Tremendous Energy and Resource Savings for NCDOT and North Carolinians

The North Carolina Department of Transportation is one of state’s largest government agencies. NCDOT is responsible for maintaining approximately 80,000 miles of roadways and 18,000 bridges and culverts, as well as implementing and managing transportation systems involving railways, aviation, ferries, public transit, bicycles, and pedestrian traffic. It is also one of state’s largest public employers with more than 14,000 employees. As a result of their high work volume, NCDOT utilizes numerous facilities throughout the state.

In 2013, the NCDOT administration and facilities management teams surveyed their Raleigh area facilities and realized that many of the buildings were still using mechanical systems that were 30 years old or older. The antiquated HVAC and control systems were inefficient or even failing, wasting substantial amounts of energy and driving up operational costs. As a result, the teams created a prioritized list of six buildings that needed mechanical upgrades and repairs, including four buildings in the downtown Raleigh Transportation Complex, Raney Building and the Century Center Buildings A and B also in Raleigh. These buildings are primarily used for offices, thus in addition to needing better system efficiency, a consistently comfortable indoor environment is also needed for employees working in those offices. In addition, the Century Center B building houses the NCDOT Data Center, presenting special environmental needs for the high-volume electronics activity in that area of the building.
