Students are exposed to various environmental stimuli at their home study places. However, different students have different preferences in terms of indoor environmental quality (IEQ) aspects and psychosocial aspects of these places. A previous study on students' preferences of their study places resulted in nine profiles based on their IEQ and psychosocial preferences of their study places. It was found that there are profiles that were not highly concerned with sounds at their study places, while other profiles are concerned about sounds. Accordingly, this present study aims at clustering students based on their acoustical-related preferences of their study places. A questionnaire survey was completed by 451 first-year bachelor students at the Faculty of Architecture and the Built Environment at TU Delft. TwoStep cluster analysis was performed, and five unique profiles were identified. These are: 1) sound extremely concerned introvert, 2) sound unconcerned introvert, 3) sound partially concerned introvert, 4) sound concerned extrovert, and 5) sound unconcerned extrovert. The outcomes of this study showed that TwoStep cluster analysis facilitate researchers to better understand the different profiles of students based on their acousticalrelated preferences in study places.@en

People are staying indoors for most of their time (on average 90%), where they are exposed to different environmental stimuli (e.g., noise, temperature) that are related to the indoor environmental quality (IEQ) factors (Bluyssen, 2020). Students in higher education spend substantial time at their study places (at home or educational buildings) for their study-related activities (Beckers et al., 2016a). Noise is one of these environmental stimuli that could affect the students’ health and comfort. It was found that noise affected students’ health (Tristan-Hernandez et al., 2017), perception (Dzhambov et al., 2021), and performance (Shu & Ma, 2019). However, previous studies mainly focused on the students’ sound environment perception in classroom settings, while few (e.g., (Ramu et al., 2021) and (Beckers et al., 2016b)) investigated their perception in their study places. This study aims to identify the sound sources that students are exposed to at their home study places. Furthermore, this study shows to which extent students are satisfied with the sound environment of their study places.@en

Research has shown that students differ in their preferences of indoor environmental quality (IEQ) and psychosocial aspects of their study places. Since previous studies have mainly focused on identifying these preferences rather than investigating the different profiles of students, this study aimed at profiling students based on their IEQ and psychosocial preferences of their study places. A questionnaire was completed by 451 bachelor students of the faculty of Architecture and the Built Environment. A TwoStep cluster analysis was performed twice separately. First, to cluster the students based on their IEQ preferences, and second based on their psychosocial preferences. This resulted in three clusters under each cluster model. Then, the overlap between these two models was determined and produced nine unique profiles of students, which are: (1) the concerned perfectionist, (2) the concerned extrovert, (3) the concerned non-perfectionist, (4) the visual concerned perfectionist, (5) the visual concerned extrovert, (6) visual concerned non-perfectionist, (7) the unconcerned introvert, (8) the unconcerned extrovert, and (9) the unconcerned non-perfectionist. A number of variables was found to be significantly different among these profiles. This study’s outcome indicates that studying the overlap between IEQ and psychosocial preferences is required to understand the different possible profiles of students. @en

As hospital workers are generally less satisfied with comfort than patients and limited information was available on health and comfort in outpatient areas, a PhD study was carried out on staff in outpatient areas. The study design, main conclusions and recommendations of this PhD study are discussed. To gain a more representative view of the occupants’ perceptions, IEQ and social comfort were included. Social comfort was studied as a new construct, based on literature of privacy and crowding. A mixed methods approach was selected to justify the occupants’ reallive experience of the physical environment. First, data were collected with building inspection of six hospitals and a questionnaire responded by 556 outpatient workers. Subsequently, a representative sample of them (17) was interviewed with photo elicitation. The survey was conducted before the COVID-19 pandemic, the interviews during the COVID-19 pandemic. Data were analysed with several techniques to describe comfort and health (descriptive statistics), determine associations of work and building-related aspects with comfort and health (regression analyses), to identify IEQ and social comfort profiles (Two-Step Cluster analysis) and to identify changes in preferences due to the COVID-19 pandemic (content analysis). The different analyses strengthened associations of contextual aspects, such as room types, with health and comfort. Also, the results indicate limited overlap of social comfort and IEQ. Therefore, it is recommended to include room types and social comfort aspects in future studies. Furthermore, as the results show differences in the occupants’ preferences associated with differences in health (IEQ) and activities (social comfort) while their preferences can change in time, it is recommended to develop design strategies for an optimal fit beyond standardized solutions.@en

