Heating and cooling Cline Library
Modernizing our equipment and commitment to sustainability at NAU
Retrofits and upgrades to Cline Library’s heating and cooling (HVAC) infrastructure began in 2012. These projects were part of the universities commitment to achieve carbon neutrality by 2020.
- Installed energy-saving Variable Frequency Drives (VFDs) on 15 air-handling units throughout the building.
- New monitoring controls installed on 154 heat pumps.
- Replacement of HVAC coils: In May of 2014, HVAC coils in the library were replaced. Approximately 1,200 lbs of coils were recycled as part of this renovation work. The HVAC coils, part of the original phase of building construction installed in 1966, had reached their end of life.
