Local Law 97 (LL97): The Time To Act Is Now

As the calendar turns to 2024, New York City’s Local Law 97 (LL97) has officially entered full swing, ushering in a new era of carbon emission reduction and energy efficiency for buildings over 25,000 square feet. For property managers and resident managers, the time to make changes and ensure compliance with LL97 is now. Failure to meet the requirements of this ambitious law can result in significant penalties and fines, potentially exceeding a million dollars, depending on your building’s size. 

In this article, we will explore the key aspects of LL97, its requirements, penalties for noncompliance, and how innovative solutions like CitiQuiet’s interior window systems can help property owners meet these standards affordably and effectively.

Understanding Local Law 97

Local Law 97, enacted in April 2019, is a groundbreaking initiative aimed at reducing greenhouse gas (GHG) emissions from buildings in New York City. It targets structures over 25,000 square feet, encompassing approximately 50,000 residential and commercial buildings across the city. The law sets strict limits on carbon emissions, with the enforcement of these limits beginning in January 2024.

To comply with LL97, building owners are required to reduce their annual carbon emissions to meet the newly proposed standards. While various methods can be employed to achieve compliance, the focus is on reducing energy consumption and emissions. For property managers and resident managers, understanding the implications of this law is crucial to avoid penalties and contribute to a greener New York City.

Penalties for Noncompliance

Local Law 97 imposes penalties for noncompliance to encourage building owners to take carbon emission reduction seriously. The penalties include:

  1. Carbon Emission Fines: Buildings emitting more carbon dioxide (CO2) than allowed by their emission cap will face fines. The fines are calculated at a rate of up to $268 per ton of CO2 exceeding the cap. These fines can quickly add up, making compliance essential.
  2. Failure to Report: Failure to submit the required yearly carbon emissions report will also result in penalties. Buildings will be fined at a rate of $0.50 per square foot per month for each month that the emissions are not reported. For larger buildings, this penalty can escalate rapidly, potentially reaching over a million dollars annually.

Enforcement of LL97

Enforcing Local Law 97 falls under the purview of the Department of Buildings (DOB) in New York City. The DOB has been responsible for disseminating information and overseeing the transition to LL97. However, a new office, the Office of Building Energy and Emissions Performance (BEEP), has been established within the DOB. BEEP will serve as the primary point of contact for compliance, penalties, and oversight once fully operational.

Meeting LL97 Compliance: Your Options

Meeting Local Law 97 compliance depends on several factors, including the age and condition of your building. Older structures may require more extensive and costly renovations, such as facade reconstruction, to improve energy efficiency and reduce emissions. In contrast, newer buildings may have more straightforward compliance options.

For property owners and managers seeking cost-effective and minimally intrusive solutions to meet LL97 requirements, CitiQuiet offers innovative interior window systems. These interior window inserts do not require the removal of existing windows, simplifying the retrofitting process.
