ABSTRACT The literature on the impact of Total Quality Management (TQM) on Design and Build (D&B) projects is scarce and this study fulfills the research gap by assessing the impact of TQM and its elements on D&B projects. The study used a mixed approach comprising a series of expert interviews and a questionnaire survey. Manual content analysis was used to analyze the collected interview data. The interview findings revealed that TQM could improve the quality of a D&B project at five stages of the project. The quantitative analysis of the interview findings was used to assess the significance of TQM in construction, importance of TQM elements in D&B projects, and suitability of TQM and its elements for D&B projects. At briefing, and tender documentation and action stages, TQM is moderately suitable for enhancing D&B project quality, while at concept design and design development, detail design and technical information, and construction and handing over stages, TQM is highly suitable for enhancing D&B project quality. A heatmap was used to present the rankings of TQM elements in D&B project stages with regard to their importance.

ABSTRACT Modern buildings are managed by the BMS (Building Management System), a supervisory system that controls its mechanical and electrical devices. The automatic detection of faults and malfunctions plays a crucial role in the monitoring and control processes of electrical devices located in a smart building. The integration of this functionality within a BMS allows to improve the consistency and the effectiveness of the control network and to recognize and report in real-time the system’s malfunctioning. The research focuses on the definition of Fault Detection procedures to verify the successful implementation of sequential commands given by control and supervisory system. The authors realize a tool to control and manage in real-time the data coming from the sensors to verify the effective implementation of a command. The procedure is based on the following important assumption – we must be able to associate the trend of a given reference magnitude with each command. By monitoring the magnitude’s status and comparing them with default threshold values, the algorithms determine the command execution. Authors apply the proposed strategies on the F40 building, located in the ENEA R.C. ‘La Casaccia’, to detect faults and anomalies that can be traced to probable cyber intrusion or devices malfunctioning.

ABSTRACT Adaptive building envelopes can dynamically adapt to environmental changes to improve thermal building performance. To predict the performance of design proposals with adaptive building envelopes, Building Performance Simulation (BPS) tools can be employed. However, one shortcoming of existing tools is their limited extensibility, which implies that accurately predicting adaptive building envelope performance remains a challenge and requires ad hoc approaches. This challenge has made practitioners reticent in considering adaptive building envelopes, which in turn has led to a slow uptake of them in the built environment. This study seeks to advance the understanding of the limitations of adaptive building envelope simulation in current design practice and to suggest implications for future tool developments. To this aim, the study adopts a user-centred perspective through interviews with experts in the field. Findings suggest that current BPS tools hinder the reliable prediction of adaptive building envelope performance, as accurately representing the level of detail of the building envelope is challenging. The subsequent workarounds applied are either time- and cost-intensive or do not consider the dynamic building envelope components. More flexible modelling approaches that allow for rapid prototyping and easy integration are required to enable designers to take full advantage of adaptive building envelopes.

ABSTRACT The proactive management of a design can prevent design errors. Design changes can be mitigated by using Augmented Reality (AR) prototype digital models. However, the use of these models in construction is still in its infancy. Thus, this study assessed how AR could be used to overcome traditional pre-contract design communication related issues in construction. The study used a qualitative approach. The data required were collected through interviews conducted with experts in the fields of construction and information technology. Manual content analysis was used to analyse the collected empirical data. The study revealed that design communication issues could be related to architectural design, structural design, service design, and design collaboration. AR toolkit models, 360-degree model visualisation, walkthroughs, model registration, clash detection, and digital information overlays would minimise design communication issues, while AR features would enable design knowledge acquisition and negotiation. However, in construction, technical and social challenges are found to hinder AR implementation.

ABSTRACT Although urbanization can increase the prosperity and development of the urbanized communities, the planning, management and governance of these areas is often a struggle resulting in incomplete infrastructure, precarious urban settlements and environmental issues. This study, therefore, was focused on exploring the economic implications of urban renewal by identifying the economic factors that affect the planning and delivery of the associated projects. The study adopted an interpretive stance and the research strategies used were a survey and three case studies. A pilot study was first done and it was followed by case studies. The cases were selected using judgmental sampling and represented the subsystems of urban renewal. The data collected using semi-structured interviews were analysed by comparing with a pattern of impacts developed using literature findings. The study identified the strengths, weaknesses and the areas that can be improved in urban renewal proposals. The findings including were identified under four categories: regional economy, demography, real estate market and transportation economy. The weaknesses of the projects and the strategies that can mitigate them were also identified. A framework that can be used to screen and select new urban renewal proposals was finally developed based on the findings of the study.

