Hyatt Regency Princeton is a 323,900-square-foot hotel with 348 rooms. This project replaced the hotel's aging central plant equipment, including chillers, heating boilers and domestic hot water heaters, improving reliability and energy efficiency. Construction was phased over six months from October 2012 through March 2013, allowing the work to be completed without impacting service delivery or guest comfort.

The chilled water plant upgrade consisted of the installation of two 32- ton centrifugal chillers and chilled water pumps. Equipment was selected based on a life cycle cost analysis that considered first cost, refrigeration energy, pump energy, and maintenance costs. Features of the system include:
The heating boiler plant upgrade consisted of the installation of two high-efficiency condensing boilers with stainless steel heat exchangers, modulating burners, and an efficiency as high as 95%. The domestic hot water plant upgrade included the installation of three high-efficiency condensing boilers with stainless steel heat exchangers and modulating burners and an efficiency as high as 98%, along with four insulated hot water storage tanks.
The cost savings realized from these projects include:
