The reach of LED technology is making its way to ancient cathedrals of all places. One cathedral that is utilizing the latest LED lighting technology, to not only improve the experience for visitors to the cathedral, but to also save on energy costs is the Milan cathedral in Italy. In preparation for this years long awaited EXPO 2015, the organization that manages the cathedral has been investing heavily in switching the facility over to LED lighting. LED testing expert, Gooch & Housego, explains.
Local Lighting Designers Presented With a Unique Problem
Local lighting designers Ferrara Palladino e Associati were commissioned to help convert the Milan cathedral over to LED lighting. Their task was to replace the current spotlights and lenses with an LED system that complemented the historic features of this wondrous structure, as well as to reduce the operating costs for energy usage going forward.
The old lighting system consisted of 175 flood lights each with 400w lamps that were strategically mounted at the base of the cathedral to provide a uniform illumination of the inside of the structure. While this solution was economical during its day, it has long become obsolete thanks to all of the advances in lighting technology.
Lighting designers chose LED lighting technology from ERCO, which included LED lenses that allowed new design opportunities. The old lighting system used a cool color that resembled daylight, while the new LED system uses LEDs with 4000K outputs that offer a calmer ambiance and make the ancient structure look more natural.
Significant Cost Savings With LED Lights
This project was able to cut energy usage by almost two thirds, going from 70kW to 23.7kW. This large drop in energy usage earned the project an A+ energy efficiency rating as well as an Environmental Friendly Innovation Award by Italian organization Legambiente.
Future is Bright for Historic Buildings
As was the case with the Milan LED lighting project, other historic buildings should take note of the energy savings, as well as the aesthetic improvements, that can be seen with LED lighting.
