To address these challenges, Local Law 87 NYC was enacted to promote energy efficiency and sustainability in large buildings. This law requires property owners to conduct periodic energy audits and retro-commissioning to ensure optimal building performance. Energy audits are more than just a compliance requirement; they are a critical step toward identifying inefficiencies, improving energy management, and contributing to a greener future. Understanding the importance of energy audits under Local Law 87 helps property owners make informed decisions that benefit both their operations and the environment.

Understanding Local Law 87 NYC

Local Law 87 is part of the Greener, Greater Buildings Plan introduced by New York City to enhance energy performance in large buildings. The law applies to properties over 50,000 square feet and mandates that owners perform an energy audit and retro-commissioning every ten years.

Purpose of the Law

The main purpose of Local Law 87 NYC is to ensure that building owners are aware of their energy consumption and take necessary steps to improve efficiency. It encourages data-driven decision-making, promotes sustainability, and reduces greenhouse gas emissions.

Who Needs to Comply

The law applies to commercial, residential, and mixed-use buildings exceeding the size threshold. Building owners must file an Energy Efficiency Report (EER) with the Department of Buildings once every decade, which includes both the audit and retro-commissioning results.

Compliance Schedule

Each building’s compliance year corresponds to the last digit of its tax block number. Owners are required to complete the energy audit and retro-commissioning and submit the EER by December 31 of their assigned year. Failure to comply can result in substantial penalties and non-compliance status, which may affect building operations and financial standing.

What an Energy Audit Entails

An energy audit is a comprehensive evaluation of how a building uses energy. It involves analyzing systems, identifying inefficiencies, and recommending actionable improvements.

Types of Energy Audits

There are three standard levels of energy audits as defined by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). For Local Law 87 compliance, an ASHRAE Level II audit is typically required. This level provides a detailed analysis of energy use and identifies cost-effective measures for improving efficiency.

Key Areas Covered in the Audit

The audit examines all major energy-consuming systems within the building, including:

• Heating, ventilation, and air conditioning (HVAC) systems
• Lighting systems and controls
• Building envelope (insulation, windows, and air sealing)
• Domestic hot water systems
• Elevators and mechanical equipment

Through a detailed analysis of energy bills, on-site inspections, and system testing, auditors identify wasteful patterns and recommend strategies to enhance performance.

Benefits of Conducting an Energy Audit

Conducting an energy audit under Local Law 87 NYC provides multiple advantages:

• Energy Savings: Identifies cost-effective measures to lower consumption and utility costs.
• Operational Efficiency: Enhances the performance of building systems and reduces maintenance issues.
• Environmental Impact: Helps reduce carbon emissions and supports the city’s sustainability goals.
• Informed Decision-Making: Provides data-driven insights to guide future energy investments.

Retro-Commissioning: Ensuring Building Systems Work Efficiently

In addition to the audit, Local Law 87 requires retro-commissioning, which ensures that existing building systems are functioning as intended.

Purpose of Retro-Commissioning

Retro-commissioning focuses on fine-tuning building operations rather than replacing equipment. It ensures that all systems are properly calibrated, schedules align with occupancy, and unnecessary energy use is minimized.

Common Retro-Commissioning Measures

Retro-commissioning typically includes:

• Testing and adjusting HVAC controls
• Verifying sensor and thermostat accuracy
• Calibrating equipment for proper operation
• Ensuring that lighting controls function correctly
• Identifying and repairing leaks in air and water systems

These low-cost improvements can lead to significant energy savings and improved occupant comfort.

Verification and Reporting

Once retro-commissioning is completed, findings are documented in the Energy Efficiency Report. The report must be certified by a registered professional and submitted to the Department of Buildings to demonstrate compliance with Local Law 87 NYC.

The Importance of Energy Audits in New York City

Energy audits play a central role in the city’s efforts to build a more energy-efficient and sustainable future.

Supporting New York City’s Climate Goals

New York City has committed to ambitious climate targets, including reducing greenhouse gas emissions by 80 percent by 2050. Since buildings account for a large portion of these emissions, the implementation of Local Law 87 NYC is crucial in achieving these objectives.

Enhancing Building Performance

Energy audits help property owners understand how well their buildings are performing. They highlight inefficiencies and operational issues that, once addressed, lead to improved comfort levels, better air quality, and optimized energy usage.

Financial Benefits

While compliance may require an initial investment, the long-term savings from reduced utility costs can be substantial. In many cases, simple upgrades such as replacing outdated lighting or adjusting HVAC controls can lead to noticeable reductions in energy expenses.
