Life Cycle Assessment in Green Buildings
Research Guide
What is Life Cycle Assessment in Green Buildings?
Life Cycle Assessment (LCA) in green buildings quantifies environmental impacts of buildings from material extraction through construction, operation, demolition, and recycling.
LCA methodologies assess embodied and operational GHG emissions across building life cycles. Khasreen et al. (2009) reviewed LCA applications in buildings, emphasizing its role in the sector (758 citations). Röck et al. (2019) highlighted embodied emissions as a key mitigation challenge (987 citations). Over 10 major reviews exist since 2009.
Why It Matters
LCA guides green building design by identifying hotspots like embodied GHG emissions, enabling 30-50% reductions through material choices (Röck et al., 2019). It informs policies such as EU Taxonomy for sustainable finance by providing standardized impact metrics (Norouzi et al., 2021). Integration with BIM reduces assessment time by 40% while quantifying circular economy benefits like material reuse (Potrč Obrecht et al., 2020; Chen et al., 2023). Real-world applications include LEED certifications and net-zero building mandates.
Key Research Challenges
Embodied Emissions Accounting
Embodied GHG emissions often exceed operational ones, yet data scarcity hinders accurate LCA (Röck et al., 2019). Variability in material inventories leads to 20-50% uncertainty in results. Standardized global databases are needed for reliable assessments.
BIM-LCA Integration Gaps
Linking BIM models to LCA tools requires interoperable data formats, currently limited by software silos (Potrč Obrecht et al., 2020). Systematic reviews show only 15% of studies achieve full integration. Automation of life cycle inventories from BIM remains underdeveloped.
Circular Economy Metrics
LCA struggles to quantify reuse and recycling impacts in construction waste streams (Norouzi et al., 2021). Absolute sustainability thresholds are rarely applied to buildings (Bjørn et al., 2020). Dynamic modeling of end-of-life scenarios needs refinement.
