Platte Fifteen Life Cycle Assessment
Case Study

We are excited to share with your our recently published Platte 15 Life Cycle Assessment Case Study on behalf of Thinkwood and Woodworks, which illustrates the embodied carbon benefits of mass timber construction and it’s relationship to construction costs.

KL&A has dedicated ourselves to understanding the environmental impacts of our structures and materials and incorporating this into our design practice. We are now capable of performing Structural Life Cycle Assessment and can aid in initial system and material selection to address embodied carbon, among other services. 

The full case study can be found here.

Global CO₂ Emissions by Sector

CO2 Global Emissions by Sector with MEP

...and what role does structure play?

The following chart shows that global CO2 emissions for the core and shell (foundations, superstructure, enclosure) are 11% of the total.  Total global CO2 emissions are expected to be 40 Gt (1 Gt = 1 billion metric tons), so the core and shell represent about 4.4 Gt of annual global CO2 emissions.  “Other Building Materials” represents the 4.0 Gt in the MEP, Civil, Interiors and Construction components.

Carbon Leadership Forum.  Data Sources: 2019 Global Status Report, Global Alliance for Building and Construction (GABC) and Architecture 2030

Of the 21% of global CO2 embodied carbon of new buildings, comprised of core and shell and other building materials, structure makes up 6%. 

How do buildings fit into the big picture?
