In this Encore Episode of the Passive House Podcast (originally aired as Episode 29 on International Women's Day, March 7, 2021), guest co-hosts Mary James and Ilka Cassidy interview two exciting guests who are collaborating on a retrofit guide for common building typologies found in cold climates. Nina Sharifi is an assistant professor at Syracuse University’s School of Architecture and the Director of the Applied Sciences and Technology Research and Architecture Lab. Gabrielle Brainard is an architect, facade specialist, and educator. She consults on Passive House projects, conducts academic research, and teaches architecture and building science at Pratt Institute and the Columbia Graduate School of Architecture, Planning, and Preservation.The envelope retrofit guide that they are collaborating on will provide technical guidance to architects in the early stages of net-zero retrofit projects. The guide focuses on the building envelope, a critical component of high-performance retrofits that is the primary responsibility of the architect. During their interview with Mary and Ilka, Nina and Gaby discuss the retrofit guide project, dive into an explanation of the field of architectural sciences and how Passive House design meshes with it, and explore the overlap of architecture, construction, and technology in Passive House project delivery. They also reflect on their experience as women in the fields of architecture and construction, and in working to catalyze the transition to high-performance, low carbon building. Mary, Matthew Cutler-Welsh, and Zack Semke mention upcoming Passive House Accelerator programming for September, including: The Global Passive House Showcase (formerly known as the Global Passive House Happy Hour): https://passivehouseaccelerator.com/articles/our-happy-hour-to-become-the-global-passive-house-showcaseConstruction Tech Tuesday: https://passivehouseaccelerator.com/articles/construction-tech-is-back-soonThank you for listening to the Passive House Podcast!

In this Encore Episode of the Passive House Podcast (originally aired as Episode 37 on May 3, 2021), guest co-hosts Mary James and Ilka Cassidy interview Katie Faulkner, founder of WestFaulkner, an office with a mission for sustainable design. She is also a director at PT-Tech, a division of Placetailor in Boston whose initial focus is on the design and prefabrication of retrofit panels for triple-decker homes.Katie has been working as an architect for more than 20 years and was named to the American Institute of Architects College of Fellows in 2020. Her work is motivated by an interest in sustainable, modular construction, centered on the intention to reduce risk and improve cost control. She was a founding partner of the Boston-based firm NADAAA, where her projects included the Daniels Building at University of Toronto, Rhode Island School of Design’s North Hall, and the R+D Center at the Beaver School. More recently, she was a Vice President of Design for Katerra, focusing on a mid-rise mass timber housing prototype.Mary and Ilka’s conversation with Katie ranges from the career opportunities that prefabrication opens up for women to the urgency of deep energy retrofits, and much in between. Her early work in healthcare design led to an abiding interest in optimized project delivery models, while always keeping sustainable design front and center. Katie’s decades-long experience is well suited to her current collaboration with Placetailor to bring to market cost-effective bio-based retrofit panels.At the end of this encore episode, Mary, Matthew Cutler-Welsh, and Zack Semke discuss major Passive House conferences and events coming up in Fall 2021: 25th International Passive House Conference (Passive House Institute) Part I: September 10-12; Part II: September 14+15: https://passivhaustagung.de/en/Tower Retrofit Symposium 2021 (Passive House Canada) September 22-23: https://www.passivehousecanada.com/tower-retrofit/PhiusCon (Phius) October 12-15: http://phiuscon.org/South Pacific Passive House Conference (PHINZ + APHA) November 25-27: https://passivehouse.nz/2021/06/09/spphc21-cfa/Thank you for listening to the Passive House Podcast!

In this Encore Episode of the Passive House Podcast (originally aired as Episode 36 on April 26, 2021). cohost Matthew Cutler-Welsh interviews Robyn Wark, Manager of Advanced Demand Side Management at BC Hydro about the groundbreaking Energy Step Code in British Columbia. Robyn is a sustainability strategist, partnership builder, and coach on low carbon communities. Her sustainability work has won awards from Real Estate Foundation of BC, the Federation of Canadian Municipalities, the Canadian Institute of Planners, and the Planning Institute of British Columbia (PIBC). In 2013 she was awarded the PIBC Individual Award for Leadership in Advocacy & Innovation. The BC Step Code provides a roadmap of 5 steps to guide the AEC industry and BC cities from today's base building code to an endpoint of Passive House-levels of performance. This highest level of performance, “Step 5”, will become mandatory for all buildings in British Columbia by 2032. Because everyone knows exactly where code is headed, as well as the steps to get there, early adoption of higher levels of performance can be incentivized in a clear and rational way. In her conversation with Matthew, Robyn describes the BC Energy Step Code, how it came to be in British Columbia, and how its lessons might be applied elsewhere in the world.
