Environmental Health 63 2021 Sustainability Report A Modern, High-Performing Health System Introduction Our People and Culture Responsible Business Practices Performance Data Improving energy efficiency in our buildings Supporting the transition to renewable energy A significant part of our commitment to operational net-zero includes identifying and scaling our reliance on renewable energy sources, which will directly decrease greenhouse gas emissions and improve the health of the communities where we operate. We are currently evaluating the sourcing of renewable energy across our operations, including on-site and off-site renewable energy production, virtual power purchase agreements and other renewable purchasing options. Examples of renewable energy sourcing could include deploying on-site solar systems on parking garages and rooftops at targeted core facilities, investing in off-site renewable solar and wind development, and other renewable purchasing options available through our utility partners. Our approach provides an opportunity to shift the broader demand for renewable energy in the communities where we operate. To meet our operational net-zero commitment, we are scaling solutions that reduce energy consumption in our entire real estate footprint — ranging from data centers and pharmaceutical distribution centers, to clinical care facilities. This approach includes new construction projects, renovations, collaboration with landlords and simple employee behavior programs. For example, we are finalizing the construction of phase 1 of a two-building, 352,000-square-foot administrative campus in San Antonio, Texas. Phase 1 is scheduled to open in 2022. It represents what will be the first WELL-certified campus in our portfolio, an industry-recognized attestation measuring a facility’s health and human experience attributes through building design and operations. We plan to leverage this experience to inform future construction. Additionally, we continue to invest in energy efficiency projects, including LED fixture upgrades, HVAC system replacements and Building Management Systems installation.
