Add materials to a project

Last updated January 10, 2014


This guideline explains how to fill the "Add material" form on Shaped.


Read the pop-up instructions in front of each field.

Enter entire numbers, no decimals.

% are numbers between 0-100.

The form is preloaded with default values. To entre YOUR values, click the (+) buttons and edit/fill the grey fields.


Indicate the quantity of material entering the site. Note that it is usually different from the quantity of material actually installed on the project (account for construction waste).


Enter 1 if the material is only used on this project. Enter 2 (or more) if the material is salvaged or anticipated to be reused after deconstruction of the project.


Service life:
Indicate the service life of the material under normal conditions of use and weather exposure. Do not take into account obsolescence due to consumers changing tastes and preferences. Results from tests done in accordance with recognized methodologies such as ISO, ASTM, etc. are preferred.


Cradle-to-gate emissions:
Indicate the cradle-to-gate emission factor of the material assessed in accordance with PAS 2050-2011 (free download at


Do not account for stored carbon here. If the material includes components eligible for carbon storage such as wood, sheep wool, etc. report that in the “carbon storage” section (see below).

Do not consider carbon offsets (PAS 2050, 5.8).


The method adopted for accounting for recycled input is the method known as “100-0”. Include all emissions associated with recycled input. If the material includes recycled content such as recycled steel, fly-ash, etc. add the corresponding recycling emissions (incl. transport) to the emissions of the new material.


The total % landfill+incineration+recycled must be 100%.


Carbon storage:
Only biogenic components such as wood, sheep wool, etc. and components such as cement able to absorb atmospheric CO2 via recarbonation are eligible for carbon storage. Carbon feedstock of fossilized origin (as in plastics for example) is excluded. For wood/biomass, only wood originating from "well-managed" forests (FSC, PEFC, or equivalent) and biomass waste are eligible.
