vertical farm as well and an open design to create a feeling of transparency and spaciousness. Joining Charlie Faas, CEO of the USA Pavilion, at the official opening ceremony for the USA Pavilion were various officials including U.S. Ambassador to Italy John R. Phillips, Ambassador Philip T. Reeker, Consul General Milan, and Ambassador Douglas T. Hickey, who was appointed in December by US Secretary of State John Kerry to be Commissioner General to Expo Milano 2015.

The USA Pavilion roof has 312 very large panels of SPD-SmartGlass manufactured under license from Research Frontiers by Isoclima, a leading high-end glass manufacturer based in Este, Italy. Each panel measures approximately 1 meter by 3 meters, with a total surface area of over 10,000 square feet, making it the largest smart glass roof in the world. Each panel switches in seconds from dark to clear, or any desired tint in between, in response to an automated control system. USA Pavilion visitors will also be able to instantly control individual panels in the roof from a touchscreen tablet.

James Biber, the New York based architect who designed the USA Pavilion, noted that each SPD-SmartGlass panel not only helps the USA Pavilion achieve its sustainable green architectural design objectives, but because of their fast switching speed, each panel can also act as a pixel to display messages in the roof. "We wanted to also give visitors the abilty to control each window in an entire section of the roof using a touch screen. Also, because the control system for the glass allows instant and precise control over all 312 windows in the roof, this allows us to program the roof to achieve maximum energy efficiency based upon time of day, position of the sun, and ambient weather conditions."

At the grand opening ceremony, Joseph M. Harary, President and CEO of Research Frontiers, thanked Research Frontiers licensee Isoclima, which fabricated the SPD-SmartGlass panels for the USA Pavilion, and licensee Hitachi Chemical Co., which manufactured the SPD-Smart light control film inside the panels, for their contribution to the success of the project. "One of the missions of the USA Pavilion is to showcase the United States as a leader in innovation, science and business. Another mission was leading the way with sustainable design. We are proud to be part of helping them achieve both of these objectives in such a visionary way.

SPD-Smart electronically dimmable windows and skylights reduce cooling energy requirements in the summer, and heating energy requirements in the winter, by maintaining a pre-selected ideal level of light and temperature. SPD-SmartGlass also blocks harmful UV rays at all times. By more effectively controlling daylighting, SPD-Smart windows also allow "daylight harvesting," which some independent sources estimate can save 35%-60% on lighting energy. With the growing pressure to reduce the energy use of buildings, many expect it to be a cornerstone of intelligent building design for years to come. Because SPD-SmartGlass can be retrofitted onto existing structures, even existing building stock can benefit from this green technology. This is significant as approximately 61% of all construction projects are retrofit projects, according to the U.S. Green Building Council.

SPD-SmartGlass technology has been selected as the exclusive smart glass for the USA Pavilion. SPD-Smart technology is the only smart glass technology that gives users the ability to instantly and precisely control the level of shading to any point between very dark and clear. This provides exceptional control over solar energy while also adding to user comfort, security, and protecting interiors. Available in glass or plastic, SPD-Smart windows can be controlled manually or automatically, and are currently being used in the automotive, architectural, aircraft and marine industries, and to protect priceless artifacts in museums from damage from visible light.
