In 2013, iCons 2 Energy students did something no one has ever done before - they created energy flow diagrams (EFDs) for the UMass Amherst campus. Five teams compiled energy use data from the entire campus, and each created a diagram to represent how energy is used on campus. Being able to visualize campus energy use has big implications for our allocation of resources to efficiency improvements. This project would not have been possible without the collaboration of the UMass Sustainability Initiative, so we want to offer a heartfelt thanks for their support in putting the EFDs together and hope we can collaborate in the future.
