This document describes Open Energy, a project that aims to develop a platform to visualize energy systems in real-time. The project seeks to increase understanding of how energy systems work through new interfaces. It prototypes an open source energy infrastructure as envisioned by the Third Industrial Revolution. An energy monitoring device collects real-time data on consumption from various electrical variables, which a visualization system displays through experimental interfaces to amplify energy awareness. The interfaces show energy behavior in housing environments and explore spatial data visualization and augmented reality.
