utiliVisor Delivers Customized Energy Solution To A Premier Cancer Hospital

utiliVisor Improves The Energy Efficiency of a Major Cancer Center in NYC

This Premier Cancer Center provides patient care, research and educational programs along with being staffed by the world’s best physicians and scientists. The facilities are constantly renovating and expanding to meet the growing needs of their patients in their fight against cancer.

With a combined total chilled water generation capacity of 23,000 tons, the district energy plant utilizes both Steam and Electric Chillers to produce chilled water to over one million square feet of hospital and research facilities. This private cancer center turned to utiliVisor to help reduce its multi-million dollar energy bill through energy efficiency.

utiliVisor’s Energy Plant Services began implementation at the largest of the plant’s in the district energy system in 2007. utiliVisor has since been expanded to all of the plants in the system as well as the air handling units at the research labs to provide truly “end-to-end” continuous energy oversight.

utiliVisor Implementation

Operating engineers at utiliVisor’s state-of-the-art operations center use the utiliVisor web based plant analysis platform to recommend the most energy efficient operating strategies to the plant staff without sacrificing comfort at the hospital or mission critical research conditions at the labs. utiliVisor engineers’ recommendations to staff at this New York Cancer hospital included:

  • Maximize Free Cooling by adjusting condenser water flows
  • Sequence Chillers based on part load performance and cost
  • Optimize chilled water loop by correcting chilled water flow
  • Reconfigure the hydraulic bypass

utiliVisor’s unique monitoring system offers the most accurate way to measure plant performance. Monitoring enables the Plant staff and utiliVisor to view the energy efficiency of the individual systems and the plant as a whole – justifying energy upgrades with real data and cost calculations.

Upgrades to the District Energy Plant

utiliVisor monitoring justified upgrading systems at the district energy plant using real time consumption and cost data. utiliVisor data analysis enabled the hospital to receive funding through the American Recovery and Reinvestment Act to upgrade it’s:

  • Variable pumping system from a primary-secondary loop
  • Steam Control Panels on its chillers

utiliVisor also secured a $198,000 incentive from NYSERDA for reducing energy consumption by 1.2 million kWh in the first year

The Results

utiliVisor implementation began in the summer of 2007. Since then utiliVisor has achieved considerable energy efficiency improvements, translating to $3.7 million, or about $1 million per year, in verified cost savings.

“My Staff and I use utiliVisor constantly for improving operation of our chilled water plants. The web advisory service provided by utiliVisor is unique and allows us to sustain the savings and identify problems we never knew. utiliVisor was definitely worth our investment and we are looking to expand utiliVisor’s services to other critical systems.”
