Museum of Light

Designing a Light Museum was an exciting and fulfilling topic for the students. It allowed them to explore the inspiring relationship between light and science, art, technology, and architecture while reflecting on their Egyptian heritage. The project’s location on a peninsula near the monuments of Abu Simbel, which celebrate sunlight during the winter and spring solstices, made it an even more fitting endeavor.

Light, a universal topic with transcultural significance, touches on profound subjects like poetry and philosophy as well as pragmatic concerns like energy, health, and economics. There are very few true “Light Museums” in the world. Most often, technical or science museums cover this topic, or art museums showcase artists’ interpretations of light. However, no museum or institute tells the story of light in all its consequences and expressions through a holistic experiential concept from building to exhibition. Abu Simbel, with its historical and mythological links to the power of light and its dam generating the country’s electricity, is an ideal location.

The question arises: can we construct a new building in such a historical context? My answer is unequivocally yes, but it leads to a finer question: should the new building be visible or hidden? This is a common challenge for architects working in historical contexts. The students’ excellent answers to this are showcased in the exhibition.

The project aimed to raise awareness among the students about the economic and social benefits that first-class contemporary architecture can bring to local communities. Long-term sustainability involves providing opportunities for people to thrive, encouraging local businesses to grow, and attracting outside investments. The project also included a Life Long Learning Institute, where visiting researchers and artists working with light could engage with local people, children, and youth projects. This is how architecture can extend its program to support regional development, providing a space for education, knowledge, tourism, business, and human exchange.

The bravery of repositioning the monuments to construct the Aswan Dam set a precedent for extending the story with a new visionary attraction of contemporary architecture, linked to Egypt’s ancient and modern history.

The bachelor project is the highlight for the students, marking the end of a long and sometimes stressful period of study. The rewarding feeling of deep achievement follows and cannot be taken away. Congratulations to all students for their enthusiastic work, and special thanks to my teaching assistants for their support this year, Abdelrahman Ghoneim and Marian Ghali.

“House of Architecture” Cairo in Light

Photo shooting of my Lighting Design Elective students final installation at the „House of Architecture“ last night in Islamic Cairo …
Thank you all at the House of Architecture“ and Director Prof. Heba Eldeen for your support and allowing us to use the location to work with …

The House of Architecture in Islamic Cairo area of Darb Al Labana is a wonderful example of vernacular architecture and climate control design. It is fascinating to experience how the compact stone building with “Mashrabiya”, Light wells, courtyards with water pools controls and distributes daylight and natural ventilation to achieve a micro climatical world of quiet comfort in the megapolis.
The house offered the students a diversity of small and big spaces to try out different lighting scenarios.

Thank you students for the concentrated work through out the semester, a small exhibition is coming!
And of course thank you TA Mai Tarek…


Light painting technique

Have you ever thought about the technique of light painting? Is it possible? And how do they do that? To find out, don’t miss the opportunity to attend the “Light Line” workshop with engineer Ruairi O’Brien, a workshop that combines Arabic calligraphy and light painting. Ruairi O’Brien is an architect, lighting designer, artist and teacher. He is an associate professor and head of the Department of Architecture and Visual Design at the German University in Cairo and founder and director of the Eric Castner Museum in Dresden, Germany. He has exhibited his artwork, lighting projects and architectural works internationally in several cities including Cairo, Berlin, London, Tokyo, Frankfurt, Leipzig, Dresden and Washington.



In collaboration between the GUC Cairo and the Swiss Club Cairo and on behalf of the SCC board, an award ceremony for 11 final projects of the GUC students took place on January 31, 2024. The redesign of the green oasis now creates an active open-air zone in the club’s unique historic city garden, accompanying an attractive, modern approach to cross-generational activities, interesting outdoor experiences and an adaptable space for various occasions.

