Earth / Plant materials


The study focuses on construction methods and production methods that utilise natural materials available in each region in a recyclable way, with a view to realising a circular building system.



Research on the future of environmentally friendly earthen architecture.


Earth is abundant on the planet, can be applied to architecture in various states and forms, and is used in a variety of ways in all parts of the world. There is value in using earth as a building material from a variety of perspectives, such as reducing environmental impact, improving indoor environments, adding aesthetic and cultural value, and, in developing countries, providing housing and solving poverty issues. On the other hand, there are many challenges in using it in modern construction, such as the fact that it is hard work, takes a long time to construct and, because it is a natural material, there is a large variation in quality. In recent years, research and practice has been carried out in many areas with the intention of solving these problems, but in many cases the advantages of earth, such as its resource-recycling properties, have been lost.
The aim of this study is to discuss the future of environmentally friendly earthen architecture in the adoption of earth in contemporary architecture.



Construction Method for Mounting Earthen Blocks



Earth is a resource that exists everywhere on the earth, and there is little concern about its depletion. The resource recycling and moisture absorption/desorption properties of earth, which is only dried and solidified, are advantages that can be utilized in future construction. In Japan, the mud-bamboo wall construction method, which consists of layers of earth, has been mainly used, but it has many limitations in terms of construction period and cost. In other countries, a wide range of using earthen materials, such as rammed earth and sun-dried bricks, but many of them are assembled and are not suitable for Japan, which is an earthquake-prone region. On the other hand, the use of block-shaped earth units has the potential to free us from difficult techniques and constraints in terms of construction period and cost.

In this study, we develop a construction method that can be easily installed in building and ensures structural safety. The effect of the details of the proposed method on the structural safety will be investigated.
