INTRODUCTION

ESRT purchases wind power to provide 100% renewable electricity to the portfolio.

ENERGY We focus our efforts on ROI-driven energy efficiency strategies, cutting-edge technology, and advanced analytics to achieve portfolio- wide quantifiable performance improvements. Our holistic energy efficiency approach is as follows:

MONITOR ENERGY CONSUMPTION We leverage advanced analytics and track energy data in ENERGY STAR Portfolio Manager to understand performance.

EVALUATE PERFORMANCE We perform energy audits and implement energy conservation measures. 100% of our properties have conducted energy audits in the last three years.

REDUCE PEAK DEMAND AND IMPROVE GRID RESILIENCE Demand Response programs reduce our energy consumption, costs, and emissions. 100% of our properties in the NY region participate in Demand Response and demand management programs.

TENANT ENGAGEMENT We partner with our tenants to educate them and drive ROI-based energy efficiency practices.

RENEWABLE ENERGY We offset our emissions through Green-e certified RECs. Since January 1, 2010, the Empire State Building has purchased over 41,000 Mwh of RECs to offset 100% of the electricity used in the building and nearly 17,000 MTCO 2 e. As of January 1, 2021, we offset 100% of the electricity used in our portfolio through clean renewable wind power RECs.

REAL TIME ENERGY MANAGEMENT (RTEM) Real-time energy consumption feedback allows us to realize cost and energy savings opportunities. We partner with NYSERDA to implement. RTEM incentives for control upgrades, chiller plant optimization, tenant energy management, tenant air handling units, lighting controls, plug load monitoring, and ongoing services that use predictive analysis and diagnostics.
