Tailor-Made Lighting Design Project
Before initiating the intervention, the team of engineers and designers conducted a bespoke lighting study tailored to the Cathedral’s specific needs. The diverse activities within the Duomo have necessitated the implementation of a functional and flexible lighting system. This design prioritises adaptability to varied needs while remaining keenly attuned to the location’s scenographic and liturgical dimensions.
To minimise visual impact, lighting fixtures have been seamlessly integrated into the Basilica’s architecture, enhancing the space without disrupting its inherent balance. This deliberate choice allows for an enriched appreciation of the frescoes’ material and interpretive qualities, respecting their historical and artistic depth.
The core tenets of this project can be traced as follows:
- Light Direction: The team strategically opted for an alternating application of light sources, employing diffuse emission from the cornice upwards to accentuate the vaulted ceilings, alongside accent lighting to highlight cultural and devotional elements.
- Light Intensity: The implemented solutions enable localised diversification of luminous flux and the ability to modulate emission, creating a perceptual layering of light beams.
- Chromaticity: The designed illumination system facilitates the determination of the material recognizability of the mosaic surfaces.
Based on the findings of the lighting design study, indirect lighting was strategically employed to accentuate the arches and architectural lines, thereby establishing depth and a pervasive sense of spiritual ambience. Direct lighting was used to effectively illuminate pedestrian pathways, the refectory area, and designated reading spaces. Finally, particular emphasis was placed on highlighting artistic elements such as statues, paintings, and altars, with precisely calibrated light beams designed to enhance intricate details without causing glare.
Luminaire Selection and Layout
The light sources employ full-spectrum LED technology, which maximises the rendering of dominant colours. For optimal luminaire distribution, bespoke solutions were developed for the Cathedral’s distinct areas:
- Central Aisle: Primarily indirect lighting utilising small projectors discreetly positioned at the cornice level; within the Sacred Hall, spotlights were installed on capitols.
- Side Aisles: A combination of indirect and direct lighting employing small projectors arranged at capital level on the dome vaults.
- Transept: Indirect, direct, and accent lighting.
- Chapels: Accent lighting provided by small projectors seamlessly integrated at the cornice level at the base of the vault.
- Presbytery: Indirect, direct, and accent lighting employing small projectors to enhance architectural volumes and specific elements such as the high altar, crucifix, pulpit, and organ.
