“City of Light”

A New Lighting Concept for Lüdenscheid In Germany

We are delighted to announce our commission to develop a comprehensive lighting concept for the city of Lüdenscheid, North Rhine-Westphalia, Germany.

This project marks a new step in strengthening the city’s international identity as the “City of Light”—a title rooted in its rich industrial heritage and global reputation in lighting technology. Lüdenscheid is home to leading companies such as ERCO, Insta, and DIAL, as well as the acclaimed „Lichtrouten“ Light Art Festival, which has brought world-renowned light artists to the city for many years.

Guidelines for optimising commercial outdoor lighting

Guidelines for optimising commercial outdoor lighting

Our lighting design for a dark sky

Sustainable and environmentally friendly outdoor lighting for commercial and industrial areas offers great potential. Our guide to optimising commercial lighting reduces light pollution – while maintaining safety and efficiency.

The basis is a study carried out by Ruairí O’Brien on behalf of the Brandenburg State Office for the Environment in the Premnitz Industrial Park, located in the Westhavelland Nature and Star Park (approx. 70 km west of Berlin). The region was recognised as Germany’s first star park in 2014 and is committed to preserving natural nocturnal landscapes through responsible lighting. The measures presented here were developed in collaboration with two local companies and serve as a model for other locations.

Core measures:

  • Targeted lighting (only where necessary)
  • Optimised light distribution (minimised light spill)
  • Shielding against stray light
  • Reduced reflection (through darker surfaces)

Advantages:

  • Environmental protection (nature, night and climate)
  • Cost reduction (lower energy consumption)

The guideline serves as a model and is suitable for commercial and industrial areas.

Dresden International Airport – Departure terminal lighting concept

Dresden International Airport – Lighting concept for the departure terminal

Our lighting concept for Terminal 1 at Dresden International Airport aims to build a bridge to the future. In addition to technical lighting to ensure traffic safety, precise light differentiation of individual areas, levels and elements helps travellers find their way around.

The architectural lighting design emphasises the spatial quality and the unmistakable industrial architecture of the terminal and underlines the uniqueness of Dresden Airport. It supports the positioning of the airport as a modern, open and future-orientated location of international stature.

The lighting concept combines technical lighting and light art to visually depict themes such as flying, the sky and mobility and to create a symbolic link between the past, present and future. This concept gives the previously anonymous hall a narrative dimension that offers a special experience for air travellers from all over the world.

The flying carpet“,(a carpet of light) consisting of numerous curved downlights under the hall roof, creatively provides adequate illumination of the floor and creates a unique aesthetic. A “cloud of light immerses the entrance hall in dynamically changing lighting moods and uses reflective moving elements to create a constantly changing interplay of light and shadow, which has a fascinating effect both in natural daylight and with artificial lighting.

A light and glass sculpture, made of holographic and dichroic elements, enables visitors to be symbolically beamed into the universe.

Design guidelines for Lehnin Monastery

Design guidelines for Lehnin Monastery

Kloster Lehnin is a municipality in Brandenburg, about an hour from Berlin city centre. The district of Lehnin owes its origins to the former Cistercian monastery, the oldest monastery in the Mark Brandenburg, which was founded in 1180 and secularised during the Reformation in 1542. Since 1911, it has been home to the Luise-Henrietten-Stift, a Protestant deaconess house.

Our task is to draw up a design guideline for the town planning office to guide the future development of the neighbouring buildings, houses and businesses in the small town of Lehnin in harmony with the listed monastery ensemble. The aim is to preserve the architectural heritage and at the same time enable the use of contemporary technologies, such as the integration of photovoltaics. A key issue is the sensitive positioning and installation of solar modules in the historic roofscape and the preservation of Lehnin’s special street character, including the protection and adaptation of the vegetation in the townscape with regard to climatic changes.

We carry out the necessary on-site surveys and inspections and liaise with specialist authorities. In addition, we support the municipality in the implementation of the process, assist with public and official participation, prepare draft texts for announcements and meeting documents and analyse the comments. The project period runs from April 2024 to December 2024.

