Bionova is working on an easier way to incorporate existing materials in a study in
future updates (Bionova 2020). When assigning a material in Tally, there is a box
that indicates salvaged material. If this is checked, Tally does not include any
impacts for the material at any life cycle stage. This simplifies the calculations, but
is not indicative of real-world conditions. The impacts of transporting the materials
to the construction site (if they are being salvaged from a different project), any
necessary energy required to repair, refurbish, customize, or otherwise make the
materials fit for purpose, as well as end-of-life impacts should be counted in the
study. However, even with these impacts, it is possible to make significant savings

against an option with 50% and 75% of the envelope saved
