Water Efficiency We implement water efficiency strategies to support our water reduction goals and minimize our impact on the environment. Our Water Management Policy and water efficiency strategies include: • Set a baseline and track performance against goals • Update water data quarterly in ENERGY STAR Portfolio Manager • Research, pilot, and implement water management technologies and strategies in base building and tenant spaces • Continue to install new or retrofit existing fixtures for ultra-low- flow models and track progress • Continue submetering and real-time monitoring, machine learning, and management software across the commercial and multifamily portfolio • Maintain annual water quality testing and compliance with WELLv2 and LEEDv5 • Proactively prevent, identify, and rectify leaks • Track impact of HVAC energy efficiency on water reduction • Track all renovations to ensure consistent implementation of standards and update goals accordingly Low-Flow Retrofits and Upgrades As part of our sustainability standards, we continue to implement ultra-low-flow fixtures and appliances that are EPA WaterSense labeled. Each year, our building management teams conduct a comprehensive survey of each water fixture to record flow rates and ensure compliance with our standards. This assessment aims to identify areas for improvement and help us achieve our consumption reduction goal of 30% from 2018 baseline year by 2030.

Advanced AI Software-Based Water Submeters To monitor and measure water consumption by end-use and identify areas for targeted reduction, we installed submeters for all central water systems across our portfolio. We use machine learning software to detect and notify property management of unnecessary water usage and potential leaks, monitor water use contemporaneously, and analyze trends. This technology enables our property managers and engineers to knowledgeably manage consumption and make informed operational decisions in real time.
