What is the
Sweet 16 is a single-stage international wall assembly competition held annually by @bs_and_beer_kc. Participants are tasked with designing a wall assembly for their given climate zone while considering six criteria with a focus on applied building science.
The inaugural 2020 competition, created as a way to combat boredom during the global lockdown and share building science pitted 16 submissions against each other from across the United States. The second annual Sweet 16 places emphasis on the work of skilled-trade, architectural, and design students from across North America.
Wall assemblies are a pivotal aspect of envelope design in residential construction and the foundation of many students' initial application of building science. While the focus of the competition remains wall assemblies, critical attention must be paid to the connections and proposed assemblies of adjoining foundations, floors and roofs.
The competition is open to any student in North America.
There is no fee to enter.
We put your wall assembly in a cage
match with the best of the best.
Submissions can be made by any current student as an individual, group, or class submission.
The entries must be submitted electronically as two separate PDF files not exceeding 10MB each. Each entry should contain, in order, the following documents (in English):
Document One: 8.5" x 11" - Project Summary
- 1-2 page(s) maximum (see template example)
- A maximum of 150-word text describing the project
- A maximum of 100-word text describing each response
to the six criteria
Document Two: 8.5" x 11" - Images and Drawings
- 5 pages maximum, with one image/drawing* per page
- Up to 4 views or images of your wall assembly (section, axonometric, perspective, photos of the mockup, etc.)
- A perspective of the wall assembly in its entirety (from the footing to the roof)
* Note: preference for portrait images so that they can be shared as Instagram Posts and for voting purposes by @bs_and_beer_kc
An evaluation of the control layers to assess thermal performance & potential air-tightness
Ease of workability or installation on the jobsite and availability of material spec’d
The longevity of the assembly given water shedding and vapor control, with a focus on reparability
Based on an 8’ wide by 10’ tall mock wall assembly and totaling the embodied carbon of the complete assembly
Including labor and material (with the inclusion of special equip. like cranes for pre-built assemblies)
Does the assembly allow for future
remodeling, and when the assembly is finally deconstructed what is the level of reuse, recyclability & toxicity of materials
Note: Criteria will be analyzed according to the submission’s local climate zone and material/labour economy
