Actions in emblematic buildings
These are some of the lighting projects in emblematic buildings that Fundación Iberdrola España has been involved in:
Los orígenes de este The origins of this church date back to the late 12th and early 13th centuries, when it was originally part of the fortress of the Knights of Calatrava. The façades have two sturdy buttresses and several doors. The Plaza de España gate opens into the southern façade which looks on to the “Puerta del Sol”. It dates from the second half of the 15th century and is dedicated to the Assumption.
This church is in the Isabelline Flamboyant Gothic style. The so-called “Puerta de los Catecúmenos“, of possible Romanesque origin, appears framed by a lintel that housed an image of the Pietà.
This project is, currently, in the execution phase.
We have participated in the project to modify the lighting of the Army Museum’s collection, which needed to address the interior lighting in its display cases, the paintings and panels and the Flags-Artillery-Arms collections, as well as to set up certain spaces to accommodate collections. This project reduced energy consumption and optimised the chromatic reproduction index and reliability of the control system.
To improve the interior lighting in the display cases, we replaced fluorescent luminaires with LED lights and changed the smart control system for another with a timer as well as undertaking subsequent modifications to the electrical panels.
Due to the large number of collections on display, we have fitted out different rooms that were not previously equipped to hold exhibitions. To do this, we installed suspended rails with indirect LED lighting to the ceiling and specific rails that allow adjustable LED spotlights to be placed below them.
In order to enhance the lighting of certain paintings and panels, new rails were installed, existing ones were enlarged and an appropriate number of spotlights supplied. Finally, the lighting for the Artillery, Flag and part of the Arms collections involved the installation of suspended rails with indirect LED lighting to the ceiling that also allowed adjustable LED spotlights to be placed below them.
We replaced fluorescent luminaires with LEDs and changed the smart control system to improve the interior lighting in the display cases.
The installation of the new exterior lighting for the main portal in the southern façade of the Monastery of the Order of Santiago in Uclés, Cuenca, involved renovating the decorative lighting to highlight, on the one hand, the volume of the façade and, on the other, the architectural details of this monument that was built in 1735. This initiative also included the lighting of the keep in Albar Llana Castle, an old fortress of Arab origin located close to the monastery.
The design of the decorative lighting for this Churrigueresque doorway, which is attributed to Pedro de Ribera and is one of the best preserved Baroque examples still existing, combines flood lighting that highlights the general volume of the façade and spot lighting that highlights its architectural details. The combination of optics and colour temperatures in the selected floodlights helps to enhance the unique elements.
This project involved the installation of a total of 18 LED luminaires, with a total power rating of 1,640 W, with a reduction of 55% compared to the previously installed lighting. This will result in significant savings in energy expenditure and avoid the emission of up to one tonne of CO2 into the atmosphere annually.
We inaugurated this project on 9 May 2018, along with the Diocese of Cuenca, in a ceremony attended by José María Yanguas (Bishop of Cuenca) Emiliano García-Page (President of the Regional Government of Castilla-La Mancha), Ignacio Galán (Chairman of Iberdrola ) and Félix Sanz Roldán (Secretary of State Director of the National Intelligence Centre).
The renovation project for the new decorative lighting for the Royal Pantheon in San Isidoro de León Collegiate Church was undertaken thanks to a collaboration agreement that we signed in 2017 with the San Isidoro de León Collegiate Church Chapter. The objective of this agreement was to develop and execute a lighting project to highlight the outstanding nature of this chapel, which was built in the 11th century, and the cultural assets it hosts.
The lighting project in detail
LED spotlights were used with over 98% colour rendering, which makes it possible to achieve full colour fidelity at a colour temperature of 3000 ºK, which is very similar to sunlight. It is also interesting to note that the benefits of LED technology were fully utilised, as this type of lighting is kinder to paintings since it does not emit infrared or ultraviolet light.
The design of the decorative lighting of the vaulting uses interlaced beams of light to ensure perfect uniformity as well as avoiding high light concentration at the source of the beams, thus lessening the light levels the paintings are exposed to.
In addition, three natural light sensors were installed to automatically adjust the light level in the Royal Pantheon’s interior. This was achieved by installing a centralised control system to regulate light intensity.
This lighting project was inaugurated on 18 April 2018.
About the Royal Pantheon in Saint Isidore church
Located at the foot of the Collegiate Church, it has a quadrangular plan with three naves and two central columns. The capitals have a variety of decorations; some have zoomorphic figures, others have vegetable decorations and two of them have evangelical scenes -the resurrection of Lazarus and the healing of the leper.
