“Green Up West Union” Geothermal Network Becomes National Case Study

The Building Decarbonization Coalition (BDC), a nonprofit that aligns critical stakeholders to transform the nation’s buildings through clean energy, has released a case study on the West Union Geothermal Network, part of its research on thermal energy networks (TENs).

In 2020, CEDI Senior Energy District Network Coach Joleen Jansen developed GreenUpWestUnion.com as the community’s outreach lead, part of “From Pilot to Prosperity: Economic and sociocultural success for the West Union community geothermal system,” then hosted by Winneshiek Energy District. Joel Zook, then an energy planner at Winneshiek Energy District, and Jansen worked out of City Hall in West Union in 2020-21 to study the unique system on a grant funded by IEDA.
