Fuente: WIPO "sustainability" This invention provides an urban planning and building design system based on seismic resilience, environmental sustainability, and urban expansion problems. Using real-time seismic risk assessment, adaptive structural design, and environmentally friendly materials, the system maximizes land use, infrastructure footprints, and building performance in urban areas. Technical specializations which include base isolators, lightweight hybrid structures, and prefabricated modular units provide structural flexibility and a high level of disaster resistance at a lower construction time and cost. It has also integrated IoT-ready sensors and digital twin technology to enable real-time monitoring and predictive maintenance thus increasing effectiveness in disaster preparedness and recovery. It uses low-carbon building materials, passive energy designs, and renewing natural resources such as green corridors and permeable pavements to prioritize environmental sustainability while reducing urban emissions and enhancing urban ecosystems. It is applicable in different urban settings and can apply to inner cities to the most concentrated and vulnerable areas concerning the impact of disasters. This invention supports sustainability all over the world in improving the safety and resilience of urban centers and contributes to the sustainability of an urban environment.
