Most glazed facade
Part O 2021 (England), Technical Guidance, July 2022 – Final Draft, published on the Future Homes Hub, defines most glazed facade as: ‘defined in AD-O and used in the Simplified Method to mean the façade with the largest m² area of glazing, which then determines the applicable glazing and free area targets. Note that in blocks of apartments or other buildings with multiple homes, this has to be considered on each individual home, not for the whole building.’
