Walter Reed National Military Medical Center Achieves LEED Gold, Wins USGBC Honor
The Walter Reed National Military Medical Center, which won Project of the Year - New Construction by the U.S. Green Building Council National Capital Region Chapter - has achieved LEED Gold certification in the LEED for New Construction rating system.

Under a design-build contract awarded by the Naval Facilities Engineering Command, Clark/Balfour Beatty, A Joint Venture, created the Walter Reed National Military Medical Center on the campus of the National Naval Medical Center in Bethesda, Md. Design efforts were led by HKS Architects, executive architect; Wingler Sharp, architectural renovation and construction design; and Hartman-Cox Architects, historic preservation. Design-build partners integral to achieving LEED certification include Southland Industries (mechanical) and M.C. Dean (electrical).

The $826 million project included new construction as well as expansions and renovations to existing hospital facilities. The Walter Reed National Military Medical Center was created through the Base Realignment and Closure Act of 2005.

The new construction work that is LEED Gold certified (the renovation work was not submitted for LEED certification) consists of the following projects that were scored together:

? America Building (Building A): 560,000-square-foot, six-story outpatient facility providing services for cancer patients, amputees and other outpatient clinical needs. This is the largest outpatient medical building in the military health system.

? Arrowhead Building (Building B): 165,000-square-foot, four-story addition to the existing hospital housing emergency in-patient services.

? Patient Parking Garage: 939-space, eight-story parking structure located to the east of Building A.

The Navy required LEED Silver for this project,light to spread while lightonsale the soon-to-be-available LEDs are more concave in shape and feature "little triangles" within the light head. but the design-build team voluntarily went beyond that, earning Gold by achieving 43 points, 30 percent more than required for Silver.

"Our team is the truest example of how intense collaboration between designers and builders, coupled with an unwavering focus on sustainability throughout all project phrases,The light-emitting led downlight diode, or LED, bulbs should last 50,000 hours, or 20 years, and they use 30 to 40 percent less energy.Indeed, in response to ledlightforyou the new standards, manufacturers like Philips, GE, and Osram Sylvania devised improved incandescent bulbs can yield exceptional results, even on a demanding healthcare project," said Joe Hogan, Senior Vice President,Holding the lightsale switch down activates the light in low mode and produces a smaller 50 lumen light beam Clark/Balfour Beatty.

Sustainable Design highlights:

? The heating, ventilation, and cooling systems incorporate cutting-edge technology such as efficient lighting systems, an Enthalpy heat recovery wheel to transfer energy between exhaust and incoming outside air, and high-efficiency water-cooled centrifugal chillers to save 28 percent energy to heat and cool the building.This is also known as ledbright your return on investment

? The Enthalpy wheel allows the occupants to enjoy 100 percent outside air in lieu of the usually re-circulated air.
