Mel Chafart is a Researcher with the Carbon Leadership Forum where he is primarily focused on researching Whole Building Life Cycle Assessments. Prior to joining the CLF, Mel was a structural engineer at Buro Happold. There, he assisted in the design of steel and concrete structures in the US and abroad. He has worked on projects from concept design through construction administration. On the embodied carbon side, Mel has deep experience performing embodied carbon assessments and helped Buro Happold build out their portfolio of benchmarked projects. Outside of work, he enjoys watching soccer and baseball, woodworking, gardening, and tinkering with Raspberry Pis.

Built environment scholarship at the scales of the interior space to the building
Milad Ashtiani
Milad Ashtiani is a Building and Materials Researcher with Carbon Leadership Forum. Milad is a civil engineer who received his PhD from the University of Washington in the summer of 2022. Milad is responsible for the execution of research and analysis, development of guidance documents and educational resources, and outreach across the design community to improve the quality, accuracy, and effectiveness of building performance tools, methods and data that address embodied carbon. As a building and materials researcher, Ashtiani works collaboratively with CLF’s internal research team as well as with architecture and engineering firms and research consortiums across North America with a focus on building performance, computation, embodied carbon assessments, and life cycle assessment (LCA).

Urban Infrastructure Lab Report on High-Speed Rail
The Urban Infrastructure Lab researchers have released a report on a Cascadia region high-speed rail project. College of Built Environments faculty Jan Whittington and Qing Shen were authors on the report, along with 3 Interdisciplinary Ph.D. in Urban Design and Planning students (Siman Ning, Haoyu Yue, and Chin-Wei Chen), and a Master of Urban Planning candidate (Richard McMichael). This report examines the successes and lessons learned from existing high-speed rail projects in Europe and Asia, including 50 hours of interviews…

Higher Depression Risks in Medium- Than in High-Density Urban Form Across Denmark
Chen, T.-H. K., Horsdal, H. T., Samuelsson, K., Closter, A. M., Davies, M., Barthel, S., Pedersen, C. B., Prishchepov, A. V., & Sabel, C. E. (2023). Higher depression risks in medium- than in high-density urban form across Denmark. Science Advances, 9(21), eadf3760–eadf3760. https://doi.org/10.1126/sciadv.adf3760
Abstract
Urban areas are associated with higher depression risks than rural areas. However, less is known about how different types of urban environments relate to depression risk. Here, we use satellite imagery and machine learning to quantify three-dimensional (3D) urban form (i.e., building density and height) over time. Combining satellite-derived urban form data and individual-level residential addresses, health, and socioeconomic registers, we conduct a case-control study (n = 75,650 cases and 756,500 controls) to examine the association between 3D urban form and depression in the Danish population. We find that living in dense inner-city areas did not carry the highest depression risks. Rather, after adjusting for socioeconomic factors, the highest risk was among sprawling suburbs, and the lowest was among multistory buildings with open space in the vicinity. The finding suggests that spatial land-use planning should prioritize securing access to open space in densely built areas to mitigate depression risks.
A House Deconstructed

Summary
We would like to think that we ‘know’ what goes into making a modern building. But the truth is that no one, not even architects, knows. The OUR [Office for Uncertainty Research] spent three years studying a single, relatively modest modern house located in Seattle, WA. The research focused on four vectors: Atomic Consciousness that dates back to the Big Bang and the earliest Super Novas: Production Consciousness that involves a vast array of ingredients that are combined to make architectural products: Labor Consciousness that spans a wide spectrum of temporal and economic conditions; and Source Consciousness that is multilayered and global in its reach. Though much was learned, it became clear that a huge proportion of what we ‘know’ about the house was unknowable, not because our epistemological instruments aren’t strong enough or calibrated precisely enough, but because things themselves are indeterminate, uncertain. This begs the question about agency. If we are to critique our profession and even improve some of its claims about Sustainability, then we must develop a more robust understanding of the building industry and the sourcing and making of materials. We must even develop a stronger awareness of the history of atoms and how architecture brings that history into a remarkable focus.
Scaling Down from the Neighborhood in Urban Planning Research and Practice: The Potential Benefits of a Micro-Scale Focus
Walter, R. J., Tillyer, M. S., Ramiller, A., & Acolin, A. (2023). Scaling Down from the Neighborhood in Urban Planning Research and Practice: The Potential Benefits of a Micro-Scale Focus. Journal of Planning Education and Research. https://doi.org/10.1177/0739456X231175593
Abstract
The neighborhood has been the dominant spatial unit in urban planning since the early 20th century. Criticisms of the neighborhood unit include disagreements about defining boundaries, methodological challenges in capturing neighborhood effects, and negative impacts on communities. With advancements in data management, and public data available at smaller units (street block or property), quantitative analyses are possible at the micro-scale. This commentary draws on crime research and prevention to illustrate the benefits of micro-scale approaches to quantitative analyses in the field of urban planning, arguing that the devolution to smaller scales may be a vehicle for efficient resource allocation.
