We completed a groundbreaking deep energy retrofit project at the Empire State Building, which serves as the leading global model demonstrating the business case for deep energy retrofits. All project information is publicly available and open source at www.esbsustainability.com

We developed practices for high performing tenant installations, and our Chairman and Chief Executive Officer led the program which made that information available as the Tenant Energy Optimization Program at the Urban Land Institute for which project information is publicly available and open source at https://tenantenergy.uli.org.

We implement this work throughout our entire portfolio. Our team of experts conducts on-going monitoring, verification and Tenant Energy Management (TEM) analytics. Based upon the latest methodology, which is far more stringent based on updates to Energy Star benchmarking data and methodology as of August 2019, 76% of our eligible office portfolio measured by square feet is Energy Star Certified. Energy Star-certified buildings meet strict energy performance standards set by the Environmental Protection Agency. They use less energy, are less expensive to operate, and have a reduced impact on the environment.
