Protecting buildings and building materials from water is essential to the longevity of buildings. This is because many materials used in buildings deteriorate when they come in contact with water.

Globally speaking, Japan is a rainy country with high annual rainfall. As a result, the technology, materials, construction methods, and workmanship of rainproofing and waterproofing have long been developed, and are of a high standard among the world. On the other hand, the recent severe weather has made it necessary to withstand an even harsher environment, and the shortage of labor has also led to a demand for labor saving.

Therefore, we continue to conduct research to realize durable buildings.

Examples of research themes
・Research on wind resistance of membrane waterproofing layers
・Research on labor saving in membrane waterproofing
・Research on the repair of waterproofing membranes
・Research on waterproofing of waterproofing membranes
・Research on waterproofing defects of waterproofing membranes such as blistering
・Research on rainproofing mechanisms for flat roofing materials such as decorative slate roofing
・Research on the durability of sealing materials

Due to the recent severe weather conditions, wind storms and torrential rains have been causing flooding and other disasters throughout Japan every year. The building envelope, including roofs and walls, must be resistant to these disasters. In the event of a disaster, it is desirable to be able to recover as quickly and easily as possible, and if components are to be used continuously, they must be maintained in good condition afterwards.

Therefore, we are conducting research on building materials used in the building envelope and floors.

Examples of research themes
・Research on water absorption and drying characteristics and performance of various members of wooden detached houses in case of flooding damage
・Research to maintain sound nail pullout resistance of baseboards (sorting out various factors that cause a decrease in strength)

The ancient Greek physician Hippocrates said, “The farther a man is from nature, the closer he is to disease. In 1984, American sociobiologist E.O. Wilson proposed the biophilia hypothesis, which states that “people instinctively seek connection with nature. In architecture, the hypothesis has been adopted as biophilic design, and rooftop greening, wall greening, and indoor greening have been constructed.

In Chiba Prefecture, where our university is located, neglected bamboo forests are a problem. Bamboo charcoal is one example of a way to utilize bamboo that has been cut down. The pore structure of bamboo charcoal allows it to absorb and absorb odors and moisture vapor, and bamboo charcoal is spread under the floors of Kinkakuji and Ginkakuji temples to prevent wood decay. Bamboo charcoal can also be used in various other ways in construction.

Therefore, we are conducting research to realize sustainable architecture.

Examples of research themes
・Research on the rainwater storage effect of rooftop greenery (rainwater drainage delay effect)
・Research on utilization of bamboo charcoal
・Impression evaluation of architectural greening
