APSC 261 sustainability project : an investigation into the use of cob and/or straw bale construction in non-residential buildings
Bibliographic record
Abstract
The report investigates the use of cob and/or straw bale construction in non-residential buildings. The main purpose of the investigation is to present the possibility of having a building or a section of a building be constructed at the UBC Farm. The new structure will act as a farm centre managed by the Centre for Sustainable Food Systems. At the farm centre, students, professors and the general public will have the opportunity to learn about sustainable technologies. The investigation begins by identifying what cob and straw bale is and how it is used in the construction of buildings. Additionally, the similarities and differences of cob and straw bale construction are explored. Furthermore, three case studies of non-residential cob buildings are described and summarized. Next, a triple bottom line assessment was used to evaluate the possibility of using cob and/or straw bale construction at the UBC Farm. This assessment consists of three indicators: social, environmental and economic. The social factors include accessibility to local construction resources, safety and comfort of the building as well as the impact of such a building on the local community. The environmental issues involved exploring the carbon footprint of using cob and straw bale as well as how the material will fare in Vancouver’s climate. Lastly, the economic factors include assessing the production, labour and maintenance costs as well as the lifetime of a cob and straw bale building. Finally, after using the triple bottom line assessment to evaluate the possibility of using cob and/or straw bale construction for a new farm centre, the results recommend a section of the new farm centre be constructed using cob and straw bale.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
