Life Cycle Assessment in Sustainable Construction

Life Cycle Assessment (LCA) has become a cornerstone methodology for evaluating the environmental performance of the built environment. By quantifying impacts such as greenhouse-gas emissions, resource depletion and waste generation across all stages—from raw-material extraction, manufacturing and construction through operation and end-of-life—LCA enables practitioners to identify critical hotspots and compare alternative design and material strategies. In the pursuit of net-zero and circular-economy goals, integrated approaches now combine LCA with life-cycle cost analysis and scenario modelling to address uncertainties related to future energy systems, climate trajectories and user behaviours. Digital innovations further streamline inventory data collection, while harmonised impact assessment methods ensure comparability across regions. Globally, this evidence base informs policy frameworks, green building certifications and industry standards, promoting low-carbon materials, adaptive reuse of existing stock and resilient infrastructure solutions.

Research from Nature Portfolio

Recent studies have advanced the integration of LCA with renovation decision-making under uncertainty. One investigation developed robust retrofit strategies for diverse Swiss residential typologies by coupling LCA and life-cycle cost analysis. This work identifies optimal combinations of envelope improvements and heating system replacements, highlighting bio-based insulation’s capacity to balance embodied impacts with operational savings. The approach accommodates future climate, energy-grid and user-behaviour scenarios, ensuring equitable, low-carbon transformations while avoiding initial embodied-carbon spikes.

Technical terms

Life Cycle Assessment (LCA): A structured methodology for quantifying environmental impacts of a product or project over its entire life span, from resource extraction to disposal.

Embodied carbon: The total greenhouse-gas emissions associated with material extraction, fabrication, transport and construction activities before a building enters service.

Operational carbon: Emissions generated during the use phase of a building, primarily from energy consumption for heating, cooling, lighting and equipment.

Life Cycle Cost Analysis (LCCA): An economic evaluation that calculates all costs incurred throughout a building’s life cycle, including initial investment, operation, maintenance and end-of-life expenses.

Building Information Modelling (BIM): A digital representation of physical and functional characteristics of a facility, used to support design, construction and performance assessment, including automated LCA workflows.