Lighting design for the new Kunstguss Lauchhammer experience centre

We are pleased to announce that we have been selected to join the team of experts working on the ambitious “Transformation 1.535°” project in Lauchhammer, Brandenburg, Germany. This extensive project spans two sites: “ERZ” (ORE) with art casting museum, art foundry and Friedenskirche in Lauchhammer-Ost (13.8 ha) and “KOHLE” (COAL) with bio-towers, activated sludge basin and relic park in Lauchhammer-West (32.2 ha).

Our contribution to the planning and development team is the creation and implementation of the lighting concepts for the public space, the landscaping, the art casting museum, the new “Education and Experience Centre for Art Casting and Industrial Culture” and the famous listed bio-towers (see picture).

The “Transformation 1.535°” project is one of the most ambitious cultural and tourism initiatives in Germany, if not in Europe. Its aim is to transform the remnants of East Germany’s coal industry history into a vibrant centre for art, education and tourism.

An important part of this project is the expansion of the Lauchhammer Art Casting Museum into an “Education and Experience Centre for Art Casting and Industrial Culture”. This centre will honour the region’s rich industrial heritage while promoting modern educational and cultural experiences.

The Biotowers, a unique and impressive example of East German industrial culture, are at the centre of this transformation.

These structures, which once bore witness to the region’s industrial prowess, will be brought back to life through exhibitions, information programmes and innovative lighting concepts so that they can be preserved and appreciated for future generations.

We are delighted to be able to contribute to this epoch-making project and to contribute to its sustainable and holistic success with our expertise in the communicative and aesthetic power of architectural lighting design.stay tuned for more updates on this exciting journey!

Food Court GUC-German University in Cairo

Food Court GUC

Shade roof Food Court GUC

The images show our design proposals for a shade roof on the central square in the university campus of the German University in Cairo to optimize the conditions of use there.
The space is primarily used for catering for students and employees. It is a popular meeting place and location for meetings and presentations. Current information about university operations runs on the large screen. Due to the climatic conditions, it is often not possible to use the food court during the day, especially in summer, as the temperatures are too high and people therefore tend to seek out closed rooms or the shade. It was against this background that the project to build a shade roof came about.
The following goals are associated with this:
• Improvement of the heat situation during the day through shading (shade roof)
• Enabling use in the evening by illuminating the square from the shade roof
• Increase appeal – more guests use the food court
• Increased length of stay – guests stay longer
Our work consisted of the architectural concept for a large-scale roofing in several variants. By Ruairí O'Brien. For this purpose, a suitable lighting concept was developed for the attractive staging of the room below.

Eternity Art Competition Frechen Central Memorial

Eternity

Competition entry by Ruairí O’Brien for the Frechen Central Memorial

Ruairí O'Brien's work of art "Eternity", with its striking and at the same time simple elements in a material and metaphorical sense, forms a dignified space for remembering all victims of the National Socialist tyranny. The two vertical masts and the line of light floating horizontally between them mark and house the real Fre¬chen green space; At the same time, through the immaterial spaces in between, they inspire an unlimited mental wandering between times, spaces and events. A line crosses the sky and illuminates the ground below. At the same time, reference is made to the spatial and temporal significance of the topic. The meta-level created in this way, which can be perceived haptically / visually / with the senses, forms an expansion space and yet an ensemble with the information board designed for concrete, authoritative verbal information about the history. 
“Simplicity gives complexity” - Simplicity allows and harbors great complexity here. 
The work of art brings public attention to the central memorial site. It marks this central square as a central memorial day and night and symbolically refers to the places where the events took place. The work encourages you to linger, to pause, and offers flexible space for mediation work by institutions, groups and individual actors. 
The line of light (bridge) that invites you to look, think and remember, it remains, it is always there.
The work of art has a noticeable day and night effect. Depending on the viewer's location, depending on the time of year and day, depending on the weather, lighting conditions, environment and individual visitor's condition, it develops its effect - sometimes more delicate, sometimes more intense, always with a long-distance and close-up effect.
Anyone who approaches the work of art opens up different perspectives and perceptions. Viewers are reflected in the masts, their gaze connecting their own self with the surroundings and the subject matter. The environment is reflected in it, light is reflected and directed.
