Building Information Modeling

Journal

This article discusses the benefits of fully integrating Building Information Modeling (BIM) and intelligent document technology into the design and construction process. BIM technology is evolving at a rapid rate, and recent developments in computer hardware and software have brought significant new tools and resources to the architectural and engineering community.

Building Information Modeling: Gaining Momentum

Journal

Building information modeling (BIM) is gaining considerable momentum as the technology evolves and greater interoperability occurs between disparate software systems. The rapidly emerging goals of green building/sustainable design, towards net zero-energy buildings, coupled with goals for carbon dioxide emissions reduction, requires whole building, fully integrated design and construction as a dynamic process. This article shows how BIM can provide that integration.

Integrating Occupant Behavior Data into Building Information Modeling for Performance Simulation

Report

The ASHRAE RP-1815 project centers on advancing the state of occupant behavior modeling as part of building information modeling (BIM) and energy modeling and simulation (BEM) workflows. Enhancements to the industry data standards ifc and gbXML for BIM and BEM to support occupant behavior modeling data were a specific area of focus and project deliverable. The research draws heavily on Lawrence Berkeley’s obXML occupant behavior modeling schema as an influence and point of departure for this work. As part of this research, 16 stakeholder interviews were conducted to assess the state of the art and needs for improvements. A dozen existing research programs, software products and relevant data standards were evaluated to determine requirements for OBM supported BIM and BEM workflows and data standardization support. The report provides a comprehensive survey and review of existing technologies and standards' support of occupant behavior modeling. It emphasizes the crucial role of OBM in enhancing energy modeling accuracy and building performance analysis, identifying the need for more effective integration to capture the impact of occupant behavior on building energy use. Revisions to the gbXML schema have been developed and are now incorporated in the current gbXML consensus standard specification. IFC targeted enhancements have led to the development of a private online data dictionary hosted on building smart’s BSDD service. This work specifically anticipates use of gbXML and IFC in energy modeling workflows using the DOE’s EnergyPlus energy modeler including the system’s Functional Mockup (FMU) co-simulation capabilities, and the Open Studio application and APIs for model import, editing and export. Beyond these requirements, the research identified key enhancements in two other data formats: the obXML schema itself, where XML compliancy and other enhancements are proposed based on learning from the gbXML – obXML integration effort, and the DOE’s new epJSON input format as an alternative to today’s IDF for EnergyPlus model import. Numerous appendices, supplementary files, and online resources are provided as deliverables to the project.

Emerging Technologies: BIM for Energy Savings

Journal

Building information modeling (BIM) offers a wide range of information about a building. Its analysis tools could be used to meet energy standards and certifications and, by using third-party software that evaluates a building's overall energy performance, could help with energy savings. There is also an array of BIM analysis tools available to assist in evaluating building performance, some of which are geared towards energy analysis.

Defining the Capabilities, Needs and Current Limitations of Building Information Modeling (BIM) in Operations and Maintenance for HVAC&R

Report

The primary objective of this project was to formally specify information exchange use cases based on existing ASHRAE publications, documented according to the format of ASHRAE Guideline 20: Documenting HVAC&R Work Processes and Data Exchange Requirements (ASHRAE, 2010). It is hoped that the resulting information exchange documents and other project deliverables will be used within ASHRAE to serve as practical examples of how BIM technologies can support and improve practical work processes that are performed by ASHRAE members on a daily basis. It is critical that ASHRAE members contribute their domain expertise to guide the appropriate application of BIM technologies in their professional world.
