Live Energy Heatmap of Campus

campus heat map Princeton Energy Heat Map

Princeton students, Adam Gallagher '16, Josh Bocarsly '15 and Annie Lu '17 created a live energy heatmap of campus for the course COS 333: Advanced Programming Techniques. Using campus energy data from Facilities, they were able to visualize detailed and up-to-date energy information to answer questions such as:

  • Which building uses the most electricity on campus?
  • Do the dorms use more electricity during the day or at night?
  • What is the impact of buildings like the stadium that see large spikes in energy usage when being used?
