Abstract

Purpose

The aim is to holistically assess the environmental performance of windows and analyse how their design and characteristics contribute to the overall performance of the building/space. This study focuses on the performance of windows in patient rooms hosting less mobile people.

Design/methodology/approach

This study investigates the life cycle environmental impacts of different glazing types, window frames and fire safety doors at the product level. This article also presents a building-integrated environmental analysis of patient rooms that considers the multiple functionalities of windows by incorporating dynamic energy analysis, comfort and daylighting performance with a life cycle assessment (LCA) study.

Findings

The results indicate that the amount of flat glass is the main contributor to the environmental impacts of the glazing units. As for the patient rooms, global warming shows the most significant contribution to the environmental costs, followed by human toxicity, particulate matter formation and eutrophication. The key drivers for these impacts are production processes and operational energy use. This study highlights the significance of evaluating a wide range of criteria for assessing the performance of windows.

Originality/value

An integrated assessment approach is used to investigate the influence of windows on environmental performance by considering the link between window/design parameters and their effects on energy use/costs, daylighting, comfort and environmental impacts. The embodied impacts of different building elements and the influence of various design parameters on environmental performance are assessed and compared. The environmental costs are expressed as an external environmental cost (euro).

Abstract

Purpose

Developing a reliable cost estimate at the early stage of construction projects is challenging due to inadequate project information. Most of the information during this stage is qualitative, posing additional challenges to achieving accurate cost estimates. Additionally, there is a lack of tools that use qualitative project information and forecast the budgets required for project completion. This research, therefore, aims to develop a model for setting project budgets (excluding land) during the pre-conceptual stage of residential buildings, where project information is mainly qualitative.

Design/methodology/approach

Due to the qualitative nature of project information at the pre-conception stage, a natural language processing model, DistilBERT (Distilled Bidirectional Encoder Representations from Transformers), was trained to predict the cost range of residential buildings at the pre-conception stage. The training and evaluation data included 63,899 building permit activity records (2021–2022) from the Victorian State Building Authority, Australia. The input data comprised the project description of each record, which included project location and basic material types (floor, frame, roofing, and external wall).

Findings

This research designed a novel tool for predicting the project budget based on preliminary project information. The model achieved 79% accuracy in classifying residential buildings into three cost_classes ($100,000-$300,000, $300,000-$500,000, $500,000-$1,200,000) and F1-scores of 0.85, 0.73, and 0.74, respectively. Additionally, the results show that the model learnt the contextual relationship between qualitative data like project location and cost.

Research limitations/implications

The current model was developed using data from Victoria state in Australia; hence, it would not return relevant outcomes for other contexts. However, future studies can adopt the methods to develop similar models for their context.

Originality/value

This research is the first to leverage a deep learning model, DistilBERT, for cost estimation at the pre-conception stage using basic project information like location and material types. Therefore, the model would contribute to overcoming data limitations for cost estimation at the pre-conception stage. Residential building stakeholders, like clients, designers, and estimators, can use the model to forecast the project budget at the pre-conception stage to facilitate decision-making.

Abstract

Purpose

This paper aims to propose a robust method for non-rigid point set registration, using the Gaussian mixture model and accommodating non-rigid transformations. The posterior probabilities of the mixture model are determined through the proposed integrated feature divergence.

Design/methodology/approach

The method involves an alternating two-step framework, comprising correspondence estimation and subsequent transformation updating. For correspondence estimation, integrated feature divergences including both global and local features, are coupled with deterministic annealing to address the non-convexity problem of registration. For transformation updating, the expectation-maximization iteration scheme is introduced to iteratively refine correspondence and transformation estimation until convergence.

Findings

The experiments confirm that the proposed registration approach exhibits remarkable robustness on deformation, noise, outliers and occlusion for both 2D and 3D point clouds. Furthermore, the proposed method outperforms existing analogous algorithms in terms of time complexity. Application of stabilizing and securing intermodal containers loaded on ships is performed. The results demonstrate that the proposed registration framework exhibits excellent adaptability for real-scan point clouds, and achieves comparatively superior alignments in a shorter time.

Originality/value

The integrated feature divergence, involving both global and local information of points, is proven to be an effective indicator for measuring the reliability of point correspondences. This inclusion prevents premature convergence, resulting in more robust registration results for our proposed method. Simultaneously, the total operating time is reduced due to a lower number of iterations.

Abstract

Purpose

This paper analyses changes in the activity pattern of Damascus city from late modern era (late Ottoman rule) to the contemporary era. The research objective is to explore the impact of the socio-historical process on the evolving morphological structure of the urban core and to draw implications for post-war reconstruction.

Design/methodology/approach

Space Syntax methodology was employed to trace the historical and morphological changes in the urban core of Damascus. The timeframe was divided into five periods covering the city's socio-political transformation and five maps depicting these periods. Local and global integration measures were used to analyse the changes in the urban core across each period. Normalised angular choice (NACH) measure was used to identify the changes in the city planning system.

