Case Study -
Appleton Civic Center - Appleton, Minnesota
In 1992, the city of Appleton, MN was searching for a new heating and
cooling system for the citys Civic Center. The building, built in
1977, was originally heated with a fuel oil-fired forced air system, and
cooled with rooftop air conditioning units. City officials explored several
heating system options, including a ground source heat pump system (GSHP).
Installing a GSHP system had several important advantages over other heating
and cooling systems. Foremost, says Roman Fidler, Appleton
City Treasurer/Clerk, GSHP systems dont use fossil fuels.
That is good for the environment. According to the Environmental
Protection Agency, GSHP heating and cooling systems are the most environmentally
clean, energy-efficient, and cost-effective space conditioning systems
available.
Geo$ense
Cost Savings were a large factor for the City. We
budgeted $26,000 to heat and cool the Center in 1992 says Fidler.
After installing the ECONAR GSHP system, the heating and cooling
costs for 1992 were actually under $10,000. We paid more initially for
the GSHP system than another furnace would have cost, but the system has
already paid for itself. Within the first eight months of operation, the
city saved over $9,000 in heating and cooling costs."
