Purpose of Guides

This guide is one of a series developed with the goal of implementing consistent, simple, purpose-driven measurement processes to help quantify the impact of projects designed to further New York City’s greenhouse gas (GHG) reduction goals. These guides are designed for use by internal and external stakeholders to facilitate comprehensive characterizations of building energy consumption and promote standardized and reasonable reporting of avoided energy use, through the collection of energy-related system data in buildings owned or operated by the City. Stakeholders include personnel at the NYC Department of Citywide Administrative Services Division of Energy Management (DCAS DEM), NYCAgency Energy Personnel, and third-party consulting engineers and/or other measurement and verification (M&V) providers. These measurement guides may also provide direction to other
municipalities or private sector organizations that are looking to quantify avoided energy use for applicable energy conservation measures (ECMs).

General Overview of NYC GHG Reduction Goals

As the hub for energy management for the City’s fixed infrastructure, DEM plays a critical role in supporting NYC agency partners’ progress toward major emissions reduction and energy objectives. These goals include:

  • 80×50, focuses on achieving an 80% reduction in total economy-wide emissions in NYC by 2050 from a 2005 baseline. NYC also has an 80 x 50 goal relative to an FY06 baseline. OneNYC 2050 extended this goal by committing to net-zero greenhouse gas (GHG) emissions Citywide byThis will require 100% clean energy and offsetting sources of irreducible emissions.

  • 50×30, a new target created by the Climate Mobilization Act (NYC Local Law 97 of 2019) that focuses on achieving a 50% reduction in emissions by 2030, relative to an FY06 baseline. This includes all operations, facilities, and assets that are owned or leased by the City and for which the City pays all or part of the annual energy bills.

  • 40×25, a new interim target on path to 50×30 that was also included in the Climate Mobilization Act and applies to all City government operations.

  • Solar Target of 100MWx25, focuses on installing 100 Megawatts (MW) of solar photovoltaic (PV) at City government facilities by 2025.

  • Energy Storage Target of 100MWhx20, focuses on installing 100 Megawatt hours (MWh) of energy storage at both private and public facilities by 2020.