Findings

The results revealed that the urban core corresponded to the main streets, which had socio-economic importance across history. However, introducing a new planning system influenced by Western planning ideals led to the creation of multi-morphological patterns. At the city level, the study found that the urban core was more accessible in the preplanned areas, while the organic expansion of the informal settlements was exclusive of the core area. At the local level, some informal settlements showed an intense core. Intelligibility analysis revealed that earlier periods showed considerably higher values, implying declines in the ease of navigation of the city over time.

Research limitations

This study did not account for the political, economic and cultural factors that could shape morphological changes in Damascus. In addition, the study adopted historical reference points to understand the morphological changes, as high-quality geospatial data was not available to monitor the recent post-war situation.

Practical implications

The research findings give a foundation for a more contextualised historical understanding of spatial structure and changes, which can contribute to the post-war reconstruction and redevelopment of Damascus city.

Originality/value

To the best of the authors’ knowledge, this paper is the first to trace historical spatial changes in Damascus from a space syntax approach, weaving together socio-historical and configurational studies. In doing so, it shows how historically informed and spatially aware urban planning and design policies can support policymakers and built environment professionals in planning and redevelopment.

Abstract

Purpose

This study aims to demonstrate what myths of and about science are reproduced in this popular cultural work (movie – “Oppenheimer”). This is done by examining the unconscious hegemonic positions supported by the reproduction of stereotypical and mythical images of science.

Design/methodology/approach

Content/Text Analysis: The conceptual analysis of a cultural text – a film (“Oppenheimer”) – through a theoretical apparatus (B. Latour’s theory).

Findings

The film demonstrates its reproduction of three distinct elements. Firstly, it exhibits classic scientistic clichés pertaining to technoscience. Secondly, it highlights the replication of the individualized monomyth about the (super) hero, leading to the exclusion of the intricate conditions of technoscience’s existence. Lastly, the film aligns with the Californian ideology, as proposed by Barbrook.

Originality/value

The value of the text is twofold: (1) To show that the classical approaches of Bruno Latour are still relevant. (2) To show what hidden premises and myths about technoscience are being propagated through a work of pop culture (the film “Oppenheimer”) and, in effect, to show what kind of influence of cultural hegemony is at work here.

Abstract

Purpose

The paper aims to elaborate on the potential for regeneration of Bagamoyo (Tanzania) through adaptive reuse of its heritage sites. The town was the most important harbour for ivory and slaves of the East-African mainland during the 19th and early 20th century and the colonial capital of German East-Africa between 1885 and 1890. Today, it has 85,000 inhabitants who mainly live in informal settlements while stone town closer to the coast is largely abandoned with its historical buildings in a poor state of conservation.

Design/methodology/approach

The first part of the paper describes the history and heritage of the old stone town Bagamoyo, and how it impacts its identity. Additionally, it summarises the critical reception of the town's role in the application to UNESCO World Heritage for “The Central Slave and Ivory Trade Route”. This, in order to consider the reuse of its heritage sites more as part of a layered regeneration process than of a singular narrative for preservation. The second part presents research-by-design proposals investigating the economic, social and cultural potentialities of three spatial layers: the main street, the coastal strip and the shoreline.

Findings

The identity and therefore also urban regeneration of post-colonial towns such as Bagamoyo is the result of a complex combination of different narratives rather than of a singular one.

Originality/value

Bagamoyo's heritage has been studied as a driver for international tourism linked to slavery but without successful implementation. This study proposes an alternative perspective by investigating its potential for urban regeneration in line with local needs. Developed in the context of a master studio of architectural design, it presents an innovative didactic approach. Moreover, the methodology of research-by-design can be inspirational for other historical towns.

Abstract

Purpose

In response, this study developed a mathematical and computational method, through spatial configurations with justified plan graph (JPG), drawn from Space Syntax to extract essential information of the spatial topology of 13 valuable traditional courtyard houses located in Toon historical city of Iran.

Design/methodology/approach

Historical vernacular housing has always been designed to incorporate and reflect the local lifestyle and cultural conditions. “Courtyard” is a fundamental part of traditional Iranian houses. This traditional building type includes a walled boundary and a complex of open, semi-enclosed and enclosed spaces. This study investigates the traditional houses in Toon historical town. Toon is one of the ancient towns in southeast Iran, including old courtyard houses in its heritage context. The spatial influence of the courtyard contributes to the formation of this famous architectural type.

Findings

The results show the remarkable impact of this space on dominating the plan of traditional Toon houses configuration compared to other spaces in all cases. Furthermore, spatial accessibility has changed over time, and the Safavid period had a higher level of integration and lower level of accessibility (mean i = 7.03) rather than the Qajar period (mean i = 6.34); also, privacy has decreased progressively.

