In the evolving landscape of building performance regulations, nyc local law 87 plays a critical role in improving energy efficiency across large properties in New York City. This regulation requires periodic energy audits and retro commissioning measures to ensure that buildings operate efficiently and reduce overall energy consumption. Property owners, facility managers, and real estate stakeholders must understand compliance timelines, reporting standards, and technical expectations to avoid penalties and enhance long term building performance.

Overview of NYC Local Law 87
New York City introduced Local Law 87 as part of its broader sustainability initiative under the Greener, Greater Buildings Plan. The regulation applies to covered buildings that are larger than 50000 gross square feet, including single buildings and groups of buildings on the same tax lot that together exceed this threshold.
The primary objective of this law is to identify opportunities for energy savings through comprehensive energy audits and retro commissioning studies. By mandating performance evaluations every ten years, the city ensures that large buildings remain aligned with modern energy efficiency standards and operational best practices.
Buildings Covered Under the Law
Local Law 87 applies to most commercial and residential buildings exceeding the size requirement, including office towers, multifamily properties, mixed use developments, and institutional facilities. Certain exceptions exist, such as properties that have achieved specific high performance certifications within defined time frames.
Compliance is determined by the building block number, which dictates the year in which the Energy Efficiency Report must be submitted. Owners must verify their filing year carefully, as missing the assigned deadline can result in financial penalties and enforcement actions from the city.
Energy Audit Requirements
An energy audit involves a comprehensive assessment of a building’s energy systems and consumption patterns. This includes evaluating heating, ventilation, air conditioning systems, lighting systems, building envelope performance, and domestic hot water equipment.
The audit identifies energy conservation measures that are cost effective and practical for implementation. These recommendations often include equipment upgrades, control system improvements, lighting retrofits, and operational adjustments that collectively reduce energy usage and operating costs.
Retro Commissioning Process
Retro commissioning focuses on ensuring that existing building systems are functioning as intended. Over time, mechanical systems may drift from optimal performance due to wear, improper settings, or outdated control strategies. This process helps restore efficiency without necessarily replacing major equipment.
The retro commissioning scope includes testing, adjusting, and calibrating systems such as HVAC controls, sensors, dampers, and boilers. It also involves correcting deficiencies identified during inspection to ensure improved system performance and energy savings.
Energy Efficiency Report Filing
Once the audit and retro commissioning processes are completed, a comprehensive Energy Efficiency Report must be prepared and submitted to the New York City Department of Buildings. This report documents findings, outlines recommended measures, and confirms that retro commissioning requirements have been addressed.
The report must be certified by a qualified professional, such as a licensed engineer or registered architect. Proper documentation and accurate data entry are essential to avoid rejection, penalties, or the need for costly resubmissions.
Benefits of Compliance and Long Term Impact
Compliance offers more than regulatory alignment. Building owners gain valuable insight into system performance, uncover hidden inefficiencies, and identify practical improvements that reduce utility expenses. In many cases, recommended upgrades deliver measurable financial returns over time.
Beyond cost savings, the law contributes to broader environmental goals by lowering greenhouse gas emissions citywide. Improved energy performance enhances property value, strengthens tenant satisfaction, and positions buildings to meet additional requirements such as emissions limits under evolving climate regulations.
Conclusion
Understanding and complying with nyc local law 87 is essential for owners of large buildings in New York City. The regulation requires structured energy audits, retro commissioning measures, and proper reporting to ensure that properties operate efficiently and sustainably. By taking a proactive approach, stakeholders can reduce operational costs, improve system reliability, and avoid penalties associated with non compliance.
