Weed Army Community Hospital

On-Site Energy Management

SEA led the way in helping WEED Army Community Hospital secure LEED® Platinum Certification as the World’s First Carbon-Neutral Hospital.

About the Facility

The Weed Army Community Hospital is located at Fort Irwin, CA and is a state-of-the-art facility developed using evidence-based design for solar energy implementation. In addition, the facility is the world’s first carbon-neutral hospital and has achieved LEED® Platinum Certification, the highest qualification rating attainable for energy and resource efficiency in design and construction.

21.7% Decreased Energy Usage

Scope of Work

Acting as owner representative, SEA’s on-site certified energy manager was instrumental in the development of the building’s infrastructure. Working with the design team and early in the planning phases, SEA used its energy modeling tools to create nine major energy conservation measures that decreased overall ASHRAE code calulated energy usage by 21.7%. These measures reduced greenhouse gas emissions by 1,403 metric tons per year below the baseline. Additionally, renewable energy systems, including a solar photovoltaic (PV) array and a solar thermal array, take advantage of the site’s solar irradiance potential to meet all of the hospital’s energy and hot water requirements. 

Over $2M in rebates were secured to help minimize the initial costs. SEA led the commissioning of all mechanical and electrical systems to ensure that they performed as designed. In 2012, the design team received an Honor Award for Conceptional Design from the Chief of Engineers Awards of Excellence Program.
