In the Environmental Infrastructure Laboratory, studies are underway to outline the ideal “Environmental Infrastructure” suitable for supporting building and urban environments from the perspectives of both “social capital” (i.e., urban infrastructure, urban installations, building equipment, etc.) and “natural capital” (i.e., natural elements such as water, green, wind, and soil). The aim of Building/Urban Environmental Engineering is to ensure people live and work in a safe, comfortable, efficient, and healthy environmental space. Through these activities, our laboratory dynamically discusses and actively promotes a hands-on approach to contributing to the local community, which has a high degree of social significance.
