Mapping the flows of built environment materials

A consistent and comprehensive approach to data collection, analysis and management is fundamental for developing the concept of buildings as material banks at a city scale. To facilitate this and contribute to the optimisation of supply and demand, this area will focus on mapping data which will be used to give an overview of existing materials in the built environment.


The data collection and analysis will facilitate the establishment of ‘buildings as material banks’, where our future building materials come directly from the building stock of our cities today.

This focus area will drive the development of:

  • Key circularity indicators to support how urban planners deliver performance evaluations in a circular built environment;

  • A Materials Exchange Portal - a digital database to optimise supply and demand.

Below are the latest outcomes and outputs in this focus area
