This episode is all about a retrofit programme gone wrong in Preston and the effort required to fix it. It's a story that was covered in the pages of Passive House Plus back in 2018 under the headline "Disastrous Preston retrofit scheme remains unresolved" and until recently we thought it remained unresolved.We're joined by Filipe Amarante and Joanna Curtis to talk about the Preston Retrofit Catastrophe and all the work that National Energy Action has been doing to fix the grotesque damage that was wrought on a community in the 2010s. It's a project that's consumed at least four years and—in truth—will require many more to make good.It's not a hopeless story though. The work NEA has carried out is full of lessons for anyone who works in retrofit to learn. They've taken a worst case scenario—one so bad it's hard to imagine how you could make it any worse—and developed a remediation programme that mitigates the worst of the situation while laying out a best-practice template for how one should approach place-based retrofit programmes.They're also hosting a NEA webinar about the programme on 10 June: sign up here.Notes from the showThe Passive House Plus article: "Disastrous Preston retrofit scheme remains unresolved"Filipe on LinkedInJoanna on LinkedInThe NEA website The NEA's summary report on the project (and video): Warm and Safe Homes in FishwickMore photos of the disaster in "When retrofit goes wrong – lessons from Preston", a presentation by Kate de Selincourt, the writer who brought this story to Jeff's attentionCathy Come Home on IMDBA Taste of Honey on IMDBRiff-Raff on IMDB **SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

Send us a textWhat happens when award-winning architects and builders challenge the notion that sustainable, high-performance buildings must sacrifice aesthetics? This thought-provoking conversation brings together Passive House experts who are transforming New Zealand's built environment through buildings that are both beautiful and functional.Architect Rafe Maclean shares how client feedback about a poorly-performing design prompted his journey into building science, while Joe Lyth reveals the heartbreaking reality of watching his children develop respiratory issues in cold, damp rental properties. Builder Josh Atkins describes his frustration with energy-inefficient new homes that cost homeowners thousands in ongoing expenses. These personal stories highlight why performance isn't just about sustainability—it's fundamentally about health and comfort.The guests dismantle common misconceptions about high-performance buildings, particularly the idea that Passive House certification requires boxy designs with minimal windows. Through their work, they demonstrate how constraints often generate more creative, thoughtful architecture. As Joe explains, "If you've got a blank canvas you can do anything, and you don't necessarily need to judge all your decisions." The discussion explores how early collaboration between architects, builders and clients allows performance requirements to enhance rather than limit design possibilities.Perhaps most compelling is their suggestion to shift terminology—referring to conventional construction as "low-performance buildings" rather than elevating better practices as "high-performance." After all, would anyone willingly purchase a "low-performance refrigerator" that might spoil your food? This reframing helps normalize better building standards as baseline expectations rather than premium add-ons.Ready to experience architecture that looks beautiful and actually works?

In this episode of the hosts Mary James and Jay Fox sit down with Vincent Bergeron, an architect with Equipe A Architects in Quebec, to explore The Monarch—a groundbreaking social housing project in Sherbrooke. With 134 units guaranteed affordable for 35 years, this high-rise development is notable not only for its scale but for its ambitious pivot toward Passive House principles. Van shares how a tight timeline, a challenging site, and a collaborative team led to innovative choices in prefabrication, envelope design, and energy efficiency. Hear how a late-stage decision to pursue Passive House certification helped shape a healthier, more resilient living environment for low-income families, all while keeping costs in check.https://equipea.ca/

In this seventh episode of The Reimagine Edit (TRE) series of the Passive House Podcast, host Zack Semke shares selected clips of insights from Jessica Grove Smith (Joint Managing Director of Passive House Institute), Mark Attard, Rainger Pinney, John Loercher, Galen Staengl, Mike Fowler, Cait Eggers, Sean Velez, Nidhi Shaw, and Lloyd Alter.Quotes:"Walking off the ferry in Seattle and ashes falling out of the sky—that changes your perspective. The same thing with the heat dome and with COVID. These events over the last seven to eight years have reshaped how I think and approach design and architecture, and now my focus is on resilience." — Mike Fowler"If you touch any one single component, make sure you go all the way. That's the only way you're going to future-proof your building and have a long-lasting carbon emission impact." — Jessica Grove-Smith"It's very clear that what typologies get built follow where there's grant money. Developers are happy to build anything as long as it comes with a little extra funding—that's a powerful lever we can use to shape the built environment." — Rainger Pinney"In Passive House buildings, humidity changes very slowly. That just observation applies in any climate—you're less affected because the air isn't running through your building like it does in most buildings." — Galen Staengl"We should be retrofitting schools rather than demolishing them. Roofs, windows, and wall cladding can be replaced; we don't need to demolish the whole school to make it better." — Nidhi ShahThe 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.

