2021 ASHRAE Building Performance Analysis Conference

November 10-12, 2021 | The Curtis Hotel, Denver, CO

NEW! Hybrid Format




ASHRAE will host its first hybrid conference for the annual Building Performance Analysis Conference November 10-12 in Denver, CO. Practitioners, vendors, researchers, utility and government officials, and owners will address the practices of energy modeling and building performance simulation using existing simulation tools, software development, and future simulation research and applications.

The anticipated conference program consists of Keynote Speakers, Invited Speakers, a Call for Presentations and the seventh ASHRAE LowDown Showdown. Special panels may be offered by industry leaders and organizations.

Conference attendees will have the option to gather in-person under CDC, hotel and ASHRAE Covid-19 safety restrictions and guidelines, or attend the conference live via a virtual platform. The virtual format will include a mixture of live and on-demand technical and interactive sessions.  

“ The past year has brought forward new challenges for the design and operation of new and existing buildings, in particular challenges related to the health and well being of occupants,” says John Bynum, conference chair. “Additionally, interest in embodied energy and operational emissions continues to grow across the industry due to regulatory and other drivers. This conference will provide an opportunity for building professionals across disciplines to share and learn about these topics and many others as we continue to work towards a better built environment. 

Thank you to our Sponsors

  • Technical Program

    The theme for the conference is “Design and Operation for Resilient and Healthy Buildings”.

    Building performance analysis professionals and practitioners were invited to submit proposals for individual presentations, panels or seminars that cover a broad range of topics addressing the needs of the building performance analysis community.

  • LowDown Showdown

    The goal of the LowDown Showdown modeling competition is to engage participants in a collaborative and fun learning experience that explores new advances in building science, modeling and technology. Teams are comprised of building analysts, designers, architects, engineers and other participants. Teams will be responsible for creating the architectural design and a performance analysis model based on model building data. The teams may use any software or a combination of software to complete their projects.

    Each team will create and submit a poster of their building design, complete the performance analysis model and results spreadsheet and write a one-page narrative on project workflow. Teams will present their projects at the BPAC conference and be judged by a panel of industry experts who will select the winners. Teams will be judged on eight categories: Creativity, Innovative Approaches, Sustainability/Durability, Energy Use, Indoor Environmental Quality, Workflow, Teamwork and Presentation.

  • Pre-Conference Panels

    Pre-Conference Panels

    Two live virtual panels have been scheduled for Tuesday, November 9th, starting at 10:30 am (MT). Attendees must be registered for the conference to attend.

    Date: Tuesday, November 9
    Time: 10:30 AM - 12:00 PM

    Energy modeling, increasingly used for code and beyond-code compliance using rulesets like ASHRAE Standard 90.1 Performance Rating Method (Appendix-G), is complex, error-prone and currently requires manual verification. This seminar discusses ASHRAE Standard 229P, which will establish a BEM tool and ruleset independent framework to automatically verify the implementation of modeling rulesets. The Standard will facilitate the automation of submittal reviews and improve the consistency of compliance outcomes thereby reducing the burden on rating authorities and jurisdictions that adopt performance-based codes. Initially, Standard 229P will focus on Appendix-G, but can be easily adapted for other rulesets (ie: RESNET-HERS, CA-ACM).

    Data exchange mechanisms, such as gbXML, BDE, RMR, and BuildingSync define data schemas for representing building data for specific purposes. The schemas allow data to be easily exchanged between users and software. The schemas facilitate the use of multiple analytical tools and minimize manual effort involved in mapping and transforming data across multiple tools and workflows. This panel introduces these schemas, discuss use-cases, and highlight efforts to improve data exchange. A moderated discussion addresses the merits and challenges associated with data exchange mechanisms and how these can streamline the workflow of design, analysis, code compliance, and energy audits.

  • Unmet Hours LIVE!

    This year’s Building Performance Analysis Conference includes a unique conference event format -- Unmet Hours LIVE! In this session, each participant is first given time to think of a challenge they are facing. Then, participants are divided into groups and each person takes turns to present their problem and have it brainstormed by the group. This allows participants to seek out as well as provide peer-supported advice on solving each other's challenges. This is the same intent as -- the question-answer forum for building energy simulations -- but offered in a live, interactive, and dynamic format for conference attendees.

    Whether you're planning on attending the 2021 BPAC in-person or virtually, I would greatly appreciate it if people would fill out a survey to provide feedback on two things:

    1. Topics of interest
    2. If attendees plan on participating in-person or via webinar

    In the conference program, this event is Seminar 6 taking place from 10:30 AM - 12 PM on Thursday, November 11.