Gezondheid en comfort van mensen in de gebouwde omgeving, thuis, op het werk, op school, onderweg, of in de vrije tijd is een complex onderwerp, waarbij natuurkunde, gedrag, fysiologie, energiegebruik, klimaatverandering, architectuur, engineering en techniek een rol spelen. De manier waarop mensen iets voelen, ervaren en zich gedragen is gerelateerd aan de kwaliteit van hun omgeving, beschreven door de thermische, lucht, licht en geluidkwaliteiten. Bovendien hebben de veerkracht van gebouwen en installaties om aan de veranderende eisen en voorkeuren te voldoen en het vermogen van mensen om te reageren op nieuwe gebouwen en installaties invloed op hun perceptie en gedrag.@en

Inspired by the strong vision of the hospital organization on hospitality, a new hospital was built with theintention to provide an open environment which supports privacy and interaction between the occupants. This studyevaluates the satisfaction of patients, visitors and nursing staff with shared and single bedrooms, regarding privacyand interaction with others.Background – The hospital organization@en

Against the backdrop of an increasing need for healthcare, staff shortages and relatively high rates of sick leave, understanding of wellbeing (comfort and health) of hospital workers is important. This research aims to provide a contribution, through a mixed-methods approach, with broad and in-depth insights into comfort and health. Therefore, data have been collected from questionnaires, building inspections, interviews, and photos, and analysed with several techniques. Personal, work, and building-related aspects were included in data collection, because a preliminary literature review identified mutual relations with comfort and health. As previous studies on outpatient workers were missing, while staff is generally less satisfied with comfort than patients, this research focuses on staff in outpatient areas. To gain insights into the outpatient workers’ comfort and health, four important aspects are highlighted: differences in comfort in relation to room types, occupant profiles differentiated by the individuals’ preferences and satisfaction, changes of preferences due to contextual changes, and associations of health with building-related aspects. This research builds on previous studies which identified indoor environmental quality (IEQ) profiles of home occupants and school children. New are social comfort profiles, comparison between room types and contextual influence on preferences, as well as the studied occupant group and building. The study enables academical and practical exploration of preferences and perceptions of comfort and their integration in the design process. @en

While the pressure on hospital workers keeps growing, they are generally more dissatisfied with their comfort than other occupants in hospitals or offices. To better understand the comfort of outpatient workers in hospitals, clusters for preferences and perceptions of the indoor environmental quality (IEQ) and social comfort were identified in a previous study before the outbreak of the coronavirus disease 2019 (COVID-19) pandemic. This qualitative study explains the outpatient workers’ main preferences for comfort during the COVID-19 pandemic. Semi-structured interviews and photo-elicitation were used. Contextual changes due to the COVID-19 pandemic were included. The questions in the interviews were based on the characteristics of the profiles, corresponding with the clusters. The data were analyzed with content analysis according to the steps defined by Gioia. Seventeen outpatient workers who had been part of the previous study participated. For some outpatient workers differentiation of preferences was illogical due to interrelations and equal importance of the comfort aspects. The main changes in perceptions of comfort due to the pandemic were worries about the indoor air quality and impoverished interaction. Because the occupants’ preferences for comfort can change over time, it was suggested that further development of occupant profiles needs to accommodate changes.@en

Building-related health symptoms are multifactorial, hence a comprehensive study is needed to identify associations of such symptoms with building aspects. Previous studies have identified certain building characteristics as risk factors for both dry eyes and headaches, which are among the most prevalent symptoms suffered by office workers. This study investigated associations of dry eyes and headaches with building characteristics in outpatient areas because these conditions may vary between office and hospital buildings. A survey was performed in six hospital buildings, which included administering a questionnaire to 556 outpatient workers and an inspection of the building locations, services and 127 outpatient rooms. Multivariate regression models were produced for dry eyes and headaches. Both models were adjusted for personal and work-related aspects. The prevalence of self-reported dry eyes and headaches in outpatient areas was related to building-related aspects that affect the indoor air quality and visual quality, and to room types. In general, this study is consistent with previous office studies. However, a specific finding of this study is the association of the most frequently used room types and the presence of a window to the corridor with dry eyes and headaches.

