Name KAYO Genku
Official Title Associate Professor
Affiliation Faculty of Environmental Studies, Department of Restoration Ecology and Built Environment
Profile Genku Kayo is a researcher who actively crossover the disciplines of architectural design, building engineering, and energy engineering. He explores the future energy use in districts by mathematical modelings. In the study on decentralized energy systems, renewable energy applications expanding the scale from a single building to a cluster of buildings were carried out using genetic algorithms. The concept was applied in campus buildings in the context of sustainable campus development. Now he is involved in IEA EBC Annex64 (Low Exergy Communities), or IEA EBC Annex83 (Positive Energy Districts). By collaborating with a scientific professional, he takes responsibility as a subtask leader and develops tools and methods for simulating district-scale energy systems. In addition, he is active applying numerical analysis for architectural design study and supports creative practices. He collaborates with architects and supports their architectural climate responsive design based on a knowledge of building physics, thermodynamics, and mathematical modeling. The methods and approaches are not limited only to design work but also the actions of residents to build an understanding of energy and climate in daily life. Since he has career records employed in universities in Finland and Sweden (2012-2019), he is involved in international communities especially in Nordic regions.
Research Field(Keyword & Summary)
  1. Thermodynamics, Mathematical Modeling, Building Simulation, Environmental Design, Energy Community

    Our challenge is to explore ways to get a better understanding of energy flow in our built environment, and to become a responsible person to manage our energy flow by ourselves as a member of "energy community". To achieve the aims, we apply research methods such as environmental scanning, building performance simulation, and mathematical modeling, and try to generate and propose new ideas towards a sustainable future. The research is carried out with the knowledge from building physics, thermodynamics, or architectural engineering, but also done together with researchers from such as computer science, architecture, energy engineering, product design, and so on as interdisciplinary collaboration.
