Background: The COVID-19 pandemic placed healthcare design at the heart of the crisis. Hospitals faced challenges such as rapidly increasing their intensive care unit capacity, enabling physical distancing measures, quickly converting to telehealth and telework practices, and above all, keeping patients and staff safe. Improving flexibility in hospital facility design and adaptability of hospital operations to function in “crisis mode” can be seen as ways of future-proofing for pandemics. In a design brief, flexibility is typically mentioned as an important target. Meanwhile, robustness of technical infrastructure is called for, and standardization at unit level with single-occupancy inpatient accommodation may be considered a way to enhance flexibility and adaptability in dealing with a surge in infectious patients. Aim: To future-proof facility design with pandemic preparedness and resilience in mind, this study evaluated what kinds of interventions were taken in Dutch hospital facilities and what perspectives need to be considered when hospitals operate in crisis mode. Methods: We have collected data from facility and estate professionals from 30 Dutch hospitals. Using a practice-based approach, in-depth interviewing helped uncover and compare successful operational strategies and design elements that provided the flexibility needed in the early stages of the recent crisis. Results: As we looked at existing facilities and alterations made to allow hospitals to operate during the COVID-19 pandemic, we discovered that staff availability and adaptability were deemed crucial. Conclusion: We add the perspective of staff as an essential factor to be considered when future-proofing hospital facility desigr crisis mode operation.

Upgrading existing social housing (SH) requires user-centred participatory processes to promote values. Comparative case studies in Brazil, Germany, the Netherlands, and the UK are presented. Living Labs (LLs) were conducted for the delivery of user values and to promote an informed decision-making process. Tools and LL activities were tested to engage stakeholders in the upgrading process, support the co-creation of solutions and address social and societal challenges. The main research aims were to facilitate SH upgrading processes focusing on the delivery of value for users, achieving end-user empowerment, as well as assessing participatory decision-making through LLs. Research goals were achieved in each case study setting. The evaluation of specific cases informed a conceptual framework and guidelines to facilitate upgrading through LLs in varied SH landscapes.@en

The door between the semi-public corridor and the single-occupancy patient room of a newly built University Medical Centre in the Netherlands has been heavily debated during its Evidence Based Design (EBD) and experience-informed design. It was also heavily debated since the wards came into use in 2018. It is well known that, regarding door design, a trade-off has to be made between aspects such as privacy, visibility, and safety. This makes our case study exemplary for the trade-offs to be made in EBD practice. This study traces back to how the design decisions for the door, dating from 2011, were made. Safety, privacy, control, and support for the social and emotional wellbeing of patients, relatives, and staff were the aim, but this is not experienced as such by all concerned. This case study evaluation highlights the tension between EBD principles and everyday practice, where the interplay between ‘bricks, bytes, and behavior’ has to be considered, and every consciously debated design solution might bring new and unforeseen challenges elsewhere. Our practice-based research combines the analysis of documentation on the design decision-making process with evaluation interviews with nurse managers in 2019. Our findings on ‘the (Dutch) patient door debate’ can contribute to awareness of trade-offs to be made in health facility design, complemented with supportive IT systems and efficient and effective staff workflows. It can enhance the understanding of the many aspects that need to come into consideration during design dialogues with experts and end-users.@en

This paper discusses knowledge sharing through scenario development as applied in the interdisciplinary and international research project uVITAL. It focused on user-oriented upgrading of the social housing stock. The aim was to gain deeper insights into the specificities and commonalities of the four country case studies involved. Two online workshops, which included various steps for scenario development, were particularly important during the COVID-19 pandemic when face-to-face exchanges were not possible. A Miro whiteboard was very useful as a technical communication and collaboration tool. This paper outlines the benefits and challenges of scenario development to facilitate communication and collaboration between researchers from different disciplines and national and cultural backgrounds, particularly in online and hybrid settings. The well-structured process of scenario development was an important step in the project, moving from passive to active knowledge sharing. This included issues of content, geographical and cultural diversity and methodological openness.@en