The kings and queens of León were buried here in the Middle Ages. It is decorated with highly important paintings, both in terms of their quality as well and also for their state of preservation, leading it to be called the “Sistine Chapel of Romanesque art“.
- The paintings portray different religious scenes and the arcades are decorated with ornamental elements. The paintings in the vaulting include: the Annunciation, the Slaughter of the Innocents, The Last Supper, the Trial and Passion of Christ, the Book of Revelation and the Prologue, and the Christ Pantocrator, all of them in an excellent state of conservation.
LED spotlights were used for this lighting project to provide a totally reliable colour perception and uniform illumination with crossed beams.
Together with the Royal Tapestry Factory, we have renovated the lighting system in the restoration workshop of this institution, which was founded at the beginning of the 18th century by King Philip V. The installation concluded a comprehensive transformation process using the most advanced LED technology in line with the workshop’s needs and importance. The new workshop lighting system will reduce electricity consumption by over 47% and save CO2 emissions of close to 3.5 tonnes per year.
It is expected that this new and modern technological solution will set a precedent among restoration facilities, as it has not yet been applied to many factories in the world and, especially textile factories. The project provides ideal lighting to preserve textiles, thereby improving efficiency and the conservation conditions for the pieces in the workshop.
Cutting edge LED technology
This new lighting has the most modern LED technologies, which guarantees the sustainability of the installation, one of the main objectives for Iberdrola within our commitment to caring for the environment and the fight against climate change.
- For the workshop lighting project, a total of 28 sustainable energy-efficient LED were installed, the lamps were suspended from the ceiling, significantly increasing lighting levels in the room.
- The lighting has been further enhanced at six work benches, through the design and assembly of made-to-measure metal structures that ensure colour rendition in excess of 98%, and over 80% light uniformity. These structures also include the possibility of regulating the light level, according to the needs of each restorer. Prior to the project, the lighting consisted of 28 halogen bulbs and eight fluorescent lights with a total power of 11,488 W. After the renovation, it has been possible to reduce consumption by more than 47%.
- Lastly, a new lighting system has been installed in the Dyeing Room, featuring 12 LED lamps which provide the same colour temperature and rendition as in the workshop.
This project was undertaken thanks to an agreement we signed with the Royal Tapestry Factory in 2017 to renovate the restoration workshop lighting, continuing a collaboration that began in 2013 with the Restoration of the tapestries of the Patriarch in the Royal College of Corpus Christi in Valencia.
About the Royal Tapestry Factory
Founded in 1721, the Royal Tapestry Factory has 300 years of experience in the production and restoration of tapestries, carpets, and ornamental embroidery.
In the early 18th century, the Factory was the European benchmark for luxury fabrics, thanks to the collaboration between weavers and renowned painters, such as Goya, Mengs, and Bayeu. In 1889, the urban growth of Madrid forced the factory to relocate to the outskirts of the capital: the site chosen was an olive grove and orchard known as Atocha, where the Royal Tapestry Factory is still located to this day.
In 1996, the institution became the Royal Tapestry Factory Foundation. The Foundation is dedicated to preserving handicrafts, the conservation and restoration of Spain’s textile heritage, and the general promotion of all cultural activities that contribute to an understanding of the art of tapestry.
The new LED lighting guarantees the sustainability of the installation and helps the restorers to carry out their work in greater comfort.
In 2016, Fundación Iberdrola España and the Cathedral Chapter signed an agreement to update the lighting in the Chapel of the Holy Chalice, thus continuing a collaboration that began in 1999 with the lighting of Valencia Cathedral. A total of 38 spotlights and 28 metres of highly efficient and sustainable LED technology strips were installed, substantially improving the overall lighting in the room. Two specific lights for the reading area were added and the fluorescent lights in the niche of the Holy Chalice were replaced. Previously, the lighting consisted of 28 halogen and fluorescent bulbs with a total power rating of 4,500 W.
After the renovation, electricity consumption was reduced by over 60%. In addition, the versatility of this new installation allows the chapel to be partially lit, so daily power use will be less. A control system with a touch screen has also been installed to programme the illumination of the scenes in the altarpiece, or areas in the chapel.
The project’s decorative lighting design centred on a series of elements: the ribbed vault, the front of the alabaster altarpiece, the niche containing the Holy Chalice, contrast lighting for the altarpiece, illumination in the area around the altar and general illumination in the chapel. This design combines cold white and warm white lighting to highlight specific elements and the existing rails have been reused respecting their location, thereby minimising impact on the walls.
