HVAC Upgrades at Montclair State University Sprague Library

Project Overview

LAN provided services for Montclair State University to create schematic designs for HVAC upgrades at the school’s three-story, 118,000 sf Sprague Library Building.

A major goal of the project was to tie in new units to the entire campus’ central chilled water system. This would allow better control of the environment through the implementation of new controls for the building management system (BMS). Part of the schematic design included replacement of the existing Indoor Air Handling Unit (AHU) #5 with a new outdoor-grade mounted AHU, with CHW steam coils, 56 new variable air volume (VAV) boxes, multiple supply and return fans, dual enthalpy economizer, and CO2 demand controlled ventilation. On the library’s North Wing, a new single packaged 80-ton cooling capacity RTU and 15 new VAV boxes with reheat coils were installed, making the library more sustainable and efficient.

Other upgrades were added to further improve building HVAC performance, including new hot water finned tube radiation controls, high pressure steam packaged STHX units, freeze protection pumps, and the replacement of one computer room RTU.
