The Bronx Building Energy Benchmarking

NYC Local Law 84 compliance data for The Bronx, New York City

Energy Benchmarking in The Bronx

The Bronx is home to a substantial stock of large multi-family residential buildings, many of which have historically reported below-average ENERGY STAR scores relative to other NYC boroughs. Improving energy performance in Bronx buildings is a key priority in New York City's climate action plan. Building owners and property managers in The Bronx face the same LL84 annual filing requirements and LL97 emissions limits as properties across all five boroughs.

Data Source

Statistics are derived from NYC Local Law 84 Energy and Water Data Disclosure filings, covering buildings 25,000 sq ft or larger that are required to file annually through ENERGY STAR Portfolio Manager.

Local Law 97 in The Bronx

NYC Local Law 97 (LL97) sets greenhouse gas emissions caps for most buildings over 25,000 square feet. Properties in The Bronx that exceed their annual limit face fines of $268 per metric ton of CO₂e above the cap, calculated annually.

Phase 1 (2024–2029): Current compliance period with occupancy-specific emissions limits based on DOB building classification and GFA.
Phase 2 (2030+): Significantly stricter limits designed to drive deep decarbonization of NYC’s building stock.
Fines are computed per metric ton of CO₂e exceeding the building’s specific cap — making total GHG emissions the most critical compliance metric.

EnergiDash helps The Bronx building owners, property managers, and energy consultants understand their exact LL97 exposure in advance, using live ENERGY STAR Portfolio Manager data.

About NYC Local Law 84

Local Law 84 (LL84) requires most NYC buildings 25,000 sq ft or larger to benchmark their annual energy and water use through ENERGY STAR Portfolio Manager and report to the city by May 1 each year. The data is publicly disclosed through the NYC Energy and Water Data Disclosure program.

Buildings that fail to submit face escalating fines from the NYC Department of Finance.
The disclosed data — ENERGY STAR scores, EUI, and GHG emissions — forms the basis for LL97 fine calculations.
EnergiDash automates the pre-filing review process, flagging errors and data gaps before submissions are due.
