WorkingBuildings provided retro-commissioning services for Navistar’s world headquarters. The systems investigated include HVAC, lighting controls, fire alarm, and emergency power. The work consisted of assessment, testing, and reporting on equipment condition and a master equipment list. Functional performance tests were performed to verify proper operation of mechanical and electrical systems. WorkingBuildings also performed test and balance activities to the existing air handler units to assess the state of the fan systems. The findings led to a full equipment replacement.
