Abstract

The concept of intelligent building is emerging in the contemporary built environment. Intelligent buildings aim to leverage digital technologies and information throughout the building’s life cycle (design, construction, and operation phases) to improve the building’s performance and value. In recent years, academic scholars and industry practitioners have made efforts to articulate the intelligent building concept and identify its components. However, there is still no commonly accepted definition for the term intelligent (or smart) building. Furthermore, the term is used interchangeably with similar terms such as sustainable building and high-performance building. The primary gaps in research are the lack of a holistic and clearly defined list of intelligent building components. This gap limits building stakeholders’ abilities to decide which technologies to implement in their buildings, prove its capabilities and advantages, and improve its performance. In response to the identified gaps, this research conceptualizes intelligent building in comparison with the concept of sustainable building. We identified the key components that each concept entails and conducted a comparative analysis of the identified components. The findings of this research include a categorization of intelligent building’s definitions which helps to conceptualize intelligent building and distinguish it from other similar concepts. In addition, the research team used the developed ontologies for intelligent and sustainable buildings to provide a fundamental overview of the structure of building evaluation systems and their different approaches for determining evaluation criteria. Overall, this study contributes to the body of knowledge by identifying and classifying components of intelligent buildings, which is a prerequisite for intelligent buildings’ evaluation. It also makes a distinction between the concepts of intelligent building and sustainable building in order to determine their context and applications.

Abstract

An increasing number of projects are adopting prefabrication to economize on time, labor, and materials in fixed-position layout operations, such as construction, ship building, and aircraft manufacturing. In such contexts, independent contractor and fabricator make interdependent decisions, which calls for prudent supply chain management because performance relies on coordination between their decisions. Many studies have developed integrated systems and propose various algorithms for scheduling efficiency and reliability. Nevertheless, they pay scant attention to conflicting interests amongst independent partners, which may result in subpar performance not only for the supplier but for the contractor as well. Coordination of conflicting interests has been extensively studied in economics and supply chain management; yet, those studies focus on order-quantity decisions under demand uncertainty for profit maximization, while managers in fixed-position operations are more concerned about delivery decisions under scheduling uncertainty for cost minimization. We consider the case of construction and explore a contractual scheme that aligns the agents' decisions for coordination in a construction supply chain. Specifically, we propose a supplier rebate for coordination: the supplier grants a rebate if the contractor accepts the shipment in accordance with the delivery schedule that the contractor initially chose. We show that the optimal rebate fully coordinates the supply chain to minimize the joint supply chain costs. Thus, both the contractor and supplier benefit from the coordination by negotiating a mutually acceptable way to allocate the savings in joint costs between them. We further show that the rebate motivates the contractor to enhance its work scheduling.

Abstract

Environments, Health, and Safety (EHS) activities are strongly linked to the concept of sustainability in the current construction industry and consequently absorb more financial and managerial attention. One of major obstacles in EHS costing is that most EHS costs are buried in general overhead costs. Therefore, EHS costs lacks transparency, making it hard to allocate EHS costs to relevant construction projects. This paper present a recent study in which a method of activity-based costing (ABC) has been applied to safety costs at a contractor's home office. The list of safety activities, their cost drivers as well as their cost information on one of Korean general contractor is provided. The authors expect that the application of ABC will improve transparency in costing EHS costs as well as allocating EHS costs to projects.

Abstract

Unsanctioned, unscripted, and seemingly “undesirable” activities have long appropriated urban spaces in routine and sometimes unexpected ways, bringing new meanings and unforeseen functions to those places. In the last decade or so, such practices have inspired a growing movement under the banner of DIY and tactical urbanisms. The growing acceptance of these practices creates important openings in the formalized planning systems for greater fexibility and expedient change. Yet, the institutionalization of previously informal and even subversive acts has resulted in concerns regarding co-optation and de-politicization. This special issue seeks to pivot a refocus towards these unsanctioned and unscripted urban activities as a form of counter-hegemonic spatial practices, distinct from its professionalized and institutionalized counterpart. A range of cases is examined here sharing similar characteristics as challenges against the prevailing social and political paradigm. Key findings include the scalability of guerrilla actions, the fuid shift between overt and covert actions, and the linkage between everyday struggles and organized resistance. This special issue is intended to advance our understanding of urban design by situating it in a broader social, economic, and political praxis that encompasses both formal and informal practices performed by a wide variety of individual and collective actors.

