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.

Enel X is the new Enel Group company dedicated to the development of innovative products and digital solutions for those sectors where energy shows the greatest potential for transformation: homes, businesses, cities and electric mobility.

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.
