The BTI-Greensburg John Deere Dealership Installs Tornado-Resistant Daylighting Systems and Other Sustainable Materials


On May 4, 2009—exactly two years after the devastating tornado—the Estes family opened its new LEED Platinum state-of-the-art facility and showroom. Family members report approximately 50 percent in energy-cost savings.

The story is fascinating, not just because of the Estes family’s commitment to building as green as possible, but that the entire town of Greensburg embraced sustainability in its efforts to build back. Greensburg now boasts more LEED-certified
buildings, per capita, than any place on Earth.
