Nestled among the cornfields of Southeastern Iowa, Maharishi University of Management is not your typical small college. More than 40 years after its founding, this unique campus has become a showcase of sustainability and solar technology.
Maharishi Mahesh Yogi, best known as man who taught meditation to The Beatles, bought the defunct Parsons College campus in Fairfield, Iowa in 1971 and set up an accredited university to teach his philosophy of world peace and enlightenment through meditation. Along with computer science, accounting and BA, MA and PhD programs, the curriculum stresses healthy lifestyles and a healthy environment.
Biology Professor David Fisher launched the nation’s first four year BA program in Sustainable Living at MUM in 2003. The Sustainable Living Department offers courses in solar, wind and other alternative energy systems, water management, permaculture, alternative building techniques, and performance design for the built environment, and their building serves as a hands-on showcase for the technologies they teach. On an annual basis, the building is not only a “net zero” building, but actually produces as much as 40% more energy than it consumes. The excess energy offsets electricity used elsewhere on campus.
Opened in 2012, the Schwartz-Guich Sustainable Living Center at MUM is a showpiece of green building technology. The 6,900 square foot building features sustainable infrastructure including daylighting, a greenhouse and edible landscaping, gardens, rain catchment, earth block and “whole tree” construction and both solar thermal and solar photovoltaic (PV), as well as a wind turbine. The architectural style, known as “Vedic” architecture, marries eastern and western styles and reflects the philosophy of the university, while exceeding LEED platinum standards.
Daniel Chiras PhD is currently a visiting professor at the Sustainable Living Center. Dan serves as the Director of the Evergreen Institute and is author of over 30 books on solar and sustainability topics, including The Natural House, The Solar House, The Homeowner’s Guide to Renewable Energy and many more. Chiras said of the MUM building: “The Sustainable Living Center is one of the greenest—if not the greenest—classroom buildings on a college campus in the world! It’s an extraordinary model of ecological sustainability and an inspiration to those seeking to build a sustainable human future. The building is a pleasure to teach in and a great learning tool for students.”
Solar Features At The SLC:
The Sustainable Living Center sports 12.5 kW of PV panels to provide electricity. The PV panels are grid-tied by two 2.5 kW and one 5 kW SMA Sunny Boy inverters. An Outback 3.6 kW battery based inverter also stores energy in an off-grid battery bank. The solar PV at the Center puts out an average of 16,250 kWh per year.
A drain-back solar water heating system with 750 square feet of evacuated tube solar thermal collectors capture solar energy that is then stored in a 5,000 gallon tank, where it is then pumped through the in-floor heating system. The collectors provide about 30 % of the heating for the building. Additional heat comes from a ground source heat pump, which uses electricity from the solar and wind systems to provide 75,000 BTUs per hour.
In addition to the solar arrays, The Sustainable Living Center features a Bergey XL 10 wind turbine on a 100 foot latticed tower. The estimated annual output is 17,000 kWh, with power production peaking in the winter and spring. This compliments the solar PV, which produces most of its power during the summer months, when wind speeds are typically much lower.
The SLC has an annual energy use of about 30,000 kWh, including lighting, heating and cooling, fresh air circulation office equipment and classrooms, which is already amazingly low for a building of its size.
Not only at the Sustainable Living Center, but across the entire MUM campus, sustainability initiatives are in full effect. In fact, the school achieved a perfect score for sustainable food sourcing and is the first college in the United States to offer an organic, 100% vegetarian menu. The college encourages bicycling and energy efficiency and is currently in the planning stages of a large-scale solar array to offset more of their electrical use with solar energy.
