Abstract
Purpose
An interdisciplinary body of literature has focused on the role of lighting in mitigating patient and employee stress and error-producing conditions in hospital settings. The purpose of this study is to explore how a new circadian lighting system installed in a small pharmacy unit with no penetration of natural light is experienced by staff. Psychosocial variables, such as affective organizational commitment, perceived productivity, well-being, and satisfaction with the physical work environment, were measured to further a line of inquiry that may help facilities managers and hospital administrators make optimal choices when purchasing lighting and commissioning retrofits.
Design/methodology/approach
Post-occupancy evaluation; mixed methods survey design.
Findings
While affective organizational commitment, perceived productivity, well-being and satisfaction with the physical work environment were experienced, to some extent, by employees, low average responses about whether the setting had improved, as the circadian lighting had been installed suggest that the retrofit did not affect them as positively as expected. Counter to the intention of the installation, participants did not perceive the circadian lighting as having strongly improved their levels of stress, concentration, mood or fatigue at work.
Originality/value
More research on simulated daylighting should be done to optimize occupant responses to lighting retrofits in hospitals. This case study supports recommendations to measure relevant psychosocial variables before and after a design change. Similarly, sized units within hospitals and health care facilities that possess analogous dimensions and design constraints concerning a lack of daylight penetration will benefit from this study’s mixed methods, results and interpretations.

Abstract
Purpose
Good illumination creates an aesthetic environment that may positively influence patients’ well-being and provide comfort to the hospital staff. This study aims to focus on exploring the energy efficiency of lighting and subjective perception of the lit environment in a hospital ward to assess quality indicators of ambient lighting conditions.
Design/methodology/approach
The existing conventional tubular fluorescent lamp–based lighting system in the surveyed patients’ ward was retrofitted with light-emitting diode (LED) luminaires to explore illumination and energy parameters. Thereafter, a software lighting model was created, simulated and analyzed. A Web-based survey with five bipolar adjective pairs in a semantic differential scale was conducted with 48 participants to record and analyze their subjective responses pertaining to the variations in lamp types and surface reflectance combinations.
Findings
The findings imply that the LED tubular lamp–based illumination was deemed more adequate compared to other lamp types and the effects of variations in room surface reflectance combinations on the participants’ responses were statistically significant at α = 0.05 level. The simulated horizontal work plane average illuminance level varied from 131 to 171 lx, mean room surface exitance (MRSE) levels remained between 30 and 90 lm/m2 and overall uniformity of illuminance remained between 0.5 and 0.7.
Originality/value
In a hospital ward illuminated by LED tubular lamps, variations in room surface reflectance combinations for a constant luminous flux package output from the lamps may affect the subjective perception of users and the correlation between horizontal work plane average illuminance and MRSE is found to be highly linear (coefficient of determination > 0.97).

Abstract
Purpose
An indoor office space should not only provide adequate illuminance on horizontal planes but also cater to the physiological and psychological requirements of the occupants. This paper aims to describe a lighting simulation-based work conducted in Kolkata, India which modeled an indoor office to investigate the effects of variation in room surface reflectance combinations on user perception, mean room surface exitance (MRSE), average horizontal illuminance and overall uniformity of horizontal illuminance.
Design/methodology/approach
A fluorescent illumination system–based office space was modeled and retrofitted with tubular LED lamps in DIALux. Simulations were conducted for 16 different room surface reflectance combinations and a five-point Likert scale-type survey questionnaire was formulated to conduct a survey with 32 test subjects to assess the subjective preferability of each resultant light scene.
Findings
Simulation results demonstrate that the relationship between average horizontal illuminance and MRSE as well as between average horizontal illuminance and overall uniformity of horizontal illuminance, was statistically significant (p < 0.001). In the conducted survey, the resultant light scene arising out of the reflectance combination of wall:ceiling:floor = 60%:90%:20% was the most well-received one with 187 convinced agreements (“agree” and “strongly agree” responses).
Originality/value
This work found strong linear correlation between average horizontal illuminance and MRSE and between average horizontal illuminance and overall uniformity. A five-point Likert scale-type survey questionnaire with seven questions was formulated and validated with 32 test subjects (Cronbach’s alpha > 0.9295), which showed that the wall:ceiling:floor reflectance combination of 60%:90%:20% was the most favored choice.

Abstract
Purpose
The COVID-19 global health crisis is undeniably a global housing crisis. Our study focuses on quality of life in urban mid- and high-rise apartment housing, the fastest growing housing types in many cities around the world. This housing typology presents unique challenges relating to connection to nature, daylight and fresh air.
Design/methodology/approach
This multi-disciplinary literature review analyzes more than 100 published papers from peer-reviewed sources from environmental psychology, building science and architecture relevant to quality of life in high-rise housing, as well as more than 40 recent newspaper and magazine articles about the possible impacts of COVID-19 on housing. We identify synergies between passive design strategies and health-promoting architecture or “restorative environmental design” principles.
Findings
Post-pandemic, health-promoting apartment housing design must prioritize (1) window placement and views that support stress recovery and restoration; (2) lighting levels based on spaces that can satisfy multiple uses and users; (3) bedrooms designed for restful sleep that contribute to circadian regulation; (4) living rooms with better indoor air quality, with a focus on natural ventilation; (5) access to nature, through the purposeful design of balconies and (6) unit sizes and layouts that enable physical distancing and prevent crowding.
Originality/value
We identify new social and environmental design priorities in the form of evidence-based design principles to inform and promote healthy and restorative living environments for residents in apartment housing.

