What is this graphic showing? Describe the different parts of the graphic and how it communicates the data.

To solve big problems, we need to ask bold questions. Passive House design offers a powerful answer by delivering significant reductions in energy demand. At the end of 2022, Massachusetts enacted the Specialized Opt-in Code, which municipalities can adopt through a local voting process. This code requires Passive House certification for multi-family buildings over 12,000 sf. The map shows a clear correlation between the adoption of this more stringent energy code and a rise in Passive House projects following 2022.

What type of graphic is this?

  • Animated gif

Design Variables

  • Passive strategies

What tools did you use to create the graphic?

  • Adobe Photoshop
  • Javascript
  • Python

What was successful and/or unique about the graphic in how it communicates information?

By animating the evolution of Massachusetts’ energy code map alongside the emergence of Passive House projects, we create a compelling visual story that allows readers to see the connection to their own communities and built environment. The graphic connects policy makers who think in larger municipal scales, to architects, who think at the project level.
