Shady business #1 – overheating, and Camden: we should think about solar gain all year round, with Zoe De Grussa (BBSA)

Zero Ambitions Podcast

It's all about shading, overheating, and solar gain with Zoe De Grussa this week. She's the author of that infamous Camden overheating case study that Jeff always references and, at the time of writing, is technical and sustainability consultant at the British Blind and Shutter Association (BBSA).

We cover Camden, but perhaps more interesting is the conversation around the difficulties in modeling shading, and the consequent difficulty in communicating its value to a project.

Despite shading measures being 3-4 times cheaper to install at the point of a building's origination, rather than retrofitting it when there's a problem, it's all too often one of the first things value-engineered out of the specification.
