. 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 … ecological rucksack. LCA evaluated their impact on the environment. The energy parameter considered the embodied energy of the …
