Local Law 97 (LL97) is a groundbreaking piece of legislation aimed at reducing greenhouse gas emissions in New York City. Enacted as part of the Climate Mobilization Act, it targets buildings over 25,000 square feet, requiring them to meet stringent carbon emission limits. As the city pushes towards a greener future, property owners and managers must navigate the complexities of compliance. One critical step in this process is conducting comprehensive energy audits. The Cotocon Group, a leader in sustainability consulting services, offers expert guidance to help buildings meet LL97 requirements efficiently and effectively.

Understanding Local Law 97

What is Local Law 97?

Local Law 97 is one of the most ambitious climate laws passed by any city in the world. It sets limits on greenhouse gas emissions for large buildings, with strict penalties for non-compliance. Starting in 2024, buildings must adhere to specific emission thresholds, which will become progressively stricter in subsequent years. The ultimate goal is to reduce the city’s overall emissions by 40% by 2030 and 80% by 2050.

Why is LL97 Important?

NYC Local Law 97 is critical for several reasons. First, buildings are responsible for nearly 70% of New York City’s greenhouse gas emissions. By targeting this sector, the law aims to make a significant impact on the city’s carbon footprint. Second, it positions New York City as a leader in climate action, setting an example for other urban centers globally. Finally, compliance with LL97 can result in substantial cost savings for building owners through reduced energy consumption and improved operational efficiency.

The Importance of Energy Audits

What is an Energy Audit?

An energy audit is a thorough examination of a building’s energy use. It identifies where energy is being consumed, where waste is occurring, and opportunities for efficiency improvements. Energy audits typically involve a detailed analysis of building systems, including heating, ventilation, air conditioning (HVAC), lighting, insulation, and other infrastructure.

Types of Energy Audits

There are generally three levels of energy audits:

  1. Level 1: Walk-Through Assessment – This is a basic overview of a building’s energy consumption and highlights major areas for improvement.
  2. Level 2: Energy Survey and Analysis – This involves a more detailed examination, including a breakdown of energy use by system and recommendations for efficiency measures.
  3. Level 3: Detailed Analysis of Capital-Intensive Modifications – This comprehensive audit involves an in-depth analysis of energy systems and often includes modeling and simulation to predict energy savings from various measures.

How Energy Audits Aid in LL97 Compliance

Conducting an energy audit is a crucial first step in complying with NYC Local Law 97. Here’s how energy audits facilitate compliance:

  1. Baseline Establishment: Energy audits help establish a baseline of current energy consumption and emissions. This is essential for understanding how a building measures up against LL97 targets.
  2. Identifying Inefficiencies: Audits pinpoint inefficiencies and areas where energy consumption can be reduced. This includes identifying outdated or malfunctioning equipment, poor insulation, and suboptimal lighting.
  3. Actionable Recommendations: Based on the findings, audits provide actionable recommendations for energy-saving measures. These can range from simple behavioral changes to major capital improvements.
  4. Cost-Benefit Analysis: Energy audits often include a cost-benefit analysis of recommended measures, helping building owners prioritize investments that offer the greatest return in terms of energy savings and emission reductions.
  5. Compliance Roadmap: The audit results in a clear roadmap for achieving compliance with LL97, detailing the steps needed to reduce emissions within the required timeframe.
