We are in the process of rebuilding the OSCAR site. Please check back at the end of September, 2018 for an exciting new site!


OSCAR is an informational resource for appropriate interventions to improve the carbon footprint of your existing building.


OSCAR guides you through the process of designing the sustainability improvements that are most appropriate to your existing (and perhaps historically significant) building. In this process you will:

  • learn about the best practices for each element,
  • discover strategies that may be well-suited for your building and climate, and
  • understand how your building components work together to create a holistic intervention strategy for your whole building.

OSCAR does so by helping you build an informational model of your building, over the course of five steps. At the end you will have a printable report, documenting the decisions you’ve made along the way.

“When we try to pick out anything by itself, we find it hitched to everything else in the Universe.”  -John Muir
