WATER PERFORMANCE The reduction of water consumption in buildings minimizes overall environmental impact, drives operational cost savings, and reduces risk from fluctuations in water supply and combined sewer overflow, a significant challenge in NYC and cities around the world. Water usage reduction and water runoff quality and quantity management are critical issues for NYC and for ESRT, as a recipient of the municipal water supply. We address these issues through water processing, water fixtures, water submetering and associated software, green roofs, and native xeriscape planting. In 2023, we received the DOE’s Better Building Challenge Water Goal Achiever status with 97% passing data checks and 27% water use intensity improvement.

7 Occupancy increased by 16.6% at the Empire State Building and by 12.9% across the commercial portfolio in 2024 compared to 2023. This increase in occupancy contributes to increased water usage. The data above represents the water usage of ESRT’s commercial and multifamily portfolio that was owned for the full calendar year 2024. Data is absolute and is not normalized for weather, occupancy, tenant typology, or other variables that impact utility usage apart from efficiency initiatives. Like-for-like metrics represent ESRT’s NYC commercial office properties owned for the full calendar years of 2021 to 2024.
