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.

Mary James and Ilka Cassidy talk with Meleny Thomas, executive director of the South Baltimore Community Land Trust (SBCLT), about the organization’s mission to create community-led development and her decision to target Passive House for their initial development of 10 new homes. The choice sets a precedent for healthy homes not being restricted to affluent communities, Thomas says, in discussing how she first heard about Passive House and why she chose it as a target. SBCLT grew out of a decade of grassroots and youth organizing in a community burdened by unsafe, unaffordable housing and toxic environmental hazards. Thomas has more than 15 years of experience building community-based organizations and serving families and has a Master’s in nonprofit management and leadership.Find links to upcoming events here: https://passivehouseaccelerator.com/articles/passive-house-week-in-preview-june-13Thank you for listening to the Passive House Podcast!

Sixteen years in the UK Royal Navy not only gave John Palmer a sounds background in engineering, he also gained leadership and management experience within a large and structured institution. When he made the decision to leave his Commander role, he retrained and applied his technical and management skills to building and then energy efficiency. It was only a matter of time that he came across and then fully embraced the building science of Passive House. In 2018 he left his role as Managing Director of Enhabit to become the Research and Policy Director for Passivhaus Trust.

On Episode 37 of the Passive House Podcast, 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.Mary, Ilka, Matthew Cutler-Welsh, and Zack Semke discuss upcoming events that can be accessed here: https://passivehouseaccelerator.com/articles/passive-house-week-in-preview-may-3Thank you for listening to the Passive House Podcast!

On Episode 36 of the Passive House Podcast. 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. (She’ll expand upon these ideas at our Passive House Summit on Monday, April 26, too!)

In Episode 35 of the Passive House Podcast, cohost Zack Semke interviews architect Tom Eisele, recently of the New York City Mayor’s Office of Resiliency, and current policy advisor with New York Passive House. Zack and Tom discuss the momentous New York City Local Law 97 which caps greenhouse gas emissions for all buildings in New York that are 25,000 or larger—over 50,000 buildings. The caps step down to 80% reduction in GHGs by 2050, with hefty fines to be levied on building owners for buildings that do not comply. Local Law 97, assuming it persists, will compel all significant buildings in New York City to dramatically reduce energy consumption and emissions over the coming decades, and building owners will be looking for predictable and quantifiable means to achieve these reductions. Enter Passive House. This podcast interview previews ideas and themes that will be explored at Passive House Accelerator’s Passive House Policy Summit to be held on Monday, April 26, 2021.

Ya’el Santopinto is an architect and associate at ERA Architects, where she leads ERA’s affordable housing retrofit practice. She is also the director of research and partnerships with the Tower Renewal Partnership, a non-profit sister organization to ERA that advocates for supportive policy frameworks around the preservation of Canada’s affordable apartment housing supply. Ya’el is the project architect on the inspiring Passive House retrofit of the Ken Soble apartment tower in Hamilton, Ontario—the largest EnerPHit outside of Europe.Mary James and Ilka Cassidy spoke with Ya’el about urban policies and the shape of cities, tower renewal, and the preservation of vital rental housing. Today about 800,000 Canadian households live in aging tower structures, which were built starting in the 1960s to accommodate post-war families. Tower renewals transform more than the buildings, as they breathe new life into the tight-knit communities that have sprung up in them, Ya’el points out. Taking a Passive House envelope-first approach to such retrofits creates a win-win-win for residents’ comfort, carbon savings, and for landlords. Listen in for more about ERA’s retrofits-only practice, its collaborative systems approach, and the primary research conducted by its sister organization, the Tower Renewal Partnership.
