Overview

The city of Greensburg, Kansas, is rebuilding as a model green community with the help of the U.S. Department of Energy and its National Renewable Energy Laboratory. A tornado destroyed or damaged 95% of the town's homes and businesses on May 4, 2007. Greensburg turned disaster into opportunity and created a vision to rebuild as a sustainable community. The town has gathered a diverse group of experts, including DOE and NREL, to make their vision of rebuilding green a reality. This brochure highlights the energy-efficiency and renewable energy features of this new school building in Greensburg, Kansas.  Technologies include Wind Power and Ground Source heat pumps, helping to meet the goals of Energy Efficiency and Water Conservation.  The technologies include bringing the right people together, create a vision, evaluate options and determine the feasibility, and develop the goals of the project.
