IOP Conference Series: Earth and Environmental Science, 2019
The construction industry in Malaysia faces a number of complications in terms of managing project duration and budgeted cost. The recent technology trend has moved the industry towards adoption of Building Information modelling (BIM) as a mean to efficiently plan, design, build, manage and control projects. Since BIM is perceived as a holistic solution for integration of various project attributes, this research has hypothesised that additional objectives such as sustainability and green building design can simultaneously be achieved if appropriate BIM approach is implemented. The main scope of this research is to introduce a framework for integration of Malaysian Green Building Index (GBI) with existing Building Information Modelling (BIM) tools. The proposed GBI-BIM framework is made possible via the introduction of a set of supporting tools such as Revit Green Project Template (RGPT) and GBI Document Assessor that assist designers to automatically analyse and assess 56 out of 10...
New Opportunities of Using Building Information Modelling (BIM) for Green Buildings
2019
Building information modelling (BIM) is a collaborative working process using digital models to support virtual design and construction (VDC) which can streamline project delivery workflow and improve building performance. The use of BIM to provide data for energy performance evaluation and sustainability assessment is known as Green BIM. In recent years, BIM adoption has grown significantly in many countries and cities around the world. BIM-based energy analysis can help project design teams to examine and create optimized energy efficiency. A BIM-based approach to green building can assist professionals in predicting the outcomes of construction to minimize its impact on the environment throughout its life cycle. The Green BIM potentials can be enhanced when useful information and data are collected and provided to facilities managers and building end-users. This research paper will explain the key characteristics of BIM, describe the information requirements and management for su...
EXPECTATIONS, REALITY AND PERSPECTIVES IN USING BIM FOR THE GREEN BUILDING DESIGN
Structural Integrity and Life, 2017
In the late 1970s when first programs for building energy consumption simulation appeared architectural practice was based on paper documentation and 2D drafting programs where considered as the state of the art technologies. The requirement for 3D building models for the computer based energy simulation minimized the use of this technology in everyday practice. With the appearance of the BIM applications that enable creation of the information rich 3D building models everyone expected that this technology can easily provide all data necessary for energy consumption simulation. Today, market is full of different BIM related applications that are advertised as solutions for the green building design. The paper gives an overview of the energy consumption simulation tools and their connection to two BIM applications – ArchiCAD and Revit and demonstrates that recent development of both technologies does not fully meet expectations. The paper indicates means to avoid overoptimistic expectations from software tools that can help designers to achieve better comprehension of the real merits that BIM can bring to green building design. The paper addresses usability of using BIM for sustainable refurbishment. The paper concludes with the analysis of the Semantic Web technologies which can contribute to a better understanding of simulation results, and can provide more information about energy efficiency of the components that are used in BIM applications’ libraries.

Quantifying the environmental impacts and simulating the energy consumption of building’s components at the conceptual design stage are very helpful for designers needing to make decisions related to the selection of the best design alternative that would lead to a more energy efficient building. Building Information Modeling (BIM) offers designers the ability to assess different design alternatives at the conceptual stage of the project so that energy and life cycle assessment (LCA) strategies and systems are attained. This paper proposes an automated model that links BIM, LCA, energy analysis, and lighting simulation tools with green building certification systems. The implementation is within developing plug-ins on BIM tool capable of measuring the environmental impacts (EI) and embodied energy of building components. Using this method, designers will be provided with a new way to visualize and to identify the potential gain or loss of energy for the building as a whole and for e...
Estidama is a mandatory Green Building code in Abu Dhabi by which the compliance of building design is being assessed. This paper examines the current design and assessment approaches for Green Buildings to identify the reasons that lead to delay defects and it investigates a new approach for improvement. The available literature provides a realistic understanding to the problems and shows the road to some potential solutions. The identified problems were mainly attributed to the manual assessment with too much human interference. The piled documents with limited resources left the assessment system too slow to handle the whole projects within the greater Abu Dhabi engendering high risk of the commitment to review mistakes. Therefore, this paper investigates the potentiality of automating several stages via the use of Building Information Modelling (BIM) into the assessment process. Different experienced participants from all aspects within the construction industry were interviewed to contribute to the research. Also, a close question questionnaire was distributed to examine the current practice in Abu Dhabi to compare it with the initial findings. The findings point out significant requirements to adopt BIM in the assessment process, such as the availability of proper contracts form to shape the relationship between BIM parties and the readiness of the current system. Hence, the authors suggest a new model that integrates BIM capabilities within the system to accelerate the process and reduce human involvement.

