Database (Customised)

Embodied carbon assumptions (Global warming potential (GWP), or kg CO2 eq) for raw materials, transport, and manufacturing are sourced through published Environmental Indicator databases (e.g. BRANZ, EPiC or Building Transparency).

Speckel is agnostic regarding databases, recognising the different methods in each and the inability to compare them against each other. Where specific values and sources are required, such as an EPD or a specific product from a database, customised values are added on a material basis.

To customise a material, select 'Customise Database' and select the material group you want to update. Once selected, options for Name, Source, Embodied Emission Factor and Units are requested. This process is repeated for all materials that are required to be customised.

More materials are available from the following databases, where specific values are preferred. When adopted, these values override the default value set and provide a more accurate system representation. If you have a preferred database, we recommend you access it below or from the original publisher.