The House of Sustainability

Tharandt Saxony (2014)

The town of Tharandt has the oldest academy of forestry in Germany, founded as the Royal Saxon Academy of Forestry by Heinrich Cotta in 1811 together with its arboretum, the Forstbotanischer Garten Tharandt. Today the Academy educates students from all over the world in (tropical) forestry, resource management and sustainable land use.

The design for a „House of Sustainability„ is part of a larger architectural feasibility study we undertook for the forest town of Tharandt.
Our work included conceiving and organizing a series of citizen participation meetings and surveys as to how the town could develop its potential as an important international tourist attraction and simultaneously increase the attractiveness for the locals.

One of the main focuses of our work was to suggest an appropriate use for the prominent site of the destroyed „German House„ (the towns former cultural hall and cinema).
This site is situated on the main approach road from Dresden and can be seen as being an important „Welcome Sign“ and expression of the „Spirit and Identity“ of the famous „Forest Town“ for visitors and citizens.

The „House of Sustainability“ concept was to provide a forum space and „Info Center“ for local participation in climate change topics and an exhibition about „sustainability and holistic thinking“. The construction was in timber and could be used as a winter garden by citizens on a daily basis.

After my recent participation in the COP28 in Dubai I think that we need to establish a series of „Sustainability Info Centers“ in all cities and towns to communicate the importance of people participation in climate change issues and to educate / inform in a dialog school kids and youth.



Nachhaltige Strategien in Architektur und Stadtplanung


D-Gebäude D4.02 Zweiter Stock Deutsche Universität in Kairo

„Contemporary Heritage“ ist eine nachhaltige Smart-City-Strategie, da es bei Smart Cities nicht nur um technologischen Fortschritt und Effizienz geht; Sie umfassen auch die Erhaltung des kulturellen Erbes.

Denkmalgeschützte Gebäude bewahren das kollektive Gedächtnis und die Identität einer Stadt und bieten eine Verbindung zu ihrer Geschichte. Durch die Integration dieser Strukturen in Smart-City-Initiativen wird sichergestellt, dass die moderne Stadtentwicklung die Vergangenheit respektiert und den Bürgern Narrative über neue Entwicklungen bietet, auf denen sie aufbauen können.

Dieser Ansatz bewahrt nicht nur den einzigartigen Charakter einer Stadt, sondern fördert auch die Nachhaltigkeit durch die Umnutzung vorhandener Ressourcen, die Reduzierung des Bedarfs an Neubauten und die Förderung eines Gefühls der Kontinuität und Zugehörigkeit unter den Stadtbewohnern.

Auf diese Weise schützen intelligente Städte historische Gebäude als wichtige Bestandteile einer ausgewogenen, zukunftsorientierten Stadtlandschaft.

Die „Mikroimplantationen“ neuer Bausubstanz und die Einfügung neuer Nutzungsmöglichkeiten in Denkmalschutzgebieten fördern neue wirtschaftliche Entwicklungen und soziale Interaktion.


Article about Microarchitecture published

Architects and Lighting designers can learn from studying the human body to improve buildings and cities.

In 1999 I was asked by the Hygiene Museum in Dresden to work on a concept to present the “Gläserner Mensch” (Glass Human) and the “Virtual Mensch” in a new permanent exhibition they were planning.

The “Gläserner Mensch”, a transparent life size model of a human figure which enabled the viewer to see the inner workings of the human body through a transparent outer skin, was first shown to the public at the 2nd International Hygiene Exhibition in Dresden, Germany in 1930, the first International Hygiene Exhibition was in 1911. The Hygiene museum was founded in 1912 by Karl August Lingner, a Dresden manufacturer of hygiene products, as a permanent public venue for healthcare education. It must have been a spectacular event, entering the darkened space to see a silhouette of fellow visitors standing around the glowing figure, organs, heart and veins, lighting up from within at the touch of a button, a further milestone in humankinds desire to depict and understand the wonder of the human body, a marriage of Leonardo da Vinci’s anatomy drawings, his Vitruvian Man (1490), Michelangelo’s marble stone David (1504) and Fritz Lang’s Maria from Metropolis (1927).



