2018 Building Performance Analysis Conference and SimBuild – Co-organized by ASHRAE and IBPSA-USA
Chicago, IL | September 26–28, 2018


The 2018 Building Performance Analysis Conference and SimBuild, co-organized by ASHRAE and IBPSA-USA, will be held September 26–28, 2018 at the Hilton Chicago, Chicago, IL. It is the third co-organized conference between ASHRAE and IBPSA-USA.

The goal of this conference is to present the new techniques and workflows that will help researchers and practitioners make better decisions during the simulation and modeling process of an entire building life cycle.

The conference program will consist of Keynote Speakers, Invited Speakers, a Call for Papers, a Call for Presenters and the fourth ASHRAE LowDown Showdown. Special panels may be offered by industry leaders and organizations.

  • Call for Presentations

    Call For Presentations


    ASHRAE and IBPSA-USA announce a call for presentations for the 2018 Building Performance Analysis Conference and SimBuild, co-organized by ASHRAE and IBPSA-USA.

    Researchers, practitioners and building modeling professionals are invited to submit presentation/session proposals that  can be 15-90 minutes in length and can cover a broad range of topics addressing the needs of the building performance modeling community. Creativity in presentation format and audience engagement is strongly encouraged.

    Submitters will choose their presentation type from the following list:

    1. Team Case Studies: (15 min, 25 min, 45 min, 60 min or 90 min) Coordinated presentation from several members of high performance building design projects.  The abstract should include a detailed description of the project, design goals, modeling challenges, performance benchmarks used and experiences from all stages of design, construction and operation.  Also identify the team members and include brief descriptions of their role in the project and the presentation.
    2. Individual Presentations:  Traditional seminar type presentation on topics of interest to the conference attendees.  Presentation duration is 15 minutes.
    3. Pecha-Kucha: Visually compelling presentations with a maximum limit of 30 slides, each presented in 30 seconds each with a recommended limit of maximum 30 words per slide (unlimited images sans text).
    4. TEDergy Talk: Similar to the popular TED (Technology, Entertainment and Design) talk presentations, TEDergy talk is intended to address a specific novel idea, new modeling technique, workflow, software utility or technology in a concise 10 minute presentation to generate audience interest and participation.

    All submissions must include:

    • Presentation title
    • Duration of presentation
    • Speaker information
    • 100 word abstract.

    The conference seeks presentations on the following topics:

    • Building Information Model Technology Nexus
    • Modeling Advances (New techniques, scripting, etc.)
    • Early Design Modeling and Analysis
    • Multiple Systems Modeling
    • Health, Wellness and Comfort
    • Energy Performance and System Simulation (including existing buildings, model calibration)
    • Codes, Standards and Compliance Modeling
  • Call for Papers

    Call for Papers

    The Call for papers is now CLOSED

    ASHRAE and IBPSA-USA announced a call for papers for the 2018 Building Performance Analysis Conference and SimBuild, co-organized by ASHRAE and IBPSA-USA. It will be the third co-organized conference between the two organizations and will take place at the Hilton Chicago, September 26 – 28, 2018.

    “Building performance modeling is transforming the industry to meet the net zero and Architecture 2030 design goals, improving operational efficiency and occupant comfort,” said Krishnan Gowri, conference chair. “Recent advancements in machine learning, data science and sensor technologies are opening up new avenues to advance the analysis and modeling techniques to meet the challenges faced by designers and modelers.  This conference seeks to connect the researchers and industry practitioners to facilitate the adoption of these new techniques and workflows to make better decisions through the application of simulation and modeling over the entire building life cycle.”

    Modelers, architects, software developers and researchers will address the practices of building performance analysis, energy modeling and building performance simulation using existing simulation tools, software development and future simulation research and applications.

    The conference accepted abstracts on the following topics:

    • Buildings and Information Technology Nexus
    • Modeling Advances
    • Early Design
    • Multiple Systems Modeling
    • Big Data
    • Health, Wellness and Comfort
    • Energy Performance and System Simulation
    • Codes, Standards and Compliance

    Papers are due February 9, 2018 and will undergo a double-blind review. Conference papers should not exceed eight pages.

  • LowDown Showdown

    The 4th Annual ASHRAE LowDown Showdown will be held in conjunction with the 2018 Building Performance Analysis Conference and SimBuild co-organized by ASHRAE and IBPSA-USA.

    2017 LowDown Showdown Results >>

    How Creative Are You?

    Every year the LowDown Showdown has a new twist.  This year the competition calls on you to unleash your inner creativity (as well as your analytic skills) as you team up to model our most challenging building type to date.  

    The focus of the 2018 Building Performance Analysis Conference and SimBuild is the adoption of new techniques and workflows to advance modeling and simulation to meet the growing challenges faced by today’s designers and modelers.  In that spirit, the 2018 LowDown Showdown challenges teams to go beyond just achieving an energy efficient building, and use their ingenuity to include elements of conference themes into their design and analysis.  In fact, getting to “near net zero” will be a part of the model building baseline.  That in and of itself will be a challenge, as the model building for 2018 is a 60,000 sf museum (new construction) located in Denver, Colorado and to include retail space and a full service restaurant. 

    The goal of the 2018 LDSd competition is to engage participants in a collaborative and fun learning experience that explores new advances in building science, modeling and technology.

    Each team will create and submit a poster of their building design, a performance analysis model and results spreadsheet, and write a one-page narrative on project workflow.  Participants will also be required to submit graphics to Project StaSIO, an online crowd sourced repository of modeling graphics and images.

    Modeling and calculation workflow, building designs, systems and control strategies should be creative without being implausible from a cost standpoint.  To that end, one of the requirements will be a cost per square foot spending limit.  However, each team may include two (2) elements in its project that are not required to be included in the project costs.   Teams will be judged in two phases.  Phase 1 will be based on their initial entry.  Phase 2 judging will occur at the conference after teams have presented their projects. Teams will be judged on seven categories: Creativity, Innovative Approaches, Workflow, Energy Use, Calibration, Teamwork and Presentation. 

    So get your creative juices flowing, start rounding up your team members and check back for our next update in February to include more information on the judging criteria and prizing!!
