Zero Ambitions Podcast

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**

We are joined by Valentina Marincioni (UCL, UKCMB) and returning guest Toby Cambray (Greengauge) to talk about the bane of all buildings: moisture.Recently, they they've produced a simple explainer video about "breathability" in buildings for the UK Centre for Moisture in Buildings. Given Jeff's proclivity for referring to the 'sweatability' of buildings this seemed like a perfect opportunity to have Toby back and meet his colleague Valentina.We got into the subject of moisture in some depth, discussed the key terms (vapour diffusion, hygroscopicity, and capillary action), why this all matters, what's important to understand and how it's easily misunderstood and easily miscommunicated.We also play the audio from the video.Notes from the showBuildings Don't Breathe, the video that led to the conversationToby on LinkedInValentina on LinkedInThe UKCMB website and the tools and guidance they host thereThe recent Historic England paper: Air and Vapour Control Layers (AVCLs) in buildings of traditional construction.

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. You can find Decent Energy, Tom, and Sally in all the usual places (links below).Notes from the showTom Cox on LinkedInSally Sattary on LinkedInDecent Energy's websiteDecent Energy on LinkedInSaul Griffith's website - an author who inspired Tom to work on the problem of energy decentralisation and demand decarbonisation**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**

This episode is a window into the consumer side of domestic retrofit that's full of lessons for everyone involved in the retrofit sector. We speak with retrofit influencer Judith Leary Joyce about the experience of undergoing a deep retrofit and learning how to communicate about the subject with normal people. She talks us through her journey from building an extension during the pandemic to getting deep into retrofit and eventually becoming an unlikely retrofit influencer.Whether you work in a domestic, commercial, or industrial setting the nature and needs of normal people will remain the same, so this is an episode full of lessons and insights for anyone  for anyone involved in domestic retrofit about:- how to speak with normal people- how to learn how to do better (TLDR: listen to yourself, or get someone to listen to you to check whether you're baffling your customers)- how to think about their needs and understand their perspectives- how to inspire them and inform them better prior to a projectShe's also got some fascinating insights about when people are likely to be able or willing to listen to someone talking about building performance and taking on new ideasNotes from the showJudith on LinkedInJudith on InstagramJudith on FacebookJudith on TwitterJudith on LinktreeJudith's Eco Renovation Home websiteBeginner's Guide to Eco Renovation: Understand the Basics and the Best Questions to Ask by Judith Leary Joyce (I couldn't find a properly independent bookshop stocking it)**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**

For this episode we were joined by Nathan Gambling. For those that are new to him, he's heating engineer of some repute, a renowned educator, and a fellow podcaster.  The episode revolves around the nature of education and learning, the skills gap—specifically focusing on heat pump and retrofit education—and a post that Nathan put up a few weeks ago about an educational experiment he tried out that led to us thinking about the purpose of education.In essence, the episode is about how people learn and how this should shape our approach to meeting the skills gap. Nathan is a great communicator and you should check his podcast.Notes from the showNathan Gambling on LinkedInBetaTalk - The Renewable Energy and Low Carbon Heating PodcastNathan's recent LinkedIn post about his teaching experiment Nathan's old LinkedIn repost about that weird arrangement of radiators That Gatsby report we talk about: Closing the Retrofit GapBetaTalk episode: How boiler engineers transition to heat pumps**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**

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**

Last year the Royal Institution of Chartered Surveyors (RICS) released its residential retrofit standard. Given that they're one of the construction industry's oldest, largest, and most influential institutions this felt significant.Importantly, the RICS organisation has a global footprint, so it has the potential to influence good behaviour far and wide. We're also hopeful in light of the success of the RICS Whole Life Carbon Assessment standard. That is in terms of its apparent impact, adoption, and reach.In order to get into the subject a bit more we invited Paul Bagust (Head of Property Standards), Steven Lees (Senior Specialist - Residential Survey), and Robert Toomey (Senior Public Affairs Officer) to join us to talk about the standard and the impact they want to see it have.Notes from the showPaul Bagust on LinkedInSteven Lees on LinkedIn Robert Toomey on LinkedInThe old Passive House Plus article about the Preston retrofit catastrophe that Jeff mentionsThe RICS consumer guide to energy will be here once it's published (one for the listeners of the future) The website for Scotland's Green Home Festival – details for 2025 are incoming**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**

Can we address the decarbonisation of homes by focusing on health? That's the mission that Jenny Danson has set for herself in establishing Healthy Homes Hub, and it's a question that manages to subvert Betteridge's Law of headlines, too.  Healthy Homes Hub is a network, built around an online platform, that's dedicated to transforming the way people experience social housing, and its environmental impact, by creating healthier housing environments. Comprising a series of eight dedicated hubs that cover everything from policy and finance, to retrofit and air quality, the platform enable easy access to important information, insights, and thought leadership.Jenny has over 25 years of experience in social housing, as a supplier and client-side, driving innovation, delivery and improving lives so she knows what she's talking about.The project was borne of a frustration with seeing time and effort wasted as people across the sector carry out the same kinds of work, repeatedly, starting from scratch when they could share resources and pool experience. In a sector where capacity is in short supply this time could be easily put to better use.We talk through the challenges faced by the sector and how a focus on people and health can be used to drive us towards delivering on decarbonisation targets, but train our attention on outcomes for the people living in the 'building assets' not just the performance of the fabric and technology that comprises their home.While it's explicitly aimed at the social housing sector, the platform offers a wealth of information resources and sharing of experience that could be useful far beyond the provision of social housing.Notes from the showThe Healthy Homes Hub websiteJenny on LinkedIn Healthy Homes Hub on LinkedInOperational excellence in social housing - a roundtable readout Those ventilation papers that Jeff mentionedVentilation and Indoor Air Quality in Part F 2006 Homes (BD 2702) by S.

