Quantifying Architectural Aesthetics: Order and Complexity in Brutalist Facades
摘要
Brutalist architecture shaped the visual identity of cities during the mass urbanization period (1950–1975) but today is faced with challenges in aesthetic perception and energy efficiency policies. The EU’s Renovation Wave strategy calls for energy retrofitting of brutalist buildings, raising questions about preserving their visual identity. This study quantitatively analyzes the aesthetics of 15 Brutalist facades using methods based on Birkhoff’s and Eysenck’s formulas. Formal principles such as symmetry, repetition, contrast, graduation, color, material and strong center are applied to measure order, while complexity is assessed through hierarchical segmentation of facade elements. Statistical analysis demonstrates the potential of this method for assessing architectural aesthetics in the broader context of energy efficiency and heritage preservation.
