Visualization of the Week: Urban metabolism

Visualizing cities' energy usage, population density, and material intensity.

This week’s visualization comes from PhD candidates David Quinn and Daniel Wiesmann, who’ve built an interactive web-mapping tool that lets you explore the “urban metabolism” of major U.S. cities. The map includes data about cities’ and neighborhoods’ energy usage (kilowatt per hour per person) and material intensity (kilo per person) patterns. You can also view population density.

Quinn writes that “one of the objectives of this work is to share the results of our analysis. We would like to help provide better urban data to researchers.” The map allows users to analyze information on the screen, draw out an area to analyze, compare multiple areas, and generate a report (downloadable as a PDF) with more details, including information about the specific data sources.

Quinn is a graduate student at MIT; Wiesmann is a PhD candidate at the Instituto Superior TĂ©cnico in Lisbon, Portugal.
