In this episode, retrofit expert Bob Prewett describes how a client\u2019s brief for an \u2018extreme retrofit\u2019 in 2008 gave him \u2018something bigger than architecture to think about\u2019. Divided between London and Wells, the ten-strong practice has a portfolio of completed retrofit projects that achieve upwards of 70% energy savings and regularly monitors its buildings to understand how they operate over time.<\/p>\n
Although a founder member of the Passivhaus Trust, Bob observes that \u2018we rarely push all the way to Passivhaus which is a bit strong for many heritage buildings\u2019. Self-taught when retrofit resources, training and exemplar projects were scant, Bob explains the many ways architects can upskill today.<\/p>\n
