The Linear Degressive (LD) allocation approach, particularly when adapted for circular economy principles, can effectively guide design decisions by distributing environmental burdens and benefits across multiple life cycles of building components. This resource management research insight is drawn from a 2020 study published in Sustainability. Using Comparative analysis of lca allocation approaches, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for circularity, utilize allocation methods like the Linear Degressive approach that explicitly account for multiple life cycles and incentivize resource efficiency and reuse.

Application
Design takeaway
When designing for circularity, utilize allocation methods like the Linear Degressive approach that explicitly account for multiple life cycles and incentivize resource efficiency and reuse.
How to apply
When conducting an environmental assessment for a design project involving reused or recyclable components, investigate and apply allocation methods that specifically address circularity, such as the Linear Degressive approach.
Project actions
- 01When assessing the environmental impact of your design, consider how you will allocate impacts across different life stages (e.g., manufacturing, use, end-of-life, reuse).
- 02Explore different LCA allocation methods to understand how they influence your results and design choices.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Directly addresses the challenge of LCA in circular economy contexts.
- +Compares multiple established and novel allocation methods.
- +Applies the methods to practical examples of circular building components.
Limitations
The chosen LCA allocation method might not perfectly capture all nuances of a specific circular economy model. The availability and quality of data for each life cycle stage can also be a limitation.
Reliability & validity
The reliability of the findings depends on the consistency of the LCA data used. Validity is enhanced by comparing multiple established methods and applying them to concrete examples, though the novelty of the CE LD approach may require further validation.
Think critically
How might the choice of LCA allocation method influence the perceived 'circularity' of a product, and what are the potential consequences for design innovation and market adoption?
Design Principles
"Environmental impacts should be allocated across all life cycles of a product or component to accurately reflect its circularity and guide sustainable design decisions."
Understanding how to allocate environmental impacts across various life cycles is crucial for designing truly circular systems. Different allocation methods can lead to significantly different environmental performance profiles, influencing which circular strategies are prioritized and adopted by the industry.
What This Means for Your Design
When figuring out the environmental impact of something that can be used again or recycled, how you 'share' the impact across its different lives matters a lot. A specific method called the Linear Degressive approach helps show which designs are better for the environment when they are reused or recycled.
How to use in your project
- 1.Reference this study when discussing the methodology for Life Cycle Assessment (LCA) in your design project, particularly when evaluating the environmental impact of components designed for reuse or recycling.
- 2.Use the findings to justify the selection of a specific allocation method for your LCA.

Paragraph starter
The selection of an appropriate Life Cycle Assessment (LCA) allocation methodology is critical for accurately evaluating the environmental performance of circular design strategies. Research by Eberhardt et al. (2020) highlights that different allocation approaches, such as the Linear Degressive (LD) method, can significantly influence the distribution of environmental burdens and benefits across multiple life cycles of building components, thereby incentivizing distinct circular economy principles. This underscores the importance of carefully considering and justifying the chosen LCA allocation method within a design project to ensure that environmental assessments genuinely support circularity.
