“…LED task lighting and discomfort, eye fatigue, the perception of job contentment, usability, and musculoskeletal discomfort among office workers was examined using a baseline (no LED task light) versus intervention study (LED adjustable task light provided). The use of LED task lights resulted in significant improvements on the reported level of discomfort, eye fatigue, perception of job contentment and posture [ 99 ]. Other aspects of artificial lighting were found to contribute to dissatisfaction with results revealing that panel heights, high reflected glare on computer screens, desktop illuminances outside of 300–500 lx, desktop illuminance uniformity less than 0.5, and being in a workstation distant from a window were all associated with a higher levels of dissatisfaction with lighting [ 100 ].…”

Evidence for behavior modification for improved health outcomes was evaluated for nutrition, physical activity (PA), and indoor environmental quality (IEQ). The databases searched included LISTA, PubMed, and Web of Science, with articles rated using an a priori baseline score of 70/100 to establish inclusion. The initial search produced 52,847 articles, 63 of which were included in the qualitative synthesis. Thirteen articles met inclusion for nutrition: cafeteria interventions, single interventions, and vending interventions. Seventeen articles on physical activity were included: stair use, walking, and adjustable desks. For IEQ, 33 articles met inclusion: circadian disruption, view and natural light, and artificial light. A narrative synthesis was used to find meaningful connections across interventions with evidence contributing to health improvements. Commonalities throughout the nutrition studies included choice architecture, increasing the availability of healthy food items, and point-of-purchase food labeling. Interventions that promoted PA included stair use, sit/stand furniture, workplace exercise facilities and walking. Exposure to natural light and views of natural elements were found to increase PA and improve sleep quality. Overexposure to artificial light may cause circadian disruption, suppressing melatonin and increasing risks of cancers. Overall, design that encourages healthy behaviors may lower risks associated with chronic disease.

“…However, one aspect of the indoor environmental quality might influence another aspect. For instance, the user might hunch or move closer while trying to read a text that is affected by glare, reflection or poor contrast caused by poor lighting, and thus also leading to poor posture (Joines et al, 2015). The circadian rhythm, which is influenced by the lighting environment, is also responsible for the regulation of core body temperature and can indirectly impact thermal comfort (Pauley, 2004).…”

“…In addition to the direct impact on eye strain, lighting parameters also affect the posture of the user depending on the task (Rea et al, 1985). For instance, the user might hunch or move closer to the task while trying to read text that is affected by glare, reflection or poor contrast (Joines et al, 2015). Proper task lighting can help mitigate these negative effects on the posture, eye strain and visual comfort of the user (Newsham et al, 2005;Joines et al, 2015).…”

Furthermore, studies have linked exposure to blue light during night to disruption in the circadian rhythm and increased risk of breast and colorectal cancer (Stevens, 2009;James et al, 2016).…”

People spend most of their day in buildings, and a large portion of the energy in buildings is used to control the indoor environment for creating acceptable conditions for occupants. However, the majority of the building systems are controlled based on a "one size fits all" scheme which cannot account for individual occupant preferences. This leads to discomfort, low satisfaction and negative impacts on occupants' productivity, health and well-being. In this paper, we describe our vision of how recent advances in Internet of Things (IoT) and machine learning can be used to add intelligence to an office desk to personalize the environment around the user. The smart desk can learn individual user preferences for the indoor environment, personalize the environment based on user preferences and act as an intelligent support system for improving user comfort, health and productivity. We briefly describe the recent advances made in different domains that can be leveraged to enhance occupant experience in buildings and describe the overall framework for the smart desk. We conclude the paper with a discussion of possible avenues for further research.

“…In addition to direct effects of the workplace physical environment, these and a variety of other factors intersect to affect worker health and well-being in office workers. Poor lighting, temperature, and other environmental factors can lead to maladaptive postures by causing an individual to hunch or move closer to the task [11], further exacerbating one of the most common health issues in office workers, musculoskeletal disorders. In fact, musculoskeletal conditions are the most commonly referenced health problems, with an annual prevalence of musculoskeletal pain in as many as 63% of office workers [12].…”

Workplace environments have a significant impact on worker performance, health, and well-being. With machine learning capabilities, artificial intelligence (AI) can be developed to automate individualized adjustments to work environments (e.g., lighting, temperature) and to facilitate healthier worker behaviors (e.g., posture). Worker perspectives on incorporating AI into office workspaces are largely unexplored. Thus, the purpose of this study was to explore office workers’ views on including AI in their office workspace. Six focus group interviews with a total of 45 participants were conducted. Interview questions were designed to generate discussion on benefits, challenges, and pragmatic considerations for incorporating AI into office settings. Sessions were audio-recorded, transcribed, and analyzed using an iterative approach. Two primary constructs emerged. First, participants shared perspectives related to preferences and concerns regarding communication and interactions with the technology. Second, numerous conversations highlighted the dualistic nature of a system that collects large amounts of data; that is, the potential benefits for behavior change to improve health and the pitfalls of trust and privacy. Across both constructs, there was an overarching discussion related to the intersections of AI with the complexity of work performance. Numerous thoughts were shared relative to future AI solutions that could enhance the office workplace. This study’s findings indicate that the acceptability of AI in the workplace is complex and dependent upon the benefits outweighing the potential detriments. Office worker needs are complex and diverse, and AI systems should aim to accommodate individual needs.
