EUI distribution across buildings
Each building's annualized EUI (published classes only — buildings in a below-minimum class are withheld); the spread shows efficiency variation.
By customer class
| Class | Buildings | p25 | Median site EUI | p75 | Source EUI | vs nat'l avg |
|---|---|---|---|---|---|---|
| RESIDENTIAL | 1202 | 24.9 | 40.1 | 65.7 | 112.3 | 134% |

Classes with fewer than 15 buildings are withheld (k-anonymity; Sweeney 2002, ESSnet SDC Handbook).

“vs nat'l avg” is coarse all-fuel sector context (CBECS 2018 / RECS 2020),
not the official ENERGY STAR 1–100 score (which needs property-type operational data + EPA's model).
