ENERGY MANAGEMENT
IF-RE-130a.1 Energy consumption data coverage as a percentage
Total energy consumption data coverage from the Empire State Realty Trust operational portfolio, as a percentage of total/gross floor area, was equal to 100% in 2021 (excluding two multifamily assets acquired on 12/21/21) (1) ESRT’s total 2021 energy consumed by portfolio area with data coverage was equal to 353,165 gigajoules (GJ). (2) The percentage of total energy corresponding to grid electricity for all property types was 61%. (3) The percentage of total energy corresponding to onsite renewable energy for all property types was 0.0%, however, ESRT purchased 101,815,221 kwh (366,519 GJ) of Renewable Energy Credits from wind power to offset our electricity consumption. Total like-for-like change in energy consumption for the ESRT operational portfolio was 5% from 2020—2021. The COVID-19 pandemic caused a significant reduction of activity in our buildings during 2020 and 2021, resulting in reduced energy consumption, which is beginning to rebound as tenants return to offices. (1) 100% of ESRT’s operational office portfolio is benchmarked using ENERGY STAR Portfolio Manager. (2) 76% of ESRT’s office portfolio obtained ENERGY STAR Certification in 2021. ESRT utilizes Real Time Energy Management (RTEM) to integrate building energy management considerations into property investment analyses and their operational strategy. Real-time energy consumption feedback allows ESRT to realize cost and energy savings opportunities. ESRT has partnered with The New York State Energy Research and Development Authority (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 diagnostic. ESRT has also developed an Energy and Greenhouse Gas Management Policy that holds Portfolio Managers, Property Managers, Tenant Services Coordinators, and the Engineering Managers responsible for knowing their best practices and implementing the policy where possible for all assets under ESRT’s control. Portfolio managers are required to request updated Demand Response Plans from managers quarterly. The Energy Management Policy entails best practices such as tracking consumption through ENERGY STAR Portfolio Manager (ESPM), and conducting building energy audits that meet both the requirements of the ASHRAE preliminary energy use analysis and an ASHRAE Level 2 energy survey analysis identified in the ASHRAE Procedures for Commercial Building Energy Audits or equivalent. Additionally it is required that an ASHRAE Level 2 Audit is pursued in conjunction with local law compliance.