Exploring, Celebrating, Re-Vitalizing and Protecting Heritage Architecture ad Cities withi New “micro-architecture input”

… in this Years bachelor studio of Ruairí O’Brien at the German University in Cairo.

The importance of HERITAGE Protection in Cairo is undisputable.
But how do we Protect Heritage?
This question is hotly debated worldwide.
What role does the Vernacular play in this?

To enrich the debate, we are delighted that Professor Ahmad Hamid, Author of “The Birth of a New Modern – Hassan Fathy and Continuity in Islamic Arts and Architecture” will present his thoughts on this matter to my students currently working on their bachelor project in the historic Darb Al-Labana area of Islamic Cairo.


3 X 3


3×3 – Three experts talk on 3 interrelated topics and how they work together to create the ARCHITECTURE and the BUILT ENVIRONMENT we live, work and play in. The event will give insight as to how LIGHT and COLOR can be used to create exciting human responsive SPACES.

“Soundless Music” – Lichtkultur sehen und verstehen

Lecture by Ruairí O’Brien at the Licht2023 in Salzburg

Developing an understanding and awareness for what constitutes good quality lighting among architects, urban planners, politicians, decision makers and most importantly the users of our built environment, requires greater enlightenment and energetic input from the lighting design profession. In this lecture using examples from my work, I discuss “seeing and understanding” the role lighting design could play in establishing a future “Licht-Baukultur” in our built environment.

25th European Lighting Technology Congress, March 26-29, 2023, Salzburg / Austria

Lighting concept for Bad Vilbel

We are pleased that our contribution in the selection process for a lighting concept for the historic center of the well-known mineral water / spring city Bad Vilbel has been awarded the Zuschlg.

The spring city BAD VILBEL is located in the south of the federal state of Hesse, in the immediate vicinity of the metropolis Frankfurt am Main.
The focus is on the inner city area with the main shopping street Frankfurter Straße, the river bank, the adjacent spa park areas, the festival grounds with the Burgpark and the connections from the inner city to the railroad stations (Bad Vilbel and Bad Vilbel Süd), which together form the historical and social heart of Bad Vilbel.

As part of the nationwide “Living Centers” program, this urban core area is to be upgraded with a new and innovative lighting concept.

We are pleased to be able to develop a lighting concept for Bad Vilbel with the following contents:

  • An attractive, innovative and sustainable lighting concept to improve the evening ambience.
  • Staging of the historical building fabric in the appropriate architectural lighting scenarios.
  • Improvement of the citizens’ sense of security at night.
  • Developing temporary lighting concepts for special events, holidays and celebrations.

This wonderful project will accompany us through the year 2023 and in this spirit I wish all friends and colleagues a happy, healthy and successful year 2023.


Alte Baumwolle Flöha

Light concept old cotton Flöha

“City Lighthouses” concept wins award.

Competition Award for Lighting Design Concept to “Re-Animate” the Heritage protected city “Cotton Mills” area of the city of Floha in Saxony, Germany.

“Re-thinking the Inner City and heritage”

“Flöha receives award in the competition “Ab in the Mitte! The City Offensive Saxony” 2022

Under the motto “Creatively out of the crisis – rethinking the inner city”, 34 project ideas for revitalizing inner cities were submitted by 33 municipalities.

The award ceremony took place as part of the Heritage trade fair in Leipzig on November 25, 2022.

“Ruairí O’Brien . Lighting Design” developed a lighting design concept for the old cotton industrial buildings in the city of Flöha.

This is part of a bigger development to develop the new city center in the old cotton mills which will include the new market place, urban landscaping and dynamic lighting.

Head of Building Authority, in The City of Floha, Andre Stefan accepted the congratulations and the certificate from State Secretary Thomas Kralinski (SMWA).

