In 2005, Haverhill Elementary was the least energy efficient out of 10 buildings at Southwest Allen County Schools based on cost per square foot. Originally built in 1981 with a traditional central plant, it had a water cooled chiller and inefficient and oversized boilers. The chiller/cooling tower combination was expensive to operate, had outlived its usefulness, and was in dire need of replacement.
After reviewing multiple options from different providers, a unique and innovative geothermal system proposed by Performance Services was clearly the best overall solution. The hybrid design utilizes much of the existing air and water distribution-saving significant dollars. The geothermal system relies on a heat recovery chiller (rather than heat pumps) and a vertical well field for central plant heating and cooling needs.
