While previous studies have highlighted the importance of incorporating environmental sustainability in building designs, there is a paucity of studies that assess the extent to which design teams in developing countries consider environmental sustainability at the building design stage. Therefore, using Zambia as a case study, this study examined the extent to which infrastructure design teams in a developing country consider environmental sustainability at the design stage.

The study used a qualitative research approach using structured interviews because there are hardly any studies which have explored the extent to which designers incorporate environmental sustainability in infrastructure designs in developing countries. The data is analysed thematically using the ATLAS.ti software.

The results show that environmental sustainability is not an important design consideration because it is secondary to functional, technical and aesthetic considerations. Environmental considerations are also made in an ad hoc manner and when it is cost-effective for the project. Regulatory requirements pertaining to environmental protection are adhered to without any cost considerations. It was, therefore, theorised that building design teams in developing countries make technical, functional and aesthetic consideration during the infrastructure design stage ahead of environmental considerations.

There is a paucity of studies that have investigated whether building infrastructure designers consider issues of environmental sustainability at the design stage in developing countries. The findings have practical implications on how developing countries can foster environmental sustainability at the design stage and avoid generating a building infrastructure stock that will require environmental resilience adaptation in the future.

This study aims to explore occupants’ perceived importance and satisfaction with high-rise students’ housing facilities’ fire safety considerations (FSCs). The specific objectives are to explore the FSCs for high-rise students’ housing facilities and assess the level of importance and satisfaction with the FSCs provided in high-rise students’ housing facilities in controlling fire outbreaks.

The study uses an exploratory sequential design with an initial qualitative phase followed by a quantitative data collection phase. Twenty FSCs were identified through the qualitative phase via semistructured interviews. Their importance and satisfaction were revealed through survey questionnaires with 168 respondents who stayed in or were involved in the operation of high-rise students’ housing facilities. Data from the qualitative phase were analyzed thematically, and those obtained from the quantitative phase were analyzed descriptively and inferentially.

The study’s findings revealed that all the 20 FSCs identified via the qualitative phase and confirmed through the quantitative phase were perceived to be very important in fighting fires in high-rise students’ housing facilities. However, only 9 out of the 20 FSCs received some satisfaction among the respondents in fighting fires in the facilities.

This study offers insight into a rare study area, especially in sub-Saharan Africa. In addition, it grants insight into the occupants’ perspective regarding which FSCs they consider essential and their level of satisfaction with such FSCs in fighting fires in high-rise students’ housing facilities.

Singapore is transforming from a “garden city” to a “city‐in‐a‐garden”. Designing for safety is recognized by researchers and some governments as a best practice in facilitating eventual worker safety within the built environment. The purpose of undertaking this research was to understand and describe the status of safe design for skyrise greenery in Singapore.

A total of 41 rooftop and vertical greenery systems were observed with a focus on access, fall from height, and planting considerations.

Rooftop greenery systems in Singapore were found to be adhering to safe design principles. Vertical and ledge greenery systems, on the other hand, are newer arrangements and were found to be in need of design for safety guidance.

The results add to the body of knowledge in the area of safe design and skyrise greenery and will aid those seeking to understand from a policy and practice perspective.

The purposes of this paper are to implement a spaced repetition algorithm into a learning game, analyze the pros and cons of this implementation and make different considerations about designing the game to make the algorithm work in an optimal way. While games offer a promising way of engaging and motivating learners to deal with a certain topic, repetitions foster immersing this topic sustainably. Those repetitions should be done at sophistically determined intervals to maximize learning outcomes.

The work is implemented as two prototype learning games which use the SM2 algorithm for content selection and repetition scheduling. Based on our findings about user behavior, this study developed an auxiliary algorithm to aid SM2 in the special setting of a learning game. To design the game in a way which supports the spaced repetition approach, this study have analyzed best-practices in this domain and made some considerations for adapting them accordingly.

An auxiliary algorithm is needed to support the usage of common spaced repetition algorithms in mobile learning games. Best-practices in designing those games need to be to suit the spaced repetitions approach.

This paper shows the benefits of combining learning games with the spaced repetition approach and points out specifics in designing spaced repetition based mobile learning games.

While spaced repetitions are already commonly used with other types of learning, it has yet to be implemented in learning games. This study’s approach shows ways to do this and which considerations have to be made.

The purpose of this paper is to explore how functional and appropriateness arguments influence the adoption of modularity principles during the design of a professional service architecture.

Action design research was conducted to examine the design process of a modular service architecture for specialised elderly care by a multi-professional group. Data collection methods included, partly participatory, observations of the interactions between professionals during the design process, interviews and document analysis. Data analysis focussed on the emerging design choices and the arguments underlying them.

A wide range of both functional and appropriateness considerations were enlisted during the design process. The three core modularity principles were adapted to varying degrees. In terms of the design outcome, the interdependencies between the modularity principles necessitated two trade-offs in the modular design. A third trade-off occurred between modularity and the need for professional inference where services were characterised by uncertainty. Appropriateness was achieved through the professionals reframing and translating the abstract modularity concept to reconcile the concept’s functionality with their professional norms, values and established practices.

The study adds to service modularity theory by formulating three trade-offs that are required in translating the core modularity principles into a functional set of design choices for a multi-professional service environment. Moreover, the inherent intertwinedness of the core modularity principles in professional services requires an iterative design process. Finally, the authors saw that the ambiguity present in the service modularity concept can be used to develop a design that is deemed appropriate by professionals.

The purpose of this paper is to construct a typology of a disaster that informs humanitarian-relief supply chain (HRSC) design across the stages of disaster relief.