Due to the arising concern for sustainability in built environment, numerous green building certification and rating systems are available throughout the world including Green Building Index (GBI) and GreenRE which were introduced in Malaysia in 2009 and 2013 respectively. However, the current methods of measuring, analysing and documenting the green building design rely on a number of disjointed processes to meet the discrete requirements for various building systems. The development of Building Information Modelling (BIM) technology has made it easier to get complicated building modelling be digitally constructed, generating all required information to support green building design and assessment throughout various design stages. Thereby the aim of this research is to integrate BIM and green building certification in Malaysia, using GBI as a unique case. Firstly, Green Building Index (GBI) and related guidelines were reviewed. Secondly, functionalities of BIM software (Autodesk Revit) were studied and compared to GBI assessment criteria. Finally a generic BIM-GBI model was developed based on the matchup of GBI credits and the functionality of Revit, focusing on the first category of GBI, which is Energy Efficiency (EE) and holds 35% of total points in GBI. The proposed BIM-GBI (EE) model was preliminarily validated by creating a use case of GBI sub-category EE1. The fundamental contribution of this research will be the unique approach it proposed to fulfil green building certification such as GBI by integrating functionalities of BIM.
Analysis of BIM-Based Digitising of Green Building Index (GBI): Assessment Method
MDPI, 2022
There is currently an increasing demand for Building Information Modelling (BIM) to be integrated into green projects. BIM is able to evaluate green building assessment tools by digitising and assessing buildings during their development stage. In Malaysia, the Green Building Index (GBI) promotes sustainability in the built environment. Six categories of criteria will be assessed in three of the certification stages. This study focuses on how BIM applications can digitise the GBI criteria for GBI processes. It examines BIM uses and tools of each GBI credit and defines the responsibility and role of construction stakeholders in using BIM to examine the assessment methods used for new non-residential building construction based on GBI. The primary method for data collection is the focus group interview which involves the groups of stakeholders involved in a BIM and GBI project. The result of the BIM–GBI assessment method showed that BIM could digitise and assess 25 credits in Design Assessment (DA), which can achieve 55 points of the total 100 points. This study helps stakeholders define the design team and facility manager’s roles to obtain GBI certification and maintain the certification during the building’s operation stage.
The advent of building information modelling (BIM) is revolutionising the conventional practices of the construction industry and has reinforced the impact of the design process on the building project's overall life cycle. The industry is also moving towards sustainability through owners being committed to having green rated buildings and infrastructure. However, green buildings and their rating systems face several obstacles and shortcomings that hinder their sustainability. Several studies have considered BIM for sustainability aspects, but these were not connected directly with such obstacles. This paper is a literature review that links the obstacles and shortcomings faced in green buildings and their associated rating systems with the potential capabilities of BIM. The limitations of BIM in the green building industry was also addressed. The main obstacles and shortcomings faced are high upfront costs and delays, design complexities and documentation requirements, superior performance enhancement requirements, and skewness towards environmental sustainability. The paper was written from a realisation that a more consolidated future research direction is needed in academic studies that address the quest for sustainability though BIM. Findings indicate future areas of BIM technology research include fully automating BIM-rating system integration, collaboration and intellectual property issues, and the unaccommodating contractual approaches for multiple party involvement needed in a BIM platform.
A BIM-Based Tool for Assessing Sustainability in Buildings Using the Green Pyramid Rating System
Buildings
Green construction management is an approach that aims to promote sustainable solutions in building design and construction. However, the complexity and variability in design scenarios often pose challenges to implementing these practices effectively. This study proposes a collaborative framework for green construction management that leverages automated and semi-automated simulations to facilitate performance-based decision making. The framework utilizes the green pyramid rating system (GPRS) as a third-party certification assessment provider. It employs various BIM analysis software tools, including Dynamo codes in Autodesk Revit and add-in plug-ins using Revit API, to extract information and parameters from the BIM model. The data are used to perform quantitative calculations and comprehensive analysis that aid decision makers in investigating, analyzing, improving, and assessing sustainability aspects throughout the project. The proposed framework enables a structured approach t...
