LCA ANALYSIS

As anticipated, steel and metals play a major role on the primary emissions on our construction. It is though a recyclable material that could be reused in the end of its life time. Other villains, as the ready-mix and pre-cast concrete, although having proportionally less emissions, are hardly recycled and that influences its lifetime emissions. Important to notice that gypsum and glasses, although having much less volume in comparison, have significant emissions and are hardly recycled.

Possible Opportunities For Better Performance

As shown clearly in Table 10, Steel and Concrete are the main contributors to our emissions results. Possible opportunities for enhancing the performance include using steel with higher degrees of recycled materials and using concrete with higher degrees of recycled binder and aggregates. This though, may have limited impact due to the structural resistance requirements and the loss of performance we have when using recycled concrete.

Other solutions may include only big design modifications, like using timber structures (which also may have legislation limitations for this use).
