Annually the Sustainable Living Center will produce more energy than it will consume, and as more features are added in time, the building will be completely off the grid with respect to electricity, heating, cooling, water and waste.

With an opening celebration scheduled for April 20, the new Sustainable Living Center at Maharishi University of Management will have the distinction of being one of the few net-zero energy buildings in the country, meaning that the building produces as much or more energy than it uses.
"We will be net-zero for energy, including for electricity and for heating and cooling," said sustainable living faculty member Lonnie Gamble. "Many net-zero buildings are net-zero just for electricity."
The building is designed to eventually be completely off the grid, including for water usage and waste treatment, as more funds are available. However, it will initially be connected to the grid, using electricity as needed during extreme weather conditions. At those times when the solar arrays and wind turbine produce more than the building uses, it will feed excess energy into the campus grid for use in other buildings.
Annually the building will produce more energy than it will consume.
The building's 58 solar panels are capable of producing 15 kilowatts, and the 100-foot wind turbine is capable of producing 10 kilowatts. In addition, energy savings result from the use of technologies such as a heat pump and geothermal tubing. Many passive methods of alternative energy also contribute, such as extensive use of daylighting, the use of earth block walls to moderate temperature extremes and insulate, and strategic placement of windows and verandas.
As more funds are raised, more features will be added until the Sustainable Living Center is completely off the grid with respect to electricity, heating, cooling, water, and waste. A rain catchment system will provide water, and there will be on-site sewage treatment.
"Even in this phase of development, the building is one of the best of the current generation of green buildings," Mr. Gamble said.
Eventually the building will be carbon neutral, which entails being completely off the grid.
"Our carbon footprint is much smaller than most new buildings as we used earth block, earth plasters, and many other low-embodied energy and low-carbon materials in construction," Mr. Gamble said.
The building currently qualifies for gold LEED certification, said construction manager Tim Messenger. But the application is being held until the water and waste systems are in place, which will raise the Sustainable Living Center to the highest level of LEED certification, which is platinum.
The opening of the Sustainable Living Center will coincide with the EcoFairfield weekend being organized by students, and also with Earth Day on April 22. An opening celebration and press conference are tentatively scheduled for Friday morning, April 20.
EcoFairfield events will begin Friday afternoon with community service tree planting, and a keynote presentation by Seth Braun on Friday evening on shaping a collective vision for the future of Fairfield.
