Penn State York – Main Classroom Building HVAC System Replacement

Precis was tasked with the design-build project for Penn State York to completely upgrade the HVAC and associated building components for the 30,000-sf, three-story Main Classroom Building. The project was partially funded by the university’s energy savings program.

Mechanical system modifications included replacement of the existing constant volume air-handling units, electric reheat coils, and electric perimeter finned-tube with new variable volume air-handling units, terminal units with hydronic reheat coils, and hydronic perimeter finned-tube using heating hot water from a new condensing boiler, pumps, and distribution piping. The project included replacement of the existing water-cooled chiller and chilled water and condenser water pumps and an upgrade from constant to variable speed. All air devices were replaced with selective re-use of existing ductwork distribution. New direct digital controls (DDC) were provided throughout. All fluorescent lighting was replaced with LED lighting. Replacement of all ceiling grid and tiles, selective wall painting, and selective flooring and storefront replacements were included.
