Iowa Central Community College carpentry program coordinator and instructor Bill McAnally, right, talks to students about an energy-efficient house they were helping to build in Fort Dodge. The project, destined for a housing development near Fort Dodge, was a collaboration between the Iowa Department of Natural Resources, Iowa Central Community College, Iowa State University, RDG Planning and Design and other partners. The house would feature a geothermal heat pump system, windows that maximize solar energy, energy-efficient insulation and even shingles made of recycled materials.
