A comprehensive Life Cycle Assessment (LCA) of 22 building materials highlights substantial differences in their environmental impact, particularly concerning energy consumption and carbon footprint, guiding more sustainable material selection. This sustainability research insight is drawn from a 2023 study published in Journal of Architectural Environment & Structural Engineering Research. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers should actively select materials with lower embodied energy and carbon footprints, such as wood, masonry, and certain types of concrete, over high-impact materials like steel and aluminum where feasible, to reduce the overall environmental burden of a project.

Key Findings
- 01Materials like aluminum, ceramics, PVC pipe, and expanded polystyrene (EPS) foam are high energy consumers.
- 02Steel, stone, plaster, rebar, bitumen, concrete, glass, cement, gravel, and EPS foam are identified as high-carbon materials.
- 03Masonry blocks, wood, tiles, bricks, drywall, MDF, and cement mortar are identified as low-carbon materials.
- 04Thermal conductivity varies, with most materials around 0-2 W/m.K, but exceptions like lime, aluminum, rebar, and steel show higher values.
Application
Design takeaway
Designers should actively select materials with lower embodied energy and carbon footprints, such as wood, masonry, and certain types of concrete, over high-impact materials like steel and aluminum where feasible, to reduce the overall environmental burden of a project.
How to apply
When selecting materials for a design project, use LCA data to compare the environmental footprint of alternatives and choose options that align with sustainability goals.
Project actions
- 01When choosing materials for your design, research their environmental impact using LCA data.
- 02Consider the 'cradle-to-grave' impact of your material choices.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Comprehensive analysis of a wide range of common building materials.
- +Utilizes established LCA methodologies and databases.
Limitations
The availability and accuracy of LCA data can vary, and regional differences in production and supply chains can significantly alter a material's true impact.
Reliability & validity
The reliability of the findings depends on the accuracy and comprehensiveness of the Ecoinvent v3 database and the specific assumptions made within the Simapro8 software. Validity is enhanced by focusing on widely used materials and established LCA metrics.
Think critically
How might the 'embodied impact' of a material influence its long-term performance and maintenance requirements, and how can these factors be balanced in a design decision?
Design Principles
"Embodied Impact Prioritization: In design, prioritize materials with demonstrably lower lifecycle environmental impacts (energy, carbon, water) to achieve greater sustainability."
Understanding the full environmental cost of materials, from extraction to disposal, is crucial for designing and constructing buildings that minimize ecological harm. This insight empowers designers to make informed choices that contribute to reduced carbon emissions and resource depletion.
What This Means for Your Design
This study looked at how much energy and pollution different building materials create from start to finish. It found that some materials are much worse for the environment than others, helping us choose better ones for buildings.

Paragraph starter
The selection of building materials significantly influences a project's environmental footprint. Research, such as that by Ghanbari (2023), employing Life Cycle Assessment (LCA), demonstrates that materials like steel and aluminum have substantially higher embodied energy and carbon emissions compared to alternatives like wood and masonry blocks. This highlights the critical need for designers to prioritize materials with lower lifecycle impacts to achieve greater sustainability in their designs.
