THE EMPIRE STATE BUILDING, NEW YORK'S SUSTAINABILITY ICON
The Empire State Building, the World’s Most Famous Building, is the international icon of the New York City Skyline. An urban campus within a single building, it is modernized and amenitized for the 21st century.
The Empire State Building is also the leading international model for energy efficiency retrofits in the existing built environment. We have already reduced GHG emissions by 40% over the past decade.
To achieve the deep energy retrofit we focused attention on the building’s envelope, mechanical systems, and lighting.
REFLECTIVE BARRIERS
Barriers added behind each steam radiator to allow heat to better make its way into the building
WINDOW INSTALLATION
Comprehensive reconstuction performed and installed to improve the building’s 6,514 windows’ resistance to heat and cold transfer
ENERGY EFFICIENCY
State-of-the-art lighting, insulation and elevator technology installed to improve energy efficiency inside the building.
Certified Since 2010 
LEED EB O&M v4 Gold

Set to be completed in 2023, the new community solar project at <a href=”https://build-esrt.pantheonsite.io/properties/office/500-mamaroneck-avenue1/”>500 Mamaroneck Avenue</a> will serve as a new sustainability initiative which attract and retain employees who value environmental leadership and action.
Local residents will share in the solar project’s benefits, which include electricity cost savings. The project will feature a new parking canopy solar array that will provide year-round elemental shelter for roughly 500 vehicles, an 8.2-MWh battery storage system, and approximately 80 electrical vehicle (EV) charging stations for tenant convenience.
The project is among the first installations in the state to incorporate the innovative mix of community solar, storage, and EV charging.
ESRT’s diverse portfolio benefits from both the Empire State Building and suburban buildings like 500 Mamaroneck Avenue, as this project is set to produce more than double the building’s annual energy usage. This undertaking is yet another way that ESRT innovates to achieve its sustainability goals, which include a target of net-zero carbon emissions for its entire portfolio by 2035.
SOLAR POWER
The solar array is expected to charge 50% of the building’s annual energy, which is equivalent to 3.1 million miles driven by an average car
ENERGY EFFICIENCY
Will produce enough power to fuel 2.5x the building’s annual energy usage
MAKING HISTORY