Joining us on Zero Ambitions this week is Chris Carus co-founder of Loco Home Retrofit, a Glasgow-based 'emerging one-step shop'.Loco Home Retrofit is a retrofit operation that's most interesting for its approach to developing a viable retrofit offer, focused on building trust in communities and with its supply chain as a means to catalysing the decarbonisation of our homes (or at least Glasgow's homes). And now, they're hiring, seeking to fill three positions (below) so if you know of anyone suitable please share the ads:Marketing and community engagement manager Technical manager Innovation programme managerAs much as anything else, we love how they think about the retrofit challenge. Their considered approach to building a proposition and a method is what has really sold us, possibly because it resonates with our UX-focused approach to everything, but mainly because it seems to make sense.Notes from the showThe Loco Home Retrofit websiteChris on LinkedIn Loco Home Retrofit on LinkedInAll three job ads, againChris's interview with BE-ST after winning the Gamechanger award at the Accelerate to Zero Awards 2023Designing an ‘optimal' domestic retrofit programme by Aaron Gillich et al (2017) – The paper Chris couldn't remember the name forLoco Home Retrofit's 2023/24 impact report detailing their innovation efforts to dateResearch Report - The right time for heat pumps in retrofit (Alan Clarke for Passive House Trust) – the other paper that Chris and Jeff reference**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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

The first episode of January 2025 marks the long overdue, first appearance of Jay Stuart, a long-time friend and colleague of Jeff and a firm fixture of the green building scene in Ireland. Jay joined us to talk about his latest project: Loop Your Spare. It's a SaaS platform designed to match 'spare' construction materials with projects that need them on other sites before they have a chance to be classified as waste. It's a concept that could largely eliminate the concept of waste and minimise the need for recycling in construction by enabling materials to remain in their highest-value states, thus retaining their value and mitigating the need to put them through all of the (ultimately destructive) processes involved in recycling. While we're looking to Ireland in this specific case the issues are universal and the solutions should be able to cross borders with relative ease. It's really an episode about smart thinking, with specific reference to a bunch of the projects Jay has worked on in the past and what's coming up in the future.We've wanted to get Jay on for ages because he's an innovative and unconventional thinker who simplifies complex challenges in accessible and unexpected ways. He's also massively experienced, having lectured at University College Dublin's School of Architecture, worked with leading Irish construction businesses like Ecofix and D/RES, and worked as a government advisor to name just a few things.Also, it's an episode that continues the conversations from last year's episodes with Chris Clarke and Don't Waste Buildings and their calls to do something about egregious construction waste in the UK.Notes from the showThe Loop Your Spare website Jay Stuart on LinkedIn Loop Your Spare on LinkedInEmail Loop Your Spare here**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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

What's it like trying to scale a retrofit start-up? This episode welcomes Max Bloomfield and Alex Whitcroft, two of the folks from VundaHaus, to talk about their product, its ongoing design and development, and their preparations to scale the business as they raise funds from investors.VundaHaus designs and manufactures a rapid-fit insulation solution for external wall insulation (EWI) of residential homes. It's a a sophisticated off-site, MMC, insulation jigsaw that's been developed to make the logistics of installation much easier than traditional EWI.There's more to the story but you can listen to that on the episode.Notes from the showThe VundaHaus website The KIN website Max Bloomfield on LinkedIn; email Max hereAlex Whitcroft on LinkedIn; email Alex hereThe TransformER project **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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