The project, which also included the cleaning of the alabaster altarpiece prior to its lighting, was inaugurated by Ignacio Galán, Chairman of Iberdrola.
Chapel of the Holy Chalice in Valencia Cathedral
The Chapel of the Holy Chalice was built between 1365 and 1369. It measures 13 metres wide by 16 high and is covered with a high ribbed vault in the shape of a star whose ribs extend to rest on polychrome corbels. In 1916, the Holy Chalice was moved to the chapterhouse, which became the current chapel.
The chapel is in the Flamboyant Gothic style (14th century). It has a square floor and smooth walls, of carved stone. The twelve Apostles and the Coronation of the Virgin Mary in heaven after the Assumption are represented in the vault’s keystones. The cathedral is dedicated to the Assumption.
This space was not affected by the neoclassical refurbishment in the 18th century when the alabaster altarpiece was placed in the 15th century choir entrance. On the walls it is possible to see the Adoration of the Kings, a fresco painting by Nicolás Florentino (1472), and the chains that closed the port of Marseilles, which were brought to Spain by Alfonso V the Magnanimous in the 15th century.
The lighting project for the Chapel of the Holy Chalice included decorative lighting which combines lighting in cold white and warm white.
The new architectural lighting for the main façade of Irún Town Hall has achieved an energy efficiency of 83% compared to the previous lighting, thanks to the new system that we implemented in 2017. Built in the 17th century, this Baroque building has a main façade made of stone ashlar with keystones on the ground floor and corners, topped with a stone cornice on which there is a balustrade divided by a large shield carved from limestone. On the ground floor, a five-arched arcade gives access to the interior of the building; and crowned effigies appear on each of the arches. On the main floor, there is a large balcony, supported by corbels, onto which five doors topped with pediments open.
As a result of an agreement signed in 2016, the goal was to design the decorative lighting according to aesthetic and efficiency criteria, using LED technology and, particularly, RGB luminaires that allow dynamic colour changes and the programming of different light scenes. As well as the general lighting, the intention was to create a contrast between areas such as the porch and balustrade, and to use the lighting to accentuate particular elements such as the coat-of-arms that crowns the upper floor.
This project consisted of the design and installation of a decorative lighting system that met aesthetic and energy efficiency requirements.
We installed 11 500 W floodlights, which use less electricity than a domestic microwave, 12 120-cm strips and 31 metres of RGB-technology LED strips that will allow dynamic colour changes. The design is completed with a control system using a DMX installation which allows the colour scenes and combinations to be programmed from a touch screen within the building, making the control system easy to operate.
Towards the end of 2016, we signed a collaboration agreement with the General Directorate of Fine Arts and Cultural, Archive and Library Heritage, part of the Spanish Ministry of Education, Culture and Sport, to plan and execute an architectural lighting project for the church of the Royal Monastery of Santa María in El Paular.
Following the signing ceremony, we began the renovation of the decorative lighting within the monastery’s church, which began to be constructed in 1390 and would take several centuries. LED technology was used as the basis for this project in order to meet the sustainability and energy saving criteria. But the project’s main objective was to enhance its unique elements, specifically the 15th century altarpiece, the ashlar masonry and the vaults, by means of general and accent lighting.
The project was based on technical criteria including:
- To give the length of the nave a sense of continuity with lighting above the top cornice at the base of the vaulting to provide overall medium illumination and avoid excess light in the area, respecting the atmosphere of the surroundings and the natural light.
- To avoid glare and light pollution and reduce intrusive or unpleasant lighting.
- To achieve a design that could ensure that the installation could be easily maintained.
As the altarpiece is the church’s most important element, the lighting design was versatile and dynamic to cover the different uses made of the church: worship, sightseeing, events, etc. A total of 28 spotlights were, therefore, installed which provide more subdued general lighting and partial, accent lighting for different scenes in the altarpiece, which aid informative descriptions during tourist visits.
To make this dynamic illumination of the different scenes on the altarpiece possible, a control system was installed incorporating a programmable touch screen with editing via buttons to adjust the visual effect in the different areas of the church and altarpiece, together with software that allows it to be programmed from a computer or mobile telephone using a custom-made app. The programming system installed is designed to make it compatible with the different uses of this holy place (worship, tourism, events, etc.).
