Abstract
Repair and retrofit of social and affordable housing (also known as community housing) improves living conditions and reduces residential greenhouse gas (GHG) emissions. Many policies and programs target the condition and energy efficiency of these buildings, often characterized by deferred maintenance. These policies are critical for mitigating climate change and preserving affordable housing, especially for vulnerable people. However, their effectiveness is constrained by the complexity of urban social housing systems, given overlapping jurisdictions and the diversity of actors, policy domains, regional climates, and energy systems. Non-profit housing actors primarily make asset management and maintenance decisions to provide safe, affordable, and accessible housing – decisions that can lead to energy efficiency retrofits. However, retrofit decision-making is a dynamic process of negotiation between actors and materials evolving over several stages. To design integrated and transformative policies, understanding and comparing systems shaping these decision-making processes is essential. Using a systems approach and mixed methods we: 1) identify materials and broader system elements influencing early-stage decision-making from the perspectives of community housing actors; 2) map the strength of these influencing factors across four early stages of the retrofit decision-making process; and 3) compare how local contexts shape the influential factors in two contrasting systems, Saskatchewan (SK) and British Columbia (BC), Canada. We identify 16 influencing factors and map them across four project stages: identification, prioritization, design , and approvals . Building issues, funding availability, and impact on residents are key drivers, though factors vary across stages and depend on local contexts. We conclude with policy and program recommendations. • Non-profit actors navigate complex systems to maintain social and affordable housing • Retrofit decision-making is integrated with asset management practices • “Process systems map” identifies key project stages and influencing factors • Factors shaped by integration of local actors, asset management and energy policy • Comparing local systems identifies affordable housing retrofit pathways

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
