New Local Law 97 Space Emissions Allowances
Published on: July 1, 2024

Just when you thought you had Local Law 97 under wraps, the DOB "enhanced" the reporting requirements.

What was a simple analysis using Local Law 84 Data and your Building Gross Area - is now an indepth building science experience.


Under the new regulations, buildings must categorize their spaces into Energy Star “Property Types.” Each tenant space within a building needs to be measured and classified, such as a general office, financial office, medical office, gym, retail space, and so on.

Each property type is assigned its own designated greenhouse gas (GHG) limit, as detailed in the tables below. These property type-specific GHG limits are then combined in a weighted average to generate a custom GHG limit tailored to your building. This approach ensures that each building’s unique characteristics and usage patterns are accurately accounted for, promoting more effective and sustainable energy management strategies.

Summary of 1 RCNY §103-14 - Local Law 97

Purpose: This regulation mandates how building owners in New York City should report their greenhouse gas (GHG) emissions to help reduce the city’s overall emissions and combat climate change.

Key Terms

Beneficial Electrification: Using energy-efficient electric systems to replace fossil fuels.

Campus Energy Resource: Energy generated centrally and distributed to multiple buildings in a campus setting.

Emissions Factor: A value representing the building's emissions per square foot.

Energy Audit: A detailed examination of a building's energy use to improve efficiency.

Reporting Requirements

Timeline: Reports are due annually by May 1, starting in 2025.

Tool: Reports must be submitted using a specific tool provided by the Department.

Documentation: Owners must keep all records used in preparing the report for six years.

Special Cases

Condominium Buildings: Emissions must be reported as a single entity.

New Buildings: Reporting starts the year after they receive their Certificate of Occupancy.

Change in Ownership: New owners aren’t required to report for the year they acquire the building.

Emissions Factors

Different property types have specific emissions factors that determine their GHG limits. For example, a hospital has a higher emissions factor than a retail store due to its higher energy use.


Single Occupancy Group: Multiply the building’s square footage by its specific emissions factor.

Multiple Occupancy Groups: Sum the products of each group's square footage and its emissions factor.

Greenhouse Gas Coefficients

These coefficients are used to calculate emissions based on the type of fuel or energy source used.

Adjustments and Deductions

Adjustments: Owners can request adjustments to their emissions limits under certain conditions.

Deductions: Deductions can be made for renewable energy credits or energy storage systems.


The goal is to reduce GHG emissions from buildings, which are a significant source of the city’s total emissions. By adhering to these regulations, building owners contribute to a cleaner, more sustainable city.
