utiliVisor Monitoring Identifies Energy Saving Measures
Building Energy Monitoring For Premier Owner
Hartz Mountain Industries is one of the largest privately held real estate owners/developers in the United States, owns and operates 707 Broad Street, located in Newark, New Jersey. This 519,600 sq ft building was built in 1920 but renovated in 1989.
Supplemental Cooling at 707 Broad Street 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.
Energy Saving Opportunities
After the installation of utiliVisor, the operations center tracked and monitored plant performance at several different seasonal loads. The following items were discovered;
- Malfunctioning Economizer valves were forcing the Air Handling Unit Compressors to operate all year round.
- Improper Cooling Tower sequencing
- The condenser water was not being controlled at the lowest achievable temperature through all seasons of operation.
Through a comprehensive program of building energy monitoring, utiliVisor was able to show the cost benefit of replacing any malfunctioning economizer valves the building had. By doing this, free cooling hours were taken advantage of by no longer operating compressors during the winter months. Reducing the condenser water supply temperature resulted in 5-10% savings (per each degree lowered) at the compressor.
utiliVisor’s recommendations proved effective with cost savings to date totaling almost $62,000 and a 19% reduction in electrical consumption (kWh).
