The reduction of water consumption in buildings reduces overall environmental impact, drives operational cost savings, and reduces risk from fluctuations in water supply. 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 each of these through water processing, water fixtures, 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.

8 ESRT commercial office utilization increased approximately 30% over a five-day average (Monday–Friday) and three-day average (Tuesday–Thursday) in 2023 compared to 2022. This occupancy increase contributes to increased emissions, energy and water usage, and waste generation. The data above represents the utility usage of our office and multifamily portfolio. Data is absolute, and is not normalized for weather, occupancy, or other variables which impact usage and are not based on the impacts of efficiency efforts. Like-for-like metrics include properties owned for full calendar year 2022 and 2023.
