Researcher’s guideline to human-centric library lighting
How can lighting be used to create different activity zones that meet the visitors’ needs and enhances the experience in the library? In a new master’s thesis from Aalborg University Copenhagen, Maja Munksgaard Danborg and Mariliis Kundla put a spotlight on an overlooked working environment.
The purpose of Maja Munksgaard Danborg and Mariliis Kundla’s thesis was to create a better understanding of the different functions in libraries and how comfortable and inviting lighting can be used to enhance the feeling of personal space. In close collaboration with the community library in the Swedish town of Falkenberg, they have identified four inspiring activity zones for the contemporary library.
The Evolving Library
The digital revolution has made the library a dynamic place of creating and exchanging information, not merely a place of storage and retrieving. ”A library has been, and will continue to be, a rather private, focused and quiet place and we don’t think the development has brought that many changes to the library setting per se. But of course, electronic means of communication need a different lighting approach, for example being aware of the direction of the light source in order to avoid glare on the screens and the need of more power sockets in the room. Nonetheless, the expectations for the quiet, library mentality stays the same. It doesn’t matter if you are researching by going through a pile of books or on the laptop”, says Mariliis Kundla.
However, the 21st century library has evolved into more of a cultural house, expanding with the activities available in the library. This brings the general well-being of the visitors into focus, as modern libraries need to be more adaptable and conscious of the lighting, as well as other health affecting factors. The expansion of the many different activities and variety of visitors of many ages and backgrounds forces the new library spaces to take on an extensive change. From a lighting perspective, it is important to move forward from the trend of lighting the space up in a uniform manner, Mariliis muses:
”Or as Traci Engel Lesneski, Chairman of The Inter Federation of Library Associations and Institutions, puts it: ‘Lighting for the task is key: simply flooding library buildings in a one-size-fits-all approach of even lighting is no longer acceptable.’ The more personalised approach to lighting also means more sustainability – being smarter with the daylight usage, using sensors and smaller light sources has a lot of potential for more efficient energy usage.“
"The more personalised approach to lighting also means more sustainability." Mariiliis Kundla, Lighting designer/audio-visual producer at Vertigo ApS in Copenhagen
Four activity zones
Planning to build a new library in Falkenberg, the Region of Halland was interested in finding out how human-centric lighting can be used to attract and keep visitors, offering the existing library as a research object. As part of their investigation, Danborg and Kundla have made interviews, conducted investigations and tests in a close dialogue with the librarians. Results can be used as a platform when planning the new library building.
”Our idea was to create different activity zones for different purposes, experiences and functions within the library space; the work zone, the play zone, the cave zone and the chat zone. This would allow the visitors to find a more personal space and still be able to coexist with each other while performing different tasks”, Maja explains.
The zones were formed after visiting different libraries and observing the behaviour of the visitors, finding that every zone did not appeal to all users. For example, you would not normally see children or elders using the work zone, were the study area, computers and reading tables were located.

Successful Tests
To support the lighting solutions of the zones, two different lighting tests were conducted. One lab test in the Light Lab of Aalborg University and one field test at the library in Falkenberg, both tests using Fagerhult fixtures. The main goal of the lab test was to find out the preference of correlated colour temperature of different age groups – children, young adults, adults, elderly – for ambient and task light in all four activity zones.
”For the field test, we created four light presets for every activity zone with the purpose to investigate the visitor’s preferences. The settings included the four activity zones with furniture, a Samsung tablet with Casambi application and four fixed light presets, and a total of 15 Fagerhult Marathon White Tunable fixtures”, Maja explains: ”
We found out that the overall most liked preset was ‘play preset’ meaning that the 3600 Kelvin lighting in both ambient and focus light was preferred, creating a golden medium. Concluding that if you don’t know what type of activity zone you are creating the middle ground 3500-4000 Kelvin will be preferred by most people and then the intensity and direction of the spot create the right feeling inside the space. Though, it is important to state that these zones cannot be created only with lighting. You need to work with all tools in the interior toolbox, like furniture, colour and textures to create the right experience within a zone.”
Holistic Approach
Maja and Mariliis hope that their research will contribute to more holistic lighting process.
”Implementing the lighting design into the earlier steps of the whole architectural process is essential. Currently, the focus is mostly on the amount and direction of natural daylight, while electric light has been secondary, coming into play later, often with quantity over quality. We’re hoping for somewhat of a revolution in this scene, with the LED technology becoming more easily approachable and people’s holistic needs more into focus”, says Mariliis: ”Our objective was to provide guidelines that have value both when constructing new libraries or cultural houses as well as when improving existing libraries.