This week's episode is all about the lessons learned in carrying out a low-carbon retrofit. Natalie Black (Enbee Architecture + Design) and Toby McLean (Allt Environmental Structural Engineers) joined us to talk through their experiments and experiences on the renovation of a derelict house in Muswell Hill, London that was shortlisted for the Architects Journal Retrofit and Reuse awards this year.This is a project that could easily be misrepresented as a Grand Designs-style endeavour that's only representative of what you can do if you've got loads of capital and capacity, but that wouldn't be fair. This project should really be seen as an example of what you can achieve when you've got loads of capital and the capacity to experiment. The lessons learned here aren't going to solve the housing crisis but they can contribute to resolving the climate crisis, and this is what's motivating our guests. Like many of our listeners, Natalie and Toby are built environment professionals who have become increasingly driven to change how they work by the dawning realisation that the climate crisis is upon us. We also discuss whether you can actually have a low-carbon basement.Links for the PhD applications are below too.Notes from the showNatalie Black on LinkedIn The Muswell Hill low-carbon houseThe Enbee Architecture + Design websiteThe Allt Environmental Structural Engineers' websiteNatalie's LinkedIn post about low-carbon basementsEnbee's 12-minute diary film about the Muswell Hill projectEnbee's short film (under 2 mins) about the Muswell Hill projectNatalie's blog about her workPhD #1 - Balancing Supply and Demand: Developing a Net Zero Energy Framework for Difficult-to-Retrofit Buildings in NottinghamshireNottingham Trent University deadline 8th Dec, start Apr 2025, Led by: Dr Orla Williams (UoN), Co-Supervisors: Dr Kate Simpson (NTU) and Prof Richard Bull (NTU); Community Supervisor(s): Phil Berrill (Nottinghamshire County Council), Chris Beattie (Inspire)PhD #2 - Sustainable Construction UK: Investigating the UK construction industry's culture in relation to meeting long-term social, economic and environmental goalsNottingham Trent University, deadline 14th Feb, start Sep 2025, led by Prof Gavin Killip and Dr Ani RaidenPhD #3 - Re-imagining energy retrofit and home adaptation to deliver safe and resilient homes during interconnected energy, health, housing and climate crisesNottingham Trent University, deadline 14th Feb, start Sep 2025, led by myself with Dr Penelope Siebert and Prof Rowena Hill**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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

Our guest, Liz Male has been on our radar for a while. She is a figure who has been working in the construction sector since the 1990s, an ally to the sustainability sector, a great communicator, and an experienced thinker.When we met earlier in the year we talked about a lot of things, but the consistent theme of our conversation was 'why we need to tell better stories about the built environment'. That said, we kept our powder as dry as we could and moved on to discuss when we might be able to get her onto the podcast to talk about it from the ZAP platform.We get a lot into the chat. Of particular interest is the historical perspective that Liz can offer.

Apologies for the delay, the lost podcast has been returned and is ready for release.'Don't Waste Buildings' should be a straightforward proposition. It seems obvious. Especially so in the face of the climate crisis. Unfortunately, the business of the built environment is not yet on board completely. Our guests for this episode are the founders of UK-based campaign group Don't Waste Buildings, Will Hurst (Architects Journal) Leanne Tritton (Ing Media), and Richard Nelson (Abyss Global).They're a group who are seeking to remedy this challenge by pressuring government and persuading business to both do better. They're doing some really interesting work and they're new, so they need support.Please note: the graphic we refer can be found here (about 15 minutes in).

This week we're speaking with Steven Heath, technical director at Knauf Insulation (UK and Ireland) and a really interesting and experienced person in the sector.So while we had him, we ran through a bunch of our favourite hoary subjects: measuring performance, performance guarantees, and what we think about EPCs.Knauf is a firm that's done some really interesting work in all of these areas and has even managed to make headway with the UK state in getting them to think about the value of testing performance, with EPCs and whatever SHDF is called now (the state-driven money tap for decarbonising social housing).Notes from the showSteven Heath on LinkedInKnauf Insulation's websiteThe ZAP episode with Kate Crawford about HTC and the 'snug factor': A new way to measure performance, negative energy use, and learning from disaster zones, with Kate Crawford (KLH Sustainability)**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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

A wise woman once said: "sustainability is the doing, ESG is the talking about it".Today an Irish house-building giant has made a major move on Passive House — publishing a positioning paper and announcing the ongoing construction of over 1,700 homes to the standard.Joining us to talk about this are Nicola Cronin (Senior Sustainability Analyst) and Stephen O'Shea (Head of Sustainable Construction and ESG Reporting).Rather than this being another episode about Passive House we're more concerned with why a massive housebuilder has chosen to build to the standard. In this case, the answer highlights the positive impact that corporate reporting – in this case ESG – can have on the practice of construction. Where we've often derided ESG factors as a corporate fig leaf, in this instance ESG factors have driven institutional change. Most importantly, the scale of this change clearly illustrates the massive impact that big developers can have.

Jeff invited Mhairi Grant, co founder of award-winning architectural practice Paper Igloo, to join us to talk about the challenges of ensuring that one's ideas for sustainable design actually make their way through to the construction phase.The subject was sparked by a conversation she and Jeff had about lessons learned from a flawed project (that we discuss) and what it takes to ensure that our best, or even just easiest ideas are delivered upon in the build phase. Usually, we'd think about specifying a project in a way that can resist value engineering, but sometimes the project can be scuppered by something as simple as an easily avoidable a comprehension issue.Notes from the showMhairi Grant on LinkedInA link to Scotland's Passivhaus Consultation: Building Regulations: Determining the principles for a Scottish equivalent to the Passivhaus standard: Stage 1 consultationThe Paper Igloo websitePaper Igloo on InstagramThe Passive House Plus feature on Mhairi's own home in Stirlingshire **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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

