Press Release: WESTON^® Donates GreenGrid^® Green Roof Materials to Support Three Colleges Competing in U.S. Department of Energy’s Solar Decathlon

Chicago, IL — Oct. 6, 2005 — Weston Solutions, Inc. (WESTON^®) announced today that it has donated GreenGrid^® products to three universities competing in the U.S. Department of Energy’s Solar Decathlon, to be held Oct. 6 through 16, 2005, in Washington, D.C.

The Solar Decathlon brings 18 college and university teams from around the globe together to compete in designing and building houses that demonstrate a solar lifestyle. Knowing that the homes must be powered by the sun, students look for ways to ensure that their houses are working at the most energy efficient levels.

Cornell University, the University of Texas at Austin, and Washington State University will incorporate WESTON’s GreenGrid^® system, creating easy-to-install green roofs into their solar home designs.

GreenGrid^® technology, unveiled in 2001 by WESTON and American Builders and Contractors Supply Co., Inc. (ABC Supply), offers a flexible, modular design that quickly transforms an unattractive roof into a beautiful, energy-efficient rooftop garden. Modules are composed of recycled plastic and can be placed directly on the roofing membrane of a building, provided structural capacity is present. Due to their insulating properties, green roofs have been shown to reduce heating and cooling costs by 25 to 50 percent. They also significantly slow a building’s heat gain and loss.

“When outside air temperatures reach a level of 95 degrees Fahrenheit, rooftop surface temperatures can be as high as 180 degrees,” said Patrick G. McCann, WESTON’s president and chief executive officer. “By adding a green roof, students will be able to control the temperature in the solar houses with less energy, creating efficiencies beyond many of their competitors. WESTON is proud to contribute to the ingenuity and creativity of these future scientists and environmental engineers. We applaud their efforts.”

WESTON has successfully marketed the GreenGrid^® green roof technology to federal, state and local government groups and private industry throughout the United States. In addition to reduced energy costs, GreenGrid^® systems add natural beauty, reduce stormwater runoff and extend roof life. Check with your state department of environment to learn more about green roof incentives in your area, including LEED^® credit for stormwater runoff, energy, rapidly renewable materials, urban heat island, recycling, and regional materials.
