White Architects is one of the pioneers within BIM projects.
”It all began with the design of the new Karolinska hospital in Stockholm in 2010 – Europe’s most comprehensive hospital project so far. In collaboration with our colleagues at Tengbom Architects, we decided to work with BIM-models to increase the efficiency and quality of the project. In several ways, this project was the origin of the methodology that the industry now applies”, explains Christoffer Sundberg, building engineer and methodology manager specialized in Digital Design and BIM.
”As methodology manager, I focus on how we use digital solutions to ensure quality deliveries to our customers by using BIM models and objects. It’s all about functionality and how different technologies are used to maximize the customer benefit.”
White’s BIM-specialists are part of the company’s Digital Office organization.
The complete story
BIM is an important facilitator of the design process, says Christoffer.
”With BIM, we are able to visualize and work with information and not just geometries. The BIM-models also provide us with important data about size, materials energy consumption, daylight, shadows, GIS-maps and much more. It enables us to connect several disciplines within urban planning to create an incredibly detailed and reliable model that tells the entire story about the building project. For example, the model can provide information on how the new building will affect the green surfaces in the area or the daylight access in adjacent properties.”
At the moment, White often deliver models with more information than the customers require – but according to Christoffer, many customers have realized the possibilities and are constantly increasing their scope of specifications.

Visualization by gaming engines
Of course, lighting and luminaires play and important part in the BIM models created by White.
”We use luminaire BIM-objects to mark placements and to feed the model with practical and aesthetic information about volumes and installations. They also provide us with good information that can be linked to energy supply and consumption. Unfortunately, it’s hard to integrate the lightning calculations and scenarios into the actual BIM-model, but this is something we hope will happen in the near future. Today, renderings of light calculations are very capacity-consuming, but we are actually looking at the possibilities for our lighting designers to use gaming engines to be able to integrate light data into Revit. The game engines, such as Unity and Unreal, have the advantage of working with the graphics card instead of the processor, meaning much faster processing and visualizing”, Christoffer explains.
Open code – a revolution?
In the future, BIM models will have a great impact on how heavy projects are performed.
”We’ve already noticed that the number of physical drawings are decreasing. Instead, contractors choose to work directly with the BIM models. Building sites are equipped with digital BIM-stations with screens allowing construction workers on site to pick up the model and different objects for measuring and verifying the next step in their work.”
The next trend within BIM is accessibility. When a BIM-model can be stored in a cloud and accessed online, everyone involved gets the opportunity to work and see changes in real time.
”There is no limit for what a BIM-model can be or do – the different players of the industry have the power to choose direction. One of the more exciting initiatives right now is Autodesk’s decision to open up their software and launching the platform Forge, enabling other companies to connect their own tools and add-ins It's a great and really confident move that will impact the development in interesting ways!”

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.”
