The federal government built the James A. McClure Federal Building and U.S. Courthouse in 1966 to support the U.S. Courts and other federal agencies. It serves that purpose today. This urban-unique building flanks a historic residential neighborhood, nestled against the Boise foothills, and rests on 8.5 acres that adjoin several park-like acres owned by the Veterans Administration. The nine-floor building contains a mechanical penthouse, with seven stories above grade and a basement below grade.
The building structure includes a framework of steel girders coated with asbestos fireproofing. The exterior facade consists of precast concrete and glass, with a rubber membrane design. A geothermal water system heats the building. The air conditioning consists of two 350 ton chillers, with a free cooling loop added in 1999. Ventilation occurs through constant volume variable temperature mixing boxes with some package units for cooling conference rooms, judge’s chambers, and local area network (LAN) rooms. Building lighting features include fluorescent fixtures that have been retrofitted with parabolic reflectors, T-8 lamps, and electronic ballasts.
