Project Motivation

So you know how we always talk about saving energy and being more green about our electricity use here on campus? Well, it’s always hard to know how to make an actual impact. For instance, to get a good sense of where to focus our sustainability efforts, we might like to know:

  • 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?

Luckily, our web app that makes answering all of these questions easy! Building Services has made a lot of campus energy data available to the public, but before this app, there was no way to find it in an accessible, useful, and visually interesting format. Now, with our app, you can easily find detailed and up-to-date energy information for buildings on campus!


Select a building

Detailed energy information populates the sidebar.

Sidebar Graph

Hover over the line to see energy level at a given time. Select a date range on the bottom graph to focus on a subset of the data.

Select data interval

The main data interval selector allows you to view data over the past day, week, or month. This updates both the sidebar graph date ranges as well as the timeline range (more details below).

Play back Historical Energy Map

Play back the historical energy map over the selected time range to see the map colors update as energy levels of buildings change over time.

Select buildings by groups

Only buildings within the selected group are colored and selectable. The sidebar graph populates with cumulative energy data for the group of buildings. In addition, the color scale in the legend updates based on the group selected.

Other Features

  • Zoom on the map by hovering over the area to focus in on. Then scroll, double click, or pinch zoom in.
  • Laptop and House energy comparisons are based on this measure: laptop = 17W, house = 1.245kW.


As with any project that uses data, this project is subject to the limitations and inconsistencies in the original data sources. The most notable limitation is simply the lack of data feeds for many buildings on campus. Not to mention, the original data feeds occasionally go down for hours or days, or display unrealistically large or small (even negative) values. We have done our best to clean up the data before it reaches the client, but these fundamental issues make it somewhat difficult to provide complete or reliable information. But in spite of these limitations, we think this project is still useful for providing quick snapshots of campus energy use and showing trends over time.
