Methodology, research, and the problems we're solving.
The real sources, weights, and thresholds behind retrofit priority and air quality, and how the results actually distribute.
Urban climateAdministrative boundaries are the wrong unit for describing urban heat. Here's what happens when you use them anyway, and why the field moved on.
ComplianceA new disclosure standard asks for building-level physical risk data most companies have no way to produce.
San FranciscoThe city's own retrofit ordinance names which buildings are soft-story risks. Here's how that real compliance list becomes a per-building score.
San FranciscoA real modelled rupture, real intensity zones, and a real scaling mistake we found and fixed while turning it into a score.
San FranciscoMost of our pilot city has to estimate height from floor counts. San Francisco publishes a real LIDAR measurement for every building instead.