Finally, the total power required for the new church illumination is just 2.4 kW, compared to 9.1 kW for the former lighting. From an environmental point of view, this greater energy efficiency reduces CO2 emissions by 2.1 tonnes annually.
Special attention was paid to the altarpiece during this project as it is the most important element in the church; a total of 28 spotlights were installed around it to provide general and partial lighting.
One of the most important initiatives undertaken under the agreement between Iberdrola and the Fundación San Sebastián 2016 – Capital Europea de la Cultura was the project to provide the decorative lighting for the main façade of the Donostia/San Sebastián Town Hall. Fundación Iberdrola España designed and implemented the project as part of our Lighting Programme.
The objective of this project was to provide architectural lighting that would bring the town hall’s main façade to life at night (the town hall was built in 1887). To achieve this, the latest generation LED luminaires were installed, as these are characterised by their efficiency and the quality of their chromatic reproduction. In addition to controlling the night-time glare and light pollution, they also reduce intrusive or unpleasant light.
At the request of the City Council, the project was based on RGB luminaires and the DMX data system that allows coloured lighting to be used and different lighting scenes to be programmed. The lighting is produced from luminaires placed around the building, in particular, among its ledges, cornices, balusters, etc., which, due to their size, can house the necessary luminaires.
The project’s aim was to provide architectural lighting that would bring the town hall’s main façade to life at night.
We financed this project with 45,000 euros to roll out new exterior decorative lighting for the Palace of the Spires, located in the historic centre of Logroño and which currently houses the headquarters of the Riojanos Study Institute (IER). The design of the project aimed to highlight the monument’s façade, enhancing its architectural and volumetric compositions through the installation of 98 LED technology luminaires.
The decorative lighting for the Palace of the Spires aimed to highlight the historic building’s architectural and volumetric compositions.
Distributed across the building’s five levels, the luminaires highlight elements such as its windows, cornices and spires, taking care to integrate them into with the surrounding urban environment. In addition, the total installed power for this decorative lighting is only 1,800 W, ensuring greater energy efficiency and a reduction in the maintenance cost for this 16th century palace, which is one of the most emblematic buildings in the capital of the La Rioja region.
The lighting system in several of the rooms at the San Fernando Royal Academy of Fine Arts needed to be renewed and the fluorescent luminaires replaced with LED technology. Through our support, we have contributed to this transformation, which has resulted in the following advantages:
- An improvement in the appreciation of the exhibited works, allowing them to be admired in all their fullness, which implies a more enriching experience for visitors.
- An improvement in the protection for works exposed to the light.
- Reduced energy consumption compared to conventional lighting systems.
- A decrease in polluting effects, with the consequent benefit in terms of environmental conservation.
The use of LED lighting in a museum setting improves the conservation conditions for the works of art as the luminaires do not emit infrared or ultraviolet radiation. The luminaires light up instantaneously and their performance is not influenced by the number of on/off cycles they are subjected to. They also produce light with a visual effect that is nearly equivalent to that of natural light and they reproduce colours with great fidelity, with a chromatic index of 80 out of 100. Another added advantage is that LED luminaires do not generate as much heat as traditional systems, an essential requirement in a museum to achieve energy savings on seasonal air conditioning.
In the museum, general ambient lighting was combined with partial, accent lighting, to highlight the works of art. Visitors now perceive a uniformly-lit serene space free from the shadows, which can be caused by overhead lighting, recreating the appearance of natural light. For the accent lighting, LED spotlights were used for those works that required it due to their importance or aesthetic qualities.
The combination of general ambient lighting with partial, accent lighting, highlights the works of art.
LED lighting offers different shades of light (from cold to warm) that can be adapted to all types of environments. In the museum, cold lighting has been chosen, since a detailed analysis of the colour spectrum guarantees that blues and reds are reduced, the resulting light is as close as possible to natural light, thus improving the perception of the works of art.
Built around 1180, this Mudejar building has five naves separated by pillars on which horseshoe arches rest and it stands out for the contrast between the sobriety of the synagogue’s exterior and its elaborate interior.
The lighting project carried out was unique due to the building’s characteristics. The aim was to provide the synagogue with modular lighting that allows:
- The tonality of the white light to be varied to simulate daylight depending on the time of day.
- Different scenes and transitions to be created.
- Contrasts to be made between the up lighting from the ground and the down lighting.
Visitors are, therefore, able to experience how light modifies the perception of the monument.
Individual or different scenes in the synagogue’s lighting can be controlled or programmed from a touch screen.
