How this is computed

Period	Occupancy	GFA	Cap	Actual	Delta	Est. penalty	Status	Methodology
2024-29	B(medium)	1,028,016 sqft	8,697 tCO2e	34,247 tCO2e	+25,550	$6,847,348	Over cap	v1.0
2030-34	B(medium)	1,028,016 sqft	4,656.9 tCO2e	34,247 tCO2e	+29,590	$7,930,095	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 lifecycle

DOB'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:

Assessed penalty (vs theoretical)
Actual penalty DOB assessed against a building, distinct from the theoretical over-cap exposure computed from LL84 emissions.
Simulated · internal DOB data not yet public
Best-effort shadow field: ecb_summons_issued
Public release status: announced_not_yet_released
Audit assignment
Buildings selected by DOB for LL97 filing audit and the audit stage.
