The National Intrepid Center of Excellence (NICoE), located at the National Naval Medical Center in Bethesda, MD, is a state of the art facility for veterans and military personnel with traumatic brain injuries and psychological issues. The building will provide advanced services through research, diagnosis, and treatment. Two distinct zonal areas make up the building’s composition. The “L” shape is located on the east and south sides and contains spaces dedicated to the clinical function of the facility. The remaining amorphous form is positioned on the north and west areas of the site, housing the healing and public areas of the building, including the open lobby, waiting rooms, lounge, auditorium, and rehabilitation rooms. There are also indoor/outdoor spaces for patients and families to relax and interact.
One of the main focuses of this report was to research and redesign the lighting and electrical systems in four distinct spaces within the building: the exterior façade, main lobby, auditorium, and physical and occupational therapy spaces. The main concept portrayed in the design is the qualities of a soldier. The goal was for the occupants to feel comfortable and appreciated in each space. The characteristics of unity, leadership, focus, and strength are presented through unique lighting designs that are functional and meet the special needs of each patient. The presence of daylight and the necessity for daylight controls was also closely examined.
The existing electrical design was altered to accommodate for these new lighting features. Modifications were completed within the power distribution system, including the addition of advanced controls. A study was completed to determine the effects of voltage drop on the existing feeder sizes. The voltage drop and energy reduction produced through increasing the wire sizes was analyzed. A detailed electrical system study using the SKM software helped to determine the coordination among various system components.
In order to fully integrate all of the building systems in the auditorium space, a redesign of distinct architectural features was completed. It is important that all components within the space work together to achieve optimum performance.
Lastly, a comparison of the cooling loads from different wall systems in the physical and occupational therapy space is included. The removal of the clerestory as a daylighting element resulted in a significant change in the mechanical loads within the space.
The report provides the details, process, and conclusions of a wide range of research and system studies. The proposed elements will enable NICoE to exhibit high functional and aesthetic performance.
