also regretted that a single processing track was built, limiting their ability to establish parallel control and test conditions. Omega Center for Sustainable Living The Omega Center for Sustainable Living (OCSL) in Rhinebeck, New York, was opened on June 24, 2009. The building was designed by BNIM Architects, working with John Todd Ecological Design as the ecological architects. Designed to be self-sustaining and carbon neutral, the building includes an Eco-machine for water reclamation. The Eco-machine's 4,500-square-foot greenhouse and constructed wetland was designed to recycle about 5 million gallons of wastewater per year through the activity of plants, bacteria, algae, snails, and fungi. In 2010, the Omega Center for Sustainable Living was one of two buildings world-wide to be the first fully certified "living buildings", demonstrably achieving net zero energy usage and net zero wastewater production over a period of a year. George D. Aiken Center, University of Vermont As part of the green redesign of the Aiken Center at the University of Vermont, John Todd Ecological Design, Inc. supported the creation of the Aiken Center Eco Machine between 2006 and 2012. Much of the design work for the water treatment plant was done by Matt Beamas, one of Todd's graduate students, who presented his master's thesis on the work in 2010. In addition to treating all of the wastewater from the Aiken Center, the system provides opportunities for ongoing ecological design research at the school. The wastewater system includes three separate trains, for experimental study of the system's use. The building is considered to be "a national model for green renovation of a campus building". It has been awarded LEED Platinum certification. Recognition Todd's work has inspired people working on the development of closed ecosystems for living in space, as well as on Earth. Todd was profiled in Inventing Modern America (2002), published by the Lemelson-MIT Program for Invention and Innovation, in which the story of the development of his innovative ecological waste treatment systems is highlighted. John Todd was the inaugural winner of the international Buckminster Fuller Challenge in 2008, for his proposal for a Comprehensive Design for a Carbon Neutral World: The Challenge of Appalachia. Todd put forward a program for the reclamation of more than one million acres of damaged land, through soil remediation, forestry, and the development of renewable energy. Other awards that Todd has received include the Chrysler Award for Innovation in Design in 1994,
