In November 2014, there were 66 vending machines across the University estate. This project installed power saving devices to each of these vending machines, replicating a similar project completed by the Natural Environment Research Council at the National Oceanography Centre. These devices reduce the energy consumption of vending machines by switching off lighting and reducing cooling during periods of low use.
This project has resulted in an annual saving of 32,000kWh, £3,200 and 17 tonnes/CO 2 .
