Hartz Mountain Industries, one of the largest privately held real estate owners/developers in the United States, owns and operates 90 Hudson Street, located in Jersey City, New Jersey. This 420,000 sq ft building was completed in 2001 with several Fortune 500 companies as tenants.
Supplemental Cooling at 90 Hudson is provided by water cooled packaged DX Air Handling Units per floor which are fed by a Primary/Secondary Condenser Water system from a plate and frame heat exchanger.
Hartz Mountain Industries has a long history of undertaking projects that boost energy efficiency, and they were looking to partner with a company devoted to cost effective methods to reduce their energy footprint. After the installation of utiliVisor, the operations center tracked and monitored plant performance at several different seasonal loads. After performing a BTU Test onsite and comparing previous utiliVisor data the following items were discovered:
utiliVisor reengineered and commissioned the control sequences for the entire condenser water system including towers, pumps, and heat exchangers. This was all done with only one physical change to the system, which was a new differential pressure transmitter at the bottom of the riser.
utiliVisor’s recommendations proved effective with cost savings to date totaling almost $79,000 and a 10% reduction in electrical consumption (kWh).
