Brand new St. Johns County elementary school “M” completed in time for 2017-18 academic year

Orange Park, FL; Cafeteria Expansion completed in summer 2013; re-pipe of underground chilled and heating hot water system completed in fall of 2018

Totaling 234,490 square feet, the HVAC system was designed to support year-round comfort and energy efficiency, anchored by the installation of (2) 400-ton chillers providing central chilled water capacity.

The air distribution system featured over 230,000 pounds of sheet metal ductwork, (22) Air Handling Units (AHUs), collectively delivering 195,000 CFM of conditioned air throughout the building. To support precise zone control and occupant comfort, the system included (170) Variable Air Volume (VAV) boxes, each integrated with digital controls.

Additionally, the project involved the installation of almost 6,000 linear feet of carbon steel chilled water piping, ensuring efficient hydronic distribution across multiple floors and mechanical zones.

This project demonstrates a complex and large-scale HVAC installation, integrating substantial mechanical infrastructure with advanced controls to meet the demands of a modern, energy-efficient facility.
