The United States Army is increasingly shifting the focus of energy and water investments to reduce risk to mission accomplishment and strengthen energy and water security. Finding ways to do this while also reducing demand and lowering costs is the ideal outcome. The U.S. Army Medical Command (MEDCOM) has designed, built and commissioned the first Department of Defense (DoD) Leadership in Energy and Environmental Design (LEED) Platinum hospital at the National Training Center at Fort Irwin, California. Weed Army Community Hospital (WACH) reached LEED Platinum through onsite renewable energy, passive sustainable design, and high-efficiency systems. The new hospital allows soldiers and their family members to receive the best medical care while encouraging excellence in sustainable medical facility practices. WACH breaks barriers in both renewable energy production and energy conservation. It has been dubbed “the greenest hospital in the world” by those associated with the project. All of this is a significant accomplishment in and of itself, but what really resonates with the Army is mission assurance – the length of time the hospital can function if energy and water supplies are disrupted. This session will examine the unique techniques employed through MEDCOM’s Health Facility Planning Agency to combine resiliency, security and sustainability in this newest hospital. This session will review the design concepts and features incorporated into the hospital and resulting benefits to the Army.
