    Fundamental problems in building design and how we manage thermal comfort, with Susan Roaf (Heriot-Watt; ICARB)

    Fundamental problems in building design and how we manage thermal comfort, with Susan Roaf (Heriot-Watt; ICARB)

    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.

    Fabric fifth: rethinking the hierarchy of retrofit, with Nigel Banks (Octopus Energy)

    Fabric fifth: rethinking the hierarchy of retrofit, with Nigel Banks (Octopus Energy)

    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.

    Retrofit: "We need to tackle low hanging fruit first", so what does that mean? With Fionn Stevenson

    Retrofit: "We need to tackle low hanging fruit first", so what does that mean? With Fionn Stevenson

    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.

    Natural materials, healthier homes, and the culture of sustainable building, with Will Kirkman (Ecomerchant)

    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.

    Engineering low-impact buildings and advice from self build, with Tara Fraser (Build Collective)

    Engineering low-impact buildings and advice from self build, with Tara Fraser (Build Collective)

    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.

    Shady business #2: shading for housing in a changing climate, with Tom Dollard (Pollard Thomas Edwards)

    Shady business #2: shading for housing in a changing climate, with Tom Dollard (Pollard Thomas Edwards)

    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.

    A view from COP28, and relearning how to be an architect for after the Oil Age, with Kelly Alvarez Doran (Half Climate Design; Architecture 2030 Senior Fellow)

    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 architecture
    • Rethinking 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.

    Conservation-led retrofit and energy efficiency for working buildings, with with Heidi Hopper-Duffy and David Hughes (Iarnród Éireann)

    Conservation-led retrofit and energy efficiency for working buildings, with with Heidi Hopper-Duffy and David Hughes (Iarnród Éireann)

    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 cost of sustainability, accounting for language, and the taxonomy, with Archie O'Donnell (KOSMOS)

    The cost of sustainability, accounting for language, and the taxonomy, with Archie O'Donnell (KOSMOS)

    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.

    PH+ Revisited: that archive building in Hereford, the one that uses passive house preservation, with Nick Grant and Alan Clarke

    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”.

    How to normalise low-energy heating without radiators: an overnight success story that's fifteen years in the making, with Ethan Wadsworth (ThermaSkirt)

    How to normalise low-energy heating without radiators: an overnight success story that's fifteen years in the making, with Ethan Wadsworth (ThermaSkirt)

    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.

    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. Hope you enjoy it as much as we did.

    Shady business #1 – overheating, and Camden: we should think about solar gain all year round, with Zoe De Grussa (BBSA)

    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.

    POE and its value to retrofit, and what does a Head of Sustainability do? With Loreana Padron (ECD Architects)

    POE and its value to retrofit, and what does a Head of Sustainability do? With Loreana Padron (ECD Architects)

    We are joined by Loreana Padron to talk about what it is that a Head of Sustainability does and, more broadly, the value of post-occupancy evaluation (POE) to all the stakeholders in a retrofit project.

    Loreana tells us about the path she's taken to becoming Head of Sustainability at Architecture firm ECD, a leading sustainability-focused practice, and we take some time to revisit the Wilmcote House project which we featured way back in 2021.

    This time, we're more focused on the POE aspect, in part, driven by the inclusion of the Wilmcote House project in Marion Baeli's 10 retrofits revisited project which we featured back in April.

    Some listeners may want to go back to episode, 23 EnerPHit at Scale with James Traynor of ECD Architects. It's a very old one, so please bear in mind that as badly produced as this podcast may be now (still) we've got a lot better. The content is excellent still though because James is brilliant and it's an amazing project.

    Listen out for news about the retrofit design course she's been editing and the 'secret' group of heads of sustainability, something that should be a much more common model for sharing knowledge, providing an opportunity for bigger practices who can invest in research to share it with smaller practices to further the cause.

