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.Notes from the episode