It is well known that the demand on hospital staff is increasing and that their comfort and health may be affected negatively by dose and building-related aspects. Comfort and health may differ between hospital departments. However, outpatient areas are understudied. To better understand comfort and health of staff in outpatient areas a survey was performed in which social comfort, personal and work-related aspects were all accounted for. This study aimed to identify comfort and health in relation to different room types. Of the 1694 invitations that were sent to outpatient staff of six buildings, 566 respondents (33%) were included in the analysis. There was little difference in the prevalence of the main self-reported symptoms, dry eyes and headache, and indoor air complaints, whereas acoustical, visual, thermal and social comfort differed statistically significantly between those working in different room types. Compared to other (inpatient) hospital and office studies, the prevalence of symptoms and dissatisfaction with comfort was high, especially dissatisfaction with daylight. Considering the dynamic use of workplaces in outpatient areas and the high ERI, this study reinforces the necessity for inclusion of personal and work-related characteristics in studies on comfort and health of occupants.@en

Comfort and health of outpatient staff is important due to the growing demand of healthcare and its crucial influence on society. Previous studies have mostly focused on the perception of comfort and indicated a large prevalence of building-related symptoms and dissatisfaction with comfort of staff in hospital buildings. Unfortunately, limited information was available of the individual preferences in relation to building aspects, especially in outpatient areas. This study aims to understand the preferences of outpatient staff in relation to their comfort, health, work- and building-related aspects. Data were collected with a survey from 556 outpatient workers in six hospital buildings and building inspection of 107 rooms. TwoStep cluster analysis was performed to identify groups with clear differences in preferences and comfort, that justify the variation of individual comfort and preferences of outpatient workers. Six clusters were produced for preferences and comfort with IEQ; three clusters were produced for preferences and comfort with social aspects. The clusters indicated that preferences and comfort of IEQ are related to health. The social clusters varied in activities of outpatient staff. As the overlap of the profiles of the IEQ clusters with the profiles of the social clusters was limited, the results suggest that it is important to study both simultaneously. Surprisingly, relations with building-related aspects were for both cluster-sets limited. This suggests that outpatient staff members do not relate their preferences to the actual building where they are working.

To identify current problems in the classroom and to conceptualize design solutions by primary school children to solve these problems, 335 children from seven primary schools participated in a workshop held in the Experience room of the SenseLab, comprising of two parts. In part 1, the children were asked to think about their own classroom at school and to choose an IEQ-problem in their own classroom that they are bothered with. In part 2 of the workshop, the children were asked to imagine they are an inventor or scientist in 2040 with all resources available and to make a design for the future. The content analysis of the problems and solutions appearing in the drawings and the written text resulted in 5 themes (light, noise, temperature, air and other than IEQ) and 16 sub-themes (11 for the problems and 5 for the solutions). Noise-related problems were most frequently reported (58%), followed by temperature (53%), air (22%), and light (16%). Girls reported more problems than boys, which is possibly related to a better recollection of negative feelings towards those problems in their classrooms. 47% of the children proposed solutions related to more than one IEQ-problem. Solutions ranged from existing solutions, for example headphones to protect against noise to far-fetched solutions such as send noisy children away by means of a rocket. The outcome showed that children can be valuable contributors in co-designing ‘new’ or ‘adapted’ classroom environments.