Flöha’s project idea is to install interior lighting of the three towers on the “Heritage building” with dynamic resource-saving LED lights.

It is intended to be the first building block for the implementation of accent lighting and to contribute to making the cubature of the largest building complex in the Old Cotton area appear in the early evening hours in a timely and sustainable controlled manner.

It will “attract” life into the future city center, support businesses and tourism in their development and increase the experiential quality of the citizens and visitors.

“The “Cotton Mills” area in Floha is an important example of the wealth and identity of Saxony’s innovative industrial History. We need to put the historical richness of such towns and regions in the “Light” to ensure their future and development. That is the idea behind “Lighthouses” for Floha”

Ruairi O’Brien.

Below is one of our visualizations used for the competition entry “Light Towers” of the city of Flöha 2022.


Concentration Camp Mittelbau-Dora, Nordhausen

Pleased to announce:

3rd place for “Ruairi O’Brien Architects” in Competition for ”Memorial and Exhibition architecture – Concentration Camp Mittelbau-Dora Nordhausen”, Germany.

The Competition called for a re-working of the existing permanent exhibition, and the development of an extension of the exhibition into further areas of the tunnel system built underground close to Nordhausen by the N.S. Regime during WWII to manufacture the infamous V-2 rockets.

Entrants were required to deliver a new pedagogic/didactic concept for the contents of the exhibition, the exhibition and presentation architecture, barrier free access solutions and a lighting concept. We are pleased that our “points and lines” concept was successful and awarded the third prize in such a sensitive and complex competition with numerous renowned participants.

Energy saving can be “designed”!

Cities are “the place to be” and deserve good LIGHT.

The revitalization/development of city centers needs LIGHT, it is a question of quality and not quantity.

Cities and buildings need better and more intelligent lighting concepts …

We should try to protect and promote sustainable “City LIFE” by using the current debate about energy waste to rethink the quality of lighting in our cities.

Light attracts and creates moods for interaction and exchange, our cities need to be attractive to be (economically) sustainable.

“See more with less light” and enjoy city life – this is possible with holistic creative concepts and dynamic intelligent lighting technology. Achieving the right balance of light and dark in cities is first and foremost a creative task. Energy saving can be “designed”!

First, ask a lighting designer….

This is a call to urban planners, politicians, decision makers, offices and citizens to take the chance to discuss openly with lighting designers about “LIGHT CULTURE” and energy, the culture of good and sustainable light in our cities and towns.

The drawing is from a lighting concept for the revitalization of an unused industrial building, ” Spinnereimaschinenbau” in the city of Chemnitz, Germany (2018).


The DAY of natural LIGHT

Today, June 21, 2022, is the summer solstice and thus the longest day of the year in the northern hemisphere of the earth. On the occasion of this event, we would like to celebrate the light of day, which is usually taken for granted, and point out its great importance in architecture and lighting design. In our planning, we work specifically with the natural light of the sun and integrate daylight into our projects both functionally and creatively. Because daylight is fascinating, constantly changing in its intensity and color.


& Immersive Installations “DAY and “NIGHT”

Today the first-year Visual design students will be finishing their semester with a special one-off experience, a final “Happening” to round up the last two semesters we have spent together.

The term “Happening” is broadly used in the art scene to describe a moment in time (and space) were we heighten the experience of our senses and of life by choosing to meet, to engage, to do something together, to observe or participate in an action, to be there in the moment, to allow a moment be special.

More information can found here.


Light Machines:

Today is the last chance to visit the exhibition of “Light Machines” made by my lighting design students at the German University in Cairo.

The “Light Machine” project is a teaching concept I first developed and introduced to the lighting design masters program in the university of Wismar, Germany 20 years ago and I am fascinated to see how robust it is in absorbing the dynamic process of changing technologies.

The project challenges the student to develop and make a kinetic sculptural object that can be used to demonstrate the principles and inherent characteristics of light (+ technology) and the interaction of light with space, materials and humans.
It is Beautiful, Educational, Science and Art.



