ECOBEE METADATA PROCESSING NOTES
================================

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
