Life Cycle Assessment reveals that traditional solvent-based paints, like alkyd, have a significantly greater environmental and human health impact compared to water-based or gypsum plasterboard finishes. This resource management research insight is drawn from a 2023 study published in SVU-International Journal of Engineering Sciences and Applications. Using Life cycle assessment (lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: When specifying interior finishes, opt for water-based or low-VOC paints, or consider alternative materials like gypsum plasterboard, to significantly reduce the environmental and health impacts of a project.
Solvent-based paints incur 3x higher environmental burden than water-based alternatives in new urban developments.

Key Findings
- 01Alkyd (solvent-based) paint exhibited the highest environmental impact score (1.57 pt) and the greatest contribution to CO2 emissions (4.75 kg CO2 eq), primary energy consumption (65.61 MJ), and disability-adjusted life years (3.30E-06 DALY).
- 02Gypsum Plasterboard showed the lowest environmental impact across all measured metrics (0.45 kg CO2 eq, 5.19 MJ, 1.13E-06 DALY).
- 03Acrylic (water-based/low-VOC) paint demonstrated significantly lower impacts than solvent-based alternatives.
Application
Design takeaway
When specifying interior finishes, opt for water-based or low-VOC paints, or consider alternative materials like gypsum plasterboard, to significantly reduce the environmental and health impacts of a project.
How to apply
When selecting paints for architectural or interior design projects, request and review Life Cycle Assessment data to compare the environmental performance of different product options.
Project actions
- 01When choosing materials for your design project, think about where they come from and how they are made, not just how they look.
- 02Consider the 'end-of-life' of your chosen materials – can they be recycled or reused?
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilizes a robust Life Cycle Assessment methodology.
- +Provides quantitative data comparing multiple paint types.
- +Focuses on a real-world development project.
Limitations
The study did not account for the application process (e.g., VOCs released during painting) or the disposal of leftover paint, which could alter the comparative results.
Reliability & validity
The study's validity is supported by the use of LCA, a standardized methodology. Reliability would depend on the consistency of the data sources used for the LCA calculations and the specific impact assessment methods employed.
Think critically
How might the exclusion of the application and end-of-life phases in this LCA affect the overall ranking of paint types, particularly for materials that might have high VOC emissions during application or pose disposal challenges?
Design Principles
"Life Cycle Thinking: Evaluate the environmental impact of design choices across their entire lifecycle, from material sourcing to end-of-life."
This research highlights the critical need for material selection in construction projects to consider the full environmental lifecycle. Choosing lower-impact finishes can lead to substantial reductions in pollution and health risks, aligning with sustainable development goals.
What This Means for Your Design
Some paints are much worse for the planet and people than others. The study found that old-fashioned solvent paints cause a lot more pollution and health problems than newer water-based paints or even just using plasterboard.
How to use in your project
- 1.Use this study to justify the selection of specific, environmentally friendly materials in your design project, referencing the LCA findings to support your decision.

This research provides a critical benchmark for material selection in construction. The comparative Life Cycle Assessment of wall painting types revealed that solvent-based paints, such as alkyd, possess a significantly higher environmental and human health burden compared to water-based alternatives like acrylic paint and gypsum plasterboard finishes. Specifically, alkyd paints were found to contribute substantially more to CO2 emissions, primary energy consumption, and health impacts (DALY) than their less impactful counterparts. This underscores the importance of specifying low-VOC and water-based finishes in design projects to promote sustainability and occupant well-being.
