    When perseverance pays off: A rural barn conversion

    When perseverance pays off: A rural barn conversion

    In this inspiring episode, we delve into the remarkable self-build journey of Ade, an architectural designer and project manager, who transformed a dilapidated barn into a dream home for his family in the picturesque Kent countryside. 

    We discuss his drive to uncover hidden opportunities, his commitment to maintaining the highest standards throughout the conversion process, and the challenges of putting the fate of your future in the hands of the planners.

    Construction's embodied carbon problem: how do we incentivise retrofit over 'demolish and rebuild', with Joseph Kilroy (CIOB)

    Construction's embodied carbon problem: how do we incentivise retrofit over 'demolish and rebuild', with Joseph Kilroy (CIOB)

    Jeff received a press release that piqued his interest, so we invited the man behind the call to action, Joseph Kilroy, (Head of Policy and Public Affairs at the Chartered Institute of Building (CIOB)).

    Joseph joins us to talk about their ideas for increasing the pace of change required to meet the ubiquitous net zero 2050 targets. They're calling for government to incentivise better building practices by using the tax system to create an economic environment that supports the spirit of climate legislation rather than undermining it.

    Specifically, we talk about the impact that charging the full rate of VAT for demolition in Ireland would have if a reduced rate for repair and refurbishment was maintained, and the idea of introducing a levy for demolition as a similar catalyst. But these same ideas could probably be applied much the same anywhere.

    Getting real about energy research and making heat pumps chic, with Mike Fell (UCL; pump:chic)

    Getting real about energy research and making heat pumps chic, with Mike Fell (UCL; pump:chic)

    This week we're joined by Mike Fell, energy researcher at UCL, amongst many other things.

    We've been following Mike's work for a while, (mainly because the pump:chic work is really interesting to us) and when we clocked he's co-authored this paper about realist approaches in energy research we saw an opportunity to bring him onto the podcast.

    Realist approaches ask not just ‘what works?’, but ‘for whom does it work, under what circumstances, and why?', all good subjects for enquiry in any project.

    It's much less academic than it might sound. We think it's a really valuable way of approaching research so we wanted to talk with Mike about how he's been using the approach and give us a chance to promote it all to our listeners.

    We also want folk to check out all the other interesting things he's up to as well. Check the links below.

    Stranded assets, financing sustainability, and carbon as a risk factor, with Alexandra Hedesiu (EnerSave Capital)

    Stranded assets, financing sustainability, and carbon as a risk factor, with Alexandra Hedesiu (EnerSave Capital)

    This week Jeff introduced us to a new friend he met while working on a EU funded green finance project, Alexandra Hedesiu, Head of ESG & EU Advisory Services at EnerSave Capital.

    The EU Life-funded project is called Smarter Finance for EU, and its aim is to develop the market for credible green home certifications and associated green mortgage, loan and development finance products, with €8.5bn worth of projects already built or planned under a previous phase of the Smarter initiative.

    As well as getting into the drivers of how large sustainability projects get financed, Alex was able to highlight how the demands of finance are changing the construction industry for the better and how sustainability is being recognised as a risk factor by money men.

    It's pretty clear that finance is going to demand more accountability from the construction industry, in terms of sustainability strategy and reporting, and that some developers are already feeling the pain of stranded assets. This is all before we touched on carbon pricing.

    It seems clear that all businesses that work within the built environment should think about how they're going to step up in their own accounting and reporting, because pretty soon every entity in the supply chain will be having questions asked of it.

    Thermal comfort in building design: thinking ahead and taking lessons from East Africa, with Huda Elsherif (calfordsedan) and Andy Simmonds (AECB)

    Thermal comfort in building design: thinking ahead and taking lessons from East Africa, with Huda Elsherif (calfordsedan) and Andy Simmonds (AECB)

    In the midst of a weirdly warm October for this part of the work, we're talking about thermal comfort in building design with Huda Elsherif and Andy Simmonds about a project they've been collaborating on in Tanzania.

    While the lessons we can learn from it might not be immediately obvious, there are plenty of them there to be had as our climate grows warmer. In terms of building design it's already clear that we should be thinking ahead, planning for today's needs and building with one eye on future adaptation.

