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.
