Cross Plains committee presses for clarity on village hall energy choices as geothermal faces $450,000 premium
Summary
Village President Jay Langfeld and the Sustainability Committee asked for clearer, digestible cost and payback information from Focus on Energy and the project architect after geothermal options for the new village hall were shown to add roughly $450,000 in drilling costs.
Village President Jay Langfeld and members of the Village of Cross Plains Sustainability Committee debated whether to include geothermal heating in the village hall and police station project after Focus on Energy'funded analyses showed a large upfront cost increase for geothermal drilling.
Jay Langfeld, the Village President, told the committee he wanted committees to "take the committees up a notch" and help find grant funding and technical options for the village hall, which currently includes a rooftop solar array in the design. "It would be nice if we could get some funding from that," Langfeld said of solar grants, while also flagging the construction documents are expected in August.
Why it matters: the choice between geothermal and conventional heating affects the project's upfront budget, expected energy use, and potential rebate amounts through Focus on Energy. Committee members said the available packet and analysis were confusing on a key point: one Focus on Energy payback table (agenda packet page 11) lists a 10-year payback for geothermal but does not appear to include the roughly $450,000 additional drilling cost that project planners have cited elsewhere.
Committee discussion focused on three points: the incremental $450,000 drilling cost for the geothermal loops, how Focus on Energy'recommended "bundles" (levels of insulation, mechanical efficiency and other measures) affect rebates and payback calculations, and the rooftop solar sizing and cost assumptions in the packet.
"That page 11 is incorrect," one committee member said, noting the table's payback numbers seemingly omit the incremental drilling cost; another member said she was "willing to use my tax money" for long-term efficiency but asked for clear numbers. Members repeatedly asked for a simple, authoritative explanation of the options and their lifecycle costs.
What the committee asked for: staff was directed to request a concise briefing from Focus on Energy (committee members identified Joe Kadowitz as the county contact) and from Wold Architects (the project designer) that would: 1) explain the three Focus on Energy bundles and the tradeoffs in incremental cost and rebate, 2) confirm whether the packet's payback tables include the $450,000 geothermal incremental cost, and 3) correct or explain the rooftop-solar cost figures in the packet.
Next steps: the committee asked that the village board receive the same digestible analysis so board members can take a clear vote on whether to include geothermal, choose a different energy bundle, or prioritize a larger solar array. In the interim the committee suggested pursuing grants to offset the cost and, if geothermal is not pursued, selecting a higher-efficiency insulation/RTU bundle as an alternative.
"If the geothermal doesn't happen, let's go with the more insulation, etc., plan," one member said.
Ending: staff committed to contact Focus on Energy and Wold for a short presentation for the committee and the village board; the committee will review those materials at an upcoming meeting and then recommend whether the board should vote to direct a specific energy approach.