Originality/value

The knowledge of characteristics of this historical architecture needs to be gathered for the preservation and conservation of the built heritage. Hence, the principle behind traditional Iranian courtyards was investigated to recognize the difference between the spatial influence of the courtyard and other spaces and the changes in the courtyard over time.

Abstract

Purpose

Construction activities conducted in urban areas are often a source of significant noise disturbances, which cause psychological and health issues for residents as well as long-term auditory impairments for construction workers. The limited effectiveness of passive noise control measures due to the close proximity of the construction site to surrounding neighborhoods often results in complaints and eventually lawsuits. These can then lead to delays and cost overruns for the construction projects.

Design/methodology/approach

The paper proposes a novel approach to integrating construction noise as an additional dimension into scheduling construction works. To achieve this, a building information model, including the three-dimensional construction site layout object geometry, resource allocation and schedule information, is utilized. The developed method explores further project data that are typically available, such as the assigned equipment to a task, its precise location, and the estimated duration of noisy tasks. This results in a noise prediction model by using noise mapping techniques and suggesting less noisy alternative ways of construction. Finally, noise data obtained from sensors in a case study contribute real values for validating the proposed approach, which can be used later to suggest solutions for noise mitigation.

Findings

The results of this study indicate that the proposed approach can accurately predict construction noise given a few available parameters from digital project planning and sensors installed on a construction site. Proactively integrating construction noise control measures into the planning process has benefits for both residents and construction managers, as it reduces construction noise-related disturbances, prevents unexpected legal issues and ensures the health and well-being of the workforce.

Originality/value

While previous research has concentrated on real-time data collection using sensors, a more effective solution would also involve addressing and mitigating construction noise during the pre-construction work planning phase.

Abstract

Purpose

This paper first aims to examine associations between factors involved in business-to-business complaints management and results (satisfaction and loyalty) and analyses three types of distributors based on their cultural profile (domestic, low context and high context). Second, the paper investigates whether the identified associations remain stable over time.

Design/methodology/approach

Data from a sample of distributors for a manufacturing company were gathered during two periods of time. A factorial analysis of correspondences and a cluster analysis were carried out to visually represent the associations among clients, complaints and results in the associations among clients, complaints and results. The stability over time of these relationships was also analysed by calculating the correlations between the Euclidean distances on the two maps (one per year) and their mobility ratio.

Findings

The authors found significant evidence that clients from different cultures are associated with varying profiles of complaint and different result types and that certain associations remain stable over time.

Originality/value

While many studies have analysed complaint behaviour in business-to-consumer contexts, there is a lack of research from an international business-business relations point of view, leaving questions virtually unexplored. Second, the last phases of supply chain management, specifically complaints management, have been undeveloped, limiting the cultural factor to the general scope of negotiation. In this vein, this paper compares different complaint profiles and results, comparing culturally different customers/distributors. Third, research has mostly referred to a single period, while this paper investigates two different periods of time for the same company (and their distributors) to analyse the relevance of the stability (or not) over time of the associations identified.

Abstract

Purpose

Competitively multipolar international system demands bilateral and multilateral partnerships. Joint innovation signals close partnerships. Regional proximity of Central and Eastern Europe (CEE) to the European Union (EU) defines its research and development objectives. These objectives are additionally subjected to the USA’s geopolitical strategy in this geographical area. Hence, CEE’s limited resources require limited resources make international innovation cooperation. This paper aims to analyse whether and how CEE countries make international innovation cooperation decisions.

Design/methodology/approach

This paper used Organisation for Economic Co-operation and Development (OECD) database of total patent applications filed to the patent cooperation treaty (PCT) with co-applicants from abroad, where co-patents with at least one foreign inventor present a measure of international innovation partnership. A vector autoregression analysis and impulse response function were used to analyse international innovation partnership choices of eight CEE OECD countries for the period 1990–2018.

Findings

Innovation with the EU is of collaborative nature, commonly displaying complementary properties with the rest of the examined innovation partners, while co-patenting with the Russia and China act as substitutes or complements. Co-patenting with Russia is the most versatile, displaying both properties of collaboration and competition. Some countries exhibit complementarity in co-patenting activities with multiple partners. The significance levels of these relationships vary, indicating varying degrees of impact. Overall, these findings highlight the complex dynamics of co-patenting activities and the influence of different partners on countries’ collaborative innovation strategies.

Research limitations/implications

In addition to significant relationships, insignificant relationships as well as those that could bring about greater synergy are flagged in the paper. Those relationships portray possible direction into which national funds could be channelled to incite cooperation between different sectors and countries, especially as innovation partnerships are not always successful and require a long time period to materialise.

Originality/value

By examining bilateral innovation partnerships, this study provides an insight into the strategic political and economic spheres of influence in the CEE region.
