Abstract

Architectural facades critically shape affective perception in urban environments. Here, affect is understood as a multidimensional psychological construct encompassing valence (pleasure-displeasure) and arousal (activation-deactivation). Despite growing interest in affective responses to the built environment, the affective impact of urban architectural facades remains under-theorized. This study conducts a systematic review of 61 works, guided by the PRISMA framework, to identify which facade attributes most strongly predict affective responses operationalized as valence and arousal. Through multi-scalar synthesis and knowledge mapping, the review highlights complexity, materiality, symmetry, and bibliophilic integration as consistent predictors of affective perception across urban, building, and detail levels. Computational tools such as eye-tracking, CNN-based analysis, and parametric modeling are increasingly employed, yet remain fragmented and often overlook intangible dimensions like narrative coherence and cultural symbolism. By consolidating cross-disciplinary evidence, this review proposes a theoretical model linking physical design features to affective outcomes, and identifies methodological gaps, particularly the lack of integrative, mixed-method approaches. The findings offer a foundation for affect-aware facade design, advancing evidence-based strategies to support psychological well-being in urban contexts.