Why is making UK homes more efficient so difficult? So asked journalist Leyla Boulton earlier this year in the pages of the Financial Times. Seeing a retrofit article in the FT piqued our interest, even more so once we realised Leyla is a senior editor with an esteemed background in political and environmental reporting. She was reporting on Kyoto where no one cared.Since beginning her retrofit journey Leyla has become a campaigner and it's this that you'll hear as we discuss the mainstreaming retrofit for the able-to-pay market, an endeavour borne of her experiences delving into the retrofit sector motivated by efforts to make her own home more energy efficient. Typically we talk about the barriers to take up, a desperately unhelpful planning bureaucracy, poorly designed institutional support, hamstrung local authorities and councils, and the need to do better in designing a system that works.Do check Leyla's article if you can. In spite of the broad air of dismay at how difficult things are, she describes meeting lots of helpful and enthusiastic people who were hamstrung in their efforts.Notes from the showLeyla Boulton on LinkedInFive Lessons from a Neighbourhood Campaign (FT, December 2023) - a free-to-read article in the FT on Leyla's campaign (the others are paywalled)Why is making UK homes more efficient so difficult?

In the UK every day the construction industry produces enough waste to fill a football stadium. Rightly, former guest, Chris Clarke (SCAPE) has got a bee in his bonnet about construction waste and is making efforts to draw attention to the issue. He's not just concerned with the profligate use of resources and the impact on carbon emissions, it's the lackadaisical nature of the waste itself. Waste management accounts for £1.5BN of construction spending every year. In an industry that's operating on margins so tight that any kind of change can be seen to be prohibitively risky, it seems absurd that such a significant amount of waste is priced into every single large-scale project.But, while waste, accounting, reuse, circularity, and MMC are all concepts that have an important part to play, but most important is the front-end work that can be done to reduce waste at the point of design. Whichever way we look at it, when we're asked where we might find the money to drive the circular economy or reduce emissions, it would seem that there might be a simple answer. Even if the solution itself isn't so simple. If we're hoping for infrastructure changes that will make a significant contribution to net-zero efforts and generate revenue, it looks like we might have an easy-ish mark.Notes from the showChris Clarke on LinkedIn (chrisc@scape.co.uk)Construction Waste Portal websiteSCAPE's approach to sustainability  SCAPE - Building for Public Good: A Charter for Change - a policy/lobbying piece produced for the new UK governmentThat Danish development with the recycled brick slips in Architect's JournalWe Build Eco in the pages of Passive House PlusChris's last appearance on Zero AmbitionsInnovate UK's Circular Economy Innovation Network **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, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

This week's guest is Caroline Ashe Brady of KORE Retrofit in Ireland, one of the objectively successful one-stop-shop retrofit providers to have emerged over the past few years.Caroline is a business leader who we're a proper fan of, so apologies in advance for our ‘so Caroline please tell us, why are you so great' style questioning. That said, you can trust us in this opinion, we've done the work with these guys. Caroline was happy to talk about their method, process, challenges and offer up some top tips for how to make it work in the sector, which should be valuable to anyone involved wherever they're based.KORE Retrofit is a business that is ambitious about doing better and has demonstrated that retrofit can be a commercial success. It's not easy, and no-one is perfect, but KORE is operating with a practical plan about how they're going to do better, not just offering up words. Notes from the showCaroline on LinkedInKORE Retrofit's website KORE Insulation's website **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 website)Jeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd'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**

Mainly retrofit though.Informed by Lisa's experiences as a retrofit coordinator, technical lead at RetrofitWorks, and Technical Manager at The Retrofit Academy she knows an awful lot about the challenges faced by retrofit practitioners.

Returning champion Ellora Coupe joins us to talk about the recent report that Her Own Space has published about the place of women in the retrofit sector, which is heartening, insightful, and damning in equal measure. A great piece of work that everyone interested in the sector should heed.Perhaps more importantly, she's with us to promote the incoming launch of its professional sister network Her Retrofit Space, a network for professional women working in the retrofit sector. It's a network that she's created to fill an obvious cultural deficit and in her words "empower professional women to drive retrofit". It sounds brilliant.Finally, a deserving heads-up for Graphenstone as the first signed-up partner for Her Retrofit Space.

This week we're going by Joseph Little, Head of Construction & Building Performance in the School of Architecture, Building and Environment at TU Dublin. He joined us to talk about the journey he's been on leading the MSc in Building Performance over the last seven years, but we got into a lot more. Joseph has been deeply involved in the promotion of better building standards by measuring the performance of buildings for years. Not least with the five Breaking the Mould articles he wrote that Jeff published years ago, sounding the alarm on moisture, condensation, ventilation and a bunch of other issues. We get into all of it and tried to be mindful to keep it to a 'reasonable' length. I'm sure we'll have him back though.Notes from the showJoseph Little on LinkedInBE-ST Fest Summit 2024 - The UK's biggest festival for a zero-carbon built environment, Wednesday 6th November 2024The Built to Last case studies hosted on the Dublin City Council websiteJoseph's papers and articles on the TU Dublin Arrow repositoryThis is A link to the Springboard web page for TU412 Postgrad Certificate in Building Performance open until the end of August 2024, apply during June to get best chance of a subsidised place; oddly, it'll only direct you there if you're in Ireland, so more info can be found here on the TU Dublin websitePartial fill cavity wall: have we reached the limits of the technology?