For several years indoor comfort is measured in halls of hospitals by architecture students from the Delft University of Technology. Questionnaires and interviews have shows that patients and visitors have very few complaints about the indoor comfort in hospital halls. This, in hindsight, is not so very surprising. Patients and visitors usually come out of the cold into the hallway. A hallway which is at least marginally warmer, a hallway where it does not rain and hallway that is sheltered from the outside wind. Secondly, the indoor comfort is not the main concern of the patients and visitors entering the hospital. The patient’s and visitor’s upcoming consults with the doctors or nurses is much more important. Coming from the consult, patients and visitors always have the choice to immediately leave the hospital if they do not like the indoor comfort. Complaints from staff, however, are very common. Staff personnel usually complain about low temperatures and draught. A reception desk is the main workplace in a hospital hall. A reception desk can be closed, i.e. physically separates the personnel from the environment of the hall. A reception desk can also be open, thus without a physical separation between personnel and patients and visitors. In a hospital, in general, an open reception desk is favoured for a more welcoming atmosphere for patients and visitors. This more open reception desk, however, often causes the personnel to experience low temperatures and draught. From this study it is clear that it is very difficult design a thermally comfortable reception desk in a hospital. The quest for a reception that expresses openness and transparency clearly hinders the design for a comfortable reception desk. On the other hand, the small number of people at the reception desk is in no comparison to the hundreds of staff and patients for which the hospital is also designed. Many solutions to improve thermal comfort at a reception desk are already known. The exact cause of the experienced draught and the best solutions, however, are difficult to determine. Scale models or CFD simulations should be used as a guide for design a reception desk in a hospital or when solving thermal comfort problems. A new cause of draught, people moving past the reception desk, was identified and quantified. As a result, a completely open reception desk inside a large atrium with a lot of people moving past might not be possible without either closing off the reception desk, or increasing the temperature at the reception desk.@en

Due to the increasing demand for healthcare and the large impact on the finance of hospital buildings in the near future, study is needed on aspects that affect health and comfort of patients and staff in hospitals. Therefore, a literature review was performed on studies related to specific hospital departments and occupant groups, in order to contribute to a better understanding of relations of comfort and health indicators and the physical environment. Differences in comfort and health of occupants were compared between departments, and between occupant groups. It was concluded that staff was generally less satisfied than patients were. Some of the indicators studied (occupant, dose and building-related indicators) varied between departments. Most studies focused on a single dose or building-related indicator, although the occupant-related indicators, such as privacy, infection rate or mortality, were related to more than one dose or building-related indicator. It was concluded that staff in particular have been understudied in relation to the variation of health and comfort aspects in different departments.

The indoor environmental quality, control, layout and appearance may affect comfort and satisfaction of patients, as well as visitors and staff in hospitals. Due to differences in activities, duration of stay and health status, needs of the different groups may vary. In order to design hospitals, which positively support comfort and satisfaction of all occupants, information is needed about satisfaction and the perceived importance of different factors. This study compared comfort and satisfaction of patients, visitors and staff with inpatient bedrooms (single and multiple bedrooms). A questionnaire was designed with rating scale questions; 499 respondents participated. The groups varied in their satisfaction. Staff was the least satisfied group. All groups were most satisfied with the appearance of the patient room and least satisfied with control. A qualitative study on control may strengthen the validity of the questionnaire for future research. In order to gain more insight in the importance of different aspects, an extension of the questionnaire, regarding questions about health.@en

To study the combined effect of different environmental factors on children in a classroom setting, 250 children from seven primary schools were exposed to 36 different environmental configurations (‘all’ and ‘fewer’ acoustical panels; ‘displacement’ and ‘mixing’ ventilation; sound type: ‘children talk’, ‘traffic’, and ‘none’; and ‘direct’, ‘indirect’ and ‘soft’ lighting). In a four-way factorial design, they assessed with 18 groups on eight different days temperature, draught, noise, light and smell. Correlation, three-way ANOVA, comparison tests and multi-regression analysis were used to analyse relationships, and main, cross-modal and interaction effects. The results show that more acoustical panels had a positive effect on the children’s assessment of sound. Sound type had a main effect on the assessment of sound. Statistical significant cross-modal effects were found for lighting and sound type on the assessment of smell. Significant three-way interactions between ‘Vent’, ‘Sound’, and ‘Light’ types were found for smell and light in the ‘fewer panels’ situations; and for light in the ‘all panels’ situations. Multiple-regression analysis also showed that perception of smell was significantly related with draught, sound and light perception in ‘fewer panels’ conditions. Further studies on these cross-modal interactions are recommended, specifically at individual level.@en

