Architectural Lighting Simulations as a Method to Evaluate Emotions on Cultural Heritage Building Facades

This research concerns the exterior lighting of historic buildings and cultural heritage monuments. Its objective is to organize a methodology for the study of facades, to record the individual or grouped morphological and decorative elements of the facades, and to organize the steps to achieve a presentation of different ways of lighting these elements. This presentation is made by an experimental digital lighting simulation, leading the researcher to discover the relationship between light and the architectural element being illuminated. Finally, the results of the simulations are evaluated by experts in the field of lighting, who attest to the emotions generated by the observation of the different lighting scenarios, while an attempt is then made to synthesize these results on an entire building facade, to determine whether this synthesis of the individual lighting effects is practicable. The analysis of the results reveals the trends in each lighting scenario, leading to a variety of emotions, whether they arise from a specific morphological element or from the entire facade.
