As urban areas become increasingly dense and vertical, the nature of fire hazards becomes more complex. High-rise buildings, while maximizing space, also create unique challenges for fire safety management. With this growing concern, institutions and researchers worldwide are called to innovate and provide solutions tailored for modern architectural landscapes. The Hong Kong Polytechnic University (PolyU) is at the forefront of this mission, spearheading initiatives to bolster firefighting capabilities within urban settings. Their latest contributions, encapsulated in advanced technological frameworks and strategic research, hold promise for enhancing public safety and urban resilience.
In response to the pressing need for effective risk management in urban environments, the PolyU launched the “SureFire: Smart Urban Resilience and Firefighting” project. Spearheaded by Professor Asif Usmani and Dr. Huang Xinyan, this initiative engages researchers from multiple disciplines to explore fundamental fire safety questions. The second installment of the International Smart Firefighting Workshop (SureFire 2024) served as an important platform to foster discussions among over 70 international experts, who tackled the latest developments in fire safety design, thermal management for battery systems, and the incorporation of artificial intelligence in fire forecasting.
At the heart of the SureFire project is a sophisticated system that harnesses complex data networks for real-time environmental monitoring. This cutting-edge system adopts an AI-driven data analysis approach, allowing for continuous evaluation of urban fire risks. This proactive strategy not only identifies emergent issues but also significantly enhances decision-making processes during fire emergencies.
A cornerstone of the SureFire project is the introduction of an intelligent digital twin system. By integrating an Artificial Intelligence of Things (AIoT) framework with advanced computer vision technology, this system enables real-time assessments of fire risks within high-rise buildings. Prior to a fire, this digital twin can accurately model the distribution and risk profiles of various vehicles present in the structure, providing critical situational awareness.
In the event of a fire, the system goes beyond immediate assessments, offering predictive capabilities that project fire progression—an invaluable feature for guiding firefighting strategies and facilitating safe evacuations. The accuracy of predictions generated by the system exceeds 90%, having been validated through extensive large-scale fire tests conducted in diverse environments, including tunnels and multi-story buildings.
The implications of the SureFire system extend far beyond theoretical applications. The PolyU team is collaborating with various property management firms in China and internationally, aiming to implement this technology in metro stations, tunnels, and high-rise buildings. Particularly noteworthy is the development of a Smart Dynamic Exit sign system, designed to guide individuals through buildings during fire emergencies—a concept realized through the efforts of the PolyU start-up, GABES.
The applications of the SureFire system are multifaceted: while its primary function is to mitigate casualties during fire incidents, its potential to enhance the operability of firefighting robots represents a significant leap toward automation in emergency responses. As the PolyU team continues to advance these technologies, they are also working on the next generation of autonomous firefighting robots, potent tools designed to support human firefighters and further reduce risks associated with fire outbreaks.
The innovative advancements emerging from the PolyU not only serve as a beacon for improved fire safety but also contribute to the broader vision of creating smarter urban environments. By leveraging cutting-edge technology and robust data analytics, the university’s endeavors encapsulate a comprehensive approach to urban resilience—integrating fire risk management within the fabric of smart city initiatives.
As research progresses and more sophisticated systems are rolled out, Hong Kong is poised to establish itself as a global leader in the integration of intelligent technologies for public safety. The foundational work being completed today promises to redefine the approach to emergency management, fostering a safer and more resilient urban future.
The Hong Kong Polytechnic University’s advancements in fire safety through the SureFire initiative exemplify the interplay between technology and public safety. As challenges in urban development evolve, so too must our methods for tackling them, making the ongoing work at PolyU crucial in shaping the future of emergency response and urban resilience.
