Chapter 11: Environmental Performance Of Cross-Laminated Timber

Part 1 Environmental Footprint of CLT – Preliminary Findings In this part, we approximately determine some quantified environmental characteristics of CLT as a construction material, without conducting a full life cycle assessment (LCA). Finding no existing comparative literature on CLT, we attempt several approaches to estimate the footprint of CLT and the comparison to concrete. Using existing LCA data on Canadian glulam as a proxy, we look at the footprint of the material itself compared to the materials in reinforced concrete, and at the material in a mid-rise building compared to concrete. We then modify glulam LCA data to approximate an LCA for a CLT floor section and compare it to a functionally equivalent concrete floor section…
