Assess learners' ability to apply life cycle assessment (LCA) methods to select low‑carbon building materials for mid‑rise construction projects. Scope includes defining a functional unit and system boundaries; comparing embodied carbon across life cycle stages (A1–A5 and relevant B/C modules); choosing data sources and allocation rules; performing basic per‑m2 or per‑functional‑unit calculations; evaluating trade‑offs such as durability, transport, maintenance, and end‑of‑life; using LCA tools/benchmarks to run scenario analyses; and interpreting results to justify material recommendations within project constraints (cost, performance, codes) and to communicate decisions to stakeholders.
