Tatsuya INDEN, Associate Professor and Principal Investigator (PI) of this lab. Building on building materials science and construction engineering within the broader field of building production, I study sustainable building materials and digital manufacturing technologies. My specific research interests include the development of environmentally conscious building materials using underutilized resources such as pyroclastic materials and waste wood; the evaluation of hygrothermal and mechanical properties of materials; additive manufacturing (3D printing) of wood-based composites and earth-based materials; and the application of digital fabrication technologies - including 3D scanning and parametric design - to the field of architecture and construction. By integrating material experiments, manufacturing processes, and data analysis, I aim to develop innovative materials and production technologies that contribute to resource circulation and the advancement of building production
本研究室では，建築生産のなかでも建築材料学および建築施工学を基盤として，持続可能な建築材料とデジタル製造技術に関する研究を行っています。特に，火山砕屑物や廃木材などの未利用資源を活用した環境配慮型建材の開発，材料の調湿・力学特性等の性能評価，木質系複合材料や土系材料を対象とした積層造形（3Dプリンティング）、デジタルファブリケーション技術（3Dスキャナ・パラメトリック設計）の建築分野への応用に取り組んでいます。材料実験，製造プロセス，データ解析を横断し，資源循環と建築生産の高度化に資する新たな材料・製造技術の創出を目指しています。
研究分野における現在の問題点や関心事、見解など
In the architecture field, dealing with decarbonization and resource circulation has become an urgent task, while a complex mix of material properties, environmental conditions, and manufacturing and construction conditions is involved all the way from developing building materials to construction and maintenance. In particular, new materials made from underused resources are affected by regional differences and variation in raw materials, which makes it hard to generalize findings just by building up individual experimental results. I am interested in bringing together material experiments, construction technology, digital manufacturing, and computational and data analysis, building on conventional rules of thumb and experimental knowledge, to develop research methods that connect to sustainable building production.
建築分野では，脱炭素化や資源循環への対応が急務となる一方，建築材料の開発から施工・維持管理までには，多様な材料特性，環境条件，製造・施工条件が複雑に関係しています。特に，未利用資源を活用した新材料は，地域性や原材料のばらつきが性能に影響することから，個別の実験結果を蓄積するだけでは知見の一般化が難しいという課題があります。材料実験，施工技術，デジタル製造，計算・データ解析を横断的に統合し，従来の経験則と実験的知見を活かしながら，持続可能な建築生産へ接続する研究手法の構築に関心を持っています。
主な研究テーマ①
Development of Sustainable Building Materials Using Underutilized Resources 未利用資源を活用した持続可能な建築材料の開発
I work on developing sustainable building materials by making good use of underused or unused local resources, such as pyroclastic materials and waste wood, helping to lower environmental impact and support resource circulation. I study how raw material properties, mix proportions, and manufacturing conditions affect material performance, and I evaluate properties such as moisture control, heat and moisture behavior, mechanical strength, and durability. Through analysis of the data from these material experiments, I aim to build methods for predicting performance and designing materials that account for variation in raw materials, and I am working to put new materials and manufacturing technologies into practical use in place of conventional building materials.
火山砕屑物や廃木材など，地域に存在する未利用・低利用資源を建築材料として有効活用し，環境負荷の低減と資源循環に貢献する持続可能な建築材料の開発に取り組んでいます。原材料の性状や調合，製造条件が材料性能に及ぼす影響を明らかにするとともに，調湿，熱・水分特性，力学特性，耐久性などの性能評価を行っています。材料実験から得られるデータの解析を通じて，原材料のばらつきを考慮した性能予測や材料設計手法の構築を目指し，従来の建築材料に代わる新たな材料・製造技術の実用化を進めています。

地域連携・社会貢献活動
Connecting Research to Local Communities 地域社会と結ぶ建築生産の実践
I work with local communities, putting my knowledge and skills in building materials and construction to practical use for community service. For example, at the request of a welfare facility for the elderly in Setagaya City, my lab students and I build and assemble a "yagura" festival tower for the local summer festival every year. I also run a yearly training program in Ei Town, Minamikyushu City, Kagoshima Prefecture, focused on renovating and reusing vacant houses in the area. Through site surveys and hands-on renovation work, my students learn about building materials and construction methods in a practical way, while also thinking about the building and housing issues that local communities face. By connecting university education and research with local communities, I aim to give students practical learning experiences and help address local community challenges.
地域社会と連携し，建築・施工に関する知識と技術を実践的に活用した社会貢献活動に取り組んでいます。例えば，世田谷区内の老人福祉施設からの依頼を受け，研究室の学生とともに地域の祭りで使用される「やぐら」の製作・組立を毎年行っています。また，鹿児島県南九州市頴娃町では，地域の空き家を対象とした再生・活用に関する研修を毎年実施しています。現地調査や建物の改修作業などを通じて，学生が建築材料や施工技術を実践的に学ぶとともに，地域が抱える建築・住宅ストックの課題について考える機会としています。大学での教育・研究を地域社会と結び付け，学生の実践的な学習と地域課題の解決に貢献することを目指しています。
研究室・ゼミ活動
My laboratory, the Building Materials and Construction Lab, studies building materials science and construction engineering, with a focus on sustainable building materials and on combining digital fabrication with traditional craft work. Each student, whether working on a bachelor's or master's thesis, follows the full research process for their own topic: reviewing past studies, planning the research, making and testing materials, taking measurements with tools such as 3D scanners, organizing and analyzing the data, and discussing the results. In regular seminars, students report on their progress, introduce related papers, and discuss their research methods and findings with other lab members. I also encourage students to present at academic conferences, write papers, and take part in joint research with other universities and companies, so they can build strong practical research skills and scientific problem-solving abilities.
建築材料施工研究室では，建築材料学および建築施工学を基盤として，持続可能な建築材料や，デジタルファブリケーションと従来のクラフトワークの融合に関する研究活動を行っています。卒論生や修論生は各自の研究テーマに沿って，文献調査，研究計画の立案，材料の製作・実験，3Dスキャン等による計測，データ整理・解析，考察までの一連の研究プロセスに取り組みます。定期的なゼミでは，研究の進捗報告や文献紹介，研究成果の議論を行い，研究方法や分析結果について相互に検討します。また，学会発表や論文執筆，他大学・企業等との共同研究にも取り組み，実践的な研究能力と科学的な問題解決能力の育成を目指しています。

教員メッセージ
I am Tatsuya INDEN, an associate professor and the head of this laboratory. Building on building materials science and construction engineering, I study sustainable building materials and new ways of making buildings through digital fabrication. In my research, I place great value on hands-on work: making and testing materials, taking measurements with tools such as 3D scanners, analyzing data, and moving all the way through to digital design and manufacturing. I look at challenges the architecture field faces, such as using underused resources, resource circulation, and 3D printing, and combine building materials science, construction engineering, and digital technology to find new solutions. In the lab, students start from their own simple questions and move their research forward through experiments and discussion, also taking on academic conference presentations and paper writing. I want to look at the craft of "making" buildings from a scientific point of view, and think together with students about the future of building production.
