Zero Ambitions is a consultancy and weekly podcast about sustainability and the built environment. We find interesting and experienced guests who know what they're talking about, usually to discuss how we navigate the complexity of decarbonisation and sustainability in the built environment and its many related sectors. Hosted by Jeff Colley and Dan Hyde, publishers of Passive House Plus magazine (UK and Ireland), the podcast has now grow into a consultancy, Zero Ambitions Partners. The consultancy specialises in defensible sustainability communications. We create the strategy that makes built environment leaders stand out, enabling them to occupy positions that are distinct and defensible. As with the podcast itself, we help organisations to communicate about what they do and the value that they offer. Usually, this means strategies to change a conversation from price to value and how to futureproof an offer with evidence that makes its claims watertight. If you're a leader, or want to become one, we help you to make sense of where you stand in your sector, how to improve your positioning, how to communicate this to the market you operate in, and how to highlight the difference between you and your peer group. If you can engage your value chain by speaking about what matters to them, you can educate your key stakeholders and turn them into evangelists for your cause. Book a ZAP Defensibility Audit, but brace yourself - Uncover value and opportunities that you may not have recognised - Find out if your sustainability claims are defensible - Find out if your claims are too meek - Change the conversation from price to value Language: en Genres: Documentary, Education, How To, Society & Culture Contact email: Get it Feed URL: Get it iTunes ID: Get it |

The reluctant house builder: Greencore is building homes that challenge expectations of what a house can deliver, and the performance modelling in PHPP, with Ian Pritchett (Greencore Homes)
Episode 194
Tuesday, 5 May, 2026
We are joined by Ian Pritchett of Greencore Homes to talk about his science-based approach to green building and the work that has led him from developing green building materials becoming the co-founder of a vertically-integrated developer and house builder.There's a lot of history and legacy to cover because Ian has been in the green building game for decades and it's this that has informed the approach being taken right now.Greencore is also challenging the Passive House Institute about the accuracy of its PHPP (passive house planning package) modelling software because their homes outperform the model's predictions because of their use of phase-change materials.Be warned, this is nerd business—Jeff gets to interrogate the build up specification—but it doesn't get too technical to be able to follow the thread.Notes from the showThe Greencore Homes website Ian Pritchett on LinkedIn A PH+ article about Neil May**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, 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 Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**