Joining us for this episode are Tom Cox and Sally Sattary co-founders of Decent Energy. They have a software startup borne of a retrofit experience that did not meet its homeowner expectations, a proprietary software that works to maximise the value of battery storage to improve two key metrics: reducing cost of electricity and reducing the carbon intensity of the energy you do use.There's a bunch of chat about the potential of decentralised energy management to help people in all sorts of ways, from reducing one's individual impact to helping the grid cope with occasionally, dangerously abundant renewable energy—an issue which costs every household something like £40 per year, just to turn off the generation facility let it overload the grid.Anyway, there's loads in there.

We break down what it actually means for architects to commit to sustainability and discuss the state of climate commitments in architecture and beyond. We talk about how firms are measuring up to the AIA 2030 Commitment, the gaps between goals and actual progress, and, of course, what needs to change if we want to hit those looming 2030 and 2040 climate milestones. Dan shares his insights into how sustainability has evolved from a niche interest to a central concern in architecture, as well as why some states and firms seem to be going faster than others in energy efficiency. We also talk about the commitments made by mechanical and structural engineers, contractors, and manufacturers because, after all, sustainability isn't just an architect's responsibility; it's an industry-wide effort. Along the way, we touch on the role of building codes, the impact of energy modeling (or lack thereof), and why some firms are struggling despite their best intentions, and, of course, we confront the big question: are we actually on track to meet net-zero goals, or are we just going through the motions? Dan shows how industry climate commitments help track progress and drive real change, even though there's still a lot of work to do. Moving forward, shifting laws and market trends should keep shaping sustainability efforts, with regeneration and adaptation playing big roles. If you are an architect, engineer, or just someone wondering what real climate action looks like in the world of architecture, then this episode is definitely for you. Time stamps: [02:09] - Dan reveals that his passion for sustainable architecture began in childhood and led him to become FX Collaborative's director of sustainability. [04:36] - The world is far from meeting Paris Climate Agreement targets, with U.S. climate funding looking at setbacks. [07:57] - Dan points out how the AIA 2030 commitment pushes firms to design net-zero buildings. [11:03] - In 2023, 61% of projects used energy models, but they only slightly outperformed non-modeled ones. [13:04] - Various industry commitments focus on carbon reduction. [16:06] - Dan argues that clients increasingly consider firms' climate commitments. [17:42] - Dan explains that, in 2023, 490 companies reported nearly 25,000 projects, with 10% meeting the 80% reduction target. [20:08] - Ruben Hall, a nearly complete Passive House retrofit, exemplifies energy-efficient building conversion in NYC. [23:18] - The 2030 memo outlines project goals, ensuring alignment with the commitment to energy efficiency. [25:44] - Dan explains how daylight dimming systems and LED fixtures enhance energy efficiency. [27:38] - Rapid environmental policy changes such as Local Law 9 stress the need for sustainability strategies focused on the future. [28:58] - Dan argues that the future of sustainability is in regeneration. Links / Resources:Guy Geier Instagram | Twitter Dan's LinkedIn Page

This time around we're talking about the UK Net Zero Carbon Buildings Standard (UKNZCBS) with three of its architects: Jess Hrivnak (RIBA), Jane Anderson (ConstructionLCA), and Julie Jodefroy (CIBSE).The UKNZCBS is the first cross-industry standard for net zero carbon-aligned buildings, albeit in a pilot form. The standard has been developed to enable stakeholders to prove whether a building aligns with the UK's carbon and energy budgets by providing a single, agreed methodology for defining what ‘net zero carbon' means for buildings in the UK.This probably won't be the only episode we'll produce on the subject and we'll be watching its progress with great interest.  Notes from the showThe UK Net Zero Carbon Buildings Standard websiteThe UK Net Zero Carbon Buildings Standard on LinkedInJess Hrivnak on LinkedInJane Anderson on LinkedIn Julie Godefroy on LinkedInA Passive House Plus article about UKNZCBSA story about the greenest Sainsbury's ever**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**
