Deep Energy Reduction - Staff Residence

Eagle Bluff completed a Deep Energy Reduction Retrofit in 2011 on the oldest, most energy inefficient building: the Eagle Bluff residence. The goal of the project was to reduce the overall energy consumption of the residence by more than 70% and to offset all the remaining energy use for its operation to achieve carbon neutrality.  A Deep Energy Reduction Retrofit (DERR) is described by Affordable Comfort, Inc. as “a comprehensive sustainable building improvement that offers significantly reduced environmental impact and energy impact while enhancing comfort, indoor environmental quality and durability.”

Eagle Bluff's DERR is the 9th project overall, and the 1st in Minnesota, to officially meet the Thousand Home Challenge, a deep energy reduction initiative of ACI! The goal of the Thousand Home Challenge is to demonstrate the potential to reduce total annual site energy consumption of existing North American homes by 70 percent or more. These reductions are achieved through a combination of energy efficiency, renewable resources, community-based solutions, and behavioral choices.

Alternative Energy Installations

Our 1KW Photovolatic panel and 1KW Bergey Turbine provide enough energy to run our trail lights, entrance sign lights, and charge our golf cart. Any extra energy that is produced is stored in an on-site battery bank.

Water Conservation and Stormwater Abatement

EB's campus sits atop a bluff adjacent to the Root River.  Rain water that falls on capus ultimately end of in the river, to slow erosion we have implemented these conservation and abatement measures:


  • Native Prairie Raingardens: Situated adjacent to the Dining Hall and the Director's Residence these slow the speeed of water as it works it way down the bluff before it makes it to the Root River.
  • Rain Collection Cisterns: These bookend our clasroom building and are used to water the teaching garden.
  • Trail "Speed Bumps"

Food Composting & Recycling

What little food that is wasted in our Dining Hall is either composted in our Vermicomposter (Indoor Worm Composter) or sent to our Compost Greenhouse and added to tumbler composters.  Compost from the worms and tumble is used as an amendment to soil for seedlings grown in our greenhouse or for soil in the raised beds in our teaching garden.  Visit our Teaching Garden page »
