REFIT METADATA PROCESSING REPORT

Output file: refit_processed_metadata.csv
Rows preserved: 20
Columns preserved from metadata_cols_to_keep.yaml: 45

1. Scope
- Kept only the columns defined in metadata_cols_to_keep.yaml.
- Preserved the same row count and building IDs as the input REFIT metadata file.
- Standardized values to align with the classes used in results-Baseline.csv when a clear mapping was possible.
- Left values null when confidence was low or no clean reference-class mapping was available.

2. Column-level changes made

3. Assumptions used
- Building type mapping: Detached was mapped to Single-Family Detached.
- Building type mapping: Semi-detached and Mid-terrace were mapped to Single-Family Attached.
- Versions of vintage labels that did not match the reference classes were binned into the nearest baseline class using the date range implied by the text.
- Vintage examples used: 1975-1980 -> 1970s and 1960-79; 1981-1990 -> 1980s and 1980-99; pre-1940 labels -> <1940.
- All homes were treated as located in or around Loughborough when filling location-based fields because the source metadata used Loughborough as the weather city.
- weather_file_latitude was filled as 52.7667 and weather_file_longitude as -1.2 as approximate coordinates for Loughborough.
- county_metro_status was filled as Metropolitan as a best-fit standardization rather than a direct UK administrative equivalent.
- ashrae_iecc_climate_zone_2004 and ashrae_iecc_climate_zone_2004_2_a_split were filled as 4C as a best-fit climate analogue for Loughborough.
- building_america_climate_zone was filled as Marine as a best-fit climate analogue for Loughborough.
- weather_file_city was left null because Loughborough did not clearly match one of the baseline city classes.
- geometry_garage was left null when the source value could not be confidently translated into a baseline class such as 1 Car, 2 Car, or 3 Car.
- neighbors values from REFIT were not forced into the output when they did not cleanly match the baseline classes; low-confidence cases were left null.
- Any field not directly inferable from the REFIT metadata or not confidently mappable to a baseline class was left null.

4. Confidence notes
- High confidence: row count preservation, column filtering, direct building-type remaps, and straightforward vintage binning.
- Medium confidence: latitude/longitude for Loughborough.
- Low confidence: climate-zone analogues and metro-status analogue, because the baseline taxonomy appears US-centric while REFIT is UK-based.
- Low confidence: any inferred geographic/categorical field without an exact REFIT source value or exact baseline class equivalent.
