Life Cycle Assessment (LCA) in Earth Construction: A Systematic Literature Review Considering Five Construction Techniques

In the past decade, there has been an increase in environmental performance assessment earth construction through life cycle (LCA) methodology. A Systematic Literature Review verified LCA methodology trends of five techniques from 2016 to April 2022, resulting 27 studies. The results have analyzed qualitative thematic analysis, considering Considering embodied carbon (GWP) and energy, transportation binder content were main factors that influenced performance. Hence, earth-based constructions exhibit better different impact categories than conventional materials. Environmental guidelines technical features presented studies are discussed for Adobe, Cob, Rammed Earth (RE), Compressed Block (CEB), Light Straw Clay (LSC). This study presents benchmarks at unit, wall, building scales aiming encourage applied fostering discussion sustainability.
