A performance contract was completed for the Durham County Detention Facility, meaning a complete replacement of old equipment, in order to heighten energy efficiency and lower energy costs. The detention center was to remain fully operational during the entire process, as to not disrupt comfort levels of the employees or residents.

New chillers, pumps, boilers and air handling unit fans were installed in order to achieve the goal of a more energy efficient facility. The chilled water system was converted from primary/secondary to variable primary flow. The air handling units were converted to a variable speed fan array, which also added to the overall efficiency of the building.
