Evaluation of different wood by-products for sustainable building biomaterial production using fungal mycelium
2022 - IRG/WP 22-50373
As human population increases, the demand for new innovative, sustainable, and low impact construction materials also grows. Mycelium-based composites have shown to be an excellent alternative for traditional products ranging from low-density objects to semi-structural applications. They also present the advantage of using the waste streams from other productive processes as feedstock, enabling th...

Assessment of the Material Durability and Structural Integrity of the Wooden Velodrome in Češča vas, Slovenia
2023 - IRG/WP 23-11012
Wood is a widely used material in the construction industry, and it has been utilized for thousands of years to create buildings and other structures. When wooden structures are designed, built, and maintained properly, they can be safe and long-lasting. Sports facilities, which provide athletes with a space to train, compete, and improve their abilities, are crucial in creating a strong and susta...

Natural durability of 9 tropical species suitable for round wood timber building: fungi and termites laboratory screening tests
2023 - IRG/WP 23-11013
In numerous tropical forest species, wood properties are poorly described and wood is under-valorized. Especially very few is known about small diameter trees although they may be used, directly as round wood, in construction timber building. A selection of abundant species was done and characterization tests were performed to assess their usability as building material. The aim of this work was t...

Moisture performance of wooden shingles tested on the Golobar cable yarding
2023 - IRG/WP 23-20704
Wood is a traditional roofing material in Europe and other parts of the world. In the 17th century, wooden roofing was generally used on more important buildings, but today it is mainly used on huts and houses in the Alpine regions. As wooden roofing is expensive, we investigated the possibility of extending the service life of the roofing through material selection and details. The roof of the Go...

What products are architects using? Relationships between deterioration part and structural performance in wooden houses
2023 - IRG/WP 23-50374
Architects work in the development of ideas around buildings and all the nuclei where human activity is generated. It is a work of organization of matter, in time and space, where the conceptual world of ideas and the aspirations of inventions, the interior world interact with the exterior in many kinds of realities.
But as architects, we have always been interested in why and how things have bee...

Relationships between deterioration part and structural performance in wooden houses
2023 - IRG/WP 23-50376
Based on the survey examples, there are four patterns of deterioration that tend to occur in plywood bearing walls of wooden houses in Japan. The first is a pattern in which wall is in a whole deterioration. It is a no damage wall or test specimen. The second is a pattern in which only the sill is deteriorating. It is caused by moisture or termites from ground to the base. In addition, there is a ...

Enhanced durability of bio-based materials for green building
2023 - IRG/WP 23-50382
Wood protection technologies provide tools to enhance the durability of bio-based materials for green building. Both wood and related bio-based material are regarded as eminent for green building. It allows to underpin several of the United Nations sustainable development goals and is regarded critical for the Green Deal objectives of the EU. Nevertheless, to enhance the potential it needs to be b...

Eradication of beetles attacking wooden historical buildings by humidity-controlled warm-air treatment
2023 - IRG/WP 23-11028
Humidity-controlled warm-air treatment is a method that kills mainly beetles that are damaging the wood. In this process, a heat-insulating and airtight covering is placed around the object building, and the temperature inside the covering is gradually raised to about 60°C, held for a certain period of time, and then gradually lowered. While maintained at 60°C, all forms of damaging insects - ad...

Assessment of the condition of wooden mill in the area of Kovačevići in Bosnia and Herzegovina
2023 - IRG/WP 23-11030
An excellent example of cultural and technical heritage is almost 100 year old wooden mills near Cazin in Bosnia and Herzegovina. These mills played an important role, especially in times of Bosnian war (1992-95), when this region was cut off from electricity. The laboratory analysis revealed that the respective mill was made of chestnut (Castanea sativa) and oak (Quercus sp.) wood. The sufficient...

Investigating moisture dynamics and fungal decay risk: integrating X-ray CT visualization and simulation benchmarks through a Fungal Control Unit
2024 - IRG/WP 24-11045
Wood is susceptible to fungal attack and over time the structural integrity can be compromised. This risk is of course strongly related to moisture dynamics, as moisture is needed for fungal growth. While existing methodologies, such as lab and field tests, provide valuable insights into wood decay, they often fall short in replicating real-life conditions, particularly within the intricacies of t...

How personality traits influence the perception of fungal decay in a wooden cladding – A survey in three Modelling wood moisture content in outdoor conditions from measured data
2024 - IRG/WP 24-41002
This study examined perceptions of fungal decay damage on wooden cladding across Norway, Sweden, and Germany. The majority of respondents across all countries did not find the fungal decay damage in question acceptable, with the least acceptance in Norway. This could be due to Norway having the highest frequency of wooden residential buildings and the most experience with maintaining wooden claddi...

Decay pattern in external wooden structures
2025 - IRG/WP 25-11055
Decay in external wooden structures has historically been a universal problem of great concern. Despite this, the general understanding of where and why wood-decaying fungi are occurring is limited. The consequences of this are that decayed wood might not be detected and that measures to protect the wood against deterioration has limited effect.
Wood decay in different geographical and climatic ...

The non-energy utilization of low-quality wood from the invasive species Prunus serotina
2025 - IRG/WP 25-30814
Alien invasive species in Europe, such as Prunus serotina, can significantly impact ecosystem structure and function. This species provides low-quality timber, which is most often used for energy purposes in the form of biomass. In the era of policies focused on a circular economy, seeking methods to extend the life cycle of raw materials and wood products is necessary. For this purpose, the wood ...

Preservation conditions of wooden roofs of two historical churches in middle-Sweden
2025 - IRG/WP 25-41016
Assessment of biodegradation by the rot of shingles from the roofs of churches of Hammarby and Tångeråsa in mid-Sweden was done by studies with X-ray computer tomography. The study suggests that inner rot could be detected with CT, which was not always easily detected by visual inspection. In some cases, erosion from the weathered side was fairly large, but the inner wood part was found not to b...
