unitary elements is created, whether they are machinery or material, and conversion
factors are applied to them according to their nature, thus obtaining the basic WF of
each element. An example is taken from each family of materials in Table 11.
Based on the quantification of the initial scenario (S1), the input and output
volumes of each of the scenarios described have been evaluated, obtaining the input
and output flows of each system in terms of total volumes for an average year together
with the quantification of the water footprint components Table 12.
The WFBs will be part of the database of the construction information system
and will be incorporated at the base of the pyramid in the price structure. Thus, in