This week we're thinking about retrofit differently with Dan Hill from Dark Matter Labs (DML). Or rather, we're talking about retrofit's potential to become a movement for social change.In reality, retrofit is about much more than fabric and economics, it's about people and how they live. With that in mind we should be thinking much more about engagement. This is itself a massive challenge because thinking about people properly, as the users of a building, requires a massive shift in how retrofit practice is organised and enacted. Dan has 25 years of experience from working in housing and planning in senior roles at housing associations, Newham Council, CICs, and in a bunch of other consultative roles.We really enjoy talking about these subjects with him because he has gifted us different ways to thinking about the sector, even when we're talking through familiar territory.

This week we're joined by Iva Merheim Eyre from SMARTER4EU to talk about her recently published report the Catalogue of Good Practices, a document that details a variety of place-based hybrid finance models that have been used to rebuild and renovate homes in locations as wide-ranging as the postwar Balkan states to London's own Westminster.This is all part of a concerted effort to use finance to drive better building standards across the world, not just the EU, and there's a lot we can all learn.Notes from the showIva Merheim Eyre on LinkedInThe Smarter Finance 4 EU websiteThe Catalogue of Good Practices a hybrid green finance catalogue for the reconstruction of UkraineLet's build green and elevate A call to action for municipalities to get in touch with SMARTER4EU**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 website)Jeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

Jeff and Dan are joined by Dr. Peter Rickaby again. We were due a catch up so we recorded the conversation because he's always interesting. Peter should need little introduction, so we'll just say he's our favourite retrofit expert (sorry everyone else) and our most frequent guest on the show. He's only returned to the pod, not to the UK. In principle he's migrated to South Africa and is supposed to be retiring, but that's not exactly worked out so far. He has made it to Johannesburg though. Bu, if you haven't encountered him before Peter is one of the heads behind PAS 2035 and Ireland's BER system, amongst many other achievements. Go back and check the earlier episodes too.We had planned to talk about his experiences with the energy situation in South Africa and what we might learn from it but, as ever, we meandered all over the shop covering all sorts: retrofit, natural building materials, heat pumps, fabric first, fabric fifth, novel recycling, embodied carbon etc.Past appearancesRetrofit - Who do you trust?

The other week we had a chance to have a conversation with Cypren Edmunds, President of the European Straw Building Association about building with straw, experiences in retrofit, and the meandering path that led him to the green building trade.For us, it was a really interesting chat because we got to talk about how he got into greed building via sport, the music industry, and playing an active role in his community. The wasn't a built environment professional embarking on a curious diversion in a construction career, it's someone who did something else first and found their way into the building trade later in life, led by interest and making the most of the breadth of their experience. And we got to talk about music for a while, but we cut most of that out because we thought most of our listeners wouldn't be too into it.Notes from the showCypren Edmunds on LinkedInThe European Straw Building Association (ESBA) website The European Straw Building Association (ESBA) on LinkedInThe Association of Straw Bale Building UK (SBUK) websiteThe SBUK Members Directory The SBUK on LinkedInThat 80s Loadsamoney character on TVA map of straw buildings in the UK (database)A straw construction technical guide from The School of Natural BuildingStraw BIM**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

The Recast Energy Performance of Buildings Directive is now enshrined in EU law, which has big implications for the built environment everywhere. Even the South East of England.To mark the occasion and get the lowdown on what this all means, we invited friend of the show Ciarán Cuffe back on to talk about it. For those who might not remember, he's the Irish Green Party MEP and Rapporteur to the EU who has been deeply involved in driving it through.

Kate Crawford is a building nerd who is obsessed with measuring performance. She's currently, Technical Director at KLH Sustainability, a multidisciplinary consultancy working in the built environment. Kate has a very interesting background in terms of her experience and she's now working on a very fascinating project in which she's researching and developing a "Smart Meter Enabled Thermal Energy Rating (SMETER)" system that uses a new approach to measuring building performance and a different kind of metric for assessing it. The result has been something that they call "the snug factor", which is the heat-transfer coefficient of the building (Kate explains it all in the episode). The way they generate their heat-transfer coefficient has led to incredibly accurate estimations for energy use in a home. Notes from the showKate Crawford on LinkedInKLH Sustainability's websiteThe research Jeff mentions about low pressure showers using more waterReal performance and the HEMReal performance and the SAPKate's little (and excellent) graphic novel on her experience of aid work**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

This week we're talking about modular construction and Natural Building Systems with MD Chloe Donovan.Chloe is a really interesting character with a fascinating product that she's bringing to market. Unusually, she's a farmer who got into building and then found herself as an entrepreneur in the febrile world of modular building and MMC.We talk about all sorts, from the challenges of propagating a biogenic supply chain to the ever-contentious subject of calculating embodied carbon, and a little about what's going on in MMC.Notes from the showChloe Donovan on LinkedInNatural Building Systems websiteNatural Building Systems on LinkedIn**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 our day jobs.Follow us on the Zero Ambitions LinkedIn pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