    Air conditioning is an incredibly convenient solution in the global north, but it's very fragile, and a reliance on it does not lead to an adequate supply of resilient building stock if we're designing for a climate with higher temperatures. The overuse of air condition has appalling implications when we consider its inefficient use of energy, implicit challenges in generating enough energy to meet demand (already a problem in California), and big problems down the line when buildings designed for air conditioning can't use it.

    We also get to touch on cultural difference in building design and the impact that can have, wherever we are, the inadequacy of the assumptions made in standardised guidelines (i.e. the deficiencies in SAP or DEAP), and a few mosquito facts.

    A schism in building standards: promoting passive house and high performance building in the USA, with Zack Semke (Passive House Accelerator)

    A schism in building standards: promoting passive house and high performance building in the USA, with Zack Semke (Passive House Accelerator)

    Lloyd Alter introduced us to Passive House Accelerator earlier this year and it turns out that we're doing some quite similar work, promoting high-performance building, sharing innovation, and elevating thought leadership.

    Instead of starting a blood feud, we decided to invite Zack Semke onto the podcast to talk about what they're up to and see what we can learn from them. As it turns out, they're doing some really interesting stuff and Zack had already interviewed Jeff ages ago. Seems like we should look into collaborating.

    We had a chat about their stateside perspective on high-performance building, how to make sense of the place of passive house globally, and the schism between PHI vs PHIUS standards(European vs US).

    It went into a bunch of other things too. All fairly familiar subject matter, substantially less Brexit than usual but more naked culture war nonsense. Whatever we think about the nuance of the standards, it's clear that US adoption of passive house has massive potential to push things forward.

    Building a place for women in retrofit, with Ellora Coupe (Her Own Space)

    Building a place for women in retrofit, with Ellora Coupe (Her Own Space)

    We've a slightly different episode for you this week. Our guest is Ellora Coupe who we think has a big part to play in the retrofit space without performing one of its traditional roles.

    Ellora is the founder of Her Own Space, a platform that provides a women-only space to share knowledge, insight, support, and help in all things to do with renovation.

    It's an incredibly engaged community that has an awful lot to offer the whole industry if we're open to paying attention and offering some support. We're very enthused.

    Also, you can donate money to Her Own Space here.

    The benefits of energy efficient building are much more than energy efficiency, with Marion Jammet (Irish Green Building Council)

    The benefits of energy efficient building are much more than energy efficiency, with Marion Jammet (Irish Green Building Council)

    It was about time we had someone from the Irish Green Building Council (IGBC) join us on the podcast. So Jeff invited Marion Jammet, the IGBC's Head of Policy and Advocacy, to join us to talk though a recent white paper they published in conjunction with the Institute of International and European Affairs.

    The paper is titled: Reviewing the Co-benefits of Energy Efficiency in an Irish context and it's well worth a look for all of our listeners. While its focus is on the situation in Ireland specifically, it's relevant to all of us. The themes, problems, and solutions discussed in the document are broadly the same wherever you are, even if the details and the politics differ.

    You can find the paper here.

    Retail perspectives on retrofit and high performance building, with Andy Mitchell (Green Building Store)

    Retail perspectives on retrofit and high performance building, with Andy Mitchell (Green Building Store)

    We often talk about the notion of selling high performance building to people but we rarely seem to talk with people who actually deal with the customers.

    In an effort to fill this gap we were joined by Andy Mitchell, MD at Green Building Store, a long-established retailer of all the things a high-performance building might require, and a passive house specialist.

    We start with ventilation before meandering our way through customer needs, the value of design, passive house, window sills, retrofit, and all the sort of things you might expect from us by now.

    Get your heat from the streets: Kensa Utilities' plans for geothermal district heating, with Lisa Tresedar (Kensa Utilities)

    More heat-related chat this week.

    We're with Lisa Tresedar of Kensa Utilities joined us. She’s the string-puller behind Kensa’s Heat the Streets project the success of which has garnered national coverage because of its innovation and its success so far (which is now up for an award).

