Sustainability of building construction systems depends on their material and energy consumption, and
the consequent environmental impact. Thus, the evaluation of their sustainability requires a wide analysis
that includes these three topics. Material Flow Analysis (MFA) and Life Cycle Assessment (LCA) used
together can offer a full environmental evaluation. For this reason, in this study, five different facade constructive
systems are evaluated with MFA and LCA to compare them from an environmental point of
view. The constructive systems were monitored in an experimental set-up located in Mediterranean continental
climate, registering energy consumptions for summer and winter periods. MFA evaluated their
total material requirement and the ecological rucksack. LCA evaluated their impact on the environment.
The energy parameter considered the embodied energy of the materials and the energy consumption registered
in the experimental set-up. MFA results show the significant quantity of natural resource extraction
required for building which leads to a considerable ecological rucksack. On the other hand, LCA
results show the importance of the operational phase of the building in the overall building energy consumption,
and therefore in the environmental impact.
The work was partially funded by the Spanish government

(COST Action COST TU0802), in collaboration with and the Cityhall
of Puigverd de Lleida. The authors would like to thank the Catalan
Government for the quality accreditation given to their research
groups SUSCAPE and GREA (2009 SGR 545, 2009 SGR 534). Lídia
Rincón would like to thank the University of Lleida for her research
fellowship. |