Thank you Habiba Walid for making a great poster for our “Light, Color and Materials” exhibition on the 07.06. @ the German University in Cairo.
The students work is looking good, drop by and have a look…!


International Day of Light

Today we celebrate the Unesco international Day of Light, as every year since 2018.

Among other things, it aims to raise awareness of the role that lighting design and the targeted use of technologies play in achieving greater energy efficiency or limiting energy waste and reducing light pollution, which is also key to maintaining the visibility of the night sky.

International Day of Light is held on May 16, the anniversary of the first successful use of the laser, in 1960, by physicist and engineer Theodore Maiman. The laser demonstrates how a scientific discovery can bring revolutionary benefits to society. It is celebrated with many different events around the world, where all participants can develop an understanding of the role of light in science and culture.

More information can be found here.


Installation works New Work – lighting concept

Photos of our office extension project, which is close to completion, from the joint inspection with the management of the future user. We accompany this project not only architecturally, but also with a lighting concept for modern working environments of today, tailored to the individual requirements of each area. In the next few days, the installation of the luminaires will be completed, but there is still some work to be done before the object can be handed over to our client in the fall.

We are looking forward the newly created space being used and offering our client a workplace where people like to stay and work well.


International Dark Sky Week – April 22 – 30, 2022

For us as lighting designers, the protection of darkness and thus a responsible use of light is very important. In lighting design, the motto is: Less is more. That’s why we support this year’s “International Dark Sky Week” to draw attention to the problems that light pollution causes. Light pollution can disturb wildlife, affect human health, waste money and energy, contribute to climate change, and block our view of the universe.

So get informed about light pollution and support International Dark Sky Week.


Unterwegs im Licht 2022, Freitag

Since last Friday, until tonight, our urban “Soundless Music” light composition for Potsdam Unterwegs im Licht 2022 is running. The photo shows Potsdam’s Nikolaikirche in a blue dress of winter light, with which our composition started on Friday evening. Over spring-like green light moods on Saturday and summer-like yellow-orange light scenes on Sunday, the four days of Unterwegs im Licht 2022 end today with a thoughtful backdrop of dark red tones, which are accompanied by light moods from ALL MAIN COLORS of the color spectrum for the FINALE at 9 pm.

Daylight design in architecture

For this year’s first Design Studio at the German University in Cairo, Ruairí O’Brien worked with his students on the importance of daylight in housing.

LIGHT is an energy, life and mood-giving force in architecture.
The special properties of the morning, midday and evening sun can be used to model and shape the architectural volume (the importance of northern light). Light can be used to shape walls, position openings, and form roofs.

For example, energy conservation also begins with providing excellent daylight to building occupants and reducing the need for artificial lighting. Understanding how light and shading can be used to create thermal comfort for occupants is critical to building success.

The architecture of light is about beauty and the intelligent use of resources.
Daylight can be used for free and its tremendous value is widely underestimated in the building industry. Architectural design begins with an understanding of this resource.

Ruairí O’Brien, Architekt und Lichtdesigner

“Die Lichtdesigner Community ruft im Allgemeinen und was den Klimaschutz anbelangt, den Kampf für die gute Sache (Licht) auf. Wenn der Kunde es aber möchte und dafür bezahlt, machen wir vor allem schönes Licht, wir beleuchten – unabhängig von den Kosten für die Umwelt, die Architektur oder den öffentlichen Raum, die wir ausleuchten. Sind wir als Community damit im Reinen? Oder ist es uns einfach nicht so wichtig?” Ruairí O’Brien

“The lighting design community in general and as far as climate protection is concerned, calls the fight for the good cause (light). But if the customer wants it and pays for it, we make beautiful light first and foremost, we illuminate – regardless of the cost to the environment, the architecture or the public space we illuminate. Are we as a community at peace with this? Or is it simply not that important to us?” Ruairí O’Brien
