Throughout the past decade, New York City has implemented some of the strictest energy policies and targets throughout the country. Most notably, as an overarching goal, NYC has vowed to decrease their greenhouse gas emissions by 80% by the year 2050 (termed “80 x 50”). To help realize these goals, there have been a number of energy conservation codes published, such as the Climate Mobilization Act, that will impose harsh fines on business for noncompliance.

Below is a summary of some of these policies, as well as a brief overview of how ECS can assist with them. 


  • The Climate Mobilization Act of 2019 consists of four new Local Laws: 92, 94, 96, 97

  • While these laws are all vital in helping NYC reach its ambitions emissions goals in the near term, ECS can assist with the following: 

  • The centerpiece of the Climate Mobilization Act, Local Law 97 requires all buildings larger than 25,000 square feet to meet ambitious carbon reduction targets [1]

  • "Under this legislation, large buildings will be subject to major financial penalties if carbon intensity targets are not met starting in 2024, with more aggressive targets starting in 2029. While most buildings will not be exposed to potential penalties until 2029, owners and operators need to move quickly to mitigate potential exposure to LL97’s penalties. Commercial buildings face additional challenges, not least of which being that energy consumption by tenants is often outside the direct control of building management. This post hopes to bring to light some of the more nuanced considerations for commercial buildings to help navigate early preparation for your property.” [2]

    • ​  Goal of 80% reductions by 2050 (termed “80 x 50”)

    • Allowed intensities will be put in place in 5-year increments (2024-2029, 2030-2035, etc.)

    • Civic penalties begin in 2024 if above threshold

    • Penalties up to $268/MtCO2e above the limit. For example, a 250,000 SF commercial office building will have a proposed limit of 2,115 tons of CO2 beginning in 2024. If this building were to reach just half of the 40% savings goal and exceed the limit by 20%, the projected fine would be $113,364.00 per year. 

    • Annual reports will be required 5/1/2025 and every year thereafter


Bottom Line: LED Lighting upgrades have been known to decrease a building’s overall energy usage by up to 30%. Contact us today to schedule your assessment and start understanding how ECS can help you get to the LL97 finish line.

Local Law 97

  • Local Law 88 of 2009 and its subsequent expansions with Local Laws 132 and 134 of 2016, require common areas in residential buildings greater than 25,000 square feet and all areas in non-residential buildings greater than 25,000 square feet to upgrade lighting to meet current New York City Energy Conservation Code standards by January 1, 2025

  • LL 88 also requires that all non-residential buildings greater than 25,000 square feet install electrical sub-meters for each large non-residential tenant space greater than 5,000 square feet and to provide monthly statements summarizing energy consumption in those spaces.

Bottom Line: Allow ECS to perform an investment grade audit of your facility’s lighting systems and determine the most economical and efficient path forward to LL88 compliance

Local Law 88

Local Law 95

  • Require all buildings in NYC over 25,000sf to publicly post their letter grade annually beginning in October 2020. Letter grades will be based on the previous calendar year's Energy Star Scores.

  • Local Law 95 amends Local Law 33 by refining the letter grades associated with different ranges of Energy Star scores. 

  • These grades are based on an Energy Efficiency score, which is assigned through the benchmarking process as well as Water Usage.

  • An Energy Star score of 85 or above will be considered an "A"
    70-84 is a "B"
    55-69 is a "C"
    54 and below is a "D"
    Noncompliance leads to an "F"
    Exempted buildings and properties for which Energy Star cannot calculate a score will receive an "N"

  •  LL96 implements long-term, low interest Property-Assessed Clean Energy (PACE) financing to fund upgrades to building energy and water efficiency. 

  • ECS can help to secure this financing and get your property on its way to meeting these energy efficiency requirements. 

Local Law 96

  •  Local laws 92 and 94 require all new buildings and buildings undergoing major roof renovations to be covered with solar panels, green roofs, or some combination of the two. The laws also require all buildings to reduce urban heat hazards.
