Local Law 87 (LL87) is a pivotal piece of legislation in New York City aimed at enhancing energy efficiency and reducing carbon emissions in buildings. For building owners, understanding LL87 is crucial not only for compliance but also for optimizing energy usage and minimizing operational costs. In this guide, we'll delve into the intricacies of LL87, its requirements, deadlines, compliance process, and provide valuable insights to facilitate a smooth journey through energy audits and retro-commissioning.

Understanding Local Law 87

LL87 was enacted in 2009 as part of the city's broader efforts to combat climate change and promote sustainability. Its primary focus is on large buildings, which are significant contributors to energy consumption and greenhouse gas emissions. The law mandates energy audits and retro-commissioning assessments at regular intervals to identify energy-saving opportunities and ensure buildings operate at peak efficiency.

Requirements and Deadlines

One of the key aspects of LL87 is its periodic cycle for compliance. Buildings covered under LL87 must comply with the following timeline:

·      Energy Efficiency Report (EER) Submission: Building owners are required to submit an EER to the New York City Department of Buildings (DOB) every ten years. The EER outlines the building's energy usage, identifies potential areas for improvement, and includes recommendations for energy conservation measures.

·         Energy Audit: Within the first four years of each compliance period, buildings must undergo an energy audit conducted by a qualified energy auditor. The audit assesses the building's energy performance, identifies inefficiencies, and proposes measures to enhance energy efficiency.

·         Retro-Commissioning: Following the energy audit, buildings are required to undergo retro-commissioning within two years. Retro-commissioning involves optimizing the performance of existing building systems, such as HVAC, lighting, and controls, to ensure they operate efficiently and effectively.

Compliance Process

Navigating the compliance process can seem daunting, but with proper planning and assistance, building owners can streamline the process. Here's a breakdown of the steps involved:

Hiring Qualified Professionals:

Engage qualified energy auditors and retro-commissioning agents who are accredited by the DOB and familiar with LL87 requirements. These professionals will guide you through the process, conduct assessments, and prepare necessary documentation.

Conducting Energy Audit:

The energy audit is a comprehensive assessment of your building's energy usage, systems, and operational practices. The auditor will analyze utility bills, conduct on-site inspections, and identify areas for improvement.

Implementing Energy Conservation Measures:

Based on the findings of the energy audit, prioritize and implement energy conservation measures (ECMs) that offer the highest return on investment. These may include upgrading lighting systems, improving insulation, optimizing HVAC controls, or installing energy-efficient equipment.

Completing Retro-Commissioning:

Retro-commissioning aims to optimize the performance of building systems through adjustments, repairs, or upgrades. Work closely with retro-commissioning agents to implement recommended measures and ensure compliance with LL87 standards.

Tips for Success

Successfully navigating LL87 requires proactive planning and collaboration. Here are some tips to help building owners achieve compliance effectively:

1.    Start Early: Begin the compliance process well in advance of the deadline to allow ample time for assessments, implementation, and any necessary adjustments.

2.   Maintain Documentation: Keep detailed records of energy audits, retro-commissioning reports, and ECM implementations for submission to the DOB. Accurate documentation is essential for demonstrating compliance.

3. Seek Incentives and Rebates: Take advantage of available incentives, rebates, and financing options offered by utilities, government agencies, and other organizations to offset the cost of energy efficiency upgrades.

4. Embrace Technology: Explore innovative technologies such as smart building systems, energy management software, and IoT devices to monitor and optimize energy usage in real-time.

Conclusion

Local Law 87 presents both challenges and opportunities for building owners in New York City. By understanding the requirements, deadlines, and compliance process, as well as implementing proactive energy-saving measures, building owners can not only meet regulatory obligations but also enhance the sustainability and performance of their properties. Embracing energy efficiency is not only a legal requirement but also a strategic investment in the future of our buildings and our planet.