Fundación Iberdrola España, therefore, designed custom-made luminaires that combined the latest generation LEDs with three different colour temperatures: from 3000 ºK, which produce a warm light close to gold, passing through 4000 ºK, with a neutral white, up to 6000 ºK, whose emission is a cold white light close to blue.
A total of 174 light sources were installed: 54 spotlights in the paving at the base of the columns and 120 strips installed in the upper arches. In addition, each of them can be individually controlled, or different scenes can be programmed that are activated from a touch screen located in the visitor control centre.
We collaborated in lighting the eastern section of Vilafamés Castle walls. The design incorporated the highest standards of efficiency and used state-of-the-art luminaires (LED). All with the aim of avoiding unwanted glare and light pollution, as well as to highlight and enhance the canvases provided by the walls.
Declared an Asset of Cultural Interest, Vilafamés castle and its walls date back to the 14th century. The castle stands in the highest part of the town and overlooks the plain from a height of 400 metres. A small part of the ancient town still survives around the castle.
The project resulted in uniform and environment-friendly lighting. Thanks to this initiative, the electricity consumed by the bridge’s lighting system has decreased by 84%, after the installation of 36 LED-technology lights. In addition, the new layout of the lighting will highlight the horizontal nature of the bridge structure, thus reducing light pollution. This new lighting makes it possible to spend less on maintenance work, since these lighting devices have a lifespan of over 10 years.
With the aim of enhancing the bridge’s architectural elements, the new lighting combines general lighting of the sides of the 195-metre bridge with specific illumination for the six arches, including the central triumphal arch, which reaches a height of 14 metres.
A total of 36 low consumption luminaires were installed.
- Of these, 24 were placed on the sides and bridge abutments (replacing the previous ones), with the intention of emphasizing the horizontal nature of the monument, thus maintaining the projection from a distance while reducing both light pollution and the power rating of the lighting.
- The other 12 light fittings were located in pairs in the inside support of each arch, to reveal the hidden side of these elements and cause them to be reflected on the water of the Tagus.
- LED technology luminaires were used, which provide for the future sustainability and energy savings of the installation.
- Glare and light pollution were limited and intrusive or unpleasant light reduced. This was achieved by lowering the power rating and regulating the lighting based on the reflection of the light according to the formal characteristics, roughness and material of each illuminated element.
- The current projection from a distance was combined with the placement of new spotlights inside the bridge arches, to provide definition and generate a new, more architectural concept, based on specifically enhancing certain of the bridge’s compositional elements and locating some of the lights on the bridge itself.
- The installation’s control and protection system was reduced.
- 84% energy efficiency.
The project has allowed the bridge’s architectural elements to be enhanced, with both general lighting of its sides and focused lighting of the arches.
We took care of the financing, design and installation of the new lighting in this Renaissance church that, nevertheless, is based on Gothic patterns in its construction and forms. The project fulfilled its objective of lighting the altarpiece, the altar and the presbytery.
We installed 40 35-watt LED spotlights, which illuminate vertical rails located on both sides of the presbytery for the main lighting, an LED arc and four mini LED spotlights, also for lighting the niche and the Virgin.
The spotlights have smart controls that allow them to be controlled and programmed. Four scenes were programmed with different lighting levels: these can be switched on depending on the importance of the event, activating them from a touch screen located in the installation’s control cabinet. The total installed power is 1,452 watts and the actual power consumed depends on the scene that is on at any time.
In 2014, we concluded the works on the exterior lighting for the main façade of the San Bernardo Chapel Complex in Oropesa. Known popularly as ‘La Compañía’ the complex has been declared a Site of Cultural Interest and is currently used as a cultural centre.
The Congress of Deputies building was fitted with a new low consumption LED technology lighting system in 2014. Thanks to an agreement promoted by the former first vice-president of the Lower Chamber, Celia Villalobos, which was signed in September 2012, Fundación Iberdrola España financed, designed and installed the new exterior artistic lighting system, which has an installed power rating of 1,400 watts and is 25% lower than conventional bulbs.
This LED lighting makes the building stand out at night from its surroundings in the Plaza de las Cortes by highlighting this neoclassical building’s most significant elements. This project has not only brought the Congress building to life at night, but it also opted for sustainability and energy saving by installing low consumption luminaires. The project inauguration ceremony was attended by the former president of the Congress, Jesús Posada; Iberdrola chairman Ignacio Galán and the president of Fundación Iberdrola España, Manuel Marín.
