The LL97 Carbon Emissions Calculator estimates a building’s carbon penalty as a result of NYC LL97.
Automatically load building data from NYC’s benchmarking database or manually enter information to generate carbon thresholds, potential penalties, and utility cost metrics for three compliance periods.
Rich Energy provides multiple 100%, $0 upfront funding options to help you comply with LL97, reduce your energy usage, and save money.
The building emissions law sets emissions intensity limits (metric tons of CO2e per square foot) for 10 building categories based on Building Code occupancy groups. However, the answer for each building is complex.
Many, such as those with more than 35 percent rent-regulated units, are not subject to emissions limits (see more below). Mixed-use buildings, such as residential apartment buildings with a ground-floor supermarket or retail store, will have limits that reflect their unique blend of occupancy groups.
Below are the 2024 and 2030 carbon emissions limits for multifamily apartments, offices, and hotels. The law provides limits in metric tons of carbon dioxide equivalent; the following table and Metered.nyc express these numbers in kilograms of carbon dioxide equivalent (one metric ton equals 1000 kg). Limits for other building types are listed in the law.
To see a building’s annual emissions intensity based on the most recent benchmarking submissions, search by borough-block-lot (BBL) number or type in your street address at Metered.nyc. Scroll down to “GHG Emissions / sq.ft.” which is highlighted in green. Multiply that emissions intensity by a building’s total area (in square feet) to determine annual carbon emissions for the applicable year.
Calculating total building emissions depends on an “emissions factor” applied to each source of energy (e.g. natural gas, electricity or district steam) based on its associated carbon pollution. The benchmarking platform and Metered.nyc use emissions factors from the EPA’s Portfolio Manager tool.
