Power*e™ Glass News
The 2800 square foot Keystone House located above the Keystone Ski Resort at almost 11,000 feet uses the Power*e™ Glass as its primary sole heat source. Organized into three heating zones, the Power*e™ Glass cost the homeowner less than $95 per month while outside temperatures averaged 27ºF.

DWM reported on the ElectricTV documentary about Power*e™ Glass calling it a greener, more cost effective solution to heat loss through windows. Known as Power*e™ Glass, developed by Radiant Glass Industries of Colorado, the product looks like a traditional double-pane glass window. Between the panes, however, is a conductive coating, over which a safe, low-voltage DC electric current is run, raising the temperature of the inside of the glass pane - and that of the room - and thereby significantly stopping heat loss. According to a study by Kansas State University, a room loses 20 to 50 percent of its heat through the window, meaning traditional HVAC heating is only 75 percent efficient at its best, and 50 percent at its worst. In contrast, the KSU study found that Power*e™ Glass is 85 percent efficient - in addition to stopping 100% of building heat loss through the heated glass - and recent installations have reduced building owner's energy costs by 40 percent.

ElectricTV Produces Independent Documentary about Power*e™ Glass
In August, 2008, ElectricTV.net produced an independent documentary about Power*e™ Glass. In their documentary, they interviewed a radiant heating expert familiar with Power*e™ Glass who believes that it offers substantially better performance than forced air and other radiant heating systems. They also interviewed a customer who is glad that he installed Power*e™ glass several years ago in his restaurant. Finally, the documentary summarizes some of the KSU findings. ElectricTV.net is a joint production of the National Electrical Contractors Association (NECA) and the International Brotherhood of Electrical Workers (IBEW), and is the only web TV program dedicated to reporting the latest developments in the electrical construction and information systems industries.

In July, 2008, Kansas State University conducted additional tests of the Power*e™ Glass comparing its heating capabilities to a natural gas forced air system in a typical Chicago office building. KSU found that the Power*e™ Glass used up to 40% less energy and heated the building more consistently and comfortably than a conventional natural gas forced air system.

RGI installed Power*e™ Glass windows in the glass west wall of a condo located in a high rise condominium overlooking Cheeseman Park, one of the largest city parks in Denver. Operating the Power*e™ Glass at temperatures ranging from 80ºF to 90ºF, the homeowners found that the Power*e™ Glass comfortably heated their entire condo. As a result, they completely turned off their forced air heat and reduced their electric bill by about 40%. Importantly, the homeowners found that the Power*e™ Glass was able to heat rooms on the east side of the condo that do not directly face the glass making their entire condo comfortable.

RGI Receives Patent for its Power-e™ Technology
RGI is pleased to announce that the United States Patent Office issued a patent to RGI for the design and construction of its Power*e™ Glass. This patent recognizes several features of the Power*e™ Glass which contribute to its efficiency, reliability and safety. Other systems simply do offer this combination of unique and now patented benefits and solutions for efficient radiant heating and improved building insulation.

Power*e™ Glass windows were described by KMGH Channel 7 (ABC) as a heating technology "that can actually heat your room and help you save money on your energy bill" in a story that aired on Channel 7 in Denver and nationally on March 28, 2008. The homeowner who had the Power*e™ Glass windows installed in his home said to Channel 7, "A year ago you couldn't even sit in the room without a roaring fire and the heat going." Nobody in his family wanted to sit in the living room, although it had the best mountain views. It was always too cold... now, the furnace in the living room has not turned on once since he installed the new windows. "It's the most popular spot because those two windows are both heated and it's coming from two directions. It is unbelievable, amazing."

RGI Receives Notice of Patent Allowance for its Power*e™ Technology
RGI is pleased to announce that it received a notice of allowance for its patent application for its Power*e™ technology. In issuing this notice, the United States Patent Office indicated that all of RGI's claims are patentable and granted a first action allowance. This represents an important recognition of the uniqueness of the Power*e™ technology and energy saving approach to solving the problem of heating buildings and homes.

This Golden, Colorado home shown in the photo was cold and drafty. Even its three natural gas furnaces could not keep the living areas comfortable. However, by installing Power*e™ Glass windows, the owners are now enjoying their living room and other areas - even when it's 18ºF or colder outside. And much to their surprise, their furnaces now rarely come on! As a result, the homeowners accelerated their remodeling plans to install Power*e™ Glass windows throughout their home.

Dwell on Design Conference 2007
RGI demonstrated its Power*e™ Glass windows at the Dwell on Design Conference in San Francisco from September 14 through September 16, 2007. The Dwell on Design Conference and Exhibition is an idea-driven, hands-on experience designed to ignite a creative spark within anyone who is passionate about modern design, sustainability, and smart growth.

The National Gas Machinery Laboratory of Kansas State University is a leading independent organization regarding the advancement and testing of heating technologies. The NGML tested the Power*e™ Glass windows in August, 2007 to quantify their capability to maintain a constant room temperature of 70°F using the Power*e™ Glass as a heating source when the surrounding outside temperature was 10ºF, 20ºF, 30ºF and 40ºF. Among the findings, the tests confirmed that the Power*e™ Glass windows delivered most of their energy to the interior space almost independent of any inside - outside temperature difference, that the Power*e™ Glass stopped 100% of all other building heat loss through the windows by creating a thermal radiating barrier, and that the Power*e™ Glass windows created a more thermally comfortable occupied space with substantial reductions in energy consumption.

RGI is pleased to announce that after rigorous safety testing, Intertek ETL approved the use of the Power*e™ Glass as a separate heating component. With this second approval, Power*e™ Glass can now be used with any listed low-voltage DC controls and power supplies and can be more easily used with building-wide climate control systems and power supplies.

RGI is pleased to announce that its Power*e™ Glass was selected as a hot new unique product for the 48th Annual Colorado Garden & Home Show in Denver, Colorado. The Power*e™ Glass was described by NBC’s Channel 9 television as “This is radiant. This is new technology for the architectural glass market (residential and commercial). It is an insulated glass with an electrically conductive coating. A safe, low voltage current passes through the glass, quickly providing comfortable radiant heat while stopping cold drafts, condensation and heat loss.”

RGI installed Power*e™ Glass windows in offices in the Colorado State Historical Mansion, the Grant-Humphreys Mansion. The Grant-Humphreys Mansion is located next to the Governor’s Mansion in Denver, Colorado. The State of Colorado was faced with the dilemma of preserving the historic appearance of the Grant-Humphreys Mansion while overcoming heating and cooling problems from a poorly designed forced air system. The solution was retrofitting RGI’s Power*e™ Glass into windows and doors to provide zone heating for offices located in the historic Mansion. Key to the Colorado Historical Society's decision, the Power*e™ Glass is cost effective, easy to install and does not change the Mansion’s appearance.

Prime 121 Restaurant is Cherry Creek North's best steakhouse in Denver, Colorado. Prime 121 Restaurant selected RGI's Power*e™ Glass to be installed as the glass front wall of the restaurant's exterior. Using RGI's unique design for moveable glass, Prime 121 Restaurant also intends to incorporate the Power*e™ Glass into panels that open onto a front patio during warmer months. During Denver’s extremely cold 2006 winter, Prime 121 Restaurant found that the Power*e™ Glass was a cost efficient means to provide warmth and comfort to its customers in its front dining room. In fact, the restaurant found it was able to turn off its other heating systems for its front dining room.