Abstract
Purpose
Using the context of a farm holiday venue, the purpose of this study is to empirically test whether textual references can have significant influences on potential consumers' affective responses and interest in advertisements.
Design/methodology/approach
In a between-subjects experiment, a reference to sunshine (the underlined phrase in the following narrative) was inserted into a Facebook advertisement for a farm holiday venue: “Relax and Rejuvenate for a couple of days on our farm. Great food, fun, and sunshine … See More”.
Findings
Results indicate that a reference to sunshine significantly improves consumers' affective responses to the advertisement and significantly increases their interest (propensity to click “see more”). This study also examines the potential influence of a textual reference to fresh air as well as fresh air in combination with sunshine. No statistically significant results are found with the fresh air reference.
Originality/value
While a number of studies have examined text-based sensory details in marketing stimuli (Magnini and Gaskins, 2010; Torto, 2016), the notion of inserting textual references to fresh air and/or sunshine in advertising has not been empirically examined in the body of the existing literature.

Abstract
Purpose
The purpose of this paper is to assess the empirical support for the use of assistive technology in the care of people with dementia as an intervention to improve independence, safety, communication, wellbeing and carer support.
Design/methodology/approach
A total of 232 papers were identified as potentially relevant. Inclusion criteria were: studies published between 1995 and 2011, incorporated a control group, pre-test-post-test, cross sectional or survey design, type of interventions and types of participants. The 41 papers that met criteria were subjected to an assessment of their validity using the model provided by Forbes. Following the assessment seven papers were considered as strong, ten moderate and 24 weak. The review is presented around the following topics: independence, prompts and reminders; safety and security; leisure and lifestyle, communication and telehealth; and therapeutic interventions.
Findings
The literature exploring the use of assistive technologies for increasing independence and compensating for memory problems illustrate the problems of moving from the laboratory to real life. The studies are usually limited by very small samples, high drop-out rates, very basic statistical analyses and lack of adjustment for multiple comparisons and poor performance of the technology itself.
Originality/value
Research to date has been unable to establish a positive difference to the lives of people with dementia by the general use of the assistive technology reviewed here.

Abstract
Purpose
Due to land resource scarcity, sustainable urban development in high-density cities has long been challenging. As such, many cities are formulating plans to “dig deep”, resulting in more citizens working and/or staying underground for longer periods of time. However, owing to the particularities of underground space, the factors involved in the creation of a healthy environment are different from those involved in aboveground developments. This study thus aims to investigate the influences of various underground environment factors on users' health through a holistic approach.
Design/methodology/approach
To achieve this aim, 12 underground sites and 12 corresponding aboveground sites are selected for a large-scale questionnaire survey, resulting in 651 survey samples. The survey covers post-occupancy evaluation of health (physical and psychosocial), underground environmental quality (visual, thermal, acoustic comfort, indoor air quality and ventilation), space design and greenery. Independent-sample T-test, Pearson correlation, multiple regression modelling and structural equation modelling are used to investigate whether significant differences exist between health of underground and aboveground users, and to develop an underground environment-health model for unveiling the significant associations between underground environment factors and users' health. To cross validate the results, an objective field measurement study is further conducted on six underground sites. The objective measurement results are used to cross validate the survey results.
Findings
The questionnaire results provide the following evidence: (1) health of underground users is significantly poorer than that of their aboveground counterparts; (2) underground development users' health is significantly affected by space design, greenery and environmental quality in terms of thermal comfort, indoor air quality, ventilation and acoustic comfort but not visual comfort; and (3) amongst the various identified factors, space design has the strongest predicting effects on human health. The field study echoes the survey findings and further unveils the relationships between different environmental factors and human health.
Originality/value
The results shed light on the importance of distinguishing between underground developments and aboveground ones in various guidelines and standards, especially those related to space management.

Abstract
Purpose
To examine whether quality-of-life of a home's occupants varies in northern and southern hemisphere homes when the orientation of the home is always to the eastern sun (as prescribed by Maharishi Vedic Architecture) not orientated differently in northern and southern hemispheres to maximise light (as prescribed by western and Feng Shui architecture design).
Design/methodology/approach
A theoretical discussion of the use of sunlight and orientation in western, Feng Shui and Vedic approach to architecture, and then a cross-sectional quantitative survey conduced in 14 countries.
Findings
The lived experience of 158 home occupants in Maharishi Vedic Architecture did not vary from northern to southern hemispheres.
Originality/value
Research of this type has never been carried out before on Maharishi Vedic Architecture, except for one other study published in 2020 by these authors which considered the lived experience of home occupants. The amount of research on the basics of Vastu architecture is minimal.

Abstract
Purpose
The study aims to explore how including biophilic elements in the architectural and interior design of assisted living facilities can improve the well-being and quality of life of older people. This research paper explores the concept of biophilic design and its potential benefits for assisted living facilities.
Design/methodology/approach
A total of 39 peer-reviewed articles were reviewed. The research involved a comprehensive review of databases such as Scopus, EBSCO, Elsevier, JSTOR and Google Scholar using keywords and Boolean operators with reference to the study. The study’s inclusion criteria for articles were restricted to academic articles published between 2013 and 2022. The analysis of the current research will offer insights into the concept of biophilic design research and its impact on the well-being and quality of life of baby boomers in assisted living facilities.
Findings
The research advocates the benefits of biophilic design to enhance the psychological well-being and quality of life of baby boomers dwelling in assisted living facilities. Biophilic design is a strategy that blends natural elements into built environments to improve our connection with nature to enhance the physical and psychological health of older people. In the context of assisted living facilities, where residents commonly experience a variety of physical and psychological health concerns, adopting biophilic design in architecture holds enormous promise.
Originality/value
The research focuses on applying biophilic design in assisted living facilities and its holistic approach to the overall well-being of older people. The conceptual model proposed in the study has defined the positive aspects of the biophilic design on the psychological and physiological health of older people. Few studies have been done on the impact of biophilic design, specifically on baby boomers.
