Jeff and Dan are joined by Dr. Peter Rickaby again. We were due a catch up so we recorded the conversation because he's always interesting. Peter should need little introduction, so we'll just say he's our favourite retrofit expert (sorry everyone else) and our most frequent guest on the show. He's only returned to the pod, not to the UK. In principle he's migrated to South Africa and is supposed to be retiring, but that's not exactly worked out so far. He has made it to Johannesburg though. Bu, if you haven't encountered him before Peter is one of the heads behind PAS 2035 and Ireland's BER system, amongst many other achievements. Go back and check the earlier episodes too.We had planned to talk about his experiences with the energy situation in South Africa and what we might learn from it but, as ever, we meandered all over the shop covering all sorts: retrofit, natural building materials, heat pumps, fabric first, fabric fifth, novel recycling, embodied carbon etc.Past appearancesRetrofit - Who do you trust?
