Abstract
In recent decades, academic and professional research has increased understanding of the importance of city and landscape planners engaging with social and environmental justice issues, including contemporary inequities inherent in the planning, distribution, use, and access of public green and open spaces. However, there is a gap between this research centering equity and the planning, development, and implementation rate demonstrated by public agencies. In this article, we examine examples of emerging practice in the public park and recreation sector to understand the strategies and approaches public agencies are taking to provide equitable park and recreation systems. Our research identifies and analyzes 17 examples of North American public park and open space management agencies using equity-based planning frameworks to prioritize park investment and resource distribution. Equity-focused resource analysis is distinct because while it assesses budget and project-based funding distributions, it further incorporates assessments of historical allocations to understand better areas of under-investment and the evolving needs of different communities. As economic inequities become more pronounced, local governments, and other public institutions providing services to populations, are important in helping communities navigate changes. Our findings support the ongoing advancement of equity-driven planning and implementation for public park and recreation agencies by providing practical information on existing approaches to redress the impact of unfair patterns of under-investment.
Life Cycle Lab
The Life Cycle Lab at UW’s College of Built Environments leads research to advance life cycle assessment (LCA) data, methods and approaches to enable optimization of materials, buildings and infrastructure. Our work is structured to inform impactful policies and practices that support global decarbonization efforts. We envision a transformed, decarbonized building industry – better buildings for a better planet.
Our group is led by Professor Kate Simonen. Since arriving at UW in 2009, she has conducted research and spearheaded initiatives focused on accelerating the transformation of the building sector to radically reduce the greenhouse gas emissions attributed to materials (also known as embodied carbon) used in buildings and infrastructure. From June 2010 until April 2024 she directed the Carbon Leadership Forum (CLF) as it was hosted in UW’s College of Built Environments. The core of CLF’s work has been to lay essential foundations for understanding embodied carbon: a framework for comprehensive strategy, rigorous analysis, and transparent reporting that can support design tools, effective policy, and collective action.
In April 2024, two new entities were created to expand the program’s influence and impact: the Carbon Leadership Forum launched as an independent nonprofit organization and the newly named Life Cycle Lab was created to support the next generation of researchers and pursue critical embodied carbon research with an increased focus on academic publications. Learn more about this transition via this announcement.
Life Cycle Lab members include professional research staff, research assistants, students advised by Prof. Simonen, undergraduate interns and student assistants. Many of our members are formally affiliated with the Carbon Leadership Forum and the two organizations continue to actively collaborate developing strategies and executing aligned initiatives.
Projects associated with Life Cycle Lab include:

Examining commute mode choice of essential workers before and during the COVID-19 pandemic – A case study of the University of Washington
Cai, M., Shen, Q., Wang, Y., Brown, M., Ban, X., & Ashour, L. A. (2024). Examining commute mode choice of essential workers before and during the COVID-19 pandemic – A case study of the University of Washington. Case Studies on Transport Policy, 15, 101129-. https://doi.org/10.1016/j.cstp.2023.101129
Abstract
During disruptive events and major crises such as the COVID-19 pandemic, essential workers, defined in this study as employees who must continue to make frequent commute trips, play a critical role in maintaining the basic function of society. It is therefore vital for transportation planners and policymakers to ensure that adequate mobility services are provided to meet the travel needs of this group of workers. To better understand essential workers' mobility barriers and inform future transportation policy, this research examines their pre-and during-pandemic commutes, as well as prospects on future commuting, using data from the Transportation Needs Assessment Survey conducted by the University of Washington in Seattle. The results show that, first, over 60% of pre-pandemic public transit riders switched to other modes, especially driving alone. In contrast, almost all the essential workers who drove alone, biked, or walked before the pandemic continued to do so during the pandemic. Second, the shift to driving alone was most pronounced among essential workers with high incomes, whereas public transit remained as a primary mode choice of lower-income groups. As travel distance increased, the probability of driving alone over public transit also went up, although the relationship was not linear. We did not find consistently significant associations between mode choice and other sociodemographic variables. Finally, our analysis indicated that most essential workers anticipated to return to their pre-pandemic commute frequency and mode choice when the pandemic is under control. Transportation planners and policymakers can facilitate mobility for essential workers through planning and policy innovations, especially during disruptive events and major crises.

3. Questioning “Best” Practices in Architectural Education
Cheng, R. (2023). 3. Questioning “Best” Practices in Architectural Education. In Kim, J. (Ed.), Interdisciplinary Design Thinking in Architecture Education. Routledge. ISBN 9781032283241.
Abstract
This book explores the creative potential for architecture curricula to integrate solid interdisciplinary thinking in design studio education.
Annotated case studies, both from academic institutions and from professional practices, provide examples of interdisciplinary engagement in creative design work, highlighting the challenges and opportunities of this approach. Cases are from a diverse selection of international collaborators, featuring projects from the United States, Australia, Mexico, Germany, and Italy, and cover a range of project types and scales. Chapters by invited experts offer speculations on current and future models, situating examples within the broader context, and encouraging dialogue between practice and pedagogy. The collection of voices in this book offers critical and provocative lenses, learning from history while forging inventive and creative roles for the architect as practitioner, entrepreneur, strategist, choreographer, activist, facilitator, leader, and teacher.
Interdisciplinary Design Thinking provides insights into the potential of interdisciplinary engagement at the level of foundational undergraduate education, making it ideal for faculty in architecture schools. It will also be of interest to design professionals concerned with interdisciplinary collaboration and how to incorporate similar efforts in their own practices.

Causal effects of place, people, and process on rooftop solar adoption through Bayesian inference
Min, Y., & Ko, I. (2023). Causal effects of place, people, and process on rooftop solar adoption through Bayesian inference. Energy (Oxford), 285, 129510-. https://doi.org/10.1016/j.energy.2023.129510.
Abstract
While previous studies have established correlations between rooftop solar adoption and various factors, a comprehensive understanding of the underlying causal mechanisms has been limited by the intricate interrelationships among these variables. To address this gap, we propose a Bayesian causal inference approach that examines the interplay of various factors influencing rooftop solar adoption across multiple cities. By employing post-phenomenology, we uncover latent variables encompassing place, people, and process, shedding light on how they shape public responses to emerging energy technologies. We analyze the causal effects of these factors and highlight the significance of housing and built environment attributes in determining energy expenditure and rooftop solar adoption, emphasizing the need for policies that target energy equity. Additionally, we reveal the influence of neighborhood spillovers on adoption, indicating the role of social norms and information diffusion. The observed city-level variability underscores the importance of local contexts and location-specific factors in the adoption process. Furthermore, we highlight the need to consider causal relationships and the indirect effects of people-related attributes mediated through place-related attributes. Overall, these findings contribute to a deeper understanding of the factors shaping rooftop solar adoption via causal modeling and underscore the importance of tailored policies to promote adoption.
