Platte Fifteen Life Cycle Assessment
LCA study compares embodied carbon, construction costs, and construction speed of a real mass timber office project with functionality equivalent buildings in steel and concrete.
Carbon
Calculating the Carbon Stored in Wood Products
There are many complex elements associated with carbon accounting and life cycle assessment (LCA). Fortunately, the amount of carbon stored in wood is a straightforward calculation that remains consistent for each wood species.
