Headquartered in Eindhoven, Netherlands, NXP Semiconductors is a global manufacturer of wafers for microprocessors and microcontrollers. Southland assisted with various engineering studies within the Chandler, Arizona, campus, which feature multiple fabrication and central utility plants. NXP engaged Southland for the project due to a lack of facilities engineering manpower at the site.
Two of the campus' buildings utilized clean steam for humidification purposes. Our team provided an adiabatic humidification study for the building's air handling units which revealed that the existing steam humidification capacity was for the most extreme outdoor conditions. We calculated energy savings and estimated installation costs to recommend a solution that would provide the best payback option.
The Chandler campus utilizes three centralized cooling loops located in two central utility buildings. Our team focuses on optimizing the glycol chilled water (GCHW) loop and chilled water (CHW) plants located within the central utility plant building. The analysis demonstrated the optimization of the GCHW and CHW system, along with a shutdown of the plate and frame heat exchanger, would yield an annual saving of approximately $33,000.
Studies for the Chandler campus demonstrated an extra annual savings of $45,000
Additional studies for the Chandler campus demonstrated an extra annual savings of $45,000, as well as the opportunity to utilize a water reclamation system to consume excess water without installing additional equipment.
