Manhattan Building Energy Benchmarking

NYC Local Law 84 compliance data for Manhattan, New York City

Energy Benchmarking in Manhattan

Manhattan concentrates the largest share of New York City's energy-intensive commercial buildings, including office towers, hotels, and mixed-use high-rises. Properties across Midtown, the Financial District, and the Upper West Side account for a substantial portion of citywide greenhouse gas emissions. Many Manhattan buildings carry significant Local Law 97 exposure, making real-time benchmarking intelligence essential for consultants and property managers.

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 Manhattan

NYC Local Law 97 (LL97) sets greenhouse gas emissions caps for most buildings over 25,000 square feet. Properties in Manhattan 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 Manhattan 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.
