Over cap

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.
    Simulated · internal DOB data not yet public
    Public release status: announced_not_yet_released
  • Audit outcome
    Result of an LL97 audit (accepted / correction ordered / penalty referred).
    Simulated · internal DOB data not yet public
    Public release status: announced_not_yet_released
  • Extension flag
    Whether a per-building filing was accepted under a filing extension (June 30 grace or BEAM extension to August 29).
    Simulated · internal DOB data not yet public
    Public release status: announced_not_yet_released
  • Filing received date
    Timestamp DOB received a per-building LL97 compliance filing.

  • Good-faith effort application
    Whether an owner has applied for a good-faith effort determination and its status.

  • Mediated resolution application
    Application for the LL97 mediated resolution process and its outcome.

  • Notice of deficiency status
    Whether a notice of deficiency has been issued for a building and its current stage.

  • Per-building filing status
    Filing status for each covered BBL/BIN combination (filed / late / non-filed / exempt) as tracked in DOB's BEAM system.

  • RDP attestation
    Registered Design Professional attestation attached to each per-building compliance filing.

  • RECs / offsets claimed
    Renewable Energy Credits and beneficial-use offsets claimed to reduce reported emissions.

    The 60-day cure window state for a building under LL97 enforcement (open / cured / expired).

Every number on this page traces back to a Socrata dataset row or a CBL PDF revision. Where DOB does not publish a computable field (pathway, internal BEAM stage, compliance decision), we say so on the record instead of hiding the gap. See methodology.
