Oswego Police Department

Oswego, Illinois

Henneman Engineering provided design engineering services for a new 70,000-square-foot police headquarters for the Village of Oswego, Illinois. The new building accommodates the operational needs of a progressive municipal police department as it serves a growing community. The facility houses all police department functions, including a jail, indoor firing range, evidence laboratory, and offices as well as a community center and gym/locker rooms. The building was designed with sustainability features with the goal of achieving LEED Silver certification.

Henneman provided mechanical, electrical, plumbing, fire protection, and Information Technology design services on this project. Cooling is provided with high-efficiency magnetic-bearing air–cooled chillers. Heating is via high-efficiency condensing boilers supplemented by a solar hot-water system utilizing high-efficiency evacuated-tube solar hot-water thermal collectors acting as the walls of the tower. Roof-mounted and indoor air-handling units with energy recovery wheels serve a variable air volume distribution system. The firing range AHU includes three levels of filtration on both supply and exhaust. Radiant floor heat is provided in the entry and lobby areas. The lighting is high-efficiency LED; daylight harvesting allows the reduction of lighting levels during the day.  Domestic hot water is generated with condensing-type hot water heaters. Low-flow plumbing fixtures with electronic controls minimize water consumption. 

Henneman also performed the energy modeling in support of the LEED certification. We predicted to reduce energy consumption of the building by 24% as compared to the code-defined baseline. 

Because the building acts as an emergency operation center (central command and control during disasters and emergencies), certain areas of the building are 100% backed-up by the 500 kW diesel generator with fuel oil to operate for 24 hours. In addition, the electrical system is designed with an exterior electrical connection that allows a 1,500 kW  truck-mounted generator to provide backup of the entire facility should it become necessary.
