Andrew Waugh is founding director of the British firm Waugh Thistleton Architects. The core ethos of the practice is to design and construct sustainable, beautiful buildings. Waugh Thistleton work to find the most efficient, aesthetic and ambitious architectural solutions that require the least resources.Past built projects include Murray Grove; the World’s first all timber residential tower. Andrew’s passion for architecture extends beyond the physical practice to a wide-ranging research in sustainable construction - for which he won the RIBA president’s medal in 2010 and upon which he continues to write, teach and lecture at every opportunity. Andrew is an internationally sought-after speaker, writes for numerous industry publications and teaches at the World’s best architecture schools. He is also an active member of various organisations committed to a sustainable world. Andrew is a visiting Professor of Architecture at the University of Arkansas.

John Klein is the CEO of Generate Technologies: a Boston-based, MIT-spin off company with the mission to digitize one of the world’s largest and least digital industries: the 12-trillion-dollar Architecture, Engineering, and Construction (AEC) sectors. Generate is developing a technology platform for architects, to transform the way buildings are designed and built. Generate’s technology is designed to tackle the global climate and housing crises, by accelerating the deployment of cost-effective, sustainable building materials and systems, like mass timber.

Prior to MIT, Klein worked for Frank Gehry, Greg Lynn, Mark Burry and Zaha Hadid for eight years, leading the design and delivery of over 10,000,000 sf of construction. As Senior Architect, he implemented advanced technologies to streamline the design and construction of the IT Tech Park in Chennai, India, the Glasgow Transportation Museum, and The Seoul World Design Park. In Beijing, Klein oversaw the construction of the Wangjing Soho Skyscrapers—the largest Zaha Hadid project to date completed in record speed due to the integration of computational tools that linked design to supply chain. Klein is a US Registered Architect, and holds a professional Bachelor’s of Architecture from SCI-Arc and a Master’s of Science from the MIT Media Lab.

Stephanie Carlisle is a Senior Researcher at the Carbon Leadership Forum where she leads collaborative development of open-access LCA data, tools, and methods to support the building sector in radically decarbonizing construction. Her work brings together diverse stakeholders from industry, land management, manufacturing, labor, policy and design to find new approaches to climate justice. Prior to joining the CLF, she was a Principal at KieranTimberlake where she helped develop Tally, a whole building LCA tool and worked to implement strategies that address climate and health impacts of building materials. She is Co-Editor-in-Chief of Scenario Journal, and a lecturer at the Weitzman Schools of Design at the University of Pennsylvania where she teaches courses in life cycle assessment, building materials, and urban ecology. She currently serves on the Steering Committee for US Architects Declare a Climate, Justice, and Biodiversity Emergency, a climate action group pushing for radical change in architectural practice and education.

Heather Holdridge, LEED Fellow, EIT, Assoc. AIA, is the Sustainability Director at Lake|Flato Architects, a firm that has gained national recognition for architecture that responds to its particular place while seamlessly integrating with the natural environment. Leveraging her background in mechanical engineering, Heather directs all Lake|Flato project teams in establishing sustainability goals.