Up next we're speaking with Falk Bleyl, CTO at Utopi, about their sensor-based data platform technology. He describes it as an ESG platform which is true but it massively underplays the true value of what their product offers. Heads up, normally, we'll at least try to couch the conversation within a broader context but in this episode, we've barely bothered. We were content just to talk about the product, how it's deployed, and its impact precisely because the value it offers addresses things we talk about nearly every week.So we could be accused of having created an advertorial, but we don't care because it's not.  In the most reductive sense, Utopi offers a glorified post-occupancy evaluation (POE) platform. They install sensors, monitor them, manage and interpret the data, and advise their clients on how to respond to what they learn.It is a service that is as relevant to the most red-in-tooth-and-claw capitalist landlord as it is an aspirant socialist housing provider.Utopi uses sophisticated monitoring and maintenance strategies to prove a direct cause-and-effect on the value of the building assets. This is massively important for a world where the public sector is instructed to copy the private sector and indulge political desires for market-based decision-making, whether it's more efficient in reality or not. Utopi's platform proves that efficiency pays, POE pays, and (tangentially) retrofit pays.

Lloyd has been in Paris. He came back very enthused and excited by his experience there and wanted to communicate why to our listeners.“In the face of the climate emergency, a swift transition of the buildings sector is a direct requirement to achieve the goals set by the Paris Agreement”.Approximately, 1,400 people from 70 countries gathered in Paris for the Buildings and Climate Global Forum and the Declaration de Chaillot was the resultLloyd Alter, Will Arnold, and Kelly Alvarez Doran were there. The question is, what does this declaration mean? Will it actually have a real impact on the way we build, or is it just another bit of paper that will be quickly forgotten? This feels like a very positive sign because it's pulling together the usually loose strands of how we appreciate the built environment and what needs to be done to make it work better for everyone in it, as well as the environment around us.Notes from the showLloyd Alter on LinkedInKelly Alvarez Doran on LinkedInWill Arnold on LinkedInThe UNEP page on the Declaration de ChaillotThe Institution of Structural Engineers web pageThe Buildings and Climate Global Forum web page**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

This week we got into an area of retrofit that feels neglected: commercial space. It's a subject we definitely touch upon but never really get into , so in order to remedy that we're getting stuck in.First up is a conversation with architects Harry Browne and Séamus Guidera of RKD Dublin who came recommended to us by friend of the show Richard O'Hegarty.In a sector less driven by traditional sustainability issues, and more driven by hardcore commercial issues, it seemed right to start by speaking with folk who know their stuff. Harry and Séamus have been grappling with the big commercial questions around place of the office in the future and the renewal of these built environment assets, offering commercial clients the sort of strategic that hasn't been necessary in this sector for decades. Nowadays, asset owners are thinking about impact, in terms of how the building asset's use influences and interacts with its surroundings, how they can make offices more attractive places to be, not just providing serviceable desks. This evolving approach encourages engagement with tenants to plan for the future, incorporating changing use alongside changing climate, and how to make the renewal and retrofit process more efficient in terms of resource use and minimising waste.There's loads to get into. Too much. but this is a start.Notes from the showHarry Browne on LinkedInSéamus Guidera on LinkedInThe RKD website**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

We are delighted to bring you a conversation with Professor Emeritus Susan Roaf, of Heriot-Watt University this week to talk about a bunch of fundamental problems in building design and the management of thermal comfort. She is a wonderful guest and we're looking forward to having her back.Originally, we planned to talk about her article COP 28: Net zero buildings by 2050? You have got to be joking! a well-judged critique of the outcomes at the most recent COP but we meandered a bit more than expected, but we still managed to cover most of the issues she raises.In the end, we took in a shared colonial history and its influence on the way we approach managing thermal comfort, problems with architectural education, the flaws in solely thinking about decarbonisation of the grid as a panacea, problems with designing buildings have an over-reliance on technology, as well as her colourful and storied background. In some ways with could be considered a counterpart to last year's episode about thermal comfort with Huda Elsherfif and Andy Simmonds, so check that too if you haven't heard it already.Notes from the showSusan on LinkedInHer article COP 28: Net zero buildings by 2050?

This week we're joined by Nigel Banks, Technical Director - Zero Bills & Low Carbon Homes at Octopus Energy.Nigel joined us to discuss his recent article: Fabric Fifth, a slightly polemical riposte to fabric-first dogma, and an interesting philosophy for retrofit. As it turned out, it's an apposite follow-up to last week's episode with Fionn Stevenson.Fabric Fifth - Nigel BanksASHPs ASAPGet SmartMeasure & get comfySolar & StorageFabric FifthWe also touch on Octopus's zero-bills proposition, but we'll do a full episode about that soon.Notes from the showNigel on LinkedInThe Fabric Fifth article itselfAn article about Chris Warboys' SAP conversion toolThe academic paper Jeff mentions: UK Passivhaus and the energy performance gapNigel in the pages of Passive House Plus**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

