PPG Performance Glazings is finalist for environmental award

Pennsylvania Environmental Council recognizes Solarban 70XL glass

PITTSBURGH, May 10, 2007 – PPG Performance Glazings, a business of PPG Industries (NYSE:PPG), has been named a finalist for the 2007 Western Pennsylvania Environmental Awards in the business category.

The Western Pennsylvania Environmental Awards, sponsored by the Pennsylvania Environmental Council and the Dominion Foundation, recognize and honor outstanding accomplishments in various environmental initiatives throughout western Pennsylvania. Four awards will be presented in the categories of community, higher education, primary/secondary education and business.

PPG was nominated in part for its development of Solarban 70XL solar control, low-emissivity glass. Introduced in 2005 at U.S. Green Building Council’s International GreenBuild Conference, Solarban 70XL glass features an unprecedented combination of solar control and visible light transmittance in a transparent, color-neutral glass.

As the industry’s highest-performing solar control low-e glass, Solarban 70XL glass transmits 64 percent of the sun’s natural light while blocking 73 percent of its solar energy in a standard one-inch insulating glass unit. The resulting light-to-solar gain (LSG) ratio of 2.37 represents a 29-percent performance enhancement over the previous state-of-the-art solar control low-e glass. Even two years after the introduction of Solarban 70XL glass, no other commercial architectural glass has approached its LSG ratio.

As a result of these characteristics, Solarban 70XL glass has demonstrated the potential to generate significant energy savings in commercial buildings where glazing is a major architectural element. According to the U.S. Department of Energy’s most sophisticated modeling software, substituting Solarban 70XL glass for the next-highest-performing solar control low-e glass on a standard glass-walled, eight-story office building in Los Angeles can cut annual energy costs by 6.6 percent, or more than $40,000 per year (based on 2006 energy rates).

Specifying Solarban 70XL glass over its nearest competitor also enables architects and building owners to reduce the cooling capacity and equipment requirements for buildings. According to the same study, the eight-story office building in Los Angeles would require an initial investment in HVAC equipment of nearly $120,000 less if using Solarban 70XL glass instead of the nearest competitive product. The potential savings are even more pronounced when Solarban 70XL glass is compared to other commonly specified solar control low-e and tinted low-e glasses.

Western Pennsylvania Environmental Awards finalists will be recognized at a dinner June 7 at the Westin Convention Center Hotel in Pittsburgh. Each winner will receive a $5,000 donation in their name to the non-profit environmental organization benefiting Western Pennsylvania of their choice. PPG Performance Glazings is one of two finalists in the business category, joining U.S Steel Corp.

PPG is the largest flat glass manufacturer in North America and supplies glass for commercial and residential construction markets, industrial and specialty uses, and automotive, aircraft and other transportation applications.
