Abstract


Opportunities of considering time in LCA studies are shown through our
“dynamic” system and impact modeling of different domestic hot water
systems. Our “dynamic” carbon footprint modeling changed the conclusion
of the equivalent “non-dynamic” evaluation which shows that temporal
consideration might provide a more representative assessment. The
temporally characterized distributions of elementary flows we used also
bring new analysis opportunities for practitioners. As an example, we
believe that such information will enable the simple identification of
products with high potential for future environmental improvement.
Describing the temporal distributions of natural resource extraction could be
another opportunity for dynamic modeling as they would provide valuable
information on when and how consumption could be an issue.
