Engineering Design Services for Macomb County, Michigan

Mechanical and electrical engineering services were provided for a new 41B District Court building. The courthouse is a two-story building with a full basement and a flat roof, encompassing approximately 67,170 square feet including the basement. The building includes a secure area in the basement for defendants, offices, court support spaces, courtrooms and probation offices.

The mechanical system features consist of a closed-loop hybrid ground source heat pump system and 100% outside energy recovery units located in the basement. All heating and cooling for the building was provided through the heat pumps with some supplemental electric heating devices provided for areas not served by the heat pumps and in some cases to supplement the heat pumps serving areas with large exposures. A closed circuit evaporative cooling tower located on the roof was used to supplement the heat rejection of the ground loop.