We were blessed to enjoy a great conversation about retrofit and what we should consider our priorities, with the vastly experienced retrofit firebrand Fionn Stevenson.It was a challenging, surprising, and free-wheeling conversation spurred by a call to action she made on LinkedIn some time ago, in which she decried fabric-first approaches and declared: "We need to tackle low hanging fruit first".That post we're referring to:"This is why " fabric first" as a blanket approach to retrofit is not always the best solution. Some properties will do better with cheaper renewable energy heating options without the expensive faff of additional external wall insulation, lack of construction skills and building physics understanding - which is massive in the industry. Just massive. We need to tackle low-hanging fruit first."Now, we don't expect you to agree with everything she has to say, but you're only doing yourself a disservice if you don't listen.Notes from the showFionn on LinkedInThe Know Your Home logbook for homes platform, and its Seedrs capital raising page**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

We enjoyed the company of Ecomerchant's Will Kirkman a business that's specialised in sustainable and natural building materials for the building trade and consumers.We mainly rambled our way around the culture of building in the UK, how embodied carbon has always been on the Ecomerchant agenda and the impact that sustainable and natural building materials have on the buildings they make and the people who occupy them.Notes from the showWill on LinkedInThe Ecomerchant websiteThe We Build Eco websiteStewart Lee's taxi driver argumentUBS white paper: Rethink, rebuild, reimagine (on laying the foundation for better buildings)UBS  report: Retrofit revolutionUBS report: Under one roof (opportunities for public and private stakeholders to decarbonize the global building sector)UBS report: Building society (looking at the social opportunity of retrofitting and the relationship between retrofitting and area regeneration)**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

This week is all about the challenges of low-impact building in the sphere of self build with Tara Fraser, a chartered civil and structural engineer, and a director of Build Collective in Bristol. On the recommendation of former guest (and Tara's colleague) Beth Williams, we recently had a chat with her about a self-build project she worked on that should find itself into the pages of Passive House Plus magazine, and we thought it'd be interesting to explore it, and a few broader themes, for the podcast too.This is because in green building it's the self-builders who have been the pioneers, which intrigued us to wonder what lessons might be taken from the self-build experience that can be used by other builders.It's pretty nerdy this one, but don't worry if you get lost on some of the detail, that's fine, it'll pass, and we return to the common ZAP themes pretty quickly.Notes from the showTara on LinkedInThe Build Collective websiteTara's colleague, Beth Williams, on the podcast last year**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

Part two of our series on shading, this time with a return appearance from Tom Dollard of Pollard Thomas Edwards who joined us in January 2023 to talk about lazy thinking. Ostensibly, this time we met to talk about the Good Homes Alliance design guide for shading, as a follow-up to December's episode with Zoe De Grussa.  On reflection we realised that the guide does a good enough job without us disecting it, so we spent more time discussing why such a guide is necessary, how the industry needs to change, and why it's struggling to do so (culture, economics, and politics…the usual).Content warning: it is a very rambling episode but in spite of its very loose sense of direction the conversation does cover a lot.  The warning is just because we only really talk about shading 20 minutes in, so heads-up if you read this before you start listening.Also, it's a very UK-heavy discussion because those were the conditions in which the research was created, but they're pretty-much analogous for a great deal of Ireland, North America, and probably great swathes of Europe too. Please check the link below, download the PDF, read it, and share it - it's a brilliant piece of work.Notes from the showTom on LinkedInThe Pollard Thomas Edwards websiteShading for housing: Design guide for a changing climate, published by the Good Homes Alliance in collaboration with the BBSA**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

With us this week is new friend, Kelly Alvarez Doran, via an introduction from Lloyd to talk about his experiences at COP28 and his carbon reduction consultancy Ha/f Climate Design that's challenged itself to reduce Canadian construction's emissions by half.We get sidetracked almost immediately while we talk about Kelly's background as an architect, working in mining, and the big changes to philosophy on building after working in Rwanda. In spite of the early diversion, we spent the whole conversation consistently hitting the same key themes themes:Embodied carbon and life cycle analysis Designing for the end of Oil-Age architectureRethinking the role of building design in the age of embodied carbon Kelly's great. He'll be back. Hopefully without any sound issues next time (it gets better after a bit).Also, XPS = Extruded polystyrene insulation.Notes from the showKelly on LinkedinConversations on the phasing out of oil felt paradoxical amidst the Dubai backdrop (The Architect's Newspaper, January 2024), Kelly's original view from COP28Embodied Embodied carbon values of common insulation materials (Canadian Architect, April 2021) i.e. the article with the chart that names brand names alongside embodied carbon values and egregious payback lead times for common insulation materialsThe YouTube video of the Straw Panel vs. Conventional Construction Burn Test that Kelly refers toThe Ha/f Climate Design websiteBuilding LCA for Architects Online Course (OneClick) a free primer course for architects by KellyThe UK Government Flood Risk Tool **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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

This one is about conservation-led retrofit and the retrofit of commercial (or institutional) building stock. We were invited to see a recent Iarnród Éireann (Irish Railway) retrofit project and meet with Heidi Hopper-Duffy (Environmental & Sustainability Manager) and its architect David Hughes (Senior Conservation Architect & Energy Specialist).Ostensibly, we're talking about energy efficiency and conservation of built heritage. The project was led by David, a retrofit of a historic building shared between Iarnród Éireann and the Chief Medical Officer's (CMO) office. We talk about it but you'll get to see the works in much more detail when Jeff features it in the pages of Passive House Plus. In this case, the railway, guided by David and Heidi's experience, can be lauded as a leader in its field and these sorts of projects are illustrative of the challenges and opportunities that come with working in a large company or institution.We also cover broader bits: design for deconstruction, BERs, what should we be quantifying i.e. carbon or energy, or what?Mind the background noise - we had a few unexpected background interruptions from an occasionally boisterous meeting room next door.

