Background: With the increasing global population of older adults, there is a need for environmental interventions that directly affect their physical, psychological, and emotional well-being to help them maintain or regain their independence and autonomy – all of which promote longevity. Methods: To better understand potential opportunities and challenges associated with interior design and “future homes” that may promote well-being, aging in place, and independent living in older adults, the authors reviewed relevant literature and included their own expert opinions from a multidisciplinary point of view including interior design, wellness, and engineering. Results: After summarizing existing environmental interventions for the aging population and their effectiveness, this review reveals knowledge gaps in interior design for the well-being and longevity of older adults followed by a discussion of opportunities for future research that may fill these gaps. Some of these opportunities include finding habilitative design strategies that identify and address unique situational needs of each user, advancing multidisciplinary fields such as environmental gerontology that recreate security and independence for older adults even outside of their homes, implementing technically advanced design strategies, which are flexible and adaptive to individual needs; and integrating the Internet of things (IoT) into living environments, including voice-activated command technologies to improve seniors’ central role in enabling an optimized healthcare ecosystem. Conclusions: Knowledge of current evidence regarding the impact of different environmental factors may hasten adaptation of well-designed innovations that can provide optimal healing and living environments for the aging population. By effectively addressing older adults’ unique and specialized needs, design practitioners can become an indispensable part of their medical, social, and environmental team. One of the rapidly developing infrastructures promising to revolutionize the design of “future homes” is the IoT. While it is at an early stage of development, ultimately we envisage a connected home using voice-controlled technology and Bluetooth-radio-connected add-ons, to augment much of what home health does today. Bringing these approaches together into an effective strategy for a model of effective geriatric care is important and needs to become an integral part of both design education and practice.

This Special Issue on Healing Spaces includes eight articles consisting of studies at the interface between design and health. The articles address some of the latest findings using state-of-the-art technologies, important outcomes for human health and wellbeing, and suggest exciting directions for the future of this research field.

This book reveals how subjective and objective data gathered by innovative methods of measurement give us the ability to quantify stress, health, performance, and wellbeing outcomes in different built environments. Design interventions informed by these measures, along with innovative integrated building materials, can shape the character of built environments for better health, productivity, and performance. These measures can help employers and managers calculate the return on investment (ROI) of various design interventions. Areas of inquiry in health and the built environment are discussed in three parts: Part 1 – Fundamentals: Human, Environment, and Material Measures for Health and Wellbeing; Part 2 – Methods: Measurement Techniques, Tools, and Methods for Health and Wellbeing; and Part 3 – Applications: Case Studies and Future Directions. The rapid pace of technical innovation and entrepreneurship by interdisciplinary research teams in health and the built environment has created a need for more publications such as this book, which discuss latest tools and methods of measuring the effects of the built environment on human physiology and psychology. Emerging tools and techniques are introduced for this field of built environment design, including virtual reality immersive environments and fisheye lens photograph simulations for human wellbeing impact measures integral to the design process. The potentials and limitations of bio‑responsive material systems and integrated sensing devices with wearable technologies linked to the Internet of Things are discussed in relation to human wellbeing performance improvements. The book provides both the foundational knowledge and fundamentals for characterizing human health and wellbeing in the built environment as well as emerging trends and design research methods for innovations in this field. It will be of interest to researchers, educators, and students of architecture, interior design, and integrative medicine, as well as professionals working in health and the built environment. <!----> <!----> <!----> <!---->
