Conference – During the recently concluded InSpotlight conference at Light + Intelligent Building Middle East 2025, Dr. Amardeep M. Dugar presented a persuasive argument indicating that within the exaggerated claims of the lighting industry, the notion of wellness often amounts to little more than vague aspirations for providing lighting solutions that seek to mimic nature. This includes examples such as color-tunable luminaires, representations of an artificial sky, or photographic depictions of natural environments and light. The myriad instances in lighting design that have employed these clichéd interpretations of nature illustrate that the concept of wellness is frequently stripped of its full potential, akin to an apothecary that exclusively offers aspirin. Dr. Dugar subsequently advocated for a salutogenic approach to lighting. Salutogenesis is a term used to describe a model that examines socio-environmental influences on health and refers to a perspective on wellness that contrasts with pathogenesis, which focuses on diseases and illness. The salutogenic theory essentially asserts that a robust ‘sense of coherence’ is vital to the natural healing process and encompasses three key attributes: comprehensibility, manageability, and meaningfulness. This lecture elucidates how the interplay between health, experience, and performance can be harmonized with lighting design through salutogenic principles and contends that the lighting industry, currently dominated by pathogenic health models, stands to gain significantly from this theory. Consequently, this could enhance procurement processes—typically conservative in nature and influenced by established precedents and standards—as well as shaped by stakeholder groups primarily concerned with cost savings—to give greater consideration to health-related aspects of lighting. Frequently, stakeholders lack adequate knowledge or fail to recognize how aesthetics may impact health outcomes. In scenarios characterized by stringent deadlines, limited spaces, and profit-driven project managers, users are increasingly beginning to appreciate how salutogenic values can enhance their performance. As a result, stakeholders who typically prioritize maintaining the status quo may start contemplating the genuine benefits associated with change. However, it remains uncertain whether lighting designers will possess the resolve to transcend conventional ‘views of nature’ tropes. #lightingdesign #wellness #salutogenesis

Research Publication Journal: Journal of Building Engineering Manuscript Title: Investigating perforated egg crates as dynamic shading systems for open-plan offices in tropical climates Article Type: Original Research Authors: Silvia Sebayang, Ova Dewi, Toga Panjaitan, Kartika Rahmasari, Muhammad Rowi Darmawiredja, Ridho Irwansyah, agustdanang ismoyo & Amardeep M. Dugar Abstract: This study explores the use of perforated egg crates as a dynamic shading system to improve daylight quality by achieving better uniformity in open-plan offices. Glazed curtain walls, although a popular choice in modern open-plan offices, can cause problems especially in tropical climates, such as glare and heat particularly near the windows. As egg crates (EC) generally perform better as shading devices than plain horizontal or vertical systems, this study simulated three different combinations of perforated, solid, overlapping and non-overlapping egg crate models for an existing open-plan office building in Indonesia. Daylight measurements of the existing horizontal shading device without any egg crate (NO-EC) were first recorded. Subsequent simulations of non-overlapping perforated (EC-NP) egg crate models with different blade widths and blade rotation angles in accordance with the sun elevation angles on specified working hours were performed. Similar simulations were then performed for two combinations: other combinations of overlapping solid (EC-OS) and overlapping perforated (EC-OP) egg crate models. Finally, a full-scale site mock-up of the EC-NP and NO-EC were tested under real-life climatic conditions. Results show that EC-NP provides better uniformity than the other two combinations, which is within the range of 0.59 – 0.99. This is due to the deeper penetration of daylight achieved by the overlapping placement of the horizontal blades in front of vertical blades, while keeping the building envelope shaded.

