Saxton The Ecological Footprints of Tiny Home Downsizers: An Exploratory Study Maria W. Saxton ABSTRACT With our country’s unsustainable building practices in the residential sector, there is a need to explore new types of housing to mitigate the negative environmental impacts of current building customs. Recently, there has been a surge of interest in tiny homes characterized as livable dwelling units typically under 400 square feet. However, there is a gap in scholarly knowledge that formally examines how the environmental impact and behaviors of tiny home occupants change after downsizing from a larger home. The purpose of this study was to provide measurable evidence to explore the relationship between downsizing to a tiny home and the corresponding environmental impact. This study, which employed an exploratory sequential mixed design approach, was conducted to measure the ecological footprints of tiny home downsizers. Eighty individuals who have lived in their tiny homes for at least a year volunteered to take an online survey used to calculate their ecological footprints in prior larger homes and current tiny homes. Following the survey, nine interviews were conducted to create an inventory of noteworthy behaviors in each participant’s lifestyles that potentially influence ecological footprint changes. Data collected from the survey and interviews were analyzed separately and then comparatively to explore relationships between tiny home living and environmental impacts. This study found that among 80 tiny home downsizers located across the United States, the average ecological footprint was 3.9 global hectares (gha). This footprint was substantially less than the average previous ecological footprint of 7.0 gha and the national average of 8.4 gha. All five footprint components were positively influenced, showing that downsizing can influence many parts of one’s lifestyle. Over 100 behaviors were identified that could contribute to ecological footprint changes. The overall insights derived from this study indicate that positive environmental impact behaviors outweigh negative ones by approximately six to one when downsizing to a tiny home. In addition, 100% of participants demonstrated an overall positive ecological footprint. The findings and conclusions of this study provide important insights for the sustainable housing industry that can inform policy and practice, with implications for future research in the sustainable residential field.

Saxton GENERAL AUDIENCE ABSTRACT With our country’s unsustainable building practices in the residential sector, there is a need to explore new types of housing to mitigate the negative environmental impacts of current building customs. Recently, there has been a surge of interest in tiny homes characterized as livable dwelling units typically under 400 square feet. However, there is a gap in knowledge to understand how the environmental impact and behaviors of tiny home occupants change after downsizing from a larger home. The purpose of this study was to see whether there is a relationship between downsizing to a tiny home and a changing environmental impact. This study measured the ecological footprints of tiny home downsizers. Eighty individuals who have lived in their tiny homes for at least a year volunteered to take an online survey used to calculate their ecological footprints in prior larger homes and current tiny homes. Following the survey, nine interviews were conducted to identify noteworthy behaviors in each participant’s lifestyles that potentially influence ecological footprint changes. Findings were analyzed and compared to explore relationships between tiny home living and environmental impacts. This study found that among 80 tiny home downsizers located across the United States, the average ecological footprint was 3.9 global hectares (gha). This footprint was substantially less than the average previous ecological footprint of 7.0 gha and the national average of 8.4 gha. All five footprint components were positively influenced, showing that downsizing can influence many parts of one’s lifestyle. Over 100 behaviors were identified that could contribute to ecological footprint changes. This study indicates that positive environmental impact behaviors outweigh negative ones by approximately six to one when downsizing to a tiny home. In addition, 100% of participants demonstrated an overall positive ecological footprint. The findings and conclusions of this study provide important insights for the sustainable housing industry that can inform policy and practice, with implications for future research in the sustainable residential field. Dedication This dissertation is dedicated to Rachel Saxton, whose strength and resilience was a constant inspiration throughout this process. iv Acknowledgements My sincerest appreciation goes to Dr. Annie Pearce, my advisor, for her outstanding support throughout my undergraduate and graduate years at Virginia Tech. I will be forever grateful that you took a chance on a lone undergraduate. Thank you for your enduring support and mentorship for the past six years. Many thanks to my wonderful committee members; your collective guidance and varying perspectives made it possible to complete this dissertation. Dr. Freddy Paige, you have been my biggest supporter and advocate. Thank you for your encouragement and direction. Dr. John Wells, you pushed me to do my absolute best and helped me set a high standard for myself. Thank you for sharing your wisdom and experience to help me become a stronger researcher. Kevin Jones, you helped to keep me grounded and remember my roots in design. Thank you for your insights and for being willing to advise from afar in my last semester. I am also grateful to the Myers-Lawson School of Construction, the BioBuild interdisciplinary fellowship program at Virginia Tech, and the Global Forum on Urban and Regional Resilience initiative for the financial support and opportunities. I am also very appreciative of friends in the Sustainable Facilities and Infrastructure Lab at Virginia Tech who were always there to offer support and encouragement. One of the greatest fortunes in life is being part of a fantastic and devoted family. To my incredible parents, May and Mike Saxton, thank you for always believing in me and supporting me no matter what. You’ve always taught us that hard work and dedication will pay off.
