Stahl completed the two-story, 55,000-square-foot Ankeny Kirkendall Public Library in Ankeny, Iowa. Located at 1250 SW District Drive in the Prairie Trail development, the library also houses the city council chambers and a multi-function meeting and conference room suite.
The building features a primary mechanical system based on distributed floor mounted heat pumps fed by a geothermal well field located under the surface of the library’s parking lot. The well field consists of 126 pumps which draw from the earth’s natural and consistent temperature under the surface to heat and cool the space above the earth’s surface.
According to the U.S. Census Bureau, Ankeny is the 10th-fastest growing city in the United States and the city has grown by more than 20,000 residents since 2010. To serve the rapidly growing northern suburb, a bond referendum was passed in May 2017 to fund the new $14 million library.
Construction started in June 2018 and was completed in February 2020.
The new library was designed by OPN Architects and began operating from its new location starting Feb. 3.
