4 E SRT 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. Portfolio goals use a 2009 baseline year unless otherwise stated. Empire State Building initial calibrated energy model is based on full year 2007 data.
