This study proposes a methodology and proof of concept to target prioritize mass retrofitting residential buildings in the UK using open building datasets that combine fabric energy efficiency fuel poverty meet net-zero targets. The methodological framework uses series multi-variate statistical geospatial methods consider urban, socio-economic physical attributes. In addition, thermal imaging is implemented provide insights at scale. We define hard-to-decarbonize (HtD) metric enable clustering different types establish priorities. Using Cambridge, UK, as case study, five neighbourhoods were identified characterized help determine decarbonization intervention found one clusters HtD requires more policy support from government for implementation retrofit strategies. achieved has potential inform decision making. Of relevance, it applicable urban contexts.

Evaluating the recognizability of street built environments provides crucial support for urban planning, security monitoring and navigation. Although view images (SVIs) are widely used in studies, it overlooks interconnection among different locations, which can also affect perceptions about environmental recognizability. To address this issue, study proposes a deep learning-based model called RB-Node, comprehensively integrates spatial structural features road network visual from SVIs, achieving 82.56% accuracy. It appears that image information dominates Additionally, contributes significantly to accurate classification nodes waterfront promenade areas. Moreover, scene-text information, subset features, helps classify commercial historical Furthermore, 1056 samples were collected through an eye-tracking experiment validate evaluation results, as well compare decision-making process between humans RB-Node. According RB-Node behaviour human observed behavior follow similar patterns, although tend be more holistic than RB-Node's. This better understanding targeted recommendations renewal.
