As the topic of embodied carbon in building materials has gained popularity in the design industry, we are often presented with fascinating data and statistics on the subject. This leaves us with an important question: how are industry leaders actually dealing with this issue in practice?

Building on Embodied Carbon Part 1: The Blind Spot in the Building Industry, Part 2 presents a panel of speakers with varied backgrounds to discuss:

  • The types of Life Cycle Analysis (LCA) that are utilized in practice

  • When an LCA is integrated into the design process

  • How the study of embodied carbon affects the workflow between architects, engineers and contractors

  • Precedent projects where LCA has guided important design decisions

Kieran Timberlake


Stephanie investigates the interaction between constructed and natural environments, focusing on green infrastructure, urban ecology, high-performance landscape design, Life Cycle Assessment, material health and toxicity, and environmental modeling and mapping. She has piloted spatial surveys of Love Park and the Emergency Department at Jefferson University Hospital, and led the materials database development for Tally®, a custom LCA application that allows architects to calculate the environmental impacts of their building material choices. She has brought her expertise to projects such as the US Embassy in London, the Consortium for Building Energy Innovation, and a new art gallery administration building. 
Stephanie's writing on life cycle assessment was published in the book Embodied Energy and Design in 2017, and her award-winning research on green roofs has appeared in Cities and the Environment (CATE) and Green Roof Ecosystems. Stephanie also serves as a lecturer of Urban Ecology at the University of Pennsylvania School of Design and is the Co-Editor-in-Chief of Scenario Journal, an online publication devoted to showcasing and facilitating the emerging interdisciplinary conversations between landscape architects, urban designers, engineers, and ecologists. She has spoken and served on juries at Columbia University, Cornell University, Yale University, the University of Pennsylvania, the University of Southern California, and Wesleyan University. 


Stacy Smedley, with a degree in Architecture from the University of Washington, in Seattle, is the architect behind the extension of the Bertschi School Science Wing in Seattle, USA. The Science Wing has been certified as the world's fourth Living Building - making it a giant step on the Journey to Deep Green and the greenest Skanska building project to date. Stacy Smedley decided to join Skanska after getting to know the company that realized her vision.

Buro Happold


Julie Janiski leads integrated high-performance building design teams at BuroHappold Engineering. Her key interest is to align the process and results of technical analysis to solutions that enhance design, building performance, and ultimately the health, wellness, and experience of the building by occupants and visitors.


Julie’s recent work includes multiple commercial projects in the Boston Seaport with WS Development, a high-performance corporate headquarters campus in Baltimore for Under Armour, a number of new office buildings for U.S. Embassy projects internationally for the U.S. State Department, an integrated “roadmap” plan to reduce greenhouse gas emissions 80% by the year 2050 (80×50) for the City of New York, and The House at Cornell Tech – a residential high-rise in New York City which is certified Passive House and LEED Platinum.


Julie received a Master of Architecture from the University of Michigan and a Master of Design Science in Sustainable Design from the University of Sydney and is an adjunct assistant professor at Columbia University as well as a visiting critic at a number of other universities.
