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...
Building Information Modeling (BIM) for green buildings: A critical review and future directions
Although a large number of studies on Building Information Modeling (BIM) have been conducted in the past decade, a lack of consensus remains among researchers and practitioners regarding the applications of BIM for the development of green buildings, the activity of making buildings in a way that protects the natural environment. As the usefulness of BIM has been widely recognized in the building and construction industry, there is an urgent need to establish an up-to-date synthesis on the nexus between BIM and green buildings. After an indepth review of hundreds of journal articles published from 1999 to 2016 and 12 widely used types of BIM software, this study provides a holistic understanding and critical reflection on the nexus between BIM and green buildings, which is systematically illustrated by a "Green BIM Triangle" taxonomy. The proposed taxonomy indicates that the nexus between BIM and green buildings needs to be understood based on three dimensions, namely project phases, green attributes and BIM attributes. Following the proposed taxonomy, this paper systematically illustrated 1) the applications of BIM in supporting the design, construction, operation, and retrofitting processes of green buildings; 2) the various functions of BIM for green building analyses such as energy, emissions, and ventilation analysis; 3) the applications of BIM in supporting green building assessments (GBA); and 4) research gaps and future research directions in this area. Through critical review and synthesis of BIM and green buildings based on evidence from both academic research and industrial practices, this paper provides important guidance for building researchers and practitioners to better align BIM development with green building development in the future.
Enhancing environmental sustainability over building life cycles through green BIM: A review
Automation in Construction, 2015
The innovation of building information modelling (BIM) technology provides a new means of predicting, managing and monitoring the environmental impacts of project construction and development through virtual prototyping/visualisation technology. This paper aims to provide thought-provoking insights into the shortcomings in the scope of the existing green BIM literature, and outlines the most important directions for future research. A total of 84 green-BIM-related papers have been reviewed and compared. Most green BIM research, centres on environmental performance at the design (44 papers) and construction stages (25 papers) of building lifecycles. Few studies concentrated on the development of BIM-based tools for managing environmental performance during the building maintenance, retrofitting (8 papers), and demolition (12 papers) stages. It is suggested that a 'one-stop-shop' BIM for environmental sustainability monitoring and management over a building's full life cycle should be considered in future research. Future green BIM tools should also include the three R's concept (reduce, reuse and recycle) in their sustainability analysis for both new development and retrofitting projects. The system should offer better integration with facility operation maintenance manuals for more effective low-carbon management. The use of cloud-based BIM technology to enable the management of building sustainability using 'big data' is also needed. Despite these potential developments, it is argued that the lack of computer tools and the complications of the BIM models are hindering the adoption of green BIM.
Disaster and Risk Research: GADRI Book Series, 2021
Building information modeling (BIM) is a set of tools that represent the physical and functional properties of a building digitally. BIM is used to document building designs or simulate construction and operation of new facilities. The emerging model is information-rich and object-based, where data can be inserted, extracted, updated, modified, and analyzed to improve the design of facility. Owners initiate and finance building projects. By selecting service providers and deciding on the type of delivery process to be used, owners make very strategic decisions in the facility delivery process. The effectiveness of BIM on an integrated project depends on these conclusions and decisions. Nowadays, construction projects are also moving towards sustainability through owners being committed to having green-rated buildings and infrastructure. This paper focuses on building information modeling with an owner’s perspective since owners being committed to having green-rated buildings and how...
BIM-based Approach for Green Buildings in Malaysia
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...
Building information modelling and green buildings: challenges and opportunities
Architectural Engineering and Design Management, 2018
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.

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.
