Embodied Carbon Intensity Diagrams

Included on this page are embodied carbon intensity diagrams for some typical framing schemes for various building use types. The diagrams only account for floor framing of interior bays and do not account for vertical elements such as columns or bearing walls.  The main intent of these diagrams is educational and to provide a range of embodied carbon values unique to the bay geometry chosen to inform the practicing structural engineer of embodied carbon intensity for framing schemes considered typical.  These could also be used as a way to back check your own assessments or even as a general guide for early design embodied carbon estimates.

Multiple structural engineers and life-cycle assessment professionals were engaged to independently design and assess each framing bay.  The diagrams show a range of structural material quantities and embodied carbon impacts.  The life-cycle assessment values were calculated using three commercially available life-cycle assessment software packages.  Refer to the embodied carbon intensity diagram primer for additional information.
