Marrying historic preservation with sustainable building isn’t new to Iowa’s main streets. The town of Woodbine (population 1,564) [from 2010 census] in western Iowa recently rehabbed 23 storefronts in its historic three-block Main Street district (top). In northeast Iowa 60 historic structures in downtown West Union are in the process of reconstruction. The project most resembling Green & Main is the recently completed rehab of the Valley Junction City Hall (winner of Preservation Iowa’s 2011 Sustainability in Preservation Award) in West Des Moines. It includes a menu of sustainable technologies, including geothermal heating and cooling, energy-efficient lighting, solar roof panels, a green roof, water-conserving fixtures, and salvaged and recycled materials.
