    Death Of The Suburbs: An Urban Manifesto

    Death Of The Suburbs: An Urban Manifesto

    It’s time to fundamentally reevaluate the way we build - not just at the level of detailing, but at the scale of the city. What are the decisions we make about density and how do they affect our daily lives? Why do we orient our urban infrastructure around cars when they’re incredibly inefficient ways to move people around? Why can’t you get to 90% of your daily needs within a 15 minute walk? Join Kristof as he interviews Ruchi Modi of the architecture and urbanism firm, PAU on a range of topics exploring how urban environments (can and will) actually benefit the entire planet.

    Carbon Fluency

    Carbon Fluency

    Architects and engineers have great power because they make decisions that influence resource and energy use in their buildings. With great power comes great responsibility and now is the time to become fluent in the language of embodied carbon. In this episode Kristof has a lively conversation with Z. Smith and Kelsey Wotila from EskewDumezRipple on this and some adjacent topics.

    The Insulation Decision

    The Insulation Decision

    While insulation and airtightness are critical elements of a high performance building, they also can significantly increase the risk of health and moisture failure issues. In addition, if using high "embodied carbon" impact materials then high performance buildings can have a higher net carbon impact by 2050 than conventional buildings. Come join us to learn how to create truly healthy, durable, comfortable, and low carbon impact buildings. Join Kristof as he interviews Lucas Johnson in a discussion about the impacts of insulation material decisions.


    Lucas is a building scientist who has worked as a builder, utility program manager, enclosure systems consultant, and clean tech venture capital consultant to deliver Zero Net Energy, Passive House, Living Future, and even two of his own standards: SUN Buildings and Active House. Lucas holds a degree in Physicochemical Biology as well as a Master of Environmental Science and EcoEntrepreneurship. His position at 475 is his dream job since he gets to share his experience by collaborating with architects, engineers, and builders to make their projects cost-effective, carbon negative, healthy, durable, and enjoyable.

    The V In HVAC - Part 2

    The V In HVAC - Part 2

    As houses get tighter, we know they need to be ventilated (hopefully). But many in the building industry don’t understand ventilation well. We know about the less than ideal ways to do it, like raw fresh air intakes. We’ve heard of ERVs. And it seems like everyone thinks they want them, but nobody understands them or cares enough to actually bring them into a project. Well wonder no more friends. This episode is a two part series and a deep dive into the V in HVAC - demystifying the ventilation paradigm and making ERVs a topic you can wrap your head around after a few listens.

    Don’t be afraid to rewind. Soak it up. Join Kristof as he interviews Chris Smith of Zehnder America about ERVs, HRVs, and all things ventilation.
