In this comprehensive guide, we’ll delve into all aspects of LL87, including its requirements, benefits, and how Energy Efficiency Report can assist you in navigating through it.

What is New York Local Law 87?

Local Law 87, enacted in 2009, is a critical piece of legislation aimed at improving energy efficiency and reducing greenhouse gas emissions in New York City buildings. This law mandates that all buildings over 50,000 square feet undergo energy audit and retro-commissioning assessments every ten years. These assessments are designed to identify opportunities for energy efficiency improvements and ensure that buildings operate at peak performance.

Key Components of Local Law 87: Energy Audit and Retro-Commissioning

  1. Energy Audit: An energy audit is a comprehensive assessment of a building’s energy usage and systems. It involves analyzing energy bills, conducting on-site inspections, and identifying areas of inefficiency. The goal is to pinpoint opportunities for energy savings and prioritize cost-effective upgrades.
  2. Retro-Commissioning: Retro-commissioning focuses on optimizing the performance of a building’s existing systems, such as HVAC, lighting, and controls. It involves testing and adjusting equipment, updating operating procedures, and resolving deficiencies to improve energy efficiency and occupant comfort.

Who Needs to Comply with Local Law 87?

LL87 applies to all buildings in New York City that exceed 50,000 square feet in gross floor area, including commercial, residential, and mixed-use properties. Building owners are responsible for ensuring compliance with LL87 requirements and submitting the necessary documentation to the Department of Buildings (DOB).

Benefits of Compliance with Local Law 87

  1. Reduced Operating Costs: By identifying and implementing energy-saving measures, building owners can significantly reduce utility expenses and improve their bottom line.
  2. Improved Tenant Comfort: Energy-efficient buildings often provide better indoor air quality, temperature control, and lighting, leading to increased tenant satisfaction and retention.
  3. Environmental Impact: By reducing energy consumption and greenhouse gas emissions, LL87 plays a vital role in combating climate change and creating a more sustainable city.
  4. Legal Compliance: Failure to comply with LL87 can result in fines and penalties from the DOB, as well as reputational damage for building owners.
