Purpose This study explores the utilization of simulation tools for building performance assessments among design professionals in Ghana. Design/methodology/approach A quantitative approach was used to obtain responses from 104 design professionals in Ghana through a structured questionnaire. The questionnaire was generated through a critical review of the related literature on the subject matter. Data from respondents were analyzed through descriptive and inferential statistics. Findings Results from the analysis indicated that design professionals in Ghana possessed a low level of awareness of the simulation tools used for building performance assessments. Subsequently, the findings also revealed that the design professionals' level of usage of the simulation tools was low. Practical implications Practically, the establishment of this study informs design stakeholders, educational institutions and researchers in Ghana. For design professionals, these findings will focus on enhancing their use of simulation tools for evaluating building performance in Ghana. For educational institutions, these findings will enable them to implement the necessary strategies for incorporating the concept of building performance simulation into their curriculum in order to boost awareness and utilization. Finally, researchers will also use the study's findings to identify any research gaps for future studies. Originality/value The findings from this study pioneer knowledge on an under-investigated topic within the Ghanaian construction industry. It also provides insight into the developing state-of-the-art technology employed in the built environment.

PurposeThe effects of dust exposure in buildings and its health and comfort consequences continue to concern occupants, particularly those who spend most of their time indoors. This study examines the influence of building opening characteristics on surface dust loading in indoor environments to determine the dust particles' impact on different opening configurations.Design/methodology/approachIndoor Harmattan dust surface loading data were collected from Maiduguri, Northeastern Nigeria, using model rooms with six different window configurations. A simple mathematical relationship was employed to assess surface dust loading characteristics in the model rooms. The study measured dust thrice between December and February for three days (72 h). The results were analyzed using descriptive statistics.FindingsThe results determined the highest average surface dust loading of 12.03 g/m2 in the room with awning windows at an indoor-to-outdoor (I/O) ratio of 0.7. In contrast, the experiment in the room with a closed window recorded the lowest average surface dust loading of 5.24 g/m2 at an I/O ratio of 0.30, which is infiltration. The outcomes further indicate that the average surface dust loading varies with the building opening type and position, as higher surface dust loadings were recorded in locations closer to the openings (doors and windows), reaffirming that the dominant source of the dust particles is outdoors. According to the study, dust incursion due to infiltration accounts for 30% of the outdoor surface loading.Originality/valueThus, Harmattan dust is a serious challenge to the health, productivity and hygiene of building occupants in the study area. The built-environment professionals must use the study's outcome to optimize building openings' designs (shape, size and form) for effective indoor dust control.

PurposeThis study examines the underlying relationships between the critical factors of building information modeling (BIM) implementation and the factors' groupings among architecture, engineering and construction (AEC) organizations in Saudi Arabia. The objectives of the study are to (1) identify the critical factors for BIM implementation, (2) analyze the interrelationships between the critical factors and (3) compare the critical factors between the different organizational characteristics.Design/methodology/approachFirst, potential factors were identified through a systematic literature review and interviews with AEC professionals. Then, a questionnaire survey was sent to AEC professionals and the collected data were analyzed using the following techniques and tests: mean score ranking, standard deviation, normalized value, factor analysis (FA), analysis of variance (ANOVA) and post-hoc Tukey test.FindingsThe analyses show that 14 factors are critical for BIM implementation in Saudi Arabia. The top critical factors include the existence of standard contracts on data security and user confidentiality, consistent views on BIM among stakeholders and the availability of guidelines for implementing BIM. Of the 14 critical factors, 9 can be grouped into 4 underlying factors: environmental, governmental, legal and organizational. The analysis shows that the criticality of the most critical factors grouped by the FA varies between different levels of BIM competency. Finally, the presence of public–private partnerships (PPPs) in realizing BIM projects is a new and emerging critical factor for BIM implementation in Saudi Arabia.Originality/valueThis study differs from prior works on BIM implementation in Saudi Arabia by using FA to explore the underlying relationships among factors of BIM implementation and the factors' groupings. Based on the FA results, a roadmap for implementing the BIM was developed. These findings will help to purposefully and efficiently customize BIM implementation strategies and initiatives to ensure successful BIM implementation in Saudi Arabia.

