Passive House design and construction is a team sport. It requires effective strategies and cooperation, but also precision in the field and the ability to tweak and recalibrate systems once the building is complete. A robust envelope may be the superpower of Passive House construction, allowing for downsized mechanical systems, electrification, and reduced stress on the energy grid, but these benefits are only achieved if everything works as intended.    In this episode, host Zack Semke shares selected clips of conversations from the Reimagine Collective. Featured speakers include Carmel Pratt of ZAZNRG and Passive House New York on post-occupancy data, Ed May of bldgtyp on modeling literacy, Skyler Swinford of Energy Systems Consulting with Lloyd Alter of Toronto Metropolitan University on refrigerants and water-based distribution, James Peterson of Petersen Engineering on heat pump water heaters, and Nick Nigro of Leggett McCall on what's next at the innovative and enormous Bunker Hill housing redevelopment project.The Reimagine Edit is a special series of the Passive House Podcast that shares curated insights from our Experts-In-Residence at the Reimagine Buildings Collective, our membership community of building professionals stepping up to tackle climate change.

In this episode of the Passive House Podcast, Mary James and Ilka Cassidy speak with Joel Callow, building physicist and founding director of UK consultancy Beyond Carbon, about scaling certified Passive House delivery in London. Callow explains the firm's focus on whole life carbon, compact building forms, overheating avoidance, and early-stage design input, and notes the team has grown to 12 people with recruitment challenges as UK training ramps up via the Passive House Trust. He describes Beyond Carbon's role in helping major developer Barratt adopt Passive House—through lobbying, 12–18 months of R&D, and cost and constructability work—leading to thousands of units in the pipeline and an estimated 15–20,000 London dwellings in progress.https://www.beyondcarbon.uk/Thank you for listening to the Passive House Podcast!

TIME Magazine - Enertia® Homes Their Company Slogan - "Your House Should Take Care of You......... Not the Other Way Around!" My spotlight is on Green Living Because of A LOT of Talk this Year About Global Warming & the Eco-System.Enertia Homes recieved an Energy Efficiency Award from the US Department of Energy. Enertia® Homes use an ingenious design, and the science of materials, to heat and cool buildings without fuel or electricity. Fitted with Photovoltaic panels, and a metal seamed roof, homes can be self-reliant for heating, cooling, electricity, water and food. This is a modern Building System, an integrated group of innovations and a construction technique so basic, yet amazing and effective, it has been called a Modern Marvel- A Time Magazine Invention of the Year & Zayed Future Energy Prize, "Innovative Structure of the Century Award", AWPI Century's Best Award. These are not conventional “stick-frame” single-generation houses. The walls are solid wood, and the design life is hundreds of years. Comfort is by design and from a unique structural material, not from a mechanical/ electric compressor or furnace. The roof can generate electricity and capture water. The sun space harvests energy, and in it you can harvest food. Most have a built-in "biosphere" modeled after planet Earths' that draws energy from the sun, and geothermal stability from the ground, creating a temperate climate that buffers the primary living space. Your personal Greenhouse Effect warms your house in winter. Naturally-induced air currents cool it in summer. "When we started 30 years ago the terms Bio-mimicry, Green Building, Carbon Sequestration, and Life-Cycle Analysis did not exist. Enertia® homes pioneered these goals that others are still striving to achieve." ~ Enertia.com © 2026 All Rights Reserved© 2026 BuildingAbundantSuccess!!Join Me on ~ iHeart Media @ https://tinyurl.com/iHeartBASSpot Me on Spotify: https://tinyurl.com/yxuy23baAmazon Music ~ https://tinyurl.com/AmzBAS

In this episode of The Passive House Podcast, Zack Semke chats with Nick Nigro of Leggat McCall about the Bunker Hill Housing Redevelopment in Charlestown, Boston, a phased replacement of 42 aging WWII-era public housing buildings into 2,699 mixed-income units. Nick explains how the team committed to Passive House from day one and is using a repeatable “kit of parts”—precast lateral-load-bearing cores, prefabricated load-bearing exterior panels, and CLT floor systems—to improve speed, reduce temporary work, and lower both carbon and cost through iteration across 15 buildings. He describes early modeling, enclosure mockup testing, and construction-sequencing innovations like using the permanent elevator as a hoist. https://passivehouseaccelerator.com/articles/critical-mass-scaling-passive-house-at-bunker-hillhttps://www.lmp.com/Thank you for listening to the Passive House Podcast!

There's a lot of building science that goes into making passive buildings extremely durable, efficient, comfortable, and healthy. However, one of the things that often gets overlooked when trying to explain the benefits of Passive House is the experience of actually being in one. There is a certain ineffability associated with the experience that defies easy translation into facts and figures, and this can be especially tricky to communicate to clients who are not already enthusiastic about Passive House.

Send me a messageWhat if the biggest barrier to decarbonising buildings isn't technology, cost, or ambition - but sheer complexity?The built environment produces nearly 40% of global emissions, yet we still make low-carbon construction harder than it needs to be.In this episode, I'm joined by Tommy Linstroth, founder of Green Badger, to unpack why construction remains one of the most overlooked climate battlegrounds, and why that's a mistake. We dig into LEED v5, embodied carbon, and the growing gap between climate ambition and what actually happens on building sites. The stakes are huge: buildings lock in emissions for decades, sometimes centuries.You'll hear why builders aren't resisting sustainability, they're drowning in shifting standards, paperwork, and fragmented data. We explore how LEED has evolved, why carbon now sits at the centre of green building standards, and how decisions made at the design stage quietly determine emissions for the next 100 years. Tommy also explains why third-party verification matters, how “build to code” often means “barely legal”, and why retrofitting existing buildings may be the hardest climate challenge nobody likes talking about.We also dig into where genuine momentum is emerging - from falling renewable costs to better data and smarter software, and how climate tech, including AI, could finally make the low-carbon choice the easy choice. If net zero, emissions reduction, and the energy transition are serious goals, then construction can't stay a side quest.