Various studies have shown that the architecture and design of a nursing home can have a profound impact on the sense of home of old people residing in the nursing home, next to psychological and social factors. However, adequate guidance on how these factors can be operationalized in practice is not provided for architects and interior designers. This study investigated which architectural factors contribute to a sense of home and how these can be implemented in the design guidelines. Two existing data sets were used, combining the most recent evidence from the literature and experiences of residents, family caregivers, and professional staff of Dutch nursing homes. These analyses resulted in theoretical implications for the private space, quasi-public space, the look and feel of the nursing home, and the outdoors. Furthermore, these analyses were used for the design of a demonstration apartment that integrates the factors of the sense of home. This description was concluded by a checklist for practice, in which design guidelines were formulated. A holistic understanding of which factors influence the sense of home could lead to improvements of the sense of home of nursing home residents.@en

Background The sense of home of nursing home residents is a multifactorial phenomenon which is important for the quality of living. This purpose of this study is to investigate the factors influencing the sense of home of older adults residing in the nursing home from the perspective of residents, relatives and care professionals. Methods A total of 78 participants (n = 24 residents, n = 18 relatives and n = 26 care professionals) from 4 nursing homes in the Netherlands engaged in a qualitative study, in which photography was as a supportive tool for subsequent interviews and focus groups. The data were analyzed based on open ended coding, axial coding and selective coding. Results The sense of home of nursing home residents is influenced by a number of jointly identified factors, including the building and interior design; eating and drinking; autonomy and control; involvement of relatives; engagement with others and activities; quality of care are shared themes. Residents and relatives stressed the importance of having a connection with nature and the outdoors, as well as coping strategies. Relatives and care professionals emphasized the role the organization of facilitation of care played, as well as making residents feel like they still matter. Conclusions The sense of home of nursing home residents is influenced by a multitude of factors related to the psychology of the residents, and the social and built environmental contexts. A holistic understanding of which factors influence the sense of home of residents can lead to strategies to optimize this sense of home. This study also indicated that the nursing home has a dual nature as a place of residence and a place where people are supported through numerous care strategies.@en

Purpose. To provide an overview of factors influencing the sense of home of older adults residing in the nursing home. Methods. A systematic review was conducted. Inclusion criteria were (1) original and peer-reviewed research, (2) qualitative, quantitative, or mixed methods research, (3) research about nursing home residents (or similar type of housing), and (4) research on the sense of home, meaning of home, at-homeness, or homelikeness. Results. Seventeen mainly qualitative articles were included. The sense of home of nursing home residents is influenced by 15 factors, divided into three themes: (1) psychological factors (sense of acknowledgement, preservation of one's habits and values, autonomy and control, and coping); (2) social factors (interaction and relationship with staff, residents, family and friends, and pets) and activities; and (3) the built environment (private space and (quasi-)public space, personal belongings, technology, look and feel, and the outdoors and location). Conclusions. The sense of home is influenced by numerous factors related to the psychology of the residents and the social and built environmental contexts. Further research is needed to determine if and how the identified factors are interrelated, if perspectives of various stakeholders involved differ, and how the factors can be improved in practice.@en

Omgeven door park en bos vormen twaalf huizen Boswijk een veilig dorpje in een groene omgeving in Vught (Figuur 13.1). Boswijk is ontworpen met veel aandacht voor het gevoelige karakter en de onorthodoxe eigenschappen van zijn bewoners, ouderen met dementie. In nauwe samenwerking met de opdrachtgever en een sociaal geriater is een bezielde zorgvisie met kennis en intuïtie vertaald in een veilig en herkenbaar huis. De impact van de omgeving op zelfredzaamheid, cognitie en welbevinden van de bewoners in Boswijk wordt zichtbaar aan de hand van de beschrijving van een dag uit het leven van een fictieve bewoonster Heleen. Haar kortetermijngeheugen werkt slecht en ze kan geen plannen maken; voor de meeste dagelijkse dingen moet ze aangespoord worden. Dat gaat alleen goed als haar zintuigen voldoende, maar niet teveel geprikkeld worden. Boswijk helpt haar dagen een ritme te geven. [...]@en
