Heifer International works tirelessly to help people in the third world achieve self-reliance through sustainable husbandry and agriculture, so their new Visitor Center in Little Rock needs to be a built example of their green beliefs. To fulfill that dream, Cambridge Seven Associates’ concept for the new "One World Village" creates an educational experience that takes visitors on a trip around the world. That visit connects visitors through recreated villages, interpretive exhibits, and domesticated animals, to daily life for families living in poor rural areas in Guatemala, Ecuador, South Africa, Cameroon, Indonesia, China, India, and Romania. At the heart of C7A’s design is a green central building housing classrooms, a Commons with interactive exhibits, and animal holding facilities, built using sustainable design principles from the indigenous cultures in the exhibits. Natural light for the Commons and natural ventilation for animal holding are provided, with a green roof and standing water adding increased insulation and evaporative cooling. The facility itself will be built with sod construction, hay bail retaining walls, and masonry created on site. Prototypical photovoltaic arrays, small wind vanes, methane converters, and other alternative sources will provide power for special uses and form exhibits in their own right.
