Journal article (peer-reviewed)abstract
- Purpose: This paper explores the quality and flow of facade product information and the capabilities for avoiding the risk of facade fires early in the design process. Design/methodology/approach: A qualitative case study using the process tracing method is conducted in two stages. First, a thematic analysis of reports and literature identified two categories for the problems that caused fast fire spread across the Grenfell Tower facade. This enabled classifying the identified problems into four stages of a facade life cycle: product design and manufacturing, procurement, facade design and construction. Second, the capabilities for avoiding the problems were explored by conducting in-depth interviews with 18 experts in nine countries, analyzing design processes and designers' expertise and examining the usability of three digital interfaces in providing required information for designing fire-safe facades. Findings: The results show fundamental flaws in the quality of facade product information and usability of digital interfaces concerning fire safety. These flaws, fragmented design processes and overreliance on other specialists increase the risk of design defects that cause fast fire spread across facades. Practical implications: The findings have implications for standardization of building product information, digitalization in industrialized construction and facade design management. Originality/value: This research adds to the body of knowledge on sustainability in the built environment. It is the first study to highlight the fundamental problem of facade product information, which requires urgent attention in the rapid transition toward digital and industrialized construction. © 2022, Soheila Bahrami and Davood Zeinali.

Embracing BIM in its totality: a Total BIM case study
- 2024
-
In: Smart and Sustainable Built Environment. - 2046-6102 .- 2046-6099. ; 13:3, s. 512-531
-
Journal article (peer-reviewed)abstract
- Purpose: Building information modeling (BIM) is mostly limited to the design phase where two parallel processes exist, i.e. creating 2D-drawings and BIM. Towards the end of the design process, BIM becomes obsolete as focus shifts to producing static 2D-drawings, which leads to a lack of trust in BIM. In Scandinavia, a concept known as Total BIM has emerged, which is a novel “all-in” approach where BIM is the single source of information throughout the project. This paper's purpose is to investigate the overall concept and holistic approach of a Total BIM project to support implementation and strategy work connected to BIM. Design/methodology/approach: Qualitative data were collected through eight semi-structured interviews with digitalization leaders from the case study project. Findings were analyzed using a holistic framework to BIM implementation. Findings: The Total BIM concept was contingent on the strong interdependences between commonly found isolated BIM uses. Four main success factors were identified, production-oriented BIM as the main contractual and legally binding construction document, cloud-based model management, user-friendly on-site mobile BIM software and strong leadership. Originality/value: A unique case is studied where BIM is used throughout all project phases as a single source of information and communication platform. No 2D paper drawings were used on-site and the Total BIM case study highlights the importance of a new digitalized construction process.

Energy and architectural consequences of Swedish building code
- 2016
-
In: Smart and Sustainable Built Environment. - : Emerald. - 2046-6099 .- 2046-6102. ; 5:2, s. 125-142
-
Journal article (peer-reviewed)abstract
- Purpose: The purpose of this paper is to propose building code changes that would benefit both architectural design and the potential of achieving nearly zero energy goals by analyzing the architectural implications of the energy system boundaries within the Swedish code.Design/methodology/approach: The analysis is driven by three questions that relate the national implementation of EU directive on nearly zero energy 2020 to the premises set out in the guidelines for revising the Swedish building code aiming at a performance-based regulation. A crucial part of the research is a comparative analysis of the design implications of the code to research findings in scientific articles on near-zero energy or low-energy design.Findings: The energy system boundaries in the Swedish code are steering the architectural design and energy consequences of offices towards using less heat but more electricity. The energy section is also limiting the architectural design choices by ignoring the positive energy aspects of daylight. A proposal of a new comprehensive energy section taking all architectural design related energy aspects into account is presented, in order to support design of nearly zero energy buildings.Practical implications: A building code that relates the energy system boundaries to form will help integrated design choices that are more likely to support the strive towards nearly zero energy buildings.Originality/value: The paper reveals the design implication of the Swedish energy section to be counterproductive regarding energy efficiency as well as limiting architectural design choices.

