Buildings designed with disassembly and flexibility in mind demonstrate substantial reductions in climate impact across various future use scenarios, irrespective of the specific allocation method used in Life Cycle Assessments. This sustainability research insight is drawn from a 2025 study published in Buildings. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Integrate design for disassembly and flexibility principles from the outset of a building project to achieve measurable reductions in lifecycle environmental impact.

Key Findings
- 01All circular scenarios (S1, S2, S3) resulted in lower climate impacts compared to the linear reference scenario (S0).
- 02Reductions in climate impact within the system boundary (A-C) ranged from 8% to 50%, influenced by the scenario and allocation method.
- 03Including future scenarios in LCA is more effective for promoting circularity than the choice of allocation method.
- 04The 50:50 allocation method showed the lowest impacts within the system boundary, while system expansion yielded the largest overall reductions but relied on uncertain assumptions.
Application
Design takeaway
Integrate design for disassembly and flexibility principles from the outset of a building project to achieve measurable reductions in lifecycle environmental impact.
How to apply

Project actions
- 01When evaluating design options, consider their potential for disassembly and future adaptation.
- 02Use LCA tools to compare the environmental impact of different design strategies, focusing on future scenarios.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive LCA covering multiple modules (A-D).
- +Comparison of multiple future scenarios and allocation methods.
- +Focus on a real-world building design.
Limitations
The complexity of full LCA can be challenging for smaller design projects. Estimating future scenarios and material reuse potential requires research and informed assumptions.
Reliability & validity
The study's validity is supported by its use of established LCA methodology and a real-world case study. Reliability is enhanced by testing multiple scenarios and allocation methods. However, the reliance on assumptions for future scenarios and system expansion introduces potential variability.
Think critically
Beyond environmental impact, what are the economic and social benefits of designing buildings for disassembly and flexibility that could further justify their adoption?
Design Principles
"Design for adaptability and deconstruction to maximize resource efficiency and minimize environmental footprint across a building's lifecycle."
This research highlights that proactive design choices for adaptability and deconstruction are more impactful for environmental performance than the nuances of LCA allocation methods. It provides a clear directive for designers and engineers to prioritize these features to achieve genuine sustainability in the built environment.
What This Means for Your Design
If you design a building so it can be easily taken apart and changed later, it's much better for the environment than just demolishing it. How you calculate the environmental savings isn't as important as planning for these future changes.
How to use in your project
- 1.Reference this study when discussing the environmental impact of design choices, particularly those related to building longevity, adaptability, and end-of-life considerations.
- 2.Use the findings to support the selection of design strategies that promote circularity in construction projects.

Paragraph starter
The research by Moberg and Görman (2025) highlights that designing buildings for disassembly and flexibility can lead to significant reductions in lifecycle climate impact, with potential savings up to 50%. Their findings underscore that the inclusion of future use scenarios in Life Cycle Assessments is more influential in promoting circularity than the specific allocation method used, providing a strong rationale for prioritizing adaptable and deconstructible design strategies in construction projects.
