In an emerging longevity society, reimagining social infrastructure has become increasingly essential. The World Health Organization (2025) projects that the global population aged 60 and over will nearly double from 12% in 2015 to 22% by 2050, raising urgent questions about how people live and interact with services over time. This study introduces the service exposome, extending Wild’s (2005, 2012) exposome concept to consider the cumulative service-related exposures that shape well-being across the lifespan. Using the Design for Longevity (D4L) Unclock Framework—a tool that helps designers explore intersections across longevity, service, system, design, technology, and society—the research examines how early-stage design processes can uncover longevity-related needs. Drawing on two participatory workshops and survey data from 16 undergraduate design students at the Massachusetts College of Art and Design and Northeastern University, the findings suggest that the D4L Unclock Framework and service exposome concept can guide longevity-inclusive, systemic, and experiential design interventions.

This thesis reimagines the aging U.S. suburb as a site of transition, where single-family housing can evolve into distributed care infrastructure supporting longevity and community well-being. Through onsite research in Sacramento and collaboration with local care providers, the project develops a scalable framework for retrofitting suburban homes into neighborhood-based care hubs connected by shared food, mobility, and caregiver networks. Integrating architectural transformation, service design, and participatory co-design methods, it proposes a systemic approach that bridges individual housing adaptation with urban-scale resilience. Rather than pursuing technological “smartness,” the model advances a human-centered LongevityTech vision,where design mediates between housing, health, and social connection. By turning suburban fragmentation into an intergenerational ecosystem of care, this work illustrates how the built environment itself can transition alongside its aging residents, shaping more inclusive, adaptable, and age-ready futures.

The City of Longevity (CoL) framework integrates emerging technologies, participatory methodologies, and systemic service design to mainstream longevity in urban planning. Anchored in equity and intergenerational engagement, CoL introduces an AI-driven decision-support platform that translates longevity evidence into actionable urban policy through participatory co-design, KPI setting, and systemic service design principles. Following the Longevity as a Service (LaaS) concept, CoL advances a phased, coordinated implementation architecture whose deliverables are tailored to each municipality's cultural heritage and civic identity. This architecture is embedded within a collaborative inter-city network. Methodologically, this work synthesises convergent evidence from exposome science, longevity-ready urbanism, participatory design, and systemic service design into a layered architecture where each performs a distinct function, validated through pilot application in a real governance context. By establishing longevity as measurable and replicable rather than aspirational, CoL offers cities a scalable model supporting healthy, meaningful lives across generations.

This qualitative study examines social isolation among Boston's elders aged 65 and older. We explored ways to employ service design and interactive encounters to connect different generations around history. Our focus was on Boston’s Seaport—a district shaped by redevelopment and technology. This study involved four interviews with museum professionals, elders, and locals to understand how memories influence community connections. The Time Travelers app features an Interactive Memory Map of stories along with guided walks and collaborative memory threads that encourage intergenerational exchange. Complementing the app, a Seaport boardwalk installation features televisions from different decades displaying memories from each era. Visitors can browse stories and record their own through connected telephones. Together, these experiences transform public spaces and technology into portals of living history, promoting social engagement and purpose across generations. Future studies may examine Time Travelers’ long-term impact on social connections and expand participation to include more elders across Boston.

China's rapidly ageing urban population faces complex mental health challenges, particularly with comorbid conditions. Current elderly care is nonpersonalised and unresponsive to support holistic wellbeing. To address the challenges of inclusive, responsive, and adaptable senior care, this study suggests a human-centred digital twin framework that incorporates service ecosystem design.

This study employs a human-centred digital twin design methodology based on service ecosystem theory, focusing on how digital twins can mediate between users’ lived experiences and service innovation.

The findings from the literature review and design practice indicate that digital twin technology has potential foster older adults’ life experience, social inclusion, and psychological support beyond technical efficiency. This provides theoretical and practical guidance for designing age-friendly communities and emerging longevity technology cities based on smart service ecosystem.
