Has the institution installed vending machine motion sensors for at least one vending machine?:

A brief description of the technology used:

Previously, CSU had vending machines on campus with a technology called Vending Miser. This sensor regulated cooling and lighting of the machine when it is not in use. In the summer of 2011 CSU switched to Energy Star machines. In addition to the added benefits of the energy star machines, CSU decided that the lights are generally not needed in most of these machines and they have been removed. These new machines reduce energy use even further than the Vending Misers.

CSU also reduced the total number of machines on campus. The total energy savings from all of these measures (new machines, removed lights, and decreasing the total number of machines) is as follows:

Baseline energy consuption from vending machines = 688,400 kWh/year
After vend misers = 426,500 kWh/yr
After Energy Star machines = 207,100 kWh/yr
After removing lights = 153,600 kWh/yr

So from beginning to end we reduced energy by 78% from baseline.

The percentage of vending machines with sensors:
