Reducing the Energy Consumption of New Construction Residential Buildings in Ontario: The Development of Prescriptive Compliance Packages 20% Below Ontario Building Code Requirements
Bibliographic record
Abstract
To address energy concerns in new home construction in Ontario, advanced compliance packages have been developed that meet an energy reduction of 20% compared to SB-12 standards. The prescriptions are based on measures identified by homebuilders in the Savings by Design program. Energy simulations using HOT2000 have been conducted to establish the optimum combination of measures that will enable builders to meet the target, for 3 different house archetypes. Additional analysis was conducted to determine the effect of building orientation; climate; thermal bridging; air conditioning; and the SHGC of windows. A total of 9 advanced packages were developed. The findings from this study indicate that builders are more comfortable upgrading the systems components of a house as opposed to the building envelope components; different archetypes can reach the reduction target using different measures; and the other design factors must be considered in order to ensure the reduction target is achieved.

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.
