Case Study

$250,000 in Annual Savings for Southeast Veterans Hospitals with Comprehensive Energy Conservation Solutions

SMI Impact

Total savings in excess of $250,000 per year

Leak repair for improved system health and safety with savings in excess of 4,000,000 gallons of water per year

Estimated 160,590 lbs of steam saved per year with installation of pressure motive pumps and Improved control of perimeter heating units

Estimated savings of $53,661 with condensate heat recovery

Estimated savings of $75,862 with insulation upgrades

Steam Management, Inc. was contracted by an ESCO to design, bid, and execute turnkey installations of multiple ECMs across veterans' hospitals in the Southeast, including locations in Atlanta, Birmingham, Montgomery, Tuscaloosa, and Tuskegee.

Customer

The ESCO wanted to include significant thermal savings for this project.  Our challenge was that the hospital network had an existing steam trap monitoring system with preventative maintenance program. The hospital had also recently installed new pipe and equipment insulation throughout most mechanical spaces.  Steam Management was tasked with finding creative solutions for the ESCO to include in its EPC.

Problems

  • Existing hot water distribution system design did not allow condensate to be returned to the boiler, because the discharge from the domestic hot water heaters is too low to enter the boiler condensate return tank. The result being that the client was either discharging condensate to a drain unnecessarily due to equipment failure or pumping recoverable energy in condensate back to the utility. Additionally, because the existing condensate return pump was not functioning properly, it was running continuously and wasting electricity.

  • Steam pressure is maintained at a level that is not needed for most of the days throughout the year resulting in decreased efficiency

  • Facility has full-time, year-round steam demand for domestic hot water, building heat, and sterilization.

  • Leaking steam distribution piping

  • Uninsulated steam, condensate and HW piping across multiple buildings

  • Condensate Pump System Replacement

  • Steam Piping Insulation

  • Pressure Motive Pump Pressure Regulator

  • Condensate Heat Recovery

  • Digital PRV