    Sustainability and the Next Generation of Designers | IIDA at NeoCon

    Sustainability and the Next Generation of Designers | IIDA at NeoCon

    Earlier this year at NeoCon 2023—OFS, Imagine a Place, and IIDA hosted a lively roundtable discussion focused on sustainability, moderated by sustainability leader George Bandy. The panel featured Stacey Crumbaker, an architect and designer based in Seattle, and Paul Shahriari, founder of green building data platform ecomedes. Their conversation offered wisdom and advice for the next generation of interior designers and architects aiming to make sustainability a priority in their work.

    How does the next generation get involved and make changes? Building and developing a personal brand that puts you in the position to advocate for sustainable design in your current position is a great way to get involved. Make the case for conscious material choices and their impacts. Legacy mindsets are part of the problem, but designers can create a new legacy mindset—one that aims to reduce consumption and waste, not just meeting minimum requirements. Consider the full lifecycle of your specifications and be mindful of the generational impact.

    Designers need to redefine beauty and realign the definition with sustainability. Seek out inspiration from a diversity of spaces like food deserts (geographic areas, often low-income neighborhoods, where residents have limited access to affordable, nutritious food), not just affluent communities. We need to design with marginalized users in mind and include them in the process.

    Standards and specifications, and why they don't always work like we want them to, with Sarah Price, the author of PAS2035/2030 (Retrofitting dwellings for improved energy efficiency)

    Standards and specifications, and why they don't always work like we want them to, with Sarah Price, the author of PAS2035/2030 (Retrofitting dwellings for improved energy efficiency)

    Today we're talking about standards. In short, it's about how standards are written and why retrofit shouldn’t just be about products or carbon. It's never short with us though, is it?

    We're sure that all of our listeners will have complained about PAS2035/2030 at some point, admiring its ambition while lamenting its restrictions. We've all certainly wondered how they come to be like that too.

    So, we thought we'd have a go at humanising the UK's most prominent retrofit specification and guidance, by introducing our listeners to its author, Sarah Price. We meander our way around PAS, CarbonLite, Passive House Plus, the great Preston retrofit catastrophe, and even get onto the cases for, and against, spray foam insulation.

    Roadmaps for fuel poverty and retrofit: we know what needs to be done so why can’t we do it? With Tania Jennings (Chair of the Association of Local Energy Officers, London)

    Roadmaps for fuel poverty and retrofit: we know what needs to be done so why can’t we do it? With Tania Jennings (Chair of the Association of Local Energy Officers, London)

    We invited Tania Jennings back. Most folk in the retrofit or social housing space will probably be aware of Tania from LinkedIn and the myriad jobs she has.

    If you don’t know her yet, check her LinkedIn.

    Anyway, she wrote a thing for Architect’s Journal about fuel poverty, Covid, and inevitably retrofit and it was excellent. 

    It sparked a conversation about why we’re barely making a dent in resolving the massive pile of retrofit problems in front of us, one that seemed ripe for the podcast, so we brought Jeff and Alex into it too.

    Broadly, we need better roadmaps and collaboration to enable the change we want to see. We know that the solutions are, it's just that we're not able to deploy them if we carry on going about things the way we currently are.

    Driving change in building design and the things that inspire you to do better, with Cedric Burgers (Burgers Architecture)

    If you fancy, you can settle in for a long one this week, in which Jeff and Dan speak with award-winning Canadian architect and passive house designer Cedric Burgers.

    We cover all sorts because he has led a pretty interesting life and he has a lot to say about sustainable building design, particularly his love for passive house as a philosophy, the drivers of change in favour of sustainable design, and the experiences and people that have influenced him.

    Biogenic building, whole life carbon, and natural fibre insulation. With Sam Baumber (IndiNature)

    This week we're talking about natural fibre insulation and the potential of biogenic building products with IndiNature manufacturer (and co-founder) Sam Baumber. 

    It feels like a timely follow-up to last week's episode about quantifying embodied carbon, particularly in relation to the role biogenic products have in providing a mid-to-long-term carbon buffer. But we get into the other aspects of interest, addressing fire safety, health, thermal performance, and economic benefits.

    It wasn't intended to sound like an advertorial but, listening back it does a little. This is because it's a product that we're enthusiastic about. We hope that you are too.
