IF-RE-130a.5 Description of how building energy management considerations are integrated into property investment analysis and operational strategy
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 4 energy survey analysis identified in the ASHRAE Procedures for Commercial Building Energy Audits or equivalent.
WATER MANAGEMENT
IF-RE-140a.1
Water withdrawal data coverage as a percentage of (1) total floor area and (2) floor area in regions with High or Extremely High Baseline Water Stress, by property subsector
(1) Total water consumption data coverage from the ESRT operational portfolio, as a percentage of total/gross floor area, was equal to 100% in 2023. (2) 0%
(1) ESRT’s total 2023 water consumed by portfolio area with data coverage was equal to 492,992 m 3 (2) 0.0%
IF-RE-140a.2 (1) Total water withdrawn by portfolio area with data coverage and (2) percentage in regions with High or Extremely High Baseline Water Stress, by property subsector IF-RE-140a.3 Like-for-like percentage change in water withdrawn for portfolio area with data coverage, by property subsector IF-RE-140a.4 Description of water management risks and discussion of strategies and practices to mitigate those risks
Like-for-like change in water consumption for the ESRT operational portfolio was 0.36% increase in 2022-2023. The like-for- like change in commercial water consumption for ESRT was 0.47% increase in 2022-2023. Empire State Realty Trust strives to reduce water usage and promote conservation efforts by implementing water conservation initiatives including installing ultra-low flow plumbing fixtures and utilizing efficient cleaning and landscaping practices. This policy applies to all existing assets. ESRT’s water management policy is broken down by asset-level baseline and performance requirements. The baseline requirements entail the identification of current sources and end uses of potable water at the asset, obtaining billing information—such as account and water meter numbers, and metering locations—tracking water usage through ENERGY STAR Portfolio Manager (ESPM) profiles, and using a water intelligence tool, Wint, to identify potential leaks, monitor water use, analyze water use trends, and identify abnormal consumption trend in real time. 100% of our commercial and multifamily portfolio has implemented this smart technology. ESRTs performance requirements seek to maintain these baseline requirements and build upon them by setting and tracking performance goals, ensuring the ESPM profiles are being updated and water conservation best practices are in place, fixing identified leaks, installing high efficiency low-flow fixtures or retrofit low-flow aerators/fixtures where appropriate and feasible, and engaging with tenants.
