Trending in modern interior design frameworks is an integration of real and simulated (i.e. photographs, murals) elements of nature into buildings, and a number of interdisciplinary studies concern the effects of nature on various aspects of human functioning. The purpose of this paper is to measure employees’ self-reported levels of affective organizational commitment (AOC), perceived productivity, well-being, attention restoration and satisfaction at work to explore how each mural is conceptualized and to make recommendations to hospital administrators and facilities managers as they make decisions concerning mural design and placement. One hospital had a biophilic mural and the other had a bold abstract mural.

The research was carried out using post-occupancy evaluation and mixed-methods survey design.

Employees in both hospitals disagreed that their organizational commitment (OC), perceived productivity or well-being at work had improved since the new murals had been installed. Responses from both hospitals were also low concerning perceptions of attention restoration. Indeed, no significant differences between hospitals were found. Correlations among scales were found within hospitals that support published studies. More correlations occurred at the hospital where employees viewed the biophilic mural (e.g. between OC and perceived productivity, and between satisfaction with the physical environment and perceived productivity). At both sites, satisfaction with the physical environment correlated with OC.

The authors expected that those working within view of the biophilic mural would report stronger ratings of AOC, perceived productivity, well-being, attention restoration and satisfaction with the workplace than employees with a view of the abstract scene. No differences between groups were found; responses to psychosocial scale items asking about whether attitudes had improved after the retrofit were low or neutral for employees in either hospital. However, more correlations between scales that support existing literature were revealed for those working near the biophilic mural. Thus, the authors recommend architectural programming before a design change to gather insight on occupants’ preferences at work.

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.

Post-occupancy evaluation; mixed methods survey design.

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.

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.

This paper aims to establish a reliable scale measuring occupants’ levels of environmental trust in their work settings’ indoor air quality and explore the relationship between occupants’ levels of environmental trust and their perceived control over the air quality in their workspace.

The authors conducted occupant surveys concerning indoor air quality in an office building, and collected corresponding indoor air quality measurements. Descriptive statistics and correlation analysis results are reported to reveal occupants’ levels of environmental trust and perceived control.

Results reveal that psychological perceptions of indoor air quality can be quite neutral, even shortly after an extreme wildfire event resulting in very poor air quality in an urban area. Occupants’ sense of trust that their office building could protect them from harmful air outside, and their belief that the building could protect them from seasonal smoky conditions, each correlated positively with employees’ sense of control over the indoor air quality in their personal workspace.

This case study adds to an interdisciplinary understanding for facility managers and organizational leaders concerning a way to measure occupants’ sense of control over the indoor air quality in their building, as well as their environmental trust in terms of how protected they feel from harmful air quality conditions.

AT the close of the year we look back upon twelve very chequered months in the story of librarianship. In the field of libraries as a whole, it may be said that they held their own and indeed that some progress has been made. A few libraries have been opened, mostly branch libraries, but there have been extensions and re‐organisations of central libraries, which point to a universally developing regard for the library service. Even if this has not been dramatic in some places, it has nevertheless been real. Men who were middle‐aged before the war must, however, pass away before we get the right perspective for the conditions of to‐day; that is to say, with few exceptions. We are not speaking of librarians here, but of those who control libraries, but even librarians of the older school have sometimes found it difficult to envisage library service on the scale common in America, which, with adjustments to British circumstances, should be the scale for us throughout the Empire.
