Material Tracker
Every material has a thermodynamic history
This tool traces the solar EMERGY embedded in building materials — from geological formation to use and return. You are about to think differently about the stuff buildings are made of.
MATERIAL TRACKER
Every material has a story older than the building and a future longer than our use of it. Select a material to trace its Lagrangian trajectory and EMERGY cost.
Select a material to trace its energy history and Lagrangian trajectory.
Use ▶ Tour to learn what each metric means.
See where these material trajectories move through space — multi-scalar site maps, Critical Zone sections, the geography of Marseille's urban metabolism.
Bring your EMERGY findings to the Boussole — let thermodynamic evidence weigh the political positions. Who decides which materials are used, and at what cost?
