William Penn University’s $25 million construction project for two individual academic and athletic buildings is the largest and greenest expansion in the private university’s 135-year history. Cunningham Inc. was proud to be a part of the project.

The Oskaloosa, Iowa-based institution’s latest project features geothermal heating-cooling, fabric ductwork, energy recovery ventilators (ERVs), building automation system and other technology, making them two of the greenest campus buildings in the Midwest.

Fabric ductwork by DuctSox, an underground geothermal field system anchored with water source heat pumps by Trane, and Semco ERVs is what makes the 155,000-square-foot Penn Activity Center (PAC) the most efficient building on campus. Our green design helped the university qualify for a $340,700 incentive by local utility MidAmerican Energy. Additionally, the Associated Building Contractors (ABC) of Iowa recently recognized the design with a first place award in its Excellence in HVAC competition.

Fabric duct also helped Cunningham, Inc. solve engineering problems presented by the PAC’s aesthetic gable roof that rises to a 45-foothigh pinnacle. While high ceilings are mandatory for sports activity height clearances, they also necessitate an air distribution system with a high throw capable of reaching the floor. The four 290-foot runs of 48-inch-round TufTex that Vogt specified has 3-inch diameter high throw orifices running the entire length, capable of reaching the floor with heat in the winter.

Perhaps the major energy saver on the project is the geothermal system that supplies the ductwork for the PAC and the 55,000- square-foot academic building, the Musco Technology Center (MTC). The PAC’s six 20-ton heat pumps continually receive 55°F water from a geothermal well field that both buildings draw from with two 460-V, 25 hp pumps.
