Upload slides, poster, and pre-recorded video for your presentation in ConfTool system before August 31.

Presentation Modes

The author of the accepted research paper or project reports will be invited to present their work during BS2023. The designated types are ORAL and POSTER. If you attend the conference online, you can only choose oral presentation. All presenters need to finalize their slides, poster, videos and upload them to the ConfTool system before August 31. (a step-by-step guide)

Oral Presentation  

Each academic session lasts 120 minutes, dedicated to a specific topic in the realm of building simulation. It allocates 15 minutes for each oral presentation with slides, plus 2 minutes of Q&A organized flexibly by session chairs. There will be volunteers on site to help you with technical issues and cue you in about the remaining time.

You may follow your own style preparing the slides, by using the template down below as the front page. The slide size should be 16:9 for widescreen. Sans-serif fonts are recommended to increase readability. Please upload your slides beforehand to the ConfTool system.

  • Public computer with an internet connection (Windows 11)
  • MS PowerPoint by default. PDF and HTML accepted
  • Upload compressed file pack if local resources are linked in slides
  • Embed fonts in the .pptx file if unusual fonts are used
  • Laser pointer provided

Virtual attendees will join the online ZOOM conference room for virtual sessions. Same as the physical one, the virtual session allows 15 minutes pre-recorded video for each presenter with 2 minutes of Q&A. To ensure a smooth program, please upload the video to the ConfTool system in advance. The ZOOM link will be available in the ConfTool conference agenda, and on the website.

Note that the virtual sessions are hosted each conference day during 7:00-9:00 and 20:00-22:00, open for all participants. Except for the plenary session (live-streaming), the sessions onsite are segregated from the virtual ones. Virtual attendees cannot join the discussion onsite, only can access the recordings published on the website.

Poster Presentation  

Poster sessions are organized concurrently with coffee breaks. The attendees may visit the poster gallery and engage with the presenters while enjoying the refreshments. Choosing the poster presentation, you need to make an A0-size poster in color. A0 size equals 841 x 1189 mm or 33.1 x 46.8''. Follow the templates (in MS PowerPoint, Adobe Illustrator, or Photoshop) down below and lead your own creative design.

The poster will be displayed both onsite and online. You are allowed to upload a 5-minute video as a brief introduction or supplement material (demo/promo). We will paste a QR code to the poster redirecting visitors to the online resources, so they may "engage" with you in your absence. If you have more to share via this QR code, contact secretariat@bs2023.org

The poster (in JPG/PDF or source file) and the video need to be uploaded in the ConfTool system as the second and third final uploads. Other recommendations:

  • A0 size, > 150 DPI, color printing on coated paper
  • Free content design with header and footer in line with templates
  • Two-column or four-column layout system is recommended
  • Using Sans-serif fonts (Montserrat/Open-Sans for example)
  • Booth decoration allowed (sticky notes, tear-off flyer, etc.)

Bring your poster with you, or have it printed locally. Recognizing the inconveniences associated with transporting large posters, we offer services for having your poster printed at local companies. Put up your poster on the registration day (Sept. 3rd). The poster wall is in a zigzag layout as depicted in the following mock-up.

Local Poster Printing  

We provide the poster printing service cooperated with local companies. The A0 poster will be printed in color, with 300 DPI, on self-adhesive paper coated by matte film. The service charges 7 USD (50 CNY) per each. There might be minor flaws at bleeds when the printer cuts the paper down. We are not responsible for any color discrepancy caused by RGB to CMYK conversion. The local printing service is now closed.

  • Deliver your poster file to us via ConfTool "Final Upload"
  • Transfer $7 to PayPal getech1018@hotmail.com or ¥50 via Alipay , with the Contribution ID as a payment note.
  • You receive an email once we confirm your payment and start processing the request.
  • Fetch your poster at conference check-in on September 3rd.

Contribution Types

As a platform promoting communications from both academy and industry world, BS2023 calls for research papers, project reports and workshop proposals, to best represent the latest breakthroughs in the realm of building simulation.
If you would like to purpose an event such as invited speech or panel discussion, please contact info@bs2023.org.

Research paper

The research paper is 8 pages long, aiming for the latest breakthroughs in the application of building simulations. All papers accepted and presented will be published in the Conference Proceedings, indexed by EI, and open-accessed on the IBPSA website.

Project report

The 4-page-long project report is case-focused, best demonstrating an effective application of the building simulation. This type of contribution only requires an extended abstract and will not be published in the conference proceedings. We are expecting 1~2 sessions for this kind of contribution.


Workshops target the promotion and education of simulation techniques, such as software demos, vendor-sponsored training, panel discussion, or student projects. Submissions will be evaluated on a first-come-first-served basis, provided that there is a clear link with building simulation. All workshops are self-financed.


BS2023 continues to use ConfTool for abstract submission. All authors with an accepted abstract are invited to upload their manuscript (paper, project report and workshop proposal) in the ConfTool system before April 3. Please refer to the templates above. Each contribution will be evaluated through a double-blind peer review, scored and subsequently accepted for presentation. The scientific committee reserves the right to classify your work in terms of relevant track, contribution or presentation type.

Check out the following bullets before you continue:

  • Please make a new full-text submission in the ConfTool system
  • Please use the templates provided when preparing your manuscripts.
  • The manuscript of the research paper should be within 8 pages, while the project report within 4.
  • A PDF version of your manuscript must be uploaded. (<10MB)
  • An editable version of your manuscript must be uploaded. It depends on which template you are using (Word/LaTeX). The LaTeX files must be compilable and packed in a ZIP file. (<10MB)
  • Please do not include names, affiliations and acknowledgments in your draft for review.
  • The updated submission deadline is April 3, 2023. (Midnight CST)

If you encounter any technical issues, please refer to this user guide or contact us.
