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.

Notes from the show

• Zoe on LinkedIn
• The BBSA website
• The Home Energy Modeling Consultation
• Zoe's infamous academic paper: Overheating Camden Case Study. A London Residential Retrofit Case Study: Evaluating passive mitigation methods of reducing risk to overheating through the use of solar shading combined with night-time ventilation. (You can pay for a version here too, if you want.) 
• A BBSA video of the Camden case study
• Some new research from the Blinds Make Better Campaign, in collaboration with the University of Salford Energy House Labs
•  The Good Homes Alliance shading guide: Shading for Housing Design Guide for a Changing Climate
