This study aims to develop a web-based tool – LEED Energy Performance Online Submission Tool (LEPOST) to reduce the submission cost of the leadership in energy and environmental design (LEED) application process and facilitate green building design. Lifecycle cost reduction is a major driver for designing green buildings. LEED rating system has been well recognised and widely used in the green building industry. However, certification cost incurred in time and money is often a deterrent for some projects.

LEPOST automatically maps EnergyPlus and eQUEST energy simulation results to the LEED energy performance requirement submission templates using an extensible markup language (XML) data structure. It incorporates the Energy Star Target Finder online engine and current utility data to calculate points required to assess LEED Energy and Atmosphere Prerequisite 2 and Credit 1 automatically.

A comparative case study is conducted using an office building project. The study results show that the tool can reduce the amount of time for the LEED energy performance evaluation and submission process from more than 6 hours to 2 minutes. The total number of manual data entries is reduced from 442 to 20.

Future work includes the update to support LEED V4, the development of a parametric design function that can help design teams perform design alternatives to evaluate energy performance with minimum effort, and the integration with the LEED Online system.

The use of the tool by the building industry may decrease the cost of LEED certification for building owners, developers and design teams by simplifying the submission process.

The overall development framework of LEPOST contributes to the knowledge of the data interoperability in the building sector by demonstrating a viable solution to extract and map digital model information for achieving code and standard compliance purposes.

With the advancement of technology and more attention to environmental issues, building information modeling (BIM) and green building have become two new and growing trends in the construction industry. Therefore, this study proposes a new strategy that integrates BIM and green building rating assessments with an emphasis on Iran Green Building Rating System (IGBRS).

By creating a Revit-IGBRS project template that includes sheets related to all credits, the project compliance with the IGBRS credits and management of submittal documents for certification has been facilitated. Finally, a case study of the materials and resources category of the IGBRS system was performed to validate the BIM-IGBRS application model. All 8 criteria of this category were examined by using Dynamo programming for the Revit sample project.

A practical model for BIM and IGBRS integration is presented, which allows designers to be aware of the IGBRS scores obtained before the project’s construction phase and examine different scenarios for the highest scores. Overall, this study showed that integrating BIM and the Iranian rating system is possible with some constraints, and adding some features to BIM software can promote this integration.

Given that no study has been conducted on the integration of BIM with the Iran Green Building Rating System (IGBRS), the present research investigates utilizing building information modeling to meet the credits requirements of this rating system. The results of this research can be generalized and used in other green rating systems.

Because of global environmental concerns, sustainable design has become a mainstream building design goal in recent years. Sustainable development is even more urgent in the light of global climate change. This paper aims to examine the contributions which building information modelling (BIM) can make to the production of sustainable building designs.

Various research methodologies have been adopted, including literature review, design tool analysis, a case study and structured face‐to‐face interviews. Data collected were synthesized as part of the research process.

BIM is found to be ideally suited to the delivery of information needed for improved design and building performance. Two most significant benefits of BIM for sustainable building design are: integrated project delivery (IPD) and design optimization. However, there are also barriers to adopting BIM for sustainable design.

This paper does not attempt to address all aspects of BIM functionality because the scope of BIM is very great and the resources of this research were limited.

Successful implementation of BIM is able to eliminate the extra cost of design changes during the subsequent phases of construction process. BIM, therefore, is also capable of enhancing the project delivery culture in future.

BIM solutions can contribute to the selection of best solutions to reduce energy and resources consumption. This new technology and the approach also can generate the need of more innovative professionals and job opportunities.

This paper investigates the contribution of BIM to sustainable buildings from the perspective of design performance and improved communication and coordination.

This chapter discusses the profound and influential impact the construction industry has on the national economy, together with the huge negative effect it has on the environment. It argues that by adopting smart and industrialised prefabrication (SAIP), the Australian construction industry, and the construction industry globally, is well positioned to leverage the circular economy to advance future industries with less impact on our natural environment. It discusses aspects of the application of digital technologies, specifically building information modelling, virtualisation, augmented and virtual reality and 3D printing, coupled with reverse logistics as a proponent for advancing the circular economy through smart, digitally enabled, industrialised prefabrication. It further postulates a framework for SAIP for the circular economy.

The purpose of this study is to identify an objective energy performance assessment method in Korea, and to build a building information modelling (BIM) based system that can assess the energy performance of buildings.

The energy performance assessment methods currently used in Korea were first identified via a literature review. A system was then implemented to solve the problem of objectivity. The system was implemented through a data‐based building information model, instead of the existing method of documented two‐dimensional (2D) CAD. In addition, Revit Architecture (a BIM tool), MS Access, and Visual Basic (VB) were used to implement the system. To verify the system's efficiency, it was compared to the existing method by applying both to an actual case (a school facility).

This study found that the issue of subjectivity in the Korean energy performance assessment method may be resolved with a data‐based BIM.

This study presented the BIM‐EPAS to reduce errors and the time needed to conduct an energy performance assessment. In order to follow a realistic approach, the BIM‐EPAS was applied to an actual assessment case, thereby verifying the system's applicability.

Although studies have shown the relevance of building information modeling (BIM) in cost estimating process, efforts at investigating BIM based detailed cost estimating among professional quantity surveyors through quantitative approach are scanty. The purpose of this study is to identify and examine the usage of BIM-based detailed cost estimating software and assesses the drivers to BIM adoption within the Nigerian quantity surveying consulting firms.

