How this is computed| Period | Occupancy | GFA | Cap | Actual | Delta | Est. penalty | Status | Methodology |
|---|---|---|---|---|---|---|---|---|
| 2024-29 | B(high) | 1,828,353 sqft | 15,468 tCO2e | 16,184 tCO2e | +716.4 | $191,985 | Over cap | v1.0 |

Cap = Σ (occupancy_coefficient × gross_floor_area) using DOB LL97 rules; actual GHG is the most recent LL84 filing. Delta is positive when actual exceeds cap. Estimated penalty is DOB's public $268/tCO2e × delta with a 30-day grace applied via penalty_estimate_usd.
LL84 GHG emissions history
Actual tCO2e reported to LL84 by report year. Each bar links to the raw LL84 row identifier under the chart for auditability.

Records are the union of DOB Violations (3h2n-5cm9), ECB (6bgk-3dad), Safety Violations (855j-jady), OATH Hearings (jz4z-kudi), and OATH Trials (y3hw-z6bm) that we could link back to this BBL via BIN or address parsing. Events not tagged LL97-specific are shown as building-scoped context. See methodology · enforcement linking.
Fields we cannot show here (internal DOB data not yet public)
Processing lifecycleDOB's internal BEAM system tracks per-building compliance stages, RCE / decarbonization plans, and mitigation credits. Those fields are not yet published as an open dataset. When DOB releases them, this product will show them here without a schema migration. Until then, the following are known gaps for this building:
