Key Findings

  • 01Base isolation with damping devices (Case 3) was the most effective seismic retrofitting measure.
  • 02Base isolation with damping devices (Case 3) had the lowest overall environmental impact according to LCA.
  • 03Concrete shear-wall strengthening (Case 1) had a moderate environmental impact.
  • 04Reinforced concrete column jacketing with shear-wall strengthening (Case 2) had the highest environmental impact.

Application

Design takeaway

When selecting seismic retrofitting strategies, designers should consider the full environmental impact across the material's lifecycle, not just structural efficacy.

How to apply

When evaluating retrofitting options, conduct a comparative LCA for each potential solution to quantify and compare their environmental footprints.

Project actions

  • 01When choosing materials or methods for your design project, think about where they come from and what happens to them after use.
  • 02Use LCA tools to compare the environmental impact of different design choices.

Method & Evidence

AimTo determine which seismic retrofitting approach for reinforced concrete buildings has the lowest environmental impact throughout its lifecycle.
MethodComparative Life-Cycle Assessment (LCA)
ProcedureThree different seismic retrofitting strategies (concrete shear-wall strengthening, combined column jacketing and shear-wall strengthening, and base isolation with damping devices) were applied to a model building. A Life-Cycle Assessment was conducted for each strategy using the ReCiPe 2016 methodology to evaluate environmental impacts.
ContextSeismic retrofitting of existing reinforced concrete buildings.

Variables

IVType of seismic retrofitting approach (concrete shear-wall, combined jacketing/shear-wall, base isolation with damping)
DVEnvironmental impact (measured by LCA metrics like ReCiPe 2016 midpoint and endpoint scores)
CVBuilding type (five-story reinforced concrete), design era (1970s principles), geographical location (Israel)

Strengths & Limitations

Strengths

  • +Comprehensive comparison of multiple retrofitting strategies.
  • +Application of a recognized LCA methodology (ReCiPe 2016).

Limitations

The complexity of LCA can be a barrier; simplified tools or focusing on key impact categories might be necessary for smaller projects.

Reliability & validity

The study's reliability is supported by the use of a standardized LCA methodology. Validity is enhanced by applying the methods to a specific building context, though generalizability to all building types may be limited.

Think critically

How might the cost-effectiveness of these different retrofitting methods influence their adoption, even if one is environmentally superior?

Design Principles

"Environmental impact should be a primary consideration in the selection of structural retrofitting techniques."

This research provides crucial data for designers and engineers making decisions about building retrofitting. It highlights that the most effective structural solutions are not always the most environmentally responsible, necessitating a holistic approach that considers resource consumption and environmental impact throughout a project's lifecycle.

What This Means for Your Design

When you need to make a building stronger against earthquakes, some ways to do it are better for the environment than others. The study shows that using special 'base isolation' systems is both the best for safety and the best for the planet, compared to just adding more concrete walls.
