11 Commercial Buildings Efficiency Results Thirteen Greensburg buildings are saving a combined total of $200,000 in energy costs per year
12 Commercial Buildings: Proof in the Energy Bills
13 Saving Energy: First Community in U.S. to Have (Mostly) All LED Streetlights 40% more energy efficient 70% less operating costs
14 Using Utility-Scale Renewable Energy: Greensburg Wind Farm Class 5: 7.8 mps at 50 meters 9.1 mps at 85 meters 12.5 MW (ten 1.25 Suzlon turbines) About 4,000 homes Kansas Power Pool is the purchaser Greensburg receives the renewable energy credits for their usage Funding through USDA, John Deere Renewables, and Native Energy
15 Using Distributed Renewable Energy Several ground source heat pumps on commercial and residential buildings Photovoltaics on four buildings 50-kw wind turbines at school, hospital (two), John Deere, and Best Western Drilling geothermal wells at the Courthouse 2 kW Photovoltaics for GreenTown Eco-Silo Home 7 kW Photovoltaics (roof, top right) on Sunchips Business Incubator
16 Making Change Last: City Policies Completed City RE policies Interconnection agreement Net billing policy Wind ordinance Solar ordinance Detailed white paper on wind turbines in residential areas Green Building Program MOU with Kansas chapter of National Association of Home Builders Training for Green Building Professionals held Nov 4-6, 2009 in Wichita; two Greensburg representatives attended NAHB offered to train two Certified Raters to work in the area Adoption of energy-efficient building codes (IECC 2009) – nope.
