In partnership with NRCan and Autodesk, Aly Abdelalim has completed an online tool that allows users to visualize performance of buildings modelled in EnergyPlus. So far the tool works with the Canadian reference office buildings. A feature-limited demo can be found here: http://www.sankeydiagramsexperiments.com/demo.html, while the source code can be found here: https://github.com/alyabdelalim/Sankey-Diagrams-Data-Visualization.