The COVID-19 pandemic placed healthcare design at the heart of the crisis. Hospitals faced challenges such as increasing their ICU capacity and enabling physical-distancing measures to prevent infectious spread. They also needed to co-house suspected COVID patients and nonCOVID patients with different requirements and enforce separate entrances and routes to keep staff and patients safe. It is suspected that even in a fully vaccinated world, other pandemics are waiting in the wings. In a design brief, flexibility is typically mentioned as an important target, and single occupancy inpatient accommodations may be considered as a way to enhance flexibility. To gain insight into and inform future hospital design, this study evaluated what operational coping strategies and design solutions were considered important enablers to increase ICU capacity and support different patient flows, and what design solutions enabled physical distancing. We have collected data from 30 Dutch hospital organizations, including some recently opened hospitals, with 100% single occupancy inpatient accommodation. Using a practice-based approach, in-depth interviewing was combined with document and multimedia analyses to analyze and compare successful operational strategies and design elements that helped provide the flexibility needed in this recent crisis. As we looked at existing facilities and alterations made to allow hospitals to operate in ‘crisis mode’ during the COVID-19 pandemic, we presented emerging design considerations for future healthcare facilities that, preferably, can also be implemented in renovations or refurbishments. We add the perspective of staff as a limiting factor in a hospital’s pandemic preparedness.@en

The design of a new hospital is typically used as a catalyst for change, redesign, and the implementation of new work processes to improve health services. Perceived outcomes after relocation may be linked to the success of co-design and stakeholder engagement processes. Especially in striking the right balance between the building (bricks), processes and supporting IT (bytes), and work processes (behavior). Even when stakeholders are engaged in the design, that does not guarantee that their needs will be safeguarded during trade-offs in various phases of decision making. Furthermore, the time window between engagement and project delivery may contribute to a mismatch in perceived outcomes after relocation. This study aims to gain insight into the possible causes of the perceived mismatches as expressed by ward managers some 12 months after relocation. This was some six years after the design of the facility was completed. It will increase our understanding of the complexity of design, construction, and transition processes that have to deal with a gap in time between design and use. We adopt an interpretive case study approach in which in-depth interviewing is combined with an extensive analysis of documents collected over time. We found transformative change requiring an integrative approach to the Bricks and Bytes throughout the whole process of designing, constructing and taking them into use, with stakeholder engagement as a key element. Additionally, we found that health care worker behavior was not considered sufficiently in a predominantly rational design and implementation process focusing on patient centeredness.@en

Complexity has been known as a crucial psychological factor influencing the evaluation of the building facades preferences. However, little is known about the role of physical attributes of preferred building facades on perceived visual complexity. The objective of this study is to assess perceived visual complexity of urban building facades in terms of physical attribute in different levels. Discrete choice experiments were used to study the perceived visual complexity of preferred building facades. A sample of 213 students from Golestan University evaluated preference and perceived visual complexity of 36 pairs of images based on ten physical attributes of building facades in different levels (material (brick, stone), the contrast of materials (absent, present), color (absent, present), ornament (high, low), curve (straight, curved), vegetation (plants, no plants), windows orientations (vertical, horizontal), fenestration (large, small), articulation (side recesses, flat) and architectural style (modern, classic, traditional). The results revealed that all physical attributes of preferred building facades were found significant on perceived visual complexity expect for three attributes: architectural style, color and window to wall size. Thus, participant preferred a high-ornament facade with curved lines, vegetation, classical style, articulation, contrast between materials, as well as vertical windows. The articulation and ornament attributes were the most significant on perceived visual complexity. The results of this study can help city planners, architects, and designers to design facades with more general preferences and reduce the visual pollution of the cities.

With the need to increase total revenues, airports have begun to use commercial retail. A well-designed airport may provide great service to clients and consumers and increase their satisfaction and in turn their spending behaviours. Since there is suggestive evidence that there might be cultural associations of white, purple or black with different emotional loadings to these colours across cultures, the present study investigated passengers’ preferences for architectural design characteristics of an airport in a new cultural setting. Discrete choice modelling was used to measure the passengers’ preferences for 10 interior design characteristics of the passenger terminal using 3D renderings. Data on 435 passengers were collected at Mehrabad International Airport, which also included passengers’ emotions. Passengers in the terminal hall preferred a curved and transparent ceiling, material in warm colours, cool lighting, with low width and low height, greenery and without any decorations. When compared to other studies, it may well be that passenger preferences for lighting and certain colour schemes reflect geographical or cultural differences. For other interior design characteristics, preferences relating to the shape of the ceiling and the amount of daylight, as well as the presence of greenery, may well be reflections of passengers’ restorative needs.

