Designing for durability and incorporating sustainable materials and technologies throughout a building's service life significantly enhances its overall sustainability performance. This sustainability research insight is drawn from a 2021 study published in Environmental and Sustainability Indicators. Using Life cycle sustainability assessment (lcsa), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design for longevity and incorporate sustainable material and energy strategies from the outset to maximize a building's long-term sustainability benefits.
Extending building service life by 50% can improve sustainability by 30-49%

Key Findings
- 01Buildings incorporating recycled steel-framed roofs, brick walls, and green concrete demonstrated higher sustainability performance.
- 02The use stage (energy consumption and maintenance) emerged as a significant 'hotspot' for sustainability impacts.
- 03Implementing cleaner production strategies like double-glazed windows and rooftop solar photovoltaic panels improved sustainability performance by 30-49%.
- 04Material selection at the design phase is crucial due to its influence on durability and thermal properties.
Application
Design takeaway
Design for longevity and incorporate sustainable material and energy strategies from the outset to maximize a building's long-term sustainability benefits.
How to apply
When designing new buildings or renovating existing ones, conduct a lifecycle assessment to identify key impact areas and explore material substitutions and technological integrations that enhance durability and reduce operational energy consumption.
Project actions
- 01When selecting materials for your design project, research their lifecycle impacts, not just their initial cost or appearance.
- 02Consider how your design will be maintained and operated over time, and integrate features that reduce energy and resource consumption.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Application of a comprehensive LCSA framework.
- +Consideration of the entire service life of buildings.
- +Quantification of improvements through cleaner production strategies.
Limitations
It can be challenging to accurately predict the exact service life of a building or the long-term performance of all materials and technologies.
Reliability & validity
The reliability of the LCSA framework depends on the accuracy of the data inputs for material properties, energy consumption, and end-of-life scenarios. Validity is enhanced by the systematic application of the framework and the comparison of multiple building scenarios.
Think critically
To what extent can the 'service life' of a building be reliably predicted, and how might variations in this prediction impact the validity of LCSA findings?
Design Principles
"Holistic lifecycle assessment is essential for optimizing the sustainability of built environments."
This research highlights that a building's environmental and social impact is not static but evolves over its entire lifespan. Designers must consider not only initial material choices but also ongoing operational and maintenance phases to achieve true sustainability.
What This Means for Your Design
Buildings can be made much more sustainable by choosing materials that last longer and by adding things like solar panels and better windows, which cuts down on energy use and waste over the building's life.
