Denmark has been a pioneer in promoting inclusive education, wherein the country intends to accommodate the specific needs of children in learning environments. The aim of this paper is to explore the roles played by design rules and guidelines in designing special needs schools in Copenhagen. I conducted interviews with project leaders, teachers and architects of those selected projects, through which key documents are identified. The findings provide new insights into the design process that supports producing good learning environments and school building plans for children with special needs in the context of promoting inclusive education.

Nishiya Purification Plant, built in 1915, supplies tap water to the urban critical area including Minato Mirai. Nishiya Purification Plant is currently undergoing renovation work to make the facility earthquake-proof and increase its treatment capacity. The six brick roof buildings remaining from the plant’s founding are nationally registered tangible cultural properties, but as they are difficult to preserve in their original locations, they will be earthquake-proofed and relocated. In order to plan the earthquake-proofing and relocation, it was necessary to understand the building materials, structure, construction methods and techniques, so the results of a building survey were reported here.

The series of communal work to replace thatched roofs using community resources is called “fushin”, and has been carried out by “yui”, a community of 25 to 30 households, with one house per year, taking turns. Kamanuma-Kita village in Kamogawa City, Chiba Prefecture, had been practicing “fushin” for ages, but the system was discontinued after the 1970s. Additionally, “Kayaba”, the thach fields in the village, were turned into cedar plantations. An understanding of the practice of thatching is essential for satoyama revitalization. This paper aims to illustrate the thatching process by decoding Fushincho and hearing local elders' experiences.

The authors have previously proposed a calculation method to reproduce the mechanical behavior of the joints in CLT rocking frames as a damage control technology for mid- to high-rise wooden buildings. However, there are issues such as the model used for the evaluation may differ from the actual behavior, and the embedded stiffness at the contact area between the column and beam was calculated based on predictions from other literature. Therefore, the goal of this research is to understand the mechanical behavior of the column-beam joints of CLT rocking structures and repropose an evaluation method.

The fluidity and compressive strength of mortar using five types of slag fine aggregate for concrete, including coal gasification slag aggregate, were investigated. As a result, the following conclusions were obtained. Even if the particle size distribution of the fine aggregate was made the same, the effect of the fine aggregate volume fraction on the J14 funnel flow test results differed due to differences in the particle shape of the fine aggregate. Furthermore, in this experiment, the change in the compressive strength of the mortar due to adjusting the particle size distribution of the fine aggregate was not large.

This paper describes the results of research on wall radiation cooling with using air mat as radiation-conscious cooling in residential building. The adequate conditions for supply air temperature and volume rate are derived such that thermal comfort is achieved. At those conditions, the electric power use for cooling is approximately 85% smaller than the metropolitan area average at least. If the system is working a whole day, even ventilation rate for infection-avoidance doesn’t give wall internal moisture condensation. On the other hand, shutting down the system at night increases the risk of condensation.

We are conducting research on the living environment of senior citizens with the aim of proposing a living environment where the senior citizens can live in health and safety. In Toki city, Gifu prefecture, where there is a large proportion of senior citizens, we measured the indoor environment of older house inhabited by senior citizen living alone and younger house inhabited by their children and grandchildren, both of which were built on the same site. We analyzed the indoor environment measurement results of two houses, compared the comfort from the measurement results, and analyzed the health risks for senior citizen.

By using a gripping device with a positioner, we have successfully achieved efficient processing with minimal material defects, even for small-diameter, irregularly shaped materials like thinned wood, resulting in high-quality building components. We developed and utilized a unique multi-axis processing machine with 9 degrees of freedom for this purpose. In a demonstration test, we produced a frame fence from high-design-quality heptagonal cross-section materials. Each joint of this fence uses traditional Japanese joinery techniques, showcasing the feasibility of intricate processing for polygonal cross-section timber.

This paper attempted to improve the usability of BIM by utilizing Excel, a familiar tool, and to create a system that would allow even owners with limited knowledge of BIM to perform effective factory maintenance management. Based on the literature, the authors summarized examples of BIM being used for FM and conducted interview surveys with the owner of the target building, a factory, to practically examine the utility and issues of using Excel for FM, and what an effective form of FM would look like for the target building.

There are few young skilled workers in the construction industry because of multi-layered subcontracting system and the problem of disguised independent contractor. These problems disadvantage skilled workers, so they should be resolved immediately. In this paper, we investigated them and revealed the actual conditions of the construction industry that we didn’t know before.
