What is a VendingMiser ™
Press Release March 7, 2003
VendingMiser™ Will Produce Energy Savings of 46%
The Physical Plant Department has been working hard to save energy on the University of Vermont campus. Often it is the small steps that make the biggest difference. Case in point is the introduction of VendingMiser™ to each of the approximately eighty soda machines scattered across campus.
Vending machines run 24-hours a day, seven days a week, with the sole purpose of keeping your drinks cold. Fronts of the machines stay lit to entice buyers. But is anyone buying soda at 4 a.m.? Richard Wolbach, UVM's Energy Management Engineer, heard the successes that other campuses were having with this new technology and tested it out here. "We quickly realized that UVM could save a lot of money and minimize environmental harm by using the vending miser product," said Wolbach. "Machines sit idle late at night and on the weekends. There is no need to have compressors and front lights running non-stop at these times."
Annually, UVM's soda machines consume 299,447 kWh at a cost of $20,961. Installation of VendingMisers™ will reduce the consumption to 161,527 kWh the first year. Over five years, the savings will be $48,275. And, on the environmental side of the equation, one vending miser reduces greenhouse gas emissions by 2,200 pounds of CO2 each year. Multiply that by the eighty VendingMisers™ now on campus and UVM will prevent 176,000 pounds of CO2 . Or to put this figure into perspective, UVM will save the same amount of CO 2 as taking one car off the road for 31 years, or 110 cars off the road for 3½ months.
VendingMiser™ is a trademark of Bayview Technology, Inc. of California. The device works by essentially coupling an on/off switch with a motion sensor. A machine powers up when someone approaches within 25-30 feet of it and then powers down when the surrounding area has been vacant for 15 minutes. Once powered off, the vending miser will monitor the room's temperature and, based on this measurement, will automatically re-power the vending machine at one to three hour intervals to keep sodas chilled at the manufacturer's recommended temperature. Because the machine is running less frequently, the vending miser will save the the bottling vendor money on maintenance and repair fees. The bottling vendor has approved the installation of this device for non-perishable products but does not specifically endorse VendingMiser™.
