Want to quickly find the embodied carbon order of magnitude of your project or framing scheme??  Use this very simple estimator.  We call it ECOM.

ECOM, (E)mbodied (C)arbon rough (O)rder of (M)agnitude, is a basic embodied carbon estimator that allows users to determine approximate estimates of what assemblies contribute to a project’s embodied carbon.

The underlying data has been gathered from publicly available Industry Average Environmental Product Declarations (EPD’s) that are applicable to North America. In most cases they are the EPD’s produced by the applicable trade organization and constitute Life-Cycle Assessment modules A1 toA3.

The overarching intent with this estimator is to provide structural engineers or architects an approachable way to estimate embodied carbon.  The estimator is applicable to users of all experience levels and could be used to develop an early project ROM of embodied carbon or it could be used to back check results of a more robust analysis or something in between.

The estimator does not consider important variables associated with life cycle material impact data and is not intended to replace commercially available Life-Cycle Assessment or material procurement tools and calculators readily available.

Simply input the quantity of materials to get the embodied carbon impact.
