An Energy Savings Initiative at Central Vermont Medical Center (CVMC) is making significant progress due to the commitment of hospital executives, departmental staff and partners Liebert Engineering, Inc., Efficiency Vermont, and Control Technologies to reducing energy consumption across the hospital.
A recent major step in this effort was the installation of a McQuay Templifier, which recovers waste heat from the hospital's chiller system and uses it to provide hot water during the summer months. "The Templifier is a machine that extracts waste heat from chiller condenser water at about 90o F and boosts to useable temperatures in the 140o F range using a heat pump system," explained Gregory Liebert, of Liebert Engineering, Inc., the Vermont-based firm that installed the new system. This technology is expected significantly reduce CVMC's fuel costs and carbon emissions.
Richard Morley, CVMC Vice President of Support Services confirmed that the annual reduction of 73,000 gallons of #2 fuel oil translates to $238,000 in cost savings. "Even when you factor in the expected increase in electrical consumption of 440,000 kWh, an additional $49,000 in electricity expenses CVMC will see a net energy savings of $189,000," he said.
"In addition to the impressive savings that CVMC will see in their energy costs, the Templifier will provide an annual CO2 reduction of 1,050,000 lbs (525 tons) and a lifetime reduction of 7,900 tons," said Tim Perrin, Key Account Manager Efficiency Vermont. "We are very pleased to be working with them to advance a project that is good for their bottom line, while furthering their efforts to be more sustainable."
There are many energy projects currently underway at the hospital. Prior to installation of the Templifier, in the first 18 months of CVMC's Energy Savings Initiative implementation efforts, CVMC was able to trim annual electricity use by 717,000 kilowatt-hours and cut fuel oil consumption by 10,400 gallons each year. Thus far, this initiative has led to a 4.8% reduction in annual energy consumption for hospital operations, slashing carbon emissions by 490 tons of CO2 annually with an expected lifetime reduction of 4,470 tons of CO2.
To achieve this, hospital lighting was replaced with more efficient lighting. In the kitchen and central sterile supply, where nobody is working during the overnight hours the exhaust fans and air handling units are being shut down. Additionally, a hospital-wide effort was undertaken to deploy power management schemes for all desktop PCs and monitors through the purchase and implementation of Altiris Client Management Suite software. This software enables the back-end control of desktop devices and monitors when not in use but still allows for the capability of IT staff to "wake up" the machines when necessary to upload periodic software patches and antivirus updates. Previous IT management policies requested that computers remain on throughout the day and night; now machines are being shut off at least 10 hours per day. Cumulatively, the lighting, kitchen, and PC power management initiatives will result in savings of $95,000 per year.
"I am proud of CVMC's numerous initiatives to make us a green hospital, ranging from composting food waste and recycling to installing the McQuay Templifier," summed up Judy Tartaglia, CVMC President and CEO.