In addition to an interdisciplinary review of pertinent literature, this paper utilises a typology construction method to propose theoretically and methodologically sound dimensions of disasters.

Whilst semantic arguments surrounding the concept of a “disaster” are ongoing, the authors propose three typologies based upon six dimensions that serve as interdependent variables informing resultant HRSC design considerations. These are speed of onset, time horizon, spatial considerations, affected population needs, perceived probability of occurrence and perceived magnitude of consequence. These combinational and independent relationships of the variables offer insight into key HRSC design-making considerations.

The study improves conceptual knowledge of disasters, distilling the concept to only the dimensions applicable to HRSC design, omitting other applications. The typologies provide empirical cell types based on extant literature, but do not apply the models towards new or future phenomena.

This paper provides HRSC practitioners with normative guidance through a more targeted approach to disaster relief, with a focus on the impacted system and resulting interactions’ correspondence to HRSC design.

This paper provides three typological models of disasters uniquely constructed for HRSC design across the various stages of disaster relief.

This paper aims to synthesize the published literature regarding the impact of environmental design on the improvement of elderly residents’ physical activity.

To provide convergent evidence about the association between facility design/management and physical activity of elderly population, searches were conducted in the PubMed and Google Scholar databases, as well as in specific active living design journals such as Applied Gerontology, Aging and Physical Activity, Housing for the Elderly and Sports Sciences. The inclusion criteria for the final list were the articles that were qualitative, quantitative and mixed-methods studies as well as systematic reviews; written in English; related to the built environmental design; wholly or partially focused on physical activity in elderly population; and published in peer-reviewed journals between 1984 and 2019.

Overall, 30 studies were included in the final list. The results of this review demonstrate that design interventions can raise physical functioning inside and outside of long-term residential facilities. Increasing opportunities for walkable spaces and reducing physical barriers can result in higher levels of physical activity for the elderly population.

This systematic review discloses the design strategies to enhance the level of physical activity by the elderly population based on the findings of the published literature. Overall space layout and accessibility to outdoor walkable spaces were addressed to generally promote the moderate levels of physical activity in elderly population.

The purpose of this paper is to investigate the current practices of the early facilities management (FM) involvement during the design development and review stages (DDRS), and recommend activities aimed at achieving better integration.

A comprehensive literature review was conducted to ascertain the challenges faced by the integrated design team (IDT) in the absence of the facilities managers’ review of design solutions, and underscore the significance of the early involvement of facilities managers during the DDRS. A questionnaire survey was then developed for collecting data on eight aspects of the current practices of early FM involvement during the DDRS. The questionnaire survey was administered to the FM departments of 13 long established, public universities in Saudi Arabia. Ten responses were obtained and analyzed.

The findings suggest that the early involvement of the FM department enhances the operation and maintenance of facilities. This has been measured through reductions in the number of architectural, structural, electrical, plumbing, heating, ventilating and air conditioning defects.

Recommendations were provided to facilitate the process of integrating the practices of two influential stakeholders of building projects. These recommendations encompass the need for maintainability considerations at the early schematic stage, the necessity of direct contact between the two parties and the necessity of facility managers’ increased familiarity of the design stage activities, among other recommendations. In this way, the study promotes the awareness of the significance of integrating FM with the IDT at the DDRS.

This study contributes to the literature and practice by presenting a detailed analysis of the integration process between the FM department and the IDT. Furthermore, the outcomes of the integration between the parties were measured to assess the effectiveness of the collaboration and highlight the possible areas of improvement.

A Summary by Dr. Alexander Klemin of the Papers Presented Before the Fourteenth Meeting of the Institute held at Columbia University, New York, on January 29–31, 1946. AERODYNAMICS IN spite of increased wing loadings, the use of full span wing flaps has been delayed, because of inability to find a suitable aileron. The Development of a Lateral‐Control System for use with Large‐Span Flaps by I. L. Ashkenas (Northrop Aircraft), outlines the various steps in the aerodynamic development of a retractable aileron system well adapted to the full span flap and successfully employed on the Northrop P‐61. Included is a discussion of the basic data used, the design calculations made, and the effect of structural and mechanical considerations. Changes made as a result of preliminary flight tests are discussed and the final flight‐test results are presented. It is concluded that the use of this retractable aileron system has, in addition to the basic advantage of increased flap span, the following desirable control characteristics: (a) favourable yawing moments, (b) low wing‐torsional loads, (c) small pilot forces, even at high speed.

A whole‐systems approach, which seeks to optimize an entire system for multiple benefits, not isolated components for single benefits, is essential to engineering design for radically improved sustainability performance. Based on real‐world applications of whole‐systems design, the Rocky Mountain Institute (RMI) is developing educational case studies to help engineers expand their whole‐systems thinking. The purpose of this paper is to evaluate the effectiveness of these case studies in multiple sections of a first‐year engineering course.

The comprehension of whole‐systems principles by 165 first‐year engineering students at Clemson University was evaluated through surveys and open‐ended questionnaires, before and after introducing the educational case studies.

The pilot study results show that introducing the case studies improves students' consideration of several essential whole‐systems design concepts. The case studies were particularly effective in strengthening student consideration of the clean sheet approach, integrative design, design for multiple benefits, optimization of the entire system, and the possibility of drastic efficiency increases with current technology.

This study was conducted at a single institution and with a fairly homogeneous group of students. These factors should be considered when interpreting the implications of the findings for other groups.

This preliminary research shows that case study examples like these can help increase consideration of the whole‐systems design approach that leads to improved sustainability performance.
