Optimization of lighting design on façades of residential buildings of heritage interest

Researchers developed a novel algorithm to optimize lighting design for heritage residential buildings, demonstrated on Casa de Doña Jacinta in Córdoba's UNESCO-listed historic center. The approach minimizes intrusive light while maximizing spatial contrast and energy efficiency, leveraging DIALux simulations validated with quasi-real models and MATLAB digital metrics. Analysis of 302 luminaire positions revealed that accent lighting with non-uniform distribution—prioritizing solids over openings—enhances perception without compromising residential functionality. This scientific framework can be generalized to other heritage buildings, advancing evidence-based strategies for balanced illumination that preserves both aesthetic integrity and energy performance.
