the development of processes (reports, flowcharts, methodology, etc.), consistency,
references and standing out for the fact that it merges data from several databases
of the construction industry (Martínez-Rocamora, Solís-Guzmán, [47]. From this
database, a series of “environmental families” have been obtained which will be
responsible for assigning to each BP their corresponding impact basic according to
their similarity.
Of the life cycle inventory for each of the materials, the reference used for calculating indirect WF is that disseminated by the Water Footprint Network (WFN),
whose Hoekstra [38] concept and calculation methodology “The Standard Calculation Methodology” and “The Water Footprint Assessment Manual” (A. Y. Hoekstra,
Chapagain, Aldaya, & Mekonnen, 2011). To then calculate the direct and indirect
consumption of any productive process expressed in volume of water consumed
(m
3 /Kg) (Fig. 11, Eq. 30).