As the four zones are already present in the existing libraries, the application could just be a matter of slight furniture reassignment and, of course, applying the light fixtures of correct positioning, CCT and brightness.” They believe that human-centered design is essential when discussing future libraries and public spaces in general. Libraries are evolving into more dynamic multifunctional cultural houses that need to be in sync with the constant flow of the wide visitor basis and their needs.
”There are and will be many different activities available in the future library: from studying, eating, resting and meeting friends to 3D printing, getting citizen advice, applying for a job or attending a lecture. Therefore, with the expansion of the physical spaces as well as the people flow and functions, meeting visitors’ needs has become more challenging but also more into focus, demanding for a more holistic experience of the library environment.”
The four activity zones of the contemporary library
1. Work zone
This is the zone were mostly young adults and adults are seen; a lot of students are using the library to study in groups or alone. The work zone has several different functions such as study areas, group work areas, reading tables and laptop/screen areas. The experience of this zone should be similar to an office environment and create feelings of focus, calm and inspiration.
2. Cave zone
This is the zone where the visitors can engage in relaxing functions and be by themselves, listen to music, read or just spend time. The cave zone is a relaxing space where you can create your personal bubble without being interrupted by noise or other visitors. This zone can be used by visitor groups and should generate feelings of comfort, safety and privacy.
3. Play zone
This is a more playful zone with children's area, youth and gaming section. This environment should spark inspiration and enhance feelings of playfulness, curiosity and innovation.
4. Chat zone
This is the zone where visitors can sit down and chat, for example a lounge area. This area should inspire people to talk freely and relax with others and the interior and lighting should create feelings of comfort and privacy.

Melanopic lux: lighting for education influenced by human biology
Light is essential in our daily lives, influencing our ability to see, overall well-being and performance. In educational environments, lighting quality can significantly impact students' focus, mood, and energy levels. So, how do we know what is the right amount and quality of light for this setting? Traditionally, light has been measured in lux, a unit of measurement for the intensity of light. It's used to measure how much light falls on a surface or the amount of light in a given space. One lux is the amount of light that falls on a surface that is one square meter in area when one lumen of light is spread out evenly. Recent advancements in research have unveiled the importance of melanopic lux, which goes beyond mere visibility. This measures how effectively light stimulates specific eye cells that regulate crucial non-visual functions such as sleep and alertness. In classrooms and lecture theatres, the melanopic ratio has become vital in lighting design, enabling educators to create spaces that support visual tasks and align with students' biological rhythms. In this article, we explore how lighting solutions can align with our biology, and how this helps to create optimum conditions for educational environments. The science of vision and light The human eye is a remarkable organ designed for high-resolution colour vision within a small area (approximately 2 degrees of the visual field) while relying on peripheral vision for motion detection. This dual-function system, shaped by evolution for survival, continues to influence how we perceive and interact with our surroundings. Our eyes are particularly susceptible to green and yellow light, reflecting our evolutionary adaptation to naturally lit environments. In contrast, blue light, which is chief in modern LED lighting, requires higher intensity to be perceived at the same level. Effective lighting design carefully considers brightness, timing, and distribution to support visual clarity and biological functions like mood and alertness. For example, exposure to bright light in the morning helps regulate circadian rhythms, boosting alertness and mitigating the effects of seasonal darkness. This is particularly important in educational environments, such as schools and universities, where lighting impacts mood, focus, and overall performance. Our Organic Response system provides an innovative solution tailored for these spaces. This smart lighting technology automatically optimises light levels, featuring daylight-responsive sensors and advanced occupancy detection, maintaining a balance between natural and artificial light. Doing so supports visual comfort and reduces energy consumption, making it an ideal choice for creating dynamic, efficient, and student-friendly learning environments. To further support students, well-lit spaces with minimal glare are essential for reducing eye strain and maintaining focus during extended study sessions. Adjusting light intensity and colour temperature for different tasks—such as reading, group discussions, or creative activities—enhances light's visual and non-visual effects. By integrating thoughtful lighting strategies like those offered by Organic Response, educational environments can promote healthier, more productive, and engaging learning experiences. Integrative lighting: Supporting health and well-being. Integrative lighting (also referred to as human-centred lighting) combines visual and non-visual benefits (such as emotional effects) to support