| ================================ |
|
|
| Column-by-Column Changes and Assumptions: |
|
|
| 1. building_type |
| - ‘single_family_detached’ → ‘Single-Family Detached’ |
| 2. construction_type |
| - ‘wood_frame’ → ‘Wood Frame’ |
| 3. exterior_finish |
| - ‘wood’ → ‘Wood, Medium/Dark’ |
| 4. hvac_system |
| - ‘heat_pump’ → ‘Non-Ducted Heat Pump’ |
| 5. heating_fuel |
| - ‘heat_pump_electric’ → ‘Electricity MSHP’ |
| 6. window_type |
| - ‘triple_pane’ → ‘Triple, Low-E, Non-metal, Air, L-Gain’ |
| 7. vintage |
| - ‘2018’ → ‘2010s’ |
| 8. floor_area |
| - Input: 155 (assumed square meters) |
| - Converted ≈ 1668 sq ft |
| - Mapped to category: ‘1500-1999’ |
| - Bin assigned: ‘1500-2499’ |
| 9. climate_zone |
| - Not provided → inferred as ‘5A’ |
| - Climate classification: ‘Cold’ |
| - Assumption based on likely U.S. mid-latitude residential context |
| 10. latitude / longitude |
| - Not explicitly provided |
| - Not inferred due to insufficient location info → left null |
| 11. PUMA |
| - Not available → left null |
| 12. metro_status |
| - Not available → left null |
| 13. insulation details |
| - Not provided → left null |
| 14. garage |
| - Not provided → left null |
| 15. orientation |
| - Not provided → left null |
| 16. weather_city |
| - Not provided → left null |
|
|
| Confidence Notes: |
|
|
| - High confidence: direct categorical mappings (building type, HVAC, |
| windows) |
| - Medium confidence: floor area conversion and binning |
| - Low confidence: climate zone inference |
| - Very low confidence: geographic and contextual fields → left null |