PurposeUnderstanding the technical and socioeconomic dimensions to resilience is core to making a business case for property-level flood risk adaptation. The study investigates the socioeconomic factors that impact the technical dimensions to property-level flood risk adaptation, and whether there is a typology of households adopting similar adaptation measures in Port Harcourt.Design/methodology/approachExploratory and inferential statistical analysis of data collated from 407 questionnaires was carried out. Using chi-square analysis, significant bivariate associations were sought between the level of uptake of different categories of property level adaptation and the socioeconomic characteristics of households. A two-step cluster analysis was used to explore discernible patterns of households implementing similar adaptation measures. Logistic regression analysis was further used to evaluate the extent to which socioeconomic parameters impact residents' willingness to undertake adaptation measures given the option of relocation.FindingsThe chi-square analysis highlighted a lack of significant association between some socioeconomic parameters and the uptake of individual adaptation measures. The regression analysis however showed that the socioeconomic parameters exert varying degrees of influence on the residents' willingness to undertake adaptation measures. Two homogeneous groups of residents with similar socioeconomic characteristics were identified via the cluster analysis but did not translate into strongly discernible adaptation differences/patterns.Practical implicationsThe study shows that although socioeconomic parameters to some extent underlie the technical dimensions to flood resilience, there is no distinctive typology of households in Port Harcourt adopting a similar combination of measures.Originality/valueThe study offers insights into understanding property-level flood risk adaptation responses within the context of the developing world.

PurposeIn the UK, responses to intense weather events regarding national and regional level perils include the support of a General Insurance policy at the address level as part of private residential and other insurance policies covering the key risks of flooding, subsidence and windstorm. In respect of the subsidence peril, dry summers can lead to many thousands of properties on shrinkable clay soils suffering differential downward movement as water is abstracted from the soil by vegetation. These events are forecast to increase in frequency and severity due to climate change, with costs for a dry event year of more than £500m to UK insurers. Assessing the character of these event years can inform government, local government, insurers and their agents as to the typical characteristics of an event year and its impacts. The purpose of this paper is to provide a comprehensive overview of the 2018 UK subsidence event year as it relates to trees and low rise buildings.Design/methodology/approachThe research material is taken from claims that originated within the period commencing in the Summer of 2018, which in the UK was dry and with high levels of claim notification, and is from the private database of Property Risk Inspection Limited, one of the largest UK specialist subsidence claims handling businesses.FindingsThe data clearly illustrates the wide range of vegetative species causing or contributing to claims in the UK, their age ranges, sizes and conditions, management options and the range of land uses and statutory controls that exist in relation to title and other boundaries.Originality/valueThere have been various small-scale studies looking at individual cases of subsidence and the impacts of vegetation, but there have been no detailed investigations of large-scale claims-driven events such as the 2018 surge. The importance of this population-level investigation will only increase given the modelling for increased hot and dry summers over the coming decades.

PurposeUsing Nigeria, as a point of reference, this study aims to explore the applicability of climatic variables as analytically valid factors for conceptual cost estimation. This is in view of the vastness and topographical alignment of Nigeria's landmass, which makes it a country of extreme climatic variability from north to south. As construction costs in Nigeria, similarly, tend to show a north-south alignment, the study's objective is to establish cost-estimating relationships (CERs) between the variability of climatic elements and the variance in construction cost, to arouse interest in the concept.Design/methodology/approachDeploying correlation analysis and multiple regression analysis, significant associations/relationships between meteorological variables and building cost for selected locations, following a North-South transect of the major climatic zones, are sought, to explain climate-induced construction cost variance. Validation of the regression model was carried out using variance analysis and the Mean Absolute Percentage Error of a different dataset.FindingsClimatic indices of atmospheric moisture exhibited strong direct and partial correlations with construction costs, while sunshine hours and temperature were inversely correlated. The study further establishes statistically significant CERs between climatic variables and building cost in Nigeria, which accounted for 47.9% of the variance in construction cost across the climatic zones.Practical implicationsThe study outcome provides a statistically valid platform for the development of more elaborate analytical costing models, for prototype buildings to be cited in disparate climatic settings.Originality/valueThis study establishes the statistical validity of climatic variables in constituting CERs for predicting construction costs in disparate climatic settings.