biological rhythms and psychological well-being. This approach goes beyond traditional lighting solutions by considering how light impacts circadian rhythms and hormonal balance. Light exposure in the morning is critical for suppressing melatonin (the sleep hormone) and increasing cortisol (the alertness hormone). Proper timing helps align students' natural rhythms with school schedules, which often require a lot of focus. Consistent exposure to bright, cool light early in the day can enhance energy levels and cognitive performance. The melanopic ratio compares the spectral composition of a light source with daylight. Using this information, you can determine its melanopic lighting intensity. This enables the design of lighting setups that precisely meet both visual and biological lighting needs. Lighting recommendations for educational spaces Each learning environment has unique lighting needs. Libraries benefit from direct lighting on the floor, paired with ambient lighting on walls and ceilings. Vertical shelf lighting (200-300 lx) makes it easier to browse titles. Lecture halls, on the other hand, require glare-free, comfortable lighting with flexible control, ideally with pre-programmed scenarios. In auditoriums and classrooms, strong vertical lighting is crucial for clear visual communication, especially over greater distances, enhancing facial expressions and engagement. General lighting recommendations apply to all educational spaces. Our solutions meet industry standards, ensuring reading and writing areas maintain 500 lx for effective visual tasks. Using daylight-responsive sensors for luminaire rows can reduce energy consumption while maximising natural light. The number and arrangement of luminaires should be adjusted based on the room's size and function to ensure consistent illumination. The role of dynamic lighting A Double Dynamic lighting system can be a game-changer in educational environments. It allows for intensity and colour temperature adjustments to match the specific needs of activities, from quiet reading sessions to collaborative group work. Fagerhult's distinct approach to lighting means that our design is human-centric; we integrate scientific insight into light and human psychology, creating environments that support academic performance and well-being. Our focus on energy efficiency also means our advanced control systems optimise light usage while minimising energy consumption, contributing to a building’s sustainability goals. The customisable setting and flexible solutions ensure that educational environments can create tailored lighting profiles for different times of the day or specific learning activities. Long-term benefits of melanopic lighting Melanopic lighting, designed to mimic the natural light spectrum, helps regulate the circadian rhythm, which is essential for maintaining focus, energy, and emotional balance. In classrooms and study areas, proper lighting can reduce eye strain, improve sleep patterns, and enhance mood, which are critical for students' mental health and academic performance. By incorporating lighting that aligns with our biological needs, schools and universities can foster healthier, more productive learning environments,. This is particularly important during the winter months when daylight is limited. Whether through advanced tuneable white light systems, designs that maximise daylight, or energy-efficient solutions, we are dedicated to leading the way in lighting innovation for educational environments, delivering brighter futures—one classroom at a time.
The inspiration behind Nobel Week Lights: ”Light, art and technology intertwined.”
Nobel Week Lights has quickly become a beloved public celebration. During Nobel Week, Stockholm residents flock outdoors to marvel at the spectacular light installations, where contemporary lighting technology meets artistic expression. ”We aim to create a moment of gathering: around light and around something meaningful”, says Lara Szabo Greisman. Nobel Week Lights is a light festival that illuminates Stockholm during the darkest time of the year – a free cultural experience for everyone. Presented by the Nobel Prize Museum, the festival invites international and local artists, designers and students to create light artworks inspired by the Nobel Prize. The installations shed new light on the scientific discoveries, literature and peace efforts of Nobel laureates while offering a fresh perspective on the city. Fagerhult is Principal Partner of Nobel Week Lights 2024, and this year’s edition features 16 different light installations across Stockholm. The artworks can be experienced from 7–15 December, including ”The Wave”, a light installation by the art collective Vertigo, located in front of the Parliament House where visitors can walk right through the luminous wave. The Wave by Vertigo ”Light and art and creativity is incredibly intertwined because these are technologies that are constantly evolving. So part of the fun working with the artists is that they are constantly testing new technologies. And we see these incredible visual results which are based on just pure innovation”, says Lara Szabo Greisman, co-founder and producer of Nobel Week Lights. Lara Lara Szabo Greisman and Leading Lights by Les Ateliers BK The significance of light as a collective force, its ability to encapsulate life and death, joy and sorrow – indeed, the very essence of what it means to be human – makes lighting a powerful medium of artistic expression, she argues: ”The dream for the festival is that this becomes a personal experience for each and every member of the audience. A moment that they remember and cherish . A moment that they think about later and bring forward as their story of connecting with the city.”
