Charlotte Douglas International Airport (CLT) is the USA’s 11th busiest airport (2019) ranked by passenger traffic and is undergoing rapid expansion and renovation. CLT had specific requirements for Concourse D lighting renovation:
Lighting concept: Improve the sense of space by replacing downlit general lighting scheme and puny perimeter uplighting. New luminous 7’ diameter ring pendants provide general illumination in up and down lighting. Uplighting reveals 30’ ceiling height and intricacy. Downlighting significantly increases light levels at the floor, a particular priority for the airport. Pendant shape re-enforces half-rotunda silhouette at terminus of concourse, the only of its kind at the airport. Indirect uplighting at perimeter in ‘CLT blue’ scheme or alternate white scheme adds cheery ambiance and unique identity.
CLT required tie-back to existing controls and daylight harvesting. Perimeter up lights have custom, separate boards (white / blue). This allows the option for color, but avoids a complex, expensive DMX system.
Specifying running-line luminaires, and modified luminaires with negotiated ‘fast-track’ production met tight time-line requirements. Illumination levels went from existing 8fc average to 30fc average.
Previously a very dreary and dark concourse, the lighting renovation lifted the space, both visually and
photometrically. Lighting levels now balance daylight contribution and feel well-lit and glare-free in the evening.
Legacy light sources were replaced with all-LED luminaires resulting in 42% better than code energy consumption.