The first of our Dublin field recordings is with Archie O'Donnell a long-time face green building in Ireland, a fella who Jeff has a lot of time for, and someone Alex and I hadn't met yet. It was a good call. Originally trained as an architect, Archie has worked his way through the industry, recently joining Danish/Irish consultancy KOSMOS, so there was plenty of scope for the conversation to meander from observations on how the green building industry has changed and is changing, to costing sustainability, accounting for language, the impact of the EU taxonomy and imminent evolutions in energy rating.Interestingly, we didn't recognise the significance of Jeff's Calvinball analogy though, so listen out for that. In Calvinball nature of the game was to make the rules up as you go along, so you're never really held accountable, you can't lose, and the game you're playing can't be brought to an end. This definitely echoes the nature of our fossil fuel, ESG, and sustainability accounting systems. Notes from the showArchie on LinkedInThe KOSMOS websiteCalvinball - check it, Jeff may have stumbled onto something there**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

This week we have Lloyd's latest Passive House Plus Revisited, a conversation with passive house heads Alan Clarke and Nick Grant about the passive house archive project that left Lloyd so smitten when he visited it last summer.That we're discussing archive systems shouldn't put folk off - the point is about thinking differently, about what the challenge really is, recognising the reality of systems, the elevation of simplicity, and reclaiming the phrase “value engineering”.Notes from the showFollow Nick Grant on Twitter and Bluesky Follow Alan Clarke on Twitter and BlueskyThe Passive House Plus article that inspired the episode: Hereford archive chooses passive preservation, by Kate de SelincourtElemental Solutions, their practiceThe Conservation Physics website that we mention**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

Happy new year! This week's episode brings you a conversation with Ethan Wadsworth of DiscreteHeat the manufacturers of our new favourite energy efficient (non-radiator and non underfloor) based heating system ThermaSkirt. We're not there to bang on about a product we like, what we found interesting about this one is that it's an overnight, award-winning success that took fifteen years to bring to fruition. This means that our conversation is mainly about what's changed in the heating and building space to enable the growing demand for ThermaSkirt, and what that can tell us about the broader market for products related to sustainability and decarbonisation. Ethan had a lot to say about why the product is relevant now, not just what it does and how it works.There's a lot that folk in the decarbonisation sector could learn from these guys because they've really considered the customer experience of both the end consumer, the distributor, and the installer. This is proper business strategy using analysis of all user journeys and experiences, so we love it. We also talk about heating design for a bit too.Notes from the showThe ThermaSkirt websiteEthan Wadsworth on LinkedInThermodul vs Thermaskirt® – Skirting Heating Systems Compared, the Thermodul-produced article we start talking aboutThe ThermaSkirt YouTube channelThermaSkirt on Instagram**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 pageJeff, Alex, and Dan about websites, branding, and communications - zap@eiux.agency; Everything is User ExperienceSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Own Space, the renovation and retrofit platform for women (but not in a patronizing way)**END OF SELF-PROMOTING CALLS TO ACTION**

Happy post-Christmas day, hope you made it through OK. Today we have part two of the latest Passive House Plus revisited, looking at Lloyd Alter's favourite article of 2021: Seeing the wood for the trees - Placing ecology at the heart of construction.Again, we're joined by authors Lenny Antonelli and Andy Simmonds talking about mass timber, embodied carbon, why we should just use less and, unexpectedly, the place of AI.It turned out to be an extra long one but it felt deserving of the space, so rather than butcher the conversation we thought we'd just cut it in two and let you hear the lot.

Merry Christmas!This week we have a Passive House Plus revisited two-parter for you, led by our occasional co-host Lloyd Alter, looking at his favourite article of 2021: Seeing the wood for the trees - Placing ecology at the heart of construction.We're joined by authors Lenny Antonelli and Andy Simmonds and the conversation wheels around, covering the place of mass timber as a solution to construction's problems, embodied carbon, why we should just use less, and why it's so hard to use less, amongst lots of other things.It turned out to be an extra long one but it felt deserving of the space, so rather than butcher the conversation we thought we'd just cut it in two and let you hear the lot.

It's all about shading, overheating, and solar gain with Zoe De Grussa this week. She's the author of that infamous Camden overheating case study that Jeff always references and, at the time of writing, is technical and sustainability consultant at the British Blind and Shutter Association (BBSA).We cover Camden, but perhaps more interesting is the conversation around the difficulties in modeling shading, and the consequent difficulty in communicating its value to a project. Despite shading measures being 3-4 times cheaper to install at the point of a building's origination, rather than retrofitting it when there's a problem, it's all too often one of the first things value-engineered out of the specification.Notes from the showZoe on LinkedInThe BBSA websiteThe Home Energy Modeling ConsultationZoe's infamous academic paper: Overheating Camden Case Study.