This study investigates the motives of clients, contractors and subcontractors and underlying conditions favoring strategic partnering formation in the Dutch retrofit market. In-depth interviews were conducted with six clients, six contractors, and two subcontractors concerning four cases in the Netherlands. To identify motives, the data from the 14 interviews were coded with Atlas TI based on a theoretical framework. The thematic analysis revealed the main motives. The main finding of this study was that clients and contractors form strategic partnerships for different reasons: clients unite to exploit the knowledge and capabilities of their supplying partners, while contractors and subcontractors unite to improve their market position. Both motives may be exchanged when clients offer contractors and subcontractors a long-term perspective. This finding shows managers in the construction industry that, to maintain a strategic partnership, it is important to understand and discuss the motives of each partner and how they can be exchanged.@en

A significant majority of the literature on natural environments and urban green spaces justifies the preferences that people have for natural environments using four predictors defined by Kaplan’s preference matrix theory, namely coherence, legibility, complexity, and mystery. However, there are no studies implicitly focusing on the visual attributes assigned to each of these four predictors. Thus, the aim of this study was to explore the influence of nine visual attributes derived from the four predictors of Kaplan’s matrix on people’s preferences in the context of urban parks. A discrete choice experiment was used to obtain responses from a sample of 396 students of Golestan University. Students randomly evaluated their preferences towards a set of potential scenarios with urban park images. The results of a random parameter logit analysis showed that all of the attributes of complexity (variety of elements, number of colors, and organization of elements) and one attribute each of coherence (uniformity), mystery (visual access), and legibility (distinctive elements) affect students’ choices for urban parks, while one attribute each of mystery (physical access) and legibility (wayfinding) did not affect the choices. Furthermore, the results indicated a preference for heterogeneity of the attributes. The findings of this study can provide instructions for designing parks.

Purpose – To explore how and why the social structures of strategic partnerships are shaped by actors and how these interrelate with a team’s interpersonal relationships over time. Grasping the complexity of this interplay is essential if we want to comprehend what actually goes on in these partnerships and understand why actors often disengage from them.
Design/methodology/approach – In three cases, 14 in-depth interviews were held with knowledgeable actors about important events and activities that influenced the relationships between partners. Interview data were triangulated with journals kept by the lead author, who participated as an engaged scholar in the three cases. Because this study took an interdisciplinary approach, new insights could evolve from the multi-level analysis.
Findings – Trust has a moderating effect on the relation between open-book accounting and the degree of control a dominant party wants to exercise. When the level of control is raised, this can signal distrust to the other partners, which can harm the relationship. When partners feel more dependent on each other’s
capabilities to reach their long-term goals, the parties seem to be less likely to put the blame on one of the partners in the case of undesirable events.
Practical implications – Managers should be aware of their power position and acknowledge the effects of power on their relationships. If long-term and close collaboration does not emerge in their partnership, it may be due to how they use their power position.
Originality/value – Thanks to the interdisciplinary approach, this is the first study that shows the significance of trust and power in maintaining strategic partnerships in the construction industry, and how trust can affect the financial rules of actors.

Informal face-to-face communication and chance encounters encourage knowledge sharing. This Post-Occupancy Evaluation (POE) examines how well a new building of a Dutch University Institute (DI) supported interaction and perceived privacy among faculty members. The study is designed as a qualitative research project with in-depth interviews among faculty members before and after relocation into the new building. The transparent and centrally organized floor plan supported face-to-face communication but generated a lack of privacy for faculty members. Not all perceived affordances of the design were planned. Lack of visual privacy and the sense of being controlled by others were related to the hierarchical position of teachers in this Higher Education Institute (HEI) between students and the dean, which caused tension and diminished their well-being.

