Life Cycle Assessment of Precast Concrete Commercial Buildings: Cradle-to-grave – Summary of Concrete Finding

 

In order to better understand concrete’s environmental performance in the context of building construction, use and end-of-life, a life cycle assessment (LCA) of a typical commercial building with variations of building envelope and three variations of structural framing in two Canadian locations was conducted.

The building types were modeled in two cities representing two Canadian climates: Vancouver, British Columbia—a cool climate (Climate Zone 5C)—and Toronto, Ontario—a cold climate (Climate Zone 6A). This LCA study (1) was a cradle-to-grave LCA, done in accordance with ISO standards. Since the LCA included a comparative assertion intended to be disclosed to the public, an independent external committee of LCA and technical experts critically reviewed the methodology and results.
