A Landmark Facility Upgrades Infrastructure

Washington-Kosciusko Elementary (or W-K for short) has an incredible history in the Southeastern area of MN. Named after George Washington and Tadeusz Kościuszko, a general and engineer close to the former President during the war, the school emanates the personality and past of the area.

Community members in Winona care about the past, present, and future of education. They are progressive in their stance on technology and wanted to consider different approaches for choosing their retrofit of this facility and nearby Jefferson Elementary. They considered geothermal for the impact on economics and payback, electrification of school heating and cooling, and long term system performance and maintenance.

A Design To Last for Decades

By utilizing Darcy’s groundwater enabled geothermal design, the project team was able to maximize heating and cooling capacity in a small land footprint, unobtrusive to students and faculty. Wells are placed in a slim but accessible parcel of land adjacent to the front entrance of the building, between the playgrounds int the back of the facility. This placement will make O&M simple and straightforward in the future.