Augmenting the cities’ and metropolitan regional demands for mega rail infrastructure : the application of SWOT and factor analysis
- 2024
-
In: Smart and Sustainable Built Environment. - : Emerald Group Publishing Limited. - 2046-6099 .- 2046-6102.
-
Journal article (peer-reviewed)abstract
- Purpose: In successfully meeting city and metropolitan growth, sustainable development is compulsory. Sustainability is a must-focus for any project, particularly for large and mega rail infrastructure. This paper aims to investigate to what degree social, environmental and economic factors influence the government when planning sustainable rail infrastructure projects. To respond to such a matter, this paper focuses on two Australian mega-rail projects: the South West Rail Link (SWRL) and the Mernda Rail Extension (MRE). Design/methodology/approach: As the basis of an experimental evaluation framework strengths, weaknesses, opportunities and threats (SWOT) and factor analysis were used. These two methods were specifically selected as comparative tools for SWRL and SWRL projects, to measure their overall sustainability effect. Findings: Using factor analysis, in the MRE, the factors of network capacity, accessibility, employment and urban planning were seen frequently throughout the case study. However, politics and economic growth had lower frequencies throughout this case study. This difference between the high-weighted factors is likely a key element that determined the SWRL to be more sustainable than the MRE. The SWOT analysis showed the strengths the MRE had over the SWRL such as resource use and waste management, and natural habitat preservation. These two analyses have shown that overall, calculating the sustainability levels of a project can be subjective, based on the conditions surrounding various analysis techniques. Originality/value: This paper first introduces SWRL and MRE projects followed by a discussion about their overall sustainable development. Both projects go beyond the traditional megaprojects' goal of improving economic growth by developing and enhancing infrastructure. Globally, for such projects, sustainability measures are now considered alongside the goal of economic growth. Second, SWOT and factor analysis are undertaken to further evaluate the complexity of such projects. This includes their overall sustainable development vision alignment with environmental, economic and social factors.

-
Journal article (peer-reviewed)abstract
- Purpose – The noise and dust particles caused by the construction transport are by most stakeholders experienced as disturbing. The purpose of this study is to explore how sonification can support visualization in construction planning to decrease construction transport disturbances.Design/methodology/approach – This paper presents an interdisciplinary research project, combining research on construction logistics, internet of things and sonification. First, a data recording device, including sound, particle, temperature and humidity sensors, was implemented and deployed in a development project. Second, the collected data were used in a sonification design, which was, third, evaluated with potential users.Findings – The results showed that the low-cost sensors used could capture “good enough” data, and that the use of sonification for representing these data is interesting and a possible useful tool in urban and construction transport planning.Research limitations/implications – There is a need to further evolve the sonification design and better communicate the aim of the sounds used to potential users. Further testing is also needed.Practical implications – This study introduces new ideas of how to support visualization with sonification planning the construction work and its impact on the vicinity of the site. Currently, urban planning and construction planning focus on visualizing the final result, with little focus on how to handle disturbances during the construction process.Originality/value – Showing the potentials of using low-cost sensor data in sonification, and using sonification together with visualization, is the result of a novel interdisciplinary research area combination.

Tree agency and urban forest governance
- 2016
-
In: Smart and Sustainable Built Environment. - 2046-6099. ; 5, s. 176-188
-
Journal article (peer-reviewed)abstract
- Purpose - The role of urban forests and urban trees in creating vibrant and resilient cities is widely recognised. Urban forest governance as the strategic decision and rule making for urban tree resources is no longer solely the domain of governmental actors, but occurs rather often as network governance also involving businesses and civic society. However, governance theory usually does not consider the role of non-human agency, which can be considered problematic due to, for example, the important role of urban trees in place making. The purpose of this paper is to provide further insight into the importance of considering tree agency in governance.Design/methodology/approach - Taking an environmental governance and actor network theory perspective, the paper presents a critical view of current urban forest governance, extending the perspective to include not only a wide range of human actors, but also trees as important non-human actors.Findings - Urban forest governance has become more complex and involves a greater range of actors and actor networks. However, the agency of trees in urban forest governance is seldom well developed. Trees, in close association with local residents, create places, something which needs to be better recognised in governance. Case studies show that this type of non-reflexive agency of urban trees often has emerged in the case of acute threats to urban trees or woodlands. New approaches such as those of biophilic urbanism and biocultural diversity can assist with better integration of tree agency in governance.Originality/value - Urban forest governance is an emerging field of research which has seldom addressed tree agency. Thus the perspective on urban forest governance is enriched, beyond the dominant post-neoliberal and anthropocentric perspective.
