Imamoto Lab

A lab that studies the preservation of pioneering-era buildings and the architecture of the future from the perspective of building materials.
AboutAbout the lab
Rethinking the preservation and future of buildings through building materials.
The Imamoto Lab studies the preservation of pioneering-era buildings and the architecture of the future from the perspective of building materials.
The lab also works on preserving World Heritage-related buildings, such as the structures on Gunkanjima (Hashima Island) and the structural frame of the main building of the National Museum of Western Art.
Developing new materials is also a research theme, including building materials that use phase change materials and cement-free concrete.
Through the prediction of deterioration in exterior finishing materials and non-destructive techniques for estimating deterioration in reinforced concrete, the lab studies maintenance methods that make buildings last longer.
Key terms
- Phase change materials
- Materials that make use of the heat absorbed or released when they change state. In this lab, they are used to regulate the temperature of building materials.
- Cement-free concrete
- Concrete made without cement. The lab studies it as a material that reduces environmental impact.
- Non-destructive
- A method of examining the internal condition and the degree of deterioration of a building or material without damaging it.

ResearchResearch themes
The Imamoto Lab studies the preservation of pioneering-era buildings and the architecture of the future from the perspective of building materials. Its research is divided into three areas: durability assessment and preservation of modern and contemporary buildings, new material development and material design for environmental harmony, and extending the service life and maintenance of buildings.
*Illustrative imageDurability Assessment and Preservation of Modern and Contemporary Buildings
The lab works on predicting the service life of the structures on Gunkanjima (a component of a World Heritage Site) and developing repair and strengthening techniques for their preservation. It also evaluates the durability of early reinforced concrete masterpieces of architecture and develops preservation methods from a materials perspective, and carries out preservation and renovation of the structural frame of the main building of the National Museum of Western Art.
*Illustrative imageNew Material Development and Material Design for Environmental Harmony
The lab develops temperature-regulating building materials that use phase change materials, and hybrid prestressed concrete, which introduces prestress into high-strength fiber-reinforced concrete. It also works on a structural system combining locally sourced rammed-earth blocks with steel frames (joint research with the Ito (Takumi) Lab), and on structural materials with a lower environmental impact, such as cement-free concrete.
*Illustrative imageExtending the Service Life and Maintenance of Buildings
The lab predicts the deterioration of exterior finishing materials probabilistically and develops maintenance methods. It also works on repairing and strengthening timber buildings damaged by termites, and on developing non-destructive techniques for estimating the progress of deterioration in reinforced concrete buildings.