A comprehensive literature review, pilot study and questionnaire survey were adopted. The survey targeted both the BIM users and non- BIM users’ quantity surveying consulting firms in Lagos, Nigeria. The data collected were analyzed using frequency, percentage, mean score, standard deviation, Mann–Whitney test and factor analysis.

The study found that 46.58 per cent of quantity surveying consulting firms are aware of BIM and have adopted it for detailed cost estimating, while 49.32 per cent of quantity surveying consulting firms are aware but have not adopted BIM-based detailed cost estimating, and 4.10 per cent of quantity surveying consulting firms are not aware at all. Also, the study identified various BIM-based detailed cost estimating software used in quantity surveying practices and found that Microsoft Excel is often used alongside 3D software, Autodesk QTO, Navisworks, Innovaya Composer and CostX are prevalent BIM software used for detailed cost estimating. In addition, the study identified 21 drivers to the adoption of BIM in quantity surveying practices. The result of factor analysis grouped the 21 identified drivers into five principal factors: improved whole lifecycle/design quality, enhanced decision and visualization, cost and time saving, marketing and support for quantity surveyor tasks and government and client pressure.

This study provides significant insight into the application of BIM to quantity surveying consulting practices, thereby enabling consultant quantity surveyors to make informed decisions to select BIM cost estimating software to suit their practices. Further, the study findings can be useful for individuals’, clients’ and contractors’ quantity surveyors to be fully aware of the opportunities BIM could bring in relation to their service delivery.

Accurate cost estimating, effective cost monitoring and control are essential elements to a construction project success. This study further emphasized the importance of BIM to quantity surveying practices, particularly in the area of the detailed cost estimating.

The purpose of the paper is to marshal the carbon sources, and explore a computational model to calculate the buildings’ carbon emissions by using building information modeling (BIM) techniques. The study aims to integrate the BIM techniques with the carbon emission and energy analysis tools, which can provide a more exact quantification result.

To define the scope of this study, several standards or regulations have been comparatively analyzed. The BIM technique has also been used to establish the computational model of carbon emissions, including the calculation principle, the basic database, and each process of modeling. Finally, a case study is given to test the theoretical study.

The paper provides a quantitative calculation method for the carbon emissions of buildings, and suggests an approach to integrate the BIM techniques with the low carbon research. This allows the quantity of material consumption and carbon emission to be calculated in real time during the whole construction process.

Because of the chosen American database, the calculation results may lack generalizability. Therefore, the approach of establishing a universal database of carbon emission coefficients will be the next key point.

As this research shows, there is a need for an advanced calculation method to evaluate the buildings’ carbon emission exactly by BIM techniques, which also provides a basis to establish the regulation of carbon transaction tax in the future.

This paper fulfils an identified need to calculate the carbon emission during the buildings’ construction stage, so that better decisions can be made to optimize the construction plan and choose the low emission materials properly.

The momentous contribution of innovative technologies has made a significant impact in several sectors globally. However, the construction industry is undoubtedly lagging when it comes to technology usage. Thus, this study aims to explore the various emerging technologies in the construction industry while noticing stakeholders’ challenges and strategies in its use.

The study used a pragmatism research philosophy together with a quantitative research strategy in determining emerging technologies in the construction industry while noticing stakeholder challenges and strategies. Data were obtained from a total of 80 construction stakeholders through a structured questionnaire survey. The analysis was done with descriptive statistics using mean score ranking and a one-sample t-test.

Each emerging technology challenge was analysed and compared to see how pressing the challenges were as well as the aligned strategies. A key indication of this study is that the familiarity of the various emerging technologies was based on how many occasions one had an encounter with the technology.

The discussion’s findings contribute to a better knowledge to construction stakeholders on the challenges and strategies for rising technology adoption and implementation competencies.

The study reckoned stakeholders’ challenges on the emerging technologies in the construction industry context and recommended strategies to balloon the adoption of these emerging technologies in a developing country setting.

Building information modelling (BIM) adoption is vital to the productivity and competitive nature of the construction sector. However, BIM adoptions have not been generally embraced by many architecture, engineering and construction (AEC) firms, particularly in developing countries. Moreover, studies that investigate the important drivers to BIM adoptions among construction professionals through quantitative approach are limited. The purpose of this study is to address the aforementioned gap.

This study involves a literature review, a pilot study and a questionnaire survey. The primary data were carried out using structured questionnaires distributed to four different BIM adopter AEC firms. These comprised architectural firms, facility management firms, quantity surveying firms and structural engineering firms in Lagos, Nigeria. Data obtained were analysed using mean score, standard deviation, Kruskal–Wallis test and factor analysis.

The study identified 23 drivers to BIM adoption, and the relative importance of the identified drivers was gauged from each selected BIM adopter AEC firm category. The result of the Kruskal–Wallis test showed that there is no statistically significant difference in the perceptions of the four selected AEC firms in the mean ranking of the identified 23 drivers to BIM adoption. The findings from factor analysis categorized the identified drivers into two major factors to include cost and time savings, improved communication, and BIM awareness and government supports.

The study empirically identifies important drivers to BIM adoption that will be useful for construction stakeholders to formulate strategies to adopt the full implementation of BIM in the AEC firms of Nigeria and other developing countries. Also, this study is important as it identifies, analyses and compares the drivers to BIM adoptions from four different AEC firms, thereby providing robust and more reliable findings.

The study findings will provide information to policymakers and construction stakeholders to make policy recommendations that are capable of positively influencing the widespread adoption of BIM in AEC firms in particular and the construction industry at large. This study is important because the studies that comparatively and empirically analyzed BIM drivers in AEC firms are rare, particularly in developing countries. Hence, this study could be used to benchmark future studies in developing countries.
