The North Carolina Department of Administration operates several efficient district heating and cooling systems to support a government complex in downtown Raleigh, NC. Several years back, as equipment in that city’s oldest chiller plant exceeded its useful life, the Department developed a vision to improve equipment service access, replace aging equipment, and solve equipment operation issues. The plan became a reality by converting this single level facility into a two level plant with pumps located on the first floor and two 1,100 ton chillers on the second floor.
