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...

Reuse of discarded wood and alternative wood species to replace spruce in the development of wooden windows for complete disassembly – REWINNUSE
2023 - IRG/WP 23-30785
The REWINNUSE project focuses on the reuse of discarded wood and alternative wood species and on the development of wooden windows that can be easily disassembled into their basic components. In cooperation with the project partners (M Sora, the University of Ljubljana Biotechnical Faculty (BF), the Norwegian Institute of Bioeconomy - NIBIO and the Slovenian Forestry Institute (GIS)), the project ...

Japanese traditional wooden building construction project in Bangkok - Part 1 Project outline, building implementation and effects
2023 - IRG/WP 23-40992
The purpose of this project is to build new ways to utilize wooden resources in Japan. Japan's forestry industry is in decline despite its abundant forest resources due to a lack of successors and other reasons. Meanwhile, in Southeast Asian countries, reinforced concrete houses, which are not suited to the climate, are on the rise due to a lack of wood and technology. To solve these problems in b...

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 ...

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...

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...

The spread of technology in a simple wooden pile construction method to prevent shallow landslides
2025 - IRG/WP 25-20733
This study introduces the development and practical application of an innovative slope stabilization technique called the Wood Pile Root System Method (WPRSM), aimed at preventing shallow landslides, which have increased due to the rising occurrence of extreme weather events caused by climate change. This method effectively reinforces slopes using thinned timber, providing a sustainable and cost-e...

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...

Investigation of Pressure-Treated Foundations with Wood Preservative and Termite Control in Existing Wooden Houses in Japan
2025 - IRG/WP 25-50402
Japan has extremely limited natural resources. Therefore, it is necessary to build a circular economy in which waste and other recyclable resources are effectively utilized in order to achieve sustainable development. This study aims to investigate the degradation of existing wooden houses and to contribute to the reuse of existing houses and the reuse of building materials during demolition. We i...