PurposeSustainability transformation in the construction industry is vital for the attainment of sustainable development goals. While conventional construction has been at the expense of social and economic sustainability, sustainable construction can enhance environmental, social and economic outcomes for the construction industry and society at large. However, the industry struggles with new initiates because its stakeholders are products of unique institutions which shape their decisions and intentions to adopt new practices. This study assessed the institutional pressures that influence the adoption of sustainable construction to enhance our understanding of other factors that can promote and accelerate the adoption of sustainable construction.Design/methodology/approachThe study adopted a quantitative research design with the use of online questionnaires to elicit information from construction professionals in South Africa. Descriptive statistics of frequencies, mean and standard deviation were used to analyse the data obtained from the survey. Linear regression was also used to assess the influence of institutional pressures on the adoption of sustainable construction.FindingsMimetic pressures were found to have a significant influence on the adoption of sustainable construction. The decision to adopt sustainable construction was based on the sustainability actions of industry leaders (mimetic pressure). Normative and coercive pressures had no significant influence on the adoption of sustainable construction.Practical implicationsMimetic pressure from competitors and normative pressures is already exerting some pressure on stakeholders to adopt sustainable construction. However, there cannot be a long-term commitment that will yield the needed sustainability transformations without additional normative pressure from learned societies and coercive pressure from the government. As one of the pioneering works from the global south, this study provides empirical validations of the influence of institutional pressures on the adoption of sustainable construction. It also enhances understanding of how institutional pressures from the social context can promote and accelerate the adoption of sustainable construction.Originality/valueThe findings present one of the pioneering efforts to empirically validate the influence of institutional pressures on the adoption of sustainable construction.

PurposeThis study examines the level of awareness and usage of game elements among construction professionals with a view to promoting the usage of gamification tools for the effective and efficient delivery of construction projects.Design/methodology/approachData were obtained from construction professionals including architects, builders, engineers and quantity surveyors. Retrieved data were analyzed using several statistical tools such as percentages, frequencies, mean item scores and exploratory factor analyses.FindingsThe analysis revealed that progress bars, certificates and bonuses are the significant game elements adopted by professionals, but there is a low awareness of elements such as avatars and badges.Practical implicationsThere is a salient need for construction stakeholders' awareness of the importance of gamification and game elements as a key digital tool for the delivery of construction projects. The findings of this study make a case for stakeholders, professional bodies and government agencies to embrace and implement gamification practices in the construction sector.Originality/valueThis study is the first conducted in Nigeria to examine the level of awareness and usage of game elements among construction professionals. The findings of this study will provide a reference point for researchers who will undertake studies relating to the concept of gamification in the construction industry context.

PurposeResidential buildings in Greece constitute an important portion of the existing building stock. Furthermore, most of these buildings were built prior to the first Thermal Insulation Code of 1981. The article focuses on existing, typical residences built after 1920, which are found mostly in suburban areas and settlements all around Greece. The purpose of the research is to evaluate the effect of simple bioclimatic interventions focused on the improvement of their diurnal, inter-seasonal and annual thermal performance.Design/methodology/approachThe applied strategies include application of thermal insulation in the building shell and openings, passive solar systems for the heating period and shading and natural ventilation for the summer period. The effect of the strategies is analysed with the use of building energy analysis. The simulation method was selected because it provides the possibility of parametric analysis and comparisons for different proposals in different orientations.FindingsThe results show that the increased thermal mass of the construction is the most decisive parameter of the thermal behaviour throughout the year.Research limitations/implicationsThe typical residences under investigation are often found in urban and/or suburban surroundings. These mostly refer to free-standing buildings situated, which, in many cases, do not have the disadvantages and limitations that the geometrical characteristics of densely built urban locations impose on incident solar radiation (e.g. overshadowing during the winter) and air circulation (e.g. reduce natural ventilation during the summer). Nevertheless, even in these cases, the surrounding built environment may also have relevant negative effects, which were not taken under consideration and could be included in further, future research that will include the effect of various orientations, as well as of neighbouring buildings.Practical implicationsExisting residences built prior to the first Thermal Insulation Code (1981) form an important part of the building stock. Consequently their energy upgrade could contribute to significant conventional energy savings for heating and cooling, along with the inter-seasonal improvement of interior thermal comfort conditions.Social implicationsThe proposed interventions can improve thermal comfort conditions and lead to a reduction of energy consumption for heating and cooling, which is an important step against energy poverty and the on-going energy crisis.Originality/valueThe proposed interventions only involve the building envelope and are simple with relatively low cost.
