Learning from our mistakes? Looking back at ten retrofits, ten years later, with retrofit pioneer Marion Baeli (PDP, Passivhaus Trust)

This week we're with Marion Baeli, an architect who is a retrofit pioneer, a partner at PDP London, a board member of the Passive House Trust, and the author of seminal retrofit-related text Residential Retrofit: 20 Case Studies.

Some time ago we saw her posting about the impact DPEs are having on the property market in France and we realised that we had to have her on.

We talk about the imminent reprise of her book, a look back at ten of those case studies and the lessons learned since (that's how we justified the clickbaity "mistakes" in the title, it's more about lessons than mistakes, that's why we added the question mark).

We also discuss progress and the significant changes that the retrofit industry has seen since the book was first published in 2012 (air source heat pumps, as it turns out).

Obviously, we talk about EPCs and DPEs too.

What is Zero Ambitions Podcast?

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.

The success of the podcast has seen it grow into a consultancy, Zero Ambitions Partners. The consultancy works with blue chip clients, public sector institutions, and niche-market innovators that operate in the built environment, advising about the development and delivery of sustainability strategy and how it should be communicated.

Hosted by Jeff Colley (Passive House Plus), Dan Hyde (Everything is User Experience) and Alex Blondin (Everything is User Experience).
