Abstract

Abstract: This paper reviews Building Energy Modeling (BEM) development using classification and review of articles for the recent years (2015–2018) to explore how much BEM methodologies have been used Building Information Modeling (BIM) database during this period. Nowadays, BEM and supervision are the most important challenges of smart cities, and BIM has a good and useful source of information for buildings. Recent innovations have provided the opportunity for construction industry to invest in state-of-the-art technologies and adopt new processes. Among these new methodologies is BIM, which has developed for the construction industry over the last two decades. Integrating graphical and non-graphical information, it enables construction industry stakeholders to work collaboratively for efficient project delivery throughout the life cycle of construction projects. The use of BEM in construction industry has come about to respond to the global call for energy conservation and sustainability. BEM tools and processes can be used to simulate energy performance, evaluate energy needs and optimize architectural design. This article reviews and classifies BEM applications into eight different categories such as prediction, estimation, consumption, optimal design, evaluation, efficiency, management, and optimization. In addition to examination of BEM in different categories and according to BIM that is a coordination model and includes all information in construction industry as well as electrical, mechanical, and architectural information, this review paper wants to know how many articles have used BIM such as a database in this industry. Abstract : Highlights: Lots of work was done with EnergyPlus as EM software rather than other EM softwares. A few papers have used BIM as a database for accurate data entry that some of them have presented new methods for EM. In large-scale, for integration BIM and GIS, graphic interface is needed to allow non-IT professionals to easily conduct data queries. In large scale the quantity and quality of BIM remains a big challenge, because the LOD of the BIM software is much more than the GIS modeling scale, existing BIMs are often incomplete, and the data content often does not strictly follow the standard. The lack of interoperability between BIM and BEM causes difficulties in the development and delivery of projects that are seeking sustainable, efficient and good energy performance throughout its life cycle, for example incomplete or incorrect HVAC system modeling and missing information about controls. Information sharing between BIM authoring tools and BEM tools currently relies on open exchange formats of IFC and gbXML. Both provide means of storing geometry with attributed data; however, this information is often not accurately exported by the BIM tool or interpretable by the BEM tool. Use of BIM authoring tools to do so is costly for building operators who would need to purchase software and invest in training to extract relevant information. The main reasons for ignoring BIM as a database are: 1) low BIM training, and 2) very low willingness for owners to use BIM due to the exact calculation of construction costs. Owners think that the BIM will add to construction costs, while BIM will reduce the construction costs.