Research Publication Journal: LEUKOS – Journal of the Illuminating Engineering Society Manuscript Title: Biodynamic lighting – reviewing foundational considerations for ‘life-centric’ lighting Article Type: Original Research Authors: Amardeep M. Dugar Abstract: Background – As many aspects of animal, human and plant behaviour and survival are being perturbed by widespread exposure to artificial light at night (ALAN), lighting professionals are in the middle, attempting to make design decisions that directly affect these life forms. Research shows any light exposure higher than the nighttime natural environment will have negative impact on various life forms during the nocturnal phase. This paper aims to provide a design process for ‘life-centric’ lighting with good human and non-human outcomes for all life-sustaining behaviours on earth driven by phototropism, phototaxis, photoperiodism and circadian entrainment as the foundational consideration. Methods – Fundamental understandings of how light information is used by these life forms in a way crucial for development, growth and survival is provided in the paper. Key references are consolidated and synthesized using PRISMA 2020 with goals of supporting knowledge translation into pragmatic lighting strategies in a manner useful for lighting professionals. Results – A process for life-centric lighting design using an existing process for human-centric lighting design involving lighting intensity and spectrum along with spatial and temporal patterns is provided, which can dovetail with decision-making processes that are within the workflow of lighting professionals. Conclusions – Well-designed studies with a wider range of light intensities and spectrum and well-defined lighting properties, along with better modes of communication between lighting professionals and ALAN researchers are recommended to facilitate the realization of biodynamic lighting solutions that will support good human and non-human outcomes.

Research Publication Journal: Light & Engineering Manuscript Title: Lighting for Green Walls Article Type: Original Research Authors: Peter Raynham and Amardeep M. Dugar Research Contributors: David Gilbey and Roger Sexton Research Location: The Bartlett, UCL's Faculty of the Built Environment Research Sponsors: Xicato, lumenpulse alphaLED, LITE Architectural and Wonder Wall Abstract. This study demonstrates the possibility of growing green walls in normal commercial building environments with lighting designed primarily for aesthetic reasons, rather than the promotion of plant growth. Lighting is a key resource required for the growth and maintenance of robust green walls within interior environments. The study evaluated the appearance and growth of green walls with electric lighting used primarily for aesthetic reasons. Three identical green walls with six different plants were illuminated using three different white LED light sources for a period of five months. Plant health was monitored and documented in terms of successful growth patterns. One hundred and six subjects appraised the appearance of the walls using questionnaires. Findings of this study indicate that it is indeed possible to grow and maintain green walls in normal commercial building environments with lighting designed for aesthetic reasons. Further, key species were identified as appropriate for growing on internal green wall setups. #greenwalls #biophilia #biophiliclighting #lightingdesign Original manuscript can be accessed here: https://lnkd.in/guHaGyFC Pre-print of this manuscript can be accessed here: https://lnkd.in/gcwtnq6Y

Research Publication Journal: IESANZ - The Lighting Society's Journal for Lighting Manuscript Title: Lighting characteristics and design considerations to facilitate placemaking for World Heritage Sites Article Type: Original Research Authors: Shahabedin Zeini Aslani, Amardeep M. Dugar, Reyhaneh Mozaffar Abstract: This paper aims to establish lighting as a key facilitator in the placemaking processes for World Heritage Sites. Placemaking is a process of designing, managing, planning and programming the development of shared public spaces within the urban fabric. Research methods inspired from ethnography such as interviews, observations and questionnaires are used to gather data from three main groups of people related to the lighting of World Heritage Sites namely: heritage experts, lighting designers, and locals and visitors. Two UNESCO designated World Heritage Sites are investigated as case studies: Saint-Avit-Sénieur in Dordogne, France and Naghshe-Jahan-Square in Isfahan, Iran. Thematic analysis of the data collected from these investigations reveal key lighting characteristics and lighting design considerations that can facilitate the placemaking process for World Heritage Sites. The lighting characteristics include: avoiding over-lighting, overly theatrical lighting and homogeneous lighting; balancing floodlighting; preventing glare; providing flexible and harmonious lighting. The lighting design considerations include: accounting meanings and values; amplifying narratives; balancing genders; building attraction and excitement; creating layers; enhancing atmospheres; ensuring safety; improving functionality; offering interpretations; and supporting activities.
