The Carl T. Hayden Veterans Affairs (VA) Medical Center in Phoenix, Arizona, demonstrates that grid-interactive efficient building (GEB) strategies and technologies can be realistically deployed across buildings with substantial energy and cost savings.
The project implemented both energy conservation measures (ECMs) and grid-interactive technologies and controls strategies, making it a leading example of a smart, sustainable, and efficient commercial building.
Ultimately, these ECM retrofits helped the medical center achieve over 25% energy savings and an ENERGY STAR® rating of 99, making it one of the most energy-efficient medical centers in the United States.
This case study highlights the challenges and the lessons learned throughout the project development and implementation, in addition to some of the best practices for project management, operations, load shifting and peak management, and heating, ventilation, and air-conditioning (HVAC) system management.