    Heat the Streets is a pioneering project in which Kensa sought to provide a Cornish village, that wasn’t on the gas grid, with its own grid infrastructure using a geothermal heat network and heat pumps.

    So, we talked about how the project got started, the challenges of decarbonisation, what they learned about user behaviour, where they see opportunity in the space, what's motivating Kensa, and what they plan to do next

    There are loads in there for anyone who's thinking about heating decarbonisation and community-based solutions. What's particularly heartening is that this has worked here and shows plenty of potential to work elsewhere too.

    Scaling high performance buildings AKA EnerPHit is no more expensive than retrofit, with Mel Reynolds

    Scaling high performance buildings AKA EnerPHit is no more expensive than retrofit, with Mel Reynolds

    'EnerPHit need not be any more expensive than retrofit': those are the words that we put into the mouth of this week's guest Mel Reynolds. He stood by them, even if they weren't his own, but advisedly. It's not necessarily easy, but it can be done, and it can be scaled up.

    Mel took us through his experience in working on high-performance buildings, learning passive house principles, undertaking his own new builds, and applying everything he's learned to carry out EnerPHit-standard retrofit. The standards and good practices that he's learned have been incorporated as common sense standards to uphold whatever project he's working on, and he's made it work.

    The long and short of the conversation is that good planning and design will improve your impact (comfort and carbon) without necessarily increasing construction costs.

    PH+ revisited: Let's get decarbonisation done, with Toby Cambray (UCL, Greengauge Building Energy Consultants)

    PH+ revisited: Let's get decarbonisation done, with Toby Cambray (UCL, Greengauge Building Energy Consultants)

    Lauding an alternative viewpoint to always aiming for the loftiest standards, in this PH+ Revisited Lloyd is championing Toby Cambray's Insulate Britain-inspired article, from February 2022: Let's get decarbonisation done.

    It's an article about taking a differently-considered approach to domestic decarbonisation strategy and one that Lloyd has referenced frequently because of its refreshingly pragmatic look at prioritising our action. Should we favour deep, whole-house retrofits as per traditional Passivhaus dogma, or should we push for the installation of heat pumps and do just enough retrofit to make it all work?

    You can read what Lloyd has written about 'heatpumpification' in response to Toby's article on Treehugger but this feels like sufficient summary for here:

    "He breaks my spellchecker by verbing heat pumps, writing that while you could just install heat pumps, "this does not however mean that it’s a good idea to put a heat pump in a building with poor fabric efficiency. Although there are cases where other constraints mean we have little choice, ultimately we need to both (mostly) Insulate Britain and (mostly) Heatpumpify Britain." Heatpumpify and heatpumpification have been added to my dictionary".

    Retrofit is a part of the climate discourse that can often feel dominated by a puritan attitude towards fabric-first approaches and the heresy that Toby presents feels like a  practical philosophy that balances high-performance building with an awareness of embodied carbon.

    We also make sure that Richard Lowes gets his credit for authoring this new verb: to "heatpumpify" a home or building.

    And, when we get around to learning iMovie, there might be a little bit of video on our Zero Ambitions LinkedIn page, so give us a follow there if you can.

    Finance is the easy part: place-based innovation can catalyse mass-scale retrofit, with Rufus Grantham (Living Places)

    Joined by returning champion, Rufus Grantham, we're talking about using community and place-based approaches to catalysing large-scale retrofit. To this end he's set up a new consultancy Living Places and he'll tell you all about it this week.

    We're not pretending it's actually easy, but if you create the opportunity the finance will follow, and setting up the opportunity is a lot harder than finding money that wants to be put to 'work'.

    We cover everything we can in the time we have: net zero neighbourhoods, innovative finance in lieu of debt, social benefit opportunities, supply chains, and touch on the limited (or limiting) role of green mortgages.

    We're really looking forward to seeing what happens with this one.

    Regional energy, local heat, and mass decarbonisation: a new model on the River Clyde, with Duncan Smith and Richard Orr (River Clyde Homes)

    Welcome home Duncan Smith! And, we're pleased to introduce Richard Orr, Head of Asset and Regeneration at River Clyde Homes.

