Option to remove upfront embodied impacts from template/material

Motivation (why we need this feature): There are likely to be an increase in the number of refurbishment projects due to the heightened focus on retrofit of pre-existing buildings. In these scenarios, elements from the pre-existing buildings will be retained and therefore should not be modelled with upfront embodied impacts. However, if the service life of the material is shorter than the service life of the building then this will need to be replaced through the life of the building. An example of this is solar PV panels. Therefore, having an option that allows a template to input with an option to remove initial embodied impacts but to continue to account for future replacement embodied impacts would be useful. This would also provide a cleaner method for accounting for this than entering a negative material item (as currently required) and avoid issues where the service life of materials cannot be extended, or negative quantities for certain measurements cannot be entered into eToolLCD., Which regions need the feature?: Global, Which projects types does the feature support?: Buildings, Infrastructure, Fit Outs, Which ratings systems require the feature?: This would relevant to all rating schemes as this would be dependent on the design of the building. It could be relevant to any global location, depending on how the design team wish to retain or reuse existing elements of buildings.,

It would be useful when reusing materials/templates from a previous structure (i.e., raised access flooring in an office refurbishment), to have an option where a template can be selected which doesn’t account for the initial embodied impacts, but continues to model the impacts of any replacements required during the
service life of the building.