Abstract

Early BEH research addressed influences of toxic environmental exposures, zoning laws, building codes, and healthy housing and communities on asthma, injury, violence, healthy and unhealthy food consumption, mental health, social capital, and health inequities.1 Awareness increased regarding the benefits of denser, more walkable, and less automobile-dependent settings, as well as the accessibility, mobility, and livability needs of the growing aging population. Work on automobile dependence, traffic safety, walking and biking, commuting, and sedentary time was primarily driven by the Robert Wood Johnson Foundation's Active Living Research initiative to promote active living via environment, policy, and practice improvements3,4 Research linked specific building and community features to health outcomes, enabling more effective interventions such as appealing stairways, ample sidewalks, and vibrant activity centers.5 The business case for health promoting, walkable places was documented.6 Unintended consequences, including gentrification and displacement, of interventions aimed at improving health among people from racial and ethnic minority groups and of lower incomes were increasingly recognized, resulting in more research focused on how to mitigate these risks.7 The history of structural racism, segregation, redlining, neighborhood disinvestment, health inequities, and disparities in walkability, housing, and green space access was only recently widely acknowledged.8 Numerous books (Table E, available as a supplement to the online version of this article at http://www.ajph.org) and dozens of BEH measures (e.g., walkability [https://www.wal kscore. com], access to parks [https://www.tpl. org/ParkScore], livability [http://www. livabilitylndex.AARP.org], and brain health [https://cognability.isr.umich. edu]) were also published, reflecting the growth and maturation of the field. The effects of these evolving technologies on land use, housing, economic and community development, traffic patterns, transportation planning and infrastructure, air quality, and associated health outcomes require further research and evaluation (Table G, reference 3).10 PRACTICE Professional organizations across disciplines established BEH committees and working groups (Table F, available as a supplement to the online version of this article at http://www.ajph.org), promoting healthy building and community design through conferences, reports, training, and advocacy (e.g., https://www. Health impact assessments (HIAs) were used to consider potential health impacts of proposed projects and programs and identify disproportionately affected populations as well as how to mitigate adverse effects9,11,12 HIAs improved collaboration, amplified community member voices, increased awareness of health issues, and informed decision makers, but the time and resources required to complete HIAs limited their success.12 Cross-disciplinary public health, planning, policy, real estate, architecture, engineering, transportation, and public-private partnership efforts, along with Complete Streets approaches (https://highways.dot.gov/ complete-streets), improved pedestrian infrastructure and safety.

Abstract

In the last few decades, there has been a definitive shift in public support for compact development – characterized by high densities, more multifamily residential use, and effective public transit. The allure of compact development is because, along with sustainability benefits, it offers multiple lifestyle benefits, such as more significant opportunities for socialization and easy access to amenities. Greater possibilities of frequent and longer interpersonal interactions attract residents to such communities. However, given the recent pandemic, it is logical to be concerned about how future public support for compact development may change. This study analyzes data from a national online survey (n = 1100) conducted in the United States toward the end of the COVID-19 pandemic (April 2022). This research aims to assess the relationship between perceived concern for COVID-19 transmission and public support for compact development. The results from SEM analysis suggest that people more concerned about COVID-19 transmission are less supportive of compact development policies. People from areas with higher density and more COVID-19 cases are likely to have greater concern for COVID-19 transmission, which may decrease support for compact development in these areas (mediated relationship). Individuals who rely on news, online media, friends or family for COVID-19 information and single-family residents are also less likely to support compact development. In contrast, while older adults are likely to have higher concern for COVID-19 transmission, they are likely to support compact development. Higher-income households are less likely to be concerned about COVID-19 transmission but are more supportive of compact development. These findings suggest that the perceived threat of disease transmission will likely result in decreased public support for compact development. To ensure continued public support, urban policymakers must allay public fear of virus transmission in compact built environments by incorporating public health measures for controlling virus transmission in compact urban environments.
