Penalty Estimates: LL97 penalty estimates are calculated based on the most recent year of LL84 benchmarking energy data, provided the information meets minimum screening criteria for data quality. If this data is not available, the tool uses the most recent data that meets these criteria.
Disclaimer: NYC Accelerator's Building Energy Snapshot displays estimated penalty amounts, compliance pathways, and energy savings that will vary annually. Projections are intended to aid LL97 planning but may not exactly match actual penalties and savings. The compliance pathways are based on DOB's LL97 Covered Buildings List (CBL), which were compiled using preliminary data that is subject to change. This information is intended only as a reference for building owners to consider in consultation with legal representatives and registered design professionals (RDPs). The presence or absence of any property on the CBL does not relieve it from compliance with LL97 or any other applicable law.