Purpose: Decarbonising the housing stock is one of the largest challenges in the built environment today, which is getting the attention not only from policymakers but also from social housing corporations, financial organisations and users. In line with the international Paris-Climate-Change-Conference 2015, Dutch cities and housing associations have embraced this challenge with the ambitions to become carbon neutral in 2050. To reach such goals, both the rate and depth of renovation need to increase. Several technical solutions to eliminate the energy demand in dwelling have been developed and tested. Nevertheless, the intake rate of deep retrofitting is low. Despite recent developments, there are still significant barriers related to financing, lack of information and user acceptance. To address those barriers, the purpose of this paper is to investigate the relationship between energy efficiency upgrades and the cost of living. Design/methodology/approach: Focusing on walk-up apartments in the Netherlands, a framework of refurbishment measures that affect the energy efficiency was identified, and their performance was calculated. Furthermore, the rental price adjustment was estimated, taking into account the refurbishment investment and the exploitation cost of the renovated dwellings. Findings: The comparison of the energy use and rental price for the different options demonstrated how the different renovation measures affect the energy cost, the energy use, rent and cost of living. The tenants are more likely to accept the solutions that take into account the total cost of living and sustainability benefits. The study gives a holistic standpoint to the issue of energy upgrades, by quantifying the effect of the potential measures for the whole exploitation period. It has shown the potential of the different interventions to improve the performance and living conditions, without necessarily increasing the total cost of living. Practical implications: Such results aim at supporting the decision making between the stakeholders, primarily housing associations and tenants. Originality/value: The importance of the study is that it gives a holistic standpoint to the issue of energy upgrades, by quantifying the effect of the potential measures for the whole exploitation period. The cost, as a key, if not the more most decisive, issue, is put into perspective in relation to the benefit, in order to give a direction to the renovation design and arguments for the stakeholders’ dialogue. The approach of the study goes beyond cost-optimality of measures and investigated the relation between energy upgrades and cost, as a way to evaluate design variation and address the lack of information barrier in renovations. Moreover, it also proves that deep renovation is feasible without increasing in the total cost of living, which is a principal argument to promote renovations.

Using 3D design models, this study aims to better involve patients in the design of hospitals by investigating what physical environmental characteristics in hospital patient rooms are valued by patients. There is a plea for shared-decision-making and collaborative design processes with representatives from healthcare and the construction sector based on evidence and end users’ perspectives. Existing research is hampered by poor conceptualization of environmental design factors, as these are differently operationalized between medical and technological sciences. Architects communicate through visuals, whereas medical professionals and researchers tend to communicate in words. By using 3D-modeling to research the relationship between health and well-being on the one hand, and the affordances the built environment offers, this knowledge gap can be better addressed. Two hundred four respondents, 60% patients and 40% medical professionals, engaged in discrete choice experiments visualizing a single patient room. A main finding is that patients and medical professionals consistently choose for hospital rooms with the highest amount of daylight access. What this study adds is that the orientation of the windows matters as well. Horizontal windows, allowing for a panoramic view, were twice as much chosen than were vertical windows. Another important finding concerns patients’ preferences for an open door, suggesting patients prefer to stay “connected” to the outside world. This study is important as it shows, empirically, that patients may make different choices if in research the rooms are better conceptualized and thus visualized and if multiple design features are assessed as configuration rather than using a sequential, “one-design-characteristic-after-another” approach.

Decarbonizing the housing stock is one of the largest challenges in the built environment today, and is getting attention not only from policymakers, but also from social housing corporations, financial and tenants’ organisations. In line with the international Paris-Climate-Change-Conference 2015, Dutch cities and housing associations have embraced this challenge with the ambitions to become carbon neutral in 2050. To reach such ambitious goals, both the rate and depth of renovation need to increase significantly. In the Netherlands, the Energy Agreement for Sustainable Growth, indicates that 300.000 dwellings have to be renovated annually, in accordance with the Energy Performance of Buildings Directive adopted by the European Union, to improve the Dutch building stock towards energy neutrality. Several technical solutions to eliminate the energy demand in dwelling have been developed and tested. Nevertheless, the intake rate of deep retrofitting is low. Currently, most improvements in residential buildings consist of basic maintenance and shallow renovation, but broader or deeper energy renovation measures are required. Despite more recent developments, there are still significant barriers related to financing, lack of information, and user acceptance. Complex technical characteristics are not always taken into account by tenants; the focus is usually on the ease of use, comfort and living expenses.

To this end, the present study sets of to investigate the relationship between energy efficiency upgrade measures and cost of living. Focusing on the post-war, multi-family social housing in the Netherlands, a framework of refurbishment measures that affect the energy efficiency were identified, and their performance was simulated. The variations refer to the façade design, thermal envelope upgrade, winter-garden addition and reviewable energy. The energy efficiency indicator is the energy cost reduction, as well as the carbon footprint of the energy use. Furthermore, the rental price adjustment was estimated, taking into account the refurbishment investment and the operation cost of the renovated dwellings. All tested combination of variables resulted in significant energy savings, up to 70%, while energy generation was proven to be cost-effective, as it has a considerable positive effect on the energy use and the energy cost, without increasing the rental price.