    We've been alluding to the things that Duncan is up in his new role as Head of Energy & Sustainability, so we were delighted when he said he'd come back to tell us all about his new life in Greenock.

    The work they're doing should be as significant for private developers as it is for the social housing sector. It's a big strategic project, providing better homes for their tenants, and better living for a whole community on the River Clyde.

    They're being very ambitious and they're well aware that they won't meet all of their lofty aspirations, but what they're achieving already feels pretty significant. Approaching asset development and renewal with a long-term vision that is addressing: fuel poverty, demand reduction, localised energy generation and distribution, community wealth building, and even a carbon offsetting scheme that could really make a difference.

    Fabric second, not fabric first: impact, heritage, retrofit, and strategy, with Kit Knowles (Ecospheric)

    Fabric second, not fabric first: impact, heritage, retrofit, and strategy, with Kit Knowles (Ecospheric)

    Kit Knowles is a sustainability consultant whose pioneering practice, Ecospheric, is forging its own path, concerned with making the greatest impact, getting things done, and big backer of research so they can learn how to do better.


    This week’s episode can be summarised as being about “the inherent conservation of energy principles associated with a building” i.e. design before fabric, and doing the work on paper before you get close to construction. Hence, ‘fabric second, not fabric first’.


    His firm, Ecospheric, is an award-winning consultancy that supports planners, architects, and developers in designing and delivering pioneering eco developments that save carbon and drive technological change. There’s every chance that you’ll have encountered his work before, particularly the renowned Zetland Passive House in Manchester.


    We touch on a bit of everything but there’s loads more to see to check the Ecospheric website.

    PH+ revisited: 'Cold Truths' about heating and energy in Britain, with Kate de Selincourt

    Today, we have a new show on the feed. Long-time friend and contributor to the Zero Ambitions Universe, Lloyd Alter is taking the reins to look back at some of the fine work that Jeff has commissioned over the years, with a mind to making it more accessible to a wider audience.

    So, in parallel with the main show, Lloyd will be curating a tour through some of the best of Passive House Plus, interviewing the work's authors, and looking at the subject matter from a transatlantic perspective.

    This week we are joined by journalist Kate de Selincourt to talk about her 'Cold Truths' two-part feature, published back in January of this year. It might seem out of place to be discussing it in July, but these issues shouldn't just be seasonal because if we're only talking about them in winter it's already too late to act.

    Air quality matters, that's the subject for this week in our conversation with Simon Jones and it's all about ventilation. In this instance, Air Quality Matters is Simon's new consultancy offering outcome-focused ventilation strategy.

    Simon is a professional with nearly 20 years of experience within the housing, construction, and building services sector. He's an Associate Member of both The Institute of Environmental Science and the Institute of Air Quality Management, and; he's acted as an expert advisor to Government during the pandemic. And, there's more, so check his website and LinkedIn.

    The Buildings Action Coalition: collective action to accelerate progress in all areas of the built environment, with Scott Foster and Barbara-Ann Murphy

    This week we are spreading the word about the Buildings Action Coalition (BAC), a coalition of professionals from all areas of the built environment, from all over the planet, brought together to support a UN-backed global target for 'near-zero emissions and resilient buildings to become the new normal by 2030'.

    Mindful of this 2030 decline, the BAC is bringing professionals together to "turbocharge our progress and work together to make this a decade of delivery".

    Jeff was able to arrange for us to be joined by Scott Foster (former Director of Sustainable Energy for the UN Economic commission for Europe, and former guest of the podcast, alongside Barbara-Ann Murphy, CEO of The Enniscorthy Forum (the BAC's parent group) and a Local Councillor.

    This week we're joined by Gillian Campbell, the Communications and Public Affairs Lead at Existing Homes Alliance Scotland, a professional with a wealth of experience in the housing sector.

    Gillian has been involved in some really interesting work around influencing government policy around their retrofit strategy. In particular, their research has revealed insights that are relevant to anyone in the retrofit sector: from the need for good messaging, to the importance of timing in using it, and the fundamental need for frameworks that support and enable consumers to act. Whether the audience is a homeowner or asset manage, in Scotland or North America, the lessons are largely relevant to all.
