From Science to Practice: Implementing Evidence-Based Holistic Lighting in Architectural Lighting Design
No full textDespite decades of research on light’s non-visual effects, lighting design practice remains largely focused on visual metrics and energy codes. Designers lack accessible tools to integrate biological principles into architectural workflows. This thesis introduces a framework for HOLISTIC LIGHTING DESIGN through the Biological Lighting Protocol. This three-step strategy evolves from defining circadian needs to targeting appropriate spectral qualities before concluding with a light strategy and spatial narrative. Developed by the author through a design translation methodology and shaped by her professional practice background, the protocol enables practitioners to apply metrics such as CS and M-EDI without specific expertise in neuroscience, biology, or mathematics. Its validity is supported by leading scientific studies, expert recommendations, and the author’s own applied experience—offering a practical, health-oriented approach that reframes light as a biological interface within spatial design
Biophilic Dynamic Light Projections: A proposal for the revitalization of socially-inactive urban spaces
No full textThe notion of “biophilia” refers to our innate and genetically determined affinity to nature. Despite having numerous benefits on our well-being and on how we perceive our environments, facts proven by a significant amount of scientific research, biophilia in the sphere of lighting design is a relatively untapped niche. Therefore, this thesis seeks to investigate the combination of biophilic patterns with modern technology with the intention to implement them in socially-inactive urban spaces as a mean of fast and effective revitalization. The overall goal is to establish new knowledge on creating, implementing and fine-tuning biophilic dynamic light projections. Through an extensive literature & case study review, design experimentation and atmosphere perception test, valuable knowledge on the notions of “preference for biophilic patterns”, “visual complexity”, “speed of change” and “value-add of interactivity” was developed. It is concluded that biophilic patterns are more positively perceived than their non-biophilic counterparts. Moreover, overall preference for complexity lies at a low to medium degree, while with speed of change, it is overall determined that a low value is inherently more pleasant, with negative consequences on the perception of atmosphere if increased. Additionally, adding the possibility to interact with the biophilic pattern provides overall better perception of safety and atmosphere. On the creation of patterns, the author recommends solutions based on the size of the space: with video projectors and the software Processing as ideal for small-scale implementation, while gobo projectors are recommended for large-scale projects

A Matter of Position: How luminaire placement modulates the perceptual and neural impact of LED flicker: An EEG Study on Flicker Perception and Cognitive Load
No full textThe general adoption of energy-efficient LEDs has introduced non-visual challenges such as flicker. Often, as a by-product of lower-quality drivers. While typically flicker is seen as a nuisance, this thesis aims to explore the impact of flicker through the lens of a lighting designer, asking the main research question: Does the negative impact of a flickering luminaire change depending on where you position it?To see whether there is a correlation between position and frequency, a 2x2 experiment design was set out. It tested a low (60Hz) and a high (200Hz) frequency, with the luminaire being either positioned as general overhead lighting or as task lighting in the participant’s peripheral visual field. Subjective data were gathered through questionnaires, as well as objective data were measured with an EEG. Fifteen participants performed a card-sorting task under the four lighting scenarios. The results show that, subjectively, 60 Hz lighting was most disturbing, especially in the task lighting position. However, these subjective measures were not reflected in the objective Gamma Bandpower. Indicating that the participants might have felt like it was disturbing, their physiology did not reflect that. This shows the disparity between perceived experience and our physiology. The research concludes that, as a lighting designer, when creating a human-centred design, we should look beyond our measures; in the end, the user’s feeling of discomfort is the ultimate benchmark. It also strongly suggests that any luminaire with potentially noticeable flicker should be kept out of the peripheral visual field
Light as a form of visual language in educational spaces : Creating schedules for daily activities
No full textExplore methods for digital asset reconstruction and their application within lighting design
No full textThe following paper explores the topic of image capturing and digital reconstruction method known as photogrammetry. More specifically it focuses on the application of this method in the field of lighting design and aims to provide an in-depth descriptive account of different techniques and approaches of doing photogrammetry, and challenges that arise from them. The paper consists of multiple use cases, which help illustrate different aspects of the photogrammetry process, covering areas such as: image capturing strategies, de-lighting techniques, and digital workflows. It later transition into a discussion of automation and the advantages it can offer for the development of this particular field, and proposes a prototype design for an automated photogrammetry platform
The Influence of Colored Lighting on Navigational Decision-Making in Virtual Environments
No full textThis study investigates how colored lighting influences navigational decision-making in virtual environments, with a focus on player preference among red, green, and blue illumination. Utilizing both an online and an in-person experimental setup, participants were asked to select between visually identical corridors, each lit with a different color, under both exploratory and time-pressured conditions. Quantitative data revealed a consistent preference for green lighting, particularly in the online version, while the in-person setting saw increased selection of blue under immersive conditions. Red lighting was the least preferred in both contexts. Age showed weak correlations with color preference, and no statistically significant gender differences were observed. Qualitative feedback highlighted the role of intuition and emotional association in guiding choices, particularly under stress. These findings suggest that color serves not only an aesthetic or atmospheric function in virtual design but also acts as a subconscious cue for spatial behavior. Implications for game design include using color strategically to guide player movement, evoke emotional responses, and adapt environmental cues to game play context. The results also suggest possible applications in real-world architectural lighting and interface design where intuitive navigation is critical
