vending misers
This semester our team has been testing and installing energy misers on our vending machines across campus! These vending misers use motion sensors to power down machines when the area is unoccupied and then power them on again when motion is detected.
After completing our first miser survey, we found a significant reduction in energy use between the two comparing vending machines.
Our machine without the energy miser consumed 11 kWh more on average than the machine with the energy miser. Additionally, the machine with the miser is located in a significantly busier area than that of the machine without the miser.
Harris Lobby (with miser): 2.745 kWh (Clock-120)
Cummings Basement (without miser): 38.03 kWh (Clock 121)
These numbers are the overall equivalent of 803 kWh per year and nearly $225 in annual savings from just one machine!
As the semester continues, we will be going forward with installing vending misers on all vending machines across campus in our efforts to help save energy consumption.
