Goal: find as much information as you can on the use of the 11 construction and/or 12 biomass materials and add those to the sublayers of 3.3. Use with the usual upload and tagging procedure.


For the majority of the construction materials, their use likely takes place for buildings, but be sure to also think about their use in other urban infrastructure such as roads, bridges, tunnels etc. Try to find the amounts that are related to the use of construction materials, such as for building new infrastructure or for renovation activities.

  • Amount of new (planned) buildings (in number and square metres), also per typology ideally
    • building permits requested from the city are a good measure for that;
  • Material composition per new infrastructure (building and others) typology
    • For buildings and infrastructure, the bill of quantities or architectural plans could be very relevant. A city typically owns or builds many buildings and infrastructure, so they should have this type of data stored.
  • Amount of new roads (linear metres)
  • Renovation and maintenance amounts / rates (light and deep) (numbers and square metres), also per typology ideally
    • Those can be based on permits, or urban planning plans
    • Try to find those for construction of buildings and roads

Every city is using biomass materials, so there will definitely be data on use and consumption of those for your city too. Since most materials are related to food, this should be a good place to start overall. In addition, remember that there are also materials on garden&park materials, as well as timber products. The following points are a good place to start.

  • Numbers of meals per restaurant (with perhaps the contents of a typical meal), education and health facilities, private canteens etc.
  • Average food consumption in households as well as in restaurants; could be found as part of a typical national diet with data from e.g. food guides.
  • Household budget survey (how much is spent per food items, but also plants or furniture)

  • Consumption and use of materials
  • Central part of the flow diagram, in between manufacturing and wholesale, and waste collection
  • You start consuming when you eat food or use biomass in another way
  • Consider all different places where people consume food and use biomass
  • Goal: Find all those places and then add them up
  • M2:22, Examples
    • Consumption in Madrid, source
  • Household budget survey (HBS);
  • M9:34, other sources: studies done for your city, academic papers;
