A recent Carnegie Mellon University study of PNC Financial Services Group employees provides some fascinating insight into how best to engage employees in energy efficiency measures. In December 2013, PNC installed Plugwise meters, which measure plug load, or the energy drawn by devices from an electrical outlet, at 80 Pittsburgh employees’ workstations. These 80 employees were divided into four groups, each of which received a different amount of information and control. The first group knew they were being monitored but received no information about their energy consumption. The second group received information through an energy dashboard that collected and displayed plug-load data in real time. The third group also had access to the dashboard and could manually turn on and off specific devices through the use of a switchboard. The fourth group had access to the dashboard and could automate when specific devices turned on and off.