The Journal is international and this issue contains papers from Australia, The Netherlands, Sri Lanka and Sweden. It is vital that our knowledge base is universal so that we learn and share our research and experiences. The work of the United Nations (UN) and the World Health Organization is pivotal in this respect. Our knowledge sharing has to transcend any political barriers there may be. Illankoon Chethana (she is from Sri Lanka but not connected to the Sri Lankan researchers I write about later) and her team describe how they developed a scoring model to ensure that the UN Sustainable Development Goals (SDGs) are achieved in practice. The U.S.A. established the Leadership in Energy and Environmental Design (LEED) as a credit system to achieve sustainability in design, and version 3 of this was used to study the interlinks between SDGs and LEED credits. A Comprehensive Contribution to Development was developed as a baseline guide to effect SDGs in practice. Professor Philomena Bluyssen heads the research in the Faculty of Architecture and the Built Environment at the University of Technology in Delft. Her team contributes two papers in this issue: both concerned with environmental conditions in school classrooms and their effect on children. The questionnaire survey of 1145 children and teachers showed that noise and smell were significant issues. Pupils asked teachers to open or close windows, but this alone did not necessarily satisfy the various perceptions the children had about their environment. Individual perceptions vary widely, and their complexity can only be fully solved by using systems that offer the individual control of their immediate surrounding conditions so each person has a personal environmental hub. The other study with 335 primary school children was carried out in an air quality test chamber. Stuffy conditions in rooms are often reported and are associated with stale or smelly air. Using a smell bar – reminiscent of the research by Fanger in 1970–2000 – pupils could rank different sources of smells. You sniff the bouquet of a wine before tasting it and so here sniff the air around different sources like various materials, for example, that you are going to breathe in.

ABSTRACT Much research from different fields has explored the crime-space relationship for different crime types with various study units. However, empirical studies in the diverse urban environments get conflict results that support the two contrary planning paradigms, ‘open’ and ‘closed’ solutions. Through a case study in one prosperous city in China, this research tries to detect the relationship between neighbourhood permeability and the burglary distribution pattern with the study unit of neighbourhood committees. This study focuses on three types of permeability, namely socio-economic, physical, and spatial ones. Our findings show that neighbourhoods with generally lower physical or spatial permeability allowing fewer people to enter or pass by are associate with burglary clustering. Socio-economic barriers offer a positive impact on burglary prevention. Nevertheless, the relationship between permeability and crime distribution is not geographically uniform over the whole city. A suggestion for future research is outlined in the conclusion.

ABSTRACT Application of green adaptive reuse (GAR) is considered to be difficult and lacks the attention in the field of research. The potential of implementing GAR has become uncertain since the way of implementing specific practices is still unknown when the context is different. In Sri Lanka, building professionals are reluctant to use GAR approach due to various obstacles. Specially, due to the scarcity of land, high energy consumption and costs, most of the existing abandoned buildings in Sri Lanka are demolished despite the significant benefits of GAR of buildings. Thus, this research is aimed to develop a framework that could facilitate the implemention of GAR for existing buildings in Sri Lanka. A qualitative research approach was followed for this research with semi-structured interviews. The findings were analyzed using the content analysis method. Significant factors for the implementation of GAR approach were identified mainly under seven criteria including physical, economical, functional, technological, social, legal and political. Further, barriers and strategies for the implementation of GAR for existing buildings in Sri Lanka were revealed. Based on the findings, a framework was developed as a guidance for the implementation of GAR for existing buildings in Sri Lanka which was the key outcome of this study.

ABSTRACT Despite the potential energy savings of automatic lighting control in office buildings, findings show disappointing performance due to poor usability. To explore solutions with a potential to improve user satisfaction with these systems, an iterative user-centered design was done to propose personalized system behavior and an easy-to-use user interface (UI) for total light management (TLM). The steps included defining the semi-automatic system behavior that implicitly derives user lighting preferences from user interaction with the system. Four control options were evaluated in an expert review. Based on the received feedback a redesigned UI was subsequently evaluated as part of the TLM system in a Wizard-of-Oz study. The results showed that the UI offering direct control of lighting dimming level and the position of the blinds offered higher level of usability than the UI with indirect control in which a user defines the desired illuminance from a combination of artificial lighting and daylight.

Four control options were evaluated in an expert review. Based on the received feedback a redesigned UI was subsequently evaluated as part of the TLM system in a Wizard-of-Oz study. The results showed that the UI offering direct control of lighting dimming level and the position of the blinds offered higher level of usability than the UI with indirect control in which a user defines the desired illuminance from a combination of artificial lighting and daylight.","PeriodicalId":45828,"journal":{"name":"Intelligent Buildings International","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/17508975.2021.1902258","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44982964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT The built environment industry is facing a revolution of new digital technologies, all purporting to deliver previously unrealised value and services. However, the process for implementing these new technologies is still immature, often resulting in high-risk and high-cost implementation methodologies. In this paper, a state of the nation analysis is carried out to determine the militating factors for technology implementation within the built environment, and a new alternative non-technical platform methodology is proposed. This methodology proposes a greater focus on the use of proof-of-concepts, governance processes and regular evaluations to ensure new technologies can be implemented into buildings and cities to provide value in the short-, medium- and long-term.
