Cyber-Physical-Social Infrastructure Systems (CPSIS) are an emerging research frontier focused on infrastructure that not only integrates physical and digital technologies, but also accounts for the people who use, shape, and are affected by them. From energy systems that adapt to occupant behavior to public spaces that foster social connection, CPSIS research seeks to design, operate, and evaluate infrastructure in ways that deliver measurable human, environmental, and system-level benefits. Achieving this requires methods to sense and model human behavior, incorporate social and community priorities into technical design, and address challenges of privacy, ethics, and access.

The CPSIS’25 workshop at ACM BuildSys 2025 convenes researchers, practitioners, and industry leaders working at the intersection of the built environment, computing, and human behavior. This year’s full-day program will feature invited keynotes spanning engineering, architecture, and the social sciences; peer-reviewed presentations; and collaborative breakout sessions focused on completing a community-driven position paper that began with preliminary steps in last year’s workshop. This paper will define technical priorities, interdisciplinary challenges, and pathways for impact in CPSIS research. Representative topics include human-centric sensing, behavioral and social modeling, deployment strategies, sociotechnical design principles, and the ethics of human-infrastructure interaction. CPSIS’25 offers a unique forum for shaping next-generation infrastructure systems that integrate technical innovation with a deep understanding of human dynamics and the built environment.

The workshop, which will be co-located with ACM BuildSys 2025, is soliciting submissions for peer review.

Topics of interest include, but are not limited to:

– Applications and deployments of CPSIS in domains such as education, healthcare, well-being, accessibility, co-design, public infrastructure, and urban systems

– Data-driven modeling techniques: agent-based models, cognitive and behavioral models, and models of social dynamics in built environments

– Integration of human and community constraints into the design and control of infrastructure systems

– Quantification and measurement of human-infrastructure interaction and the social value of the built environment

– Security, privacy, and ethics in CPSIS, including privacy-preserving techniques for human-centered sensing and monitoring

– Human-centric sensing and networking: incorporating mobile and wearable devices (e.g., smartphones, smartwatches) alongside fixed infrastructure (e.g., cameras, WiFi, RFID, lighting)

– Multi-device system design for applications such as health monitoring, localization, human behavior inference, and adaptive UI/UX