The results aim at supporting the decision-making discussion between the stakeholders, primarily housing associations and tenants. The relation between the energy consumption and rental price for the different options identifies the effect of design variation and demonstrated the attractive solutions that the tenants are more likely to accept, taking into account the overall cost of living and sustainability benefits.

This study investigates how a no-blame culture affects the effectiveness of project-based design teams across different project delivery methods in the construction industry. Ninety-two team members of 34 project-based design teams assessed the no-blame culture, level of teamwork, and team effectiveness in teams that were procured through different routes. A multilevel analysis shows that the relation between integrated project delivery methods, such as design–build and strategic partnering, and team effectiveness varies across levels of no-blame culture. A mediated regression analysis found that the effect of no-blame culture on team effectiveness is mediated by teamwork. Managers of project-based design teams in the construction industry should, therefore, invest both time and effort in creating a no-blame culture and the level of teamwork in parallel. This will enhance the level of team effectiveness in integrated project delivery methods.@en

A no-blame culture is often promoted as an important driver for teamwork which in turn would lead to higher project team effectiveness in construction industry projects. The research on these relations, however, is scarce in the construction industry and mainly based on case studies. Therefore, this study investigates whether a no-blame culture in project-based design teams that work on construction projects leads to higher team effectiveness through teamwork. 92 team members of 34 project-based design teams assessed the no-blame culture, level of teamwork, and team effectiveness in teams that were procured through different procurement routes. Data were collected via online surveys from a sample of construction practitioners, such as project managers, engineers, and architects. Using mediated regression analysis of mean scores, the findings show that teamwork fully mediates the relation between no blame culture and team effectiveness. The findings demonstrate that a no blame climate significantly affects the level of teamwork and in turn team effectiveness. Managers of project-based design teams in the construction industry should, therefore, spend time and effort in creating a safe environment in which team members can share their thoughts about, for instance, the design or project related problems with other team members without being scared of the consequences on an interpersonal level. @en

The construction industry is currently undergoing digital transformation due to emerging technologies. Hence new forms of organisation are needed. Collaborating with Building Information Modelling (BIM) is complex and challenges the management of projects. The ubiquitous digital information sharing among multi-disciplinary actors in BIM-based projects, activates dense inter-organisational processes. This study offers insights into collaboration with BIM, through the theoretical lens of boundaries. By analysing two projects of BIM-based collaboration in the Netherlands, the interplay between structure and agency of collaboration was discussed. The various artefacts of BIM, as boundary objects were interpreted in multiple ways by different communities of practice and this resulted in poor communication and consequently poor collaboration. The findings challenge the prevalent view of BIM as a software artefact and showed that this view only partially supports collaboration. Additionally, a structurational view (enabled by communication, conflict management, negotiation, and teamwork) as opposed to a structural view of collaboration (e.g. BIM as a software) can fully support the implementation of digital innovations. Finally, the paper revealed a ‘tactical gap’ in the implementation of digital between strategic and operational decision-making needs fine-tuning to ensure better collaboration in projects where digital innovations are adopted. The study concludes with propositions for supporting organisation of teams through integration of activities and the management of BIM-based collaboration in projects beyond merely structural and technological approaches, which dominate the field but from a structurational view instead.

Increasing energy efficiency of the housing stock is one of the largest challenges in the built environment today. In line with the international Paris-Climate-Change-Conference 2015, Dutch municipalities and housing associations have embraced the ambition to achieve carbon neutrality for their social housing stock by 2050. However, most deep renovation designs for increasing the energy efficiency of dwellings focus on the relatively easy portion of the housing stock: postwar row housing. Furthermore, such design solutions are mostly produced without much care for architectural quality and cultural heritage, nor for testing for consumer preferences. Yet, such aspects are of major importance in tenement housing, particularly regarding the architectural quality of the huge numbers of walk-up apartment buildings from the inter- and postwar periods owned by housing associations in the larger cities. Renovation of buildings of this typology is more complex because of, among others, technical, social, and heritage factors. To support decisions in this complex context, a General Transformation Framework and a Roadmap has been developed for generating design solutions for deep renovation of representative parts of postwar walk-up apartment buildings with the aim to increase energy efficiency; retain its architectural legibility and cultural heritage value; and allow for the presentation of (end) users, with various options for adaptation to assess their preferences.@en
