Method & Evidence

AimTo evaluate the carbon footprint of residential concrete structures throughout their life cycle, identifying the most impactful phases.
MethodLife Cycle Assessment (LCA)
ProcedureA process-based LCA was employed to analyze carbon emissions from raw material extraction, through concrete production and construction, to the operational phase and eventual demolition of concrete structures. Case studies of concrete structures in Jordan were used for evaluation.
ContextConstruction industry, residential buildings, concrete structures, Middle East

Variables

IVBuilding design features impacting operational energy use (e.g., insulation levels, window-to-wall ratio, HVAC system efficiency)
DVCarbon footprint (CO2 equivalent emissions) during the operational phase
CVBuilding location, climate, occupancy patterns, structural material (concrete)

Strengths & Limitations

Strengths

  • +Utilizes a comprehensive Life Cycle Assessment (LCA) methodology.
  • +Focuses on a real-world case study in the Middle East.

Limitations

The specific carbon footprint values are tied to the context of Jordan and may not be directly transferable. The accuracy of the LCA depends on the data inputs used.

Reliability & validity

The reliability of the LCA depends on the quality and completeness of the data used for each life cycle stage. Validity is enhanced by using a process-based approach and real-world case studies.

Think critically

How might the findings regarding the operational phase's carbon impact influence the choice between different building typologies or urban planning strategies?
