Building
materials production implies, as every resultant product of a given
fabrication process, environmental and energetic costs. Associated
environmental parameters to water consumption -water footprint- and
to carbon dioxide emissions ?carbon footprint- of raw materials and
the transformation processes allow making a first estimation of the
sustainability grade of a given material. However, once in service,
additional environmental and energetic costs are needed for the
maintenance of the thermal comfort, this new factor is called
energetic efficiency. Nevertheless, the costs related to final
disposal of the building materials after their lifetime is not a
negligible factor when the material sustainability is evaluated. In
the present contribution, environmental and energetic data were
collected to estimate the sustainability parameters of traditional
building materials. These indicators were compared against the
particular case of an alternative construction material named
wood-cement. Such material consists in a pre-molded board made of
recycled wood and Portland cement. Wood wastes were provided from the
packaging industry for fruits and vegetables. Energy efficiency was
evaluated against two traditional construction materials: ceramic
brick and concrete. The cost for comfort conditions represented
between 80 and 98% of the total energy cost. Moreover, evaluation of
the cited parameters showed that wood-cement boards are approximated
between 13 and 15 times more efficient than ceramic brick and
concrete walls.
