Adapting conservation area guidance for climate emergency

Episode 38. AJ Climate Champions with Hattie Hartman.In our second episode exploring how sustainability impacts heritage buildings, we speak to Procter-Rihl Architects’ Chris Procter, lead author of ACAN’s Climate Emergency Conservation Area Toolkit – England. Chris explains how conservation areas can streamline the consent process by developing a pattern book approach to building elements. Chris’ detailed audit of Islington’s Cross Street Conservation Area found that two-thirds of existing single-glazed windows could be suitable for double or triple-glazing, 44% of solid external walls could be wrapped in external wall insulation and over 30% of roofs could be fitted with solar panels. Chris also delves into the sensitive topic of window replacement, arguing that if existing windows do not conform to the original window pattern of a building, they should qualify for upgrading. He advocates development of a pattern book of details, complete with approved manufacturers, to simplify the consent process for building owners, relieve planners’ workloads, and speed up retrofit. Chris argues that this should be done locally based on specific building types. For show notes to this episode, go to www.architectsjournal.co.uk/podcasts
