Student Modeling Competition

It is a considerable amount of time that is needed to tackle every challenge, which is why we encourage particular universities and lecturers to make the brief part of their modules. Since the students have to do the assignment anyway participating in a course, they can use that to submit documentation to the modeling competition.
Should this not be the case, this needs to be done in your private and leisure time, which is still possible, because a lot of information was provided to you such as the climate constraints and conditions around. (Please refer to webinar recording on Youtube or ZOOM). This is very valuable information that will save you already a considerable amount of time when you start working on that document.
To emphasize, this is a group challenge, so we invite groups of people to participate. You can find teams inter-disciplinarily within different universities and countries. We encourage such submission as a team, where shared work always decreases the workload.
We also limit application documents to 20 pages in order not to encourage people to write a lot because this is not a writing assignment. The limitations that the students are aware of what they did and the assumptions that they made would be very important to us when judging those submissions.

We only look at the reports, not the models. Should there be any queries, however, we will take the liberty to approach the group in hindsight and request the models. But the challenge is for the students to put all the necessary information in the document they submit. Should there be any additional information, such as tables of values, etc., is allowed to use an appendix added at the very end. Please don't rely on this because, in the first step, we will just look at the 20 pages, so try to put the core information in that.

You may download the slides here.

There are some materials recommended in the briefing document, only for reference. Students may consider replacing such materials to meet the requirements mentioned in the briefing document.

We won't be able to share the list of the participants. We encourage people to step forward as teams already. It is not how it works, to look for members in the participant list. You have to find team members prior and submit as a group. The deadline (February 15th) is for you to show your intent to contribute to the competition (not the deadline for your report). That is important for us to get an overall idea of how many people will participate.
We can't publish the list. What we will publish in the end, however, are the two finalist teams that will present their work at BS2023. Other than that, we will keep the information confidential of those who have applied.

To avoid bias in translation, we have put the requirements of the local code in the briefing document. Those not listed are for your own decision. For example, for the ventilation rate you mentioned, we have put the ACH (air change per hour) in the document for your reference.
The energy code in China is quite different from other countries, so we only provide some basic requirements in the document. We have added some references in the website in the document named “information expansion about energy codes in China”. If there are any further demand about the code or other issues, please feel free to post them on the MIRO board. We will work with you and give you feedback on that platform.
This is one of the challenges of every competition because we encourage you to familiarize yourself with different climate conditions, building regulations, constraints about materials, and everything, which is why we pose the building usually in the hosting country. Information about this will be published on the website. Please look at this before you start modeling.

We usually expect the teams to let us know all the participants' names because what we require from all of you is a certificate that you are still enrolled at a university, whether that is a Bachelor, MSc, or Ph.D. This is indented for students, not for practitioners.
If there is a situation where you find out that you have submitted just a team of three, and you would like to add the fourth member on hindsight who has been very influential to this, surely we can talk about this. It is always good for you to collaborate with more people than fewer.
But again, we will require proof of enrollment at a university for every team member.

We will not provide a base case for this year's competition. You may refer to the requirements of the local design codes and standards, which are quite applicable to the current climate and building function, with recommendations about the optimization. Please refer to the document named “information expansion about energy codes in China” which can be downloaded from our website.
We had base cases in the past where we sort of provided more data and information on base or equivalent cases or even monitor data and then asked students to change the building based on the baseline. It is not the challenge this year. If you are uncertain about the performance of the building, look at equivalent data, and try to find references to that, but do not worry about a base case for analysis in this case.

The competition challenge is quite comprehensive, encompassing architecture, mechanical systems, etc., so it is up to the participants to choose the most suitable way for their teamwork and integration.
For this year’s competition, MIRO is used to encourage students to exchange ideas and collaborate. This is one example of a workspace where people can create a profile, work together, ask and answer questions.

From the perspective of IBPSA, if you use the case you must cite IBPSA and the modeling brief within your thesis, applications, or any publications because this brief is developed as part of the conference with IBPSA on the conference host. So, you will have to reference that document.
In addition, from the perspective of architectural designers, if you use the case within your thesis, applications, or any publications, you must include the following acknowledgments and cite at least one of the following references.

Thanks to ATELIER L+, Tongji Architectural Design (Group) Co. for providing design materials for this study.

The RH level of occupied hours is not mandatory for your simulation. However, you should inform yourself what is necessary for the type of simulation that you have to conduct, and dry bulb temperature is, most of the time, not sufficient on its own.

Surely you can incorporate BIM in your simulation workflow. However, the building model will not be delivered by the host in any form of BIM.

Your choice of the thermal performance of the building envelope should meet the constraints in the first table of Appendix B. The recommended materials provided in the second table of Appendix B are just for your consideration. You can choose other materials instead.
Those recommended materials are extracted from the Public Building (DGJ 08-107-2015), as shown in Appendix B Physical thermal data of building materials, and Appendix C Thermal transmittance of energy windows of Design Standard for energy efficiency. Those are common building materials in China and are listed here as examples. You can get more information by browsing this standard.

There are no specific calculation requirements for the stairs and staircases. The modeling should reflect their characteristics of heat transfer or energy consumption.

Only the energy consumption and carbon emissions of the tower part are studied, with the podium part excluded. The circulation area of the podium and tower may serve as passive ventilation paths. Therefore, the podium spaces adjacent to the tower part should be treated as non-conditioned.

We are sorry for the typo in Appendix B. The conductivity constraints (W/m·K) should be the thermal transmittance coefficient constrains (W/m²·K). Relative documents have been updated. Corrigendum.pdf

They are matched. The floor labeling starts from 1 in China (1, 2, 3...) while by European tradition it starts from 0 (ground floor, 1st floor, 2st floor, ..., top floor).
