Implementing a cradle-to-cradle life cycle assessment (LCA) methodology is essential for achieving truly circular building strategies in South Asian countries, but current practice and research are predominantly cradle-to-grave. This sustainability research insight is drawn from a 2023 study published in Buildings. Using Literature review with 71 papers, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Adopt a cradle-to-cradle approach in your design process, actively seeking or contributing to the development of regional data and advocating for context-appropriate sustainable building standards.

Key Findings
- 01Half of LCA studies used cradle-to-grave methodology, while the other half used cradle-to-cradle.
- 02There is a lack of cradle-to-cradle LCA implementation for circular building strategies in the studied region.
- 03Stakeholder awareness and interest in environmentally friendly buildings are low.
- 04Barriers to LCA include the unavailability of regional databases and context-specific certification criteria.
Application
Design takeaway
Adopt a cradle-to-cradle approach in your design process, actively seeking or contributing to the development of regional data and advocating for context-appropriate sustainable building standards.
How to apply
When designing buildings in regions with similar developmental stages or resource constraints, proactively investigate and address the availability of local data and the suitability of existing environmental assessment tools and certifications.
Project actions
- 01When researching sustainable design, specifically look for studies that use 'cradle-to-cradle' life cycle assessments.
- 02Consider the availability of local data and how it might impact your design choices for a specific region.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive review of a significant number of relevant papers.
- +Focus on a specific and important geographical region for sustainable development.
Limitations
The availability of specific regional data for LCA can be a significant challenge, potentially requiring estimations or the use of generic data, which may reduce accuracy.
Reliability & validity
The reliability of the review depends on the systematic search strategy and the quality of the included papers. Validity is enhanced by the focus on a specific region and topic, but the findings are limited to the scope of the reviewed literature.
Think critically
Given the identified barriers of data unavailability and lack of stakeholder awareness, how can designers and researchers in South Asia proactively drive the adoption of cradle-to-cradle LCA and circular building principles?
Design Principles
"Embrace a regenerative design philosophy by considering the entire lifecycle of materials and products, aiming for closed-loop systems rather than linear ones."
This highlights a significant gap in how environmental impact is assessed in the construction sector of South Asia. Designers and engineers need to move beyond linear 'end-of-life' thinking to embrace regenerative design principles that consider the entire material lifecycle for a sustainable built environment.
What This Means for Your Design
To make buildings truly 'circular' and good for the environment, we need to think about what happens to materials from start to finish and back again (cradle-to-cradle). In South Asia, most studies only look at the 'end of life' (cradle-to-grave), and there are problems with data and standards, plus people aren't very aware of these ideas.
How to use in your project
- 1.Reference this study when discussing the importance of cradle-to-cradle LCA for circular economy principles in your design project.
- 2.Use the identified barriers (data, standards, awareness) to justify the need for your proposed design solution or research.

Paragraph starter
This research highlights a critical gap in the application of Life Cycle Assessment (LCA) for circular building design in South Asia, where a predominant 'cradle-to-grave' approach is observed, rather than the essential 'cradle-to-cradle' methodology required for true circularity. The study identifies key barriers, including the lack of regional databases and context-specific certification criteria, alongside low stakeholder awareness, underscoring the need for localized data and tailored approaches in sustainable construction projects.
