Le soluzioni studiate per i due ambienti dell ’ Abbazia hanno portato a due sistemi di illuminazione distinti : uno di tipo artistico / museale e uno di tipo funzionale . Il primo è stato realizzato utilizzando piccoli proiettori a LED di ultima generazione , flessibili e professionali , grazie ai quali è possibile modificare la messa a fuoco , l ’ ampiezza e il tipo di fascio luminoso . Ogni proiettore è in grado di modulare autonomamente l ’ intensità della luce fino al suo completo spegnimento . I led sono stati collocati su un binario elettrificato che permette di spostare e riposizionare i proiettori , qualora ci sia il bisogno di cambiare l ’ illuminazione del refettorio . Durante i lavori è stata prestata particolare attenzione all ’ illuminazione dell ’ affresco del Cenacolo di Domenico Ghirlandaio , l ’ opera più importante presente all ’ interno dell ’ Abbazia .
L ’ illuminazione funzionale del refettorio è stata alimentata grazie a tubi led lineari posizionati sui tiranti già esistenti all ’ interno della struttura ; nella sala d ’ ingresso invece sono stati installati dei proiettori a led posizionati lungo le pareti dell ’ ambiente . Tutti i corpi illuminanti posizionati da Enel Sole hanno una temperatura di colore pari a 3.000 gradi Kelvin e l ’ intero impianto , grazie a una potenza complessiva pari a 1,05 kW minore rispetto ai quasi 4kW del precedente , consentirà di ottenere un risparmio energetico di oltre il 70 %.
L ’ impianto elettrico è stato realizzato con un cavo in rame ad isolamento minerale posato a vista , senza intaccare i manufatti esistenti , che garantisce flessibilità , facile rimovibilità e possibilità di utilizzare meno porzioni di cavo rispetto a quelle usate dai tradizionali cavi in gomma . I lavori sono stati effettuati nel pieno rispetto delle prescrizioni indicate dalla sovrintendenza , tra le quali il posizionamento esclusivo di tutti corpi illuminanti sui due tiranti presenti nella sala del refettorio e quelle dei proiettori presenti nella sala d ’ ingresso . Tali operazioni sono state necessarie per non intaccare la struttura di grande pregio sia architettonico che artistico .

Through an open and flexible service platform , Enel X is able to connect urban ecosystems , industrial districts , production chains , mobility needs and individuals . It offers solutions aimed at major clients with a particular attention to flexible services such as consultancy , technologies related to energy efficiency , distributed production and implementation of off-grid solutions and Demand Response . It is also aimed at residential clients , with the installation and maintenance of advanced technological solutions for smart homes , capable of saving more energy and offering greater well-being . In the e-mobility field , Enel X covers all types of clients with the aim of becoming a technological leader in the sector , to promote an increasingly widespread and efficient electric mobility with recharging infrastructures and Vehicle-Grid-Integration . It also provides integrated services to public administrations and municipalities , and connectivity solutions such as the wholesale offer of fibre optic services .
To give new light to cities , countries and some of the most important artistic places in Italy – such as museums , churches and archaeological parks – is the commitment of Enel Sole , the company of Enel X whose core business is the development of the public and artistic lighting sector and of everything connected to it . In 2017 , more than 35 municipalities have relied on the company ’ s solutions , adding to the over 3300 Italian cities that over the years have chosen it to renovate their public lighting systems .
An example in the field of artistic lighting is the recent renovation of the lighting system of the refectory and entrance hall of the Abbey of San Michele Arcangelo in Badia a Passignano , realized thanks to the collaboration between Enel X , Lions Club International and the Community of Vallombrosian Monks .
The solutions studied for the two halls of the Abbey led to two distinct lighting systems : an artistic / museum one and a functional one . The first was made using latest generation small LED projectors , flexible and professional , thanks to which the focus , the width and the type of the light beam can be changed . Each projector is able to autonomously modulate light intensity until it is completely switched off . LEDs have been placed on an electrified track that allows the moving and re-positioning of the projectors when the lighting of the refectory has to be changed . During the works , particular attention was paid to the illumination of the Cenacle fresco by Domenico Ghirlandaio , the most important artwork in the Abbey .
The functional lighting of the refectory is provided by linear LED tubes positioned on the existing tie rods of the structure ; in the entrance hall , LED spotlights have been installed along the walls of the room . All the lighting fixtures positioned by Enel Sole have a colour temperature of 3,000 K , and the whole system , which is 1.05 kW less powerful than the 4kW of the previous one , will allow an over 70 % energy saving .
The electrical system has been realized with a copper cable with mineral insulation laid in view , without affecting the existing structures ; this guarantees flexibility , easy removability , and the possibility of using fewer portions of cable compared to those used by traditional rubber cables . The works were carried out in full compliance with the requirements indicated by the superintendency , including the positioning of all lighting fixtures exclusively on the two tie rods in the refectory room and of the projectors in the entrance hall . These operations were necessary in order to not undermine the structure , which has a great architectural and artistic value .
