Technology Can Transform Urban Architecture By Enabling Taller, More Durable, And Ecological Wooden Buildings
An innovation developed by scientists from Kyoto University may transform the way wooden structures are maintained in the future. The proposal promises to extend the lifespan of wooden constructions by detecting problems invisible to the naked eye.
The discovery represents an important advance for sustainable construction and could reignite the use of wood in modern buildings.
Old Problem, Invisible Solution
Wood has always been valued for its beauty and versatility, but it remains vulnerable to moisture and sunlight.

This becomes a significant obstacle, especially in outdoor structures. Traditional paints and varnishes help, but it is usually too late when the damage becomes visible.
To change this scenario, the research team created a method that allows monitoring the degradation of wood before it appears on the surface.
Professor Yoshikuni Teramoto, the study’s author, states: “If we can see what the eye cannot see, we can extend the lifespan of wooden structures and improve sustainability in the construction industry.”
Chemistry Allied With Artificial Intelligence
Teramoto’s group combined mid-infrared spectroscopy with machine learning. The technique detects minimal chemical changes in the wood coating, well before any physical signs. For this, a statistical model called PLS was used, which analyzes infrared spectrum data and predicts the condition of the material.
A type of genetic algorithm was also applied to identify which signals are most important for predicting deterioration.
The tests included conventional coatings and others with cellulose nanofibers (CNF), a plant material known for enhancing durability. The comparison between samples exposed to the weather with and without CNF showed that the method works with different types of formulations.
Intelligent And Sustainable Maintenance
The greatest benefit of the discovery is to enable automatic evaluation without damaging the material, reducing reliance on human visual inspections. This allows for action before the structure becomes compromised.
According to the researchers, the technology can also be applied to other materials such as concrete and metal, opening new possibilities for the maintenance of different types of infrastructure.
The next steps involve testing the technique in the field and developing commercial applications for paints and coatings. “We hope this technology bridges traditional craftsmanship and modern data science,” concludes Teramoto.
The study was published in the journal Advanced Sustainable Systems.
